Medical Surgical Question 1: A 60-year-old male with a history of hypertension is admitted with confusion and muscle weakness. His serum sodium level is 115 mEq/L. Which intravenous (IV) therapy is the initial treatment of choice to raise his serum sodium levels safely?
A) Normal Saline (0.9% NaCl)
B) 5% Dextrose in Water (D5W)
C) Hypertonic Saline (3% NaCl)
D) Lactated Ringer’s (LR)
Explanation: This patient presents with severe hyponatremia (low serum sodium levels) and neurological symptoms such as confusion and muscle weakness. The initial treatment of choice to raise serum sodium levels safely in this scenario is Hypertonic Saline (3% NaCl). This solution provides a higher concentration of sodium, allowing for a controlled and gradual increase in serum sodium levels while reducing the risk of osmotic demyelination syndrome (ODS). Normal saline (Option A) is isotonic and won’t effectively correct severe hyponatremia. 5% Dextrose in Water (Option B) is a hypotonic solution that can further dilute sodium levels and is not suitable for acute correction. Lactated Ringer’s (Option D) is not the first-line choice for raising serum sodium levels in severe hyponatremia. Electrolytes, Intravenous fluids

Medical Surgical Question 3: A 60-year-old male with advanced pancreatic cancer is receiving total parenteral nutrition (TPN) due to severe malnutrition. What is a common complication associated with long-term TPN use that should be monitored in this patient?
A) Hyperglycemia
B) Hyperkalemia
C) Hypernatremia
D) Hypoglycemia
E) Hypokalemia
QBankProAcademy.com
Explanation: A common complication associated with long-term total parenteral nutrition (TPN) use is hyperglycemia (Option A). TPN solutions often contain high concentrations of glucose, and patients receiving TPN are at risk of elevated blood glucose levels. Close monitoring and insulin therapy may be necessary to manage hyperglycemia in these patients. While other electrolyte imbalances like hyperkalemia (Option B) and hypernatremia (Option C) can occur, hyperglycemia is a more prevalent concern in TPN. Hypoglycemia (Option D) and hypokalemia (Option E) are less common in patients receiving TPN, but they should still be monitored. Electrolytes, Intravenous fluids

Medical Surgical Question 9: A 55-year-old female with chronic laxative use presents with hyperphosphatemia (serum phosphate level of 9.5 mg/dL). Which intravenous (IV) medication is ta possible treatment to lower her phosphate levels acutely?
A) Calcium gluconate
B) Sodium bicarbonate
C) Albuterol
D) Phosphorus binder (e.g., sevelamer)
QBankproAcademy.com
Explanation: This patient presents with hyperphosphatemia, often seen in as a complication in chronic kidney disease. The initial treatment of choice to lower phosphate levels acutely is Calcium gluconate (Option A) and fluid resusciation. Calcium gluconate must be administered with extreme caution. The calcium binds to phosphate in the blood, forming calcium phosphate complexes that are then excreted by the kidneys. This helps lower serum phosphate levels. There is a theoretical risk o metastatic calcifications. Sodium bicarbonate (Option B) may be used in some cases to shift phosphate into cells temporarily but is not the primary treatment for hyperphosphatemia. Albuterol (Option C) may be considered for its potential to shift potassium intracellularly, but it is not effective for lowering phosphate levels. Phosphorus binders like sevelamer (Option D) are used for long-term management of hyperphosphatemia but are not for acute lowering of phosphate levels. Electrolytes, Intravenous fluids

Medical Surgical Question 24: A 55-year-old male with a history of severe pancreatitis has been unable to tolerate oral intake for the past week. He is experiencing significant weight loss and malnutrition. Which nutrient should be closely monitored to prevent refeeding syndrome in this patient receiving total parenteral nutrition (TPN)?
A) Sodium
B) Potassium
C) Phosphate
D) Magnesium
E) Calcium
QBankproAcademy.com
Explanation: In patients receiving total parenteral nutrition (TPN) after a period of inadequate nutrition, there is a risk of refeeding syndrome, which is characterized by severe electrolyte shifts. One of the key electrolytes to monitor closely is phosphate (Option C). Refeeding can lead to an abrupt uptake of phosphate by cells, causing hypophosphatemia, which can result in muscle weakness, respiratory failure, and cardiac arrhythmias. While monitoring other electrolytes like sodium, potassium, magnesium, and calcium is important in TPN, phosphate requires special attention in preventing refeeding syndrome. Electrolytes, Nutrition
Medical Surgical Question 25: A 40-year-old female with Crohn’s disease has undergone multiple surgeries and has severe malabsorption issues. She requires total parenteral nutrition (TPN) for long-term nutritional support. What type of central venous access device is most appropriate for her TPN administration?
A) Peripherally inserted central catheter (PICC)
B) Subclavian catheter
C) Peripheral intravenous (IV) line
D) Tunneled catheter
E) Implantable port
QBankproAcademy.com
Explanation: For long-term total parenteral nutrition (TPN) administration, a peripherally inserted central catheter (PICC) (Option A) is a suitable choice. PICCs can remain in place for an extended duration, reducing the need for repeated catheter insertion. They are inserted through a peripheral vein and threaded into a central vein, providing stable access for TPN delivery. Subclavian catheters (Option B) and tunneled catheters (Option D) are alternatives but are typically used when PICC placement is not feasible. Peripheral intravenous (IV) lines (Option C) are suitable for short-term use but are not appropriate for long-term TPN. Implantable ports (Option E) may also be considered for long-term TPN but involve a more invasive procedure for placement. Nutrition
Medical Surgical Question 26: A 60-year-old patient with sepsis is receiving vasopressor therapy and has persistent hypotension. The patient’s central venous pressure (CVP) measurement is low. What intervention should be considered to optimize fluid management in this patient?
A) Administer a diuretic
B) Increase the vasopressor dose
C) Administer colloids
D) Perform a fluid bolus
E) Discontinue vasopressor therapy
QBankproAcademy.com
Explanation: In a patient with sepsis who has persistent hypotension and a low central venous pressure (CVP), the appropriate intervention to optimize fluid management is to perform a fluid bolus (Option D). Fluid boluses with crystalloids are commonly used to increase intravascular volume in sepsis to improve cardiac preload and organ perfusion. Administering a diuretic (Option A) would reduce intravascular volume and worsen hypotension. Increasing the vasopressor dose (Option B) may be necessary in some cases but does not directly address intravascular volume. Administering colloids (Option C) is an option but may not be the initial step. Discontinuing vasopressor therapy (Option E) without addressing intravascular volume would likely worsen hypotension. IV Fluids, Sepsis
Medical Surgical Question 27: A 50-year-old female with severe burns covering 40% of her body surface area is receiving total parenteral nutrition (TPN) to support her nutritional needs during the acute phase of her treatment. Which nutrient should be provided at an increased rate in her TPN formula to support wound healing?
A) Carbohydrates
B) Protein
C) Lipids
D) Vitamins
E) Electrolytes
QBankproAcademy.com
Explanation: In patients with severe burns, protein (Option B) intake should be increased in the total parenteral nutrition (TPN) formula to support wound healing and tissue repair. Protein is essential for the synthesis of new tissue and the immune response required during the recovery phase of burn injuries. While carbohydrates (Option A), lipids (Option C), vitamins (Option D), and electrolytes (Option E) are important components of TPN, increasing protein is particularly crucial in burn patients to aid in the healing process and reduce the risk of muscle wasting.
Medical Surgical Question 28: A 35-year-old male with short bowel syndrome is receiving total parenteral nutrition (TPN) to compensate for malabsorption. He develops fever, chills, and hypotension. What is the most likely complication of long-term TPN use in this patient?
A) Catheter-related bloodstream infection (CRBSI)
B) Thrombophlebitis
C) Catheter dislodgement
D) Hyperglycemia
E) Electrolyte imbalance
QBankproAcademy.com
Explanation: In patients receiving long-term total parenteral nutrition (TPN), the most likely complication is catheter-related bloodstream infection (CRBSI) (Option A). The presence of a central venous catheter increases the risk of microbial contamination and subsequent bloodstream infection. Symptoms such as fever, chills, and hypotension are indicative of a CRBSI. While thrombophlebitis (Option B), catheter dislodgement (Option C), hyperglycemia (Option D), and electrolyte imbalance (Option E) can also occur, CRBSI is a significant concern and requires prompt diagnosis and treatment to prevent severe complications.
Medical Surgical Question 29: A 45-year-old female with Crohn’s disease has been on total parenteral nutrition (TPN) for an extended period due to her inability to tolerate oral intake. She is concerned about the risk of liver complications associated with long-term TPN use. Which of the following liver conditions is commonly associated with prolonged TPN?
A) Fatty liver disease
B) Cirrhosis
C) Hepatitis A
D) Gallstones
E) Cholecystitis
QBankproAcademy.com
Explanation: Prolonged use of total parenteral nutrition (TPN) is commonly associated with the development of fatty liver disease (Option A) in patients. This condition is known as parenteral nutrition-associated liver disease (PNALD) or total parenteral nutrition-associated liver disease (TPNALD). It is characterized by the accumulation of fat in the liver, which can progress to more severe liver complications. While cirrhosis (Option B), hepatitis A (Option C), gallstones (Option D), and cholecystitis (Option E) can affect the liver, fatty liver disease is a specific concern in patients on long-term TPN, and monitoring for its development is essential.

A) Malabsorption syndrome
B) Hyperglycemia
C) Catheter-related bloodstream infection (CRBSI)
D) Cholelithiasis
E) Electrolyte imbalance
QBankproAcademy.com
Explanation: A common complication associated with total parenteral nutrition (TPN) is the development of cholelithiasis (gallstones) (Option D). Patients receiving TPN are at an increased risk of gallstone formation due to reduced gallbladder contractility and the absence of normal enteral nutrition. Gallstones can lead to symptoms such as diarrhea and abdominal cramping. While malabsorption syndrome (Option A), hyperglycemia (Option B), CRBSI (Option C), and electrolyte imbalances (Option E) can occur with TPN, cholelithiasis is a specific concern related to the absence of enteral feeding.

Discontinuing phenytoin (Option B) can increase the risk of seizures. Switching to a different antiepileptic medication (Option C) may not be necessary unless there are specific concerns or indications. Administering an additional dose of phenytoin (Option D) before surgery is not typically required for patients on stable antiepileptic therapy.
Medical Surgical Question 40: A 45-year-old female with a history of rheumatoid arthritis is scheduled for elective surgery. She takes daily methotrexate for disease management. What is the most appropriate action regarding her methotrexate therapy before surgery?
A) Continue methotrexate therapy as usual
B) Discontinue methotrexate 1 week before surgery
C) Switch to a different disease-modifying antirheumatic drug (DMARD) before surgery
D) Initiate corticosteroid therapy before surgery
QBankproAcademy.com
Explanation: In patients with rheumatoid arthritis scheduled for surgery who are taking methotrexate, it is generally recommended to discontinue methotrexate therapy 1 week before surgery (Option B) to reduce the risk of impaired wound healing. Methotrexate can suppress the immune system and affect tissue repair. The medication can be resumed after the surgical site has adequately healed. Switching to a different disease-modifying antirheumatic drug (DMARD) (Option C) or initiating corticosteroid therapy (Option D) may be considered in consultation with the patient’s rheumatologist based on the clinical status and surgical requirements.
Medical Surgical Question 41: A 55-year-old male with a history of chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs) for osteoarthritis is scheduled for elective surgery. What should be considered regarding his NSAID use before surgery?
A) Continue NSAID use as usual
B) Discontinue NSAID use 1 day before surgery
C) Switch to a different analgesic before surgery
D) Administer a proton pump inhibitor (PPI) before surgery
QBankproAcademy.com
Explanation: In patients with chronic NSAID use scheduled for surgery, it is generally recommended to discontinue NSAID use (Option B) several days before the procedure to reduce the risk of perioperative bleeding. Continuing NSAID use (Option A) can increase the risk of bleeding during and after surgery. Switching to a different analgesic, such as acetaminophen or an stronger pain medication, is often a suitable alternative for pain management. Administering a proton pump inhibitor (PPI) (Option D) may help mitigate the risk of gastrointestinal bleeding but should be considered in conjunction with discontinuation of NSAIDs.

Medical Surgical Question 54: A 65-year-old male with a history of coronary artery disease (CAD) is undergoing elective coronary artery bypass grafting (CABG) surgery. During the procedure, the surgeon encounters severe bleeding from a graft site. What is the most appropriate initial intervention to manage the bleeding?
A) Apply direct pressure to the graft site
B) Administer a bolus of intravenous (IV) crystalloid fluid
C) Administer a bolus of intravenous (IV) vasopressor
D) Request a blood transfusion from the blood bank
QBankproAcademy.com
Explanation: Intraoperative bleeding during coronary artery bypass grafting (CABG) surgery can be a critical situation. The most appropriate initial intervention to manage the bleeding is to apply direct pressure to the graft site (Option A). This direct approach can help control the bleeding until further measures, such as additional sutures or blood products, can be arranged. Administering a bolus of intravenous (IV) crystalloid fluid (Option B) may be necessary for hemodynamic support but does not directly address the bleeding source. Administering a bolus of intravenous (IV) vasopressor (Option C) may exacerbate the bleeding and is not appropriate in this context. Requesting a blood transfusion from the blood bank (Option D) may be needed eventually, but it should not be the initial step in managing active bleeding.
Medical Surgical Question 55: A 50-year-old female is undergoing abdominal surgery. The anesthesia provider administers a neuromuscular blocking agent as part of the anesthesia induction process. After the surgery, the patient is not adequately reversing the neuromuscular blockade. Which medication should be administered to reverse the effects of the neuromuscular blocking agent?
A) Naloxone (Narcan)
B) Flumazenil (Romazicon)
C) Neostigmine (Prostigmin)
D) Epinephrine (Adrenaline)
QBankproAcademy.com
Explanation: To reverse the effects of a neuromuscular blocking agent, such as rocuronium or vecuronium, the appropriate medication is neostigmine (Option C) in combination with an anticholinergic agent like atropine to prevent excessive bradycardia. Neostigmine works by inhibiting acetylcholinesterase, leading to an accumulation of acetylcholine at the neuromuscular junction and subsequent muscle contraction. Naloxone (Option A) is used to reverse overdose, not neuromuscular blockade. Flumazenil (Option B) is used to reverse the effects of benzodiazepines, not neuromuscular blockade. Epinephrine (Option D) is a sympathomimetic agent and is not used to reverse neuromuscular blockade.
Medical Surgical Question 56: A 40-year-old male is undergoing a laparoscopic cholecystectomy. During the procedure, the surgeon accidentally punctures the patient’s common bile duct. Bile is leaking into the abdominal cavity. What is the most appropriate action to manage this intraoperative complication?
A) Close the abdominal incisions and proceed with the surgery
B) Administer intravenous (IV) antibiotics to prevent infection
C) Place a drainage tube in the abdominal cavity to collect bile
D) Convert the laparoscopic procedure to an open cholecystectomy
QBankproAcademy.com
Explanation: Accidental puncture of the common bile duct during laparoscopic cholecystectomy is a serious intraoperative complication that requires immediate attention. The most appropriate action is to convert the laparoscopic procedure to an open cholecystectomy (Option D) to better visualize and repair the injury. Closing the abdominal incisions and proceeding with the surgery (Option A) can lead to further complications. Administering intravenous (IV) antibiotics (Option B) is important but should be done in conjunction with addressing the bile duct injury. Placing a drainage tube in the abdominal cavity (Option C) is not sufficient to manage this type of injury and should be followed by open surgical repair.
Medical Surgical Question 57: A 55-year-old female is undergoing a total knee replacement surgery. The surgeon has just made an incision and is preparing to dissect through the tissue layers. Suddenly, the patient experiences a significant drop in blood pressure and heart rate. What is the most likely cause of this intraoperative hemodynamic instability?
A) Anesthesia-induced hypotension
B) Surgical site infection
C) Allergic reaction to surgical drapes
D) Hemorrhage into the surgical site
QBankProAcademy.com
Explanation: Intraoperative hemodynamic instability with a sudden drop in blood pressure and heart rate is most likely due to hemorrhage into the surgical site (Option D). This can occur when a blood vessel is inadvertently injured during the surgical dissection. Anesthesia-induced hypotension (Option A) is less likely to cause a sudden drop in both blood pressure and heart rate. Surgical site infection (Option B) and allergic reactions to surgical drapes (Option C) typically do not manifest as sudden hemodynamic instability during surgery. Cardiac, Cardiovascular
Medical Surgical Question 58: A 65-year-old male is undergoing a craniotomy for the removal of a brain tumor. During the surgery, the patient develops an acute rise in intracranial pressure (ICP). What is the most appropriate intervention to manage this intraoperative complication?
A) Administer intravenous (IV) diuretics
B) Increase the depth of anesthesia
C) Hyperventilate the patient to lower PaCO2
D) Notify the surgeon to halt the procedure
QBankproAcademy.com
Explanation: An acute rise in intracranial pressure (ICP) during a craniotomy is a critical intraoperative complication that requires immediate attention. The most appropriate intervention is to notify the surgeon to halt the procedure (Option D) so that the underlying cause of the ICP elevation can be assessed and addressed. Administering intravenous (IV) diuretics (Option A) or increasing the depth of anesthesia (Option B) may not be sufficient to manage the acute ICP rise. Hyperventilating the patient to lower PaCO2 (Option C) may be considered in some cases but should be done under the guidance of the anesthesia provider and surgeon.
Medical Surgical Question 59: A 50-year-old female is undergoing a laparoscopic appendectomy for acute appendicitis. During the surgery, the patient’s end-tidal carbon dioxide (EtCO2) levels suddenly rise significantly. What is the most likely cause of this intraoperative finding?
A) Anesthetic overdose
B) Pneumothorax
C) Carbon dioxide insufflation
D) Ventilator malfunction
QBankproAcademy.com
Explanation: A sudden significant rise in end-tidal carbon dioxide (EtCO2) levels during laparoscopic surgery is most likely due to pneumothorax (Option B). This can occur if the Veress needle or trocars used to establish pneumoperitoneum inadvertently puncture the pleural space, leading to air entering the thoracic cavity. Anesthetic overdose (Option A) would typically lead to decreased EtCO2 levels. Carbon dioxide insufflation (Option C) is a routine part of laparoscopic surgery and would not cause a sudden rise in EtCO2. Ventilator malfunction (Option D) is less likely to result in a significant increase in EtCO2 levels.
Medical Surgical Question 60: A 45-year-old male is undergoing emergency surgery for acute abdominal pain and suspected bowel perforation. During the procedure, the surgeon discovers a perforated segment of the small bowel. What is the most appropriate intraoperative intervention for managing this bowel perforation?
A) Close the perforation with sutures
B) Apply a tissue adhesive over the perforation
C) Place a drainage tube in the abdominal cavity
D) Resect the affected segment of the bowel
QBankproAcademy.com
Explanation: In the case of a perforated segment of the small bowel, the most appropriate intraoperative intervention is to resect the affected segment of the bowel (Option D). This is typically done to remove the damaged tissue and prevent contamination of the abdominal cavity. Closing the perforation with sutures (Option A) or applying tissue adhesive (Option B) alone is insufficient, as it does not address the underlying problem. Placing a drainage tube in the abdominal cavity (Option C) may be necessary but should be done after the resection to manage any residual infection or fluid accumulation.
Medical Surgical Question 61: A 60-year-old female is undergoing a laparoscopic hysterectomy for uterine fibroids. During the surgery, the patient’s oxygen saturation (SpO2) begins to drop, and the capnography waveform shows a sudden increase in end-tidal carbon dioxide (EtCO2). What is the most likely cause of this intraoperative finding?
A) Pulmonary embolism
B) Anesthesia machine malfunction
C) Electrocautery smoke inhalation
D) Endotracheal tube displacement
QBankproAcademy.com
Explanation: A sudden drop in oxygen saturation (SpO2) and a significant increase in end-tidal carbon dioxide (EtCO2) during surgery are concerning for a pulmonary embolism (Option A). This life-threatening condition occurs when a blood clot obstructs pulmonary arteries, leading to impaired oxygenation and increased EtCO2 as carbon dioxide accumulates in the blood. Anesthesia machine malfunction (Option B) would typically not cause this pattern. Electrocautery smoke inhalation (Option C) can lead to increased EtCO2 but is less likely to cause a drop in SpO2. Endotracheal tube displacement (Option D) can also lead to increased EtCO2, but it is less likely to cause a sudden drop in SpO2.
Medical Surgical Question 62: A 55-year-old male is undergoing a laparoscopic cholecystectomy. During the procedure, the patient’s blood pressure drops significantly, and there is evidence of active bleeding from a small artery near the gallbladder. What is the most appropriate intraoperative intervention to manage this bleeding?
A) Apply pressure to the bleeding artery with a surgical sponge
B) Administer a vasopressor to raise blood pressure
C) Place a vascular clamp on the bleeding artery
D) Request a blood transfusion from the blood bank
QBankproAcademy.com
Explanation: Intraoperative bleeding from a small artery near the gallbladder during a laparoscopic cholecystectomy requires immediate attention. The most appropriate intervention is to place a vascular clamp on the bleeding artery (Option C) to control the hemorrhage. Applying pressure with a surgical sponge (Option A) may not be sufficient for effective hemostasis in this situation. Administering a vasopressor (Option B) is not the primary intervention for controlling surgical bleeding. Requesting a blood transfusion from the blood bank (Option D) may be needed eventually if significant blood loss occurs, but it should not be the initial step in managing active bleeding.
Medical Surgical Question 63: A 65-year-old male underwent a total hip replacement surgery. On the first postoperative day, he reports severe pain at the surgical site despite receiving scheduled analgesics. The surgical wound appears normal, without signs of infection. What should be the nurse’s initial action?
A) Administer an additional dose of the prescribed analgesic
B) Notify the surgeon about the patient’s pain
C) Reassure the patient that postoperative pain is normal
D) Schedule a follow-up appointment in a week
QBankproAcademy.com
Explanation: Severe postoperative pain that is not effectively managed with prescribed analgesics should be a cause for concern. The nurse’s initial action should be to notify the surgeon (Option B) to ensure that there are no complications or issues with the surgical site that are contributing to the pain. Administering an additional dose of analgesic (Option A) without addressing the underlying cause of the pain may not be effective. Reassuring the patient (Option C) without further assessment or intervention is not appropriate in this situation. Scheduling a follow-up appointment in a week (Option D) is too delayed for addressing the immediate pain concern.
Medical Surgical Question 64: A 55-year-old female underwent abdominal surgery and has been prescribed pain medication for postoperative pain management. On the second postoperative day, she reports constipation and abdominal discomfort. What is the most appropriate nursing intervention to address this issue?
A) Administer an additional dose of pain medication to manage pain
B) Encourage the patient to increase fluid intake and ambulation
C) Instruct the patient to stop all pain medications immediately
D) Recommend a high-fiber diet to relieve constipation
QBankproAcademy.com
Explanation: Postoperative constipation is a common issue that can be managed effectively with non-pharmacological measures. The most appropriate nursing intervention is to encourage the patient to increase fluid intake and ambulation (Option B). These measures can help alleviate constipation without compromising pain management. Administering an additional dose of pain medication (Option A) may exacerbate the constipation and is not recommended. Instructing the patient to stop all medications (Option C) without an alternative pain management plan would lead to inadequate pain control. Recommending a high-fiber diet (Option D) is a good long-term strategy but may not provide immediate relief from constipation.
Medical Surgical Question 65: A 40-year-old male underwent laparoscopic appendectomy for acute appendicitis. On the third postoperative day, the patient experiences sudden-onset severe right lower abdominal pain, and the surgical site becomes red, swollen, and warm to touch. What is the most likely complication, and what should the nurse do?
A) Seroma formation; continue to monitor
B) Surgical site infection; notify the surgeon
C) Normal postoperative pain; administer analgesics
D) Incisional hernia; apply an abdominal binder
QBankproAcademy.com
Explanation: The sudden-onset severe pain, redness, swelling, and warmth at the surgical site are indicative of a surgical site infection (SSI), a serious postoperative complication. The nurse’s immediate action should be to notify the surgeon (Option B) for assessment and treatment. Continuing to monitor (Option A) would not be appropriate when signs of infection are present. Attributing the symptoms to normal postoperative pain (Option C) without further assessment can delay treatment. Incisional hernia (Option D) typically presents differently and should not be the initial suspicion in this case.
Medical Surgical Question 66: A 60-year-old female underwent abdominal surgery. She has a history of deep vein thrombosis (DVT). Which postoperative prophylactic measure should be prioritized for this patient to prevent DVT?
A) Early ambulation
B) Administration of antiemetics
C) Deep breathing exercises
D) Continuous passive motion machine
QBankproAcademy.com
Explanation: In a patient with a history of deep vein thrombosis (DVT) undergoing surgery, early ambulation (Option A) is a priority prophylactic measure to prevent DVT. Mobilization helps improve venous return and reduces the risk of venous stasis. While deep breathing exercises (Option C) are important for preventing respiratory complications, they do not directly address DVT prevention. Administration of antiemetics (Option B) and the use of a continuous passive motion machine (Option D) are not primary measures for DVT prevention.
Medical Surgical Question 67: A 45-year-old male underwent elective hernia repair surgery. On the second postoperative day, he experiences shortness of breath, chest pain, and oxygen saturation (SpO2) of 89%. What is the most likely postoperative complication, and what should the nurse do?
A) Surgical site infection; administer antibiotics
B) Atelectasis; encourage deep breathing exercises
C) Pulmonary embolism; notify the healthcare provider
D) Gastrointestinal bleeding; administer a proton pump inhibitor
QBankproAcademy.com
Explanation: The sudden onset of shortness of breath, chest pain, and decreased oxygen saturation (SpO2) is highly suggestive of a pulmonary embolism (PE), a severe postoperative complication. The nurse’s immediate action should be to notify the healthcare provider (Option C) for further evaluation and intervention. Administering antibiotics (Option A), encouraging deep breathing exercises (Option B), or administering a proton pump inhibitor (Option D) would not address the underlying issue of a suspected PE and could delay appropriate treatment.
Medical Surgical Question 68: A 70-year-old female underwent a total knee replacement surgery. On the first postoperative day, she complains of calf pain, tenderness, and swelling in the affected leg. What is the most likely postoperative complication, and what should the nurse do?
A) Cellulitis; administer antibiotics
B) Superficial thrombophlebitis; apply warm compresses
C) Deep vein thrombosis (DVT); notify the healthcare provider
D) Muscular strain; encourage rest and pain management
QBankproAcademy.com
Explanation: The symptoms of calf pain, tenderness, and swelling in the affected leg are concerning for deep vein thrombosis (DVT), a common postoperative complication. The nurse’s immediate action should be to notify the healthcare provider (Option C) for further evaluation and consideration of diagnostic imaging. Administering antibiotics (Option A) would not address DVT. Superficial thrombophlebitis (Option B) may present with similar symptoms but is less severe than DVT. Attributing the symptoms to muscular strain (Option D) without proper assessment can delay the diagnosis and treatment of DVT.
Medical Surgical Question 69: A 55-year-old male underwent open-heart surgery. On the third postoperative day, he develops a fever, productive cough, and increased sputum production. What is the most likely postoperative complication, and what should the nurse do?
A) Atelectasis; encourage deep breathing exercises
B) Surgical site infection; administer antibiotics
C) Pneumonia; notify the healthcare provider
D) Wound dehiscence; apply sterile dressings
QBankProAcademy.com
Explanation: The fever, productive cough, and increased sputum production are indicative of pneumonia, a common postoperative complication, especially after open-heart surgery. The nurse’s immediate action should be to notify the healthcare provider (Option C) for further evaluation and treatment. While deep breathing exercises (Option A) are important for preventing atelectasis, they are not the primary intervention for pneumonia. Administering antibiotics (Option B) without a proper evaluation and diagnosis could delay appropriate treatment. Wound dehiscence (Option D) is unrelated to the respiratory symptoms described. Cardiac, Cardiovascular
Medical Surgical Question 70: A 50-year-old female underwent abdominal surgery. On the second postoperative day, she complains of nausea and abdominal distention. The nurse notes decreased bowel sounds on auscultation. What is the most likely postoperative complication, and what should the nurse do?
A) Constipation; administer a laxative
B) Ileus; notify the healthcare provider
C) Urinary tract infection; obtain a urine culture
D) Gastroparesis; initiate enteral nutrition

D) Deep vein thrombosis (DVT)
E) Necrotizing fasciitis
QBankproAcademy.com
Explanation: The patient’s presentation with fever, chills, a swollen and erythematous upper extremity with visible red streaks is indicative of lymphangitis (Option C). Lymphangitis is an inflammation of the lymphatic vessels often seen as a response to localized infection. While sepsis (Option A), cellulitis (Option B), deep vein thrombosis (DVT) (Option D), and necrotizing fasciitis (Option E) can have some similar features, the presence of visible red streaks along the arm suggests lymphangitis as a primary concern in this patient.
Medical Surgical Question 98: A 62-year-old patient is admitted to the emergency department with a high fever, altered mental status, hypotension, and tachycardia. Laboratory tests reveal an elevated lactate level. The nurse suspects sepsis and initiates sepsis protocols. What is the first step in the management of sepsis for this patient?
A) Administer broad-spectrum antibiotics
B) Administer intravenous fluids
C) Start vasopressor therapy
D) Perform blood cultures
E) Administer corticosteroids
QBankproAcademy.com
Explanation: The initial step in the management of sepsis is to administer broad-spectrum antibiotics (Option A) as soon as possible to cover a wide range of potential pathogens. Timely antibiotic therapy is crucial in sepsis management to target the underlying infection. While intravenous fluids (Option B) are essential to address hypotension and organ perfusion, antibiotics take precedence. Vasopressor therapy (Option C) is indicated if hypotension persists despite fluid resuscitation. Performing blood cultures (Option D) is important to identify the specific pathogen but should not delay antibiotic administration. The use of corticosteroids (Option E) in sepsis management is not routinely recommended and should be considered in specific cases.
Medical Surgical Question 99: A 48-year-old patient with sepsis is receiving intravenous fluids and antibiotics. Despite initial interventions, the patient remains hypotensive. What is the next step in the management of sepsis for this patient?
A) Increase the rate of intravenous fluid administration
B) Administer vasopressor therapy
C) Perform a bedside ultrasound
D) Administer a blood transfusion
E) Consult a nephrologist
QBankproAcademy.com
Explanation: If a patient with sepsis remains hypotensive despite initial fluid resuscitation (Option A), the next step is to administer vasopressor therapy (Option B) to improve blood pressure and organ perfusion. Vasopressors such as norepinephrine are commonly used in septic shock to increase systemic vascular resistance and maintain blood pressure. Performing a bedside ultrasound (Option C) can help assess the patient’s volume status and cardiac function but should not delay vasopressor therapy in cases of refractory hypotension. Blood transfusion (Option D) may be indicated in cases of severe anemia but is not the primary intervention for hypotension in sepsis. Consulting a nephrologist (Option E) is not the immediate priority in the management of sepsis-related hypotension.
Medical Surgical Question 100: A 55-year-old patient with sepsis is receiving antibiotics and vasopressor therapy. Despite initial interventions, the patient’s lactate levels remain elevated. What additional intervention is indicated in the management of sepsis for this patient?
A) Increase the dose of vasopressors
B) Administer bicarbonate therapy
C) Initiate renal replacement therapy
D) Perform central venous oxygen saturation (ScvO2) monitoring
E) Administer anticoagulants
QBankproAcademy.com
Explanation: Persistent elevation of lactate levels in a patient with sepsis despite initial interventions may indicate the need for renal replacement therapy (Option C). This therapy, often in the form of continuous renal replacement therapy (CRRT), can help improve lactate clearance and remove metabolic waste products. Increasing the dose of vasopressors (Option A) should be considered if hypotension persists, but addressing the elevated lactate takes precedence. Bicarbonate therapy (Option B) is not routinely recommended for lactate elevation in sepsis. Monitoring central venous oxygen saturation (ScvO2) (Option D) can provide valuable information about oxygen delivery and consumption but does not directly address elevated lactate levels. Anticoagulants (Option E) are not indicated for lactate elevation in sepsis management.
Medical Surgical Question 101: A 70-year-old patient with sepsis develops acute kidney injury (AKI). The patient is already receiving intravenous fluids and vasopressor therapy. What additional intervention should be considered in the management of AKI in sepsis?
A) Initiate corticosteroid therapy
B) Perform a kidney biopsy
C) Administer nephrotoxic medications
D) Start continuous renal replacement therapy (CRRT)
E) Administer a blood transfusion
QBankproAcademy.com
Explanation: In a patient with sepsis who develops acute kidney injury (AKI) despite intravenous fluids and vasopressor therapy, the next step is to consider continuous renal replacement therapy (CRRT) (Option D). CRRT can provide renal support and help manage fluid and electrolyte imbalances in patients with severe AKI. Corticosteroid therapy (Option A) is not routinely recommended for AKI in sepsis. Kidney biopsy (Option B) is not the initial step in the management of AKI and is reserved for specific diagnostic purposes. Administering nephrotoxic medications (Option C) should be avoided in AKI management. Blood transfusion (Option E) may be indicated for severe anemia but is not the primary intervention for AKI. Renal, Sepsis
Studying meds for the Medical Surgical class. Diabetic medications are so important and your introduction to diabetes and diabetic meds for Type 1 diabetics and type 2 diabetics may begin in med surg.
Most Common Diabetic Meds
Metformin: Often considered the first-line treatment for type 2 diabetes, it helps lower blood sugar levels by reducing the amount of glucose produced by the liver and increasing the body’s sensitivity to insulin.
Sulfonylureas: These medications stimulate the pancreas to produce more insulin. They include drugs like glyburide, glipizide, and glimepiride.
DPP-4 inhibitors: These medications help lower blood sugar levels by increasing insulin release and decreasing the amount of glucose produced by the liver. Examples include sitagliptin, saxagliptin, and linagliptin.
SGLT2 inhibitors: These medications work by preventing the kidneys from reabsorbing glucose into the blood and instead help the body excrete excess glucose through urine. Canagliflozin, dapagliflozin, and empagliflozin are examples.
GLP-1 receptor agonists: They help lower blood sugar levels by stimulating insulin production and reducing the liver’s production of glucose. Examples include exenatide, liraglutide, and dulaglutide.
Insulin: Some people with diabetes, especially type 1 diabetes, require insulin therapy to manage their blood sugar levels. There are various types of insulin available, including rapid-acting, short-acting, intermediate-acting, and long-acting insulin.
Insulin
Rapid-acting insulin: This type of insulin starts working within 15 minutes after injection, peaks around 1 hour, and continues to work for 2 to 4 hours. Examples include insulin lispro (brand name: Humalog), insulin aspart (NovoLog), and insulin glulisine (Apidra).
Short-acting insulin: It typically starts working within 30 minutes, peaks in 2 to 3 hours, and remains effective for about 3 to 6 hours. Regular insulin (R) is an example, known as Humulin R or Novolin R.
Intermediate-acting insulin: This type of insulin has a slower onset of action, usually starting within 2 to 4 hours, peaking in 4 to 12 hours, and lasting up to 18 hours. Examples include NPH insulin (Neutral Protamine Hagedorn), such as Humulin N or Novolin N.
Long-acting insulin: It has a slow and steady release, providing a baseline insulin level for an extended period. These insulins start working in about 1 to 2 hours, have no pronounced peak, and can last from 18 to 24 hours or more. Examples include insulin glargine (Lantus, Basaglar, Toujeo), insulin detemir (Levemir), and insulin degludec (Tresiba).
Ultra-long-acting insulin: Some newer formulations offer even longer durations of action, providing basal insulin coverage for more than 24 hours. Insulin degludec (Tresiba) is an example, known for its longer duration and stable action.
Here Are Some Of The Newer Diabetic Medications
SGLT2 Inhibitors (Sodium-Glucose Co-Transporter 2 Inhibitors): Medications like empagliflozin (Jardiance), dapagliflozin (Farxiga), and canagliflozin (Invokana) are part of this class. They work by reducing the reabsorption of glucose by the kidneys, thereby lowering blood sugar levels. Additionally, they have shown benefits in reducing the risk of cardiovascular events and improving kidney function in people with diabetes.
GLP-1 Receptor Agonists (Glucagon-Like Peptide-1 Receptor Agonists): These medications include liraglutide (Victoza), dulaglutide (Trulicity), exenatide (Byetta), and semaglutide (Ozempic). They work by mimicking the action of GLP-1, a hormone that increases insulin secretion, decreases glucagon production, slows digestion, and helps regulate appetite. GLP-1 receptor agonists have shown benefits in weight management and cardiovascular health.
DPP-4 Inhibitors (Dipeptidyl Peptidase 4 Inhibitors): Medications such as sitagliptin (Januvia), saxagliptin (Onglyza), and linagliptin (Tradjenta) are part of this class. They work by blocking the enzyme DPP-4, which in turn increases the levels of incretin hormones. Incretins help regulate blood sugar levels by increasing insulin release and decreasing glucagon production.
Insulin Analogues: Newer formulations of insulin have been developed to provide more stable and prolonged effects, such as insulin degludec (Tresiba), which offers a longer duration of action compared to traditional insulins.
Combo Medications: Some newer medications combine different classes of diabetes drugs in a single pill to simplify dosing and improve adherence for patients.
Bile Acid Sequestrants: While traditionally used for managing cholesterol levels, medications like colesevelam have shown some promise in aiding glycemic control by binding to bile acids in the intestine, potentially lowering blood sugar levels.
Amylin Analogues: Pramlintide (Symlin) is an amylin analogue that mimics the hormone amylin, which is deficient in people with diabetes. It helps control post-meal blood sugar spikes by slowing gastric emptying and reducing glucagon secretion from the pancreas.
Glinides: Repaglinide and nateglinide are medications that stimulate the pancreas to release insulin rapidly, especially after meals. They have a shorter duration of action compared to sulfonylureas and can help control blood sugar levels during mealtime.
Dual or Triple Combination Therapies: Some medications combine two different classes of diabetes drugs or even three in some cases, providing a more comprehensive approach to managing blood sugar levels.
Gene Therapy and Novel Approaches: Research is ongoing in exploring gene therapy and novel mechanisms to target diabetes, aiming to provide more effective and targeted treatments with potentially fewer side effects.
