Question 1: A 25-year-old female patient presents to the emergency department complaining of sudden difficulty breathing, wheezing, and tightness in the chest. She reports a history of asthma and states that she has been exposed to dust and pet dander recently. On assessment, she is using accessory muscles to breathe and has audible wheezing. Vital signs reveal increased respiratory rate and heart rate. What initial intervention should the nurse prioritize?
A. Administer a beta-agonist inhaler
B. Perform peak expiratory flow rate measurement
C. Apply oxygen therapy via nasal cannula
D. Administer corticosteroids via IV
E. Initiate a high-flow oxygen mask
QBankProAcademy.com
Rationale: In acute asthma exacerbation, the priority is to alleviate bronchoconstriction and improve airflow. Beta-agonist inhalers like albuterol are the first-line medications to achieve rapid bronchodilation. Peak expiratory flow rate measurement and oxygen therapy are important interventions, but initiating bronchodilator therapy takes precedence in managing acute symptoms. Corticosteroids via IV are used for sustained anti-inflammatory effects but are not immediate interventions. High-flow oxygen masks may be considered if the patient’s condition deteriorates despite initial interventions.

Question 2: A 30-year-old male with a history of asthma visits the clinic complaining of increased shortness of breath and coughing. He mentions exposure to cigarette smoke at work. On examination, wheezing is auscultated bilaterally, and the patient appears anxious. What action should the nurse prioritize to assess the severity of the asthma exacerbation?
A. Perform arterial blood gas analysis
B. Obtain a sputum culture
C. Measure peak expiratory flow rate
D. Conduct a chest X-ray
E. Administer a bronchodilator nebulizer treatment
QBankProAcademy.com
Rationale: Peak expiratory flow rate (PEFR) is a valuable tool in evaluating the severity of asthma exacerbation by assessing the degree of airflow limitation. It helps in determining the level of obstruction and guiding treatment. Arterial blood gas analysis may provide information on oxygenation but does not directly assess the severity of airflow limitation in asthma. Sputum culture, chest X-ray, and bronchodilator treatments are important but may not immediately aid in assessing the severity of the exacerbation.

Question 3: A 40-year-old female presents to the emergency department with acute respiratory distress. She has a known history of severe asthma and reports non-compliance with her maintenance inhalers. She is using accessory muscles to breathe, with minimal air movement heard bilaterally on auscultation. Oxygen saturation is low despite supplemental oxygen via nasal cannula. What is the most appropriate immediate nursing action?
A. Prepare for endotracheal intubation
B. Administer IV corticosteroids
C. Initiate continuous positive airway pressure (CPAP)
D. Perform a chest X-ray
E. Begin nebulized bronchodilator therapy
QBankProAcademy.com
Rationale: In severe asthma exacerbation leading to respiratory failure, airway protection and support are crucial. Endotracheal intubation helps maintain a patent airway, facilitates mechanical ventilation, and ensures oxygenation. IV corticosteroids are important for anti-inflammatory effects but do not address the immediate need for airway management. CPAP might be considered if the patient’s condition stabilizes, but in acute distress, intubation takes precedence. Chest X-ray and nebulized bronchodilators may provide additional information or treatment but are not immediate priorities in severe respiratory distress.

Question 4: A 35-year-old male with a history of asthma presents to the urgent care clinic complaining of coughing, chest tightness, and wheezing for the past two days. He reports using his albuterol inhaler without relief. On examination, he has prolonged expiration and diffuse wheezing upon auscultation. Which action should the nurse prioritize initially?
A. Administer a long-acting beta-agonist (LABA)
B. Perform a chest X-ray
C. Assess peak expiratory flow rate (PEFR)
D. Initiate oxygen therapy via nasal cannula
E. Provide oral corticosteroids
QBankProAcademy.com
Rationale: Assessing the peak expiratory flow rate helps gauge the severity of airflow obstruction and aids in determining the appropriate treatment for an asthma exacerbation. It guides therapy decisions and assists in monitoring the response to interventions. Administering a LABA, chest X-ray, and oxygen therapy are essential but are secondary to assessing the patient’s peak expiratory flow rate. Oral corticosteroids are typically part of the treatment regimen but may not be the immediate priority without assessing the severity of airflow limitation.

Question 5: A 28-year-old female with a history of allergic asthma reports increased shortness of breath and coughing after exposure to her friend’s cat. On assessment, she demonstrates audible wheezing and increased respiratory rate. She carries her rescue inhaler but has not used it yet. What intervention should the nurse initiate first?
A. Administer a leukotriene modifier
B. Perform allergy skin testing
C. Administer a rescue inhaler
D. Initiate a corticosteroid taper
E. Conduct pulmonary function tests
QBankProAcademy.com
Rationale: Administering a rescue inhaler containing a short-acting beta-agonist like albuterol is the immediate intervention to relieve acute bronchoconstriction and alleviate symptoms in an asthma exacerbation. Leukotriene modifiers and corticosteroids are part of long-term asthma management but are not the initial interventions for acute exacerbations. Allergy testing may be helpful in identifying triggers but does not address the immediate need for symptom relief. Pulmonary function tests are valuable for diagnosis and monitoring but are not the first step in managing acute symptoms.

Question 6: A 20-year-old male presents to the emergency department with severe asthma exacerbation following exposure to paint fumes. He is using accessory muscles to breathe, has minimal air movement on auscultation, and exhibits cyanosis. Initial treatments have provided no improvement. What should the nurse prepare for as the next step in management?
A. Administer continuous nebulized bronchodilators
B. Initiate non-invasive positive pressure ventilation (NIPPV)
C. Begin IV magnesium sulfate infusion
D. Prepare for endotracheal intubation
E. Administer IV antihistamines
QBankProAcademy.com
Rationale: In cases of severe asthma exacerbation with respiratory failure and inadequate response to initial treatments, securing the airway via endotracheal intubation is crucial to ensure adequate oxygenation and ventilation. Continuous nebulized bronchodilators, NIPPV, and IV magnesium sulfate are beneficial but are secondary to ensuring airway patency. IV antihistamines are not indicated in acute asthma exacerbations and will not address the immediate need for airway management.

Question 7: A 42-year-old female presents with chronic asthma and is prescribed an inhaled corticosteroid (ICS) along with a long-acting beta-agonist (LABA). She complains of occasional shortness of breath despite using her inhalers regularly. On assessment, she has decreased breath sounds and diffuse wheezing. What action should the nurse prioritize?
A. Increase the dosage of the LABA
B. Administer oral corticosteroids
C. Instruct proper inhaler technique
D. Switch to a leukotriene modifier
E. Perform a chest X-ray
QBankProAcademy.com
Rationale: Ensuring proper inhaler technique is crucial for optimal drug delivery and effectiveness of the medications. Inadequate inhaler technique can lead to poor asthma control despite using the prescribed medications. Increasing the LABA dosage or switching medications may not be necessary if the issue is improper technique. Oral corticosteroids and chest X-ray may be considered if symptoms persist after addressing inhaler technique, but ensuring proper use takes precedence.

Question 8: A 30-year-old female presents to the clinic with complaints of worsening asthma symptoms over the past week. She reports using her rescue inhaler more frequently and waking up at night due to coughing and wheezing. She denies any recent illnesses or changes in her environment. On examination, she has diffuse wheezing on auscultation. Which medication class is most commonly used for long-term control of persistent asthma?
A. Anticholinergics
B. Leukotriene modifiers
C. Short-acting beta-agonists
D. Mast cell stabilizers
E. Long-acting beta-agonists
QBankProAcademy.com
Rationale: Leukotriene modifiers, such as montelukast, zafirlukast, and zileuton, are commonly prescribed for long-term control of persistent asthma. They work by reducing airway inflammation and constriction. Anticholinergics and short-acting beta-agonists are used for acute symptom relief, while mast cell stabilizers like cromolyn sodium are more effective for preventing exercise-induced asthma. Long-acting beta-agonists are often used as adjunct therapy with inhaled corticosteroids but are not typically the first-line for long-term control.

Question 9: A 25-year-old male presents to the emergency department with an acute asthma exacerbation. He reports exposure to smoke at a bonfire the previous night and has been experiencing difficulty breathing, chest tightness, and audible wheezing. On assessment, he appears anxious and has decreased breath sounds with prolonged expiration. Which intervention should the nurse prioritize initially?
A. Administer oxygen therapy via nasal cannula
B. Start continuous nebulized albuterol
C. Perform arterial blood gas analysis
D. Administer IV corticosteroids
E. Assess peak expiratory flow rate (PEFR)
QBankProAcademy.com
Rationale: In an acute asthma exacerbation, the priority is to rapidly relieve bronchoconstriction and improve airflow. Continuous nebulized albuterol is an effective intervention for acute exacerbations to achieve prompt bronchodilation. Oxygen therapy, arterial blood gas analysis, and IV corticosteroids are essential but are secondary to providing immediate relief through bronchodilator therapy. Assessing PEFR is valuable but may not be as immediate or effective in managing acute symptoms.

Question 10: A 40-year-old female presents to the clinic for a follow-up visit for her asthma. She reports good adherence to her prescribed medications, including an inhaled corticosteroid (ICS) and a long-acting beta-agonist (LABA). Despite this, she continues to experience occasional wheezing and shortness of breath. On examination, her lung sounds are diminished with expiratory wheezing. What could be an appropriate addition to her current therapy to improve asthma control?
A. Oral corticosteroids
B. Leukotriene modifiers
C. Short-acting beta-agonists
D. Mast cell stabilizers
E. Anti-IgE monoclonal antibody therapy
QBankProAcademy.com
Rationale: For patients with persistent asthma despite ICS/LABA therapy, adding biologic agents like anti-IgE monoclonal antibodies (e.g., omalizumab) can be beneficial. These medications target specific inflammatory pathways and are indicated in severe allergic asthma cases. Oral corticosteroids are used for short-term control and have adverse effects with prolonged use. Leukotriene modifiers might be considered, but in severe cases, biologic agents like anti-IgE therapy are more effective. Short-acting beta-agonists and mast cell stabilizers are primarily for acute symptom relief and prevention of exercise-induced asthma, respectively.
