Rationale: Total bilirubin is a key indicator of impaired liver function, particularly in cases of liver disease or damage. Elevated levels suggest poor clearance of bilirubin by the liver, leading to jaundice. While other LFTs such as ALT and AST can also indicate liver damage, total bilirubin specifically assesses the liver’s ability to process bilirubin, making it the most relevant option in this scenario.

A client with a recent diagnosis of hepatitis C is being monitored for liver function. The nurse reviews the laboratory results and notes an elevated level of alkaline phosphatase (ALP). Which of the following conditions is most likely associated with an increased ALP in this client? a) Alcoholic liver disease b) Cirrhosis c) Acute viral hepatitis d) Biliary obstruction e) Non-alcoholic fatty liver disease (NAFLD)
Correct Answer: d) Biliary obstruction
Rationale: Elevated levels of alkaline phosphatase (ALP) are commonly associated with biliary obstruction. In conditions like hepatitis C, obstruction of the bile ducts can lead to impaired bile flow, resulting in increased ALP levels. The other options may cause liver damage but are not specifically linked to elevated ALP.

Rationale: Alanine aminotransferase (ALT) is a specific marker for liver inflammation and damage. In NAFLD, increased fat accumulation in the liver can lead to inflammation, causing elevated ALT levels. Monitoring ALT helps assess the severity of liver involvement in NAFLD and guides further management. Other LFTs may provide valuable information, but ALT is particularly relevant for evaluating inflammation in this context.

NCLEX Review: Liver Function Tests Disease Treatments

A 45-year-old patient with a history of chronic liver disease is undergoing routine liver function tests (LFTs). The nurse observes an elevated level of aspartate aminotransferase (AST) in the results. Which of the following conditions is most likely associated with an increased AST level? a) Alcoholic liver disease b) Hepatitis B infection c) Cirrhosis d) Cholecystitis e) Non-alcoholic fatty liver disease (NAFLD)
Correct Answer: a) Alcoholic liver disease
Rationale: Elevated levels of AST are often indicative of liver damage, and in this case, alcoholic liver disease is a common cause. AST is found in various tissues, including the liver, and an increase in its levels can signify hepatocellular damage. While other conditions may also affect the liver, alcoholic liver disease is specifically associated with elevated AST levels, making it the correct answer.

Understanding Liver Function Tests: NCLEX Priority Questions

A postoperative patient who underwent a cholecystectomy is being monitored for liver function. The nurse notes a decrease in serum albumin levels in the laboratory results. What is the most likely explanation for this finding? a) Liver cirrhosis b) Acute viral hepatitis c) Impaired absorption of nutrients d) Bile duct obstruction e) Surgical stress response
Correct Answer: a) Liver cirrhosis
Rationale: Serum albumin is synthesized by the liver, and a decrease in levels may be indicative of liver dysfunction. In the context of a patient post-cholecystectomy, liver cirrhosis is a condition that can lead to decreased albumin synthesis. While other options may contribute to changes in albumin levels, cirrhosis is specifically linked to impaired liver function and reduced albumin production.

Understanding Liver Function Tests: NCLEX Delegation Questions

A pregnant woman in her third trimester presents with itching and jaundice. Liver function tests are ordered to assess her condition. Which of the following LFTs is most relevant for evaluating intrahepatic cholestasis of pregnancy (ICP)? a) Alanine aminotransferase (ALT) b) Total bilirubin c) Prothrombin time (PT) d) Alkaline phosphatase (ALP) e) Serum albumin
Correct Answer: d) Alkaline phosphatase (ALP)
Rationale: Intrahepatic cholestasis of pregnancy (ICP) is characterized by impaired bile flow within the liver. Elevated levels of alkaline phosphatase (ALP) are commonly associated with cholestasis. Monitoring ALP is crucial in assessing liver function in pregnant women with ICP, as it reflects the cholestatic process. While other LFTs may show abnormalities, ALP is particularly relevant in this scenario.

Understanding Liver Function Tests: Causes and Symptoms

A 60-year-old patient with a history of heart failure is admitted to the hospital. The healthcare provider orders liver function tests (LFTs) as part of the routine assessment. The nurse reviews the results and notes an elevated level of serum albumin. Which of the following conditions is most likely associated with an increased serum albumin level in this patient? a) Cirrhosis b) Acute hepatitis c) Heart failure d) Biliary obstruction e) Non-alcoholic fatty liver disease (NAFLD)
Correct Answer: c) Heart failure
Rationale: In the context of heart failure, an elevated serum albumin level is often observed. This can be attributed to fluid retention and decreased plasma volume associated with heart failure. While other conditions may cause alterations in liver function, heart failure’s impact on fluid dynamics contributes to an increased serum albumin level, making it the correct answer.

NCLEX Practice Questions: Understanding Liver Function Tests Causes and Symptoms

A 30-year-old female presents to the clinic with complaints of abdominal pain and fatigue. The healthcare provider suspects liver dysfunction and orders liver function tests. The results show a significant elevation in aspartate aminotransferase (AST). Which of the following conditions is most likely associated with an increased AST level in this patient? a) Non-alcoholic fatty liver disease (NAFLD) b) Cirrhosis c) Hemochromatosis d) Cholecystitis e) Viral hepatitis
Correct Answer: e) Viral hepatitis
Rationale: Elevated AST levels are commonly seen in viral hepatitis, indicating hepatocellular damage. Viral hepatitis causes inflammation of the liver, leading to leakage of AST into the bloodstream. While other conditions may affect the liver, viral hepatitis, specifically, is strongly associated with increased AST levels, making it the correct answer in this scenario.

A middle-aged patient is undergoing chemotherapy for the treatment of cancer. The nurse reviews the laboratory results and notes a decrease in prothrombin time (PT). Which of the following conditions is most likely associated with a decreased PT in this patient? a) Liver cirrhosis b) Alcoholic liver disease c) Cholecystitis d) Impaired synthesis of clotting factors e) Acute viral hepatitis
Correct Answer: d) Impaired synthesis of clotting factors
Rationale: Prothrombin time (PT) measures the extrinsic pathway of coagulation and is prolonged in liver disease. However, in the context of a patient undergoing chemotherapy, a decrease in PT may be attributed to impaired synthesis of clotting factors rather than improved liver function. Chemotherapy can affect the production of clotting factors, leading to a shortened PT. Therefore, impaired synthesis of clotting factors is the most relevant explanation for the decreased PT in this scenario.
