1. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

2. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

3. What health promotion teaching should prioritize to prevent drug-induced hepatitis?

• A. Finish all prescribed courses of antibiotics, regardless of symptom resolution
• B. Adhere to dosing recommendations of over-the-counter analgesics
• C. Ensure that expired medications are disposed of safely
• D. Ensure that pharmacists regularly review drug regimens for potential interactions

Correct answer: B

Rationale: Adhering to dosing recommendations of over-the-counter analgesics is crucial in preventing drug-induced hepatitis. Overdosing on analgesics can lead to liver damage, making it essential to follow the recommended dosages to reduce the risk of hepatotoxicity.

4. A client is admitted with a diagnosis of acute pancreatitis. Which laboratory value should the nurse monitor closely?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase is a crucial laboratory value to monitor closely. Elevated levels of serum amylase are a key indicator of pancreatic inflammation and can help confirm the diagnosis of acute pancreatitis. Therefore, monitoring serum amylase levels is essential for assessing the progression and severity of the condition in a client with acute pancreatitis.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.
