1. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

2. What is the primary cause of jaundice in a client with liver cirrhosis?

• A. Decreased bile production
• B. Increased bilirubin levels
• C. Hepatic inflammation
• D. Portal hypertension

Correct answer: B

Rationale: Jaundice in a client with liver cirrhosis is primarily caused by increased bilirubin levels. In liver cirrhosis, impaired liver function leads to the accumulation of bilirubin in the blood, resulting in jaundice. Bilirubin is a yellow pigment produced from the breakdown of red blood cells, and its elevation is a common manifestation of liver dysfunction. Choices A, C, and D are incorrect. While decreased bile production can contribute to jaundice, in liver cirrhosis, the key factor is the buildup of bilirubin due to liver dysfunction, not a decrease in bile production. Hepatic inflammation and portal hypertension are associated with liver cirrhosis but are not the primary causes of jaundice in this context.

3. A client with newly diagnosed diabetes mellitus is being discharged home. Which statement indicates the client understands the instructions about managing blood glucose levels?

• A. I will test my blood glucose level once a week.
• B. I should eat a snack if my blood glucose is 70 mg/dl.
• C. If I feel shaky, I should take another dose of insulin.
• D. It's okay to skip a meal if I'm not hungry.

Correct answer: B

Rationale: Choice B is the correct answer. Eating a snack when blood glucose is low (70 mg/dl) can help prevent hypoglycemia. It is important for clients with diabetes to manage their blood glucose levels to prevent complications, and consuming a snack when glucose levels drop can help maintain the balance.

4. A 60-year-old woman presents with pruritus, jaundice, and xanthomas. Laboratory tests reveal elevated cholesterol and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: The combination of pruritus, jaundice, and xanthomas, along with elevated cholesterol and alkaline phosphatase levels, is classic for primary biliary cirrhosis. Pruritus is often the initial symptom, followed by jaundice due to cholestasis. Xanthomas, elevated cholesterol, and alkaline phosphatase levels are also common findings in primary biliary cirrhosis. Primary sclerosing cholangitis and pancreatic cancer may present with similar symptoms but are less likely in this clinical context.

5. A client with heart failure is prescribed digoxin (Lanoxin). Which instruction should the nurse include in the client's teaching plan?

• A. Take your pulse before each dose and hold the medication if your pulse is below 60 beats per minute.
• B. Increase your intake of foods high in potassium.
• C. Take the medication with a high-fiber meal to enhance absorption.
• D. Skip a dose if you feel dizzy or lightheaded.

Correct answer: A

Rationale: The correct instruction for a client prescribed digoxin is to take their pulse before each dose and hold the medication if the pulse is below 60 beats per minute. This is crucial to prevent digoxin toxicity, as digoxin can cause adverse effects when the pulse rate is too low. Monitoring the pulse regularly ensures safety and appropriate management of the medication.
