Nursing Elites

1. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

2. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

3. The client has been prescribed metformin (Glucophage) for type 2 diabetes. Which instruction should the nurse include in discharge teaching?

• A. Take the medication at bedtime.
• B. Take the medication with meals.
• C. Take the medication on an empty stomach.
• D. Take the medication as needed for high blood sugar.

Correct answer: B

Rationale: The correct instruction for taking metformin (Glucophage) is with meals. This helps reduce gastrointestinal side effects and improves the medication's absorption. Taking it on an empty stomach can lead to more adverse effects, so it is essential to take it with food. Option A ('Take the medication at bedtime') is incorrect because metformin should be taken with meals to enhance its effectiveness and reduce side effects. Option C ('Take the medication on an empty stomach') is incorrect as taking metformin on an empty stomach can increase the likelihood of experiencing gastrointestinal issues. Option D ('Take the medication as needed for high blood sugar') is incorrect because metformin is typically taken regularly as prescribed, not just as needed for high blood sugar.

4. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?

• A. Asterixis.
• B. Jaundice.
• C. Ascites.
• D. Splenomegaly.

Correct answer: A

Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.

5. The nurse is caring for four clients: Client A, who has emphysema and an oxygen saturation of 94%; Client B, with a postoperative hemoglobin of 8.7 g/dL; Client C, newly admitted with a potassium level of 3.8 mEq/L; and Client D, scheduled for an appendectomy with a white blood cell count of 15,000/mm3. What intervention should the nurse implement?

• A. Increase Client A's oxygen to 4 liters per minute via nasal cannula.
• B. Determine if Client B has two units of packed cells available in the blood bank.
• C. Ask the dietitian to add a banana to Client C's breakfast tray.
• D. Inform Client D that surgery is likely to be delayed until the infection is treated.

Correct answer: D

Rationale: A high white blood cell count, as seen in Client D, indicates infection, which may require postponing surgery to treat the infection adequately. It is crucial to address the underlying infection before proceeding with the appendectomy to prevent complications and ensure a successful surgical outcome.
