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. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

3. A patient with cirrhosis of the liver and ascites is scheduled for a paracentesis. What should the nurse do to prepare the patient for the procedure?

• A. Have the patient void immediately before the procedure.
• B. Position the patient upright or semi-Fowler's in bed.
• C. Administer a full liquid diet.
• D. Encourage the patient to ambulate for 30 minutes.

Correct answer: A

Rationale: The correct preparation for a paracentesis in a patient with cirrhosis and ascites includes having the patient void immediately before the procedure. This is important to reduce the risk of bladder puncture during the paracentesis. Positioning for a paracentesis is typically upright or semi-Fowler's, not flat in bed. Administering a full liquid diet or encouraging ambulation for 30 minutes are not directly related to preparing a patient for a paracentesis procedure.

4. A client with type 1 diabetes mellitus is experiencing nausea and vomiting. What advice should the nurse give regarding insulin administration?

• A. Skip your insulin dose until you can eat.
• B. Take your insulin as prescribed, but monitor your blood glucose closely.
• C. Reduce your insulin dose by half.
• D. Only take your long-acting insulin.

Correct answer: B

Rationale: The correct advice for a client with type 1 diabetes mellitus experiencing nausea and vomiting is to take insulin as prescribed but monitor blood glucose closely. It is essential to continue insulin therapy even if not eating normally to prevent complications from high blood sugar levels. Skipping insulin doses can lead to dangerous fluctuations in blood glucose levels. Reducing the insulin dose without proper guidance can also result in uncontrolled blood sugar. Taking only long-acting insulin may not provide adequate coverage for mealtime blood sugar elevation. Therefore, the best course of action is to take prescribed insulin doses while closely monitoring blood glucose levels.

5. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

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

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.
