Nursing Elites

1. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:

• A. Increase thyroid hormone production
• B. Decrease thyroid hormone production
• C. Relieve symptoms such as tachycardia and anxiety
• D. Prevent weight loss

Correct answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

2. Dr. Kennedy prescribes glipizide (Glucotrol), an oral antidiabetic agent, for a male client with type 2 diabetes mellitus who has been having trouble controlling the blood glucose level through diet and exercise. Which medication instruction should the nurse provide?

• A. Be sure to take glipizide 30 minutes before meals.
• B. Glipizide may cause a low serum sodium level, so make sure you have your sodium level checked monthly.
• C. You won't need to check your blood glucose level after you start taking glipizide.
• D. Take glipizide after a meal to prevent heartburn.

Correct answer: A

Rationale: Glipizide should be taken 30 minutes before meals to maximize its glucose-lowering effect.

3. A client with Addison's disease is being educated about managing the condition during times of stress. The nurse should instruct the client to:

• A. Double the dose of corticosteroids during periods of stress.
• B. Skip the dose of corticosteroids if you feel well.
• C. Decrease fluid intake to prevent hypertension.
• D. Avoid physical activity during stressful times.

Correct answer: A

Rationale: Clients with Addison's disease should be educated to double their corticosteroid dosage during periods of stress. This is crucial to prevent adrenal crisis, as stress can increase the body's demand for cortisol. Skipping doses when feeling well can lead to an adrenal crisis if stress occurs suddenly. Decreasing fluid intake can exacerbate dehydration and electrolyte imbalances, which are already concerns in Addison's disease. Avoiding physical activity during stressful times is not the most appropriate advice; moderate physical activity can be beneficial, as long as the client is adequately managing their corticosteroid regimen.

4. The client has been vomiting and has had numerous episodes of diarrhea. Which laboratory test should the nurse monitor?

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

Correct answer: C

Rationale: During episodes of vomiting and diarrhea, there is a risk of significant potassium loss, leading to potential electrolyte imbalances. Monitoring serum potassium levels is crucial in this situation to assess and manage any abnormalities promptly. Serum calcium (Choice A) is not typically affected by vomiting and diarrhea. Serum phosphorus (Choice B) levels are not commonly altered by these symptoms. Serum sodium (Choice D) may be affected in severe cases of dehydration, but potassium monitoring is a higher priority due to its potential for rapid depletion in vomiting and diarrhea.

5. A client with syndrome of inappropriate antidiuretic hormone (SIADH) is at risk for which of the following complications?

• A. Hypernatremia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is B: Hyponatremia. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention in the body. This causes dilutional hyponatremia, where the sodium levels in the blood become abnormally low. Option A, Hypernatremia, is incorrect because SIADH does not cause elevated sodium levels. Option C, Hyperkalemia, is incorrect as SIADH does not directly affect potassium levels. Option D, Hypercalcemia, is also incorrect as SIADH does not impact calcium levels.
