Nursing Elites

1. The nurse is caring for a client with myxedema coma. Which of the following interventions should the nurse prioritize?

• A. Administer intravenous fluids
• B. Provide a warming blanket
• C. Administer levothyroxine intravenously
• D. Place the client in Trendelenburg position

Correct answer: C

Rationale: In myxedema coma, the priority intervention is to administer levothyroxine intravenously. Myxedema coma is a severe form of hypothyroidism, and intravenous levothyroxine is crucial to rapidly replace deficient thyroid hormones. Administering intravenous fluids (choice A) may be necessary, but levothyroxine takes precedence. Providing a warming blanket (choice B) can help maintain the client's body temperature, but it does not address the underlying thyroid hormone deficiency. Placing the client in Trendelenburg position (choice D) is not indicated and can potentially worsen the client's condition.

2. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor for which of the following potential side effects?

• A. Hypoglycemia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hyponatremia

Correct answer: C

Rationale: The correct answer is C, Hyperglycemia. Corticosteroid therapy can lead to hyperglycemia by increasing blood glucose levels. Corticosteroids can induce insulin resistance, decrease glucose uptake by tissues, and promote gluconeogenesis. While corticosteroid therapy can cause hypoglycemia in some cases, it is more commonly associated with hyperglycemia. Hyperkalemia (choice B) is more commonly associated with conditions like renal failure or certain medications. Hyponatremia (choice D) is typically not a common side effect of corticosteroid therapy unless there are other contributing factors present.

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. A client with type 2 DM is being treated with metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?

• A. Take the medication with meals.
• B. Take the medication on an empty stomach.
• C. Take the medication before bedtime.
• D. Avoid taking the medication if you miss a meal.

Correct answer: A

Rationale: The correct instruction for a client taking metformin (Glucophage) is to take the medication with meals. This helps reduce gastrointestinal side effects and improves absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of side effects. Choice C is incorrect as there is no specific recommendation to take metformin before bedtime. Choice D is incorrect as missing a meal should not lead to avoiding the medication, but the client should take it with the next meal as prescribed.

5. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.
