1. 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.

2. Which of the following clinical findings would be most concerning in a client with hypothyroidism?

• A. Bradycardia
• B. Dry skin
• C. Constipation
• D. Depression

Correct answer: A

Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.

3. A client with diabetes mellitus is receiving an oral antidiabetic medication. The nurse should monitor for which of the following adverse effects?

• A. Weight gain
• B. Hypoglycemia
• C. Hyperglycemia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client with diabetes mellitus is taking oral antidiabetic medication, the nurse should closely monitor for hypoglycemia, which is a common adverse effect. Hypoglycemia occurs when the blood sugar levels drop below normal range, leading to symptoms like confusion, shakiness, and sweating. Weight gain (Choice A) is not a typical adverse effect of oral antidiabetic medications. Hyperglycemia (Choice C) is the opposite of the desired effect of antidiabetic medications, which aim to lower blood sugar levels. Bradycardia (Choice D) is not directly associated with oral antidiabetic medications; it refers to a slow heart rate.

4. For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?

• A. They contain exudate and provide a moist wound environment.
• B. They protect the wound from mechanical trauma and promote healing.
• C. They debride the wound and promote healing by secondary intention.
• D. They prevent the entrance of microorganisms and minimize wound discomfort.

Correct answer: C

Rationale: Wet-to-dry dressings are utilized in this case to debride the wound by removing dead tissue and promoting healing by secondary intention. Choice A is incorrect as wet-to-dry dressings do not provide a moist wound environment; instead, they promote drying to aid in debridement. Choice B is incorrect because their primary purpose is not to protect the wound but to remove dead tissue. Choice D is incorrect as the main function of wet-to-dry dressings is not to prevent the entrance of microorganisms or minimize wound discomfort.

5. The client with DM is being taught by the nurse about the importance of monitoring blood glucose levels. The nurse should instruct the client to:

• A. Check blood glucose only when feeling unwell.
• B. Check blood glucose before meals and at bedtime.
• C. Check blood glucose only after meals.
• D. Check blood glucose only in the morning.

Correct answer: B

Rationale: The correct answer is to check blood glucose before meals and at bedtime. Monitoring blood glucose levels before meals allows the client to adjust their insulin or oral antidiabetic medications based on their current levels. Checking at bedtime helps in ensuring blood glucose levels are at a safe range throughout the night. Option A is incorrect because blood glucose should be monitored regularly as part of diabetes management, not just when feeling unwell. Option C is incorrect because checking only after meals does not provide a complete picture of blood glucose control throughout the day. Option D is incorrect as checking only in the morning does not cover the full spectrum of blood glucose variations that can occur during the day.
