Correct Answer: D

Rationale: The most appropriate intervention for a postoperative male client with diabetes mellitus who reports impotence and concerns about its impact on his marriage is to suggest referral to a sex counselor or other appropriate professional. Impotence can have significant emotional and relational effects, and a sex counselor is specifically trained to address such concerns. Encouraging the client to ask questions about personal sexuality (Choice A) may not provide the specialized support needed in this situation. Providing time for privacy (Choice B) is important but may not directly address the client's concerns about impotence. Providing support for the spouse or significant other (Choice C) is valuable but may not be as effective as seeking professional help to address the client's specific issue of impotence.

Correct Answer: C

Rationale: The correct answer is to increase physical activity to help control blood glucose levels. Physical activity is essential in managing type 2 diabetes mellitus as it helps improve insulin sensitivity, control weight, and regulate blood sugar levels. Avoiding all forms of physical exercise (Choice A) is incorrect as exercise plays a crucial role in diabetes management. While limiting carbohydrate intake (Choice B) can be beneficial, setting a strict limit of less than 30 grams per day is too restrictive and may not be suitable for everyone. Consuming a high-protein, low-fat diet (Choice D) is generally a healthy choice, but it is not the primary lifestyle modification recommended for managing type 2 diabetes mellitus.

Correct Answer: D

Rationale: Pheochromocytoma is a tumor of the adrenal medulla that secretes excessive catecholamines, leading to symptoms such as hypertension. The normal blood pressure range is around 120/80 mm Hg, so a blood pressure reading of 176/88 mm Hg is most likely to be detected in a client with pheochromocytoma. Choices A, B, and C are incorrect because pheochromocytoma typically presents with hypertension, not a normal or low blood pressure (choice A), not related to blood glucose levels (choice B), and not bradycardia (choice C).

Correct Answer: C

Rationale: The scenario described with hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area is indicative of myxedema coma, a severe and life-threatening complication of hypothyroidism. Myxedema coma requires immediate emergency treatment to prevent further deterioration. Choice A, thyroid storm, is a complication of hyperthyroidism characterized by an increase in body temperature, heart rate, and blood pressure. Choice B, cretinism, refers to untreated congenital hypothyroidism leading to mental and physical growth retardation. Choice D, Hashimoto's thyroiditis, is an autoimmune condition leading to hypothyroidism but does not present with the acute, life-threatening symptoms described in the scenario.

Correct Answer: A

Rationale: The correct answer is to monitor blood glucose levels before meals and at bedtime. This timing allows for a comprehensive understanding of how the body responds to food intake and to assess fasting glucose levels. Monitoring blood glucose only after meals (Choice B) may miss important pre-meal fluctuations. Checking glucose levels only in the morning (Choice C) overlooks the impact of meals throughout the day. Monitoring blood glucose only when feeling unwell (Choice D) is reactive and does not provide consistent data for managing diabetes effectively. Therefore, monitoring blood glucose before meals and at bedtime helps in maintaining good glucose control and preventing complications.
