Correct Answer: B

Rationale: Following a transsphenoidal hypophysectomy, it is crucial to avoid activities such as coughing, sneezing, and blowing the nose to prevent an increase in intracranial pressure or the risk of cerebrospinal fluid leakage. Coughing, sneezing, or nose blowing can strain the surgical site, potentially leading to complications. Lying flat for 24 hours is not typically required after this surgery. Fluid intake should be encouraged to prevent dehydration. Ringing in the ears is not a common complication associated with this type of surgery.

Correct Answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

Correct Answer: A

Rationale: In a client with diabetes mellitus (DM) taking insulin, the development of fever and confusion may indicate hyperglycemia or diabetic ketoacidosis. Checking the blood glucose level is the priority action in this situation. This will help determine if the symptoms are related to high blood sugar levels, guiding further interventions. Administering a fever-reducing medication (choice B) addresses only the symptom of fever and does not address the underlying cause. Providing fluids to drink (choice C) is important but should come after addressing the potential hyperglycemia or diabetic ketoacidosis. Notifying the health care provider (choice D) can be important, but immediate action to evaluate and manage the client's condition should precede contacting the provider.

Correct Answer: C

Rationale: Exercising at least five times a week is recommended to meet the goals of planned exercise for diabetic clients. This frequency helps in managing blood sugar levels effectively and improving overall health. Exercising once a week (Choice A) may not provide sufficient benefits or consistency required for diabetic clients. Exercising three times a week (Choice B) is better but may still fall short of the recommended frequency for optimal outcomes. Exercising every day (Choice D) may lead to burnout or overtraining if not properly balanced with rest days, which could be counterproductive for diabetic clients.

Correct Answer: B

Rationale: The correct answer is B. Clients with type 2 diabetes mellitus should not stop taking their medication even if blood sugar levels are normal. This is because ongoing management is necessary to control blood sugar levels and prevent complications. Choice A is correct as rotating injection sites helps prevent skin damage and improves insulin absorption. Choice C is correct as regular monitoring of blood sugar levels is vital for managing diabetes effectively. Choice D is correct as following a healthy diet and exercising regularly are key components of diabetes management.
