Correct Answer: C

Rationale: The correct answer is to monitor blood glucose before meals and at bedtime. This timing allows the client to assess fasting levels and make informed decisions about mealtime insulin or medication doses. Monitoring only when feeling unwell (choice A) is not sufficient for proper glucose management as it may miss important trends. Monitoring only before meals (choice B) is helpful but does not provide a complete picture of the client's glucose control throughout the day. Monitoring only after meals (choice D) is less beneficial than monitoring before meals as it does not capture fasting levels. Therefore, monitoring before meals and at bedtime (choice C) is the most comprehensive approach to maintain good glucose control and prevent complications.

Correct Answer: C

Rationale: The correct answer is C: 'A good follower is not just skilled but also self-directed.' This statement is true as being self-directed complements effective leadership. Good followers possess the ability to take initiative, work independently, and contribute positively to a team without constant supervision. Option A is incorrect because followership is equally important as leadership in achieving group success. Option B is incorrect as good leaders often demonstrate qualities of good followership, such as being able to listen, collaborate, and support others. Option D is incorrect because critical thinking is essential for both effective leadership and followership, not exclusively for leadership roles.

Correct Answer: C

Rationale: The correct answer is C. In a psychological contract between staff members and nurse managers, staff members are expected to fulfill the requests of managers, and in return, they are rewarded with assignments, promotions, and evaluations. This reciprocal relationship forms the basis of the psychological contract. Choices A, B, and D are incorrect because they do not accurately capture the essence of the psychological contract. While nurse managers may provide positive evaluations, coordinate departments, supervise staff, advocate for staff, and support nursing roles, these actions alone do not define the specific reciprocal nature of the psychological contract outlined in choice C.

Correct Answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

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.
