Which of the following populations is eligible for Medicare?

A. Democratic is incorrect. A democratic leadership style involves collaboration and input from team members in decision-making. In this scenario, the nurse manager is directing staff to follow a new procedure without seeking their input, which is not indicative of a democratic approach.
B. Authoritative is correct. An authoritative leadership style is characterized by clear direction and decision-making from the leader. The nurse manager in this scenario is changing the policy and directing the staff to follow the new procedure, which reflects an authoritative approach.
C. Trait theory is incorrect. Trait theory focuses on the personal qualities and characteristics of leaders, such as confidence or decisiveness, rather than a specific leadership approach or style.
D. Laissez-faire is incorrect. A laissez-faire leadership style is hands-off and allows team members to make decisions independently, which is the opposite of what the nurse manager is doing in this situation.

A. Hypernatremia and hypertension is incorrect. In panhypopituitarism, adrenal insufficiency from decreased ACTH results in hyponatremia and hypotension, not hypernatremia and hypertension.
B. Hypotension and tachycardia is correct. Due to decreased ACTH, there is reduced cortisol and aldosterone, leading to low blood pressure and compensatory tachycardia.
C. Increased bone density due to decreases in growth hormone is incorrect. Growth hormone deficiency actually results in decreased bone density, not increased. GH plays a critical role in bone growth and maintenance.
D. Hypoglycemia due to decreased ACTH and cortisol is correct. Without sufficient cortisol, glucose regulation is impaired, increasing the risk of hypoglycemia.
E. Decreased ability to cope with stress secondary to decreased cortisol is correct. Cortisol is essential for the stress response, and its deficiency leads to poor tolerance to physical and emotional stress.
F. Hyperkalemia secondary to decreased aldosterone is correct. Low ACTH leads to adrenal insufficiency, which can reduce aldosterone production, causing sodium loss and potassium retention (hyperkalemia).
