1. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

2. Following a unilateral adrenalectomy, Nurse Betty would assess for hyperkalemia indicated by which of the following signs?

• A. Muscle weakness
• B. Tremors
• C. Diaphoresis
• D. Constipation

Correct answer: A

Rationale: Muscle weakness is a classic manifestation of hyperkalemia, an elevated level of potassium in the blood. After an adrenalectomy, where one adrenal gland is removed, there may be a risk of hyperkalemia due to altered hormone regulation. Tremors (Choice B) are not typically associated with hyperkalemia but may be seen in conditions like hypocalcemia. Diaphoresis (Choice C) and constipation (Choice D) are not specific indicators of hyperkalemia. Diaphoresis is excessive sweating and constipation is a common gastrointestinal issue, neither directly related to potassium imbalances.

3. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

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.

4. A client with diabetes mellitus visits a health care clinic. The client's diabetes was previously well controlled with glyburide (Diabeta), 5 mg PO daily, but recently the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?

• A. Prednisone (Deltasone)
• B. Atenolol (Tenormin)
• C. Phenelzine (Nardil)
• D. Allopurinol (Zyloprim)

Correct answer: A

Rationale: Prednisone, a corticosteroid, can increase blood glucose levels by promoting gluconeogenesis and decreasing glucose uptake by cells. This medication can lead to hyperglycemia in patients, especially those with diabetes mellitus. Atenolol (Tenormin) is a beta-blocker and is not known to significantly affect blood glucose levels. Phenelzine (Nardil) is a monoamine oxidase inhibitor used to treat depression and anxiety disorders; it does not typically impact blood glucose levels. Allopurinol (Zyloprim) is a xanthine oxidase inhibitor used to manage gout and does not interfere with blood glucose regulation.

5. To be effective, a nurse manager needs both managerial and leadership skills. Interpersonal activities have many concerns that overlap both leaders and managers. However, some interpersonal activities are needed by nurse managers, but are not specific duties of leaders. Which of the following is an interpersonal activity of nurse managers, but not necessarily all nurse leaders?

• A. Coaching
• B. Resource allocation
• C. Planning for the future
• D. Monitoring

Correct answer: B

Rationale: Resource allocation is an interpersonal activity specific to nurse managers because it involves managing the distribution of resources within the healthcare environment, which is not necessarily a duty for all leaders. While coaching, planning for the future, and monitoring are important skills for both leaders and managers, resource allocation is a task that is more specific to the managerial role of nurse managers.
