A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:
- A. Increase thyroid hormone production
- B. Decrease thyroid hormone production
- C. Relieve symptoms such as tachycardia and anxiety
- D. Prevent weight loss
Correct Answer: C
Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

A female client with physical findings suggestive of a hyperpituitary condition undergoes an extensive diagnostic workup. Test results reveal a pituitary tumor, necessitating a transsphenoidal hypophysectomy. The evening before the surgery, Nurse Jacob reviews preoperative and postoperative instructions provided to the client earlier. Which postoperative instruction should the nurse emphasize?
- A. You must lie flat for 24 hours after surgery.
- B. You must avoid coughing, sneezing, and blowing your nose.
- C. You must restrict your fluid intake.
- D. You must report ringing in your ears immediately.
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.
During a class on exercise for diabetic clients, a female client asks the nurse educator how often to exercise. The nurse educator advises the clients to exercise how often to meet the goals of planned exercise?
- A. At least once a week
- B. At least three times a week
- C. At least five times a week
- D. Every day
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.
The healthcare provider is caring for a client with pheochromocytoma. Which of the following interventions should the healthcare provider implement?
- A. Administer beta-blockers to control blood pressure
- B. Encourage a high-sodium diet
- C. Monitor for signs of hyperglycemia
- D. Restrict fluid intake to prevent edema
Correct Answer: A
Rationale: The correct intervention for a client with pheochromocytoma is to administer beta-blockers to control blood pressure. Pheochromocytoma is a catecholamine-secreting tumor that can cause severe hypertension. Beta-blockers are used to block the effects of catecholamines and help control blood pressure in these clients. Encouraging a high-sodium diet (Choice B) would not be appropriate as it can worsen hypertension. Monitoring for signs of hyperglycemia (Choice C) is not directly related to managing pheochromocytoma. Restricting fluid intake (Choice D) may lead to dehydration and is not a recommended intervention for this condition.
A healthcare professional is focusing on improving the ability to multitask without losing focus and to turn problems into opportunities. Which of the following leadership theories describes the professional's focus?
- A. Emotional intelligence
- B. Motivation theory
- C. Situational leadership theory
- D. Transformational leadership theory
Correct Answer: B
Rationale: Motivation theory explains that individuals act based on what they want to achieve, focusing on goals and desires. In this scenario, the healthcare professional's emphasis on improving multitasking skills and problem-solving aligns with the essence of motivation theory. Emotional intelligence primarily pertains to understanding and managing emotions, not specifically related to multitasking and problem-solving. Situational leadership theory emphasizes adapting leadership styles based on the situation and followers, not directly related to individual focus improvement. Transformational leadership theory focuses on inspiring and motivating followers to achieve common goals rather than individual task management and problem-solving skills.
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.
