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.

During preoperative teaching for a female client undergoing subtotal thyroidectomy, which statement should the nurse include?
- A. The head of your bed must remain flat for 24 hours after surgery.
- B. You should avoid deep breathing and coughing after surgery.
- C. You won't be able to swallow for the first day or two.
- D. You must avoid hyperextending your neck after surgery.
Correct Answer: D
Rationale: The correct answer is D. Instructing the client to avoid hyperextending the neck after thyroid surgery is crucial to prevent stress on the surgical site and reduce the risk of complications such as strain on the incision or damage to the healing tissues. Choices A, B, and C are incorrect because:
A) Keeping the head of the bed flat for 24 hours is not necessary after a thyroidectomy; elevation of the head of the bed can actually help reduce swelling and improve comfort.
B) Encouraging deep breathing and coughing after surgery is essential to prevent respiratory complications such as pneumonia, so this advice is incorrect.
C) Difficulty swallowing after thyroid surgery is not a typical outcome, so this statement is inaccurate and should not be included in the preoperative teaching.
Which of the following clinical findings would be most concerning in a client with hypothyroidism?
- A. Bradycardia
- B. Dry skin
- C. Constipation
- D. Depression
Correct Answer: A
Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.
A nursing student needs to administer potassium chloride intravenously as prescribed to a client with hypokalemia. The nursing instructor determines that the student is unprepared for this procedure if the student states that which of the following is part of the plan for preparation and administration of the potassium?
- A. Obtaining a controlled IV infusion pump
- B. Monitoring urine output during administration
- C. Diluting an appropriate amount of normal saline
- D. Preparing the medication for bolus administration
Correct Answer: D
Rationale: The correct answer is preparing the medication for bolus administration (Choice D). Potassium should never be administered as a bolus because it can cause cardiac arrest. It must always be diluted and given slowly. Obtaining a controlled IV infusion pump (Choice A) is essential for accurate delivery, monitoring urine output during administration (Choice B) helps assess the client's response, and diluting an appropriate amount of normal saline (Choice C) is necessary to prevent irritation and ensure safe administration.
Which of the following statements is true regarding followership and leadership?
- A. Effective leadership is more important than followership.
- B. Good leaders do not need to be good followers.
- C. A good follower is not just skilled but also self-directed.
- D. Critical thinking is only required for effective leadership.
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.
The client with hypothyroidism is being educated by the healthcare provider about taking levothyroxine. Which of the following instructions should be included?
- A. Take the medication with meals
- B. Take the medication at bedtime
- C. Take the medication on an empty stomach in the morning
- D. Take the medication with a glass of milk
Correct Answer: C
Rationale: The correct answer is to take levothyroxine on an empty stomach in the morning. This instruction is essential to enhance absorption and efficacy of the medication. Taking levothyroxine with meals, at bedtime, or with a glass of milk can interfere with its absorption and effectiveness, leading to suboptimal treatment outcomes.
