Which of the following is true about nursing ethics?

Correct Answer: B

Rationale: The correct answer is B. Nursing ethics primarily focus on the moral character of nurses, emphasizing principles, values, and virtues that guide their professional conduct. Choice A is incorrect as nursing ethics are more about individual moral decision-making than organizational practices. Choice C is incorrect because while nurses consider patients' experiences and needs, nursing ethics primarily revolve around the nurses themselves. Choice D is incorrect as nursing ethics are centered on the moral obligations and responsibilities of nurses, not specifically on the ethical principles governing healthcare organizations.

Correct Answer: B

Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of heart disease and stroke. Uncontrolled blood glucose levels in clients with diabetes mellitus (DM) can lead to cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, increasing the risk of atherosclerosis and cardiovascular events. Choices B, C, and D are incorrect because uncontrolled blood glucose levels do not improve wound healing, reduce the need for medication, or decrease the risk of infection. In fact, uncontrolled blood glucose levels can impair wound healing, require more medications to manage symptoms, and increase the risk of infections due to compromised immune function.

Correct Answer: D

Rationale: The correct answer is to advise the client to avoid using sharp instruments to trim the toenails. This is crucial because using sharp instruments can lead to injuries such as cuts or wounds, increasing the risk of infections, especially in clients with diabetes who have decreased sensation in their feet. Choice A is incorrect because tight shoes can restrict circulation and increase the risk of pressure sores. Choice B is incorrect because applying lotion between the toes can create a moist environment, leading to fungal infections. Choice C is incorrect because using a heating pad can lead to burns, which can go unnoticed due to decreased sensation in diabetic feet.

Correct Answer: B

Rationale: The correct answer is B: Decisional activities. A nurse manager conducting evaluations and reviewing staffing needs for the future involves making decisions related to resource allocation, planning, and problem-solving. These activities fall under the category of decisional activities in management. Choice A, Interpersonal activities, would involve activities like communicating, motivating, and leading staff. Choice C, Informational activities, would involve activities like gathering and disseminating information. Choice D, Transformational activities, would involve inspiring and motivating staff to achieve organizational goals through vision and change.

Correct Answer: B

Rationale: Postoperative hypotension is a common complication after adrenal tumor removal in a client with Cushing's syndrome. This occurs due to the sudden withdrawal of cortisol, which leads to a relative adrenal insufficiency state. Hyperglycemia (Choice A) is more common preoperatively due to excessive cortisol levels. Hypokalemia (Choice C) and Hyponatremia (Choice D) are also associated with Cushing's syndrome but are less likely to be immediate postoperative complications compared to hypotension.

Correct Answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.

Correct Answer: C

Rationale: The correct answer is C. Nurses advocate for patients by ensuring that they receive the necessary care and by protecting their rights. This involves speaking up for patients, ensuring they are treated with respect, and helping them access appropriate healthcare services. Option A, providing information for informed decision-making, is an important aspect of nursing care but not the central role of advocacy. Option B, communicating patients' needs to the healthcare team, is essential but more focused on teamwork and collaboration. Option D, helping patients navigate the healthcare system and access resources, is valuable but not the primary definition of advocacy in nursing.

Correct Answer: A

Rationale: Chvostek's and Trousseau's signs are clinical manifestations that suggest hypocalcemia, a common complication following thyroidectomy. Chvostek's sign is elicited by tapping the facial nerve, resulting in facial muscle contraction, while Trousseau's sign is provoked by inflating a blood pressure cuff, leading to carpal spasm. Both signs are indicative of low calcium levels in the blood. Therefore, options B, C, and D are incorrect as they do not correlate with the signs specifically associated with hypocalcemia.
