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: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

Correct Answer: C

Rationale: The correct first action when a client with DM is experiencing symptoms of hypoglycemia is to check the client's blood glucose level. This step is crucial to confirm hypoglycemia before initiating any treatment. Giving the client orange juice (Choice A) is a common intervention for treating hypoglycemia, but it should not be done before confirming the blood glucose level. Administering insulin (Choice B) is not appropriate for hypoglycemia as it would further decrease the blood glucose levels. Notifying the healthcare provider (Choice D) can be important, but the immediate priority is to assess the blood glucose level to guide treatment.

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.

Correct Answer: A

Rationale: Clients with Cushing's syndrome are at risk for hyperglycemia due to the effects of cortisol on glucose metabolism. Monitoring blood glucose levels is crucial to detect and manage hyperglycemia promptly. Restricting fluid intake (choice B) is not necessary unless specifically indicated for another condition, as clients with Cushing's syndrome are prone to fluid imbalances. Administering potassium supplements (choice C) is not appropriate as clients with Cushing's syndrome often have elevated potassium levels due to the effects of cortisol. Encouraging a high-protein diet (choice D) is not recommended as clients with Cushing's syndrome should focus on a balanced diet to manage their condition effectively.
