Correct Answer: D

Rationale: The correct answer is D: Non-maleficence. Non-maleficence refers to the ethical principle of avoiding harm. In this scenario, the nurse questions the medication prescription to prevent potential harm to the client, demonstrating the principle of non-maleficence. Choice A, fidelity, pertains to being faithful and keeping promises, which is not the focus of the scenario. Choice B, autonomy, relates to respecting a client's right to make decisions about their care, not the nurse's actions. Choice C, justice, involves fairness and equal treatment, which is not directly applicable to the nurse questioning a medication prescription to prevent harm.

Correct Answer: B

Rationale: The correct action for the nurse to take when noticing a discrepancy between the client's current IV infusion and the information received during the shift report is to compare the current infusion with the prescription in the client's medication record. This step is crucial to ensure the accuracy of the prescribed treatment and to prevent any potential harm to the client. Option A is incorrect because completing an incident report should only be done after verifying the discrepancy. Option C is incorrect as contacting the charge nurse should come after confirming the details. Option D is incorrect as submitting a written warning is not appropriate without verifying the information first.

Correct Answer: D

Rationale: In resolving ethical dilemmas, it is essential to identify possible solutions to address the client care dilemma effectively. Option A, 'Ensure client autonomy only,' is not comprehensive enough to resolve complex ethical issues. Option B, 'Consider only medical benefits,' overlooks other important factors beyond medical benefits that are involved in ethical decision-making. Option C, 'Ensure clear communication among the health care team,' is important but may not be sufficient on its own to resolve the ethical dilemma. Therefore, the most effective strategy among the given options is to identify possible solutions to navigate through the ethical dilemma.

Correct Answer: C

Rationale: Dry skin is a common manifestation of hypothyroidism due to decreased thyroid hormone levels, leading to reduced sweating and oil production. Weight gain may occur due to a slowed metabolism, not diarrhea, as hypothyroidism is more commonly associated with constipation. Hair loss is typically associated with hyperthyroidism, not hypothyroidism.

Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.
