A nurse questions a medication prescription as too extreme in light of the client's advanced age and unstable status. The nurse understands that this action is an example of which of the following ethical principles?

Correct Answer: D

Rationale: The correct answer is D, Nonmaleficence. Nonmaleficence refers to the principle of 'do no harm.' In this scenario, questioning a potentially harmful prescription for a client with advanced age and unstable status aligns with the principle of nonmaleficence, as the nurse is advocating for the client's safety and well-being. Choice A, Fidelity, refers to being faithful and keeping promises, which is not directly related to the situation described. Choice B, Autonomy, pertains to respecting a patient's right to make their own decisions, which is not the focus of the nurse questioning the prescription. Choice C, Justice, involves fairness and equal treatment, which is not the primary ethical principle at play in this situation.

Correct Answer: B

Rationale: The most significant factor in planning dietary changes for a client with cardiovascular disease is the involvement of the client in planning the change. By involving the client in the planning process, the nurse ensures that the client takes ownership of their health and is more likely to adhere to and succeed in modifying dietary habits. This empowerment and engagement enhance the client's motivation and commitment to making sustainable changes. Financial resources, availability of low-sodium foods, and frequency of dietary counseling sessions are important considerations but are not as crucial as the client's active involvement in the planning process.

Correct Answer: A

Rationale: In paralytic ileus, bowel sounds are typically absent or significantly reduced due to decreased motility of the intestines. This absence of bowel sounds is a key characteristic used in diagnosing paralytic ileus. Hyperactive bowel sounds are not expected in this condition as there is a lack of normal peristalsis. Normal bowel sounds would not be present in paralytic ileus, and hypoactive bowel sounds, which indicate decreased bowel motility, are more commonly associated with conditions like postoperative ileus or constipation, rather than paralytic ileus.

Correct Answer: A

Rationale: The correct approach when measuring a client's blood pressure, especially for a client with hypertension, is to obtain the blood pressure under the same conditions each time. Consistency in measurement conditions helps ensure accurate and comparable blood pressure readings. Using a different arm for each measurement (Choice B) is not ideal as it can lead to variations in readings. Measuring the blood pressure while the client is standing (Choice C) is not the standard practice and may not provide accurate results. Taking multiple readings at different times of the day (Choice D) may be useful for monitoring blood pressure trends but is not the priority when ensuring accurate individual readings.

Correct Answer: A

Rationale: The correct answer is A. When a healthcare provider witnesses a client signing an informed consent form for surgery, they are affirming that the signature on the form belongs to the client. This is crucial for ensuring patient autonomy and informed decision-making. Choices B, C, and D are incorrect because while it is important for the client to understand the risks of surgery, be aware of postoperative care instructions, and have an opportunity to ask questions, these elements are not specifically affirmed by the healthcare provider witnessing the signature.
