A nurse is caring for a client who is dying of metastatic breast cancer. She has a prescription for an opioid pain medication PRN. The nurse is concerned that administering a dose of pain medication might hasten the client's death. Which of the following ethical principles should the nurse use to support the decision not to administer the medication?

Correct Answer: B

Rationale: The correct answer is B: Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to do no harm to the patient. In this scenario, the nurse's primary concern should be to alleviate the client's pain and suffering, as withholding pain medication would go against the principle of nonmaleficence. Administering the medication is in the client's best interest to provide comfort and maintain dignity in the end-of-life care. Summary: A: Utilitarianism focuses on the greatest good for the greatest number of people, which may conflict with the individual patient's well-being. C: Fidelity pertains to keeping promises and being faithful to commitments, which is not directly relevant to the ethical dilemma presented. D: Veracity refers to truth-telling and honesty, which is important but not the primary ethical principle to consider in this situation.

Correct Answer: B

Rationale: The correct answer is B because relapsing fever is characterized by recurrent episodes of fever followed by periods of normal temperature. This pattern of fever, normal, fever, normal repeats over time. Choice A describes a pattern of consistently alternating fever and normal days, which is not characteristic of relapsing fever. Choice C and D do not provide any relevant information to describe the pattern of relapsing fever.

Correct Answer: B

Rationale: Step 1: Feet together reduces stability and increases risk of falling. Step 2: Carrying object with feet together restricts balance and proper weight distribution. Step 3: Feet apart provides a wider base, enhancing stability and reducing strain on the body. Summary: Option B is correct as it promotes proper body mechanics by ensuring a wider base of support. Choices A, C, and D are incorrect as they do not address the importance of base support and can lead to increased risk of injury.

Correct Answer: B

Rationale: The correct answer is B (30 minutes) because of the refractory period that occurs in men after ejaculation. During this time, men typically experience a decrease in sexual arousal and are unable to achieve another erection or ejaculation immediately. This refractory period lasts around 30 minutes on average, although it can vary among individuals. Choice A (None) is incorrect because it does not align with the physiological refractory period that occurs after ejaculation. Choice C (Anytime at will) is incorrect as it implies that men can immediately engage in sexual activity again after ejaculation, which is not typically the case due to the refractory period. Choice D is incomplete, so it cannot be considered as a valid option.

Correct Answer: B

Rationale: The correct answer is B: Take bp while sleeping. This is because blood pressure should ideally be measured during sleep to get an accurate reading unaffected by external factors such as stress or physical activity. Choice A is incorrect because past blood pressure readings may not reflect the current status. Choices C and D are incomplete and do not offer a viable alternative method for measuring blood pressure.
