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.

Rationale: Middle adulthood is a stage where individuals typically focus on various developmental tasks. Option A is incorrect as middle adults do not necessarily develop an acceptance of diminished strength and increased dependence on others; they often strive to maintain independence. Option B is correct as middle adults are usually focused on improving job performance and advancing their careers. Option C is correct as middle adults tend to welcome opportunities to be creative and productive, engaging in new hobbies or projects. Option D is correct as middle adults often commit to finding friendship and companionship as they value social connections and support networks. Therefore, options B, C, and D are the expected developmental tasks for middle adults, making them the correct choices.

Correct Answer: A

Rationale: Reassessing the client is crucial to identify the reasons for inadequate pain relief. This action allows the nurse to gather more information, evaluate the current pain management interventions, and make necessary adjustments to the care plan. Waiting for the pain to lessen without taking action delays appropriate pain management. Changing the plan of care without reassessment may lead to ineffective interventions. Teaching the client about the plan of care should be based on a reassessment of the current pain relief status to ensure tailored and effective pain management strategies.

Correct Answer: C

Rationale: The correct answer is 'C: Sore throat.' Oxygen toxicity can manifest with symptoms like a sore throat, cough, chest pain, difficulty breathing, and fatigue. However, a sore throat can be an early indicator of oxygen toxicity and should prompt immediate attention. Nasal congestion, cough, and fatigue are not specific indicators of oxygen toxicity but could be related to other factors in a client with COPD receiving oxygen therapy.
