Correct Answer: A

Rationale: Ethics is the correct answer because it specifically deals with the study of conduct and character. Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. While justice and morals are related to ethical considerations, they do not directly represent the study of conduct and character. Non-maleficence is a principle in medical ethics related to avoiding harm.

Correct Answer: D

Rationale: When a client expresses the desire to discontinue dialysis, the most appropriate response is to seek clarification and establish understanding. This approach allows the healthcare provider to comprehend the client's concerns, provide support, and engage in a collaborative decision-making process. Choice A, asking the client why they want to discontinue, can be perceived as confrontational and may not effectively address the underlying reasons. Instructing the client to focus on self-care (Choice B) may overlook the client's autonomy and decision-making capacity. Offering to call the provider to cancel dialysis (Choice C) does not actively involve the client in the decision-making process or address their concerns adequately.

Correct Answer: A

Rationale: The correct answer is A: Increase in frequency of swallowing. After rhinoplasty, an increase in frequency of swallowing may indicate possible bleeding, which requires immediate action by the nurse. The client could be experiencing postoperative bleeding, and prompt intervention is necessary to prevent complications. Choice B, moderate sanguineous drainage on the drip pad, is expected in the immediate postoperative period and does not require immediate action unless it becomes excessive. Choice C, bruising to the face, is a common postoperative finding and does not require immediate action unless it is excessive or affects the airway. Choice D, absent gag reflex, would not be expected immediately following rhinoplasty and would require intervention, but the manifestation of increased swallowing frequency is a higher priority due to its association with potential bleeding.

Correct Answer: B

Rationale: The correct answer is B because hair loss is a common adverse effect of chemotherapy. Options A, C, and D are incorrect. Avoiding drinking water before meals, experiencing an increase in appetite, or expecting appetite to increase are not related to the potential adverse effects of chemotherapy.

Correct Answer: B

Rationale: The best strategy to promote independence in self-care for a client concerned about extreme fatigue after an acute myocardial infarction is to instruct the client to gradually resume self-care tasks, with rest periods. This approach allows the client to regain independence without overexerting. Choice A is incorrect because encouraging the client to rest completely and letting the healthcare team take over self-care tasks may hinder independence. Choice C is incorrect as assigning assistive personnel to complete self-care tasks does not promote the client's independence. Choice D is not the best option as the primary focus should be on empowering the client to perform self-care tasks independently.
