Correct Answer: B

Rationale: The correct answer is B because it provides a specific action (offering water) at regular intervals (every 2 hours) to promote hydration, which is a clear and measurable nursing intervention. Choice A is too prescriptive and lacks flexibility. Choice C is reactive and not proactive. Choice D is vague and lacks specific guidance on how to achieve the desired outcome. By offering water consistently, the nurse ensures proactive care and helps meet the client's hydration needs effectively.

Correct Answer: D

Rationale: The correct answer is D because antimetabolites interfere with the synthesis of nucleic acids (RNA and/or DNA), affecting multiple stages of RNA and DNA synthesis. This disruption hinders cell division and leads to cell death. Choices A and B are incorrect because antimetabolites do not specifically target cell division during the M phase or normal cellular processes during the S phase. Choice C is also incorrect because antimetabolites primarily target nucleic acid synthesis rather than altering the chemical structure of DNA or the binding between DNA molecules.

Correct Answer: A

Rationale: The correct answer is A because nosocomial pneumonia occurs in a healthcare setting, such as hospitals or long-term care facilities, where patients are at increased risk due to exposure to pathogens and weakened immune systems. Choice B is incorrect as the timeframe of onset is not limited to within 48 hours of admission. Choice C is incorrect as nosocomial pneumonia can occur in both immunocompromised and immunocompetent hosts. Choice D is incorrect as it refers to pneumonia acquired outside of a healthcare setting.

Correct Answer: D

Rationale: The correct answer is D: Refer the client to the American Cancer Society’s Reach for Recovery program or another support program. This choice is the best option as it provides the client with additional support and resources specifically tailored to individuals coping with cancer and mastectomy. The Reach for Recovery program offers emotional support, education, and practical assistance which can immensely benefit the client during this challenging time. A: Involving the client's spouse or partner is important, but support programs like Reach for Recovery can offer specialized assistance that may not be fully covered by the spouse's support alone. B: While proceeding with the next phase of treatment is important, emotional support and coping mechanisms are equally crucial, which support programs can provide. C: Asking the client to remain cheerful may put pressure on her and may not address her emotional needs adequately, unlike a support program that is designed to provide comprehensive support.

Correct Answer: C

Rationale: The correct answer is C because it accurately defines a transient ischemic attack (TIA) as a temporary interruption in blood flow to the brain. This response demonstrates the nurse's knowledge and ability to provide accurate information to the family member. Option A is incorrect because it deflects the question to the doctor without providing any information. Option B is incorrect because it inaccurately states that TIA causes permanent brain damage, which is not true. Option D is also incorrect because it simply restates the abbreviation without providing any explanation of what TIA actually means.
