Correct Answer: A

Rationale: The correct answer is A because severe pain can hinder the client's ability to participate effectively in learning. Pain can be distracting and may prevent the client from focusing on acquiring new information or skills. Choice B is incorrect because asking for a demonstration shows an interest in learning and readiness to understand the exercises. Choice C is incorrect as inquiring about potential complications indicates the client's engagement in understanding the procedure and its outcomes, demonstrating readiness to learn. Choice D is incorrect as agreeing to the procedure does not necessarily reflect a lack of readiness to learn. The client may still be open to receiving information about postoperative care, indicating a level of readiness to learn despite agreeing to the surgery.

Correct Answer: C

Rationale: Comparing the client's wristband with the medication administration record is a crucial step in ensuring medication safety. The wristband typically contains unique identifiers such as the client's name, date of birth, and medical record number, which should be cross-checked with the medication administration record to confirm the correct patient. Asking the client to state their name (Choice A) or date of birth (Choice B) may not be as reliable as the information can be misunderstood or miscommunicated. Asking for the room number (Choice D) is not a reliable client identifier for medication administration and does not confirm the patient's identity accurately.

Correct Answer: B

Rationale: The correct answer is B, a lactating woman nursing her 3-day-old infant. During lactation, women have increased nutritional needs, including protein, to support milk production for their infants. Protein is essential for proper growth and development. While choice A, a college-age track runner with a sprained ankle, may require protein for tissue repair, the lactating woman's need is greater due to the demands of breastfeeding. Choice C, a school-aged child with Type 2 diabetes, may have specific dietary considerations related to diabetes management but does not necessarily require additional protein intake compared to a lactating woman. Choice D, an elderly man being treated for a peptic ulcer, may need protein for wound healing, but the nutritional need for a lactating woman is higher to support her infant's growth.

Correct Answer: B

Rationale: The most appropriate initial nursing action when a client develops a rash and itching while receiving intravenous antibiotics is to discontinue the antibiotic infusion. This is crucial to prevent further allergic reactions. Administering diphenhydramine (Benadryl) (Choice A) can be considered after discontinuing the antibiotic infusion. Applying a cool compress to the rash (Choice C) may provide symptomatic relief but does not address the underlying cause. Notifying the healthcare provider (Choice D) is important but should come after discontinuing the antibiotic infusion to ensure the client's safety.

Correct Answer: A

Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
