Correct Answer: D

Rationale: Option D is the best response as it allows the client to express her specific concerns, providing the nurse with valuable assessment data. This open-ended question encourages the client to share her worries and feelings, which can guide the nurse in addressing her unique needs. Options A and B make assumptions about the client's concerns based on her weight, potentially invalidating her feelings and inhibiting effective communication. Option C is premature as understanding the client's concerns should precede discussions about the frequency of sexual intercourse, which may not address the core issues the client is facing.

Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to inform the surgeon that the operative permit is not signed and that the client has questions about the surgery. It is the responsibility of the surgeon to explain the procedure to the client and obtain the client's signature on the permit. While the nurse can witness the client's signature on the permit, the procedure must first be explained by the healthcare provider or surgeon, including addressing the client's questions. Therefore, informing the surgeon is the priority to ensure proper communication and consent before the surgery. Answering the client's questions about the surgery (Choice B) may not provide accurate information and could lead to misunderstanding. Reassuring the client (Choice D) is important, but obtaining proper consent and addressing concerns should come first. Witnessing the client's signature (Choice A) is not sufficient if the client has unanswered questions and the permit is not signed.

Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.

Correct Answer: D

Rationale: When a postoperative client's respiratory rate increases, it is essential to determine the underlying cause. Pain, anxiety, and fluid accumulation in the lungs can lead to tachypnea (increased respiratory rate). Therefore, the priority intervention is to assess if pain is the contributing factor. Encouraging increased ambulation may worsen oxygen desaturation in a client with a rising respiratory rate. Offering a high-carbohydrate snack is not indicated as it can increase carbon metabolism; instead, consider providing an alternative energy source like Pulmocare liquid supplement. Forcing fluids may exacerbate respiratory congestion in a client with a compromised cardiopulmonary system, potentially leading to fluid overload. Therefore, determining the role of pain in tachypnea is crucial for appropriate management.

Correct Answer: C

Rationale: The E in the acronym DELIRIUM stands for Electrolytes. Electrolyte imbalances can lead to delirium. The other letters in the acronym represent: D = Dementia; L = Lung, liver, heart, kidney, brain; I = Infection; R = Rx Drugs; I = Injury, Pain, Stress; U = Unfamiliar environment; M = Metabolic. It is crucial to differentiate delirium from dementia, as delirium is often reversible with treatment of underlying causes. Dementia should only be considered after ruling out delirium, as addressing the contributing factors may alleviate the delirium state.
