Correct Answer: B

Rationale: When assessing a client with a newly applied cast, the nurse should expect a capillary refill of approximately 2 seconds, as this indicates adequate circulation. A capillary refill longer than 3 seconds suggests impaired circulation, which is abnormal. Therefore, a capillary refill of 5 seconds is the finding the nurse should expect. Pitting edema and shortness of breath are not typically directly related to a newly applied cast and should not be expected findings in this scenario.

Correct Answer: B

Rationale: Increasing dietary fiber is an effective recommendation for clients experiencing constipation as it helps promote regular bowel movements. Choice A, increasing fluid intake, is also important but the most appropriate initial recommendation for constipation is to increase dietary fiber. Choice C, administering a laxative, should not be the first-line recommendation and is typically considered after dietary and lifestyle interventions. Choice D, encouraging bed rest, does not directly address constipation relief or prevention.

Correct Answer: A

Rationale: In acute renal failure, it is crucial to monitor urine output to assess kidney function and fluid balance. Administering diuretics helps manage fluid levels by promoting urine production. Choice B is incorrect because administering IV fluids can worsen fluid overload in renal failure patients, and restricting potassium intake is not typically the initial approach. Choice C is not the primary intervention but is important for long-term management. Choice D is incorrect as administering potassium can be dangerous in renal failure, and restricting fluids can lead to dehydration.

Correct Answer: C

Rationale: The correct answer is C: Agitation and assaultiveness. Risperidone is commonly prescribed for clients with Alzheimer's disease to reduce symptoms of agitation and aggressive behavior. This medication helps in managing challenging behaviors often seen in individuals with Alzheimer's. Choice A, sleep disturbances, is incorrect as risperidone is not primarily indicated for treating sleep issues in Alzheimer's patients. Choice B, concomitant depression, is also incorrect as risperidone is not the first-line treatment for depression in Alzheimer's disease. Choice D, confusion and withdrawal, is incorrect as risperidone does not directly target these symptoms in Alzheimer's patients.

Correct Answer: A

Rationale: When managing care for a patient with a wound infection, administering prescribed antibiotics is crucial. Antibiotics are necessary to treat the infection and prevent it from worsening. While cleaning the wound with saline and applying a sterile dressing are important components of wound care, the primary treatment for a wound infection is antibiotics. Monitoring for signs of sepsis is also essential, but administering antibiotics promptly is the most critical step in managing a wound infection.
