Correct Answer: A

Rationale: Correct Answer: The nurse should first place the side rails in an up position. This action is crucial to prevent the client from falling while the bed is being made. Choice B is incorrect as moving or turning the client is not necessary at this point. Choice C is not a priority when immediate safety concerns are present. Choice D, asking the client if they are comfortable, though important, should come after ensuring the client's safety by raising the side rails.

Correct Answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

Correct Answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, an elevated blood pressure is the most concerning assessment finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention. Increased fatigue may be expected due to anemia associated with CKD and erythropoietin therapy. Low urine output may indicate impaired kidney function but is not as immediately concerning as elevated blood pressure. Elevated hemoglobin levels are the desired outcome of erythropoietin therapy, indicating an appropriate response to treatment.

Correct Answer: B

Rationale: Reorienting the client frequently is the most important nursing intervention in this scenario. It helps reduce confusion and agitation, which are common symptoms of acute delirium in hospitalized elderly clients. Requesting a psychiatric consult (choice A) may be necessary if the reorientation does not improve the client's condition or if there are underlying psychiatric concerns, but reorientation should be attempted first. Administering antipsychotic medications (choice C) should not be the initial intervention as they can have adverse effects in elderly individuals. Obtaining a sitter (choice D) may provide support but does not directly address the client's disorientation and agitation.

Correct Answer: A

Rationale: The correct answer is A: Elevated blood pressure. In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure requires immediate intervention. This finding is concerning as it may indicate worsening hypertension, which can lead to further complications. Increased fatigue (choice B) is common in CKD but may not require immediate intervention unless severe. Headache (choice C) can be a symptom to monitor but does not pose an immediate threat like elevated blood pressure. Elevated hemoglobin (choice D) is actually a desired outcome of erythropoietin therapy and does not require immediate intervention.
