Correct Answer: B

Rationale: The correct answer is to put bed rails up on the side of the bed opposite from the nurse. This action is essential to prevent the client from falling out of bed during the turning process. Since the nurse can only stand on one side of the bed, having the bed rails up on the opposite side provides an additional safety measure. Securing the client's arm and leg or lowering the head of the bed would not prevent the client from falling and may pose a risk of injury. Using a turn sheet correctly can be helpful, but ensuring the bed rails are up is a more direct safety measure in this situation.

Correct Answer: C

Rationale: To collect a wound culture, the nurse should first clean the wound to remove skin flora and then insert a sterile swab from a culturette tube into the wound secretions.

Correct Answer: B

Rationale: The healthcare provider should first retake the blood pressure in the right arm, deflating the cuff slowly, because a low systolic and high diastolic blood pressure measurement is often the result of deflating the cuff too rapidly. Taking the BP in the same arm ensures consistency and accuracy of the measurement.

Correct Answer: C

Rationale: To ensure accurate creatinine clearance results, it is crucial to collect all urine within the 24-hour period. The process should begin with discarding the first specimen and then collecting all subsequent urine in the designated 24-hour collection container. This ensures that the sample is complete and accurate for the creatinine clearance calculation.

Correct Answer: D

Rationale: The correct answer is D because emptying a urinary catheter drainage bag exposes the nurse to body fluids, necessitating the use of barrier gloves as per Standard Precautions to prevent potential infection transmission.
