Rationale: Flushing the feeding tube every 4 hours is essential to maintain patency and prevent clogging, ensuring the client receives the prescribed enteral nutrition without interruption. Monitoring intake and output, measuring temperature, and changing the feeding bag and tubing are also important aspects of care but not directly related to maintaining the patency of the feeding tube in a client receiving continuous enteral feedings.

Rationale: Tuberculosis is transmitted through the air, making it an airborne disease. Airborne precautions are essential to prevent the spread of tuberculosis to others. These precautions include placing the client in a negative pressure room, wearing an N95 respirator mask, and ensuring proper ventilation to minimize the risk of transmission to healthcare workers and other clients.

Correct Answer: D

Rationale: Flushing the NG tube with water before and after administering medications is essential to prevent clogging of the tube and ensure proper delivery of medication. This practice helps maintain tube patency and decreases the risk of obstruction, which could compromise the client's treatment and nutrition. By flushing the tube, the healthcare provider ensures that the medication is completely delivered and that there are no residual drug particles left in the tube, which could lead to blockages or inconsistent dosing. Therefore, flushing the NG tube is a crucial step in the safe administration of medications to clients receiving enteral feedings.
