What should a nurse do after confirming correct tube placement for medication administration via an NGT connected to suction?

Administer the medication immediately.
Flush the tube with water.
Disconnect the suction for 30 minutes.
Document the procedure in the record.

The correct answer is: Flush the tube with water.

Flushing the tube with water after confirming correct tube placement is essential for several reasons. First, it ensures that the medication can flow freely through the tube and reduces the risk of clogging. Additionally, flushing helps to ensure that the medication is properly diluted and can be absorbed effectively once administered. This step is crucial in maintaining tube patency and optimizing the therapeutic effect of the medication, as any residual formula or suction effects could otherwise interfere with the medication's action. Moreover, flushing the tube with water allows for the medication to be properly delivered into the patient's gastrointestinal tract without obstruction. In this context, while it is important to proceed with the medication administration in a timely manner, ensuring the tube is adequately flushed is a priority that supports the overall goal of safely delivering medications.
