After ensuring correct tube placement for an NGT connected to suction, which action should the nurse take next?

After confirming the correct placement of a nasogastric (NG) tube that is connected to suction, it is important to flush the tube with water. This action helps ensure that the tube is patent, which means it is open and unobstructed. Flushing the tube can also help clear any residual contents from the tube that could prevent proper functioning. Additionally, it prepares the tube for any upcoming medications or feeds that may need to be administered, maintaining a clear pathway for these substances to pass through. Flushing with water is a common practice to promote hygiene and prevent potential clogging.

The other actions may not be immediately necessary following the confirmation of placement. Clamping the tube may interrupt suction and could lead to a buildup of gastric contents if the patient is not being adequately drained. Administering medications before ensuring the tube is adequately flushed might lead to complications if the tube is not patent. Crushing tablets may not be appropriate as certain medications are not meant to be altered in form, and this depends on the medication prescribed. Ensuring the tube is flushed properly sets a basis for the safe administration of any treatment as outlined in patient care protocols.
