Safe Medication Administration via Nasogastric Tubes: Key Nursing Practices ...

Question

The nurse is supervising a newly hired nurse administer prescribed medications via a double-lumen nasogastric tube (NGT) with an air vent. Which action by the newly hired nurse requires follow-up? The newly-hired nurse

A. irrigates the air vent before medication administration with water.
B. contacts the pharmacy to obtain available medications in liquid form.
C. flushes the NGT between medications with water.
D. administers each medication separately through the NGT.

CORRECT ANSWER:

A. irrigates the air vent before medication administration with water.

EXPLANATION:

• The air vent of a double-lumen NGT (often called the Salem sump tube) is not meant for irrigation. Its purpose is to prevent the tube from adhering to the stomach lining by allowing continuous airflow. Flushing the air vent with water can lead to malfunction or leakage of gastric contents.

• The other options (B, C, D) reflect correct nursing practices:

  • Using liquid meds when possible reduces tube clogging.

  • Flushing between meds prevents drug interactions and keeps the tube patent.

  • Administering meds separately ensures accurate absorption and monitoring of effects.                                                                                                           FOR EASE OF REMEMBERANCE

Mnemonic: “FLUID”

F – Flush between meds with water

L – Liquid meds preferred to prevent clogging

U – Use separate administration (don’t mix meds together)

I – Irrigate only the tube, NOT the air vent

D – Double-check orders for compatibility and form
