Question 1

What is an enteric tube and what are its main purposes?

Accepted Answer

An enteric tube is inserted through a nostril or other route into the stomach or intestines. It serves multiple purposes including stomach decompression by removing air, gastric contents, and secretions; providing enteric feeding; and administering medications or oral contrast. Enteric tubes are indicated for patients with impaired swallowing, neurological conditions increasing aspiration risk, or inability to maintain adequate oral intake of fluids or calories.

Question 2

Why is verifying enteric tube placement important before administering medications?

Accepted Answer

Enteric tubes are initially positioned and verified by X-ray, but gastric peristalsis can cause tubes to migrate from their intended termination location. Confirming appropriate tube location before administering medications ensures the drug reaches the correct gastrointestinal site, preventing medication delivery errors and potential patient harm.

Question 3

What forms must oral medications take when administered through an enteric tube?

Accepted Answer

Medications administered through an enteric tube must be oral preparations converted into appropriate forms. The nurse may crush medications into powder, or the pharmacy may prepare them as suspensions or liquid formulations. Prior to crushing, nurses must confirm it is safe to do so, as crushing extended-release medications can cause toxic levels.

Question 4

What risks are associated with crushing medications for enteric tube administration?

Accepted Answer

Crushing extended-release medications can lead to toxic medication levels in the patient. Additionally, crushing medications with cytotoxic or carcinogenic properties can harm the healthcare worker administering them. Nurses must verify medication safety before crushing and follow appropriate precautions to protect themselves and patients.

Question 5

How does tube lumen size affect medication administration through enteric tubes?

Accepted Answer

Smaller-bore enteric tubes are more prone to clogging if medications are not prepared properly or are not flushed with adequate fluid. Proper medication preparation and appropriate flushing volumes are essential to prevent tube obstruction and ensure successful drug delivery through narrow-lumen tubes.

Question 6

What are the different types of enteric tubes based on insertion site?

Accepted Answer

Enteric tubes are named according to their insertion site and gastrointestinal termination point. A nasogastric tube, one common type, is inserted through a nostril and passed along the upper gastrointestinal tract into the stomach. Other tube types vary based on where they are inserted and where they terminate in the digestive system.

Question 7

How does medication administration through enteric tubes compare to other routes?

Accepted Answer

Enteric tube medication administration differs from other routes like preparing and administering oral tablet and liquid medications because tube medications must be specially prepared as powders, suspensions, or liquids. This route is used for patients unable to swallow safely or maintain adequate oral intake, requiring careful tube placement verification and appropriate medication formulation.
