## Question

After transfer, a client has IV, enteral-feeding, oxygen, and urinary tubing. The nurse is about to connect a medication syringe to an unlabeled port. Which action should the nurse take first?

## Option

1. Choose the port that is closest to the medication pump.
2. Ask the client which tubing was used on the previous unit.
3. Trace the tubing from the client to its source and verify the intended route before connecting. **✔ Correct answer**
4. Connect the syringe briefly and stop if the client reports discomfort.

**Correct answer: 3**

## Explanation

The FDA recommends tracing every tube or catheter from the patient to its point of origin before connecting a new device or infusion.

## In-depth explanation

Quick answer
Perform line reconciliation by tracing the tubing end to end before connection.

Why this is correct
Look-alike small-bore connectors can permit wrong-route delivery. FDA safety guidance recommends tracing the tube from the patient to the source during handoff and before making a connection.

Easy analogy or mental picture
Follow the railroad track to both endpoints before putting a train on it.

Memory hook
Trace before you connect.

NCLEX decision rule
When the route is uncertain, stop and verify the physical pathway; proximity, color, or memory is not enough.

Why the other choices are wrong
The nearest port may be the wrong system, the client may not know, and a trial connection can cause immediate serious harm.References

## Clinical scenario

Line reconciliation
Identify every tube at the patient and source, label it, verify the prescribed route, and resolve uncertainty before connection.
