## Question

For each action involving an infusion pump alarm or malfunction, identify whether it supports safe equipment use or is unsafe.

|  | Supports safe equipment use | Unsafe |
| --- | --- | --- |
| Assess the client's perfusion and the infusion immediately when the occlusion alarm sounds. |  |  |
| Silence the alarm and leave transport staff to decide whether the vasoactive medication is still infusing. |  |  |
| Trace the tubing from container to access site and fully correct a clamp, kink, or compression before restarting. |  |  |
| Override the drug-library limit and increase the programmed rate to compensate for the interruption. |  |  |
| Use approved backup equipment to maintain critical therapy, then tag and sequester a pump with an unexplained recurrent alarm. |  |  |
| Restart the same pump repeatedly without verifying the medication, concentration, channel, rate, or alarm cause. |  |  |

## Explanation

An infusion-pump alarm is a safety signal, not an inconvenience to silence. The nurse should assess the client and infusion immediately, trace the tubing from container to client, correct a clearly identified cause, and verify the medication, concentration, rate, and channel before restarting. If the alarm is unexplained or the pump does not function as expected, the nurse should maintain the critical therapy safely with approved backup equipment, remove and tag the suspect pump, and follow reporting procedures. Bypassing limits, repeatedly restarting without resolving the cause, or leaving the client during interrupted vasoactive therapy can produce serious under-infusion or bolus harm.

## In-depth explanation

Correct Answer
Respond to the client first, fully resolve the alarm cause, verify settings, and remove malfunctioning equipment from service.

Why It Fits
A recurrent occlusion alarm during vasoactive therapy coincides with falling blood pressure and may represent interrupted delivery or equipment failure.

Clinical Picture
Infusion-pump failures and programming errors can cause over-infusion, under-infusion, missed treatment, or delayed therapy, especially with high-alert medications.

Memory Link
Alarm means assess, trace, resolve, verify, and replace if unexplained.

NCLEX Rule
Never bypass an alarm or safety limit; protect the client and therapy, follow the device guidance, and sequester equipment that does not perform as expected.

Why the Alternatives Fail
Muting the alarm, forcing flow, or resuming without checking the full system treats the warning rather than the hazard.

## Clinical scenario

Step-down unit
A client receives a high-alert vasoactive medication through a smart infusion pump. During transport, the pump displays a recurrent downstream occlusion alarm, the blood pressure begins to fall, and the tubing appears compressed beneath a side rail. After the tubing is released, the alarm recurs without an obvious cause.

## Key concepts

- **Occlusion alarm** — A pump alert indicating resistance or blockage upstream or downstream that may interrupt fluid delivery.
- **Smart pump** — An infusion device with programmable safety features such as a drug library and dose-limit alerts.
- **Sequester** — Remove suspect equipment from clinical use, label the problem, and hold it for inspection or repair.
