CRNI CRNI Infusion Pump Technology and Safety Practice Test 4

Question 1

Which alarm condition on a smart infusion pump indicates that the upstream occlusion pressure has been exceeded?

Accepted Answer

Upstream occlusion alarm

Answer

An upstream occlusion alarm fires when resistance proximal to the pump exceeds the set threshold, indicating a blockage between the fluid source and the pump mechanism.

Question 2

A nurse programs a secondary (piggyback) infusion on a volumetric pump. Which feature automatically resumes the primary infusion when the secondary bag empties?

Accepted Answer

Automatic secondary completion

Answer

The automatic secondary completion feature detects when the piggyback bag empties and resumes the primary infusion at its programmed rate.

Question 3

What does the term 'occlusion pressure limit' refer to on an infusion pump?

Accepted Answer

The pressure threshold at which the pump alarms for a blockage

Answer

The occlusion pressure limit is the configurable pressure threshold at which the pump stops and alarms to alert clinicians of a downstream blockage.

Question 4

During an infusion, a patient's pump displays a 'soft limit override' alert. What does this indicate?

Accepted Answer

A clinician has programmed a dose outside the recommended range but within the hard limit

Answer

A soft limit override means the nurse acknowledged and bypassed the advisory warning but stayed within the hard (absolute) safety limit programmed in the drug library.

Question 5

Which factor most directly affects the accuracy of a syringe pump's delivery rate?

Accepted Answer

Correct syringe size and brand recognition by the pump

Answer

Syringe pumps calculate flow based on the syringe's inner diameter; selecting the wrong syringe size or brand causes the pump to miscalculate volume per step, leading to dosing errors.
