Which alarm condition on a smart infusion pump indicates that the upstream occlusion pressure has been exceeded?
Answer: Upstream occlusion alarm
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.
A nurse programs a secondary (piggyback) infusion on a volumetric pump. Which feature automatically resumes the primary infusion when the secondary bag empties?
Answer: Automatic secondary completion
The automatic secondary completion feature detects when the piggyback bag empties and resumes the primary infusion at its programmed rate.
What does the term 'occlusion pressure limit' refer to on an infusion pump?
Answer: The pressure threshold at which the pump alarms for a blockage
The occlusion pressure limit is the configurable pressure threshold at which the pump stops and alarms to alert clinicians of a downstream blockage.
During an infusion, a patient's pump displays a 'soft limit override' alert. What does this indicate?
Answer: A clinician has programmed a dose outside the recommended range but within the hard limit
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.
Which factor most directly affects the accuracy of a syringe pump's delivery rate?
Answer: Correct syringe size and brand recognition by the pump
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.
A nurse notices the infusion pump's flow rate accuracy specification is ±5%. If the pump is set to 100 mL/hr, what is the acceptable delivery range?
Answer: 95–105 mL/hr
A ±5% accuracy specification on a 100 mL/hr setting means the actual delivery can range from 95 to 105 mL/hr and still be within the manufacturer's stated tolerance.
Which action should a nurse take FIRST when an infusion pump repeatedly alarms for air-in-line despite no visible air bubbles?
Answer: Replace the administration set and re-prime
Replacing and re-priming the administration set eliminates micro-bubbles and ensures the air sensor is functioning correctly with a known-good set.
