How often must ambient air temperature be recorded for platelets stored on a rotator set?

Platelets that are stored on a rotator set must have their ambient air temperature monitored closely due to the need for maintaining specific storage conditions that ensure their viability and function. The correct answer indicates that temperature must be recorded every 4 hours.

This frequent monitoring is crucial because platelets stored in this manner are sensitive to temperature fluctuations. Maintaining an appropriate temperature helps prevent adverse effects on platelet quality, functionality, and overall patient safety. Ensuring that the environment remains within an acceptable range can significantly impact the shelf life and effectiveness of transfusions.

Other options suggest less frequent monitoring, which could lead to undetected deviations from the required temperature range. This could compromise the quality of the platelets, increasing the risk of transfusion-related complications for patients relying on these blood products.
