Multiple Choice

Which PRBC scenario would prompt returning the unit to inventory?

The key idea is how long a PRBC unit has been outside its controlled cold environment and what temperature it reached. Red cells must be kept at 1–6°C in storage. If a unit leaves controlled storage, it can be returned to inventory only if its temperature stays within an acceptable range (typically not above 10°C) and the time it was out is within the allowed window (usually 30 minutes or less). In this scenario, the unit was outside the lab for 30 minutes and its temperature remained at 9°C, which stays below the 10°C ceiling and does not exceed the time limit. That makes it eligible to be returned to inventory. The other options involve a unit that has been used (crossmatched and transfused) or shows a compromised condition (leakage), which means they should not be returned, and a unit described as simply stored at 4°C for 15 minutes doesn’t clearly indicate an out-of-cooler excursion requiring return.
