| 19. A standing order of platelets was shipped to your facility by your supplier. It was inadvertently left in the
| | | | | | | | | | | | | | | | | | |
corner of the department until discovered 36 hours later. What would the appropriate action be for the blood
| | | | | | | | | | | | | | | | | |
banker? |
a. If the temperature in the box was 22 +/- 2°C and the platelet swirl seemed OK, it would be OK
