Blood products should not be left at room temperature for more than how long before administration?

• A. 2 hours
• B. 15 minutes
• C. 4 hours
• D. 30 minutes

Answer: (D)

Blood products are kept cold to preserve their quality, but once they’re brought to the bedside, they should be started promptly to minimize bacterial growth and deterioration. The maximum time allowed before you begin the transfusion is 30 minutes after the unit is removed from refrigeration. If you can’t start within that window, you should return the unit to the blood bank and obtain a new one. After you begin, the transfusion as a whole should be completed within about 4 hours. So, the 30-minute window is the correct preadministration limit. Options suggesting longer times aren’t aligned with this initial window, and 4 hours reflects the total infusion time, not how long the unit can sit at room temperature before starting.
