The directive 'Within thirty minutes' applies to which step?

• A. After receiving the blood, it must be hung within 30 minutes.
• B. Time to flush IV line before transfusion.
• C. Time to call for assistance.
• D. Time to order more blood.

Answer: (A)

The important timing refers to starting the transfusion promptly after the blood product is received from the blood bank. You should hang the unit within 30 minutes of its arrival because this keeps the blood at the proper temperature and ensures it’s used while it’s viable. Delaying beyond 30 minutes increases the risk of issues with the product and may require returning the unit to the blood bank. The other actions—making sure the IV line is flushed, calling for help, or ordering more blood—are important steps in transfusion care, but they aren’t governed by this 30‑minute rule.
