Choice A rationale:

Verifying the patient's identification is an essential step in patient safety, but it alone does not ensure transfusion safety.

Transfusion safety involves multiple steps beyond identification.

Choice B rationale:

Maintaining aseptic technique and infection control practices is crucial during a blood transfusion.

This includes using sterile equipment, wearing gloves, and following proper hand hygiene.

Infection can be a severe complication of transfusion if proper precautions are not taken.

Choice C rationale:

Administering blood products using old and sterile equipment is not a safe practice.

Blood transfusions require the use of fresh, sterile equipment to prevent contamination and ensure patient safety.

Choice D rationale:

Monitoring the patient's condition only after the transfusion is not sufficient to ensure safety.

Continuous monitoring during the transfusion is necessary to detect and respond to any adverse reactions promptly.
