Final answer:
When drawing blood from a patient with severe Down's syndrome, a phlebotomist should explain the procedure in simple terms, consult with the patient's guardian for informed consent, and, if needed, have the guardian assist in holding the patient's arm still.
Step-by-step explanation:
When a phlebotomist has a requisition to draw blood on a patient with severe Down's syndrome, the following steps should be considered:
- Explain the procedure to the patient in simple terms, and observe for any sign of understanding or consent, proceeding only if appropriate.
- It's essential to speak with the patient's guardian before performing the venipuncture to ensure that consent is informed and the explanation is understood, considering the patient’s condition and ability to understand.
- Only draw the patient's blood without trying to explain the procedure if the patient is explicitly unable to comprehend and the guardian provides consent.
- Request the patient's guardian to assist in holding the patient's arm still for the procedure if necessary and appropriate to ensure the patient's safety and comfort.
It is important to approach the situation with sensitivity and respect for the patient's needs and abilities.
