Step-by-step explanation:
The proper action to take when a patient does not have a wristband on but there is one attached to their IV stand is to verify the patient's identity with the wristband on the IV stand. This is important to ensure that the blood sample collected belongs to the correct patient. It is not recommended to draw blood until the nurse has attached a wristband, write 'Unable to draw' on the requisition form, or ask the patient to confirm their identity.
