Final answer:
In the event of a seizure during venipuncture, stop the procedure, ensure the patient's safety, call for help, and wait for medical personnel to arrive.
Step-by-step explanation:
If a patient has a seizure while you are performing a venipuncture, the correct course of action is: 1) Stop the venipuncture and ensure the patient's safety. Prioritize the patient's well-being by removing any sharp objects, including the needle, and cushion their head if possible. Clear the area of any furniture or equipment that could cause injury. Next, call for help and wait for medical assistance. Do not try to restrain the patient or put anything in their mouth. Monitor the patient's vital signs and seizure duration while waiting for professional medical help. It is essential to document the incident thoroughly once the situation is under control.
