you’re a phlebotomist working in a hospital. your first draw of the day is an elderly woman in the cardiac intensive care unit. as you greet the patient, she states that she had a heart attack 2 days ago and is on a blood thinner. you observe an iv in place on her right forearm. while reading the requisition for tests, you see that her doctor is ordering a complete metabolic panel (cmp), a cbc and differential, and coagulation studies (pt/ptt).
