Which arm should Charles collect a blood sample? A.Right B.Left C.Either D. Neither 42. What options does Charles have if he is unable to collect a proper venipuncture site?" A. Consider arterial puncture B.Consider capillary puncture C.Repeat the procedure some other time D.Nothing 43. What complication/s might Charles expect? A.Syncope B.Dehydration C.Overweight D.All of the above 44. What must he do to prevent it?* A.Ask the patient to drink water and lie down B.Ask the patient to drink water C.Ask the patient to lie down D.Ask the patient to return some other time Case 2: A phlebotomist name Sarah is in the process of collecting a pro time and CBC from a patient.
