48. A medical assistant works under the supervision of a physician or a licensed nurse.
A medical assistant can assist the nurse or physician in their work and follow their orders.
A medical assistant cannot start or stop an IV neither can he administer drugs into IV line. This is beyond the practice scope of a medical assistant. Therefore option (c) is wrong.
