- B. Asystole may be associated
- C. There is increased risk of epilepsy in adults

Trauma can be a precipitating factor but the most relevant option is asystole.
The healthcare provider prescribes epoetin alfa (Procrit) 8,200 units subcutaneously for a client with chronic kidney disease (CKD). The 2 ml multidose vial is labeled, 'Each 1 ml of solution contains 10,000 units of epoetin alfa.' How many ml should the nurse administer?
