The healthcare provider prescribes penicillin 800,000 units intramuscularly (IM) for a patient with a streptococcal infection. The vial available is labeled Penicillin 50,000 units/mL. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.).
