The healthcare provider prescribes streptomycin 200 mg intramusculary every 12 hours. The vial is labeled, 'Streptomycin 1 gram/2.5 mL'. How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct answer
A
Rationale
Calculation: 1 gram = 1000 mg; vial is 1000 mg/2.5 mL. Proportion: (200 mg / 1000 mg) x 2.5 mL = 0.5 mL.
