The licensed prescriber orders 60 mg of prednisone po twice a day for a patient who weighs 30 kg. It is available as 15 mg/5 mL. Recommended dosage is 0.5 to 2 mg/kg/24 h given in one or two doses. Maximum dose is 80 mg/24 h
Is this a safe and therapeutic dose?
No
Yes
The Correct Answer is B
Patient's prescribed dose: 60 mg × 2 = 120 mg/24 hr
Maximum recommended dose: 80 mg/24 hr
Patient's weight: 30 kg
Recommended dosage range:
0.5 mg/kg × 30 kg = 15 mg/day
2 mg/kg × 30 kg = 60 mg/day
The prescribed 120 mg/day exceeds both the maximum safe dose of 80 mg/day and the therapeutic range for this patient (15–60 mg/day).
Therefore, the dose is not safe.
