Answer #1

Safe single dose is 3.75mg/kg q6h

The patient weight is 66 pounds.

1 pound = 0.454 kg

66 pound= 29.964 kg (approx. 30kg)

So the patient weight is 30 kg.

Safe single dose for this patient is =30 x 3.75= 112.5 mg q6h

But the patient is getting 125mg q6h is greater than safe dose

The patient is not in safe dose
