Answer to Question 1

ANS:
1

The correct calculation is:

88 lb/2.2 kg = 40 kg

Dose of DDAVP is 0.05 mg/kg/day divided bid

0.05 mg  40 = 2 mg/day

2 mg/2 = 1 mg for one dose

Answer to Question 2

ANS:
105

The correct calculation is:

66 lb/2.2 kg = 30 kg

Dose of PTU is 7 mg/kg/day divided every 12 hours

7 mg  30 = 210 mg

210 mg/2 = 105 mg
