Answer 1

1. Available 0.4mg per 1ml Vail

1÷0.4x0.02=0.05ml

0.02mg = 0.05 ml

So nurse draw 0.05ml from the Vail.

3 . Available ivermectin tablet s in 3 mg

Administer ivermectin 125mcg/kg

Adult weight = 132lbs

1mcg = 0.001mg

125mcg = 0.12mg

1 lbs= 0.453

132lbs = 59.87kg

Per kg = 0.12mg of ivermectin

59.87 kg body wt = 7 mg for single dose

4. Theophylline gives 7mg/kg

Weight is 39lbs

39lbs = 17.69 kg

Per1kg 7mg of dose given

For 17.69kg ?

7÷1x17.69= 123.8mg
