Answer 1

Ans) 22) Ordered Aminophylline IV infusion= 0.3 mg/kg/hr

Weight= 45kg

45×0.3 = 13.5 mg dise per hour

Available dose: 500 mg/250ml

500 mg= 250 ml

13.5 mg = x

x= 250 × 13.5 /500 = 6.75 ml

Infusion will be required at the rate of 6.75ml/he

22) Appropriate equivalent:

1) 30.73 mg

Explaination:

1 mg = 1000 mcg

30.73 mg = x

x= 30730 mcgs

2) 30 ml

Explaination:

1 l = 1000 ml

x= 30 ml

x= 30/1000 = 0.03 l

3) 25 ml

Explaination:

1 tsp = 5ml

x= 25 ml

x= 25/5= 5 tsp

4) 480 grams

Explaination:

1 kg = 1000 grams

x = 480 grams

x = 480/1000 = 0.48 kg
