Answer 1

1) Dose by Young's rule (mg/day) = Adult Dose in mg/day x [Age / (Age+12)]

15× 8÷(8+12)

15 × 0.4= 6mg

3) 3 ×18÷(18+12)

3×0.6= 1.8g

4) wt of child in kg = 20 kg

Dose will b 20 × 60 = 1200 This is given in divided doses

5) for children we use micro drip set which has drop factor of 60

Rate =total volm÷ time in mints × drop factor

= 2000÷300×60

= 6.6× 60

6) dose = 10 × 6 ÷(6+12)

= 10× 0.3

= 3.3mg

INSULIN

1) 25 units are to b administered 3 times a day

Before breakfast, before lunch, at bed time

2) 45units administered subcutaneously after meal
