Answer 1

10 answer:

desired strength is 750 mcg ; 1 mcg =1000mg

what we have is 1 gram/ ml ; 1 gram =1000mg

so using the formula desired strength(D)/ on hand (H) * Quantity.

750000 mg/1000 mg*1 ml = 750 mg/ ml.

but we want in mcg so divide 750 mg by 1000 (divide mass by 1000 to get in mcg) so 750/1000=0.75 that is approximately equivalent to 0.8 ml

11 answer

desired strength of meperidine =100 mg which has to be given 4 hourly that means 6 times a day.

what we have on hand is 50 mg/ 5 ml oral solution ( 10 mg / ml) then we have to give 10 ml 4 hourly to gt desired strength .

D/H *Q ; 100/10*1 =10 ml.

if we have 50 mg of meperidine then 2 tablets to be given 4 hourly that means 6 times a day.
