Question

1. If a Tagamet 300mg / 150ml is administered intravenously at a rate of 25mg per hour. How
much will have been administered in mg and ml after 7 hours.
The maximum daily dose of APAP allowed for an adult is 3g. They can be administered at
frequencies of 6 to 8 hours. If a child who is 6 years old were to take acetaminophen for fever
every 6 hours, what would the corresponding mg dose be?
For a 35 year old adult the average dose of Augmentin is 875mg every 12 hours. What will the
daily dose be for a child weighing 44lbs?

The dose of dexamethasone for children is 0.08mg-0.3mg / kg / day divided into 6 or 12 hour
intervals. For an infant who weighs 17lbs, calculate:

a.Day dose (maximum and minimum)
b. Dose at 6 hour intervals
c. Dose at 12 hour intervals

Answer 1

•ANSWER•1

Given value ,

Tagamet 300mg/ 150 ml

Rate of infusion- 25 mg per hour

To find- infused solution in 7 hour in mm or mg

Solution,

tagamet - 300 mg/ 150 ml

= 2 mg / ml

formula

Rate of infusion= total volume/ Time

so, put the value

Total volume= rate of infusion× time

Total volume= 25 × 7

Total volume= 175 ml

total 175 ml volume infused in 7 hour (answer)

while, tagamet 300 mg / 150 ml

So, 2 mg/ ml

= 2× 175 ml = 350 mg volume infused in 7 hour

answer- 350 mg to be infused in 7 hour

•ANSWER•2

Given value

daily dose of APAP= 3 gram for adult

Frequency= 6 per hour

To find,

dose of acetamenofen to who is 6 year old

Young Formula

child dose= {age( in year)/age(in year) +12 }×adult dose

So, chlid dise={ 6 / 6 +12}×3 gram

={ 6/ 18}×3

={ 1/3}× 3

= 3/ 3

  = 1 gram

So,   = 1000 mg per day

While frequency= 6 houry

So, dose per 6 hour= 1000/ 4

= 250 mg per 6 hour

= 250 mg per 6 hour (answer)

•ANSWER•3

given value,

875 mg per 12 hour

Child weight- 44 lb

formula,

Clark's formula

Child dose= {Body weight(lb) / 150}× adult dose

Child dose= {44 /150}× 875 mg

=( 44/ 150)× 875

=0.2933× 875

=256.666

= 256.67 mg per 12 hour

= 256.67 mg per 12 hour ( answer)
