Answer 1

1.available dose=25mg/kg

Weight of the child=77 lbs=(77*0.45)kg=34.65 kg

Desired dose=(available dose* body weight)=25*34.65=866.25 mg=866 mg

2.available dose=50mg/ml

Desired dose=​​​​​12.5mg

Let 'x' ml contains 12.5 mg of diphenhydramine.

Ie; The desired amount=(12.5mg/50mg)*1ml=0.25 ml

3.available dose=400mg/5ml

Desired dose=80mg/kg/day

Body weight=10 kg

Desired dose for the child with 10 kg body weight=(80*10)mg/day=800mg/day

Let 'x' ml contacts 800mg of the drug.

Ie;. 400mg/5ml=800 mg/x ml

The desired amount=(800*5)/400=10ml

4.available dose=4mg/2ml

Desired dose=0.15mg/kg

Desired dose for the client with body weight of 29.4 kg=0.15*29.4=4.41 mg

Let 'x' ml contains 4.41 mg of ondansetron.

Ie; 4.41mg/'x' ml=4mg/2ml

The desired amount,'x' ml=(4.41*2)/4=2.205=2.2ml
