Answer 1

0.408 gram for 180-lb patient

Answer 2

Answer: 0.408 grams is to given for 180 lb patient.

Explanation:

Given : A intramuscular medication is given at 5.00 mg/kg of body weight.

That is for a body with weight of 1 kg , we have to give 5.00 mg of medication

Converting the mass in kg to pounds

1 kg = 2.20462 lb

Thus for a body with weight of 2.20462 lb , we have to give= 5.00 mg of medication

For body weight of 180 lb , we have to give =
`(5.00)/(2.20462)* 180=408.23mg` of medication

Also 1 mg = 0.001 grams

Thus
`408.23mg=(0.001)/(1)* 408.23=0.408grams`

Thus for a body with weight of 2.20462 lb , we have to give 0.408 grams of medication.
