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 =\(\frac{5.00}{2.20462}\times 180=408.23mg\) of medication
Also 1 mg = 0.001 grams
Thus \(408.23mg=\frac{0.001}{1}\times 408.23=0.408grams\)
Thus for a body with weight of 2.20462 lb , we have to give 0.408 grams of medication.
