A nurse is preparing to administer gentamicin to a client who weighs 165 lb. The medication reference recommends administering 2 mg/kg IM

every 8 hr. How many mg should the nurse plan to administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it

applies. Do not use a trailing zero.)

Number of mg to be administered=150 mg

Step-by-step explanation:

This can be expressed as;

Dose per weight=Number of mg doses to be administered/Total weight

where;

Dose per weight=2 mg/kg

Number of mg doses to be administered=x

Total weight=165 lb

1 kilogram=2.205 pounds

Total weight in kilograms=165/2.205=74.83 kg

replacing;

Number of mg doses to be administered=Dose per weight*Total weight

x=2*74.83=149.66 mg

Number of mg doses to be administered=150 mg
