A nurse is preparing to administer gentamicin 2 mg/kg IV to a client who weighs 220 Ib.
How many mg should the nurse administer? (Round the answer to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.).
200 mg.
180 mg.
400 mg.
440 mg.
The Correct Answer is A
To calculate the dose of gentamicin to administer to a client who weighs 220 Ib, first convert the client’s weight from pounds to kilograms.
220 Ib is equivalent to 100 kg (220 Ib /.2 Ib/kg = 100 kg).
Then, multiply the client’s weight in kilograms by the dose of gentamicin per kilogram: 100 kg * 2 mg/kg = 200 mg.
Therefore, the nurse should administer 200 mg of gentamicin.
Choice B is wrong because 180 mg is not the correct dose.
Choice C is wrong because 400 mg is not the correct dose.
Choice D is wrong because 440 mg is not the correct dose.
