Ati Dosage calculations RN adult medical proctored assessment 3.1 ( 32 Questions)
A nurse is preparing to administer gentamicin 5 mg/kg via intermittent IV bolus to a client who weighs 210 lb. The amount available is gentamicin 10 mg/mL. How many mL 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.)
Correct Answer: 48
To calculate the dose of gentamicin, we need to convert the client's weight from pounds to kilograms.
One pound is equal to 0.454 kg, so 210 lb is equal to 95.34 kg.
Then, we multiply the weight by the dosage to get the dose in mg.
The dosage is 5 mg/kg, so the dose is 95.34 kg x 5 mg/kg = 476.7 mg.
To find the volume in mL, we divide the dose by the concentration of the medication.
The concentration is 10 mg/mL, so the volume is 476.7 mg / 10 mg/mL = 47.67 mL.
We round this to the nearest whole number, which is 48 mL.
Therefore, the nurse should administer 48 mL of gentamicin to the client.
