Ati Dosage Calculation RN Adult Medical Surgical ( 63 Questions)
A nurse is preparing to administer pentamidine 4 mg/kg IM to a client who weighs 154 lb. Available is pentamidine 100 mg/mL for injection. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
To calculate the dose of pentamidine in milliliters (mL) that the nurse should administer, we can use the following steps:
Correct Answer: 2.8 mL
Convert the patient's weight from pounds to kilograms:
154 lb ÷ 2.2 = 70 kg
Calculate the dose of pentamidine:
4 mg/kg × 70 kg = 280 mg
Determine the volume to be administered:
We have 100 mg/mL concentration of pentamidine.
280 mg ÷ 100 mg/mL = 2.8 mL
Therefore, the nurse should administer 2.8 mL of pentamidine to the client.
