A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is tobramycin 40 mg/ml. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.1"]
To calculate the amount of tobramycin to administer per dose, you need to follow these steps:
Step 1: Calculate the total daily dose. Total Daily Dose (mg) = Weight (kg) x Dose (mg/kg/day)
Total Daily Dose (mg) = 85 kg x 3 mg/kg/day = 255 mg/day
Step 2: Calculate the dose per divided dose (three divided doses). Dose per Divided Dose (mg) = Total Daily Dose (mg) / Number of Divided Doses
Dose per Divided Dose (mg) = 255 mg / 3 doses = 85 mg/dose
Step 3: Convert the dose to mL using the concentration. Dose (mL) = Dose (mg) / Concentration (mg/mL)
Dose (mL) = 85 mg / 40 mg/mL ≈ 2.125 mL
Rounded to the nearest tenth, the nurse should administer 2.1 mL per dose.

Correct Answer is ["167"]
Explanation
To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)
Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr
Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.
