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 ["10"]
Explanation
To determine how many milliliters (mL) of the reconstituted penicillin G potassium to administer, you can use the following calculation:
Given:
- Reconstituted concentration: 100,000 units/mL
- Total dose to be administered: 1,000,000 units
Now, use the formula:
Volume (mL) = Total dose (units) / Concentration (units/mL)
Volume (mL) = 1,000,000 units / 100,000 units/mL
Volume (mL) = 10 mL
So, the nurse should administer 10 mL of the reconstituted penicillin G potassium.
Correct Answer is ["3"]
Explanation
To calculate how many tablets of pyrazinamide the nurse should administer, you can use the following steps:
Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 165 lb / 2.2 ≈ 75 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 75 kg × 20 mg/kg = 1500 mg
Determine the number of tablets needed:
Number of tablets = Total dosage / Tablet strength Number of tablets = 1500 mg / 500 mg/tablet = 3 tablets
The nurse should administer 3 tablets of pyrazinamide
