The doctor ordered antibiotic G 5mg/kg/day in three divided doses. The medication is supplied 100mg/mL. The patients weighs 120kg. What volume will 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 ["2.0"]
To determine the correct volume to administer per dose, follow these steps:
1. Calculate the total daily dosage:
The dosage is 5 mg/kg/day.
The patient weighs 120 kg.
Total daily dosage = 5 mg/kg x 120 kg = 600 mg/day.
2. Divide the total daily dosage by the number of doses per day:
The medication is to be given in three divided doses.
Dosage per dose = 600 mg/day / 3 = 200 mg per dose.
3. Determine the volume to administer per dose:
The medication is supplied as 100 mg/mL.
Volume per dose = 200 mg / 100 mg/mL = 2.0 mL.
4. Round to the nearest tenth:
2.0 mL is already rounded to the nearest tenth.

Correct Answer is ["0.4"]
Explanation
To determine the correct volume to administer, follow these steps:
1. Convert the available concentration to mg/mL:
6 grams = 6000 mg (since 1 gram = 1000 mg)
Therefore, 6000 mg / 10 mL = 600 mg/mL.
2. Calculate the volume to administer:
The ordered dose is 250 mg.
Volume to administer = 250 mg / 600 mg/mL = 0.4167 mL.
3. Round to the nearest tenth:
0.4167 mL rounded to the nearest tenth is 0.4 mL.
Correct Answer is ["1.5"]
Explanation
To determine the correct volume to administer, follow these steps:
1. Convert the client’s weight from pounds to kilograms:
1 pound = 0.453592 kilograms
99 pounds x 0.453592 = 44.91 kilograms (rounded to two decimal places)
2. Calculate the dosage in units:
100 units/kg x 44.91 kg = 4491 units
3. Determine the volume to administer:
The ampule contains 3000 units/mL.
4491 units / 3000 units/mL = 1.497 mL
4. Round to the nearest tenth:
1.497 mL rounded to the nearest tenth is 1.5 mL
