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 ["115"]
Explanation
Let's calculate the IV pump rate step-by-step:
1. Determine the total volume to be infused:
The medication is initially reconstituted to a concentration of 1 g/10 mL.
To obtain 1500 mg (or 1.5 g), we need 1.5 g * 10 mL/g = 15 mL.
After further dilution with 100 mL of NSS, the total volume becomes 15 mL + 100 mL = 115 mL.
2. Determine the infusion rate:
The infusion time is given as 1 hour.
To calculate the infusion rate, divide the total volume by the infusion time:
115 mL / 1 hour = 115 mL/hour
Correct Answer is ["4"]
Explanation
To determine the number of units per hour the client is receiving, follow these steps:
1. Calculate the concentration of insulin in units per mL:
The infusion contains 75 units of insulin in 150 mL of Normal Saline.
Therefore, 75 units / 150 mL = 0.5 units/mL.
2. Determine the infusion rate in units per hour:
The infusion rate is 8 mL per hour.
Using the concentration, 8 mL/hr x 0.5 units/mL = 4 units/hr.
