A patient is to receive 1500mg of an anti-infective agent IV. Pharmacy sends a vial with instructions to reconstitute with enough sterile water to yield a concentration of 1 gm/10 mL. After withdrawing the required dose from the via instructions state to further dilute the medication with 100mL of NS and infuse over one hour At what rate will the nurse set the IV pump?

Answer and Explanation

The Correct Answer is ["115"]

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 ["2.0"]

Explanation

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 ["260"]

Explanation

Here's how we calculated that:

Juice: 1/2 cup = 120 mL
Gelatine: 3 oz = 90 mL
Ice pop: 1 oz = 30 mL

Total: 120 mL + 90 mL + 30 mL + 20 mL = 260
