A client is to receive antibiotics 1,000,000 units IV. Package instructions are to mix the medication with enough sterile water to yield a concentration of 250,000 units per 4mL. After withdrawing the required dose from the vial, package instruction are to further dilute in 100mL of IV fluid and run it over 1 hour. At what raet should the nurse set the IV pump?

Answer and Explanation

The Correct Answer is ["116"]

Let's calculate the IV pump rate step-by-step:

1. Determine the total volume of the medication:
The desired dosage is 1,000,000 units.
The concentration of the reconstituted medication is 250,000 units per 4 mL.
To find the total volume needed, divide the desired dosage by the concentration:
1,000,000 units / 250,000 units/4 mL = 4 x 4 mL = 16 mL

2. Calculate the final volume after dilution:
The reconstituted medication (16 mL) is further diluted with 100 mL of IV fluid.
The total volume after dilution is 16 mL + 100 mL = 116 mL.

3. 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:
116 mL / 1 hour = 116 mL/hour

Correct Answer is ["20"]

Explanation

Let's calculate the dosage step-by-step:

1. Determine the concentration of the medication in the suspension:
125 mg / 5 mL = 25 mg/mL

2. Calculate the volume needed:
500 mg / 25 mg/mL = 20 mL

Correct Answer is ["2.5"]

Explanation

To determine the correct volume to administer, follow these steps:
1. Convert the dose from milligrams to grams:
75 mg = 0.075 grams (since 1000 mg = 1 gram)

2. Use the concentration of the suspension to find the volume:
The concentration is 0.15 g/5 mL.
Set up a proportion: (0.15 g / 5 mL) = (0.075 g / X mL)
Solve for X: X = (0.075 g x 5 mL) / 0.15 g = 2.5 mL

3. Round to the nearest tenth:
2.5 mL is already rounded to the nearest tenth.
