A client with dehydration receives a prescription for an IV of Lactated Ringer's 1,000 ml to be administered over 8 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only, using whole number.)
Answer and Explanation

The Correct Answer is ["125"]

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

Plugging in the given values:

Infusion Rate = 1000 mL / 8 hours

Calculating the result:

Infusion Rate = 125 mL/hour

Therefore, the nurse should program the infusion pump to deliver 125 mL/hour.

Correct Answer is ["22"]

Explanation

Calculating the Propofol Infusion Rate

Step 1: Convert weight to kilograms:

198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 90 kg = 720 mcg/minute

Step 3: Calculate the concentration of propofol in the IV solution:

100 mg/50 mL = 2 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute

Then, set up a proportion:

x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL

x mL/hour ≈ 21.6 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.

Correct Answer is ["1.5"]

Explanation

Understanding the Problem:

We need to administer 15 mg of furosemide.

The available ampoule contains 10 mg/mL of furosemide.

Solution:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (15 mg) and the concentration of the medication (10 mg/mL).

Proportion:

x mL / 15 mg = 1 mL / 10 mg

Cross-multiply:

10x = 15

Solve for x:

x = 15 / 10

x = 1.5

Therefore, the nurse should administer 1.5 mL of furosemide.
