A client returning from surgery has a prescription for an IV of 0.9% sodium chloride to be infused at 250 ml over 3 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Answer and Explanation

The Correct Answer is ["83"]

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 = 250 mL / 3 hours

Calculating the result:

Infusion Rate ≈ 83.33 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 83 mL/hour.

Correct Answer is ["5.8"]

Explanation

To calculate the infusion rate, we'll follow these steps:

1. Calculate the desired dose rate in mcg/minute:

Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)

Desired Dose Rate = 86 kg x 8 mcg/kg/minute

Desired Dose Rate = 688 mcg/minute

2. Convert micro-grams to milligrams:

688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute

3. Calculate the concentration of dopamine in the IV solution:

Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)

Dopamine Concentration = 800 mg / 500 mL

Dopamine Concentration = 1.6 mg/mL

4. Set up a proportion:

x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL

5. Cross-multiply and solve for x:

x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL

x mL/hour ≈ 25.8 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.

Correct Answer is ["36"]

Explanation

Calculating the Dobutamine Infusion Rate

Step 1: Convert grams to milligrams:

0.5 grams = 500 mg

Step 2: Calculate the concentration of dobutamine in the IV solution:

500 mg / 250 mL = 2 mg/mL

Step 3: Convert micro-grams to milligrams:

1200 mcg x (1 mg / 1000 mcg) = 1.2 mg

Step 4: Set up a proportion:

We want to find the infusion rate in mL/minute.

We know the desired dose rate (1.2 mg/minute) and the concentration of the medication (2 mg/mL).

Proportion:

x mL/minute / 1.2 mg/minute = 1 mL / 2 mg

Step 5: Cross-multiply and solve for x:

2x = 1.2

x = 0.6 mL/minute

Step 6: Convert mL/minute to mL/hour:

0.6 mL/minute x 60 minutes/hour = 36 mL/hour

Therefore, the nurse should program the infusion pump to deliver 36 mL/hour.
