A client weighing 86 kg is receiving dopamine at 8 mcg/kg/minute. The drug is dispensed as dopamine 800 mg/500 ml. 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 tenth.)
Answer and Explanation

The Correct Answer is ["5.8"]

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 ["0.13"]

Explanation

To calculate the volume of phytonadione (AquaMEPHYTON) to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

First, let's convert the desired dose from micro-grams to milligrams:

250 mcg x (1 mg / 1000 mcg) = 0.25 mg

Then, plug in the values into the formula:

Volume (mL) = 0.25 mg / 2 mg/mL

Calculating the result:

Volume (mL) = 0.125 mL

Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).

Correct Answer is ["40"]

Explanation

Calculating the Inamrinone Infusion Rate

Step 1: Convert weight to kilograms:

183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg

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

8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute

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

0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL

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

First, convert mcg to mg:

664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute

Then, set up a proportion:

x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL

x mL/hour ≈ 40 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
