The health-care provider prescribes the adjustment of the IV hourly rate based on the nasogastric tube (NGT) output every 4 hour for a client who had abdominal surgery yesterday. From 1200 to 1600, the NGT output was 240 ml, and the IV of Dextrose 5% in 0.45% Sodium chloride (D, 1/2 NS) was infused at a rate of 100 ml/hour. At 1600 the nurse should regulate the IV to deliver how many ml/hour to replace this fluid loss? (Enter numeric value only, using a whole number.)
Answer and Explanation

The Correct Answer is ["160"]

Calculate the average hourly NGT output:

Average Hourly NGT Output = Total NGT Output / Number of Hours

Average Hourly NGT Output = 240 mL / 4 hours

Average Hourly NGT Output = 60 mL/hour

Adjust the IV rate:

New IV Rate = Current IV Rate + Average Hourly NGT Output

New IV Rate = 100 mL/hour + 60 mL/hour

New IV Rate = 160 mL/hour

Therefore, the nurse should regulate the IV to deliver 160 mL/hour to replace the fluid loss.

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.

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.
