A client with hypernatremia is to receive an IV infusion of 1000 ml 5% dextrose in water to be infused over 6 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 ["167"]

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 / 6 hours

Calculating the result:

Infusion Rate ≈ 166.67 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour

Correct Answer is ["2"]

Explanation

To calculate the volume of metoclopramide to be administered, we can use the following formula:

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

Plugging in the given values:

Volume (mL) = 10 mg / 5 mg/mL

Volume (mL) = 2 mL

Now, we need to convert milliliters to teaspoons.

1 teaspoon ≈ 4.93 mL

To find the number of teaspoons needed:

Number of teaspoons = Volume (mL) / Volume per teaspoon (mL/teaspoon)

Number of teaspoons = 2 mL / 4.93 mL/teaspoon

Number of teaspoons ≈ 0.406 teaspoons

Since we cannot administer a fraction of a teaspoon, we round up to the nearest whole number.

Therefore, the nurse should administer 2 teaspoons of metoclopramide

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.
