Calculate the flow rate in mL/hr. (Equipment used is programmable in whole mL/hr). Order: 2,000 mL D5W in 24 hr by infusion pump. Calculate rate in mL/hr.

A.

83 mL/hr

B.

75 mL/hr

C.

42 mL/hr

D.

60 mL/hr

Answer and Explanation

The Correct Answer is A

Step 1: Identify the total volume to be infused.

  • Total volume = 2,000 mL

Step 2: Identify the total time for infusion.

  • Total time = 24 hours

Step 3: Calculate the flow rate in mL/hr.

  • Flow rate = Total volume ÷ Total time
  • Flow rate = 2,000 mL ÷ 24 hours

Step 4: Perform the division.

  • 2,000 ÷ 24 = 83.3333…

Step 5: Round to the nearest whole number since the equipment is programmable in whole mL/hr.

  • Rounded flow rate = 83 mL/hr

So, the flow rate is 83 mL/hr.

Correct Answer is B

Explanation

To calculate the dosage, we need to use the formula:

Dosage (mL) = Ordered dose (mg) / Available dose (mg/mL)

Plugging in the given values, we get:

Dosage (mL) = 175 mg / 25 mg/mL

Simplifying, we get:

Dosage (mL) = 7 mL

Therefore, the dosage is 7 mL.

Correct Answer is A

Explanation

To calculate the dosage using the ratio and proportion method, we need to set up a proportion with the ordered dose and the available dose as follows:

Ordered dose (units) / Dosage (mL) = Available dose (units) / Available volume (mL)

Plugging in the given values, we get:

8,500 units / Dosage (mL) = 50,000 units / 5 mL

Cross-multiplying, we get:

50,000 units x Dosage (mL) = 8,500 units x 5 mL

Solving for Dosage (mL), we get:

Dosage (mL) = (8,500 units x 5 mL) / 50,000 units

Simplifying, we get:

Dosage (mL) = 42,500 mL / 50,000

Therefore, the dosage is 0.85 mL.
