A client receives a prescription for 2 liters of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["56"]

Answer: 56 gtt/min.

Rationale:

To calculate the infusion rate in gtt/min, we'll use the following formula:

Infusion Rate (gtt/min) = Volume (mL) / Time (min) x Drop Factor (gtt/mL)

1. Convert volume to mL:

2 liters = 2000 mL

2. Convert time to minutes:

12 hours = 12 x 60 = 720 minutes

3. Plug in the values:

Infusion Rate (gtt/min) = 2000 mL / 720 min x 20 gtt/mL

4. Calculate:

Infusion Rate (gtt/min) ≈ 55.56 gtt/min

5. Round to the nearest whole number:

Infusion Rate (gtt/min) ≈ 56 gtt/min

Therefore, the nurse should regulate the infusion to 56 gtt/min.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate in mL/hour, we can use the following formula Infusion rate (mL/hour) = Volume (mL) / Time (hours)

In this case, the volume is 1000 mL and the time is 12 hours. We can calculate the infusion rate as follows: 1000 mL / 12 hours = 83.3 mL/hour

We should round this value to the nearest whole number, which gives us 83 mL/hour.

Correct Answer is ["20"]

Explanation

The client is currently receiving an infusion labeled as 5% Dextrose Injection 500 mL with heparin sodium 25,000 Units. The concentration of heparin in the IV solution is 50 units/mL (25,000 units / 500 mL).

A prescription is received to change the rate of the infusion to heparin 1,000 units/hour.

Since the concentration of heparin in the IV solution is 50 units/mL, the nurse should program the infusion pump to deliver 20 mL/hour of the IV solution (1,000 units/hour / 50 units/mL).
