The healthcare provider prescribes a slow continuous infusion of labetalol to be administered at 2mg/minute. Labetalol HCI Injection, USP 200 mg/40 mL is added to 160 mL of 5% Dextrose Injection, USP for a total volume of 200 mL. How many mL/hour should the nurse program the infusion pump?

(Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["6"]

To calculate the infusion rate in mL/hour, we can use the following formula:

Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:

200 mg/40 mL = 5 mg/mL

We can calculate the infusion rate as follows:

2 mg/minute x 60 / 5 mg/mL = 24 mL/hour

However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:

200 mL / (120 minutes) = 100 mL/hour

So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:

2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:

X = (2 x 60 x 1) / 5 = 24 mL/hour

So we should program the infusion pump to deliver 6 mL/hour.

Correct Answer is ["0.25"]

Explanation

The child weighs 55 pounds which is equivalent to 24.95 kg (1 kg = 2.20462 pounds).

The healthcare provider prescribes epinephrine 0.01 mg/kg, so the child should receive 0.2495 mg of epinephrine (0.01 mg/kg 24.95 kg).

The available medication is labeled 1 mg/mL, so the nurse should administer 0.25 mL of medication (0.2495 mg / 1 mg/mL).

Correct Answer is ["97.7"]

Explanation

To convert Celsius to Fahrenheit, we can use the following formula:

°F = (°C x 1.8) + 32

In this case, the oral temperature is 36.5°C. We can calculate the temperature in Fahrenheit as follows: (36.5 x 1.8) + 32 = 97.7°F.
