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 mL\/hour."]

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 ["75ml\/hour"]

Explanation

The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour.

Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL).

Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).

Correct Answer is ["2.5 tablets per day"]

Explanation

The client weighs 172 pounds which is equivalent to 78.02 kg (1 kg = 2.20462 pounds).

The prescription for levothyroxine is 1.6 mcg/kg/day, so the client should receive 124.83 mcg of levothyroxine per day (1.6 mcg/kg/day * 78.02 kg).

The medication is available in 50 mcg scored tablets, so the nurse should administer 2.5 tablets per day (124.83 mcg / 50 mcg/tablet).
