The healthcare provider prescribes a hydration IV of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 154 pounds. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
Answer and Explanation

The Correct Answer is ["699"]

First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mL/kg. 

We know that 1 kg is approximately 2.20462 pounds. So,

Weight in kg= Weight in pounds/2.20462 ​= 154 / 2.20462 ​≈ 69.85kg

The prescribed dosage is 30 mL/kg, so the total volume in mL would be:

Volume in mL= Dosage per kg × Weight in kg=30mL/kg × 69.85kg ≈ 2095.5mL

The medication is to be administered over 3 hours. Therefore, the rate in mL/hour would be:

Rate in mL/hour = Volume in mL / Time in hours ​=  2095.5mL/3hours ​ ≈ 698.5mL/hour

So, the nurse should program the infusion pump to deliver approximately 699 mL/hour.

Correct Answer is ["10"]

Explanation

First, we need to calculate the total amount of medication that will be administered in a day.

The prescription is for 250 mg every 8 hours, which means three doses per day (since there are 24 hours in a day).

Therefore, the total daily dosage is 250 mg x 3 = 750 mg.

Next, we need to find out how many milligrams are in the entire bottle.

Since each 5 mL contains 250 mg, we can calculate this by setting up a proportion:

(250 mg / 5 mL) = (Total mg / 150 mL)

Solving for Total mg gives us:

Total mg = (250 mg / 5 mL) * 150 mL Total mg = (50 * 150) Total mg = 7500 mg

Now that we know there are a total of 7500 mg in the bottle, we can determine how many days it will last by dividing this number by the total daily dosage:

Days = Total medication in bottle / Daily dosage Days = 7500 mg / (3 doses * 250mg) Days = 7500mg /750mg Days =10

Therefore, the bottle of medication will last for 10 days.

Correct Answer is ["0.1"]

Explanation

The nurse is to administer 100 mcg of cyanocobalamin.

Please note that 1 mg is equivalent to 1000 mcg,

so the concentration of the medication is 1000 mcg/mL.

Therefore, the volume of medication to administer is:

100mcg / 1000mcg/mL ​= 0.1mL

So, the nurse should administer 0.1 mL of cyanocobalamin
