The healthcare provider prescribes epinephrine 0.01 mg/kg IM for an adolescent with an acute asthma episode who weighs 110 pounds. The available medication is labeled, 1 mg/mL. Based on the client's weight, how many mL should the nurse administer to this client? (Enter numerical value only, rounded to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["0.5"]

here's how to calculate the volume (mL) of epinephrine the nurse should administer:

1. Client weight conversion:

Client weight: 110 pounds

Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.

Conversion factor: 1 kg = 2.205 lbs

Client weight (kg) = 110 pounds / 2.205 lbs/kg

Client weight (kg) = 50 kg (round to nearest whole number)

2. Epinephrine dosage:

Prescribed dose: 0.01 mg/kg (given)

3. Epinephrine concentration:

The medication is labeled 1 mg/mL. This indicates there are 1 mg of epinephrine per 1 mL of solution.

4. We need to find the volume (mL) containing the prescribed dose (based on weight) of epinephrine (0.01 mg/kg) considering the concentration (1 mg/mL) in the vial.

Total epinephrine dose (mg): Dose (mg/kg) x Client weight (kg)

Total epinephrine dose (mg): 0.01 mg/kg * 50 kg

Total epinephrine dose (mg): 0.5 mg (round to nearest tenth)

Volume to administer (mL): Total dose (mg) / Concentration (mg/mL)

Volume to administer (mL): 0.5 mg / 1 mg/mL

Volume to administer (mL): 0.5 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 0.5 mL of epinephrine intramuscularly.

Correct Answer is ["1.5"]

Explanation

First, we need to convert the prescribed dose from mg to mcg because the available medication is labeled in mcg.

1 mg is equal to 1,000 mcg. So, 0.075 mg is equal to 75 mcg.

Given:

The prescription is for 75 mcg of levothyroxine.

The available medication is 50 mcg/tablet.

We can set up the proportion as follows:

75mcg/ xtablet ​= 50mcg/1tablet ​

Solving for x gives us the number of tablets that the nurse should administer.

Cross-multiplying and solving for x:

X = 75mcg×1tablet​/50mcg

After performing the calculation, we find that x equals 1.5 tablets.

So, the nurse should administer 1.5 tablets of the medication. This is rounded to the nearest tenth as per the instructions.

Correct Answer is ["100"]

Explanation

The nurse should set the infusion pump to deliver the entire 150 mL over the course of 90 minutes.

First, convert the time from minutes to hours because the rate is required in mL/hr.

90 minutes is 1.5 hours (since 1 hour = 60 minutes).

Therefore, the IV pump should be set to deliver:

Rate(mL/hr)=Time(hr)Totalvolume(mL)​=1.5hr150mL​

After performing the calculation, we find that the rate equals 100 mL/hr.

So, the nurse should set the infusion pump to deliver 100 mL/hr. This is rounded to the nearest whole number as per the instructions.
