A child who weighs 44 pounds with otitis media receives a prescription for azithromycin 10 mg/kg once, then 10 mg/kg daily for 4 days. The medication is available in a solution containing 200 mg/5mL. How many mL should the nurse administer on the first day of the treatment regimen? (Enter numeric value only.)
The Correct Answer is ["5"]
Here's how to calculate the volume of medication the nurse should administer on the first day:
1. Convert child's weight to kilograms (kg):
We know 1 kg = 2.205 pounds.
Child weight (kg) = 44 pounds / 2.205 pounds/kg = 20 kg (round to nearest whole number for this calculation).
2. Calculate the total azithromycin medication for the first day (mg):
Prescribed dosage (mg/kg): 10 mg/kg
Child weight (kg): 20 kg (rounded value from step 1)
Total medication on day 1 (mg) = Dosage (mg/kg) x Client weight (kg)
Total medication on day 1 (mg) = 10 mg/kg x 20 kg = 200 mg
3. Determine the volume (mL) needed based on the medication concentration:
Medication concentration (mg/mL): 200 mg/5 mL (given)
Total medication on day 1 (mg): 200 mg (calculated in step 2)
Volume to administer (mL) = Total medication (mg) / Concentration (mg/mL)
Volume to administer (mL) = 200 mg / 200 mg/5 mL
Volume to administer (mL) = 5 mL
Therefore, the nurse should administer 5 mL of the azithromycin solution on the first day.

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 ["4.7"]
Explanation
Here's how to calculate the volume (mL) of the reconstituted ampicillin solution the nurse should administer for each dose:
1. We know the following:
Prescribed dose: 140 mg ampicillin (given)
Vial information:
Contains 250 mg ampicillin powder (given)
Reconstituted with 8.3 mL sterile normal saline (given)
Yields a final concentration of 30 mg/mL (given)
2. We need to find the volume (mL) of the reconstituted solution containing the prescribed dose (140 mg) considering the final concentration (30 mg/mL).
Steps:
a. Don't consider the initial volume (8.3 mL) of sterile normal saline. The final concentration (30 mg/mL) refers to the concentration in the diluted solution after adding the saline.
b. Use the following formula:
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
c. Plug in the values:
Volume to administer (mL) = 140 mg / 30 mg/mL
Volume to administer (mL) = 4.67 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 4.7 mL of the reconstituted ampicillin solution intravenously every 8 hours for the child.
