The healthcare provider prescribes acyclovir 800 mg by mouth (PO) every 6 hours for an adolescent with chicken pox. The medication is available in 400 mg tablets PO. How many tablets should the nurse administer to the client every 24 hours? (Enter the numeric value only)
The Correct Answer is ["8"]
You can calculate the number of acyclovir tablets the nurse should administer every 24 hours using the following steps:
Daily Dosage: The medication is prescribed to be given every 6 hours, so to find the total daily dosage, we need to consider how many times it's administered in 24 hours:
Total Daily Doses = 24 hours / Dosage Frequency (every 6 hours)
Total Daily Doses = 24 hours / 6 hours/dose = 4 doses per day
Tablets per Dose: Since the prescribed dose is 800 mg and each tablet is 400 mg, we can find the number of tablets needed per dose:
Tablets per Dose = Prescribed Dose (mg) / Tablet Strength (mg/tablet)
Tablets per Dose = 800 mg / 400 mg/tablet = 2 tablets/dose
Total Tablets per Day: Now that we know the tablets needed per dose (2) and the total daily doses (4), we can find the total number of tablets for 24 hours:
Total Tablets per Day = Tablets per Dose x Total Daily Doses
Total Tablets per Day = 2 tablets/dose * 4 doses/day
Total Tablets per Day = 8 tablets
Therefore, the nurse should administer 8 tablets of acyclovir to the client every 24 hours.

Correct Answer is ["0.25"]
Explanation
Here's how to calculate the volume the nurse should administer after reconstituting the medication:
Reconstitution:
The medication vial is labeled "0.3 mg with 1.2 mL of sterile water." This means adding 1.2 mL of diluent will result in a total volume of 1.2 mL solution.
Important Note:
The concentration of the medication after reconstitution is not explicitly provided on the label.
We cannot directly calculate the volume to administer based solely on the prescribed dose (0.0625 mg) and the unknown concentration.
Scenario:
In real-world practice, nurses rely on the medication information sheet or the manufacturer's label for dilution instructions and the final concentration after reconstitution.
This information is crucial for calculating the accurate volume to administer the prescribed dose.
Assuming the medication information sheet specifies:
After reconstitution with 1.2 mL diluent, the final concentration is 0.25 mg/mL.
Calculation (based on the assumed concentration):
Prescribed dose: 0.0625 mg
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 0.0625 mg / 0.25 mg/mL
Volume to administer (mL) = 0.25 mL (round to nearest hundredth)
Therefore, based on the assumed concentration after reconstitution (0.25 mg/mL), the nurse should administer 0.25 mL to the client.
Correct Answer is ["0.5"]
Explanation
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.
