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 ["2.4"]
Explanation
Here's how to calculate the volume (mL) the nurse should administer for cefazolin:
1. We know the following:
Prescribed dose: 800 mg cefazolin IM every 6 hours (given)
Vial content: 1 gram cefazolin (given)
However, we need to consider the reconstitution process for accurate dosage calculation.
Reconstitution information:
For IM use, add 2.5 mL sterile water for injection.
This dilution creates a total volume of 3.0 mL.
3. We need to find the concentration of cefazolin in the reconstituted solution (mg/mL).
Concentration (mg/mL) = Total drug amount (mg) / Total volume (mL) after reconstitution
Concentration (mg/mL) = 1 gram (which is 1000 mg) / 3.0 mL
Concentration (mg/mL) = 333.33 mg/mL (round to nearest tenth)
4. Now, we can find the volume to administer for the prescribed dose (800 mg) considering the concentration (333.33 mg/mL) in the reconstituted solution.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 800 mg / 333.33 mg/mL
Volume to administer (mL): 2.40 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 2.4 mL of the reconstituted cefazolin solution intramuscularly.
Correct Answer is ["2.4"]
Explanation
The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.
This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).
The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 0.25mg/mL 0.6mg / 0.25mg/mL = 2.4mL
If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.
