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 ["1"]
Explanation
Here's the breakdown:
Prescribed dose: 2 mg midazolam (given)
Vial concentration: 4 mg/2 mL (label)
We need to find the volume containing the 2 mg dose considering the concentration.
Calculation:
Volume (mL) = Dose (mg) / (Concentration (mg/mL) / 2)
We divide the concentration by 2 because we need the volume that delivers 2 mg (half the concentration).
Volume (mL) = 2 mg / (4 mg/mL / 2)
Volume (mL) = 2 mg / 2 mg/mL
Volume (mL) = 1 mL
Therefore, the nurse should administer 1 mL of midazolam to deliver the prescribed dose of 2 mg.
Correct Answer is ["111"]
Explanation
Here's how to calculate the rate for the infusion pump:
Total volume to infuse: 1 liter (given)
Infusion time: 9 hours (given)
We need to find the volume delivered per hour (mL/hour) considering the total volume and infusion time.
Volume conversion: Since the volume is given in liters, convert it to mL:
1 liter * 1000 mL/liter = 1000 mL
Infusion rate (mL/hour):
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Infusion rate (mL/hour) = 1000 mL / 9 hours
Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest tenth)
Therefore, the nurse should program the infusion pump to deliver approximately 111 mL/hour.
