The healthcare provider prescribes abacavir 300 mg PO every 12 hours for a client who is HIV positive. The drug is available in 300 mg tablets. How many tablets should the nurse administer per day? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2"]
Here's the breakdown of the calculation:
The prescribed dosage is 300 mg every 12 hours.
Since there are 24 hours in a day, the client will need to take the medication 24 hours / 12 hours = 2 times per day.
Each tablet is 300 mg, which is exactly the prescribed amount per dose.
Therefore, the nurse should administer 2 tablets per day (1 tablet in the morning and 1 tablet in the evening).

Correct Answer is ["20"]
Explanation
1. Convert client weight to kilograms (kg):
Client weight (lbs) = 178
We know 1 kg = 2.2 lbs
Client weight (kg) = 178 lbs / 2.2 lbs/kg = 81.36 kg (rounded to two decimal places for accuracy)
2. Calculate the total diltiazem dosage:
Dosage per kg = 0.25 mg/kg
Client weight (kg) = 81.36 kg
Total dosage (mg) = Dosage per kg * Client weight (kg)
Total dosage (mg) = 0.25 mg/kg * 81.36 kg = 20.34 mg (rounded to two decimal places for accuracy)
3. Round the dosage to the nearest whole number for administration:
Total dosage (mg) = 20.34 mg (rounded to two decimal places)
In practice, medication dosages are typically rounded to the nearest whole number for safe and accurate administration. Therefore, the nurse should administer 20 mg of diltiazem.
Correct Answer is ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
