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.)

Answer and Explanation

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 ["50"]

Explanation

First, let’s calculate the current infusion rate in mL/hour.

The IV solution contains 20,000 units of heparin in 500 mL, so the concentration is:

Concentration = Totalunits/ Totalvolume = 20,000units /500mL = 40units/mL

The client is currently receiving 1,800 units/hour. At a concentration of 40 units/mL, this dosage is equivalent to:

Currentrate = Dose/ Concentration = 1,800units/hour / 40units/mL = 45mL/hour

The healthcare provider prescribed an increase of 5 mL/hour in the IV rate. Therefore, the new rate should be:

Newrate = Currentrate + Increase = 45mL/hour + 5mL/hour = 50mL/hour

So, the nurse should set the infusion pump to deliver 50 mL/hour. If rounding is required, this is already rounded to the nearest whole number.

Correct Answer is ["100"]

Explanation

Here's how to calculate the infusion rate (mL/hour) for the cefazolin administration:

1. We know:

Total volume of cefazolin solution (including 0.9% sodium chloride): 50 mL (given)

Amount of cefazolin to administer: 1 gram (convert to mg for calculation) = 1 g * 1000 mg/g = 1000 mg

Infusion time: 30 minutes (given) = 30 minutes / 60 minutes/hour = 0.5 hours

2. We need to find:

Infusion rate (mL/hour)

3. Calculation:

The medication (cefazolin) is diluted in sodium chloride solution, but the total volume (50 mL) includes both. We only need to administer this entire volume over the specified time.

Infusion rate (mL/hour) = Total volume of solution (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 50 mL / 0.5 hours

Infusion rate (mL/hour) = 100 mL/hour

Therefore, the nurse should program the infusion pump to deliver 100 mL/hour.
