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 ["15"]

Explanation

Here's what we know:

Volume remaining in the bag: 630 mL

Total volume to be infused (remaining volume): 630 mL (since we're using the remaining volume)

Infusion time: 7 hours

Drop factor (delivery rate per mL): 10 gtt/mL

We need to find:

Infusion rate (gtt/min)

Steps to solve:

Convert hours to minutes:

Infusion time (hours) = 7

Conversion factor: 1 hour = 60 minutes

Infusion time (minutes) = 7 hours x 60 minutes/hour = 420 minutes

Calculate the required infusion rate (gtt/min):

Total volume to be infused (mL) = 630 mL

Drop factor (gtt/mL) = 10 gtt/mL

Infusion time (minutes) = 420 minutes

Infusion rate (gtt/min) = (Total volume (mL) / Infusion time (minutes)) x Drop factor (gtt/mL)

Infusion rate (gtt/min) = (630 mL / 420 minutes) x 10 gtt/mL

Infusion rate (gtt/min) = 15 gtt/min (rounded to the nearest whole number)

Therefore, the nurse should regulate the infusion to deliver approximately 15 drops/minute.

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.
