A client who has a sinus infection is receiving a prescription for amoxicillin/clavulanate potassium (Augmentin) 500 mg PO every 8 hours. The available form is 250 mg amoxicillin/125mg clavulanate tablets. How many tablets should the nurse administer for each dose? (Enter numeric value only.)
The Correct Answer is ["2"]
Understanding the Problem:
We need to administer 500 mg of amoxicillin/clavulanate potassium.
The available tablets contain 250 mg amoxicillin and 125 mg clavulanate potassium.
Solution:
Determine the total amount of active ingredients in the available tablets:
250 mg (amoxicillin) + 125 mg (clavulanate potassium) = 375 mg/tablet
Calculate the number of tablets needed:
500 mg (desired dose) / 375 mg/tablet = 1.33 tablets
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets for each dose.

Correct Answer is ["200"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
First, convert minutes to hours:
75 minutes x (1 hour / 60 minutes) = 1.25 hours
Then, plug in the values into the formula:
Infusion Rate = 250 mL / 1.25 hours
Calculating the result:
Infusion Rate ≈ 200 mL/hour
Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.
Correct Answer is ["22"]
Explanation
Calculating the Propofol Infusion Rate
Step 1: Convert weight to kilograms:
198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg
Step 2: Calculate the desired dose rate in mcg/minute:
8 mcg/kg/minute x 90 kg = 720 mcg/minute
Step 3: Calculate the concentration of propofol in the IV solution:
100 mg/50 mL = 2 mg/mL
Step 4: Calculate the infusion rate in mL/hour:
First, convert mcg to mg:
720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute
Then, set up a proportion:
x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL
Cross-multiply and solve for x:
x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL
x mL/hour ≈ 21.6 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.
