A healthcare provider prescribes one 250 mg capsule of amoxicillin to be administered tid for 5 days to a client.
Calculate the number of capsules of amoxicillin required for 5 days.
15 capsules
5 capsules
25 capsules
3 capsules
The Correct Answer is A
To find the number of capsules of amoxicillin required for 5 days, you need to calculate the following:
- The total dose of amoxicillin in milligrams (mg) for 5 days using the formula: Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
- The number of capsules of amoxicillin using the formula: Number of capsules = Total dose (mg) / Strength per capsule (mg)
First, use the formula for total dose to find the amount of amoxicillin in milligrams for 5 days:
Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
Since the prescribed dose is 250 mg, the frequency is 3 times per day, and the duration is 5 days, plug in these values into the formula:
Total dose (mg) = 250 mg x 3 times/day x 5 days
Simplify and solve for the total dose:
Total dose (mg) = 3750 mg
Next, use the formula for number of capsules to find how many capsules of amoxicillin are needed:
Number of capsules = Total dose (mg) / Strength per capsule (mg)
Since the total dose is 3750 mg and the strength per capsule is 250 mg, plug in these values into the formula:
Number of capsules = 3750 mg / 250 mg
Simplify and solve for the number of capsules:
Number of capsules = 15
Therefore, the client needs **15 capsules** of amoxicillin for 5 days.

Correct Answer is B
Explanation
The nurse should administer 1050 mg of medication to achieve the total prescribed dose.
This answer is correct because it is based on a simple multiplication calculation. The nurse can multiply the prescribed dose per kilogram by the weight of the client in kilograms to get the total dose in milligrams, as follows:
25 mg/kg x 42 kg = 1050 mg
Therefore, the nurse should administer 1050 mg of medication to the client.
Correct Answer is A
Explanation
To set the IV pump correctly, you need to calculate the following:
- The patient's weight in kilograms
- The dose of Zofran in milligrams
- The infusion rate in milliliters per hour
First, convert the patient's weight from pounds to kilograms by dividing by 2.2:
176 lb / 2.2 = 80 kg
Next, multiply the patient's weight by the dose of Zofran per kilogram to get the total dose in milligrams:
80 kg x 0.15 mg/kg = 12 mg
Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:
Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h
Since the medication is mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:
Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 200 mL/h
