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 D
Explanation
The nurse should administer 2 tablets per dose to this patient.
This answer is correct because it is based on a simple unit conversion and ratio and proportion calculation. The nurse can convert 0.1 mg to 100 mcg by multiplying by 1000, since there are 1000 mcg in 1 mg. Then, the nurse can set up a proportion as follows:
50 mcg / 1 tablet = 100 mcg / x tablets
Cross-multiplying and solving for x gives:
x = 2 tablets
Therefore, the nurse should administer 2 tablets of Synthroid to deliver 0.1 mg or 100 mcg of the medication to the patient.
Correct Answer is A
Explanation
To find the milligrams per minute, you need to calculate the following:
- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)
- The dose of Lopressor in milligrams per minute using the formula: Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)
First, divide the dose of Lopressor by the concentration to get the volume in milliliters:
5 mg / 1 mg/mL = 5 mL
Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:
Infusion rate (mL/min) = Total volume (mL) / Time (min)
Since the total volume is 5 mL and the time is 2 minutes, plug in these values into the formula:
Infusion rate (mL/min) = 5 mL / 2 min
Simplify and solve for the infusion rate:
Infusion rate (mL/min) = 2.5 mL/min
Then, use the formula for dose to find how many milligrams per minute the patient should receive:
Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)
Since the infusion rate is 2.5 mL/min and the concentration is 1 mg/mL, plug in these values into the formula:
Dose (mg/min) = 2.5 mL/min x 1 mg/mL
Simplify and solve for the dose:
Dose (mg/min) = 2.5 mg/min
Therefore, the patient should receive **2.5 mg/min** of Lopressor.
