Calculate the number of capsules of amoxicillin required for 5 days.

A.

15 capsules

B.

5 capsules

C.

25 capsules

D.

3 capsules

Answer and Explanation

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

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.

Correct Answer is B

Explanation

The dose of the medicine per day is 1.8 mcg.

This answer is correct because it is based on a simple multiplication calculation. The nurse should follow these steps to calculate the dose of the medicine per day:

1) Divide 24 hours by the frequency of the dose to get the number of doses per day, as follows:

24 / 4 = 6

Therefore, the client will receive 6 doses of the medicine per day.

2) Multiply the number of doses per day by the amount of each dose to get the total dose per day, as follows:

6 x 0.3 mcg = 1.8 mcg

Therefore, the dose of the medicine per day is 1.8 mcg.
