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 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
