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 C

Explanation

To find the milliliters 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)

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 60 seconds or 1 minute, plug in these values into the formula:

Infusion rate (mL/min) = 5 mL / 1 min

Simplify and solve for the infusion rate:

Infusion rate (mL/min) = 5 mL/min

Therefore, the nurse should administer **5 mL/min** to infuse Lopressor 5 mg over 60 seconds.

Correct Answer is B

Explanation

One inch is equal to **2.54 centimeters**²³⁴. To convert inches to centimeters, you can multiply the value in inches by 2.54. For example, 2.54 centimeters x 1 inch = 2.54 centimeters.

Therefore, to convert 2.54 centimeters to inches, you can divide the value in centimeters by 2.54. For example, 2.54 centimeters / 2.54 = 1 inch.

The answer is **1 inch**.
