A doctor has ordered 600 mg of ibuprofen every 6 hours as needed for a patient for postsurgical pain. The tablets are available in 200 mg per tablet.
What is the maximum number of tablets the patient may have in 24 hours?

6 tablets

12 tablets

4 tablets

3 tablets

Answer and Explanation

The Correct Answer is B

To find the maximum number of tablets the patient may have in 24 hours, you need to calculate the following:

- The number of doses the patient may have in 24 hours using the formula: Number of doses = 24 hours / Dosing interval (hours)
- The total dose of ibuprofen in milligrams (mg) for 24 hours using the formula: Total dose (mg) = Number of doses x Prescribed dose (mg)
- The number of tablets of ibuprofen using the formula: Number of tablets = Total dose (mg) / Strength per tablet (mg)

First, use the formula for number of doses to find how many times the patient may take ibuprofen in 24 hours:

Number of doses = 24 hours / Dosing interval (hours)

Since the dosing interval is 6 hours, plug in this value into the formula:

Number of doses = 24 hours / 6 hours

Simplify and solve for the number of doses:

Number of doses = 4

Next, use the formula for total dose to find the amount of ibuprofen in milligrams for 24 hours:

Total dose (mg) = Number of doses x Prescribed dose (mg)

Since the number of doses is 4 and the prescribed dose is 600 mg, plug in these values into the formula:

Total dose (mg) = 4 x 600 mg

Simplify and solve for the total dose:

Total dose (mg) = 2400 mg

Then, use the formula for number of tablets to find how many tablets of ibuprofen are needed:

Number of tablets = Total dose (mg) / Strength per tablet (mg)

Since the total dose is 2400 mg and the strength per tablet is 200 mg, plug in these values into the formula:

Number of tablets = 2400 mg / 200 mg

Simplify and solve for the number of tablets:

Number of tablets = 12

Therefore, the maximum number of tablets the patient may have in 24 hours is **12**.

Correct Answer is D

Explanation

The nurse should administer 4 mL to this patient.

This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:

2 mg / 1 mL = 8 mg / x mL

Cross-multiplying and solving for x gives:

x = 4 mL

Therefore, the nurse should administer 4 mL of ondansetron to deliver 8 mg of the medication to the patient.

A. 50 mL B. 100 mL C. 250 mL D. 500 mL

Correct Answer is C

Explanation

The nurse should add 250 mL of water to the formula to dilute it to half strength.

This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:

250 mL / 1 = x mL / 0.5

Cross-multiplying and solving for x gives:

x = 500 mL

Therefore, the nurse should add 250 mL of water to the formula to make a total volume of 500 mL, which is half the concentration of the original formula.
