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 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.

A. 10 hours B. 7.5 hours C. 20 hours D. 15 hours

Correct Answer is C

Explanation

To find the hours to finish the infusion, you need to calculate the following:

- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)

First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:

1.5 L x 1000 = 1500 mL

Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:

Time (h) = Total volume (mL) / Infusion rate (mL/h)

Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:

Time (h) = 1500 mL / 75 mL/h

Simplify and solve for the time:

Time (h) = 20 h

Therefore, it will take **20 hours** to finish the infusion at the current rate.
