A physician ordered Reglan (metoclopramide) 10 mg to be mixed with 50 mL normal saline and infused over 15 minutes. A nurse must set the IV pump to deliver the medication per mL/hr as ordered.
At what rate should the solution be administered?
200 mL/hr
100 mL/hr
50 mL/hr
300 mL/hr
300 mL/hr
The Correct Answer is A
The physician ordered Reglan (metoclopramide) 10 mg to be mixed with 50 mL of normal saline and infused over 15 minutes. Since the infusion time is 15 minutes (0.25 hours), we can calculate the rate per hour to administer the solution as follows: (50 mL / 0.25 hours) = 200 mL/hour.
B. 100 mL/hr is incorrect because it would take 30 minutes to infuse the solution.
C. 50 mL/hr is incorrect because it would take 1 hour to infuse the solution.
D. 300 mL/hr is incorrect because it would only take 10 minutes to infuse the solution.

Correct Answer is B
Explanation
To calculate the dose of the medicine per day, we need to determine how many times the medication is administered in a day and multiply it by the dose per administration.
The prescription states that the medication is to be taken every 4 hours (q4h), which means it will be
administered 24 hours divided by 4 hours, which is 6 times per day.
The dose of the medicine per administration is 0.3 mcg.
To calculate the dose per day, we multiply the dose per administration by the number of administrations
per day:
Dose per day = Dose per administration × Number of administrations per day
Dose per day = 0.3 mcg × 6 administrations
Dose per day = 1.8 mcg/day
Correct Answer is C
Explanation
The patient is ordered to take 600 mg of ibuprofen every 6 hours as needed. In 24 hours, there are four 6- hour intervals. Therefore, the maximum dose of ibuprofen the patient may have in 24 hours is 600 mg * 4 = 2400 mg.
Since the tablets are available in 200 mg per tablet, the maximum number of tablets the patient may have
in 24 hours is 2400 mg / 200 mg/tablet = 12 tablets.
A. 6 tablets is incorrect because it is half the calculated number of tablets.
B. 4 tablets is incorrect because it is one-third the calculated number of tablets.
C. 12 tablets is the correct answer.
D. 3 tablets is incorrect because it is one-fourth the calculated number of tablets.
