Mr. Cook requires medication for nausea. Compazine 10mg po q 4hrs prn ordered. You have Compazine 5-mg tablets available. How many tablets will you administer per dose?
Correct answer
2
Rationale
The correct answer is 2 tablets. Since each tablet is 5mg, to achieve the ordered dose of 10mg, you need to administer 2 tablets. Dividing the total dose (10mg) by the dose per tablet (5mg) gives you the number of tablets needed, which is 2. Other choices are incorrect because they do not correctly calculate the number of tablets required based on the dosage strength and ordered dose.
