A nurse is caring for a school-age child who has attention deficit disorder and a new prescription for methylphenidate 10 mg PO at 0800 and 1200 and 5 mg at 1600. What is the total daily dose in mg prescribed for this client? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["25"]
Identify the doses and times:
8:00 AM: 10 mg
12:00 PM (noon): 10 mg

Correct Answer is ["1"]
Explanation
Convert milligrams (mg) to micrograms (mcg):
The desired dose is 0.5 mg.
We know that 1 mg = 1000 mcg.
Therefore, 0.5 mg = 0.5 x 1000 mcg = 500 mcg.
Identify the available tablet strength:
Each tablet contains 500 mcg of haloperidol.
Set up the calculation:
We need to find out how many tablets are needed to administer 500 mcg of the medication. We can use the following formula:
(Desired dose) / (Tablet strength) = Number of tablets
Plug in the values and calculate:
(500 mcg) / (500 mcg/tablet) = 1 tablet
Correct Answer is ["6"]
Explanation
Determine the individual dose:
The total daily dose is 90 mg, divided into three equal doses.
90 mg / 3 doses = 30 mg per dose
Calculate the number of tablets per dose:
Each tablet contains 15 mg of phenelzine.
The required dose is 30 mg.
30 mg / 15 mg per tablet = 2 tablets per dose
Calculate the total number of tablets per day:
The patient takes 2 tablets per dose, and there are 3 doses per day.
2 tablets/dose x 3 doses/day = 6 tablets per day
