A nurse is preparing to administer liquid ibuprofen to a school-age child. The prescription reads 200 mg every 8 hr. The amount available is 100 mg/5 mL. How many mL of ibuprofen should the nurse administer over a 24-hr period? (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 ["30"]
To calculate the dosage of ibuprofen in milliliters for a 24-hour period, we start by determining the total milligrams required per day. Since the prescription is for 200 mg every 8 hours, the child will need three doses in 24 hours (200 mg x 3 = 600 mg). Next, we convert the total milligrams into milliliters using the concentration provided. The formula is: (Total mg needed / Concentration of mg) x Volume of each concentration = Total mL. Plugging in the numbers: (600 mg / 100 mg) x 5 mL = 30 mL.

Correct Answer is B
Explanation
A. A urine collection device is not appropriate for collecting stool specimens. It is designed for urine collection, not stool.
B. This method is suitable for collecting a stool specimen for the purpose of checking for ova and parasites if a stool sample is not immediately available. It helps ensure that the sample is collected directly from the rectal area.
C. Povidone-iodine (Betadine) can interfere with the results of ova and parasite testing. It is not appropriate to use it for transferring or handling stool specimens.
D. Stool specimens for ova and parasites should ideally be kept cool and sent to the lab as soon as possible. Room temperature storage can affect the integrity of the specimen and impact the accuracy of the test.
