A nurse is preparing to administer diphenhydramine 50 mg PO every 6 hours to a client who has acute dystonia.
Available are diphenhydramine 25 mg tablets. How many tablets should the nurse administer per dose?
(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 ["2"]
Step 1: The total amount of diphenhydramine required per dose is 50 mg.
Step 2: Each tablet contains 25 mg of diphenhydramine.
Step 3: To find out how many tablets are needed, we divide the total amount required by the amount in each tablet. So, 50 mg ÷ 25 mg/tablet.
Step 4: The result is 2 tablets.
So, the nurse should administer 2 tablets per dose. This is already a whole number, so no rounding is necessary.

Correct Answer is B
Explanation
Choice A reason: Taking too many showers does not increase susceptibility to UTIs by washing o? protective bacteria. This is a misconception.
Choice B reason: Females do have a shorter urethra than males, which makes it easier for bacteria to reach the bladder and cause infections.
Choice C reason: While E. coli is a common bacteria causing UTIs, stating that females have more E. coli is incorrect and not a reason for increased UTIs.
Choice D reason: Sexual activity can increase the risk of UTIs, but it is not appropriate to assume that the client's age correlates with increased sexual activity.
