A nurse is teaching a client who has benign prostatic hypertrophy and has a new prescription for finasteride. Which of the following instructions should the nurse include in the teaching?
"Expect to see a response from the medication within a week."
"Avoid drinking grapefruit juice with this medication."
"Decreased libido is an adverse effect of the medication."
"Prostate-specific antigen (PSA) levels will significantly increase while taking this medication."
The Correct Answer is C
A. "Expect to see a response from the medication within a week": This is incorrect. Finasteride typically takes several months (up to 6 months) to show noticeable effects in reducing symptoms of benign prostatic hypertrophy.
B. "Avoid drinking grapefruit juice with this medication": This is incorrect. Grapefruit juice is not known to interact with finasteride. However, it is always a good practice to check for specific food and drug interactions.
C. "Decreased libido is an adverse effect of the medication": This is correct. Finasteride can cause sexual side effects, including decreased libido, erectile dysfunction, and ejaculatory disorders.
D. "Prostate-specific antigen (PSA) levels will significantly increase while taking this medication": This is incorrect. Finasteride typically lowers PSA levels, which should be considered when monitoring for prostate health.

Correct Answer is C
Explanation
A. Massage the legs: This is incorrect. Massage is contraindicated as it can cause further tissue damage and is not appropriate for frostbite.
B. Apply dry heat to the legs: This is incorrect. Dry heat can exacerbate tissue damage. Rewarming should be done using controlled, warm water immersion, not dry heat.
C. Elevate the legs: This is correct. Elevating the legs helps reduce swelling and can prevent further tissue damage. However, rewarming should be done carefully in a controlled environment.
D. Immerse the legs in cold water: This is incorrect. Immersing in cold water would worsen the frostbite. Rewarming should be done using warm (not hot) water, ideally at 37-39°C (98.6-102.2°F), for effective treatment.
Correct Answer is B
Explanation
A. Prepare the client for transfer to a facility with a hyperbaric chamber: This may be required for severe cases of carbon monoxide poisoning, but immediate intervention with high-flow oxygen is essential first.
B. Apply oxygen via a nonrebreather mask at 15 liters: Carbon monoxide poisoning requires immediate high-flow oxygen to help displace carbon monoxide from hemoglobin. This is the first step in treatment to prevent further tissue hypoxia and complications.
C. Check the client's oxygenation level with a pulse oximeter: While important, it does not address the immediate need for high-flow oxygen to treat carbon monoxide poisoning.
D. Administer intravenous (IV) fluids: IV fluids may be necessary for supportive care but are not the priority for treating carbon monoxide poisoning. The immediate need is to provide high-flow oxygen.
