A nurse working in an emergency department is caring for a client who has third-degree frostbite to both lower extremities. The nurse should take which of the following actions?

Massage the legs.

Apply dry heat to the legs.

Elevate the legs.

Immerse the legs in cold water.

Answer and Explanation

The Correct Answer is C

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 A

Explanation

A. Transmission of the disease will not occur when my lesions are gone: This is incorrect. Genital herpes can still be transmitted even when lesions are not present, due to asymptomatic viral shedding.
B. The use of condoms will reduce the risk of transmission: This is correct. Condoms can reduce the risk of transmission but do not completely eliminate it, as herpes can be transmitted through skin-to-skin contact not covered by the condom.
C. Antiviral medications will not cure the infection: This is correct. Antiviral medications help manage symptoms and reduce the frequency of outbreaks but do not cure herpes.
D. Abstaining from sexual activity reduces the risk of transmission of the disease: This is correct. Abstaining from sexual activity during outbreaks or when symptoms are present reduces the risk of spreading the virus.

C. "Breathing in carbon monoxide can cause headaches and nausea." This is correct. Symptoms of carbon monoxide poisoning include headaches, nausea, and dizziness.
