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 C

Explanation

A. Anthrax: This is incorrect. While a vaccine is available for anthrax, it is generally administered as a pre-exposure prophylaxis, not as a treatment following exposure.
B. Sarin: This is incorrect. Sarin is a nerve agent for which there is no vaccine. Treatment focuses on immediate decontamination and administration of antidotes like atropine.
C. Smallpox: This is correct. A vaccine for smallpox is administered following exposure as a post-exposure prophylaxis, as smallpox is a virus for which immediate vaccination can help prevent the disease.
D. Botulism: This is incorrect. Botulism is treated with antitoxin rather than a vaccine. There is no post-exposure vaccine available for botulism.

A. A 28-year-old client who has a history of pelvic inflammatory disease B. A 26-year-old client who is mobile post appendectomy C. A 38-year-old client who reports smoking one pack of cigarettes every day D. A 32-year-old client who has fibrocystic breast disease

Correct Answer is C

Explanation

A. A 28-year-old client who has a history of pelvic inflammatory disease: This is incorrect. While a history of pelvic inflammatory disease does not necessarily contraindicate oral contraceptive use, it should be assessed for any other potential complications or contraindications.
B. A 26-year-old client who is mobile post appendectomy: This is incorrect. Recent surgery, such as an appendectomy, is not a contraindication for oral contraceptives, provided the client is otherwise healthy.
C. A 38-year-old client who reports smoking one pack of cigarettes every day: This is correct. Smoking, especially in women over 35, is a contraindication for oral contraceptives due to the increased risk of cardiovascular events such as thrombosis.
D. A 32-year-old client who has fibrocystic breast disease: This is incorrect. Fibrocystic breast disease does not contraindicate the use of oral contraceptives.
