A client was found in a parked car with the motor running. The paramedic brought the client to the emergency department with complaints of a headache, nausea, and dizziness and the client is unable to recall their name or address. On assessment, the nurse notes the buccal mucosa is a cherry-red color. Which intervention should the nurse implement first?

Prepare the client for transfer to a facility with a hyperbaric chamber.

Apply oxygen via a nonrebreather mask at 15 liters.

Check the client's oxygenation level with a pulse oximeter.

Administer intravenous (IV) fluids.

Answer and Explanation

The Correct Answer is B

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.

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.

A. Strict adherence to oral contraceptive use is necessary to maintain hormonal balance. B. Surgical removal of ovarian cysts is the primary treatment for PCOS. C. PCOS cannot be managed, and no treatment options are available. D. Weight loss and lifestyle modifications can help improve PCOS symptoms.

Correct Answer is D

Explanation

A. Strict adherence to oral contraceptive use is necessary to maintain hormonal balance: This is incorrect. Oral contraceptives can help manage symptoms of PCOS by regulating menstrual cycles and reducing androgen levels, but they are not the only solution. Lifestyle modifications and weight loss can also significantly impact hormonal balance.
B. Surgical removal of ovarian cysts is the primary treatment for PCOS: This is incorrect. Surgery is not the primary treatment for PCOS. Management typically focuses on lifestyle changes and medications rather than surgical intervention.
C. PCOS cannot be managed, and no treatment options are available: This is incorrect. PCOS can be managed with a combination of lifestyle changes, medications, and, in some cases, surgical options.
D. Weight loss and lifestyle modifications can help improve PCOS symptoms: This is correct. Weight loss and lifestyle changes are fundamental in managing PCOS symptoms, as they can help improve insulin sensitivity and reduce androgen levels, which can alleviate symptoms and improve fertility.
