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. Initiate intravenous (IV) access for fluid replacement. This is important for managing shock or significant blood loss, but it is not the first priority in managing severe bleeding.
B. Place the client's arm in a dependent position. This would not be appropriate for severe bleeding and does not control hemorrhage effectively.
C. Apply pressure directly to the wound. This is correct. Direct pressure is the immediate and essential step to control bleeding in a severe wound. It helps to stabilize the clot and reduce blood loss.
D. Apply a tourniquet just below the level of the shoulder. This is not the first intervention. A tourniquet is used if direct pressure does not control severe bleeding and should be applied above the wound, not below.

A. Hormone therapy decreases the risk of cardiovascular events. B. Hormone therapy may prevent osteoporotic fractures. C. Hormone therapy should be taken in doses throughout the day. D. If a dose is missed, then the next dose should be doubled.

Correct Answer is B

Explanation

A. Hormone therapy decreases the risk of cardiovascular events: This is incorrect. Hormone therapy has been associated with an increased risk of cardiovascular events, such as heart attacks and strokes, especially in older women or those with preexisting risk factors.
B. Hormone therapy may prevent osteoporotic fractures: This is correct. Hormone therapy can help maintain bone density and reduce the risk of osteoporotic fractures, which is beneficial after a total hysterectomy.
C. Hormone therapy should be taken in doses throughout the day: This is incorrect. Hormone therapy is typically taken in a single daily dose or according to a specific schedule, rather than multiple times throughout the day.
D. If a dose is missed, then the next dose should be doubled: This is incorrect. Missing a dose of hormone therapy should be addressed according to the specific medication instructions, and doubling the dose is not generally recommended.
