A nurse is assisting with the care of a client who sustained severe carbon monoxide (CO) poisoning after being trapped in a burning building. Which of the following actions should the nurse take first?

Perform hourly neurological assessments on the client.

Administer oxygen to the client at 100%.

Institute seizure precautions for the client.!

Provide ondansetron IV to the client for nausea.

Answer and Explanation

The Correct Answer is B

A. Perform hourly neurological assessments on the client:
Important, but not the first action. Neurological symptoms may improve with oxygenation.

B. Administer oxygen to the client at 100%:
CO binds to hemoglobin with a higher affinity than oxygen. 100% oxygen displaces CO and is the priority intervention to reduce hypoxia.

C. Institute seizure precautions for the client:
Useful if the client becomes neurologically compromised, but not the priority over oxygenation.

D. Provide ondansetron IV to the client for nausea:
Nausea can occur in CO poisoning, but treating hypoxia is the priority.

Correct Answer is C

Explanation

A. Bright-red, moist lesions:
This describes superficial partial-thickness burns, not full-thickness burns.

B. Blackened, painful lesions:
Full-thickness burns may appear black (eschar), but they are typically painless due to nerve destruction.

C. Snowy white, painless lesions:
Full-thickness burns can be white, leathery, or charred and are often painless due to complete nerve damage.

D. Blistered, pinkish-white, painful lesions:
These are characteristic of deep partial-thickness burns, which retain some nerve sensation.

A. “Wash linens, clothes and towels.” B. “Dry clean all linens, towels, and clothes.” C. “Remove infested pets from the home.” D. “Discard infested mattresses.”

Correct Answer is A

Explanation

A. “Wash linens, clothes and towels.”
Scabies mites can survive for up to 2–3 days on fabrics. Washing items in hot water and drying on high heat effectively kills mites.

B. “Dry clean all linens, towels, and clothes.”
Not necessary; washing with hot water is sufficient and more accessible.

C. “Remove infested pets from the home.”
Scabies is species-specific. Human scabies mites do not live on pets.

D. “Discard infested mattresses.”
Mites cannot survive long on surfaces without human contact. Mattresses can be vacuumed and covered if needed.
