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 A

Explanation

A. It divides the body into eight equal regions, with each region representing 12.5% of the total body surface area:
The Rule of Nines assigns percentages to major body parts (e.g., each leg = 18%, each arm = 9%, anterior torso = 18%) totaling 100%.

B. It divides the body into twelve equal regions, with each region representing 59% of the total body surface area:
Incorrect math and region count; total exceeds 100% and is not part of the rule of nines.

C. It divides the body into six equal regions, with each region representing 15% of the total body surface area:
Also incorrect; not consistent with the actual anatomic distribution used in the rule of nines.

D. It divides the body into nine equal regions, with each region representing 100% of the total body surface area:
Nonsensical; if each is 100%, total would be 900%, which is not accurate.
