Final answer:
A patient with confusion and cherry red skin is most likely experiencing symptoms of carbon monoxide poisoning.
Step-by-step explanation:
A patient with confusion and cherry red skin is most likely experiencing symptoms of carbon monoxide poisoning. Carbon monoxide has a greater affinity for hemoglobin than oxygen, preventing oxygen from binding to hemoglobin and resulting in decreased oxygen transportation through the body. Symptoms of carbon monoxide poisoning often include headache, dizziness, weakness, vomiting, chest pain, and confusion.
