The nurse is caring for a client injured in a house fire. Which one of the following findings suggests carbon monoxide poisoning? A. Wheezing respirations B. "Cherry red" skin C. Gastric ulceration D. "Burgundy" colored urine

Carbon monoxide poisoning is caused by inhaling high levels of carbon monoxide (CO) gas. The most common symptoms of CO poisoning include headache, dizziness, weakness, vomiting, chest pain, and confusion. Severe cases can lead to altered mental state, loss of consciousness, seizures, and even death.

Now, let's analyze each option: A. Wheezing respirations: Wheezing is a high-pitched whistling sound made while breathing. It is often associated with asthma or other respiratory conditions but not with CO poisoning specifically. B. "Cherry red" skin: In carbon monoxide poisoning, CO binds with hemoglobin in the blood to form carboxyhemoglobin causing a "cherry red" color on the skin. This is a distinctive feature of CO poisoning. C. Gastric ulceration: Gastric ulcers are sores that develop in the lining of the stomach, and they are not directly related to CO poisoning. D. "Burgundy" colored urine: Dark, concentrated, or burgundy-colored urine can indicate dehydration, some medications, or other medical conditions, but it is not a specific symptom of CO poisoning.

Based on our analysis, Option B, "Cherry red" skin, is the most indicative symptom of carbon monoxide poisoning among the given choices. Therefore, the correct answer is B.
