When assessing a client with suspected carbon monoxide poisoning, which finding would be least reliable?

Anna71 [15]

A cherry red complexion would be the least trustworthy result when evaluating a client who had carbon monoxide poisoning suspicions.

Carbon monoxide poisoning:

When present in sufficient quantity in the surrounding air, the odorless, colorless, and toxic gas known as carbon monoxide (CO) can result in rapid sickness and death. Using alternative fuels or electrical for warming, chilling, or cooking during power outages during situations like storms or winter storms can result in carbon monoxide(CO) buildup in a house, carport, or camper, which can harm the occupants and their pets.
It is never a good idea to use a generator, grill, camp stove, or any other appliance that burns fuel, kerosene, natural gas, or charcoal inside a house, basement, garage, camper, or even outside next to an apartment window or windows air conditioner.
Carbon monoxide poisoning can cause a variety of non-specific symptoms and indications. Migraine, vertigo, fatigue, vomiting, sickness, chest discomfort, and altered mental state are the most typical signs of CO poisoning.
