Which of the following is a potential complication of carbon monoxide poisoning?
Conversion to carbon monoxide.
Formation of carboxyhemoglobin.
Increased production of red blood cells.
Decreased pulmonary function.
The Correct Answer is B
Carbon monoxide binds to the haemoglobin to create a molecule called carboxyhemoglobin (COHb), which interferes with the body’s ability to transport and use oxygen, especially in the brain.
Choice A is incorrect because carbon monoxide poisoning occurs when carbon monoxide builds up in your bloodstream.
Choice C is incorrect because carbon monoxide poisoning does not increase the production of red blood cells.
Choice D is incorrect because decreased pulmonary function is not a potential complication of carbon monoxide poisoning.
