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.

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
The concentration of solute particles in the solution is the primary factor that determines the movement of water across cell membranes in osmosis.
Hydrostatic pressure (choice A) can affect the movement of water across cell membranes but is not the primary factor responsible for osmosis.
Temperature (choice C) can affect the rate of osmosis but is not the primary factor responsible for osmosis.
Kinetic energy of liquid water molecules (choice D) can affect the rate of osmosis but is not the primary factor responsible for osmosis.
