The nurse understands that the major factor affecting oxygenation in a client who has fluid in the lungs is:

poor tissue perfusion from circulatory insufficiency.

decreased diffusion of oxygen from the alveoli to the blood.

lowered oxygen carrying capacity.

decreased concentration of oxygen in the air.

Answer and Explanation

The Correct Answer is B

Choice A rationale: Poor tissue perfusion from circulatory insufficiency can affect oxygenation, but fluid in the lungs primarily impacts gas exchange at the alveolar level.

Choice B rationale: Decreased diffusion of oxygen from the alveoli to the blood is a major factor affecting oxygenation when fluid is present in the lungs.

Choice C rationale: Lowered oxygen carrying capacity can affect oxygenation but is not the primary concern in the presence of fluid in the lungs.

Choice D rationale: Decreased concentration of oxygen in the air is not the primary factor affecting oxygenation in a client with fluid in the lungs.
