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.
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.

Correct Answer is ["C","E"]
Explanation
Choice A rationale: Diluting potassium elixir in juice is not a priority intervention for a critically elevated potassium level. Immediate actions are needed.
Choice B rationale: Monitoring intake and output is important, but it is not the highest priority when the potassium level is critically elevated.
Choice C rationale: Assessing the client for muscle weakness and flaccid paralysis is a high priority because hyperkalemia can lead to serious cardiac and neuromuscular complications.
Choice D rationale: Encouraging intake of orange juice or a banana may be appropriate for managing mild hypokalemia, but it is not the priority for a client with critically elevated potassium.
Choice E rationale: Obtaining a physician's order for cardiac monitoring is crucial, as hyperkalemia can lead to life-threatening cardiac dysrhythmias.
