The nurse admits a patient with a high potassium level. The nurse recognizes this activates the body's sodium–potassium exchange leading to which physical symptom?
A) Dehydration
B) Water retention
C) Fatigue
D) Dizziness
B
Feedback:
If potassium levels are very high, the retention of sodium in exchange for potassium also leads to retention of water and a dilution of blood volume, which decreases potassium concentration. Dehydration is a lack of volume in the blood vessels, which can lead to dizziness. Fatigue is a symptom of anemia, which is associated with renal failure.
