If the pH is elevated, what would you expect the potassium (K+) level to be?

• A. Elevated
• B. Normal
• C. Down
• D. Unpredictable

Answer: (C)

When the pH is elevated, it indicates a state of alkalosis in the body. In this situation, potassium ions have a tendency to shift from the extracellular fluid into the cells in an attempt to maintain acid-base balance. This shift results in a decrease in the amount of potassium circulating in the bloodstream, which would lead to a lower potassium level. Thus, in the context of elevated pH, it is expected that the potassium level would decrease due to this intracellular shifting. This physiological response aligns with the body's mechanisms to compensate for changes in pH.
