The nurse is aware that which of the following results when an increased concentration of hydrogen ions occurs within the body fluids?

Rationale: A. Retention of carbon dioxide can lead to acidosis, but it is not a direct result of increased hydrogen ions. B. An increased concentration of hydrogen ions (H⁺) lowers the pH of body fluids, making them acidic. C. Fluids become alkaline when hydrogen ion concentration is low, not high. D. Oxygen ions are not released as a response to hydrogen ion concentration changes.
