A patient is experiencing respiratory acidosis. Which organ system is responsible for compensation in this patient?

A) Renal
B) Endocrine
C) Respiratory
D) Gastrointestinal

The kidneys (renal) are responsible for respiratory acidosis compensation. A problem with the respiratory system causes respiratory acidosis, so another organ system (renal) needs to compensate. Problems with the gastrointestinal and endocrine systems can cause acid-base imbalances, but these systems cannot compensate for an existing imbalance.
