When analyzing an arterial blood gas report of a client with COPD and respiratory acidosis, the nurse anticipates that compensation will develop through which of the following mechanisms?
1. The kidneys retain bicarbonate.
2. The kidneys excrete bicarbonate.
3. The lungs will retain carbon dioxide.
4. The lungs will excrete carbon dioxide.
The kidneys retain bicarbonate.
Rationale: The kidneys will compensate for a respiratory disorder by retaining bicarbonate. Excreting bicarbonate causes acidosis to develop. Retaining carbon dioxide causes respiratory acidosis. Excreting carbon dioxide causes respiratory alkalosis.
