Which assessment is a nursing priority to prevent complications in clients with respiratory acidosis?

• A. Observing the nail beds
• B. Listening to breath sounds
• C. Monitoring breathing status
• D. Checking muscle contractions

Answer: (C)

Monitoring breathing status is the most important nursing action to prevent complications in respiratory acidosis. This condition stems from inadequate ventilation that allows CO2 to build up, causing acidemia and increasing the risk of hypoxemia and respiratory failure. By continuously assessing how the patient is ventilating—rate, depth, effort, and use of accessory muscles—and how well gas exchange is occurring (through oxygen saturation and, when available, capnography or ABG trends), the nurse can spot early signs of deterioration and escalate care promptly. This focused monitoring guides interventions to improve ventilation and gas exchange, such as positioning, airway support, and appropriate therapies as ordered. Observing nail beds or listening to breath sounds provides helpful information, but they don’t offer a comprehensive, ongoing picture of ventilation status needed to prevent complications. Checking muscle contractions, while useful in other contexts, doesn’t directly address the ventilation and gas exchange priorities in this scenario.
