ExhibitsA nurse is reviewing the medical record of a client who has COPD. The nurse should notify the provider about which of the following findings? (Click on the exhibit tabs for additional information about the client. There are three tabs that contain separate categories of data.)

Rationale: A. SpO₂: Although 88% is low for the general population, it is often an acceptable baseline for clients with COPD. Their oxygen saturation targets are typically between 88–92% to avoid suppressing respiratory drive, so this value may not require immediate provider notification. B. pH: A pH of 7.22 indicates respiratory acidosis, which is a serious and potentially life-threatening complication of COPD. This level of acidosis shows that the client’s ventilation is inadequate, and immediate intervention is needed. This is the most critical finding that requires provider notification. C. Respiratory rate: A rate of 22 breaths/min is slightly elevated but not critical. It may be compensatory and expected in a COPD patient who is hypoxic or retaining CO₂. By itself, it doesn't warrant urgent notification unless it worsens. D. Temperature: A temperature of 37.2°C (99°F) is within the normal range and does not indicate infection or acute illness. It is not a finding that necessitates notifying the provider at this point.
