A nurse is evaluating a client's SaO2; which manifestation requires follow-up because the SaO2 is below the expected reference range?

Explanation:
Low arterial oxygen saturation means the blood isn’t carrying as much oxygen as it should, so the body often responds with increased breathing effort and a sensation of breathlessness. Dyspnea is the manifestation that most directly indicates possible hypoxemia and therefore needs follow-up to assess oxygenation and intervene if needed. Normal breathing (eupnea) and a heart rate of 84/min are not indicators of low SaO2 by themselves, and an SaO2 of 96% is within the normal reference range, so they don’t signal a need for further action.
