The nurse has received a change of shift report on assigned clients. Which client would the nurse assess first?

A. A client with pleural effusion who reports an increase of coughing with pleuritic pain 4/10: While the client is experiencing discomfort, the pain and cough are moderate and not immediately life-threatening. Assessment should follow clients with acute respiratory compromise. B. A client with cor pulmonale with a PaO2 of 78 mmHg who is being discharged home on oxygen: A PaO2 of 78 mmHg indicates mild hypoxemia but is generally stable for a client ready for discharge. This client does not require immediate assessment compared with those with sudden respiratory deterioration. C. A client with COVID-19 with acute onset of worsening dyspnea: Acute worsening dyspnea indicates potential respiratory failure or hypoxemia and is immediately life-threatening. Prompt assessment and intervention are critical to prevent rapid deterioration, making this the priority client. D. A client with acute respiratory distress syndrome (ARDS) who is scheduled for prone positioning: While ARDS requires careful monitoring, the scheduled prone positioning is a planned intervention and the client is likely stable prior to the procedure. Immediate assessment is less urgent than for sudden respiratory compromise.
