- Assessing vital signs and oxygen saturation: Restlessness, dyspnea, and crackles in the lung bases are signs of respiratory distress. The nurse should check the client's vital signs, including heart rate, respiratory rate, blood pressure, and oxygen saturation, to monitor the severity of the client's condition.
Assessing the client's vital signs and oxygen saturation will provide crucial information about the client's respiratory status and guide further interventions.
