Step-by-step explanation:
The 'Look, Listen, Feel' approach is primarily used during a secondary assessment in medical care to evaluate Observing, listening for breath sounds, and feeling for chest movement option (C). This involves observing the patient for any signs of breathing difficulties, listening for abnormal breath sounds, and feeling for chest movement. By using this approach, healthcare providers can gather important information about a patient's respiratory function.
Collectively, the "Look, Listen, Feel" approach allows healthcare professionals to gather essential information about a patient's respiratory status, aiding in the overall assessment and subsequent care.
