- A. Administer prescribed emergency therapy and assess airway and breathing continuously
- B. Offer a large meal to prevent treatment-related weakness
- C. Place the patient flat and leave the room to obtain the chart

Explanation
Falling oxygen saturation indicates a breathing emergency, so prescribed emergency bronchodilator therapy, oxygen support and continuous assessment take priority. Lying flat and delaying treatment can worsen respiratory compromise.
