________ is a management system designed to control personnel, facilities, equipment, and communications throughout an emergency operation

A 70-year-old man called 9-1-1 because of generalized weakness. When you arrive at the scene, you find the patient seated in his recliner. He is conscious and alert and is breathing without difficulty. Your physical exam reveals tenderness to his right upper abdominal quadrant, edema to his ankles, and distended jugular veins. The patient tells you that he takes Vasotec for hypertension and Maxide for his swollen ankles. His vital signs are stable. The MOST appropriate treatment for this patient includes:

A) an IV of D5W, 0.4 mg of sublingual nitroglycerin, ECG, and transport. B) high-flow oxygen, vascular access, 1 mg/kg of furosemide, and transport. C) oxygen, cardiac monitoring, an IV line at a keep-open rate, and transport. D) 12-lead ECG acquisition, vascular access, 4 mg of morphine, and transport.
