(7 of 13)En RouteEMS is dispatched at 0815 to a home for a 3-year-old child with altered mental status. Call was made by the patient’s parent, who reports that the child had a high fever overnight and vomited several times. Outside temp is 32° F, skies are cloudy, roads are dry, and traffic is light. Ambulance is staffed with 2 paramedics; and a fire engine with EMTs is also responding.SceneYou arrive on location, PPE is donned and patient care equipment is being brought in by the fire engine personnel. Upon patient access, you find secretions obstructing the airway. After suctioning, patient has RR 10, shallow, SpO₂ 70%, EtCO₂ 68, absent gag reflex.BVM ventilations are in progress.During the “D” (Disability) phase of the primary assessment, which of these would be most helpful to assess to differentiate a cause of the patient’s condition?Select 2 options

Skin is pale and cool.During assessment, the patient becomes increasingly lethargic, gag reflex still intact. Vital signs: BP 92/60, HR 101, RR 24, SpO₂ 95% on room air, BGL 48 mg/dL.The paramedic prepares to administer oral glucose and confirms the patient’s identity by checking the medication label. Which “right” of medication administration does this best demonstrate?

Post Scene 12-lead shows signs of ischemia. The patient becomes more alert after glucose administration, but now reports a sensation of constant “chest pressure.” During transport, the patient suddenly becomes unresponsive and pulseless. ECG rhythm persists below:image.png        There are two drugs indicated for this resuscitation. While they can be given very close together during a well coordinated team resuscitation, one drug should be delivered before the other. Determine the two drugs to give and the order of priority they should be delivered below:
