A patient experiencing an asthma attack should be positioned in an upright position.

You are transporting a child with a small laceration to his leg, sustained after cutting himself of a piece of broken glass. During transport, you observe a pulse oximeter reading of 87% on the frantic, crying, and actively moving child. The child is alert and oriented with a normal pulse and respiratory rate with pink skin that is warm to touch. Your immediate action would be to:

A) start positive pressure ventilation with supplemental oxygen. B) attempt to calm the child and obtain another SpO2 reading. C) apply high-concentration oxygen via nonrebreather. D) check the laceration for uncontrolled bleeding.

Your 68-year-old patient is in cardiac arrest. His wife states that he was working in the yard and just slumped over. What should you suspect is the cause of his cardiac arrest?

A) A pulseless ventricular rhythm B) Anaphylaxis from a bee sting C) Respiratory arrest D) Diabetic ketoacidosis
