Final answer:
Administer an epinephrine shot as the first action when treating a 9-year-old patient with respiratory distress, hives, stridorous breath sounds, and a fast heart rate after a bee sting.
Step-by-step explanation:
The first action you should take when treating a 9-year-old patient experiencing respiratory distress, hives, stridorous breath sounds, and a fast heart rate after being stung by a bee is to administer an epinephrine shot. This is because the symptoms described suggest an anaphylactic reaction, which is a severe allergic reaction that can be life-threatening. Epinephrine helps control the immune reaction, constricts blood vessels to increase blood pressure, relaxes smooth muscles in the lungs to improve breathing, and reduces swelling that may block the airways.
