Question

Your patient is experiencing an allergic reaction to a bee sting, causing a natural release of histamine and other mediators by the body. What will the release of histamine and the mediators do for the patient?

A) Hypotension and bronchospasm
B) Bronchodilation and hives
C) Bradycardia and hypertension
D) Tachycardia and lacrimation

Answer 1

During an allergic reaction, the release of histamine and other mediators can cause various symptoms such as runny nose, watery eyes, itching, difficulty breathing, hives, and hypotension.

Step-by-step explanation:

The release of histamine and other mediators during an allergic reaction can cause a range of symptoms in the patient. Histamine stimulates mucus secretion in the nasal passages and tear formation, leading to a runny nose and watery eyes. It also causes itching, sneezing, and bronchoconstriction, resulting in difficulty breathing and coughing. Additionally, histamine can cause vasodilation, which can lead to hives, hypotension (low blood pressure), and in severe cases, anaphylaxis.
