Question

Anaphylactic shock is the most severe form of systemic allergic reaction. Immunologically medicated substances are released into the blood, causing vasodilation and an increase in capillary permeability. What physiologic response often follows the vascular response in anaphylaxis?
a. Uterine smooth muscle reactionb. Laryngeal edemac. Broncodilationd. Gastrointestinal relaxation

Answer 1

Answer:

b. Laryngeal edema

Explanation

Laryngeal edema is a possible physiological response that will follow Anaphylactic shock. The Edema results to the decreased size of the laryngeal lumen.  

It presents as respiratory difficulty or post extubation stridor which is presence of inspiratory noise as a result of increased effort in breathing due to narrowing of the airway. Other symptoms include fainting and low blood pressure.
