One of the greatest considerations when managing an emergency situation is to assess the victim for shock. Shock occurs when the body’s natural circulation patterns are disturbed - and the results can be catastrophic. Which of the following are the 4 major types of shock?
Explanation
Answer: B - The 4 major types of shock are: Hypovolemic, obstructive, distributive and cardiogenic. Shock, also known as hypo (low) perfusion, results when the body’s natural hemodynamic flow is disturbed. Hypovolemic shock occurs when there isn’t enough volume, either due to the victim bleeding out, suffering from severe dehydration or hemorrhaging internally. Obstructive shock occurs when an occlusion, such as a blood clot, prevents natural perfusion of an area. Distributive shock is caused by overly dilated vessels failing to “distribute” their load properly and cardiogenic shock -- often seen after myocardial infarction -- occurs when the heart muscle is not pumping efficiently.
