PN3 Exam 3 Study Guide

Exam 3 Study Guide Shock Syndromes: Shock is a systemic condition where there is an imbalance between the oxygen supply to the tissues/organs and the oxygen needs of those tissues/organs. There are different types of shock. Any situation that decreases vascular volume, blood pressure, or cardiac function can lead to shock. Shock can be divided according to the cause. There are three main types of shock. Distributive shock is further divided into another three categories. Cardiogenic: pump (heart) failure Hypovolemic: lack of circulating volume in the vascular space Distributive: alteration in the vascular bed size ● Neurogenic: impaired sympathetic nervous system ● Anaphylactic: hypersensitivity response due to antigen-antibody reaction ● Septic: Due to systemic infection Complications of each type ● Multiple Organ Dysfunction Syndrome (MODS) ● Disseminated Intravascular Coagulation (DIC) ● Acute respiratory Distress Syndrome (ARDS) Treatment goals of each type ● Identify and treat the underlying cause ● Deliver oxygen to the tissues ● Maintain Circulation ● Monitor for complications ● Provide comfort and emotional support 4 stages of shock: ● Initial: decreased CO and impaired tissue perfusion ● Compensatory: activation of sympathetic nervous system (SNS) ● Progressive: every system in the body is affected and MOD happens ● Refractory: body will no longer respond to therapy SIRS is a clinical response to a nonspecific insult. Regardless of the et
