Intro Medical-Surgical Nursing by Timby & Smith: Ch 17 Caring for Clients in Shock Hypoxia and Anaerobic Metabolism, Neuroendocrine Regulation (ACTH, ADH, Corticosteroid Hormones, Catecholamines), Cardiac Output and Perfusion Dynamics, Classification of Shock States (Hypovolemic, Cardiogenic, Distributive, Neurogenic, Obstructive, Septic), Stages of Shock Progression (Compensation, Decompensation, Irreversible), Systemic Inflammatory Response Syndrome (SIRS) Criteria, Endotoxin-Mediated Septic Shock, Multiple Organ Dysfunction Syndrome (MODS), Clinical Manifestations and Hemodynamic Changes, Fluid Volume Loss Stratification (Stages I–IV Hypovolemic Shock), and Pharmacologic Management Exam Questions Verified and Provided with A+ Graded Rationales Latest Updated 2026 adensoine triposphate (ATP) energy source for operating sodium and potassium pumps on cellular membrane Adrenocorticotropic hormone (ACTH) substance secreted by the pituitary that stimulates the adrenal glands to secrete corticosteroid hormones anaerobic metabolism inefficient mechanism for meeting energy requirements used when the amount of oxygen reaching the cells decreases anaphylactic shock severe allergic reaction that occurs after exposure to a substance to which a person is extremely sensitive antidiuretic hormone (ADH) substance secreted by the pituitary in response to low blood volume that promotes reabsorption of water that the kidneys would ordinarily excrete cardiac output volume of blood ejected from the left ventricle per minute cardiogenic shock shock that occurs when contraction of the heart is ineffective and cardiac output is reduced catecholamines neurotransmitters that stimulate responses by the sympathetic nervous system compensation stage first stage of shock, during which several physiologic mechanisms attempt to stabilize the spiraling consequences of shock corticosteroid hormones chemicals secreted by the adrenal cortex decompensation stage stage in shock that occurs as compensatory mechanisms fail and the client's condition spirals downward into cellular hypoxia, coagulation defects, and cardiovascular changes distributive shock shock that occurs when fluid in the circulatory system does not facilitate effective perfusion of the tissue; sometimes called normovolemic shock endotoxins harmful chemicals released from within a bacterial cell; probably the major cause of toxic shock hypovolemic shock condition that occurs when the volume of extracellular fluid is significantly diminished, primarily because of loss or reduction in blood or plasma hypoxia decrease in the amount of oxygen reaching the cells irreversible stage stage in shock that occurs when significant numbers of cells and organ systems become damaged and the client no longer responds to medical interventions ischemia impaired oxygenation of cells and tissues Multiple Organ Dysfunction Syndrome (MODS) complication of overwhelming inflammation that results in massive cellular, tissue, and organ injury neurogenic shock shock that results from an insult
