AEMT Pathophysiology with complete solutions 2024/2025

AEMT Pathophysiology Pathophysiology - correct answer Study of the effects and progression of disease and injury. Body is trying to maintain homeostasis. Clinical Impression - correct answer Made from studying signs (tangible, objectively observable results) and symptoms (patients subjective sensations.) Mechanisms of Disease and Injury - correct answer Hypoxia, nutritional imbalance, physical trauma, infection, toxins, and environment. Hypoxic Cellular Injury - correct answer Any time oxygen delivery or utilization to cells is disrupted. Normal human PaO2 (partial pressure of O2) is between 85 to 100 mmHg required for hemoglobin to be adequately saturated with oxygen molecules. Sodium/Potassium Pump - correct answer Maintains the electrolyte balance across cell membranes. Aerobic Metabolism - correct answer the cellular process in which oxygen is used to metabolize glucose. Energy is produced in an efficient manner with minimal waste products. Anaerobic Metabolism - correct answer The cellular process in which glucose is metabolized into energy without oxygen. Energy is produced in an inefficient manner with many waste products. Lactic Acid - correct answer An organic acid present in blood and muscle tissue as a product of the anaerobic metabolism of glucose and glycogen. Contributes to metabolic acidosis. Metabolic Acidosis - correct answer pH: Decreased PCO2: Decreased [HCO3-]: Decreased (*primary disturbance) Compensatory response: Hyperventilation Components of oxygen delivery - correct answer -Adequate onloading of o2 onto hemolgobin of RBC. -Circulation of RBC through microvasculature (cap. beds) to perfuse the tissue of the body. -Ade. offloading of O2 to tissues once RBC reach microvascu.
