ATI Chapter 46 Review: Advanced Med-Surg – Acid-Base Imbalances

In this Advanced Med-Surg episode, we review ATI Chapter 46, which focuses on acid-base imbalances and how the body maintains physiologic homeostasis through chemical, respiratory, and renal buffering systems. We’ll break down the mechanisms of compensation, explaining how the lungs regulate carbon dioxide and how the kidneys manage bicarbonate to stabilize arterial pH. The episode reviews the four primary acid-base disorders—respiratory acidosis, respiratory alkalosis, metabolic acidosis, and metabolic alkalosis—highlighting their causes, clinical manifestations, and priority nursing interventions. You’ll also hear a step-by-step approach to interpreting arterial blood gas results to accurately identify each imbalance. Potential complications, including respiratory arrest, dysrhythmias, and altered level of consciousness, are emphasized throughout. This episode provides an exam-ready framework to help nursing students assess, monitor, and manage acid-base disturbances safely and effectively.Source: All information in this podcast is based on ATI Advanced Medical-Surgical Nursing, Chapter 46
