What roles do the lungs and kidneys play in regulating acid-base balance? o The lungs regulate acid-base balance by adjusting the level of carbon dioxide (CO2) through ventilation; increased breathing removes CO2 (alkalosis), while decreased ventilation retains CO2 (acidosis). o The kidneys contribute by reabsorbing bicarbonate (HCO3−) and excreting hydrogen ions (H+), helping to buffer and maintain pH over hours to days.2 2. How are respiratory and metabolic acidosis different in terms of cause and compensation? o Respiratory acidosis is caused by impaired gas exchange or hypoventilation, leading to CO2 retention; compensation occurs via increased renal excretion of H+ and reabsorption of HCO3−. o Metabolic acidosis results from excess acids (e.g., DKA) or loss of bicarbonate; the lungs compensate by hyperventilating to blow off CO2, reducing acid levels. 3. What symptoms and lab findings are typical of metabolic alkalosis? o Symptoms include muscle twitching, confusion, tetany, respiratory depression, and nausea. o Lab findings show pH 7.45, elevated bicarbonate (HCO3−), and may have hypokalemia. The PaCO2 may be elevated as compensation (hypoventilation). 4. What are the nursing priorities for a client with respiratory acidosis? o Assess respiratory status frequently, monitor ABGs, ensure airway patency, support ventilation (possibly with mech
