Respiratory acidosis Correct Answer: pH low, PaCO2 high, K+ high. compensated by HCO3 high to bring pH to normal Metabolic acidosis Correct Answer: pH low, HCO3 low, K+ high compensated by PaCO2 lo... w Respiratory alkalosis Correct Answer: pH high, PaCO2 low, K+ low. compensated by HCO3 low to bring pH to normal Metabolic alkalosis Correct Answer: pH high, HCO3 high, K+ low compensated by PaCO2 high Buffer system Correct Answer: CO2 + H2O = H2CO3 = H(+) + HCO3 What causes Metabolic alkalosis? Correct Answer: loss of hydrogen ions or acids or an excess of base bicarbonate For example: -hypovolemia, -the loss of gastric fluid via NG suction or vomitting, -excessive bicarbonate intake, -massive transfusion of whole blood, -hyperaldosteronism. The nurse reviews the arterial blood gas results of a client and notes the following: pH 7.45, Paco2 of 30 mm Hg (30 mm Hg), and HCO3- of 20 mEq/L (20 mmol/L). The nurse analyzes these results as indicating which condition? Correct Answer: Respiratory alkalosis, compensated The nurse is caring for a client with a nasogastric tube that is attached to low suction. The nurse monitors the client for manifestations of which disorder that the client is at risk for? Correct Answer: Metabolic alkalosis A client with a 3-day history of nausea and vomiting presents to the emergency department. The client is hypoventilating and has a respiratory rate of 10 breaths/minute. The electrocardiogram (ECG) monitor displays tachycardia, with a heart rate of 120 beats/minute.
