Case #3. Emma Siss, a 21-year-old woman, returns to the emergency room for the fifth time. She has been repeatedly treated for bulimia. You note slow, deep breathing. ARTERIAL BLOOD GASES are as follows: (write high, low, or normal beside each value) pH = 7.45 pCO, = 47 mmHg HCO, 33 mEq/L %3D a) Determine the primary acid-base problem: respiratory acidosis respiratory alkalosis metabolic acidosis metabolic alkalosis b) What type of compensation is occurring, if any? respiratory hypoventilation respiratory hyperventilation no compensation is occurring Case #4. Sin Coapy has been admitted to the ER after passing out during an A & P exam. Prior to the exam, his classmates noticed that he was hyperventilating and expressed his nervousness for the exam, for which he did not study. ARTERIAL BLOOD GASES are as follows: (write high, low, or normal beside each value) pH = 7.50 pCO, = 29 mmHg HCO. 24 mEq/L a) Determine the primary acid-base problem: respiratory acidosis respiratory alkalosis metabolic acidosis metabolic alkalosis b) Is the patient compensating for the problem? Yes No c) Hyperventilation contributed to the pH imbalance because... He breathed out excess CO2, causing his blood pH to change He trapped excess CO2 in his lungs, causing his blood pH to change d) How would breathing into a brown paper bag help him? He would be breathing extra 02, which would correct his blood pH He would be rebreathing C02, which would increase his pC02 He would be breathing out excess CO2, which would correct his blood pH
