Pathophysiology (Western Governors University) STUDY QUESTIONS WITH CORRECT ANSWERS

A patient with a viral illness and severe vomiting has an elevated CO2 level and a blood pH of 7.53. She is breathing slowly. What condition does the patient have? Metabolic alkalosis Respiratory acidosis Metabolic acidosis Respiratory alkalosis What happens in a dehydrated patient? ADH levels decrease and the RAAS is inactivated. ADH levels increase and the RAAS is inactivated. ADH levels increase and the RAAS is activated. ADH levels decrease and the RAAS is activated. ACE (angiotensin converting enzymes) inhibitors are used to treat abnormal blood pressure. They prevent the conversion of angiotensin I to angiotensin II. Which explains how ACE inhibitors work? The decrease in the production of angiotensin II keeps blood vessels more dilated. This raises blood pressure. The decrease in the production of angiotensin II constricts blood vessels. This raises blood pressure. The decrease in the production of angiotensin II constricts blood vessels. This lowers blood pressure. The decrease in the production of angiotensin II keeps blood vessels more dilated. This lowers blood pressure. In diabetic ketoacidosis, what happens to the anion gap? Because HCO3- is consumed, the anion gap increases. Because extra HCO3- is produced, the anion gap decreases. Because HCO3- is consumed, the anion gap decreases. Because extra HCO3- is produced, the anion gap increases.
