196) ANSWER
C) pH 7.49; PaCO2 36; HCO3- 30; PaO2 90
RATIONALE
Clients who take potassium-wasting diuretics, such as Lasix, are at risk for developing hypokalemia and metabolic alkalosis. Options 1 and 2 are incorrect because they reflect an acidotic state. Option 1 is a respiratory acidosis and option 2 is a respiratory acidosis with partial compensation. Option 4 is incorrect because the primary disturbance is a respiratory alkalosis due to the increased PaCO2 level. Critical words are furosemide and potassium level of 3.2. Recognize the drug is a potassium-wasting diuretic that contributes to metabolic alkalosis. Determine that options 1 and 2 reflect acidosis, and eliminate them. Option 4 is respiratory in nature, so eliminate it.
