Answer to Question 1

Answer: B, E
In metabolic alkalosis, the blood pH will be greater than 7.45 and the bicarbonate level greater than 28 mEq/L. The ECG pattern shows changes similar to those seen with hypokalemia. Serum glucose level is not used to confirm the diagnosis of metabolic alkalosis. The presence of kidney stones is not associated with the development of metabolic alkalosis. The presence of bilateral lower lobe infiltrates on chest x-ray would not contribute to the development of metabolic alkalosis. This finding might be the result of metabolic alkalosis if the client's respiratory status is compromised.

Answer to Question 2

Answer: A, B, D

Respiratory compensation for metabolic alkalosis depresses the respiratory rate and reduces the depth of breathing to promote carbon dioxide retention. The depressed respiratory drive associated with metabolic alkalosis can lead to hypoxemia and impaired oxygenation of tissues. Oxygen saturation levels of less than 90 indicate significant oxygenation problems. Changes in mental status or behavior may be early signs of hypoxia. Urine output less than 30 mL/hr would indicate Fluid Volume Deficit. Weight is used as an indicator of fluid balance. A rapid weight change would indicate Fluid Volume Deficit.
