A nurse is caring for an older patient who is scheduled to be discharged following an admission for pneumonia. The nurse is collecting data and notes that the patient’s breathing is shallow, and his respiratory rate is 30/min. He tells the nurse that he is short of breath and his fingers are tingling. After notifying the provider, the nurse obtains ABG’s and the results are: pH 7.48, PaCO2 28 mm Hg, PaO2 85 mm Hg and HCO3 is 22 mEq/L. What imbalance is the patient exhibiting? Normal Values: pH: 7.35-7.45, PCO2: 35 mm Hg – 45 mm Hg, pO2: 75 mm Hg – 100 mmHg, HCO3: 22 mEq/L – 26 mEq/L, O2 saturation > 95%
