Mrs. Kalen is a 70-year-old female who has arrived at the ER due to persistent vomiting for two days now. She appears to be lethargic and weak and has myalgia. She is noted to have dry mucus membranes and her capillary refill takes >4 seconds. She is diagnosed as having gastroenteritis and dehydration. Measurement of arterial blood gas shows pH 7.5, PaO2 85 mm Hg, PaCO2 40 mm Hg, and HCO3 34 mmol/L. Based on the acid-base interruption from Mrs. Kalen, what can the nurse anticipate the treatment will be for correcting this imbalance?
