A 2-day-old neonate becomes lethargic and uninterested in breast-feeding. Physical examination reveals tachypnea with a normal heart rate and breath sounds. Initial blood chemistry values include normal glucose, sodium, potassium, chloride, and bicarbonate (HCO3–) levels; initial blood gas values reveal a pH of 7.53, partial pressure of oxygen (PO2) of 103 mmHg, and partial pressure of carbon dioxide (PCO2) of 27 mmHg. Which of the following is the most appropriate treatment?

A. Administer acid to treat metabolic alkalosis
B. Administer alkali to treat metabolic acidosis
C. Administer alkali to treat respiratory acidosis
D. Decrease the respiratory rate to treat metabolic acidosis
E. Decrease the respiratory rate to treat respiratory alkalosis
