Which of the following phenomena would her care team most realistically anticipate? Her kidneys will adapt with an increase in plasma HCO3- and her pH will decrease.
Respiratory acidosis is accompanied by renal adaptation with a more marked increase in plasma HCO3- and a lesser decrease in pH. Her pH is likely below 7.35, and the likely renal response involves the reabsorption of HCO3- and secretion of H+. Excess CO2 production is not a common manifestation of obstructive lung disease.
A 68 year old woman with a new onset a vascular dementia has recently begun retaining urine. Which of the following physiological
