A patient's assessment data present as follows: pH, 7.10; PaCO2, 60 mm Hg; PaO2, 40 mm Hg; HCO3, 24 mEq/L; RR, 34 breaths/min; HR, 128 beats/min; and BP, 180/92 mm Hg
This condition is best described as
a. uncompensated respiratory acidosis.
b. uncompensated metabolic acidosis.
c. compensated metabolic acidosis.
d. compensated respiratory acidosis.
A
The pH is below normal range (7.35-7.45), so this is uncompensated acidosis. The PaCO2 is markedly elevated, and the HCO3 is normal. This indicates uncompensated respiratory acidosis. Uncompensated respiratory acidosis values include a pH below 7.35, PACO2 above 45 mm Hg, and HCO3 of 22 to 26 mEq/L. Uncompensated metabolic acidosis values include a pH below 7.35, PACO2 of 35 to 45 mm Hg, and HCO3 above 22 mEq/L. Compensated metabolic acidosis values include a pH of 7.35 to 7.39, PACO2 below 35 mm Hg, and HCO3- below 22 mEq/L. Compensated respiratory acidosis values include a pH of 7.35 to 7.35, PACO2 above 45 mm Hg, and HCO3 above 26 mEq/L.
