A 31-year-old client with a diagnosis of end-stage liver failure has been admitted to the intensive care unit of a hospital
Arterial blood sampling indicates that the man has an acid-base imbalance. Which of the following situations is most likely to result in an inappropriate pH?
A)
Conservation or formation of new HCO3- by the kidneys
B)
Low albumin and plasma globulin levels
C)
Transcompartmental exchange of H+ and potassium ions
D)
Renal excretion of HCO3- in the presence of excess base
Ans:
B
Feedback:
Albumin and plasma globulins are key protein buffers in the vascular compartment; consequently, a low albumin level, as is common in liver failure, is apt to result in acid-base imbalances. Answer choices A, C, and D all convey normal physiological processes that help to maintain pH.
