QUESTION: An electrode has a silver/silver chloride anode and a platinum wire cathode. It is
suspended in KCl solution and separated from the blood to be analyzed by a selectively
permeable membrane. Such an electrode is used to measure which of the following?
A. pH
B. PCO2
C. PO2
D. HCO3 - ANSWER-C. PO2
QUESTION: Which of these blood levels will decrease during intravascular hemolysis?

D. Haptoglobin - ANSWER-D. Haptoglobin
Haptoglobin is an alpha2-globulin that binds to free Hgb intravascularly. Increased intravascular
destruction of RBCs will result in a decrease in haptoglobin level.
QUESTION: All of the following are considered cutaneous porphyrias, EXCEPT?
A. Porphyria cutanea tarda
B. Acute intermittent porphyria
C. Congenital erythropoietic porphyria
D. Erythropoietic protoporphyria - ANSWER-B. Acute intermittent porphyria
Acute intermittent porphyria is a neurological porphyria. Porphyria cutanea tarda, Congenital
erythropoietic porphyria, and Erythropoietic protoporphyria are all cutaneous porphyrias.

A. Squamous
B. Cuboidal
C. Transitional
D. Flattened cells - ANSWER-D. Flattened cells
QUESTION: Which of the following cells are lining cells that could be seen in a peritoneal fluid?
A. Choroidal cells
B. Mesothelial cells
C. Ependymal cells
D. Squamous epithelial cells - ANSWER-B. Mesothelial cells
Mesothelial cells are lining cells of all serous cavities, so it's not uncommon to see them on a
differential for pleural, peritoneal, or pericardial fluid. Choroidal cells are part of the epithelial
lining of the choroid plexus. Ependymal cells are lining cells of the ventricles and neural canal.
