Question Of The Day: Gastrointestinal Disorders

Q. Which of the following laboratory findings are expected when a client has diverticulitis?

A. Elevated red blood cell count.

B. Decreased platelet count.

C. Elevated white blood cell count.

D. Elevated serum blood urea nitrogen concentration.

Correct Answer: C

Explanation: Because of the inflammatory nature of diverticulitis, the nurse would anticipate an elevated white blood cell count. The remaining laboratory findings are not associated with diverticulitis. Elevated red blood cell counts occur in clients with polycythemia vera or fluid volume deficit. Decreased platelet counts can occur as a result of aplastic anemias or malignant blood disorders, as an adverse effect of some drugs, and as a result of some heritable conditions. Elevated serum blood urea nitrogen concentration is usually associated with renal conditions.
