Microscopic examination of stools for fecal cells provides preliminary information as to the cause of diarrhea because:
A) Neutrophils are present in conditions caused by toxin-producing bacteria
B) Neutrophils are present in conditions that affect the intestinal wall
C) Red and white blood cells are present if the cause is malabsorption
D) Neutrophils are present if the condition is of nonbacterial etiology

Question

Quizplus · Accepted Answer

The presence of neutrophils in fecal cells indicates inflammation in the intestinal wall, which is commonly seen in conditions causing diarrhea. Toxin-producing bacteria may also cause inflammation, but this is a secondary effect rather than the primary cause. Malabsorption may result in the presence of red and white blood cells, but this is not specific to malabsorption and may also occur in other conditions. Neutrophils may or may not be present in nonbacterial etiologies, so option D is less specific.
