Question

a cbc of a 19 - year - old male patient shows elevated wbcs and neutrophils. this most likely indicates what?
a) cancer
b) bacterial infection
c) viral infection
d) parasitic infection

Explanation:

White blood cells (WBCs) are part of the immune system. Neutrophils are a type of WBC. Elevated WBCs and neutrophils are a common sign of a bacterial infection. In a bacterial infection, the body produces more neutrophils to fight the bacteria. Cancer can sometimes cause changes in blood cell counts, but it is not the most likely cause here. Viral infections often cause a different pattern in blood cell counts (e.g., sometimes lymphocytes are more affected). Parasitic infections may cause eosinophil elevation more commonly than neutrophil and general WBC elevation.

Answer:

B. Bacterial infection
