Question

a 27 - year - old female patient presents with a staphylococcus aureus infection. which of the following wbcs will be elevated?
a) lymphocytes
b) monocytes
c) eosinophils
d) neutrophils

Explanation:

Neutrophils are the first - responders to bacterial infections like staphylococcus aureus. They phagocytose (engulf and destroy) the bacteria. Lymphocytes are mainly involved in adaptive immunity against viruses and some bacteria in a more long - term response. Monocytes are involved in phagocytosis and antigen - presentation but are not the primary cells for acute bacterial infections. Eosinophils are mainly associated with parasitic infections and allergic reactions.

Answer:

d) neutrophils
