Questions: Which of the following blood conditions is NOT correctly matched to its description? A) Leukopenia = abnormally low white blood count commonly induced by drugs, glucocorticoids, and anti-cancer agents B) Leukocytosis = white blood cell counts greater than 11,000 cells/mm^3 C) Infectious mononucleosis = "kissing disease" caused by Epstein Barr virus resulting in excessive numbers of atypical monocytes D) Acute leukemia = a slow advancing form of cancer that produces large number of immature myeloblast stages of white blood cells E) All of the above conditions are correctly matched to their descriptions

The answer is D) Acute leukemia = a slow advancing form of cancer that produces large number of immature myeloblast stages of white blood cells.

Explanation for each option:

A) Leukopenia = abnormally low white blood count commonly induced by drugs, glucocorticoids, and anti-cancer agents

• This is correct. Leukopenia refers to a decrease in the number of white blood cells, which can indeed be caused by certain medications and treatments.

B) Leukocytosis = white blood cell counts greater than 11,000 cells/mm³

• This is correct. Leukocytosis is defined as an increase in the number of white blood cells, typically above 11,000 cells/mm³.

C) Infectious mononucleosis = "kissing disease" caused by Epstein Barr virus resulting in excessive numbers of atypical monocytes

• This is correct. Infectious mononucleosis is often referred to as the "kissing disease" and is caused by the Epstein-Barr virus, leading to an increase in atypical monocytes.

D) Acute leukemia = a slow advancing form of cancer that produces large number of immature myeloblast stages of white blood cells

• This is incorrect. Acute leukemia is characterized by a rapid progression and the production of a large number of immature white blood cells, not a slow advancement.

E) All of the above conditions are correctly matched to their descriptions

• This is incorrect because option D is not correctly matched.

In summary, option D is the condition that is not correctly matched to its description.
