Chickenpox/Shingles
Chickenpox/Shingles ( 24 Questions)
Complete Blood Count (CBC) is not useful in confirming the diagnosis of chickenpox. CBC provides information about the number and types of blood cells but is not specific to chickenpox diagnosis.
Stool culture is not relevant in confirming the diagnosis of chickenpox. Stool culture is used to identify gastrointestinal infections, and it is not associated with chickenpox.
Tzanck smear and viral culture from vesicle fluid are useful in confirming the diagnosis of chickenpox. Tzanck smear involves taking a sample from the vesicle and staining it to identify multinucleated giant cells, which are characteristic of varicella-zoster virus (VZV) infection. Viral culture involves growing the VZV in a lab to confirm the presence of the virus.
Urinalysis is not relevant in confirming the diagnosis of chickenpox. Urinalysis is used to assess kidney function and detect urinary tract infections, but it does not help in diagnosing chickenpox.
Choice A rationale:

Choice B rationale:
Stool culture is not relevant in confirming the diagnosis of chickenpox. Stool culture is used to identify gastrointestinal infections, and it is not associated with chickenpox.
Choice C rationale:
