Question 1

Which type of necrosis is characteristic of liquefactive destruction seen in brain infarcts?

Which fungal organism, commonly found in soil and pigeon droppings, can produce meningitis in immunocompromised decedents and poses a respiratory risk during embalming?

Accepted Answer

Cryptococcus neoformans

Cryptococcus neoformans causes cryptococcal meningitis in immunocompromised individuals and its capsular antigens can be aerosolized during autopsy procedures.

Question 4

When embalming a body positive for HIV, the primary route of occupational transmission risk for the embalmer is:

Accepted Answer

Percutaneous injury (needlestick or sharps cut)

Answer

Percutaneous injury (needlestick or sharps wounds) is the primary documented route of occupational HIV transmission in healthcare and mortuary settings.

Question 5

Rigor mortis occurs due to which biochemical change in muscle tissue?
