General Pathology Board Review Darby 8th

Cellular injury may be caused by all of the following except one. Which one is the exception?

• infections

• chemical agents

• mitosis

• tissue necrosis

A protective response of the body designed to rid the initial cause and consequences of cell injury explains.

• inflammation

• regeneration

• angiogenesis

• autoimmune response

Inflammation consists of vascular responses, migration and activation of white blood cells, and systemic reactions. It is present during cellular injury and wound repair.

• both true

• both false

• first true, second false

• first false, second true

Mr. Smith presents with generalized gingivitis with swelling, bleeding, and redness. The redness (rubor) is caused by:

• vasoconstriction of blood vessels

• increased vascularity

• stretching of pain receptors

• exudation of fluid

Mr. Smith's gingival swelling is caused by:

• vasoconstriction of blood vessels

• increased vacularity

• stretching of pain receptors

• exudation of fluid

Increased blood flow and the release of inflammatory mediators cause which cardinal sign of inflammation?

• rubor

• calor

• dolor

• functio laesa

Acute inflammation is characterized by a sustained inflammatory response. It is manifested by the exudation of fluid and plasma proteins and the emigration of leukocytes, most notably neutrophils.

• both true

• both false

• first true, second false

• first false, second true

What is the first white blood cell to emigrate to the site of injury?

• monocyte

• neutrophil

• eosinophil

• macrophage

Macrophages, lymphocytes, and eosinophils are all involved in the immune response. Neutrophils are involved in acute inflammation and not the immune response.

• both true

• both false

• first true, second false

• first false, seond true

Which white blood cell produces potent vasoconstrictive mediators?

• neutrophil

• macrophage

• lymphocyte

• eosinophil
