The health care providers will be assessing this client for which of the following physiological events? Select all that apply.
A) Cerebral infarction
B) Coagulation necrosis
C) Rapid phagocytosis
D) Protein p53 deficiency
Ans: A, B
Feedback:
Tissue infarction is caused by prolonged oxygen deprivation, and the resulting large group of dead cells coagulates in the damaged area. During coagulation necrosis, acidosis develops and denatures the enzymatic and structural proteins of the cell. Phagocytosis occurs rapidly during apoptosis, so it does not elicit an inflammatory response. Protein p53 activation initiates apoptosis.
