Pathophysiology Exam 1 Rasmussen
Questions and Verified Detailed Answers
Pathophysiology - ✔✔The study of abnormalities in physiologic functioning of
living beings
Etiology - ✔✔The study of the causes and origins of disease
Pathogenesis - ✔✔Development or evolution of a disease
Allostasis - ✔✔Ability to achieve stability through change
Allostatic load - ✔✔The long-term negative impact of the stress response on the
body
Allostatic overload - ✔✔Over activation of adaptive systems -Highly
individualized
Primary level of prevention - ✔✔Altering susceptibility; reducing exposure for
susceptible persons
Examples of primary level of prevention - ✔✔Ex- Immunization, health/sex ed,
quit smoking drinking or poor diet.
Secondary level of prevention - ✔✔Conduction activities that help prevent a
worsening health status by detection or management of diseases

, Examples of secondary level of prevention - ✔✔Self breast exams, yearly cancer
screenings, proper management of diabetes
Changes with flight or fight reaction - ✔✔o HR, impulse speed and contractility
of heart- increases
o Relaxes bronchial smooth muscle to dilate airway
o BP increases
o Dilates pupils
o Promotes arousal, attention, and vigilance
3 stages of adaptation (GAS) - ✔✔Alarm reaction, stage of resistance, stage of
exhaustion
Alarm stage - ✔✔fight or flight response
reduced resistance to stressors
release catecholamines (epinephrine and norepinephrine) and adrenocortical
steroids (cortisol and aldosterone)
Resistance stage - ✔✔trying to return to homeostasis
Exhaustion stage - ✔✔cannot return to homeostasis, energy sources depleted,
disease process sets in and permanent symptoms show up.
Function of Mitochondria - ✔✔o Cellular respiration, makes ATP.
