*Intro to Patho*
What is pathophysiology? correct answer: study of abnormalities in physiologic functioning of living beings & the physiologic
... [Show More] responses of an organism to disruptions in it's internal & external environ
How is pathophysiology different from pathology & physiology? correct answer: - pathology = study of causes/effects of diseases
- physiology = study of normal functions of living organisms & their parts
What are the 4 components of pathophysiology? correct answer: 1. Etiology
2. Pathogenesis
3. Clinical Manifestations
4. Treatment
1. Etiology correct answer: study of causes/reasons for phenomenon, disease, & injury
*often difficult to pinpoint bc of role of genetics & environ
What is meant by idiopathic? Ex? correct answer: = disease/condition is of unknown cause
> ex: chronic fatigue
What is meant by iatrogenic? Ex? correct answer: = disease/condition caused by unwanted or unintended medical intervention > ex: hair loss caused by chemo therapy
What is meant by risk factor? correct answer: = factor that when present incr the risk for disease
2. Pathogenesis correct answer: = development of disease from initial stimulus to expression of manifestations of the disease > ex: direct effects of initiating event, physiological responses, & compensatory mechanisms
3. Clinical manifestations
Signs, Symptoms, & Syndromes? correct answer: = signs & symptoms (S/Sx)
- S = objective, observable manifestations of the disease
- Symptoms = subjective feelings of abnormality
- Syndrome = disorder that the etiology of S/Sx has not been determined for yet
What are the specific stages of clinical manifestations? correct answer: > latent period = from exposure to injurious agent to 1st appearance of S/Sx (aka incubation period for infectious disease)
> prodromal period (prodrome) = appearance of S/Sx & onset of disease
> manifest illness (acute phase) = disease at full intensity w most severe S/Sx
- silent period(s) = when S/Sx ease/disappear before returning
- subclinical stage = when pt functions normally even though disease processes are established
> convalescence = recovery after disease, injury, or operation
Define sequela & complication correct answer: - s [Show Less]
