TWU Pathophysiology Exam 1 Grisby
Pathology the study and diagnosis of disease through examination of organs, tissues, cells, and
bodily fluids. A medical doctor is an example of a pathologist because they identify disease
"Purely laboratory, there are not other parts, use tissue, study tissue and assist in diagnosis"
Physiology functions of body; acid/base; blood/gas "Function of the body, you can look at
blood gases, acid base, heart rate, BP."
Pathophysiology disordered physiological processes associated with disease or injury
"Cancer, pneumonia - disease, altered physiology. Look at blood gas and find it was affected,
asthma, COPD"
Organic disease [s] associated with demonstrable changes in an organ or tissue (destruction
of beta cells)
Functional Disease [s] No morphological abnormalities yet body functions are profoundly
disturbed
Symptomatic disease [s] with symptoms and/or signs
Asymptomatic disease [s] no signs or symptoms
How is the concept of homeostasis used in health and disease? Give some examples. We can
look at lab tests for anything. This person is in homeostasis because this is normal.
Homeostasis has control, a major control is feedback mechanism.
,In disease, you would see abnormal results. Whatever I thought I was trying to measure would
be out of normal range. Feedback was there but not functioning - Grave's disease
Etiology cause of disease
Etiologic agent agent responsible for disease
Pathogenesis origin of disease
Pathogen is a type of etiologic agent
Acute less than 2wks (ex. Acute gastritis, flu)
Chronic 3+ months (ex. COPD, hypertension)
Give an example of prevention and intervention Prevention - vaccine Intervention -
treatment, going to dr.
Compare primary, secondary and tertiary prevention. Primary - alter susceptibility
(vaccine) Secondary - early detection, screening/testing Tertiary - rehab, support, reduce
disability
Symptoms subjective elicited from the patient
Sign objective evidence of disease or condition that can be observed and measured
, Syndrome signs and symptoms whose cause has not been determined
Differential Diagnosis -History -Exam -Hypotheses-try to figure out what was wrong [come
up with a few things based on sign, symptoms, history] -Trying to rule out each of the
alternatives, one that can't is the differential diagnosis. -Use lab results to rule things out -
Diagnosis
Diagnosis [s] determination of the disease or condition present in the patient
Idiopathic etiology don't know cause
Iatrogenic etiology caused by treatment
Treatment [s] management and care plan to control or eliminate disease
Palliative relief symptom relief, make pt comfortable
Prognosis best guess to what outcome will be
Risk factor [s] something that can increase the probability of developing a particular
disease e.g. cardiovascular disease
Latent period prior to any signs or symptoms
