World Health Organization definition of health ANS a state of complete physical, mental, and
social well-being and not merely the absence of disease or infirmity
Healthy People 2020 Health Definition ANS Health is an interaction between an individual's
biology and behavior, physical and social environments, government policies and interventions, and
access to quality health care.
Attain high-quality, longer lives free of preventable disease, disability, injury, and premature death.
Achieve health equity, eliminate disparities, and improve the health of all groups.
Create social and physical environments that promote good health for all.
Promote quality of life, healthy development, and healthy behaviors across all life stages.
Physiology ANS The study of body function
Pathophysiology ANS is the study of the body's response to dysfunction or disease
disease ANS An abnormal state in which the body is not functioning normally. Interruption,
cessation, or disorder of a body system or organ structure.
Etiology
Pathogenesis
Morphological changes
Clinical Manifestations
Diagnosis
Clinical Course ANS Aspects of the disease process? (6)
Biological agents: bacteria, viruses
Physical: traumas, radiation, burns
,Chemical agents: poisons, alcohol
Genetic inheritance
Nutritional excesses or deficits: obesity ANS Etiology Factors of Disease? (5)
Diagnostic Reasoning ANS Hallmark of clinical judgment and requires careful analysis. Method
of collecting and analyzing clinical information with the following components: (1) attending to
initially available cues, (2) formulating diagnostic hypotheses, (3) gathering data relative to the
tentative hypotheses, (4) evaluating each hypothesis with the new data collected, and (5) arriving at a
final diagnosis.
Symptom Analysis ANS Assessment and clinical decision making. The fixed properties of a
diagnostic test relate to its sensitivity and specificity.
Epidemiology ANS The study of disease occurrence in a population
Diagnosis ANS designation as to the nature or cause of a health problem
History
Physical Exam
Diagnostic Tests ANS The diagnostic process requires? (3)
History (Hx) ANS used to obtain a person's account of their symptoms and their progression and
the factors that contribute to a diagnosis
Physical Exam (PE) ANS Done to observe for signs of altered body structure or function
Diagnostic Tests ANS Ordered to validate what is thought to be the problem; also ordered to
determine other possible health problems that were not obtained from the Hx and PE but may be
present given the signs and symptoms.
, Normal ANS Established statistically from test results obtained from a selected sample of people.
This value represents the test results that fall within the bell curve or the 95% distribution.
Validity ANS The extent to which a measurement tool measures what it is extended to measure.
Reliability ANS Ability of a test to yield very similar scores for the same individual over
repeated testings. Consistency.
Sensitivity ANS The proportion of people with a disease who are positive for that disease on a
given test or observation; true-positive result.
Specificity ANS The proportion of people without the disease who are negative on a given test or
observation; true-negative result
Greater ANS the higher specificity, the ________ the % of individuals who will have negative
for normal results, if they do not have the disease or condition
Predictive Value ANS Extent to which a test can differentiate between presence or absence of a
person's condition. Depend more heavily on the prevalence of the condition in the population.
Positive Predictive Value
Prevalence ANS The probability that a person with a positive test result is truly positive refers to
________________. Thia value rises with ______________?
Negative Predictive Value
Falls ANS The probability that a person with a negative test result is truly disease free. This value
_________ with prevalence.
Incidence
# of new cases/ population at risk = Incidence ANS The number or rate of new cases of a
particular condition during a specific time.
