PATHOPHYSIOLOGY BSN 346
(CHAPTER 1-23) 2026 REAL
QUESTIONS WITH EXPERTLY
VERIFIED ANSWERS.
What is anaplasia? - correct answer -Loss of cell differentiation
and tissue organization
*Chapter 1*
What is the definition of pathophysiology? - correct answer -
(ology) the study of
(pathophysi) abnormalities in physiologic functioning due to
disease or injury
What is etiology? - correct answer -The study of the causal
factors that provoke a particular disease or injury
, Page | 2
Define pathogenesis? - correct answer -A description of how
etiologic factors are thought to alter physiologic function and lead
to the development of clinical manifestations that are observed in
a particular disorder or disease
What are the objective and subjective clinical manifestations of a
disease? - correct answer -Objective manifestations: signs found
through physical exam or diagnostic tests
Subjective manifestations: symptoms described by the patient
What are the 4 stages of an illness and what do they signify? -
correct answer -1) Latent- the period of incubation before a
disease manifests
2) Prodromal- the first signs of disease appear, often non-specific
such as body aches/fever
3) Acute- period with greatest severity of s/s
4) Convalescence- recovery
What is a sequela? - correct answer -a condition which is the
consequence of a previous disease or injury
, Page | 3
What is validity? - correct answer -the degree to which a test
measures what it says it measures. the peabody test said it
measured intelligence. however, it only tests receptive
vocabulary, so that's not valid.
What is accuracy? - correct answer -a measure of how close a
measurement comes to the actual or true value of whatever is
measured
What is precision? - correct answer -a measure of how close a
series of measurements are to one another
What is a positive predictive value? - correct answer -probability
that a pt w/ a positive test truly has the disease. The more specific
a test, the higher its PPV
prevalence dependent: the higher the disease prevalence, the
higher the PPV of the test for that disease
What is negative predictive value? - correct answer -probability
that a pt w/ a neg test truly does not have the disease. The more
sensitive a test, the higher its NPV.
, Page | 4
Prevalence dependent: the lower the disease prevalence, the
higher the NPV of the test for that disease
What is sensitivity in a test? - correct answer --its ability to detect
people who do have the disease
= the percentage of the people with a disease that is correctly
detected or classified
What is specificity of a test? - correct answer -- its ability to detect
people who do not have the disease
= the percentage of the disease-free people who are correctly
classified or detected
What are 4 examples of characteristics that effect the normalcy in
tests? - correct answer -Cultural (defines abnormal behavior)
Age Differences (decrease skin turgor)
Gender Differences (men ^RBCs)
Situational Differences (high altitude ^RBCs)
Time variations (time of day)
