portage pathophysiology exam 1
True/False:
Persistent metaplasia can lead to dysplasia. - ANStrue
True/False:
Barrett esophagus is an example of dysplasia. - ANSfalse (Barrett's esophagus is
METAplasia)
True/False:
Persistent dysplasia eventually results in cancer. - ANStrue
True/False:
Hypertrophy can occur under normal and pathological conditions. - ANStrue
Match definitions for: sensitivity, reliability, validity, specificity - ANSSensitivity: proportion of
people WITH a disease that test positive for the disease
Reliability: likelihood of getting same result with repeat testing
Validity: HOW a tool measures what it is intended to measure
Specificity: people WITHOUT a disease who test negative for the disease
Which are true of the mitochondria? Select all that apply. - ANSIt is involved in cellular
respiration
They play a role in apoptosis
Which of the following are true of the cell? Select all that apply. - ANSProteins carry out the
functions of the cell membrane
Lysosomes are the digestive system of the cell
Microfilaments are thin, threadlike cytoplasmic structures
Which are true of the cell membrane? Select all that apply. - ANSControls the transport of
materials from the outside fluids to within
Helps with the conduction of electrical currents in nerve and muscle cells
Aids in the regulation of cell growth and proliferation
Which are false of the mitochondria? Select all that apply. - ANSThey are found far from the
site of energy consumption
They control free radicals
High blood pressure is an example of which of the following? - ANSPathophysiology
(Pathophysiology is the study of disease, high blood pressure is an example of a disease)
A patient complains of chest pain and an elevated blood pressure. What are these examples
of? - ANSsigns (high blood pressure) AND symptoms (pt complaint of chest pain)
