TRUE/FALSE
1.Normal ranges for physiologic parameters are arbitrarily defined based on population
sampling.
ANS: T
- Values outside the normal range for a particular variable are always indicative of disease.
ANS: F - Illness and disease always coexist.
ANS: F - Normalcy is culturally defined.
ANS: T - A change in a physiologic variable is more significant than the absolute values.
ANS: T - Most homeostatic mechanisms function via positive feedback loops.
ANS: F - Homeostatic control mechanisms function primarily during disease states.
ANS: F - Epidemiology is the study of disease expression in individuals.
ANS: F - The etiology and pathogenesis of most disease states have been well defined by research.
ANS: F
1 / 4 - Individuals experiencing the same disease process exhibit the same clinical
manifestations.

ANS: F
MULTIPLE CHOICE - C.Q. was recently exposed to group A hemolytic Streptococcus and subsequently
developed a pharyngeal infection. His clinic examination reveals an oral temperature of
102.3° F, skin rash, and reddened throat mucosa with multiple pustules. He complains of
sore throat, malaise, and joint stiffness. A throat culture is positive for Streptococcus, and
antibiotics have been prescribed. The etiology of C.Q.’s disease is
a
.
a sore throat.
b
.
streptococcal infection.
c
.
genetic susceptibility.
d
.
pharyngitis.
ANS: B - Which of the following is a statement about disease pathogenesis?
a
.
Pharyngitis is caused by group A hemolytic Streptococcus infection.
b
.
Streptococcal infection activates immune cells, leading to inflammation.
c
.
Sore throat and mucosal inflammation are common signs and symptoms of
pharyngeal infection.
d
.
Antibiotics are the treatment of choice for streptococcal infection.
ANS: B - Which of the following assessment findings indicates an alteration in homeostatic control
mechanisms?
a
.
Fever
b
.
Throat pain
c
.
Joint stiffness
d Positive throat culture
3 / 4
.
ANS: A - Most homeostatic mechanisms function on a negative-feedback principle, which
facilitates
a
.
minimal response to environmental changes.
b
.
an amplified response.
c
.
a rapid response rate.
d
.
steady-state stability.
ANS: D - A 17-year-old college-bound student receives a vaccine against an organism that causes
meningitis. This is an example of
a
.
primary prevention.
b
.
secondary prevention.
c
.
tertiary prevention.
d
.
disease treatment.
ANS: A - An obese but otherwise healthy teen is given a prescription for a low-calorie diet and
exercise program. This is an example of
a
.
primary prevention.
b
.
secondary prevention.
c
.
tertiary prevention.
d
.
disease treatment.
ANS: B
