MULTIPLE CHOICE
1. C.Q. was recently exposed to group A hemolytic Streptococcus and subsequently
developed a pharyngeal infection. His clinic examination reveals an oral temperature
of 102.3F, skin rash, dysphagia, 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
Etiology refers to the proposed cause or causes of a particular disease process. A
sore throat is the manifestation of the disease process. Genetic susceptibility refers
to inherited tendency to develop a disease. Pharyngitis refers to inflammation of the
throat and is also a clinical manifestation of the disease process.
2. 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
Primary prevention is prevention of disease by altering susceptibility or reducing
exposure for susceptible individuals by providing vaccination. Secondary prevention
is the early detection, screening, and management of the disease. Tertiary prevention
includes rehabilitative and supportive care and attempts to alleviate disability and
restore effective functioning. Disease treatment involves management of the disease
once it has developed.
3. 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
Secondary prevention is the early detection, screening, and management of the
disease such as prescribing diet and exercise for an individual who has already
developed obesity.
Primary prevention is prevention of disease by altering susceptibility or reducing
exposure for susceptible individuals. Tertiary prevention includes rehabilitative and
supportive care and attempts to alleviate disability and restore effective functioning.
Disease treatment involves management of the disease once it has developed.
4. A patient with high blood pressure who is otherwise healthy is counseled to restrict
sodium intake. This is an example of
a. primary prevention.
b. secondary prevention.
c. tertiary prevention.
d. disease treatment.
ANS: B
Secondary prevention is the early detection, screening, and management of the
disease, such as by prescribing sodium restriction for high blood pressure. Primary
prevention is prevention of disease by altering susceptibility or reducing exposure
for susceptible individuals. Tertiary prevention includes rehabilitative and supportive
care and attempts to alleviate disability and restore effective functioning. Disease
treatment involves management of the disease once it has developed.
5. After suffering a heart attack, a middle-aged man is counseled to take a cholesterol-
lowering medication. This is an example of
a. primary prevention.
b. secondary prevention.
c. tertiary prevention.
d. disease treatment.
ANS: C
Tertiary prevention includes rehabilitative and supportive care and attempts to
alleviate disability and restore effective functioning such as prescribing a cholesterol-
lowering medication f olloNwiRng Ia h eGa r t Ba t.t aCc k Primary prevention is prevention of
disease by altering susceptibility or reducing exposure for susceptible individuals.
Secondary prevention is the early detection, screening, and management of the disease.
Disease treatment involves management of the disease once it has developed.
6. A patient has been exposed to meningococcal meningitis, but is not yet
demonstrating signs of this disease. This stage of illness is called the stage.
a. prodromal
b. latent
c. sequela
, d. convalescence
ANS: B
Incubation refers to the interval between exposure of a tissue to an injurious agent
and the first appearance of signs and symptoms. In infectious diseases, this period is
often called the incubation (latent) period. Prodromal refers to the appearance of the
first signs and symptoms indicating the onset of a disease. These are often
nonspecific, such as headache, malaise, anorexia, and nausea, which are associated
with a number of different diseases.
Sequela refers to subsequent pathologic condition resulting from a disease.
Convalescence is the stage of recovery after a disease, injury, or surgical operation.
7. A disease that is native to a particular region is called
a. epidemic.
b. endemic.
c. pandemic.
d. ethnographic.
ANS: B
A disease that is native to a particular region is called endemic. An epidemic is a
disease that spreads to many individuals at the same time. Pandemics are epidemics
that affect large geographic regions, perhaps spreading worldwide.
8. In general, with aging, organ size and function
a. increase.
b. decrease.
c. remain the same.
d. are unknown.
ANS: B
In general, with aging, organ size and function decrease.
9. The stage during which the patient functions normally, although the disease
processes are well established, is referred to as
a. latent.
b. subclinical.
c. prodromal.
d. convalescence.
ANS: B
The stage during which the patient functions normally, although the disease
processes are well established, is called the subclinical stage. The interval between
exposure of a tissue to an injurious agent and the first appearance of signs and
symptoms may be called a latent period or, in the case of infectious diseases, an
incubation period. The prodromal period, or prodrome, refers to the appearance of
, the first signs and symptoms indicating the onset of a disease. Convalescence is the
stage of recovery after a disease, injury, or surgical operation.
MULTIPLE RESPONSE
1. Your patient’s red blood cell is slightly elevated today. This might be explained by
(Select all that apply.)
a. gender difference.
b. situational factors.
c. normal variation.
d. cultural variation.
e. illness.
ANS: A, B, C, E
Gender, situations (e.g., altitude), normal variations, and illness may all determine
red blood cell count. Culture affects how manifestations are perceived (normal
versus abnormal).
2. Socioeconomic factors influence disease development because of (Select all that
apply.)
a. genetics.
b. environmental toxins.
c. overcrowding.
d. nutrition.
e. hygiene.
ANS: B, C, D, E
Socioeconomic factors influence disease development via exposure to environmental
toxins (occupational) and overcrowding, nutrition (over- or undernutrition), and
hygiene (e.g., in developing countries). Genetics is not influenced by socioeconomic
factors.
TRUE/FALSE
1. When the cause is unknown, a condition is said to be
idiopathic ANS: T
Many diseases are idiopathic in nature.
2. The nurse is swabbing a patient’s throat to test for streptococcal pharyngitis. The
nurse must understand that tests such as this differ in the probability that they will be
positive for a condition when applied to a person with the condition; this probability
is termed sensitivity.
ANS: T
The sensitivity of any test refers to the probability that the test will be positive when
