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 102.3° F, 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 ofthe throat and
is also a clinical manifestation of the disease process.

1
, 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 individualsby providing
vaccination. Secondary prevention is the early detection, screening, and management of the disease. Tertiary preventionincludes
rehabilitative and supportive care and attempts to alleviate disability and restore effective functioning. Disease treatment involves
management of the disease once it has developed.
REF: Pg. 9
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 orreducing
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.
REF: Pgs. 9-10
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.
REF: Pgs. 9-10
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 following a heart attack. 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.
REF: Pg. 3
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.
REF: Pg. 6
8. In general, with aging, organ size and function
a. increase.
b. decrease.
c. remain the same.
d. is unknown.
ANS: B
In general, with aging, organ size and function decrease.
REF: Pg. 5
9. The stage during which the patient functions normally, although the disease processes are well established, is referredto 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 periodor, inthe caseof infectious diseases, anincubationperiod. 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.

10. 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).
REF: Pgs. 5-6
11. Socioeconomic factors influence disease development due to (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.

13. 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
.
ANS:
sensitivity
The sensitivity of any test refers to the probability that the test will be positive when applied to a person with the condition and will
not provide a false negative result. In contrast, specificity is the probability that a test will be negative when applied to a person who
does not have a given condition.
