Chapter 01: Introduction
MULTIPLE CHOICE
1. Which of the following is an example of tertiary prevention?
a. Vaccination for rotavirus for children younger than the age of 1 year
b. Surgical amputation of an extremity with osteosarcoma (bone cancer)
c. Screening for gestational diabetes after 24 weeks of pregnancy
d. Sexual education program in elementary schools
e. Increasing taxes for buying
cigarettes
ANSWER: B
Surgical amputation of an extremity with osteosarcoma (bone cancer) is an example in
which when a disease is present the treatment (amputation) is done to reduce the
impact of disease by preventing the tumor from dissemination. Vaccination for rotavirus
for children younger than the age of 1 year, sexual education program in elementary
schools, and increasing taxes for buying cigarettes represent examples of primary
prevention. Screening for gestational diabetes after 24 weeks of pregnancy is an
example of secondary prevention.
2. This historic character observed that childbed fever mortality more common among
women treated by physicians and medical students compared with women treated by
midwives. Based on his observations, he implemented a hand wash policy that resulted in
adecrease in mortality. Name the character that we are talking about.
a. John Snow
b. Edward Jenner
c. D.A. Henderson
d. Leon Gordis
e. Ignaz
Semmelweis
ANSWER: E
Ignaz Semmelweis identified that medical students and physicians transmitted the
disease by not washing their hands after examining bodies at autopsies and conducting
multiple examinations in the clinic.
3. Thanks to the contributions of Edward Jenner, the following disease was eradicated
later by efforts organized by D.A. Henderson:
a. Cholera
b. Smallpox
c. Chickenpox
d. Polio
e. Zika

ANSWER: B
Smallpox was eradicated in 1980. Edward Jenner vaccinated James Phipps in 1796
against smallpox. Almost 200 years later, the World Health Organization (WHO)
commissioned
D.A. Henderson to lead the efforts to eradicate the disease.
4. Over the past century, a marked decline in the mortality rates of many infectious
diseases has been observed. Which of the following is the most likely reason for the
observed decline in mortality rates from common infectious diseases?
a. Development of penicillin
b. Development of insulin
c. Development of vaccines
d. Improvement in social conditions
e. Worse sanitation and unsafe
water ANSWER: D
Although medical treatments potentially helped in the decrease of infectious
diseases, the advancement in social conditions played a major role. These
improvements include better sanitation, safe disposal of waste, better nutrition, and
improvement in housing conditions.
