CPH Exam Practice Questions
-0.9 - ANS-Which of the following estimates of an odds ratio most strongly suggests a
computational error?
- 7.8
- 1.2
- -0.9
- 20.9
2.5/1000 - ANS-Out of a population of 500,000 people, 500 were observed for two years. Five
developed disease. What is the incidence density rate?
A protein - ANS-U.S. mandates Creutzfeld-Jacob disease, a prion disease to be nationally
notifiable from all the states. What kind of infectious agent is a prion?
Add chlorine to water storage containers - ANS-In low resource countries during an outbreak,
what simple, low-tech sanitation measure can dramatically reduce the spread of enteric bacteria
and viruses?
An analysis to justify and allocate resources - ANS-New to your leadership position, you realize
that two of the programs you manage have similar functions, and work with the same population
in the same area. Data trends over the past 5 years suggest that the health condition has
improved significantly. You decide that only one program is needed to provide the necessary
services to the community. This is an example of:
ANOVA - ANS-National Physical Activity Guidelines for Americans suggest adults need to
participate in at least 150 minutes per week in moderate intensity physical activity for substantial
health benefits. A study was designed to test whether there is the difference in mean time (in
minutes) spent in moderate intensity physical activity in adults with no, mild, moderate and
severe depression. Time spent in moderate intensity physical activity is a continuous measure
which can be assessed using an accelerometer. Which among the following is the most
appropriate statistical technique to test the difference in time spent in moderate intensity
physical activity between adults with no, mild, moderate and severe depression?
- Spearman correlation
- ANOVA
- t-test
- chi-quared test
Assists to identify and prioritize health problems - ANS-A public health professional is asked to
conduct a needs assessment for a community. A needs assessment:
, at all times, whether they are on or off duty. - ANS-Ethical standards apply to government
officers and employees. For such individuals, these standards apply:
Be neutral - ANS-Facilitation takes work and in a meeting of multiple stakeholders it becomes
important for the facilitator to prioritize his or her role. Above all the facilitator should:
Biomonitoring of chemicals or metabolites of the chemicals in blood and urine - ANS-Which of
the following methods is the most accurate exposure assessment in workers?
- Determination of the chemical in the air
- Biomonitoring of chemicals or metabolites of the chemicals in blood and urine
- Determination of the chemical on the skin
- Estimation of the exposure by taking an occupational history
By using a State Implementation Plan (SIP) approved by the EPA - ANS-By what programmatic
mechanism does the U.S. Environmental Protection Agency (EPA) work with states to
implement national environmental standards such as NAAQS?
Case-control - ANS-Which of the following best describes a study where exposure histories is
collected from a group of persons with a specific disease and from a comparison group to
determine the relative frequency of an exposure?
- Clinical Trial
- Randomized control trial
- Case-control
- Cohort
Chlorination - ANS-Which of the following disinfection methods is most commonly used in US
drinking water supply systems?
- Ozonation
- Bromination
- Chlorination
- Ultraviolet irradiation
Consulting stakeholders to decide what best serves public interest - ANS-Which of these has
been defined as a core function of public health?
- Maintaining the census to define populations
- Consulting stakeholders to decide what best serves public interest
- Conducting research to solve all population health problems
- Acting in an ethical manner
Creating maximum benefit for all while minimizing individual harm - ANS-When making
decisions, public health leaders face the ethical challenge of:
cultivate a new group of leaders - ANS-Succession planning involves a defined plan to:
