Which of the following may explain the reason for the observed
association? - ✔✔✔ Correct Answer > Confounding by exercise level for those
with daily exposure to automobile traffic
The Institute for Healthcare Improvement uses a rapid cycle
improvement model. The key features of this model are: - ✔✔✔ Correct
Answer > Plan, Do, Study, Act
Which of the following is an example of a period prevalence rate? - ✔✔✔
Correct Answer > Percentage of people in the US who had asthma during the
past 12 months of any particular year
,Which of the following statements best describe efficacy? - ✔✔✔ Correct
Answer > It is an estimate of the benefit of treatment under ideal
conditions
It is an estimate of the reduction of disease in treated groups
Which of the following is an advantage of the case-control study
design? - ✔✔✔ Correct Answer > It is possible to study more than one
exposure
A large case-control study using multiple recruitment centers was
conducted comparing 2,987 lung smoker cases to 3,013 other
hospitalized persons selected as controls. One objective was to study
the association between occupational exposure to chemicals and lung
cancer. After compiling the data, the investigators noted that 90% of
persons with lung cancer were smokers while 67% of the controls were
smokers. The most practical and efficient way to eliminate differences
between the cases and controls with regard to smoking would be to: -
✔✔✔ Correct Answer > Classify subjects according to smoking status and
compare occupational chemical exposures by each stratum of smoking
,What is being compared in a cohort study design? - ✔✔✔ Correct Answer >
The incidence of a disease between exposed and non-exposed
individuals
Analytic epidemiology is best described as: - ✔✔✔ Correct Answer > Studies
that investigate origins and casuals' factors of health-related events
You are part of a research group investigating association between
exposure and disease. Which study design is a best fit for this type of
study: - ✔✔✔ Correct Answer > Case-Control Study
The provider is concerned about what appears to be an increase in the
mortality rate for their community. Mortality is an example of which of
the following: - ✔✔✔ Correct Answer > Vital statistic
An example of a tertiary prevention measure for chronic obstructive
pulmonary disease is: - ✔✔✔ Correct Answer > Pulmonary Rehabilitation
, A study is conducted for a pharmaceutical agent that has shown
promise for reducing heart disease among women. In order to more
fully test the agent, an additional study is done restricting the
participants to be randomized to those who have a history of
hypertension. Which of the following advantages cannot be claimed by
the researchers? - ✔✔✔ Correct Answer > The generalizability of the study is
increased
What is the main advantage of the randomization of the 168 study
participants to one of the two drug treatment groups? - ✔✔✔ Correct Answer
> Reduces selection bias
After entry into the study, patients were first classified into three
groups, those who had a previous AMI, those with a first AMI who were
at high risk for other cardiovascular diseases such as congestive heart
failure, and those with a first AMI who were at low risk for other
cardiovascular diseases. Which term best describes the study design? -
✔✔✔ Correct Answer > Randomized clinical trial with stratified randomization
