ANSWERS ALREADY GRADED A+
The nurse practitioner is reviewing a recent study that utilizes analytic epidemiology by means of a
cohort study design. The cohort study design informs the practitioner about which of the following -
ANS-Outcomes that develop from an exposure
A group of providers have implemented population-based intervention and are now assessing the
efficacy of the intervention. Which of the following would be an example of a population based
outcome? - ANS-Decreased mortality rate compared to previous year
Appraisal of research publications is critical as providers assess for relevance to population health.
Which of the following items should be considered during the appraisal process? Select all that apply. -
ANS-Outcome measure, Transparency, Internal Validity
Which of the following statements best describes the reason for conducting the study as a double-blind
trial? - ANS-Double blinding ensures that potential biases regarding selection, follow-up, and analysis
can be reduced
The following data come from a study of approaches to smoking cessation. Smokers who want to quit
were randomized to one of four groups: control ..... brochures and a monthly phone call from a
counselor. Participants received mailed surveys at 8, 16, and 24 months after randomization. The results
, after 2 years are in the table below. Which group had the least success in terms of quitting smoking? -
ANS-Group QS
What is being compared in a cohort study design? - ANS-The incidence of a disease between exposed
and non-exposed individuals
Analytic epidemiology is best described as: - ANS-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: - ANS-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: - ANS-Vital statistic
An example of a tertiary prevention measure for chronic obstructive pulmonary disease is: - ANS-
Pulmonary Rehabilitation
Which of the following statements best describe efficacy? - ANS-It is an estimate of the benefit of
treatment under ideal conditions
It is an estimate of the reduction of disease in treated groups
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? - ANS-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? - ANS-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? - ANS-Randomized clinical trial with stratified randomization
