WGU D514 EXAM QUESTIONS WITH |\ |\ |\ |\ |\
ANSWERS
The quality improvement team is reviewing quarterly incident
|\ |\ |\ |\ |\ |\ |\ |\
reports and evaluating the effect of Six Sigma strategies on the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
quantity of medication errors over the past two years. The team
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
hypothesizes a continuous reduction in medical errors for each |\ |\ |\ |\ |\ |\ |\ |\ |\
quarter.The sample consists of patient clinical and demographic
|\ |\ |\ |\ |\ |\ |\ |\
characteristics. Unfortunately, causation cannot be determined |\ |\ |\ |\ |\ |\
from the data available.Which research method should be used
|\ |\ |\ |\ |\ |\ |\ |\ |\
to test the team's hypothesis?

A hospital researcher has access to one year of hospital
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
emergency department claims data. The researcher is |\ |\ |\ |\ |\ |\ |\
investigating the association of race on the timeliness of delivery |\ |\ |\ |\ |\ |\ |\ |\ |\
of care. The sample includes information on patient
|\ |\ |\ |\ |\ |\ |\ |\ |\
demographics, insurance information, and emergency |\ |\ |\ |\ |\
department factors. Due to patient confidentiality, the sample |\ |\ |\ |\ |\ |\ |\ |\
does not include patient clinical information and outcomes.Which
|\ |\ |\ |\ |\ |\ |\
research method should be used?

A policy analyst is interested in determining if the prospective
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
payment system (PPS) has improved hospital efficiency over time
|\ |\ |\ |\ |\ |\ |\ |\
during the past ten years. The sample for analysis consists of ten
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
years of data after the introduction of the PPS and includes
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
measures of efficiency and other relevant control variables. The
|\ |\ |\ |\ |\ |\ |\ |\ |\
analyst hypothesizes that hospital efficiency should have
|\ |\ |\ |\ |\ |\ |\
increased each year after the PPS was implemented.Which
|\ |\ |\ |\ |\ |\ |\ |\
research method should the analyst use?

Which type of data analysis could be used in quantitative
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
research?
Reporting the gender of participants |\ |\ |\ |\
Ranking the severity order with 1 as the worst and 4 as the best
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Reporting the distribution of results or outcomes
|\ |\ |\ |\ |\ |\
Using categorical variables with 0=no and 1=yes - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Reporting the distribution of results or outcomes
|\ |\ |\ |\ |\ |\ |\
What is a characteristic of qualitative research methods?
|\ |\ |\ |\ |\ |\ |\
Utilizes large sample sizes
|\ |\ |\
Determines causal relationships |\ |\
, Generalizes results to the population |\ |\ |\ |\
Introduces subjectivity to data collection - CORRECT ANSWERS|\ |\ |\ |\ |\ |\ |\ |\
✔✔Introduces subjectivity to data collection |\ |\ |\ |\
Many physician practices now utilize an electronic health record
|\ |\ |\ |\ |\ |\ |\ |\ |\
(EHR) system that includes a secure messaging feature. Some of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
these practices have extended their contact with patients by
|\ |\ |\ |\ |\ |\ |\ |\ |\
conducting virtual visits between people with diabetes and |\ |\ |\ |\ |\ |\ |\ |\
nurses who are certified diabetes educators. The remote
|\ |\ |\ |\ |\ |\ |\ |\
technology includes the ability to monitor blood glucose data to |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
determine if these values are within goal range. After six months,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the results of the blood glucose levels for the group participating
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
in the virtual visits were evaluated.Which research method was

A researcher wants to determine whether continuity of care is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
improved with the use of coordination of care documents among
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
primary care physicians and specialists. The researcher decides
|\ |\ |\ |\ |\ |\ |\ |\
to review various published studies to assess the clinical
|\ |\ |\ |\ |\ |\ |\ |\ |\
effectiveness of these documents on patient outcomes.Which |\ |\ |\ |\ |\ |\ |\
research method is being used? |\ |\ |\ |\
