12-14 Quiz

Question 1

Which statement best describes a population?

Trauma clients
hospitalized in an intensive care unit during January 2010

This statement describes a population because it describes a
complete set of persons that possess a common characteristic (i.e., clients who
have experienced trauma requiring hospitalization in an intensive care unit).

Four hundred nurses
selected from a membership list of American Nurses’ Association (ANA) members

Members of a cult
identified by other members of the same cult

Members of families
of clients undergoing surgery, sitting in the waiting room of St. Francis
Hospital

Question 2

Which sampling method would be most practical and provide
the most reliable data to study the ethical conflicts experienced by registered
nurses who work in city, county, and federal prisons?

Simple random
sampling

Cluster random
sampling

Cluster random sampling would be the most practical and
yield the most reliable data because systematic selection of location for
participants will improve reliability of data, and because the volume and
locations of city, county, and federal prisons presents an impractical,
expensive, and time-consuming approach.

Quota sampling

Purposive sampling

Question 3

The study design proposes advertising in the local newspaper
to attract subjects for a study. The subjects would be paid $75 for their
participation in the study. How should the nurse interpret this plan?

It is not ethical to
reimburse study subjects for participation.

The reimbursement
offered is not enough to attract subjects.

The results of this
study may not be generalizable.

When subjects are drawn into a study for a specific reason,
the results are not generalizable to other groups.

Most studies do not
have sufficient funding to use this design.

Question 4

A researcher asks another nurse to use a study instrument to
score a questionnaire completed by study participants. The researcher has
previously used the instrument to score the questionnaire and will compare the
two results. Which type of reliability is this researcher trying to establish?

Homogeneity

Internal consistency

Equivalence

Stability

Stability measures the consistency of a measurement over
time.

Question 5

According to the research report, the nurse researcher
tested a study instrument’s validity using the technique of factor analysis.
What other test could the researcher have used to test the same type of
validity?

Scale homogeneity

Known-groups
procedure

Factor analysis and know-groups procedure both test
construct validity.

Interrater

Test-retest

Question 6

A study was conducted to evaluate shivering in the
post-operative patient. The study measures subjects’ weight in pounds and
temperature in centigrade degrees. What should the reader consider about the
level of measurement of these two parameters?

Additional
information is needed before any determination of level of measurement can be
made.

Temperature is
measured at ratio level.

Weight is usually
consider to be measured at the ratio level.

Weight is generally considered to be measured at ratio
level, which is the highest level of measurement. Ratio level of measurement
includes data that can be categorized and ranked; in addition, the distance
between ranks can be specified, and a “true” or natural zero point
can be identified.

Both of these
measurements are at interval level.

Question 7

A question asks subjects to respond to the following
statement: “The nursing care I received during my hospital stay considered
my needs as an individual.” They were asked to identify, on a five-point
scale, the degree to which they agreed or disagreed with the statement. This is
an example of which scale?

Semantic
differential scale

Sort scale

Likert scale

A Likert scale is a five-point to seven-point scale on which
respondents are asked to indicate the extent/degree to which they agree or
disagree with a neutrally worded statement.

Visual analog scale

Question 8

The nurse educator is reading a published study conducted to
collect data on the process by which student nurses are evaluated during a
clinical rotation. Which data collection method would this educator recognize
as appropriate for this study?

Q sort

Questionnaire

A questionnaire would be the best way to collect the data
because the data are sensitive in nature and a questionnaire would allow the
data to be collected in a way that the subjects are anonymous.

Observation

Interview

Question 9

Which question is correctly stated for use in a research
study questionnaire?

Do you believe that being
fat is an illness?

Do you generally eat
breakfast?

What are you least
likely to purchase, medicine or food?

Where do you plan to
work after graduation?

This question is straightforward, easily understandable, and
is open-ended.

Question 10

A nurse researcher is trying to decide on the best method of
data collection in a study. What is the advantage of an interview over a
questionnaire as a method of data collection in a study?

They are less
time-consuming

In-depth responses
can be obtained

There is less bias

Response rate is low
