KNOWLEDGE Check #2

Question 1You are examining results that are comparing three different educational degrees in nursing (diploma, ADN, and BSN) to their reported levels of commitment to the profession.  The researcher set the alpha level (the level of statistical significance) prior to the study at p< 0.05.

Which of the findings below demonstrate statistical significance, based on the researcher's alpha level?

No decision can be made as to whether a significant difference was found among diploma, associate degree, and baccalaureate graduates' scores.

A significant difference was found among diploma, associate degree, and baccalaureate graduates' scores (r =.40,  p = .001).

A significant difference was found among diploma, associate degree, and baccalaureate graduates' scores (r =.112,  p = .24).

Question 2Which of the following measures of central tendency would be appropriate to describe the average pulse rates of a group of hospitalized patients?

Median

Range

Variance

Mean

Question 3The level of significance usually set in nursing studies is at either:

.03 or .003

.05 or .01

0.5 or 0.1

.005 or .001

Question 4Which of the following types of studies would require the largest sample size?

Phenomenological

Correlational

Grounded theory

Ethnography

Question 5A researcher notes that although no statistical significance was found, some elderly nursing home residents with dementia who were exposed to soothing music for 6 hours daily exhibited lower heart rates and less agitation. This finding would have which type of significance?

Statistical significance

Clinical importance

General inferences

Inferential statistics

Question 6A nursing student is critiquing a study for her nursing research class.  She feels like the study findings are generalizable to other settings and populations because:

it has a small sample size which was obtained by convenience.

the review of literature was extensive and included a conceptual framework.

the sampling criteria for subjects was very narrow and restrictive, to provide a homogenous sample.

there is consistency of the current study's finding with that found in previous research studies.

Question 7According to Brower &Nemec (2017), which of the following is a reason for the importance of following evidence based practice?

Regulating agencies require the implementation of evidence based practice.

Individual practitioners and institutions can be held liable for failure to adhere to evidence based practice policies.

Medicare and insurance providers require evidence based practice for full reimbursement.

Evidence based practice is required for hospitals to attain magnet status.

Question 8According to Brower &Nemec (2017), which of the following would be considered moderate level evidence?

Cohort studies

Expert opinion

Patient preferences

Randomized controlled trials

Question 9In the Iowa Model of Evidence Based Practice, if a nurse brings forward a new research article with ideas that she/he would like to consider implementing on the unit, this would be considered to be:

a knowledge-focused trigger.

a problem-focused trigger.

an opportunity for comparative evaluation between two units.

an opportunity to monitor and analyze structure, processes, and outcome data.

Question 10In this example of a PICO question: “In elderly hospitalized patients, what is the effect of hourly nursing rounds on reducing falls compared with the standard practice of bedside call lights and low bed positioning?”  Hourly nursing rounds represent what element of the PICO format?

I - intervention

P- population

O - outcome

C - comparison
