Question 1

The DNP clinician is interested in exploring the issue of patient adherence to NPO guidelines during the 8-hour period prior to surgery. In particular, the DNP clinician suspects educating patients preoperatively about the life-threatening consequences of pulmonary aspiration may increase adherence to NPO guidelines. Formulate an acceptable evidence-based research question for this project that incorporates the five primary PICOT components.

Accepted Answer

Does education about consequences of pulmonary aspiration increase patient adherence to NPO guidelines during the 8-hour preoperative period? 
P = Patient is undergoing a surgical procedure; I = Patient is educated about consequences of pulmonary aspiration; C = Patient adherence to NPO guidelines without education about consequences of pulmonary aspiration is compared to patient adherence to NPO guidelines when relevant education is provided; O = The patient demonstrates adherence to NPO guidelines; T = The time frame is the 8-hour preoperative period.

Question 2

Relate the importance of selecting the research problem to the overall success of the research process.

Accepted Answer

Of all steps in the research process, selection of the research problem is most likely to impact the overall success of the research process. Unless the problem is viable and testable, the research process may be implemented in vain.

Question 3

When developing a research problem, which consideration is most important to the DNP clinician?

Accepted Answer

A)   Relating to some area of practice
B)   Contributing to theory development
C)   Integrating results from an auditing process
D)   Incorporating quantitative research methods A
