The impact of ethics and work-related factors on nurse practitioners' and physician assistant's views on quality of primary healthcare in the United States. Applied Nursing Research, 27(3), 152-156. Introduction: Ulrich and colleagues (2014) noted that many primary care services are provided by nurse practitioners (NPs) and physician assistants (PAs), and it is important for them to have ethical knowledge in managing challenging practice issues. However, little is known about the relationships between ethics and other work-related factors with the delivery of quality care. Thus, the purpose of this study was "to describe how NP and PA perceptions of their ethics preparedness, confidence, physician collegiality, and autonomy, along with the patient demands they encountered, influence perceived quality of care in their clinical practice" (Ulrich et al., 2014, p. 153). The findings from this correlational study were as follows: "Ethics preparedness and confidence were significantly associated with perceived quality of care (p

Explanation / Answer

Answer a

The value for Pearson r for the relationship between "Perceived quality of care" and "Patient care demand" is -0.42. The relationship is negative since the value of Pearson r negative. The relationship is as per our expectation because if there are unnecessary demands from patient which practitioner could not fulfil, then, his/her relationship practitioner would suffer. This in turn will have negative impact on the perceived quality of care.

Since the magnitude of correlation is 0.42, we can say strength of relationship is moderate. The relationship is statistically significant as p<0.01.

Answer b

The value 1.00 along the diagonal of Table 2 indicates correlation of variable to itself which is a perfect positive linear relationship.
