Question 2
Numerous studies show that patients want to have conversations about their end-of-life care; however, many physicians do not feel comfortable with the topic and are now asking hospice nurses to have these conversations. Which type of research method should be used to determine the impact of this change?
Correct Answer: D
Rationale: To measure the actual impact on patients, a quantitative patient survey is the most appropriate and direct method. Focus groups give opinions; only patients can report their own experience of the change.
