Answer to Question 1

D
Feedback:
A fundamental distinction that is especially relevant in quantitative research is between studies whose primary intent is to describe phenomena and those that are cause-probing. Specific purposes on the description/explanation continuum include identification, description, exploration, prediction/control and explanation. Many nursing studies can also be classified in terms of a key EBP aim: therapy/treatment/intervention; diagnosis and assessment; prognosis; etiology and harm; and meaning and process.

Answer to Question 2

1
Rationale 1: Samples of 5,000 or 6,000 are often sufficient to estimate the characteristics of the entire population of the United States.
Rationale 2: The researcher should set a sample size minimum, but this one is probably too low to generalize to the entire United States.
Rationale 3: This would not be an effective way to ensure generalizability.
Rationale 4: The more homogeneous a sample is, the less generalizable the results are to a larger population.
