Answer to Question 1

2
Rationale 1: This statement is incorrect because it identifies a specific population, but it does not contain variables and is not empirically testable.
Rationale 2: Will a cardiac client's (population) heart rate (dependent variable) decrease when listening to calming music (independent variable)? is correct because it contains all the components of a problem statement and is empirically testable.
Rationale 3: Should hospitalized clients (population) be allowed to take medications brought from home (independent variable)? is incorrect because it is a value question as stated. The word should is a clue that is not an appropriate question as stated.
Rationale 4: What were the experiences of psychiatric nurses (population) before and after introduction of antipsychotic medications (independent variables)? is incorrect because it is not empirically testable.

Answer to Question 2

4
Rationale 1: This is not an appropriate topic for a research study because a simple description of rate in this case would likely not be generalizable enough to warrant the study. Further, how would nursing practice or knowledge benefit from the finding?
Rationale 2: This topic is not appropriate for a research study because it would have little impact on the practice of nursing.
Rationale 3: This is not an appropriate topic for research because it is unethical to purposely withhold any form of caring behavior in any setting.
Rationale 4: This topic is ethical, feasible, and significant to nursing practice.
