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.
