Answer to Question 1

4
Rationale 1: This topic is better suited for qualitative research in which hypotheses are not used.
Rationale 2: Methodological studies are nonexperimental, so a hypothesis is not being tested.
Rationale 3: Descriptive studies are nonexperimental, so a hypothesis is not being tested.
Rationale 4: Hypotheses are appropriate for studies that examine relationships between variables, in this case, being catheterized and not being catheterized.

Answer to Question 2

2
Rationale 1: The research question is a statement of what the study concerns.
Rationale 2: A hypothesis is the expected relationship between two or more variables in a population.
Rationale 3: The researcher may have the objective or goal of studying a particular question and should remain objective during the study, but the term objective does not describe the relationship between variables.
Rationale 4: The variables in a study are generally either dependent (affected by the independent variable) or independent (affecting the independent variable). The statement being written regards the relationship between these variables.
