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.
