Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity.

Rationale: The absence of the pedal pulse may not be significant if the patient has poor peripheral circulation or if the healthcare provider is focused on other pulse points.

Rationale: All the listed interventions are essential for promoting patient safety. Assessing the patient's ability to ambulate and transfer helps prevent falls, demonstrating the signal system ensures effective communication in emergencies, and checking the patient's identification band aids in accurate identification and treatment. By combining these interventions, healthcare providers can enhance patient safety and quality of care.

Rationale: When removing a contaminated gown, the nurse should ensure the first thing touched is the waist tie and neck tie at the back of the gown. This procedure helps prevent contamination by ensuring that the outer surface of the gown, which is likely to be contaminated, is not touched during removal. By touching the back ties first, the nurse minimizes the risk of transferring any contaminants to themselves or the environment.
