A nurse is preparing a sterile field for a client who requires a sterile procedure. Which of the following actions should the nurse plan to take?

Choice A reason: Advancing the walker and taking a step towards it is the correct technique, ensuring stability by moving the walker first, then stepping. This maintains balance and prevents falls, aligning with safe walker use protocols, so no intervention is needed for this action.
Choice B reason: Taking multiple steps while holding the walker compromises stability, as the walker must be repositioned after each step to ensure support. This increases fall risk, requiring the charge nurse to intervene to correct the technique and ensure the client’s safety during ambulation.
Choice C reason: Grasping the walker by the hand grips on the upper bars is correct, as it provides optimal control and balance. This standard technique supports safe mobility, and no intervention is required, as it adheres to proper walker use guidelines.
Choice D reason: Lifting the walker as it is moved forward is acceptable for lightweight or rolling walkers, depending on the client’s strength and model. While sliding is preferred for standard walkers, lifting is not inherently unsafe, so intervention is unnecessary unless improper execution is observed.

Choice A reason: Administering oxygen is premature without assessing the cause of chest heaviness. While hypoxia may occur in aneurysm rupture, stopping exertion reduces cardiovascular demand first, prioritizing safety in a client with an abdominal aortic aneurysm at risk for rupture.
Choice B reason: Having the client sit down is the priority, as chest heaviness may signal aneurysm instability. Rest reduces aortic wall stress and oxygen demand, preventing rupture or dissection, stabilizing the client for further assessment and intervention in this high-risk condition.
Choice C reason: Checking vital signs is important but secondary to stopping exertion. Chest heaviness suggests potential aneurysm rupture, and continued ambulation risks catastrophe. Sitting the client minimizes cardiovascular stress, allowing subsequent vital sign checks to guide further actions effectively.
Choice D reason: Notifying the provider is critical but not first. Chest heaviness requires immediate cessation of activity to reduce aortic pressure. Sitting stabilizes the client, allowing data collection (e.g., vital signs) before provider notification, ensuring urgent intervention for potential aneurysm complications.
