What action should a nurse take to maintain sterility while inserting an indwelling urinary catheter?

Maintaining sterility during the insertion of an indwelling urinary catheter is crucial to prevent infections. Raising the bedside table to waist level is considered the most appropriate action because it allows the nurse to work comfortably and access sterile supplies without bending over too far, which can increase the risk of contamination. This position also helps ensure that the sterile field is easily reachable and visible, further promoting a clean technique.

When the bedside table is at waist height, the nurse can maintain a proper ergonomic position, which aids in focus and reduces the risk of accidental contamination. This is especially important when handling sterile equipment and supplies, as any foreign matter may compromise the sterile field.

Lowering the bedside table to knee level would make it awkward to reach for supplies and could lead to unintentional breaches in sterility. Positioning the client on their back is standard for catheter insertion, but it doesn't directly address the issue of maintaining a sterile field around the supplies. Covering the bedside table with a sterile cloth, while it may seem helpful, might not be as effective in maintaining the entire sterile field as ensuring that the working level is optimal for the procedure.
