What should a nurse do first when preparing for straight catheterization with a dominant left hand?

When preparing for straight catheterization, the initial step involves ensuring a safe and ergonomic working environment for the nurse. Raising the bed to a comfortable height is crucial because it allows the nurse to maintain a good posture during the procedure, reducing strain and ensuring stability while working in a delicate area. This adjustment also facilitates access to the patient's genital area and helps the nurse perform the procedure safely and effectively without back strain or awkward positioning.

After ensuring the bed is at a suitable height, the nurse can proceed with gathering sterile supplies, washing hands, and preparing the catheter insertion area, all of which are essential steps in maintaining sterility and patient safety during the catheterization process. However, establishing a proper working environment comes first to promote efficiency and effectiveness in the procedure.
