A left-handed nurse is preparing to perform a straight catheterization. What should the nurse do first?

The first step for the nurse before performing a straight catheterization should be to ensure patient safety and comfort by raising the bed to a comfortable height. This action is crucial as it helps prevent injury for both the patient and the nurse during the procedure. By adjusting the bed, the nurse can easily access the patient and perform the catheterization without straining themselves or the patient, leading to a more efficient and safe process.

While gathering supplies, washing hands, and obtaining consent are all essential parts of the catheterization process, they are typically done after establishing a secure working environment. Ensuring the bed is at a suitable height sets the stage for the subsequent steps, ensuring that the nurse can carry out the procedure effectively.
