What is the first step to take when casting a patient with an open ulcer?

Prioritizing hygiene is crucial when dealing with a patient who has an open ulcer. Putting on gloves is the first essential step to prevent the introduction of bacteria or contaminants into the ulcer, which could lead to infection or complications. Gloves serve as a barrier that protects both the healthcare provider and the patient during the casting process.

Following proper sanitation practices by wearing gloves ensures that any subsequent actions taken, such as positioning the foot or marking the ulcer, occur in a safe environment. It underscores the importance of infection control in clinical practice, particularly when working with vulnerable patients who have compromised skin integrity.
