What should a nurse do if they observe an ulcerous area persisting after the cord falls off?

When a nurse observes an ulcerous area persisting after the umbilical cord falls off, it is important to recognize that this may indicate an underlying issue such as infection or improper healing that may require medical intervention. Notifying a physician is a crucial step in this scenario because the physician can provide a comprehensive evaluation of the area and determine if cautery or other treatments are necessary to prevent further complications.

Prompt recognition and management of ulceration is essential in neonates since their skin is particularly sensitive, and untreated issues can lead to more significant problems. Cautery can be utilized to stop any active bleeding or to assist in the proper healing of the tissue. This proactive approach helps to ensure the infant's health and promotes healing.

Other options such as applying antibiotic ointment or waiting for further observation may not adequately address any underlying issues. Continuing normal care procedures without addressing a persisting ulcer would not be appropriate either, as it neglects the potential need for more targeted intervention.
