What is the best action for a nurse when an infant exhibits bulging fontanels post-surgery?

When an infant exhibits bulging fontanels after surgery, it is an indication of increasing intracranial pressure, which can pose serious risks. Therefore, notifying the healthcare provider is the best course of action because they are equipped to assess and manage this potentially critical situation. Prompt communication allows for timely interventions, such as diagnostic imaging or adjustments in treatment, to ensure the safety and well-being of the infant.

In this context, calming the infant, teaching the parent about the procedure, or repositioning the infant may provide some comfort, but they do not address the underlying concern of intracranial pressure that could lead to serious complications if not managed properly. The immediate priority is to ensure that a qualified healthcare professional is aware of the concerning signs and can take the necessary actions to assess and treat the infant's condition effectively.
