Final answer:
The major nursing intervention for an infant with myelomeningocele is timely surgical closure of the spinal opening to prevent further damage and infection. Postoperative care and management of neurological symptoms are crucial, and proper medical attention can result in a normal life expectancy for affected individuals.
Step-by-step explanation:
A major nursing intervention for an infant born with myelomeningocele, a severe form of spina bifida, is often surgical. Surgery to close the opening on the back or to remove the protruding sac is crucial. This procedure should be performed as early as possible to improve the chances of preventing or limiting additional nerve damage and potential infections associated with the defect.
Post-surgery, nursing care will focus on managing symptoms, protecting the site from injury, and preventing complications. Although neurological damage may persist due to the involvement of the spinal nerves, early intervention and ongoing supportive care can help in handling the symptoms. Additionally, monitoring for potential late-onset complications associated with the spinal cord is essential for long-term management.
It's important to note that while spina bifida can lead to significant complications, with proper medical intervention and management, individuals with this condition can have a normal life expectancy.
