A nurse is collecting data from an infant a large patent ductus arteriosus. Which of the following is clinical manifestations should the nurse expect?
Machine like murmur
Chronic hypoxemia
Cyanosis with crying
Weak pulse
The Correct Answer is A
A. Machine-like murmur.
This option is correct. A characteristic clinical manifestation of a large patent ductus arteriosus is a continuous "machine-like" murmur heard on auscultation. This murmur is typically heard best at the upper left sternal border and may radiate to the back.
B. Chronic hypoxemia.
Chronic hypoxemia is not typically a primary manifestation of a large PDA. While PDA can lead to increased pulmonary blood flow and potentially contribute to pulmonary congestion, chronic hypoxemia may not be a prominent feature unless complications such as heart failure develop.
C. Cyanosis with crying.
Cyanosis with crying is more commonly associated with cyanotic congenital heart defects such as tetralogy of Fallot. While PDA can contribute to cyanosis in certain circumstances, it is not typically a consistent clinical manifestation.
D. Weak pulse.
A weak pulse is not typically associated specifically with a large PDA. Infants with PDA may have bounding pulses due to increased blood flow through the ductus arteriosus.

Correct Answer is D
Explanation
A. Promote maternal-infant bonding: While promoting maternal-infant bonding is essential for the overall well-being of the newborn and family, it may not be the priority in this situation. The immediate focus is on medical management and preventing complications associated with the myelomeningocele.
B. Provide age-appropriate stimulation: Age-appropriate stimulation is important for newborn development, but in the case of a newborn with a myelomeningocele awaiting surgery, the priority is to minimize any potential risk of injury or infection to the exposed neural tissue.
C. Educate the parents about the defect: Education about the myelomeningocele and its long-term implications is crucial for the parents' understanding and ability to care for their child. However, while important, this may not be the priority at the immediate moment.
D. Maintain integrity of the sac: This is the priority nursing goal in caring for a newborn with a myelomeningocele awaiting surgery. The sac covering the exposed neural tissue must be carefully protected to prevent infection and further damage. Measures such as keeping the sac moist with sterile saline dressings and preventing trauma to the area are essential to maintain its integrity.

Correct Answer is D
Explanation
A. Flaccid paralysis of lower extremities:
Flaccid paralysis refers to a weakness or loss of muscle tone in the affected muscles, leading to decreased or absent movement. This finding is not typically associated with spina bifida occulta. Instead, it is more commonly seen in more severe forms of spina bifida, such as myelomeningocele, where there is significant involvement of the spinal cord and nerves.
B. Hip dislocation:
Hip dislocation can occur in individuals with myelomeningocele due to muscle weakness, abnormal muscle tone, and joint deformities associated with spinal cord defects. However, it is not typically associated with spina bifida occulta, which usually presents with less severe spinal cord involvement.
C. Hydrocephalus:
Hydrocephalus, characterized by the accumulation of cerebrospinal fluid within the brain, is a common complication of myelomeningocele due to disturbances in the flow and absorption of cerebrospinal fluid caused by the spinal defect. It is less commonly associated with spina bifida occulta, which typically involves a less severe spinal cord defect.
D. Dimple in sacral area:
This is the correct choice. A dimple, patch of hair, or birthmark in the lower back or sacral area is a common finding in spina bifida occulta. It occurs due to the incomplete closure of the spinal column during fetal development, leading to a small defect in the vertebrae. This is often a subtle manifestation of spina bifida occulta and may not cause significant symptoms or functional impairment.
