,NR 328 Pediatric Mobility Disorders - Week 7 Comprehensive Exam 2026/2027 UPDATE –
Chamberlain College
1. A 4-year-old child with spastic cerebral palsy is scheduled for a selective dorsal rhizotomy.
Which outcome is the primary goal of this surgical procedure?
A. To improve cognitive functioning and speech
B. To correct underlying skeletal deformities
C. To prevent the development of hydrocephalus
D. To decrease muscle spasticity and improve motor function
Answer: D
Rationale: Selective dorsal rhizotomy (SDR) is a neurosurgical procedure intended to
reduce spasticity by severing overactive nerve fibers in the spinal cord, thereby improving
mobility.
2. When assessing a newborn for developmental dysplasia of the hip (DDH), the nurse
performs the Ortolani maneuver. Which finding indicates a positive Ortolani sign?
A. A distinct ‘clunk’ as the femoral head relocates into the acetabulum
B. Limited abduction of the affected hip
C. Asymmetry of the gluteal skin folds
D. A ‘click’ sound during passive range of motion
, Answer: A
Rationale: The Ortolani maneuver involves abducting the hip to reduce a dislocated
femoral head back into the acetabulum; a ‘clunk’ is felt as the head slips back into place.
3. A child with Duchenne Muscular Dystrophy (DMD) is transitioning to a wheelchair. Which
physiological finding is the most common cause of mortality in these patients?
A. Renal failure due to myoglobinuria
B. Pathological fractures of the long bones
C. Sepsis from chronic skin breakdown
D. Cardiopulmonary failure
Answer: D
Rationale: In DMD, the progressive weakening of the diaphragm and cardiac muscles leads
to respiratory failure or cardiomyopathy, which are the leading causes of death.
4. Which nursing intervention is prioritized for an infant born with an unrepaired
myelomeningocele?
A. Measuring head circumference daily to monitor for hydrocephalus
B. Applying a dry sterile dressing to the sac
C. Maintaining the infant in a prone position with hips abducted
D. Administering prophylactic antibiotics intravenously
Answer: C
