Chapter 30: The Child with Neuromuscular or Muscular Dysfunction - Nurselytic

Correct Answer: D

Rationale: Neonatal encephalopathy, often from unknown prenatal causes, is implicated in about 80% of CP cases, particularly in term and preterm infants. CNS diseases, birth asphyxia, and cerebral trauma contribute but are less common causes.

Correct Answer: C

Rationale: Spastic CP features hypertonicity and poor posture, balance, and coordination control due to increased muscle tone and stretch reflexes. Athetosis and dystonia characterize dyskinetic CP, tremors suggest other disorders, and wide-based gait is typical of ataxic CP.

Correct Answer: B

Rationale: Spastic CP, marked by initial hypotonia transitioning to hypertonicity, is the most common type. Ataxic, dyskinetic, and mixed types are less frequent, with spastic CP showing increased stretch reflexes and weakness.

Correct Answer: C

Rationale: Approximately 40% to 50% of children with CP have normal intelligence, with a wide range of cognitive outcomes. Severe physical impairment does not necessarily correlate with cognitive deficits, and many have minimal intellectual compromise.

Correct Answer: B

Rationale: Meticulous dental hygiene prevents gingivitis in CP, countering enamel defects, high-carbohydrate diets, and spasticity-related oral care challenges. Fluoride use is encouraged, and medications like phenytoin may require hygiene adjustments, not avoidance.
