A 5-year-old child with a history of a waddling gait and frequent falls is brought into the hospital for diagnostic testing.
When explaining the diagnostic testing to the parents, the nurse should provide information based on which understanding of the underlying disease pathology?

Choice A rationale:

Impaired physical mobility relative to muscle rigidity has the highest priority in the nursing care plan for a client diagnosed with Parkinson's disease. Parkinson's disease is characterized by motor symptoms such as muscle rigidity, bradykinesia, and postural instability. Impaired physical mobility can significantly impact a patient's ability to perform activities of daily living and maintain independence. Addressing this issue is crucial to enhance the patient's quality of life and prevent complications such as falls.

Choice B rationale:

While the risk for aspiration relative to muscle weakness is a valid concern in Parkinson's disease, impaired physical mobility takes precedence as it directly affects the patient's ability to move, ambulate, and perform daily activities. Addressing mobility issues is fundamental to maintaining overall functioning and independence.

Choice C rationale:

The risk for constipation relative to immobility is important to address, but it is not the highest priority. Impaired physical mobility can lead to multiple complications, including constipation. However, improving mobility should be the primary focus to prevent a wide range of issues associated with Parkinson's disease.

Choice D rationale:

Self-care deficit relative to motor disturbance is a concern in Parkinson's disease, but it is not the highest priority. Impaired physical mobility directly impacts a patient's ability to engage in self-care activities. By addressing mobility issues first, the nurse can facilitate the patient's ability to perform self-care tasks more independently in the long run.

Choice A rationale:

Systemic autoimmune vasculopathy is not a typical underlying disease pathology associated with a waddling gait and frequent falls in a 5-year-old child. This choice is not relevant to the symptoms described.

Choice B rationale:

Autonomic neuropathy may manifest with a variety of symptoms, including autonomic dysregulation, but it is not a common underlying pathology leading to a waddling gait and frequent falls in a child. This choice is not relevant to the symptoms described.

Choice C rationale:

Impaired neuron function can result in various neurological symptoms, but it does not specifically explain the waddling gait and frequent falls in a 5-year-old child. This choice is not relevant to the symptoms described.

Choice D rationale:

Muscle fiber degeneration is the most appropriate explanation for the symptoms of a waddling gait and frequent falls in a 5-year-old child. These symptoms are indicative of a neuromuscular disorder known as Duchenne muscular dystrophy (DMD), which involves progressive muscle weakness and degeneration. DMD is characterized by the loss of muscle fibers and is a common cause of a waddling gait and falls in affected children. Therefore, choice D is the correct answer based on the understanding of the underlying disease pathology.
