An adult client is admitted to the psychiatric unit because of a daily, complex handwashing ritual that takes two hours or longer to complete.

The client worries about staying clean and refuses to sit on any of the chairs in the day area.

This client's handwashing is an example of which clinical behavior?

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.

Choice A rationale:

Granulating tissue in a foot ulcer is a positive sign of wound healing, but it may not be directly related to the effectiveness of pregabalin in treating diabetic peripheral neuropathy. The primary goal of pregabalin in this context is to reduce pain and neuropathic symptoms.

Choice B rationale:

A reduced level of pain is the most relevant indicator of the effectiveness of pregabalin in treating diabetic peripheral neuropathy. Pregabalin is an antiepileptic medication used to manage neuropathic pain. A decrease in pain indicates that the medication is effectively managing the client's symptoms.

Choice C rationale:

Improved visual acuity is not directly related to the effectiveness of pregabalin in treating diabetic peripheral neuropathy. Pregabalin primarily targets neuropathic pain and sensory symptoms, not visual function.

Choice D rationale:

A full volume of pedal pulses is a positive sign of adequate circulation in the lower extremities, but it may not be directly related to the effectiveness of pregabalin in treating neuropathy symptoms. The primary goal of pregabalin in this context is pain management.
