Final answer:
A nurse would expect to see clinical manifestations of flaccid paralysis, muscle atrophy, fasciculations, decreased muscle tone, and absent or decreased tendon reflexes in a client with a lower motor neuron lesion, due to the disruption of nerve signals leading to neurological impairment.
Step-by-step explanation:
In the context of a lower motor neuron lesion, the classic clinical manifestations a nurse would expect to see are flaccid paralysis, muscle atrophy, fasciculations, decreased muscle tone, and absent or decreased tendon reflexes. Flaccid paralysis occurs due to the interruption of the nerve supply to the muscle. Muscle atrophy, or the loss of muscle mass, will follow if the lesion prevents nerve signals from reaching the muscle for a prolonged period. The spontaneous involuntary contraction of muscle fibers (fasciculations) are observed because the neurons are no longer modulated by higher nerve centers.
Furthermore, since the muscle tone is regulated by signals from the lower motor neurons, any damage can lead to decreased tone. Additionally, tendon reflexes, which are mediated by intact lower motor neuron pathways, will be absent or decreased due to the disruption in the reflex arc.
In sum, if a client has a lower motor neuron lesion, a nurse would typically see signs of neurological impairment localized to the affected area controlled by the damaged neurons. Muscle weakness and lack of reflexes are typical prominent features. It's crucial for nurses and healthcare providers to recognize these symptoms promptly for accurate diagnosis and intervention.
