For a client with a new diagnosis of myasthenia gravis, which manifestation should the nurse monitor for?

In myasthenia gravis, the primary manifestation that a nurse should monitor for is weakness. This neuromuscular disorder is characterized by weakness in the voluntary muscles due to the inability of nerve impulses to trigger muscle contractions effectively. The hallmark symptom of myasthenia gravis is fluctuating muscle weakness that typically worsens with activity and improves with rest.

Monitoring for this specific weakness is crucial as it can affect major muscle groups, including those controlling eye movements, facial expressions, chewing, swallowing, and even respiratory function. Identifying changes in the pattern and severity of weakness can help in the timely adjustment of treatment and interventions to enhance the client’s safety and quality of life.

Other potential manifestations like confusion or signs of increased intracranial pressure are not characteristic of myasthenia gravis, as this condition primarily affects the neuromuscular junction. Increased urinary output is also unrelated to the effects of myasthenia gravis, and while it may be observed in various other conditions, it is not a direct concern for a client diagnosed with this disorder.
