Final answer:
The nurse should review the medication administration record (MAR) and ensure that the client is receiving the appropriate medications for myasthenia gravis.
Step-by-step explanation:
Myasthenia gravis is an autoimmune disorder that causes muscle weakness due to the blockage of acetylcholine receptors on the neuromuscular junction. When reviewing the medication administration record (MAR) of the adult client with myasthenia gravis, the nurse should pay attention to the medications being administered to the client.
In the case of myasthenia gravis, the most common treatment involves medications that counter the effects of the mutant gene or suppress the immune system. The nurse should ensure that the client is receiving the appropriate medications as prescribed, and monitor the client for any adverse effects or changes in symptoms.
