2. Midbrain Decorticate posturing [1] [2] [3] is a sign of significant deterioration in a client's neurologic status and is manifested by rigid flexing of elbows and wrists. This can represent an injury to the midbrain. Damage to the frontal lobe would affect motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, and social and sexual behavior. The pons (which is part of the brainstem) and brainstem help control breathing and heart rate, vision, hearing, sweating, blood pressure, digestion, alertness, sleep, and sense of balance. Damage to this area would manifest itself as abnormal responses in the above listed areas. Which clinical finding is the nurse most likely to identify on a client who is diagnosed with myasthenia gravis?Single fiber electromyography (EMG), considered the most sensitive test for myasthenia gravis, detects impaired nerve-to-muscle transmission.
Which cranial nerve emerges from the client's medulla?Cranial nerves IX (glossopharyngeal), X (vagus), XI (accessory), and XII (hypoglossal) emerge from the medulla, as do portions of cranial nerves VII (facial) and VIII (acoustic). Damage to these nerves causes impaired swallowing, inability to shrug shoulders, and loss of the gag reflex.
