The nurse is conducting a neurologic assessment on a client brought to the
emergency room after a motor vehicle accident. While assessing the client's
response to pain, the client pulls his arms upward and inward. The nurse
recognizes that this response represents an injury to what part of the brain?
1. Frontal lobe
2. Midbrain
3. Pons
4. Brainstem
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.

What are the reasons for performing a lumbar puncture on a client? Select all that
apply.
1.Confirming spinal cord injuries
2. Assessing sensory nerve problems
3. Measuring blood flow in many areas
4. Reading cerebrospinal fluid pressure
5. Injecting contrast medium for diagnostic study
4. Reading cerebrospinal fluid pressure
5. Injecting contrast medium for diagnostic study
A lumbar puncture is the insertion of a spinal needle into the subarachnoid space
between the third and fourth lumbar vertebrae; it can be used to obtain
cerebrospinal fluid readings with a manometer. Using a lumbar puncture, contrast
medium or air is injected for diagnostic study. Evoked potentials measure the
electrical signals to the brain generated by sound, light, or touch, and are used to
confirm neurologic conditions like spinal cord injuries and multiple sclerosis.
Evoked potentials are also used to assess sensory nerve problems. Cerebral blood
flow evaluation is used to measure blood flow in many areas using radioactive
substances.
A nurse completes an admission assessment on a client who is diagnosed with
myasthenia gravis. Which clinical finding is the nurse most likely to identify?
1. Problems with cognition
2. Difficult swallowing saliva
3. Intention tremors of the hands
4. Nonintention tremors of the extremities
2. Difficulty swallowing saliva
