Chapter 36 : Introduction to the Nervous System Questions
Question 1 of 5
The nurse is caring for a client newly diagnosed with multiple sclerosis who is overwhelmed by learning about the disease. The client indicates understanding that there is a disruption in the covering of axons but does not remember what the covering is called. What should the nurse tell the client?
Correct Answer: C
Rationale: Myelin is a fatty substance that covers some axons in the CNS and PNS. The nurse would be most correct in answering the question and then, if the client is tired, following up at the next meeting. It would also be appropriate to provide literature for the client to review at leisure. Discounting the client's need to know information about the disease process is belittling. Telling the client that more research needs to be done discounts the valuable information which is known.
Question 2 of 5
A client is waiting in a triage area to learn the medical status of family members following a motor vehicle accident. The client is pacing, taking deep breaths, and handwringing. Considering the effects in the body systems, what does the nurse anticipate the liver will do?
Correct Answer: B
Rationale: When the body is under stress, the sympathetic nervous system is activated to ready the body for action. The effect of the body is to mobilize stored glycogen to glucose to provide additional energy for body action.
Question 3 of 5
The nurse is performing the physical examination of a client with a suspected neurologic disorder. In addition to assessing other parts of the body, the nurse should assess for neck rigidity. Which method should help the nurse assess for neck rigidity correctly?
Correct Answer: C
Rationale: The neck is examined for stiffness or abnormal position. The presence of rigidity is assessed by moving the head and chin toward the chest. The nurse should not maneuver the neck if a head or neck injury is suspected or known. The neck should also not be maneuvered if trauma to any part of the body is evident. Moving the head toward the sides or pressing the bones on the neck will not help assess for neck rigidity correctly. While assessing for neck rigidity, sensation at the neck area is not assessed.
Question 4 of 5
The critical care nurse is giving end-of-shift report on a client. The nurse uses the Glasgow Coma Scale (GCS) to assess the level of consciousness (LOC) of a female client and reports to the oncoming nurse that the client has an LOC of 6. What does an LOC score of 6 in a client indicate?
Correct Answer: A
Rationale: The GSC is used to measure the LOC. The scale consists of three parts: eye opening response, best verbal response, and best motor response. A normal response is 15. A score of 7 or less is considered comatose.
Therefore, a score of 6 indicates the client is in a state of coma and not in any other state such as stupor or somnolence. The evaluations are recorded on a graphic sheet where connecting lines show an increase or decrease in the LOC.
Question 5 of 5
A client presents to the emergency department status postseizure. The health care provider wants to measure CSF pressure. What test might be ordered on this client?
Correct Answer: A
Rationale: Changes in CSF occur in many neurologic disorders. A lumbar puncture (spinal tap) is performed to obtain samples of CSF from the subarachnoid space for laboratory examination and to measure CSF pressure. Echoencephalography records the electrical impulses generated by the brain. Nerve conduction studies measure the speed with which the nerve impulse travels along the peripheral nerve. Electromyography studies the changes in the electrical potential of muscles and the nerves supplying the muscles.
