PEPU TEST 5
Terms in this set (55)
Ada Zontor, a 60-year-old bookkeeper, is a client with the neurological group where you practice nursing. Mrs. Zontor has been exhibiting neurological symptoms for several weeks and the neurologist is admitting her to hospital for extensive testing. Since diagnostics have not yet revealed the cause of her difficulties, which of her following comments would indicate the need for further client education?
a) There are several types of tests to see what's causing the tingling in my fingers and toes.
b) All of her comments indicate need for further client education.
c) It's good to know the continual tingling in my fingers and toes is not connected with my nervous system!
d) I need to be careful with my allergy to seafood!
C, The nervous system consists of the brain, spinal cord, and peripheral nerves.
A nurse is preparing a client for lumbar puncture. The client has heard about post-lumbar puncture headaches and asks how to avoid having one. The nurse tells the client that these headches can be avoided by doing which of the following after the procedure?
a) "Remain NPO for 6 hours."
b) "Ambulate as soon as possible."
c) "Remain prone for 2 to 3 hours."
d) "Remain on bedrest for 3 days."
C,The headache is caused by cerebral spinal fluid (CSF) leakage at the puncture site. The supply of CSF in the cranium is depleted so that there is not enough to cushion and stabilize the brain. When the client assumes an upright position, tension and stretching of the venous sinuses and pain-sensitive structures occur. The headache may be avoided if the client remains prone for 2 to 3 hours after the procedure. Drinking plenty of fluids will help in replacing the CSF. Hydration is important for replacement of the CSF lost so remaining NPO is not an option unless it is for other reasons, then IV fluid replacement will be important. Ambulating right away will make the possibility of a headache more likely. It is not necessary to remain on bedrest for more than a few hours, unless a headache has occurred; then bedest for overnight is usually sufficient
Which lobe of the brain is responsible for concentration and abstract thought?
C, The major functions of the frontal lobe are concentration, abstract thought, information storage or memory, and motor function. The parietal lobe analyzes sensory information such as pressure, vibration, pain, and temperature. The occipital lobe is the primary visual cortex. The temporal lobe contains the auditory receptive areas located around the temples.
Lower motor neuron lesions cause
a) no muscle atrophy.
b) hyperactive and abnormal reflexes.
c) flaccid muscle paralysis.
d) increased muscle tone.
C, Lower motor neuron lesions cause flaccid muscle paralysis, muscle atrophy, decreased muscle tone, and loss of voluntary control. Upper motor neuron lesions cause increased muscle tone. Upper motor neuron lesions cause no muscle atrophy. Upper motor neuron lesions cause hyperactive and abnormal reflexes.
A high school soccer player sustained five concussions before she was told that she should never play contact sports again. After her last injury, she began experiencing episodes of double vision. She was told that she had most likely incurred damage to which cranial nerve?
a) V (Trigeminal)
b) VI (Abducens)
c) IV (Trochlear)
d) VII (Facial)
B, The abducens cranial nerve supports movement of the eye laterally. Damage to the nerve can cause double vision.
What part of the brain controls and coordinates muscle movement?
d) Brain stem
A, The cerebellum, which is located behind and below the cerebrum, controls and coordinates muscle movement. Options B, C ,and D are incorrect
A patient has difficulty interpreting his awareness of body position in space. Which lobe is most likely to be damaged?
A, The parietal lobe is the primary sensory cortex. It is essential to a person's awareness of his body in space, as well as orientation in space and spatial relations.
The sympathetic and parasympathetic nervous systems have a direct affect on the circulatory system. Stimulation of the parasympathetic nervous system (PNS) causes which of the following?
a) Blood vessels in the heart muscle to dilate
b) Heartbeat to decrease
c) Blood pressure to increase
d) Blood vessels in the skeletal muscles to dilate
B,The parasympathetic nervous system has a constricting effect on the blood vessels in the heart and skeletal muscles; the heartbeat and blood pressure will decrease
Low levels of the neurotransmitter serotonin lead to which of the following disease processes?
c) Parkinson's disease
d) Myasthenia gravis
A A decrease of serotonin leads to depression. A decrease in the amount of acetylcholine causes myasthenia gravis. Parkinson's disease is caused by a depletion of dopamine. Decreased levels of GABA may cause seizures.
The critical care nurse is giving report on a client they are caring for. The nurse uses the Glasgow Coma Scale (GCS) to assess the level of consciousness (LOC) of a female client and reports to the on-coming nurse that the client has an LOC of 6. What does an LOC score of 6 in a client indicate?
D, 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
During recovery from a stroke, a client is given nothing by mouth to help prevent aspiration. To determine when the client is ready for a liquid diet, the nurse assesses the client's swallowing ability once per shift. This assessment evaluates:
a) cranial nerves I and II.
b) cranial nerves IX and X.
c) cranial nerves III and V.
d) cranial nerves VI and VIII.
Swallowing is a motor function of cranial nerves IX and X. Cranial nerves I, II, and VIII don't possess motor functions. The motor functions of cranial nerve III include extraocular eye movement, eyelid elevation, and pupil constriction. The motor function of cranial nerve V is chewing. Cranial nerve VI controls lateral eye movement.
A patient comes to the emergency department with severe pain in the face that was stimulated by brushing the teeth. What cranial nerve does the nurse understand can cause this type of pain?
B, The trigeminal nerve (cranial nerve V) innervates the forehead, cheeks, and jaw, so pain in the face elicited when brushing the teeth would most likely involve this nerve.
Upper motor neuron lesions cause
a) flaccid paralysis.
b) absent or decreased reflexes.
c) no muscle atrophy.
d) decreased muscle tone.
C,Upper motor neuron lesions do not cause muscle atrophy but do cause loss of voluntary control. Lower motor neuron lesions cause decreased muscle tone. Lower motor neuron lesions cause flaccid paralysis. Lower motor neuron lesions cause absent or decreased reflexes
Working hard to memorize the functions of the cranial nerves is a typical part of nursing school. Not only is it important to correlate the proper nerve number and name, but including the proper function makes this task quite a challenge! Which cranial nerves are enabling you to read this question?
d) All options are correct
D,The Oculomotor (III), Abducens (VI) and Trochlear (IV) nerves all work within the functional realm of the eyes. Don't forget the Optic (II) nerve!
In the divisions of the nervous systems, the basic structure is the neuron. The function of the neuron is determined by the direction of impulse transmission. Which part of the neuron is responsible for conducting impulses away from the cell body?
c) Efferent nerve fibers
d) Afferent nerve fibers
C, An axon is a nerve fiber that projects and conducts impulses away from the cell body. It is therefore called an efferent ("away from") nerve fiber
