A nurse is noting from a client's neurologic assessment findings that the client's motor impulses are interrupted from the brain to the spinal cord. It also appears that the client lacks sensory impulses from the peripheral sensory neurons to the brain. Which area has the deficit? -midbrain -medulla oblongata -pons -subarachnoid space

-medulla oblongata The medulla oblongata lies below the pons and transmits motor impulses from the brain to the spinal cord, and sensory impulses from the peripheral sensory neurons to the brain. The pons is part of the brainstem. The midbrain forms the forward part of the brainstem and connects the pons and the cerebellum with the two cerebral hemispheres. The subarachnoid space lies between the pie matter and the arachnoids membrane.

Which neurons transmit impulses from the CNS? -Sensory -Neurilemma -Dendrites -Motor

-motor -Neurons are either sensory or motor. Sensory neurons transmit impulses to the CNS; motor neurons transmit impulses from the CNS. A membranous sheath called the neurilemma covers the myelin of axons in peripheral nerves. Dendrites are threadlike projections or fibers.

The nurse is caring for a comatose client. The nurse knows she should assess the client's motor response. Which method may the nurse use to assess the motor response? -observing the reaction of pupils to light -observing the client's response to painful stimulus -using the Romberg test -assessing the client's sensitivity to temperature, touch, and pain

-observing the client's response to painful stimulus The nurse evaluates motor response in a comatose or unconscious client by administering a painful stimulus. This action helps determine if the client makes an appropriate response by reaching toward or withdrawing from the stimulus. The Romberg test is used to assess equilibrium in a noncomatose client. Pupils are examined for their reaction to light to assess sensitivity in the third cranial (oculomotor) nerve. Sensitivity to temperature, touch, and pain is a test to assess the sensory function of the client and not motor response.

The nurse knows that reflexes in the body are centered where? -In the pons -In the medulla oblongata -In the spinal cord -In the midbrain

-In the spinal cord The spinal cord functions as a passageway for ascending sensory and descending motor neurons. Its two main functions are to provide centers for reflex action and to serve as a pathway for impulses to and from the brain. Reflex centers are not in the pons, the medulla, or the midbrain.

What part of the brain controls and coordinates muscle movement? 1- Cerebellum 2- Cerebrum 3- Midbrain 4- Brain stem

Cerebellum

A nurse is discussing a lumbar puncture with a nursing student who observed the procedure. The student noticed that the cerebrospinal fluid was blood tinged and asks what that means. The correct reply is which of the following? -"It can mean a traumatic puncture or a subarachnoid bleed." -"It can mean a bleed around the hypothalamus or damage from the needle." -"It can mean the spinal cord was damaged or a traumatic puncture." -"It can mean a subarachnoid bleed or damage to the spinal cord."

-"It can mean a traumatic puncture or a subarachnoid bleed." The needle is inserted below the level of the spinal cord, which prevents damage to the cord. The cerebral spinal fluid (CSF) should be clear and colorless. Pink or bloody CSF may indicate a subarachnoid bleed or local trauma from the puncture. The hypothalamus is located deep inside the brain and does not affect the color of the CSF.

The nurse is caring for a client who is undergoing single-photon emission computed tomography (SPECT). What is a potential side effect that this client may suffer? -Headache and pain in the neck -Claustrophobia -Allergic reaction to the imaging material -Allergic reaction to radioactive rays

-Allergic reaction to the imaging material

A patient is having a lumbar puncture and the physician has removed 20 mL of cerebrospinal fluid. What nursing intervention is a priority after the procedure? -Early ambulation -Have the patient lie flat for 6 hours. -Have the patient lie flat for 1 hour and then sit for 1 hour before ambulating. -Have the patient lie in a semi-Fowler's position with the head of the bed at 30º.

-Have the patient lie flat for 6 hours. Post-lumbar puncture headache may be avoided if a small-gauge needle is used and if the patient remains prone after the procedure. When more than 20 mL of CSF is removed, the patient is positioned supine for 6 hours (Bader & Littlejohns, 2010).

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? -Moving the head toward both sides -Lightly tapping the lower portion of the neck to detect sensation -Moving the head and chin toward the chest -Gently pressing the bones on the neck

-Moving the head and chin toward the chest 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 to be assessed.

The nurse is caring for a client in the clinic who has come in to have an EMG done. How would the nurse prepare the client for this test? -Tell the client the doctor will use fluoroscopy for this test. -Tell the client the test is painless. -Tell the client to expect some discomfort. -Tell the client they will have to lie flat afterwards.

-Tell the client to expect some discomfort. Tell the client to expect some discomfort when undergoing a lumbar puncture, myelogram, EMG, or nerve conduction studies. There is no fluoroscopy used for an EMG. It is not necessary to lie flat after an EMG.

During a routine physical examination to assess a client's deep tendon reflexes, a nurse should make sure to: -use the pointed end of the reflex hammer when striking the Achilles tendon. -support the joint where the tendon is being tested. -tap the tendon slowly and softly. -hold the reflex hammer tightly.

-support the joint where the tendon is being tested. The nurse should support the joint where the tendon is being tested to prevent the attached muscle from contracting. The nurse should use the flat, not pointed, end of the reflex hammer when striking the Achilles tendon. (The pointed end is used to strike over small areas, such as the thumb placed over the biceps tendon.) Tapping the tendon slowly and softly wouldn't provoke a deep tendon reflex response. The nurse should hold the reflex hammer loosely, not tightly, between the thumb and fingers so it can swing in an arc.

When learning about the nervous system, students learn that which nervous system regulates the expenditure of energy? 1- Parasympathetic 2- Central 3- Peripheral 4- Sympathetic

Sympathetic

Lower motor neuron lesions cause 1- increased muscle tone. 2- flaccid muscles. 3- no muscle atrophy. 4- hyperactive and abnormal reflexes.

flaccid muscles.

To assess a client's cranial nerve function, a nurse should assess: 1- hand grip. 2- orientation to person, time, and place. 3- arm drifting. 4- gag reflex.

gag reflex.

A nurse is preparing a client for a lumbar puncture and informs the client that the needle will be inserted into the subarachnoid space between L3 and L4 or L4 and L5. The client reports that she is worried about damage to her spinal cord. The appropriate response from the nurse is which of the following? -"The spinal cord ends at L1, so puncturing it is not possible." -"Damage to the spinal cord is a possibility." -"The physician is careful not to insert the needle far enough to reach the cord." -"The needle is not long enough to damage the cord."

-"The spinal cord ends at L1, so puncturing it is not possible." The needle is usually inserted into the subarachnoid space between the 3rd and 4th or 4th and 5th lumbar vertebrae. Because the spinal cord ends at the 1st lumbar vertebra, insertion of the needle below the level of the 3rd lumbar vertebra prevents puncture of the spinal cord.

The sympathetic and parasympathetic nervous systems have a direct effect on the circulatory system. Stimulation of the parasympathetic nervous system (PNS) causes which of the following? -Blood vessels in the heart muscle to dilate -Heartbeat to decrease -Blood pressure to increase -Blood vessels in the skeletal muscles to dilate

-Blood vessels in the heart muscle to dilate 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.

Which cranial nerve is responsible for facial sensation and corneal reflex? -Oculomotor -Vestibulocochlear -Facial -Trigeminal

-Trigeminal The trigeminal (V) cranial nerve is also responsible for mastication. The oculomotor (III) cranial nerve is responsible for the muscles that move the eye and lid, pupillary constriction, and lens accommodation. The vestibulocochlear (VII) cranial nerve is responsible for hearing and equilibrium. The facial nerve is responsible for salivation, tearing, taste, and sensation in the ear.

The nurse is doing an initial assessment on a patient recently admitted to the unit with a diagnosis of cerebrovascular accident (CVA).

The brain stem holds the medulla oblongata. What is the function of the medulla oblongata? -transmits sensory impulses from the brain to the spinal cord -controls striated muscle activity in blood vessel walls -controls parasympathetic nerve impulses in the pons -transmits motor impulses from the brain to the spinal cord

-transmits motor impulses from the brain to the spinal cord The medulla oblongata lies below the pons and transmits motor impulses from the brain to the spinal cord and sensory impulses from peripheral sensory neurons to the brain. The medulla contains vital centers concerned with respiration, heartbeat, and vasomotor activity (the control of smooth muscle activity in blood vessel walls).

A client undergoes a scheduled electroencephalogram (EEG). Which of the following post-procedure activities should the nurse carry out for the client? -Allow the client to rest and shampoo the client's hair. -Provide the client with adequate caffeine-rich drinks. -Measure the level of consciousness (LOC) of the client. -Measure the heart and the pulse rate.

-Allow the client to rest and shampoo the client's hair. After an EEG, the nurse should ensure rest for the sleep-deprived client and shampoo the client's hair to remove the glue used to affix electrodes to the scalp. The client is advised not to take sedative drugs and caffeine-related drinks before the EEG, and there is no reason to provide the client with them after the test. The nurse should not measure the LOC, the heart rate, or the pulse rate of the client unless advised by the physician.

Which diagnostic procedure would the nurse anticipate performing first if the goal was to obtain a thin "slice" of a muscular body area? -Computed tomography (CT) -Magnetic resonance imaging (MRI) -Positron emission tomography (PET) -Single-photon emission computed tomography (SPECT)

-Computed tomography (CT) A computer tomography scan uses x-rays and computer analysis to produce three-dimensional views of cross sections, or "slices," of the body. An MRI uses radiofrequency waves to produce images of tissue. PET scans use radioactive substances to examine metabolic activity and organ involvement. SPECT is an imaging tool that examines cerebral blood flow.

The nurse is educating a group of people newly diagnosed with migraine headaches. What information should the nurse include in the educational session? Select all that apply. 1- Keep a food diary. 2- Maintain a headache diary. 3- Sleep no more than 5 hours at a time. 4- Exercise in a dark room. 5- Use St. John's Wort.

1- Keep a food diary. 2- Maintain a headache diary.

A client suspected of having a distortion of cerebral arteries and veins is scheduled for a cerebral angiography. What would the nurse tell the client about the upcoming test? -That sedatives, coffee, tea, and soft drinks that contain caffeine will be withheld for at least 8 hours before the test to avoid affecting the diagnostic findings. -The client will have to stay in a dark quiet room. -Contrast will be given and a rapid sequence of radiographs will be taken. -The client will have to shampoo his or her hair.

-Contrast will be given and a rapid sequence of radiographs will be taken. A radiopaque dye is injected into the right or left carotid artery, the brachial artery, or the femoral artery. A rapid sequence of radiographs is taken as the dye circulates through the cerebral arteries and veins. For cerebral angiography options A, B, and D do not apply.

Damage to which area of the brain results in receptive aphasia? -Parietal lobe -Occipital lobe -Temporal lobe -Frontal lobe

-Temporal lobe The temporal lobe contains the auditory association area. If the area is damaged in the dominant hemisphere, the client hears words but doesn't know their meanings. Damage to the parietal lobe affects the client's ability to identify special relationships with the environment. When damaged, the occipital lobe affects visual associations. The client can visualize objects but can't identify them. The frontal lobe acts as a storage area for memory.

A nurse is working in an outpatient studies unit administering neurological tests. The client is surprised that paste is used to secure an electroencephalogram and asks how it will be removed from the hair. With what substance does the nurse reply? -Acetone -A special soap -Shampoo -Warm water

-Shampoo Explanation: Shampoo is used to remove the paste, which attached the electrodes to the head. Acetone is not used on the hair. There is no special soap needed. More than warm water is needed to lift and remove the paste.

A client is admitted to an acute care facility with a suspected dysfunction of the lower brain stem. The nurse should monitor this client closely for: -hypoxia. -fever. -visual disturbance. -gait alteration.

-hypoxia. Lower brain stem dysfunction alters bulbar functions, such as breathing, talking, swallowing, and coughing. Therefore, the nurse should monitor the client closely for hypoxia. Temperature control, vision, and gait aren't lower brain stem functions.

A primary nursing assessment for a patient who has sustained a fracture involving the basilar skull is inspection for: 1- Leakage of CSF from the nose. 2- Ecchymosis of the mastoid process of the temporal bone. 3- Leakage of CSF from the ear. 4- Vomiting and headaches due to increased intracranial pressure.

Leakage of CSF from the ear.

Which neurotransmitter demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways? 1- Enkephalin 2- Norepinephrine 3- Acetylcholine 4- Serotonin

Serotonin

A 53-year-old man presents to the emergency department with a chief complaint of inability to form words, and numbness and weakness of the right arm and leg. Where would you locate the site of injury? 1- Left frontoparietal region 2- Right frontoparietal region 3- Left basal ganglia 4- Left temporal region

Left frontoparietal region

A client is weak and drowsy after a lumbar puncture. The nurse caring for the client knows that what priority nursing intervention should be provided after a lumbar puncture? 1- Administer antihistamines to the client. 2- Provide adequate caffeine-rich drinks to the client. 3- Assess the level of consciousness (LOC) and the pupil response of the client. 4- Position the client flat for at least 3 hours.

Position the client flat for at least 3 hours.

A client is scheduled for an EEG. The client asks about any diet-related prerequisites before the EEG. Which diet-related advice should the nurse provide to the client? 1- Avoid eating food at least 8 hours before the test. 2- Include an increased amount of minerals in the diet. 3- Decrease the amount of minerals in the diet. 4- Avoid taking sedative drugs or drinks that contain caffeine for at least 8 hours before the test.

Avoid taking sedative drugs or drinks that contain caffeine for at least 8 hours before the test.
