Assessment of Neurologic Function

Question 1

Question 1 Regular

A patient is brought to the ER following a motor vehicle accident in which he sustained head trauma. Preliminary assessment reveals a vision deficit in the patients left eye. The nurse should associate this abnormal finding with trauma to which of the following cerebral lobes?

Answer

Correct Answer: B Rationale: Vision deficits, particularly affecting one eye, are typically linked to damage in the occipital lobe, which is responsible for visual processing and interpretation. Trauma in this region can disrupt visual pathways. A: Temporal Vision deficits are not primarily associated with the temporal lobe, which mainly processes auditory information and aspects of memory rather than visual input. C: Parietal The parietal lobe focuses on sensory perception and coordination, not specifically visual processing; thus, it wouldn't account for a vision deficit in one eye. D: Frontal The frontal lobe is primarily involved in executive functions and motor control, rather than visual perception, making it an unlikely source of isolated vision deficits.

Question 2

Question 2 Regular

A patient scheduled for magnetic resonance imaging (MRI) has arrived at the radiology department. The nurse who prepares the patient for the MRI should prioritize which of the following actions?

Answer

Correct Answer: B Rationale: Removing all metal-containing objects is crucial before an MRI, as the magnetic field can attract metal, posing a safety risk and potentially interfering with the imaging process. A: Withholding stimulants 24 to 48 hours prior to exam does not directly impact MRI safety or effectiveness, as stimulant intake is not a primary concern in the imaging procedure. C: Instructing the patient to void prior to the MRI may enhance comfort but is not a priority compared to ensuring no metal is present in the scanning area. D: Initiating an IV line for administration of contrast is relevant only if contrast is needed; not all MRI scans require this, making it a lesser priority.

Question 3

Question 3 Regular

A gerontologic nurse planning the neurologic assessment of an older adult is considering normal, agerelated changes. Of what phenomenon should the nurse be aware?

Rationale

Reduction in cerebral blood flow. This phenomenon is a normal age-related change that affects older adults, leading to various neurological implications, including cognitive decline and slower processing speeds often observed in geriatric patients. A: Hyperactive deep tendon reflexes. This condition typically indicates neurological pathology rather than a normal aging change, as reflexes generally diminish with age rather than becoming hyperactive. C: Increased cerebral metabolism. Aging is associated with a decrease in metabolic activity in the brain, not an increase, which can impact overall cognitive functioning and energy utilization. D: Hypersensitivity to painful stimuli. While sensitivity may change, hypersensitivity is not a standard age-related phenomenon; instead, older adults may experience altered pain perception, often resulting in reduced sensitivity.

Question 4

Question 4 Regular

The nurse has admitted a new patient to the unit. One of the patients admitting orders is for an adrenergic medication. The nurse knows that this medication will have what effect on the circulatory system?

Answer

Correct Answer: B Rationale: Increased heart rate. Adrenergic medications stimulate the sympathetic nervous system, leading to enhanced cardiac output. This results in a faster heart rate, which is crucial for addressing various circulatory system needs during emergencies. A: Thin, watery saliva Stimulating the adrenergic system typically decreases saliva production, resulting in thicker saliva rather than thin and watery. C: Decreased BP Adrenergic medications generally increase blood pressure due to vasoconstriction and increased cardiac output, not a decrease in blood pressure. D: Constricted bronchioles Adrenergic medications primarily cause bronchodilation, not constriction, by relaxing airway smooth muscles, aiding in respiratory function.

Question 5

Question 5 Regular

A nurse is assessing reflexes in a patient with hyperactive reflexes. When the patients foot is abruptly dorsiflexed, it continues to beat two to three times before settling into a resting position. How would the nurse document this finding?

Answer

Correct Answer: C Rationale: Clonus. This finding describes a series of involuntary muscle contractions following a sudden stretch, indicating hyperactivity in the reflex arc, which can be observed when the foot is dorsiflexed. A: Rigidity. This term refers to increased muscle tone and resistance to passive movement, not the rhythmic contractions observed in the patient's foot after dorsiflexion. B: Flaccidity. This describes decreased muscle tone and weakness, contrasting with the vigorous contractions noted in the patient’s foot, indicating heightened reflex activity instead. D: Ataxia. This term refers to a lack of coordination and balance, which does not pertain to the rhythmic contraction pattern seen in hyperactive reflexes during the assessment.

Question 6

Question 6 Regular

The nurse is doing an initial assessment on a patient newly admitted to the unit with a diagnosis of cerebrovascular accident (CVA). The patient has difficulty copying a figure that the nurse has drawn and is diagnosed with visual-receptive aphasia. What brain region is primarily involved in this deficit?

Rationale

B: The parietal-occipital area is primarily involved in visual processing and integration, which explains the patient's difficulty in copying a figure. This region facilitates visual perception, essential for accurate reproduction of visual stimuli. A: Temporal lobe Primarily associated with auditory processing and language comprehension, the temporal lobe does not directly influence visual-motor coordination or the ability to replicate visual figures. C: Inferior posterior frontal areas These areas are linked to speech production and articulation, rather than visual processing, hence they do not account for the observed difficulty in copying a drawn figure. D: Posterior frontal area This region primarily governs motor functions and voluntary movements, which are not directly related to visual interpretation, thus failing to explain the patient's visual-receptive aphasia effectively.

Question 7

Question 7 Regular

What term is used to describe the fibrous connective tissue that hugs the brain closely and extends into every fold of the brains surface?

Answer

Correct Answer: D Rationale: D: Pia mater accurately describes the delicate fibrous connective tissue that closely adheres to the brain's surface, penetrating into its folds, providing essential support and nourishment to the brain. A: Dura mater refers to the tough outermost layer of the meninges, offering protection to the brain but lacking the intimate association and penetrative quality of the pia mater. B: Arachnoid denotes the middle layer of the meninges, which lies between the dura mater and pia mater, but does not directly contact the brain's surface or infiltrate its folds. C: Fascia refers to a band or sheet of connective tissue that surrounds muscles and organs, not specifically related to the protective layers enveloping the brain and spinal cord.

Question 8

Question 8 Regular

The nurse is caring for a patient with an upper motor neuron lesion. What clinical manifestations should the nurse anticipate when planning the patients neurologic assessment?

Rationale

Loss of voluntary control of movement. Upper motor neuron lesions disrupt the pathways that facilitate voluntary motor control, leading to clinical manifestations such as spasticity, weakness, and a significant decrease in the ability to initiate movement. A: Decreased muscle tone Spinal reflexes may remain intact; thus, muscle tone typically increases rather than decreases in upper motor neuron lesions, leading to spasticity rather than flaccidity. B: Flaccid paralysis This condition is characteristic of lower motor neuron lesions, where muscle tone is diminished, contrasting with upper motor neuron lesions that present with increased tone and spasticity. D: Slow reflexes Upper motor neuron lesions typically result in brisk reflexes due to hyperactive spinal reflexes, as the inhibitory signals from the brain are disrupted, leading to exaggerated responses.

Answer

Correct Answer: C Rationale: Loss of voluntary control of movement. Upper motor neuron lesions disrupt the pathways that facilitate voluntary motor control, leading to clinical manifestations such as spasticity, weakness, and a significant decrease in the ability to initiate movement. A: Decreased muscle tone Spinal reflexes may remain intact; thus, muscle tone typically increases rather than decreases in upper motor neuron lesions, leading to spasticity rather than flaccidity.

Question 9

Question 9 Regular

The nurse is admitting a patient to the unit who is diagnosed with a lower motor neuron lesion. What entry in the patients electronic record is most consistent with this diagnosis?

Rationale

D: Patient demonstrates an absence of deep tendon reflexes. Lower motor neuron lesions disrupt the connections between spinal cord and muscles, leading to diminished or absent reflexes. This aligns with the characteristic presentation of such lesions in patients. A: Patient exhibits increased muscle tone. Increased muscle tone is typical of upper motor neuron lesions, not lower motor neurons, which usually present with flaccidity and decreased tone. B: Patient demonstrates normal muscle structure with no evidence of atrophy. Lower motor neuron lesions often lead to muscle atrophy due to denervation. Normal muscle structure contradicts this hallmark sign of lower motor neuron damage. C: Patient demonstrates hyperactive deep tendon reflexes. Hyperactive reflexes indicate the presence of upper motor neuron lesions, as lower motor neuron issues typically result in reduced or absent reflexes, not heightened responses.

Question 10

Question 10 Regular

An elderly patient is being discharged home. The patient lives alone and has atrophy of his olfactory organs. The nurse tells the patients family that it is essential that the patient have what installed in the home?

Answer

Correct Answer: D Rationale: A smoke detector is essential for the patient, as atrophy of the olfactory organs impairs the ability to smell smoke, increasing the risk of undetected fires at home. A: Grab bars enhance safety in bathrooms but do not address the specific danger of fire hazards related to the patient’s olfactory impairment. B: Nonslip mats improve stability and prevent falls, yet they do not mitigate the risk posed by the patient's inability to detect smoke or fire. C: Baseboard heaters provide warmth but have no relevance to the patient’s olfactory issues or the critical need for fire detection in the home.

Question 11

Question 11 Regular

The patient in the ED has just had a diagnostic lumbar puncture. To reduce the incidence of a postlumbar puncture headache, what is the nurses most appropriate action?

Rationale

Position the patient prone. Keeping the patient in a prone position after a lumbar puncture minimizes cerebrospinal fluid leakage, thereby significantly reducing the likelihood of developing a postlumbar puncture headache, which is a common complication. B: Position the patient supine with the head of bed flat. While supine positioning is common, having the head flat does not effectively prevent headaches compared to the prone position. C: Position the patient left side-lying. This position does not provide the same benefits as being prone, failing to adequately reduce the risk of cerebrospinal fluid leakage after the procedure. D: Administer acetaminophen as ordered. Medication administration addresses symptoms rather than preventing the underlying cause of postlumbar puncture headaches, which is primarily linked to cerebrospinal fluid dynamics.

Question 12

Question 12 Regular

The nurse is conducting a focused neurologic assessment. When assessing the patients cranial nerve function, the nurse would include which of the following assessments?

Rationale

D: Assessment of gag reflex. This evaluation is crucial in determining the integrity of cranial nerves IX and X, which are responsible for swallowing and protecting the airway, thus indicating neurologic function. A: Assessment of hand grip. While important for evaluating motor function, hand grip primarily assesses peripheral nerve function rather than cranial nerve integrity, which is the focus of this assessment. B: Assessment of orientation to person, time, and place. This assessment evaluates cognitive function rather than specific cranial nerve function, making it less relevant in a focused neurologic assessment of cranial nerves. C: Assessment of arm drift. This test primarily assesses upper motor neuron function and does not specifically evaluate cranial nerve function, which is the main concern in this scenario.

Question 13

Question 13 Regular

A nurse is caring for a patient diagnosed with Mnires disease. While completing a neurologic examination on the patient, the nurse assesses cranial nerve VIII. The nurse would be correct in identifying the function of this nerve as what?

Answer

Correct Answer: D Rationale: D: Hearing and equilibrium. Cranial nerve VIII, also known as the vestibulocochlear nerve, is responsible for transmitting sound information and maintaining balance, both crucial for patients with Meniere's disease. A: Movement of the tongue. This function is attributed to cranial nerve XII, which controls the muscles of the tongue and is not related to hearing or balance. B: Visual acuity. Visual acuity is managed by cranial nerve II, which is responsible for transmitting visual information from the retina to the brain, unrelated to auditory functions. C: Sense of smell. The sense of smell is associated with cranial nerve I, which detects odors and has no connection to hearing or equilibrium mechanisms.

Question 14

Question 14 Regular

A patient exhibiting an uncoordinated gait has presented at the clinic. Which of the following is the most plausible cause of this patients health problem?

Rationale

Cerebellar dysfunction. This condition directly affects coordination and balance, leading to an uncoordinated gait. The cerebellum plays a crucial role in motor control, making it the most plausible cause in this scenario. B: A lesion in the pons. While lesions can impact coordination, they typically result in different symptoms not primarily characterized by an uncoordinated gait alone. C: Dysfunction of the medulla. The medulla mainly regulates autonomic functions and vital signs, which do not directly correlate with gait coordination issues, hence less likely to be the cause. D: A hemorrhage in the midbrain. This may lead to various neurological deficits, but uncoordinated gait is not a primary symptom associated with midbrain hemorrhages, making it less plausible.

Question 15

Question 15 Regular

The nursing students are learning how to assess function of cranial nerve VIII. To assess the function of cranial nerve VIII the students would be correct in completing which of the following assessment techniques?

Rationale

Test for air and bone conduction (Rinne test). Assessing cranial nerve VIII, also known as the vestibulocochlear nerve, involves evaluating hearing and balance. The Rinne test specifically measures auditory function by comparing air and bone conduction, making it the appropriate technique for this cranial nerve assessment. A: Have the patient identify familiar odors with the eyes closed. This technique assesses cranial nerve I, which is responsible for the sense of smell, not cranial nerve VIII. B: Assess papillary reflex. Evaluating the papillary reflex pertains to cranial nerves II and III, which are involved in vision and pupil response, thus unrelated to cranial nerve VIII's function. C: Utilize the Snellen chart. The Snellen chart is designed to test visual acuity associated with cranial nerve II, making it unsuitable for assessing the auditory capabilities of cranial nerve VIII.

Question 16

Question 16 Regular

A patient is being given a medication that stimulates her parasympathetic system. Following administration of this medication, the nurse should anticipate what effect?

Rationale

Constricted pupils. The stimulation of the parasympathetic system leads to the activation of the iris sphincter muscle, resulting in miosis or constricted pupils, which is a typical physiological response to such medications. B: Dilated bronchioles. Activation of the parasympathetic system typically causes bronchoconstriction, not dilation, which is contrary to the expected response associated with stimulation of this system. C: Decreased peristaltic movement. Stimulation of the parasympathetic system enhances digestive activity, including increased peristalsis, thereby contradicting the notion of decreased movement in the gastrointestinal tract. D: Relaxed muscular walls of the urinary bladder. The parasympathetic system promotes contraction of the bladder walls, facilitating urination, which directly opposes the idea of relaxation in this context.

Question 17

Question 17 Regular

A patient with lower back pain is scheduled for myelography using metrizamide (a water-soluble contrast dye). After the test, the nurse should prioritize what action?

Answer

Correct Answer: A Rationale: Positioning the patient with the head of the bed elevated 45 degrees helps reduce the risk of post-myelography headaches by facilitating the reabsorption of contrast dye from the subarachnoid space. B: Administering IV morphine sulfate to prevent headache may mask symptoms rather than address the underlying issue of potential headaches due to the procedure. C: Limiting fluids for the next 12 hours can lead to dehydration and hinder recovery, as adequate hydration is necessary after the use of contrast dye. D: Helping the patient perform deep breathing and coughing exercises, while beneficial for lung health, does not directly address the specific complications related to myelography.

Question 18

Question 18 Regular

A patient is having a fight or flight response after receiving bad news about his prognosis. What affect will this have on the patients sympathetic nervous system?

Rationale

C: Increase in the secretion of sweat. The fight or flight response activates the sympathetic nervous system, triggering heightened arousal and physiological changes, including increased sweat secretion to help regulate body temperature during stress. A: Constriction of blood vessels in the heart muscle. The sympathetic response typically causes dilation of blood vessels supplying muscles and constriction in non-essential areas, rather than constricting coronary vessels which supply the heart itself. B: Constriction of bronchioles. In stressful situations, the sympathetic nervous system promotes bronchodilation to enhance airflow and oxygen supply, countering the notion that bronchioles would constrict during a fight or flight response. D: Constriction of pupils. The sympathetic nervous system actually leads to pupil dilation to improve vision and increase awareness, opposing the idea that pupils would constrict during heightened emotional or physical stress.

Answer

Correct Answer: C Rationale: C: Increase in the secretion of sweat. The fight or flight response activates the sympathetic nervous system, triggering heightened arousal and physiological changes, including increased sweat secretion to help regulate body temperature during stress.

Question 19

Question 19 Multiple Choice

The nurse educator is reviewing the assessment of cranial nerves. What should the educator identify as the specific instances when cranial nerves should be assessed? Select all that apply.

Rationale

Cranial nerves should be assessed when the level of consciousness is decreased, brain stem pathology is present, or there is a peripheral nervous system disease affecting function. B: When level of consciousness is decreased. This situation indicates possible neurological impairment, necessitating cranial nerve assessment to evaluate brain function and identify potential issues. C: With brain stem pathology. Pathology in the brain stem can disrupt cranial nerve function, thus making their assessment crucial for understanding the extent of neurological damage. D: In the presence of peripheral nervous system disease. While this may affect nerve function, it specifically pertains to peripheral nerves rather than cranial nerves, which are not primarily involved. E: When a spinal reflex is interrupted. Spinal reflexes are mediated by the spinal cord, not cranial nerves, making this scenario unrelated to cranial nerve assessment.

A patient in the OR goes into malignant hyperthermia due to an abnormal reaction to the anesthetic. The nurse knows that the area of the brain that regulates body temperature is which of the following?

Rationale

The hypothalamus regulates body temperature. This area of the brain maintains homeostasis by detecting changes in body temperature and initiating responses such as sweating or shivering to restore balance. A: Cerebellum Coordinates voluntary movements and balance, but does not play a role in thermoregulation or body temperature control, which is essential during episodes like malignant hyperthermia. B: Thalamus Primarily functions as a relay station for sensory information and does not directly influence the mechanisms responsible for regulating body temperature in response to environmental changes. D: Midbrain Involved in various functions, including vision and hearing, but is not responsible for the regulation of body temperature, which is specifically managed by the hypothalamus.

Question 21

Question 21 Regular

The nurse is planning the care of a patient with Parkinsons disease. The nurse should be aware that treatment will focus on what pathophysiological phenomenon?

Rationale

Decreased availability of dopamine. In Parkinson's disease, the primary pathophysiological phenomenon is the loss of dopamine-producing neurons in the brain, which significantly affects motor control and leads to the characteristic symptoms of the disease. A: Premature degradation of acetylcholine. This option does not relate to Parkinson's, as the disorder primarily involves dopamine deficiency rather than issues with acetylcholine metabolism. C: Insufficient synthesis of epinephrine. While epinephrine is a neurotransmitter, it plays a minimal role in Parkinson's disease compared to the critical dysfunction of dopamine neurotransmission. D: Delayed reuptake of serotonin. Serotonin's reuptake is not central to Parkinson's pathophysiology, which focuses on dopamine deficits, making this option irrelevant to the disease's treatment strategy.

Question 26

Question 26 Regular

The nurse is caring for a patient who exhibits abnormal results of the Weber test and Rinne test. The nurse should suspect dysfunction involving what cranial nerve?

Rationale

B: Dysfunction involving the acoustic nerve is indicated by abnormal results in both the Weber and Rinne tests, which specifically assess auditory function and sound conduction, suggesting issues related to hearing. A: Trigeminal This nerve primarily manages facial sensation and mastication, lacking direct involvement in auditory testing, thus not correlating with the abnormal results observed in the Weber and Rinne tests. C: Hypoglossal Responsible for tongue movement, this nerve does not influence hearing or auditory perception, making it unrelated to the dysfunction indicated by the abnormal test results. D: Trochlear This nerve is involved in eye movement and does not pertain to auditory function, rendering it irrelevant in the context of the Weber and Rinne test abnormalities.

Question 27

Question 27 Regular

The nurse caring for an 80 year-old patient knows that she has a pre-existing history of dulled tactile sensation. The nurse should first consider what possible cause for this patients diminished tactile sensation?

Rationale

C: Age-related neurologic changes. Aging often results in a decline in sensory functions, including tactile sensation. This patient's age and history suggest that natural degenerative processes may significantly contribute to her diminished tactile perception. A: Damage to cranial nerve VIII. This cranial nerve primarily affects hearing and balance, not tactile sensation, making it an unlikely cause for the patient's sensory decline. B: Adverse medication effects. While medications can impact sensory perception, the patient’s age and pre-existing condition suggest that age-related changes are a more probable explanation for her diminished tactile sensation. D: An undiagnosed cerebrovascular accident in early adulthood. Such an event would likely have presented with more significant and noticeable neurological deficits, making it less plausible as a cause for her current sensory issues.

Question 28 Regular

A 72-year-old man has been brought to his primary care provider by his daughter, who claims that he has been experiencing uncharacteristic lapses in memory. What principle should underlie the nurses assessment and management of this patient?

Rationale

Thorough assessment is necessary because changes in cognition are always considered to be pathologic. This principle emphasizes the importance of evaluating cognitive changes in older adults to rule out underlying conditions that may require intervention. A: Loss of short-term memory is normal in older adults, but loss of long-term memory does not capture the complexity of cognitive decline and potential medical issues. B: Lapses in memory in older adults are considered benign only if they do not interfere with daily functioning, which does not account for potentially serious underlying conditions. C: Gradual increases in confusion accompany the aging process, yet this oversimplifies cognitive decline and overlooks the need for comprehensive evaluation to identify treatable causes.

A trauma patient in the ICU has been declared brain dead. What diagnostic test is used in making the determination of brain death?

Rationale

Electroencephalography (EEG) is the diagnostic test used in making the determination of brain death. This test measures electrical activity in the brain, revealing the absence of brain function, which is essential for confirming brain death in patients. A: Magnetic resonance imaging (MRI) Visualization of brain structure doesn’t assess brain activity, thus failing to provide necessary evidence for brain death determination, making it unsuitable for this specific diagnosis. C: Electromyelography (EMG) This test evaluates muscle and nerve function but does not measure brain activity or determine brain death, rendering it irrelevant for confirming the absence of brain function. D: Computed tomography (CT) CT scans focus on imaging the brain's anatomy and structures rather than assessing electrical brain activity, which is crucial for accurately diagnosing brain death.

Question 31

Question 31 Regular

A patient is scheduled for CT scanning of the head because of recent onset of neurologic deficits. What should the nurse tell the patient in preparation for this test?

Answer

Correct Answer: C Rationale: You will need to lie still throughout the procedure. This is essential for obtaining clear images of the brain during the CT scan, as any movement can lead to blurred results and misinterpretation of findings. A: No metal objects can enter the procedure room. While avoiding metal is important, the primary focus for the patient should be on remaining still during the scan. B: You need to fast for 8 hours prior to the test. Fasting is typically not required for a CT scan of the head, unlike some other imaging procedures involving contrast materials. D: There will be a lot of noise during the test. Although CT machines can be noisy, this is not a critical preparation point compared to the necessity of remaining motionless during the scan.

Question 32

Question 32 Regular

A patient for whom the nurse is caring has positron emission tomography (PET) scheduled. In preparation, what should the nurse explain to the patient?

Rationale

The patient will need to endure dizziness or lightheadedness. During a positron emission tomography (PET) scan, the introduction of radioactive tracers may lead to temporary sensations of dizziness or lightheadedness, which the nurse should prepare the patient for to ensure their comfort and understanding of the procedure. A: The test will temporarily limit blood flow through the brain. Blood flow limitation is not a typical concern in PET scans; rather, the focus is on imaging metabolic activity. B: An allergy to iodine precludes getting the radio-opaque dye. PET scans do not utilize iodine-based dyes; instead, they use different radioactive tracers unrelated to iodine allergies. C: The patient will need to endure loud noises during the test. PET scans are generally quiet procedures, focusing on imaging rather than producing significant noise, unlike some other imaging modalities.

A patient is scheduled for a myelogram and the nurse explains to the patient that this is an invasive procedure, which assesses for any lesions in the spinal cord. The nurse should explain that the preparation is similar to which of the following neurologic tests?

Rationale

A lumbar puncture. This procedure involves inserting a needle into the spinal canal, similar to a myelogram where contrast dye is introduced to visualize spinal lesions, necessitating comparable preparation steps. B: MRI This imaging technique does not involve invasive needle insertion or contrast preparation in the same manner as myelograms, focusing instead on magnetic resonance imaging without the same preparatory requirements. C: Cerebral angiography This procedure requires catheter insertion into blood vessels and specialized contrast, differing significantly from the spinal-focused preparation of a myelogram and not aligning with its invasive nature. D: EEG An electroencephalogram measures electrical activity in the brain using electrodes on the scalp, lacking the invasive characteristics of a myelogram and requiring no similar preparatory steps.

Question 34

Question 34 Regular

The physician has ordered a somatosensory evoked responses (SERs) test for a patient for whom the nurse is caring. The nurse is justified in suspecting that this patient may have a history of what type of neurologic disorder?

Rationale

Somatosensory evoked responses (SERs) testing is particularly relevant in cases of demyelinating diseases, as these conditions impair the transmission of sensory signals, revealing functional deficits in the nervous system. A: Hypothalamic disorder A hypothalamic disorder primarily affects functions like temperature regulation and hunger, not somatosensory pathways, making SERs less indicative of issues stemming from this part of the brain. C: Brainstem deficit While brainstem deficits can impact sensory processing, SERs are more specifically linked to demyelination, which affects peripheral and central pathways more directly than localized brainstem issues. D: Diabetic neuropathy Diabetic neuropathy involves peripheral nerve damage, which might not yield significant SER abnormalities, as these tests are more focused on central nervous system integrity and demyelination effects.

Question 36

Question 36 Regular

A patient is currently being stimulated by the parasympathetic nervous system. What effect will this nervous stimulation have on the patients bladder?

Rationale

The bladder contracts due to stimulation by the parasympathetic nervous system. This system promotes bladder muscle activity, facilitating the process of urination by encouraging the bladder to empty, thereby enhancing urinary function. A: The parasympathetic nervous system causes urinary retention. This option misrepresents the role of the parasympathetic system, which actually promotes bladder contractions rather than inhibiting urinary flow. B: The parasympathetic nervous system causes bladder spasms. While spasms may occur in certain conditions, the primary action of the parasympathetic system is to induce coordinated contractions, not spasms. C: The parasympathetic nervous system causes urge incontinence. Urge incontinence relates to an overactive bladder, but the parasympathetic system primarily aims to facilitate bladder contraction and control urination, not incontinence.

The nurse is performing a neurologic assessment of a patient whose injuries have rendered her unable to follow verbal commands. How should the nurse proceed with assessing the patients level of consciousness (LOC)?

Rationale

B: Assess the patients eye opening and response to stimuli. This approach effectively evaluates the patient's level of consciousness, providing crucial information on cognitive function and responsiveness, critical in cases of neurological impairment. A: Assess the patients vital signs and correlate these with the patients baselines. While vital signs are important, they do not directly assess consciousness or cognitive responsiveness in this scenario. C: Document that the patient currently lacks a level of consciousness. Documentation is necessary but does not actively assess or provide insight into the patient's current neurological status. D: Facilitate diagnostic testing in an effort to obtain objective data. Diagnostic testing may provide useful information but does not immediately evaluate the patient's current level of consciousness or responsiveness.

In the course of a focused neurologic assessment, the nurse is palpating the patients major muscle groups at rest and during passive movement. Data gleaned from this assessment will allow the nurse to describe which of the following aspects of neurologic function?

Rationale

Muscle tone. Assessing major muscle groups at rest and during passive movement specifically evaluates muscle tone, indicating the state of tension in the muscles, which reflects neurologic function. A: Muscle dexterity. This assessment does not measure fine motor skills or coordination, which are essential facets of dexterity, but rather focuses on the overall muscle tone at rest. C: Dysfunction of basal ganglia. While muscle tone can be influenced by basal ganglia function, this specific assessment does not directly diagnose or evaluate dysfunction in those brain structures. D: Motor symmetry. Although muscle tone can relate to symmetry, the assessment primarily targets the tension and state of muscles rather than comparing the symmetry of movements between sides.

During the performance of the Romberg test, the nurse observes that the patient sways slightly. What is the nurses most appropriate action?

Rationale

The patient successfully completed the Romberg test, as slight swaying can be a normal response, indicating the vestibular and proprioceptive systems are functioning, thus warranting documentation of the assessment's outcome. A: Facilitate a referral to a neurologist. No immediate neurological concerns necessitate such referral; slight swaying during the test often falls within normal limits without indicating a serious issue. B: Reposition the patient supine to ensure safety. The patient’s slight swaying does not indicate an immediate risk of falling or injury, making repositioning unnecessary in this context. D: Follow up by having the patient perform the Rinne test. The Rinne test assesses hearing, which is unrelated to the Romberg test outcomes, thus it does not provide relevant information for the current situation.
