Silvestri NCLEX test 5

The nurse reviews the health care provider's (HCP) prescriptions for a client with Guillain-Barré syndrome. Which prescription written by the HCP should the nurse question? 1.Clear liquid diet 2.Bilateral calf measure 3.Monitor vital signs frequently 4.Passive range-of-motion (ROM) exercises

1 Rationale: Clients with Guillain-Barré syndrome have dysphagia. Clients with dysphagia are more likely to aspirate clear liquids than thick or semisolid foods. Passive ROM exercises can help prevent contractures, and assessing calf measurements can help detect deep vein thrombosis, for which these clients are at risk. Because clients with Guillain-Barré syndrome are at risk for hypotension or hypertension, bradycardia, and respiratory depression, frequent monitoring of vital signs is required.

A client with myasthenia gravis arrives at the hospital emergency department in suspected crisis. The health care provider plans to administer edrophonium to differentiate between myasthenic and cholinergic crises. The nurse ensures that which medication is available in the event that the client is in cholinergic crisis? 1.Atropine sulfate 2.Morphine sulfate 3.Protamine sulfate 4.Pyridostigmine bromide

1 Rationale: Clients with cholinergic crisis have experienced overdosage of medication. Edrophonium will exacerbate symptoms in cholinergic crisis to the point at which the client may need intubation and mechanical ventilation. Intravenous atropine sulfate is used to reverse the effects of these anticholinesterase medications. Morphine sulfate and pyridostigmine bromide would worsen the symptoms of cholinergic crisis. Protamine sulfate is the antidote for heparin.

The nurse in the neurological unit is monitoring a client for signs of increased intracranial pressure (ICP). The nurse reviews the assessment findings for the client and notes documentation of the presence of Cushing's reflex. The nurse determines that the presence of this reflex is obtained by assessing which item? 1.Blood pressure 2.Motor response 3.Pupillary response 4. Level of consciousness

1 Rationale: Cushing's reflex is a late sign of increased ICP and consists of a widening pulse pressure (systolic pressure rises faster than diastolic pressure) and bradycardia. Options 2, 3, and 4 are unrelated to monitoring for Cushing's reflex.

The nurse is caring for a client after a craniotomy and monitors the client for signs of increased intracranial pressure (ICP). Which finding, if noted in the client, would indicate an early sign of increased ICP? 1.Confusion 2.Bradycardia 3.Sluggish pupils 4.A widened pulse pressure

1 Rationale: Early manifestations of increased ICP are subtle and often may be transient, lasting for only a few minutes in some cases. These early clinical manifestations include episodes of confusion, drowsiness, and slight pupillary and breathing changes. Later manifestations include a further decrease in the level of consciousness, a widened pulse pressure, and bradycardia. Cheyne-Stokes respiratory pattern, or a hyperventilation respiratory pattern; pupillary sluggishness and dilatation appear in the late stages.

The nurse is performing a neurological assessment on a client and is assessing the function of cranial nerves III, IV, and VI. Assessment of which aspect of function by the nurse will yield the best information about these cranial nerves? 1.Eye movements 2.Response to verbal stimuli 3. Affect, feelings, or emotions 4. Insight, judgment, and planning

1 Rationale: Eye movements are under the control of cranial nerves III, IV, and VI. Level of consciousness (response to verbal stimuli) is controlled by the reticular activating system and both cerebral hemispheres. Feelings are part of the role of the limbic system and involve both hemispheres. Insight, judgment, and planning are part of the function of the frontal lobe in conjunction with association fibers that connect to other areas of the cerebrum.

A client with multiple sclerosis tells a home health care nurse that she is having increasing difficulty in transferring from the bed to a chair. What is the initial nursing action? 1. Observe the client demonstrating the transfer technique. 2. Start a restorative nursing program before an injury occurs. 3. Seize the opportunity to discuss potential nursing home placement. 4. Determine the number of falls that the client has had in recent weeks.

1 Rationale: Observation of the client's transfer technique is the initial intervention. Starting a restorative program is important but not unless an assessment has been completed first. Discussing nursing home placement would be inappropriate in view of the information provided in the question. Determining the number of falls is another important intervention, but observing the transfer technique should be done first.

A client has a cerebellar lesion. The nurse determines that the client is adapting successfully to this problem if the client demonstrates proper use of which item? 1.Walker 2.Slider board 3.Raised toilet seat 4. Adaptive eating utensils

1 Rationale: The cerebellum is responsible for balance and coordination. A walker would provide stability for the client during ambulation. Adaptive eating utensils may be beneficial if the client has partial paralysis of the hand. A raised toilet seat is useful if the client does not have the mobility or ability to flex the hips. A slider board is used in transferring a client from a bed to a stretcher or wheelchair.

An adult client has a diagnosis of hydrocephalus. The nurse plans care, knowing that this condition leads to more serious neurological consequences in adults as a result of closure of which structures? 1.Cranial sutures 2.Arachnoid villi 3.Foramen of Monro 4.Aqueduct of Sylvius

1 Rationale: The closure of cranial sutures during childhood prevents expansion of the cranial vault when hydrocephalus occurs in the adult. This leads to increased neurological changes with lesser degrees of hydrocephalus compared with hydrocephalus during early childhood. The other structures identified are associated with cerebrospinal fluid formation and circulation, but these do not close off.

The nurse caring for a client with a head injury is monitoring for signs of increased intracranial pressure. The nurse reviews the record and notes that the intracranial pressure (cerebrospinal fluid) is averaging 8 mm Hg. The nurse plans care, knowing that these results are indicative of which condition? 1.Normal condition 2.Increased pressure 3.Borderline situation 4. Compensating condition

1 Rationale: The normal intracranial pressure is 5 to 10 mm Hg. A pressure of 8 mm Hg is within normal range.

A client who is experiencing an inferior wall myocardial infarction has had a drop in heart rate into the range of 50 to 56 beats/minute. The client also is complaining of nausea. The nurse understands that these symptoms are caused by stimulation of which cranial nerve (CN)? 1. Vagus (CN X) 2.Hypoglossal (CN XII) 3. Spinal accessory (CN XI) 4. Glossopharyngeal (CN IX)

1 Rationale: The vagus nerve is responsible for sensations in the thoracic and abdominal viscera. It also is responsible for the decrease in heart rate because approximately 75% of all parasympathetic stimulation is carried by the vagus nerve. CN XII is responsible for tongue movement. CN XI is responsible for neck and shoulder movement. CN IX is responsible for taste in the posterior two thirds of the tongue, pharyngeal sensation, and swallowing.

The nurse is teaching a client with paraplegia measures to maintain skin integrity. Which instruction will be most helpful to the client? 1.Shift weight every 2 hours while in a wheelchair. 2.Change bed sheets every other week to maintain cleanliness. 3.Place a pillow on the seat of the wheelchair to provide extra comfort. 4. Use a mirror to inspect for redness and skin breakdown twice a week.

1 Rationale: To maintain skin integrity, the client should shift weight in the wheelchair every 2 hours and use a pressure relief pad. A pillow is not sufficient to relieve the pressure. While the client is in bed, the bottom sheet should be free of wrinkles and wetness. Sheets should be changed as needed and more frequently than every other week. The client should use a mirror to inspect the skin twice daily (morning and evening) to assess for redness, edema, and breakdown. General additional measures include a nutritious diet and meticulous skin care.

A nurse is evaluating the neurological status of a client. To assess the function of the limbic system, the nurse should gather data about which item? 1.Experience of pain 2.Affect or emotions 3.Response to verbal stimuli 4.Insight, judgment, and planning

2 Rationale: Affect and emotions are part of the role of the limbic system and involve both hemispheres of the brain. Pain is a complex experience involving several areas of the central nervous system. The response to verbal stimuli is part of the level of consciousness, which is under the control of the reticular activating system and both cerebral hemispheres. Insight, judgment, and planning are part of the functions of the frontal lobes of the brain in conjunction with association fibers connecting to other areas of the cerebrum.

The student nurse develops a plan of care for a client after a lumbar puncture. The nursing instructor corrects the student if the student documents which incorrect intervention in the plan? 1.Maintain the client in a flat position. 2.Restrict fluid intake for a period of 2 hours. 3.Assess the client's ability to void and move the extremities. 4.Inspect the puncture site for swelling, redness, and drainage.

2 Rationale: After the lumbar puncture the client remains flat in bed for at least 2 hours, depending on the health care provider's prescriptions. A liberal fluid intake is encouraged to replace the cerebrospinal fluid removed during the procedure, unless contraindicated by the client's condition. The nurse checks the puncture site for redness and drainage and assesses the client's ability to void and move the extremities.

An 84-year-old client in an acute state of disorientation is brought to the hospital emergency department by his or her daughter. The daughter states that the client was "clear as a bell this morning." The nurse determines from this piece of information that which is an unlikely cause of the disorientation? 1.Hypoglycemia 2.Alzheimer's disease 3.Medication dosage error 4.Impaired circulation to the brain

2 Rationale: Alzheimer's disease is a chronic disease with progression of memory deficits over time. The situation presented in the question represents an acute problem. Evaluation is necessary to determine whether hypoglycemia, medication use, or impaired cerebral circulation has had a role in causing the client's current symptoms.

The nurse is assessing a client's gait, which is characterized by unsteadiness and staggering steps. The nurse determines the presence of which type of gait? 1.Spastic 2.Ataxic 3.Festinating 4. Dystrophic or broad-based

2 Rationale: An ataxic gait is characterized by unsteadiness and staggering. A spastic gait is characterized by stiff, short steps with the legs held together, hip and knees flexed, and toes that catch and drag. A festinating gait is best described as walking on the toes with an accelerating pace. A dystrophic or broad-based gait is seen as waddling, with the weight shifting from side to side and the legs far apart.

The home care nurse is visiting a client with a diagnosis of Parkinson's disease. The client is taking benztropine mesylate (Cogentin) orally daily. The nurse provides information to the spouse regarding the side effects of this medication and should tell the spouse to report which side effect if it occurs? 1. Shuffling gait 2. Inability to urinate 3. Decreased appetite 4. Irregular bowel movements

2 Rationale: Benztropine mesylate is an anticholinergic, which causes urinary retention as a side effect. The nurse would instruct the client or spouse about the need to monitor for difficulty with urinating, a distended abdomen, infrequent voiding in small amounts, and overflow incontinence. Options 1, 3, and 4 are unrelated to the use of this medication.

A client has a high level of carbon dioxide (CO2) in the bloodstream, as measured by arterial blood gases. A nurse reviewing the client's record plans care, knowing that a high CO2 level will have which effect on circulation to the brain? 1.It will cause arteriovenous shunting. 2.It will cause vasodilation of blood vessels in the brain. 3. It will cause blood vessels in the circle of Willis to collapse. 4. It will cause hyperresponsiveness of blood vessels in the brain.

2 Rationale: CO2 is one of the metabolic end products that can alter the tone of the blood vessels in the brain. High CO2 levels cause vasodilation, which may cause headache, whereas low CO2 levels cause vasoconstriction, which may cause lightheadedness. The statements included in the other options are incorrect effects.

A client with recent-onset Bell's palsy is upset and crying about the change in facial appearance. The nurse plans to support the client emotionally by making which statement to the client? 1. This is caused by a small tumor, which can be removed easily. 2.This is not a brain attack (stroke), and many clients recover in 3 to 5 weeks. 3. This is a temporary problem, with treatment similar to that for migraine headaches. 4. This is similar to a brain attack (stroke), but all symptoms will reverse without treatment.

2 Rationale: Clients with Bell's palsy should be reassured that they have not experienced a brain attack (stroke) and that symptoms often disappear spontaneously in 3 to 5 weeks. The client is given supportive treatment for symptoms. Bell's palsy usually is not caused by a tumor, and the treatment is not similar to that for migraine headaches.

The nurse in the health care clinic is providing medication instructions to a client with a seizure disorder who will be taking divalproex sodium (Depakote). The nurse should instruct the client about the importance of returning to the clinic for monitoring of which laboratory study? 1.Electrolyte panel 2. Liver function studies 3.Renal function studies 4. Blood glucose level determination

2 Rationale: Divalproex sodium, an anticonvulsant, can cause fatal hepatotoxicity. The nurse should instruct the client about the importance of monitoring the results of liver function studies and ammonia level determinations. Options 1, 3, and 4 are not studies that are required with the use of this medication

The nurse is assessing the function of cranial nerve XII in a client who sustained a stroke. To assess function of this nerve, which action should the nurse ask the client to perform? 1.Extend the arms. 2.Extend the tongue. 3.Turn the head toward the nurse's arm. 4.Focus the eyes on the object held by the nurse.

2 Rationale: Impairment of cranial nerve XII can occur with a stroke. To assess the function of cranial nerve XII (the hypoglossal nerve), the nurse would assess the client's ability to extend the tongue. Options 1, 3, and 4 do not test the function of cranial nerve XII.

The nurse assigned to the care of an unconscious client is making initial daily rounds. On entering the client's room, the nurse observes that the client is lying supine in bed, with the head of the bed elevated approximately 5 degrees. The nasogastric tube feeding is running at 70 mL/hr, as prescribed. The nurse assesses the client and auscultates adventitious breath sounds. Which judgment should the nurse formulate for the client? 1.Impaired nutritional intake 2.Increased risk for aspiration 3.Increased likelihood for injury 4. Susceptibility to fluid volume deficit

2 Rationale: Increased risk for aspiration is a condition in which an individual is at risk for entry of gastrointestinal (GI) secretions, oropharyngeal secretions, or solids or fluids into tracheobronchial passages. Conditions that place the client at risk for aspiration include reduced level of consciousness, depressed cough and gag reflexes, and feeding via a GI tube. There is no information in the question indicating that option 1, 3, or 4 is a concern.

The nurse is assessing the motor function of an unconscious client. The nurse should plan to use which technique to test the client's peripheral response to pain? 1.Sternal rub 2.Nail bed pressure 3.Pressure on the orbital rim 4.Squeezing of the sternocleidomastoid muscle

2 Rationale: Motor testing in the unconscious client can be done only by testing response to painful stimuli. Nail bed pressure tests a basic peripheral response. Cerebral responses to pain are tested using a sternal rub, placing upward pressure on the orbital rim, or squeezing the clavicle or sternocleidomastoid muscle.

The nurse is caring for a client who begins to experience seizure activity while in bed. Which action by the nurse is contraindicated? 1.Loosening restrictive clothing 2.Restraining the client's limbs 3.Removing the pillow and raising padded side rails 4. Positioning the client to the side, if possible, with the head flexed forward

2 Rationale: Nursing actions during a seizure include providing for privacy, loosening restrictive clothing, removing the pillow and raising padded side rails in the bed, and placing the client on one side with the head flexed forward, if possible, to allow the tongue to fall forward and facilitate drainage. The limbs are never restrained because the strong muscle contractions could cause the client harm. If the client is not in bed when seizure activity begins, the nurse lowers the client to the floor, if possible, protects the head from injury, and moves furniture that may injure the client.

A nurse is assessing a client's muscle strength and notes that when asked, the client cannot maintain his or her hands in a supinated position with the arms extended and eyes closed. How should the nurse correctly document this finding on the medical record? 1. Client is demonstrating ataxia. 2. Client is exhibiting pronator drift. 3. Client appears to have nystagmus. 4. Client examination reveals hyperreflexia.

2 Rationale: Pronator drift occurs when a client cannot maintain his or her hands in a supinated position with the arms extended and eyes closed. This assessment may be done to detect small changes in muscle strength that might not otherwise be noted. Ataxia is a disturbance in gait. Hyperreflexia is an excessive reflex action. Nystagmus is characterized by fine, involuntary eye movements. It can occur with neurological disease or as a side effect of selected medications.

The nurse is performing an assessment on a client with Guillain-Barré syndrome. The nurse determines that which finding would be of most concern? 1.Difficulty articulating words 2.Lung vital capacity of 10 mL/kg 3.Paralysis progressing from the toes to the waist 4.A blood pressure (BP) decrease from 110/78 to 102/70 mm Hg

2 Rationale: Respiratory compromise is a major concern in clients with Guillain-Barré syndrome. Clients often are intubated and mechanically ventilated when the vital capacity is less than 15 mL/kg. Options 1 and 3 are expected, depending on the degree of paralysis that occurs. Although orthostatic hypotension is a problem with these clients, the BP drop in option 4 is less than 10 mm Hg and is not significant.

The clinic nurse is reviewing the record of a client scheduled to be seen in the clinic. The nurse notes that the client is taking selegiline hydrochloride (Eldepryl). The nurse suspects that the client has which disorder? 1. Diabetes mellitus 2. Parkinson's disease 3. Alzheimer's disease 4. Coronary artery disease

2 Rationale: Selegiline hydrochloride is an antiparkinsonian medication. The medication increases dopaminergic action, assisting in the reduction of tremor, akinesia, and the rigidity of parkinsonism. This medication is not used to treat diabetes mellitus, Alzheimer's disease, or coronary artery disease.

A client with a neurological deficit is able, with eyes closed, to identify a set of keys placed in his or her hands. A nurse observing the client interprets this to mean that which area of the brain is intact? 1. Frontal lobe 2. Parietal lobe 3. Temporal lobe 4. Occipital lobe

2 Rationale: The ability to distinguish an object by touch is called stereognosis, which is a function of the right parietal area. The parietal lobe of the brain is responsible for spatial orientation and awareness of sizes and shapes. The left parietal area is responsible for mathematics and right-left orientation. The other lobes of the brain are not responsible for this function.

A client with myasthenia gravis is having difficulty with airway clearance and difficulty with maintaining an effective breathing pattern. The nurse should keep which items available at the client's bedside? 1.Oxygen and metered-dose inhaler 2.Ambu bag and suction equipment 3.Pulse oximeter and cardiac monitor 4.Incentive spirometer and cough pillow

2 Rationale: The client with myasthenia gravis may experience episodes of respiratory distress if excessively fatigued or with development of myasthenic or cholinergic crisis. For this reason, an Ambu bag, intubation tray, and suction equipment should be available at the bedside.

The nurse is documenting nursing observations in the record of a client who experienced a tonic-clonic seizure. Which clinical manifestation did the nurse most likely note in the clonic phase of the seizure? 1.Body stiffening 2.Spasms of the entire body 3.Sudden loss of consciousness 4.Brief flexion of the extremities

2 Rationale: The clonic phase of a seizure is characterized by alternating spasms and momentary muscular relaxation of the entire body, accompanied by strenuous hyperventilation. The face is contorted and the eyes roll. Excessive salivation results in frothing from the mouth. The tongue may be bitten, the client sweats profusely, and the pulse is rapid. The clonic jerking subsides by slowing in frequency and losing strength of contractions over a period of 30 seconds. Options 1, 3, and 4 identify the tonic phase of a seizure.

A nurse notes that a client who has suffered a brain injury has an adequate heart rate, blood pressure, fluid balance, and body temperature. The nurse concludes that which area of the client's brain is functioning adequately? 1. Thalamus 2. Hypothalamus 3. Limbic system 4. Reticular activating system

2 Rationale: The hypothalamus is responsible for autonomic nervous system functions, such as heart rate, blood pressure, temperature, and fluid and electrolyte balance (among others). The thalamus acts as a relay station for sensory and motor information. The limbic system is responsible for emotions. The reticular activating system is responsible for the sleep-wake cycle.

The nurse is reviewing the record for a client seen in the health care clinic and notes that the health care provider has documented a diagnosis of amyotrophic lateral sclerosis (ALS). Which initial clinical manifestation of this disorder should the nurse expect to see documented in the record? 1. Muscle wasting 2. Mild clumsiness 3. Altered mentation 4. Diminished gag reflex

2 Rationale: The initial symptom of ALS is a mild clumsiness, usually noted in the distal portion of one extremity. The client may complain of tripping and drag one leg when the lower extremities are involved. Mentation and intellectual function usually are normal. Diminished gag reflex and muscle wasting are not initial clinical manifestations.

A client has a neurological deficit involving the limbic system. Which assessment finding is specific to this type of deficit? 1.Is disoriented to person, place, and time 2.Affect is flat, with periods of emotional lability 3.Cannot recall what was eaten for breakfast today 4. Demonstrates inability to add and subtract; does not know who is the president of the United States

2 Rationale: The limbic system is responsible for feelings (affect) and emotions. Calculation ability and knowledge of current events relate to function of the frontal lobe. The cerebral hemispheres, with specific regional functions, control orientation. Recall of recent events is controlled by the hippocampus.

A client is admitted with an exacerbation of multiple sclerosis. The nurse is assessing the client for possible precipitating risk factors. Which factor, if reported by the client, should the nurse identify as being unrelated to the exacerbation? 1.Annual influenza vaccination 2.Ingestion of increased fruits and vegetables 3.An established routine of walking 2 miles each evening 4.A recent period of extreme outside ambient temperatures

2 Rationale: The onset or exacerbation of multiple sclerosis can be preceded by a number of different factors, including physical stress (e.g., vaccination, excessive exercise), emotional stress, fatigue, infection, physical injury, pregnancy, extremes in environmental temperature, and high humidity. No methods of primary prevention are known. Intake of fruits and vegetables is an unrelated item.

A client with Parkinson's disease is at risk for falls because of an abnormal gait. The nurse assesses the client, expecting to observe which type of gait? 1. Unsteady and staggering 2. Shuffling and propulsive 3. Broad-based and waddling 4.Accelerating with walking on the toes

2 Rationale: The parkinsonian gait is characterized by short, accelerating, shuffling steps. The client leans forward with the head, hips, and knees flexed and has difficulty starting and stopping. An ataxic gait is unsteady and staggering. A dystrophic gait is broad-based and waddling. A festinating gait is accelerating with walking on the toes.

A client has sustained damage to Wernicke's area in the temporal lobe from a stroke (brain attack). The nurse anticipates that the client will have difficulty with which function? 1.Articulating words 2. Understanding language 3. Moving one side of the body 4. Recalling events in the remote past

2 Rationale: Wernicke's area consists of a small group of cells in the temporal lobe whose function is the understanding of language. Damage to Broca's area is responsible for aphasia. The motor cortex in the precentral gyrus controls voluntary motor activity. The hippocampus is responsible for the storage of memory.

The nurse is reviewing the record of a child with increased intracranial pressure and notes that the child has exhibited signs of decerebrate posturing. On assessment of the child, the nurse expects to note which characteristic of this type of posturing? 1.Flaccid paralysis of all extremities 2.Adduction of the arms at the shoulders 3.Rigid extension and pronation of the arms and legs 4.Abnormal flexion of the upper extremities and extension and adduction of the lower extremities

3 Rationale: Decerebrate (extension) posturing is characterized by the rigid extension and pronation of the arms and legs. Option 1 is incorrect. Options 2 and 4 describe decorticate (flexion) posturing.

The nurse has given suggestions to a client with trigeminal neuralgia about strategies to minimize episodes of pain. The nurse determines that the client needs further education if the client makes which statement? 1."I will wash my face with cotton pads." 2."I'll have to start chewing on my unaffected side." 3."I'll try to eat my food either very warm or very cold." 4."I should rinse my mouth if toothbrushing is painful."

3 Rationale: Facial pain can be minimized by using cotton pads to wash the face and using room temperature water. The client should chew on the unaffected side of the mouth, eat a soft diet, and take in foods and beverages at room temperature. If toothbrushing triggers pain, an oral rinse after meals may be helpful instead.

The nurse is preparing for the admission to the unit of a client with a diagnosis of seizures and is preparing to institute full seizure precautions. Which item is contraindicated for use if a seizure occurs? 1.Oxygen source 2.Suction machine 3.Padded tongue blade 4.Padding for the side rails

3 Rationale: Full seizure precautions include bed rest with padded side rails in a raised position, a suction machine at the bedside, having diazepam (Valium) or lorazepam (Ativan) available, and providing an oxygen source. Objects such as tongue blades are contraindicated and should never be placed in the client's mouth during a seizure.

The nurse is monitoring a client who has returned to the nursing unit after a myelogram. Which client complaint would indicate the need to notify the health care provider (HCP)? 1.Backache 2.Headache 3.Neck stiffness 4. Feelings of fatigue

3 Rationale: Headache is relatively common after the procedure, but neck stiffness, especially on flexion, and pain should be reported because they signal meningeal irritation. The client also is monitored for evidence of allergic reactions to the dye such as confusion, dizziness, tremors, and hallucinations. Feelings of fatigue may be normal, and back discomfort may be owing to the positions required for the procedure.

A client is being hyperventilated by a mechanical ventilator to decrease the client's intracranial pressure (ICP). On monitoring arterial blood gas results, the nurse should expect values that are within which ranges? 1.Pao2 60 to 100 mm Hg, Paco2 25 to 30 mm Hg 2.Pao2 60 to 100 mm Hg, Paco2 30 to 35 mm Hg 3.Pao2 80 to 100 mm Hg, Paco2 25 to 30 mm Hg 4. Pao2 80 to 100 mm Hg, Paco2 35 to 40 mm Hg

3 Rationale: Hyperventilation with a Paco2 of 25 to 30 mm Hg causes cerebral vasoconstriction, which decreases intracranial blood volume and ICP. The Pao2 is not allowed to fall below 80 mm Hg, to prevent cerebral vasodilation from hypoxemia. Therefore, the remaining options are incorrect.

A lumbar puncture is performed on a child suspected to have bacterial meningitis, and cerebrospinal fluid (CSF) is obtained for analysis. The nurse reviews the results of the CSF analysis and determines that which results would verify the diagnosis? 1.Clear CSF, decreased pressure, and elevated protein level 2.Clear CSF, elevated protein, and decreased glucose levels 3.Cloudy CSF, elevated protein, and decreased glucose levels 4.Cloudy CSF, decreased protein, and decreased glucose levels

3 Rationale: Meningitis is an infectious process of the central nervous system caused by bacteria and viruses; it may be acquired as a primary disease or as a result of complications of neurosurgery, trauma, infection of the sinus or ears, or systemic infections. Meningitis is diagnosed by testing cerebrospinal fluid obtained by lumbar puncture. In the case of bacterial meningitis, findings usually include an elevated pressure; turbid or cloudy cerebrospinal fluid; and elevated leukocyte, elevated protein, and decreased glucose levels

The nurse has instructed a client with myasthenia gravis about strategies for self-management at home. The nurse determines a need for more information if the client makes which statement? 1."Here's the Medic-Alert bracelet I obtained." 2."I should take my medications an hour before mealtime." 3."Going to the beach will be a nice, relaxing form of activity." 4."I've made arrangements to get a portable resuscitation bag and home suction equipment."

3 Rationale: Most ongoing treatment for myasthenia gravis is done in outpatient settings, and the client must be aware of the lifestyle changes needed to maintain independence. The client should carry medical identification about the presence of the condition. Taking medications an hour before mealtime gives greater muscle strength for chewing and is indicated. The client should have portable suction equipment and a portable resuscitation bag available in case of respiratory distress. The client should avoid situations and other factors, including stress, infection, heat, surgery, and alcohol, that could worsen the symptoms.

A client with multiple sclerosis is experiencing muscle weakness, spasticity, and an ataxic gait. On the basis of this information, the nurse should include which client problem in the plan of care? 1.Inability to care for self 2.Interruption in skin integrity 3.Interruption in physical mobility 4.Inability to perform daily activities

3 Rationale: Multiple sclerosis is a chronic, nonprogressive, noncontagious degenerative disease of the central nervous system characterized by demyelinization of the neurons. Interruption in physical mobility is most appropriate for the client with multiple sclerosis experiencing muscle weakness, spasticity, and ataxic gait. Options 1, 2, and 4 are not related to the data in the question.

A client with a history of myasthenic gravis presents at a clinic with bilateral ptosis and is drooling, and myasthenia crisis is suspected. The nurse assesses the client for which precipitating factor? 1. Getting too little exercise 2. Taking excess medication 3. Omitting doses of medication 4. Increasing intake of fatty foods

3 Rationale: Myasthenic crisis often is caused by undermedication and responds to the administration of cholinergic medications. Cholinergic crisis (the opposite problem) is caused by excess medication and responds to withholding of medications. Too little exercise and excessive fatty food intake are incorrect. Overexertion and overeating possibly could trigger myasthenic crisis.

The home health nurse is visiting a client with a diagnosis of multiple sclerosis. The client has been taking oxybutynin (Ditropan XL). The nurse evaluates the effectiveness of the medication by asking the client which assessment question? 1."Are you consistently fatigued?" 2. "Are you having muscle spasms?" 3. "Are you getting up at night to urinate?" 4. "Are you having normal bowel movements?"

3 Rationale: Oxybutynin is an antispasmodic used to relieve symptoms of urinary urgency, frequency, nocturia, and incontinence in clients with uninhibited or reflex neurogenic bladder. Expected effects include improved urinary control and decreased urinary frequency, incontinence, and nocturia. Options 1, 2, and 4 are unrelated to the use of this medication.

The nurse is assessing a client with a neurological deficit involving the hippocampus. Which finding is indicative of this deficit? 1. Disoriented to client, place, and time 2. Affect flat, with periods of emotional lability 3. Cannot recall what was eaten for breakfast today 4. Unable to add and subtract; does not know who is president

3 Rationale: Recall of recent events and the storage of memories are controlled by the hippocampus, which is a limbic system structure. The cerebral hemispheres, with specific regional functions, control orientation. The limbic system, overall, is responsible for feelings, affect, and emotions. Calculation ability and knowledge of current events are under the control of the frontal lobes of the cerebrum.

The nurse is evaluating the respiratory outcomes for a client with Guillain-Barré syndrome. The nurse determines that which is the least optimal outcome for the client? 1. Spontaneous breathing 2. Oxygen saturation of 98% 3. Adventitious breath sounds 4. Vital capacity within normal range

3 Rationale: Satisfactory respiratory outcomes for a client with Guillain-Barré syndrome include clear breath sounds on auscultation, spontaneous breathing, normal vital capacity, normal arterial blood gas levels, and normal pulse oximetry. Adventitious breath sounds are an abnormal finding.

A client had a seizure 1 hour ago. Family members were present during the episode and reported that the client's jaw was moving as though grinding food. In helping to determine the origin of this seizure, what should the nurse include in the client's assessment? 1.Presence of diaphoresis 2.Loss of consciousness 3.History of prior trauma 4. Rotating eye movements

3 Rationale: Seizures that originate with specific motor phenomena are considered focal and are indicative of a focal structural lesion in the brain, often caused by trauma, infection, or drug consumption. Options 1, 2, and 4 address signs, rather than an origin of the seizure.

A client with a neurological problem is experiencing hyperthermia. Which measure would be least appropriate for the nurse to use in trying to lower the client's body temperature? 1.Giving tepid sponge baths 2.Applying a hypothermia blanket 3.Placing ice packs in the axilla and groin areas 4. Administering acetaminophen (Tylenol) per protocol

3 Rationale: Standard measures to lower body temperature include removing bed covers, providing cool sponge baths, using an electric fan in the room, administering acetaminophen, and placing a hypothermia blanket under the client. Ice packs are not used because they could cause shivering, which increases cellular oxygen demands, with the potential for increased intracranial pressure.

A client is somewhat nervous about undergoing magnetic resonance imaging (MRI). Which statement by the nurse would provide the most reassurance to the client about the procedure? 1."The MRI machine is a long, narrow, hollow tube and may make you feel somewhat claustrophobic." 2."You will be able to eat before the procedure unless you get nauseated easily. If so, you should eat lightly." 3."Even though you are alone in the scanner, you will be in voice communication with the technologist at all times during the procedure." 4. "It is necessary to remove any metal or metal-containing objects before having the MRI done to avoid the metal being drawn into the magnetic field."

3 Rationale: The MRI scanner is a hollow tube that gives some clients a feeling of claustrophobia. Metal objects must be removed before the procedure so that they are not drawn into the magnetic field. The client may eat and may take all prescribed medications before the procedure. If a contrast medium is used, the client may wish to eat lightly if he or she has a tendency to become nauseated easily. The client lies supine on a padded table that moves into the imager. The client must lie still during the procedure. The imager makes tapping noises during the scanning. The client is alone in the imager, but the nurse can reassure the client that the technologist will be in voice communication with the client at all times during the procedure.

A client with Guillain-Barré syndrome has ascending paralysis and is intubated and receiving mechanical ventilation. Which strategy should the nurse incorporate in the plan of care to help the client cope with this illness? 1.Giving client full control over care decisions and restricting visitors 2.Providing positive feedback and encouraging active range of motion 3.Providing information, giving positive feedback, and encouraging relaxation 4. Providing intravenously administered sedatives, reducing distractions, and limiting visitors

3 Rationale: The client with Guillain-Barré syndrome experiences fear and anxiety from the ascending paralysis and sudden onset of the disorder. The nurse can alleviate these fears by providing accurate information about the client's condition, giving expert care and positive feedback to the client, and encouraging relaxation and distraction. The family can become involved with selected care activities and provide diversion for the client as well.

The nurse has given instructions to a client with Parkinson's disease about maintaining mobility. Which action demonstrates that the client understands the directions? 1.Sits in soft, deep chairs to promote comfort. 2.Exercises in the evening to combat fatigue. 3.Rocks back and forth to start movement with bradykinesia. 4. Buys clothes with many buttons to maintain finger dexterity.

3 Rationale: The client with Parkinson's disease should exercise in the morning when energy levels are highest. The client should avoid sitting in soft deep chairs because they are difficult to get up from. The client can rock back and forth to initiate movement. The client should buy clothes with Velcro fasteners and slide-locking buckles to support the ability to dress self.

A client has suffered a head injury affecting the occipital lobe of the brain. The nurse anticipates that the client may experience difficulty with which sense? 1. Smell 2. Taste 3. Vision 4. Hearing

3 Rationale: The occipital lobe is responsible for reception of vision and contains visual association areas. This area of the brain helps the individual to visually recognize and understand the surroundings. The other senses listed are not a function of the occipital lobe.

A nurse is preparing to administer a prescribed antibiotic to a client with bacterial meningitis. The nurse understands that the selection of an antibiotic to treat meningitis is based on which fact? 1. It has a long half-life. 2. It acts within minutes to hours. 3. It can be easily excreted in the urine. 4. It is able to cross the blood-brain barrier.

4 Rationale: A primary consideration regarding medications to treat bacterial meningitis is the ability of the medication to cross the blood-brain barrier. If the medication cannot cross, it will not be effective. The duration, onset, and excretion of the medication(options 1, 2, and 3) are also of general concern but apply to all medications and not specifically to those that are used to treat meningitis.

The nurse develops a plan of care for a child at risk for tonic-clonic seizures. In the plan of care, the nurse identifies seizure precautions and documents that which item(s) need to be placed at the child's bedside? 1.Emergency cart 2.Tracheotomy set 3.Padded tongue blade 4.Suctioning equipment and oxygen

4 Rationale: A seizure results from the excessive and unorganized neuronal discharges in the brain that activate associated motor and sensory organs. A type of generalized seizure is a tonic-clonic seizure. This type of seizure causes rigidity of all body muscles, followed by intense jerking movements. Because increased oral secretions and apnea can occur during and after the seizure, oxygen and suctioning equipment are placed at the bedside. A tracheotomy is not performed during a seizure. No object, including a padded tongue blade, is placed into the child's mouth during a seizure. An emergency cart would not be left at the bedside, but would be available in the treatment room or nearby on the nursing unit.

The nurse is assisting with caloric testing of the oculovestibular reflex in an unconscious client. Cold water is injected into the left auditory canal. The client exhibits eye conjugate movements toward the left, followed by eye movement back to midline. The nurse understands that this finding indicates which situation? 1.Brain death 2.A cerebral lesion 3.A temporal lesion 4.An intact brainstem

4 Rationale: Caloric testing provides information about differentiating between cerebellar and brainstem lesions. After determining patency of the ear canal, cold or warm water is injected into the auditory canal. A normal response that indicates intact function of cranial nerves III, VI, and VIII is conjugate eye movements toward the side being irrigated, followed by eye movement back to midline. Absent or dysconjugate eye movements indicate brainstem damage.

The parents of a child recently diagnosed with cerebral palsy ask the nurse about the disorder. The nurse bases the response on the understanding that cerebral palsy is which type of condition? 1. An infectious disease of the central nervous system 2. An inflammation of the brain as a result of a viral illness 3. A congenital condition that results in moderate to severe retardation 4. A chronic disability characterized by impaired muscle movement and posture

4 Rationale: Cerebral palsy is a chronic disability characterized by impaired movement and posture resulting from an abnormality in the extrapyramidal or pyramidal motor system. Meningitis is an infectious process of the central nervous system. Encephalitis is an inflammation of the brain that occurs as a result of viral illness or central nervous system infection. Down syndrome is an example of a congenital condition that results in moderate to severe retardation.

The nurse is planning care for a client who displays confusion secondary to a neurological problem. Which approach by the nurse would be least helpful in assisting this client? 1.Providing sensory cues 2.Giving simple, clear directions 3.Providing a stable environment 4. Encouraging multiple visitors at one time

4 Rationale: Clients with cognitive impairment from neurological dysfunction respond best to a stable environment that is limited in amount and type of sensory input. The nurse can provide sensory cues and give clear, simple directions in a positive manner. Confusion can be minimized by reducing environmental stimuli (such as television or multiple visitors) and by keeping familiar personal articles (such as family pictures) at the bedside.

The nurse is teaching a client with myasthenia gravis about the prevention of myasthenic and cholinergic crises. Which client activity suggests that teaching is most effective? 1.Eating large, well-balanced meals 2.Doing muscle-strengthening exercises 3.Doing all chores early in the day while less fatigued 4. Taking medications on time to maintain therapeutic blood levels

4 Rationale: Clients with myasthenia gravis are taught to space out activities over the day to conserve energy and restore muscle strength. Taking medications correctly to maintain blood levels that are not too low or too high is important. Muscle-strengthening exercises are not helpful and can fatigue the client. Overeating is a cause of exacerbation of symptoms, as is exposure to heat, crowds, erratic sleep habits, and emotional stress.

The client has an impairment of cranial nerve II. Specific to this impairment, what should the nurse should plan to do to ensure client safety? 1. Speak loudly to the client. 2.Test the temperature of the shower water. 3.Check the temperature of the food on the dietary tray. 4. Provide a clear path for ambulation without obstacles.

4 Rationale: Cranial nerve II is the optic nerve, which governs vision. The nurse can provide safety for the visually impaired client by clearing the path of obstacles when ambulating. Speaking loudly may help overcome a deficit of cranial nerve VIII (vestibulocochlear). Testing the shower water temperature would be useful if there were an impairment of peripheral nerves. Cranial nerve VII (facial) and IX (glossopharyngeal) control taste from the anterior two thirds and posterior third of the tongue, respectively.

The nurse is providing diet instructions to a client with Ménière's disease who is being discharged from the hospital after admission for an acute attack. Which statement, if made by the client, indicates an understanding of the dietary measures to take to help prevent further attacks? 1."I need to restrict my carbohydrate intake." 2."I need to drink at least 3 L of fluid per day." 3."I need to maintain a low-fat and low-cholesterol diet." 4. "I need to be sure to consume foods that are low in sodium."

4 Rationale: Dietary changes, such as salt and fluid restrictions, that reduce the amount of endolymphatic fluid are sometimes prescribed for the client with Ménière's disease. The client should be instructed to consume a low-sodium diet and restrict fluids as prescribed. Although helpful to treat other disorders, low-fat, low-carbohydrate, and low-cholesterol diets are not specifically prescribed for the client with Ménière's disease.

The client is admitted to the hospital with a diagnosis of Guillain-Barré syndrome. Which past medical history finding makes the client most at risk for this disease? 1.Meningitis or encephalitis during the last 5 years 2.Seizures or trauma to the brain within the last year 3. Back injury or trauma to the spinal cord during the last 2 years 4.Respiratory or gastrointestinal infection during the previous month

4 Rationale: Guillain-Barré syndrome is a clinical syndrome of unknown origin that involves cranial and peripheral nerves. Many clients report a history of respiratory or gastrointestinal infection in the 1 to 4 weeks before the onset of neurological deficits. On occasion, the syndrome can be triggered by vaccination or surgery.

The nurse is caring for an unconscious client who is experiencing persistent hyperthermia with no signs of infection. The nurse interprets that the hyperthermia may be related to damage to the client's thermoregulatory center in which structure? 1.Cerebrum 2.Cerebellum 3.Hippocampus 4.Hypothalamus

4 Rationale: Hypothalamic damage causes persistent hyperthermia, which also may be called central fever. It is characterized by a persistent high fever with no diurnal variation. Another characteristic feature is absence of sweating. Hyperthermia would not result from damage to the cerebrum, cerebellum, or hippocampus.

The nurse in the neurological unit is caring for a client with a supratentorial lesion. The nurse assesses which measurement as the most critical index of central nervous system (CNS) dysfunction? 1.Temperature 2.Blood pressure 3.Ability to speak 4.Level of consciousness

4 Rationale: Level of consciousness is the most critical index of CNS dysfunction. Changes in level of consciousness can indicate clinical improvement or deterioration. Although blood pressure, temperature, and ability to speak may be components of the assessment, the client's level of consciousness is the most critical index of CNS dysfunction.

The nurse notes documentation that a child with meningitis is exhibiting a positive Kernig's sign. Which observation is characteristic of this sign? 1. The child complains of muscle and joint pain. 2. Petechial and purpuric rashes are noted on the child's trunk. 3. Neck flexion causes adduction and flexion movements of the lower extremities. 4. The child is not able to extend the leg when the thigh is flexed anteriorly at the hip.

4 Rationale: Meningitis is an infectious process of the central nervous system caused by bacteria and viruses. The inability to extend the leg when the thigh is flexed anteriorly at the hip is a positive Kernig's sign, noted in meningitis. Muscle and joint pain is characteristic of meningococcal infection and H. influenzae infection. A petechial or purpuric rash is characteristic of meningococcal infection. A positive Brudzinski's sign is noted when neck flexion causes adduction and flexion movements of the lower extremities in children and adolescents. This is also a characteristic of meningitis.

A nurse is caring for a client with an intracranial pressure (ICP) monitoring device. The nurse should become most concerned if the ICP readings drifted to and stayed in the vicinity of which finding? 1.5 mm Hg 2.8 mm Hg 3.14 mm Hg 4. 22 mm Hg

4 Rationale: Normal ICP readings range from 5 to 15 mm Hg pressure. Pressures greater than 20 mm Hg are considered to represent increased ICP, which seriously impairs cerebral perfusion.

The nurse is planning care for the client with a neurogenic bladder caused by multiple sclerosis. The nurse plans for fluid administration of at least 2000 mL/day. Which plan would be most helpful to this client? 1.400 to 500 mL with each meal and 500 to 600 mL in the evening before bedtime 2.400 to 500 mL with each meal and additional fluids in the morning but not after midday 3.400 to 500 mL with each meal, with all extra fluid concentrated in the afternoon and evening 4.400 to 500 mL with each meal and 200 to 250 mL at midmorning, midafternoon, and late afternoon

4 Rationale: Spacing fluid intake over the day helps the client with a neurogenic bladder to establish regular times for successful voiding. Omitting intake after the evening meal minimizes incontinence or the need to empty the bladder during the night.

The home care nurse is preparing to visit a client with a diagnosis of trigeminal neuralgia (tic douloureux). When performing the assessment, the nurse should plan to ask the client which question to elicit the most specific information regarding this disorder? 1."Do you have any visual problems?" 2. "Are you having any problems hearing?" 3. "Do you have any tingling in the face region?" 4. "Is the pain experienced a stabbing type of pain?"

4 Rationale: Trigeminal neuralgia is characterized by spasms of pain that start suddenly and last for seconds to minutes. The pain often is characterized as stabbing or as similar to an electric shock. It is accompanied by spasms of facial muscles that cause twitching of parts of the face or mouth, or closure of the eye. Options 1, 2, and 3 do not elicit data specifically related to this disorder.

The nurse is performing an assessment on a client with a diagnosis of Bell's palsy. The nurse should expect to observe which finding in the client? 1.Facial drooping 2.Periorbital edema 3. Ptosis of the eyelid 4. Twitching on the affected side of the face

1 Rationale: Bell's palsy is a one-sided facial paralysis caused by the compression of the facial nerve (cranial nerve VII). Assessment findings include facial droop from paralysis of the facial muscles; increased lacrimation; painful sensations in the eye, face, or behind the ear; and speech or chewing difficulty. Options 2, 3, and 4 are not associated findings in Bell's palsy.

The nurse has determined that a client with a neurological disorder also has difficulty breathing. Which activities would be appropriate components of the care plan for this client? Select all that apply. 1.Keep suction equipment at the bedside. 2.Elevate the head of the bed 30 degrees. 3.Keep the client lying in a supine position. 4.Keep the head and neck in good alignment. 5. Administer prescribed respiratory treatments as needed.

1,2,4,5 Rationale: The nurse maintains a patent airway for the client with difficulty breathing by keeping the head and neck in good alignment and elevating the head of bed 30 degrees unless contraindicated. Suction equipment is kept at the bedside if secretions need to be cleared. The client should be kept in a side-lying position whenever possible to minimize the risk of aspiration.

A client is diagnosed with Bell's palsy. The nurse assessing the client expects to note which symptom? 1.A symmetrical smile 2.Difficulty closing the eyelid on the affected side 3.Narrowing of the palpebral fissure on the affected side 4.Paroxysms of excruciating pain in the lips and cheek on the affected side

2 Rationale: The facial drooping associated with Bell's palsy makes it difficult for the client to close the eyelid on the affected side. A widening of the palpebral fissure (the opening between the eyelids) and an asymmetrical smile are seen with Bell's palsy. Paroxysms of excruciating pain are characteristic of trigeminal neuralgia.

A client with a neurological impairment experiences urinary incontinence. Which nursing action would be most helpful in assisting the client to adapt to this alteration? 1.Using adult diapers 2.Inserting a Foley catheter 3.Establishing a toileting schedule 4. Padding the bed with an absorbent cotton pad

3 Rationale: A bladder retraining program, such as use of a toileting schedule, may be helpful to clients experiencing urinary incontinence. A Foley catheter should be used only when necessary because of the associated risk of infection. Use of diapers or pads is the least acceptable alternative because of the risk of skin breakdown.

The nurse is preparing to care for a client after a lumbar puncture. The nurse should plan to place the client in which best position immediately after the procedure? 1.Prone in semi-Fowler's position 2.Supine in semi-Fowler's position 3.Prone with a small pillow under the abdomen 4. Lateral with the head slightly lower than the rest of the body

3 Rationale: After the procedure, the client assumes a flat position. If the client is able, a prone position with a pillow under the abdomen is the best position. This position helps reduce cerebrospinal fluid leakage and decreases the likelihood of post-lumbar puncture headache. Options 1, 2, and 4 are incorrect.

A client is anxious about an upcoming diagnostic procedure. The client's pupils are dilated, and the respiratory rate, heart rate, and blood pressure are increased from baseline. The nurse plans care, knowing that these changes are the result of which response? 1.Vagal response 2.Peripheral nervous system response 3.Sympathetic nervous system response 4. Parasympathetic nervous system response

3 Rationale: The sympathetic nervous system is responsible for the so-called fight or flight response, which is characterized by dilated pupils, increases in heart rate and cardiac output, and increases in respiratory rate and blood pressure. The sympathetic nervous system response affects some type of change in most systems of the body. The responses stated in the other options do not produce these effects.

A client is experiencing delirium. The nurse concludes that which areas of the nervous system are affected? 1. Temporal lobe and frontal lobe 2. Hippocampus and frontal lobe 3. Limbic system and cerebral hemispheres 4. Reticular activating system and cerebral hemispheres

4 Insomnia, agitation, mania, and delirium are caused by excessive arousal of the reticular activating system in conjunction with the cerebral hemispheres. The temporal lobe, hippocampus, and frontal lobe are responsible for memory. The limbic system is responsible for feelings and affect.

A child is diagnosed with Reye's syndrome. The nurse develops a nursing care plan for the child and should include which intervention in the plan? 1.Assessing hearing loss 2.Monitoring urine output 3.Changing body position every 2 hours 4.Providing a quiet atmosphere with dimmed lighting

4 Rationale: Reye's syndrome is an acute encephalopathy that follows a viral illness and is characterized pathologically by cerebral edema and fatty changes in the liver. A definitive diagnosis is made by liver biopsy. In Reye's syndrome, supportive care is directed toward monitoring and managing cerebral edema. Decreasing stimuli in the environment by providing a quiet environment with dimmed lighting would decrease the stress on the cerebral tissue and neuron responses. Hearing loss and urine output are not affected. Changing the body position every 2 hours would not affect the cerebral edema directly. The child should be positioned with the head elevated to decrease the progression of the cerebral edema and promote drainage of cerebrospinal fluid.

A client is about to undergo a lumbar puncture. The nurse describes to the client that which position will be used during the procedure? 1.Side-lying with a pillow under the hip 2.Prone with a pillow under the abdomen 3.Prone in slight Trendelenburg's position 4. Side-lying with the legs pulled up and the head bent down onto the chest

4Rationale: A client undergoing lumbar puncture is positioned lying on the side, with the legs pulled up to the abdomen and the head bent down onto the chest. This position helps open the spaces between the vertebrae and allows for easier needle insertion by the health care provider. The nurse remains with the client during the procedure to help the client maintain this position. The other options identify incorrect positions for this procedure.

A girl who is playing in the playroom experiences a tonic-clonic seizure. During the seizure, the nurse should take which actions? Select all that apply. 1.Remain calm. 2.Time the seizure. 3.Ease the child to the floor. 4.Loosen restrictive clothing. 5.Keep the child on her back. 6.Place a pillow under the child's head.

12346Rationale: When a child is having a seizure, the nurse should remain calm, time the seizure, ease the child to the floor if the child is standing or seated, keep the child on the side, loosen restrictive clothing, and place a pillow under the child's head.

A thymectomy accomplished via a median sternotomy approach is performed in a client with a diagnosis of myasthenia gravis. The nurse develops a postoperative plan of care for the client that should include which intervention? 1. Monitor the chest tube drainage. 2. Restrict visitors for 24 hours postoperatively. 3. Maintain intravenous infusion of lactated Ringer's solution. 4. Avoid administering pain medication to prevent respiratory depression.

1 Rationale: A thymectomy may be used for management of clients with myasthenia gravis. The procedure is performed through a median sternotomy or a transcervical approach. Postoperatively the client will have a chest tube in the mediastinum. Lactated intravenous solutions usually are avoided because they can increase weakness. Pain medication is administered as needed, but the client is monitored closely for respiratory depression. There is no reason to restrict visitors.

A client has suffered damage to Broca's area of the brain. The nurse providing care for this client anticipates that which area will be affected? 1.Speech 2.Hearing 3.Balance 4.Level of consciousness

1 Rationale: Broca's area in the brain is responsible for the motor aspects of speech, through coordination of the muscular activity of the tongue, mouth, and larynx. The term assigned to damage in this area is aphasia. The items listed in the other options are not the responsibility of Broca's area.

A nurse reviews the plan of care for a child with Reye's syndrome. Which priority intervention should the nurse include in the plan of care? 1.Monitor for signs of increased intracranial pressure. 2.Immediately check the presence of protein in the urine. 3.Reassure the parents hyperglycemia is a common symptom. 4.Teach the parents signs and symptoms of a bacterial infection.

1 Rationale: Intracranial pressure and encephalopathy are major symptoms of Reye's syndrome. Protein is not present in the urine. Reye's syndrome is related to a history of viral infections, and hypoglycemia is a symptom of this disease.

A child is admitted to the hospital with a diagnosis of acute bacterial meningitis. In reviewing the health care provider's prescriptions, which would the nurse question as appropriate for a child with this diagnosis? 1.Administer an oral antibiotic. 2.Maintain strict intake and output. 3.Draw blood for a culture and sensitivity. 4. Place the child on droplet precautions in a private room.

1 Rationale: Medication to treat acute bacterial meningitis is administered intravenously, not orally. A culture and sensitivity is done to determine if the diagnosis is bacterial or viral. Until meningitis is ruled out, the child is placed in isolation on droplet precautions because the disease is spread by airborne means. Strict intake and output should be maintained.

A nurse is monitoring a 7-year-old child who sustained a head injury in a motor vehicle crash for signs of increased intracranial pressure (ICP). The nurse should assess the child frequently for which early sign of increased ICP? 1.Nausea 2.Papilledema 3.Decerebrate posturing 4.Alterations in pupil size

1 Rationale: Nausea is an early sign of increased ICP. Late signs of increased ICP include a significant decrease in level of consciousness, Cushing's triad (increased systolic blood pressure and widened pulse pressure, bradycardia, and irregular respirations), and fixed and dilated pupils. Other late signs include decreased motor response to command, decreased sensory response to painful stimuli, posturing, Cheyne-Stokes respirations, and papilledema.

A nurse is performing an admission assessment on a child with a seizure disorder. The nurse is interviewing the child's parents to determine their adjustment to caring for their child, who has a chronic illness. Which statement, if made by the parents, would indicate a need for further teaching? 1."Our child sleeps in our bedroom at night." 2."We worry about injuries when our child has a seizure." 3."Our child is involved in a swim program with neighbors and friends." 4."Our babysitter just completed cardiopulmonary resuscitation [CPR] training."

1 Rationale: Parents are especially concerned about seizures that might go undetected during the night. The nurse needs to decrease parental overprotection and should suggest the use of a baby monitor at night. Options 3 and 4, involvement in a swim program and knowing CPR identify parental understanding of the disorder. Worrying about injuries when a child has a seizure is a common concern. The parents need to be reminded that as the child grows, they cannot always observe their child, but their knowledge of seizure activity and care is appropriate to minimize complications.

The nurse is planning to institute seizure precautions for a client who is being admitted from the emergency department. Which measures should the nurse include in planning for the client's safety? Select all that apply. 1.Padding the side rails of the bed 2.Placing an airway at the bedside 3.Placing the bed in the high position 4.Putting a padded tongue blade at the head of the bed 5.Placing oxygen and suction equipment at the bedside 6.Having intravenous equipment ready for insertion of an intravenous catheter

1,2,5,6 Rationale: Seizure precautions may vary from agency to agency, but they generally have some common features. Usually, an airway, oxygen, and suctioning equipment are kept available at the bedside. The side rails of the bed are padded, and the bed is kept in the lowest position. The client has an intravenous access in place to have a readily accessible route if anticonvulsant medications must be administered. The use of padded tongue blades is highly controversial, and they should not be kept at the bedside. Forcing a tongue blade into the mouth during a seizure more likely will harm the client who bites down during seizure activity. Risks include blocking the airway from improper placement, chipping the client's teeth, and subsequent risk of aspirating tooth fragments. If the client has an aura before the seizure, it may give the nurse enough time to place an oral airway before seizure activity begins.

The nurse is assessing a client who is experiencing seizure activity. The nurse understands that it is necessary to determine information about which items as part of routine assessment of seizures? Select all that apply. 1.Postictal status 2.Duration of the seizure 3.Changes in pupil size or eye deviation 4.Seizure progression and type of movements 5.What the client ate in the 2 hours preceding seizure activity

1234Rationale: Typically seizure assessment includes the time the seizure began, parts of the body affected, type of movements and progression of the seizure, change in pupil size or eye deviation or nystagmus, client condition during the seizure, and postictal status. Option 5 is not a component of seizure assessment

The nurse is preparing a plan of care for a client with a diagnosis of amyotrophic lateral sclerosis (ALS). On assessment, the nurse notes that the client is severely dysphagic. Which intervention should be included in the care plan for this client? Select all that apply. 1.Provide oral hygiene after each meal. 2.Assess swallowing ability frequently. 3.Allow the client sufficient time to eat. 4. Maintain a suction machine at the bedside. 5. Provide a full liquid diet for ease in swallowing.

1234 Rationale: A client who is severely dysphagic is at risk for aspiration. Swallowing is assessed frequently. The client should be given a sufficient amount of time to eat. Semisoft foods are easiest to swallow and require less chewing. Oral hygiene is necessary after each meal. Suctioning should be available for clients who experience dysphagia and are at risk for aspiration.

The home health nurse is visiting a client with myasthenia gravis and is discussing methods to minimize the risk of aspiration during meals related to decreased muscle strength. Which suggestions should the nurse give to the client? Select all that apply. 1.Chew food thoroughly. 2.Cut food into very small pieces. 3. Sit straight up in the chair while eating. 4. Lift the head while swallowing liquids. 5. Swallow when the chin is tipped slightly downward to the chest.

1235Rationale: The client avoids swallowing any type of food or drink with the head lifted upward, which could actually cause aspiration by opening the glottis. The client should be advised to sit upright while eating, not to talk with food in the mouth (talking requires opening the glottis), cut food into very small pieces, chew thoroughly, and tip the chin downward to swallow.

Cerebral palsy (CP) is a term applied to a disorder that impairs movement and posture. The effects on perception, language, and intellect are determined by the type that is diagnosed. What are the potential warning signs of CP? Select all that apply. 1.The infant's arms or legs are stiff or rigid. 2.A high risk factor for CP is very low birth weight. 3.By 8 months of age, the infant can sit without support. 4.The infant has strong head control but a limp body posture. 5.The infant has feeding difficulties, such as poor sucking and swallowing. 6.If the infant is able to crawl, only one side is used to propel himself or herself.

1256 Rationale: Options 1, 2, 5, and 6 are potential warning signs of CP. By 8 months of age, if the infant cannot sit up without support, this would be considered a potential warning sign, because this developmental task should be completed by this time. The infant with a potential diagnosis of CP has poor head control by 3 months of age, when head control should be strong.

The nurse is developing a plan of care for a child who is at risk for seizures. Which interventions apply if the child has a seizure? Select all that apply. 1.Time the seizure. 2.Restrain the child. 3.Stay with the child. 4.Place the child in a prone position. 5.Move furniture away from the child. 6. Insert a padded tongue blade in the child's mouth.

135 Rationale: A seizure is a disorder that occurs as a result of excessive and unorganized neuronal discharges in the brain that activate associated motor and sensory organs. During a seizure, the child is placed on his or her side in a lateral position. Positioning on the side prevents aspiration because saliva drains out the corner of the child's mouth. The child is not restrained because this could cause injury to the child. The nurse would loosen clothing around the child's neck and ensure a patent airway. Nothing is placed into the child's mouth during a seizure because this action may cause injury to the child's mouth, gums, or teeth. The nurse would stay with the child to reduce the risk of injury and allow for observation and timing of the seizure.

The nurse is providing home care instructions to the parents of a child with a seizure disorder. Which statement indicates to the nurse that the teaching regarding seizure disorders has been effective? 1. "We're glad we only have to give our child the medication for 30 days." 2. "We will make appointments for follow-up blood work and care as directed." 3. "We're glad there are no side effects from taking the antiseizure medications." 4. "After our child has been seizure free for 1 month, we can discontinue the medication."

2 Rationale: Antiseizure medications are continued for a prolonged time even if seizures are controlled. Periodic reevaluation of the child is important to assess the continued effectiveness of the medication, check serum medication levels, and determine the need to alter the dosage if indicated. Antiseizure medications have potential side effects, and parents should be informed of such effects specific to the medication the child will be taking. Withdrawal of medication follows a predesigned protocol, usually begun when the child has been seizure free for at least 2 years. When a medication is discontinued, the dosage should be reduced gradually over 1 to 2 weeks.

An infant with a diagnosis of hydrocephalus is scheduled for surgery. Which is the priority nursing intervention in the preoperative period? 1.Test the urine for protein. 2.Reposition the infant frequently. 3.Provide a stimulating environment. 4.Assess blood pressure every 15 minutes.

2 Rationale: Hydrocephalus occurs as a result of an imbalance of cerebrospinal fluid absorption or production that is caused by malformations, tumors, hemorrhage, infections, or trauma. It results in head enlargement and increased intracranial pressure. In infants with hydrocephalus, the head grows at an abnormal rate, and if the infant is not repositioned frequently, pressure ulcers can occur on the back and side of the head. An egg crate mattress under the head is also a nursing intervention that can help prevent skin breakdown. Proteinuria is not specific to hydrocephalus. Stimulus should be kept at a minimum because of the increase in intracranial pressure. It is not necessary to check the blood pressure every 15 minutes.

The nursing student is caring for a child with increased intracranial pressure. On review of the chart, the student nurse notes that a transtentorial herniation has occurred. The nursing instructor asks the student about this type of herniation. Which statement by the student indicates a need for further research about this condition? 1."The herniation can be unilateral or bilateral." 2."It involves only anterior portions of the brain." 3."It can cause death if large amounts of tissue are involved." 4."The brain herniates downward and around the tentorium cerebelli."

2 Rationale: Transtentorial herniation occurs when part of the brain herniates downward and around the tentorium cerebelli. It can be unilateral or bilateral and may involve anterior or posterior portions of the brain. If a large amount of tissue is involved, the risk of death is increased because vital brain structures are compressed and become unable to perform their function.

The nurse has given the client with Bell's palsy instructions on preserving muscle tone in the face and preventing denervation. The nurse determines that the client needs additional teaching if the client makes which statements? 1."I will perform facial exercises." 2."I will expose my face to cold to decrease the pain." 3."I will massage my face with a gentle upward motion." 4."I will wrinkle my forehead, blow out my cheeks, and whistle frequently."

2 ationale: Exposure to cold or drafts is avoided in Bell's palsy because it can cause discomfort. Prevention of muscle atrophy with Bell's palsy is accomplished with facial massage, facial exercises, and electrical nerves stimulation. Local application of heat to the face may improve blood flow and provide comfort.

The nurse is developing a plan of care for a newborn infant with spina bifida (myelomeningocele type). The nurse includes assessment measures in the plan to monitor for increased intracranial pressure. Which assessment technique should be performed that will best detect the presence of an increase in intracranial pressure? 1.Check urine for specific gravity. 2.Monitor for signs of dehydration. 3.Assess anterior fontanel for bulging. 4.Assess blood pressure for signs of hypotension.

3 Rationale: A bulging or taut anterior fontanel would indicate the presence of increased intracranial pressure. Urine concentrating ability is not well developed at the newborn stage of development. Monitoring for signs of dehydration will not provide data related to increased intracranial pressure. Blood pressure is difficult to assess during the newborn period and is not the best indicator of intracranial pressure.

A nurse is reviewing the record of a child with increased intracranial pressure and notes that the child has exhibited signs of decerebrate posturing. Which assessment finding should the nurse expect if this type of posturing were present? 1.Flexion of the upper extremities and extension of the lower extremities 2.Unilateral or bilateral postural change in which the extremities are rigid 3.Abnormal extension of the upper and lower extremities with some internal rotation 4.Arms are adducted with fists clenched and the legs are flaccid with external rotation

3 Rationale: Decerebrate (extension) posturing is an abnormal extension of the upper extremities, with internal rotation of the upper arm and wrist and extension of the lower extremities with some internal rotation. Option 1 describes decorticate posturing. Options 2 and 4 are incorrect and not characteristics of decerebrate posturing.

he nurse is providing instructions to the parents of an infant with a ventriculoperitoneal shunt. The nurse should include which instruction? 1.Expect an increased urine output from the shunt. 2.Notify the health care provider if the infant is fussy. 3.Call the health care provider if the infant has a high-pitched cry. 4.Position the infant on the side of the shunt when the infant is put to bed.

3 Rationale: If the shunt is malfunctioning, the fluid from the ventricle part of the brain will not be diverted to the peritoneal cavity. The cerebrospinal fluid will build up in the cranial area. The result is increased intracranial pressure, which then causes a high-pitched cry in the infant. The infant should not be positioned on the side of the shunt because this will cause pressure on the shunt and skin breakdown. This type of shunt affects the gastrointestinal system, not the genitourinary system, and an increased urinary output is not expected. Being fussy is a concern only if other signs indicative of a complication are occurring.

A nurse is monitoring an infant for signs of increased intracranial pressure (ICP). On assessment of the fontanelles, the nurse notes that the anterior fontanelle bulges when the infant is sleeping. Based on this finding, which is the priority nursing action? 1.Increase oral fluids. 2.Document the finding. 3.Notify the health care provider. 4.Place the infant supine in a side-lying position.

3 Rationale: The anterior fontanelle is diamond shaped and is located on the top of the head. It should be soft and flat in a normal infant, and it normally closes by 12 to 18 months of age. A larger-than-normal fontanelle may be a sign of increased ICP within the skull. Although the anterior fontanelle may bulge slightly when the infant cries, bulging at rest may indicate increased ICP. Options 1 and 4 are inaccurate interventions and will not be helpful. Although the nurse would document the finding, the priority action would be to report the finding to the health care provider.

The nurse enters a child's room and discovers that the child is having a seizure. Which actions should the nurse take? Select all that apply. 1. Call a code. 2. Run to get the crash cart. 3. Turn the child on her side. 4. Loosen any restrictive clothing. 5. Check the child's respiratory status. 6. Place an airway into the child's mouth.

345 Rationale: During a seizure the child is placed on his or her side in a lateral position. Positioning on the side will prevent aspiration because saliva will drain out the corner of the child's mouth. The child is not restrained because this could cause injury to the child. The nurse would loosen clothing around the child's neck and ensure a patent airway by checking respiratory status. A code would be called if the child was not breathing or the heart is not beating. There are no data in the question indicating that this is the case. The nurse would stay with the child to reduce the risk of injury and allow for observation and timing of the seizure. Nothing is placed into the child's mouth during a seizure because this could injure the child's mouth, gums, or teeth.

The nurse assists a health care provider in performing a lumbar puncture on a 3-year-old child with leukemia in whom central nervous system disease is suspected. In which position will the nurse place the child during this procedure? 1.Lithotomy position 2.Modified Sims position 3.Prone with knees flexed to the abdomen and head bent with chin resting on the chest 4.Lateral recumbent position with the knees flexed to the abdomen and head bent with the chin resting on chest

4 Rationale: A lateral recumbent position with the knees flexed to the abdomen and the head bent with the chin resting on the chest is assumed for a lumbar puncture. This position separates the spinal processes and facilitates needle insertion into the subarachnoid space. Options 1, 2, and 3 are incorrect positions.

A nurse caring for a child who has sustained a head injury in an automobile crash is monitoring the child for signs of increased intracranial pressure (ICP). For which early sign of increased ICP should the nurse monitor? 1.Increased systolic blood pressure 2.Abnormal posturing of extremities 3.Significant widening pulse pressure 4.Changes in level of consciousness (LOC)

4 Rationale: An altered level of consciousness is an early sign of increased ICP. Late signs of increased ICP include tachycardia leading to bradycardia, apnea, systolic hypertension, widening pulse pressure, and posturing.

The nurse is providing home care instructions to the mother of a child who is recovering from Reye's syndrome. Which instruction should the nurse provide to the mother? 1.Increase stimuli in the home environment. 2.Avoid daytime naps so that the child will sleep at night 3.Give the child frequent small meals, if vomiting occurs. 4. Check the skin and eyes every day for a yellow discoloration.

4 Rationale: Checking for jaundice will assist in identifying the presence of liver complications, which are characteristic of Reye's syndrome. Decreasing stimuli and providing rest decrease stress on the brain tissue. If vomiting occurs in Reye's syndrome, it is caused by cerebral edema and is a sign of intracranial pressure.

The nurse is caring for an infant with spina bifida (myelomeningocele type) who had the sac on the back containing cerebrospinal fluid, the meninges, and the nerves (gibbus) surgically removed. The nursing plan of care for the postoperative period should include which nursing action to maintain the infant's safety? 1.Covering the back dressing with a binder 2. Placing the infant in a head-down position 3. Strapping the infant in a baby seat sitting up 4. Elevating the head with the infant in the prone position

4 Rationale: Elevating the head will decrease the chance that cerebrospinal fluid will accumulate in the cranial cavity. The infant needs to be prone or side-lying to decrease the pressure on the surgical site on the back. Binders and a baby seat should not be used because of the pressure they would exert on the surgical site.

A nurse notes that an infant with the diagnosis of hydrocephalus has a head that is heavier than that of the average infant. The nurse should determine that special safety precautions are needed when moving the infant with hydrocephalus. Which statement should the nurse plan to include in the discharge teaching with the parents to reflect this safety need? 1."Feed your infant in a side-lying position." 2. "Place a helmet on your infant when in bed." 3. "Hyperextend your infant's head with a rolled blanket under the neck area." 4. "When picking up your infant, support the infant's neck and head with the open palm of your hand."

4 Rationale: Hydrocephalus is a condition characterized by an enlargement of the cranium because of an abnormal accumulation of cerebrospinal fluid in the cerebral ventricular system. This characteristic causes the increase in the weight of the infant's head. The infant may experience significant head enlargement. Care must be exercised so that the head is well supported when the infant is fed or moved to prevent extra strain on the infant's neck, and measures must be taken to prevent the development of pressure areas. Supporting the infant's head and neck when picking up the infant will prevent the hyperextension of the neck area and the infant from falling backward. The infant should be fed with the head elevated for proper motility of food processing. A helmet could suffocate an unattended infant during rest and sleep times, and hyperextension of the infant's head could put pressure on the neck vertebrae, causing injury.

The community health nurse is providing information to parents of children in a local school regarding the signs of meningitis. The nurse informs the parents that the classic signs/symptoms of meningitis include which findings? 1.Nausea, delirium, and fever 2.Severe headache and back pain 3.Photophobia, fever, and confusion 4.Severe headache, fever, and a change in the level of consciousness

4 Rationale: The classic signs/symptoms of meningitis include severe headache, fever, stiff neck, and a change in the level of consciousness. Photophobia also may be a prominent early manifestation and is thought to be related to meningeal irritation. Although nausea, confusion, delirium, and back pain may occur in meningitis, these are not the classic signs/symptoms.

The nurse is assessing a child with increased intracranial pressure. On assessment, the nurse notes that the child is now exhibiting decerebrate posturing. The nurse should modify the client's plan of care based on which interpretation of the client's change? 1.An insignificant finding 2.An improvement in condition 3.Decreasing intracranial pressure 4.Deteriorating neurological function

4 Rationale: The progression from decorticate to decerebrate posturing usually indicates deteriorating neurological function and warrants health care provider notification. Options 1, 2, and 3 are inaccurate interpretations.

e nurse is caring for a newborn infant with spina bifida (myelomeningocele) who is scheduled for surgical closure of the sac. In the preoperative period, which is the priority problem? 1.Infection 2.Choking 3.Inability to tolerate stimulation 4.Delayed growth and development

1 Rationale: A myelomeningocele is a type of spina bifida that results from failure of the neural tube to close during embryonic development. With a myelomeningocele, protrusion of the meninges, cerebrospinal fluid, nerve roots, and a portion of the spinal cord occurs. The newborn with spina bifida is at risk for infection before the closure of the sac, which is done soon after birth. Initial care of the newborn with myelomeningocele involves prevention of infection. A sterile normal saline dressing is placed over the sac to maintain moisture of the sac and its contents and to prevent tearing or breakdown of the skin integrity at the site. Any opening in the sac greatly increases the risk of infection of the central nervous system. Choking and inability to tolerate stimulation are not priority problems with this defect. Delayed growth and development is a problem for the infant with myelomeningocele, but preventing infection has priority in the preoperative period.

The nurse is providing instructions to a client with a seizure disorder who will be taking phenytoin (Dilantin). Which statement, if made by the client, would indicate an understanding of the information about this medication? 1."I need to perform good oral hygiene, including flossing and brushing my teeth." 2."I should try to avoid alcohol, but if I'm not able to, I can drink alcohol in moderation." 3. "I should take my medication before coming to the laboratory to have a blood level drawn." 4. "I should monitor for side effects and adjust my medication dose depending on how severe the side effects are."

1 Rationale: The client should perform good oral hygiene, including flossing and brushing the teeth. The client also should see a dentist at regularly scheduled times because gingival hyperplasia is a side effect of this medication. The client should avoid alcohol while taking this medication. The client should also be instructed that follow-up serum blood levels are important and that, on the day of the scheduled laboratory test, the client should avoid taking the medication before the specimen is drawn. The client should not adjust medication dosages.

a client's level of consciousness using the Glasgow Coma Scale. The student understands that which categories of client functioning are included in this assessment? Select all that apply. 1.Eye opening 2.Reflex response 3.Best verbal response 4.Best motor response 5.Pupil size and reaction

134 Rationale: Assessment of pupil size and reaction and reflex response are not part of the Glasgow Coma Scale. The three categories included are eye opening, best verbal response, and best motor response. Pupil assessment and reflex response is a necessary part of a total assessment of the neurological status of a client but is not part of this particular scale.

Which nursing actions apply to the care of a child who is having a seizure? Select all that apply. 1. Time the seizure. 2. Restrain the child. 3. Stay with the child. 4. Insert an oral airway. 5. Place the child in a lateral side-lying position. 6. Loosen clothing around the child's neck.

1356 Rationale: During a seizure, the child is placed on his or her side in a lateral position. Positioning on the side prevents aspiration because saliva drains out the corner of the child's mouth. The child is not restrained because this could cause injury to the child. The nurse should loosen clothing around the child's neck and ensure a patent airway. Nothing is placed in the child's mouth during a seizure because this could injure the child's mouth, gums, or teeth. The nurse should stay with the child to reduce the risk of injury and allow for observation and timing of the seizure.

he nurse is caring for the client with increased intracranial pressure. The nurse would note which trend in vital signs if the intracranial pressure is rising? 1.Increasing temperature, increasing pulse, increasing respirations, decreasing blood pressure 2.Increasing temperature, decreasing pulse, decreasing respirations, increasing blood pressure 3.Decreasing temperature, decreasing pulse, increasing respirations, decreasing blood pressure 4.Decreasing temperature, increasing pulse, decreasing respirations, increasing blood pressure

2 Rationale: A change in vital signs may be a late sign of increased intracranial pressure. Trends include increasing temperature and blood pressure and decreasing pulse and respirations. Respiratory irregularities also may occur.

A nurse is testing the spinal reflexes of a client during neurological assessment. Which reflex will assist in determining that the client has an adequate spinal reflex? 1.Cough reflex 2.Withdrawal reflex 3.Accommodation reflex 4.Munroe-Kellie reflex

2 Rationale: The withdrawal reflex is one of the spinal reflexes. It is an abrupt withdrawal of a body part in response to painful or injurious stimuli. The cough reflex is a brainstem-associated reflex. Accommodation reflex is associated with cranial nerve III and is part of the ocular motor system. Munroe-Kellie is not a reflex; it is a doctrine or a hypothesis addressing the cerebral volume relationships among the brain, the cerebrospinal fluid, and intracranial blood and their cumulative impact on intracranial pressure.

The nurse receives a telephone call from the admissions office and is told that a child with acute bacterial meningitis will be admitted to the pediatric unit. The nurse prepares for the child's arrival and plans to implement which type of precautions? 1.Enteric 2.Contact 3.Droplet 4.Neutropenic

3 Rationale: A major priority in nursing care for a child with suspected meningitis is to administer the appropriate antibiotic as soon as it is prescribed. The child will be placed in a private room, with droplet transmission precautions, for at least 24 hours after antibiotics are given. Enteric, contact, and neutropenic precautions are not associated with the mode of transmission of meningitis. Enteric precautions are instituted when the mode of transmission is through the gastrointestinal tract. Contact precautions are instituted when contact with infectious items or materials is likely. Neutropenic precautions are instituted when the client has a low neutrophil count.

A client has been diagnosed with Alzheimer's disease. The nurse concludes that the client has a pathological condition of which components of the nervous system? 1.Glia 2.Peripheral nerves 3. Neuronal dendrites 4. Monoamine oxidase

3 Rationale: Alzheimer's disease is characterized by changes in the dendrites of the neurons. The decrease in the number and composition of the dendrites is responsible for the symptoms of the disease. The components in the other options are not related to the pathology of Alzheimer's disease.

The home care nurse is performing an assessment on a client with a diagnosis of Bell's palsy. Which assessment question will elicit the most specific information regarding this client's disorder? 1."Do your eyes feel dry?" 2."Do you have any spasms in your throat?" 3."Are you having any difficulty chewing food?" 4."Do you have any tingling sensations around your mouth?"

3 Rationale: Bell's palsy is a one-sided facial paralysis caused by compression of the facial nerve. Manifestations include facial droop from paralysis of the facial muscles; increased lacrimation; painful sensations in the eye, face, or behind the ear; and speech or chewing difficulties.

The nurse has provided instructions to a client with a diagnosis of myasthenia gravis about home care measures. Which client statement indicates the need for further instruction? 1. "I will rest each afternoon after my walk." 2. "I should cough and deep breathe many times during the day." 3. "I can change the time of my medication on the mornings when I feel strong." 4. "If I get abdominal cramps and diarrhea, I should call my health care provider."

3 Rationale: The client with myasthenia gravis and his or her family should be taught information about the disease and its treatment. They should be aware of the side and adverse effects of anticholinesterase medications and corticosteroids and should be taught that timing of anticholinesterase medication is critical. It is important to instruct the client to administer the medication on time to maintain a chemical balance at the neuromuscular junction. If it is not given on time, the client may become too weak to even swallow. Resting after a walk, coughing and deep breathing many times over the day, and calling the health care provider when experiencing abdominal cramps and diarrhea indicate correct understanding of home care instructions to maintain health with this neurological degenerative disease.

A client has dysfunction of the cochlear division of the vestibulocochlear nerve (cranial nerve VIII). The nurse should determine that the client is adequately adapting to this problem if he or she states a plan to obtain which item? 1.A walker 2.Eyeglasses 3.A hearing aid 4. A bath thermometer

3 Rationale: The cochlear division of cranial nerve VIII is responsible for hearing. Clients with hearing difficulty may benefit from the use of a hearing aid. The vestibular portion of this nerve controls equilibrium; difficulty with balance caused by dysfunction of this division could be addressed with use of a walker. Eyeglasses would correct visual problems (cranial nerve II); a bath thermometer would be of use to clients with sensory deficits of peripheral nerves, such as with diabetic neuropathy.

The post-head injury client opens eyes to sound, has no verbal response, and localizes to painful stimuli when applied to each extremity. How should the nurse document the Glasgow Coma Scale (GCS) score? 1.GCS = 3 2. GCS = 6 3. GCS = 9 4. GCS = 11

3Rationale: The GCS is a method is assessing neurological status. The highest possible score in the GCS is 15. A score lower than 8 indicates that coma is present. Motor response points are as follows: Obeys a simple response = 6; Localizes painful stimuli = 5; Normal flexion (withdrawal) = 4; Abnormal flexion (decorticate posturing) = 3; Extensor response (decerebrate posturing) = 2; No motor response to pain = 1. Verbal response points are as follows: Oriented = 5; Confused conversation = 4; Inappropriate words = 3; Responds with incomprehensible sounds = 2; No verbal response = 1. Eye opening points are as follows: Spontaneous = 4; In response to sound = 3; In response to pain = 2; No response, even to painful stimuli = 1. Using the GCS, a score of 3 is given when the client opens the eyes to sound. Localization to pain is scored as 5. When there is no verbal response the score is a 1. The total score is then equal to 9.

The nurse is preparing for the admission of a client with a suspected diagnosis of Guillain-Barré syndrome. When the client arrives at the nursing unit, the nurse reviews the health care provider's documentation. The nurse expects to note documentation of which hallmark clinical manifestation of this syndrome? 1. Multifocal seizures 2. Altered level of consciousness 3. Abrupt onset of a fever and headache 4. Development of progressive muscle weakness

4 Rationale: A hallmark clinical manifestation of Guillain-Barré syndrome is progressive muscle weakness that develops rapidly. Seizures are not normally associated with this disorder. The client does not have symptoms such as a fever or headache. Cerebral function, level of consciousness, and pupillary responses are normal.

The nurse is performing an assessment of a 7-year-old child who is suspected of having episodes of absence seizures. Which assessment question to the mother will assist in providing information that will identify the symptoms associated with this type of seizure? 1. "Does twitching occur in the face and neck?" 2. "Does the muscle twitching occur on one side of the body?" 3. "Does the muscle twitching occur on both sides of the body?" 4. "Does the child have a blank expression during these episodes?"

4 Rationale: Absence seizures are brief episodes of altered awareness or momentary loss of consciousness. No muscle activity occurs except eyelid fluttering or twitching. The child has a blank facial expression. These seizures last only 5 to 10 seconds, but they may occur one after another several times a day. Simple partial seizures consist of twitching of an extremity, face, or neck, or the sensation of twitching or numbness in an extremity or face or neck. Myoclonic seizures are brief random contractions of a muscle group that can occur on one or both sides of the body.

A nurse caring for an infant with a diagnosis of hydrocephalus should monitor the infant for which sign of increased intracranial pressure (ICP)? 1.Proteinuria 2.Bradycardia 3.A drop in blood pressure 4.A bulging anterior fontanel

4 Rationale: An elevated or bulging anterior fontanel indicates an increase in cerebrospinal fluid collection in the cerebral ventricle. Proteinuria, bradycardia, and a drop in blood pressure are not specific signs of increased ICP. Changes in the level of consciousness and a widened pulse pressure are additional signs of increased ICP.

The nurse is caring for a client with trigeminal neuralgia (tic douloureux). The client asks for a snack and something to drink. The nurse should offer which best snack to the client? 1.Cocoa with honey and toast 2.Hot herbal tea with graham crackers 3.Iced coffee and peanut butter and crackers 4.Vanilla wafers and room-temperature water

4 Rationale: Because mild tactile stimulation of the face can trigger pain in trigeminal neuralgia, the client needs to eat or drink lukewarm, nutritious foods that are soft and easy to chew. Extremes of temperature will cause trigeminal nerve pain. Therefore, options 1, 2, and 3 are incorrect.

The nurse is teaching a client hospitalized with a seizure disorder and the client's spouse about safety precautions after discharge. The nurse determines that the client needs more information if he or she states an intention to take which action? 1.Refrain from smoking alone. 2.Take all prescribed medications on time. 3.Have the spouse nearby when showering. 4.Drink alcohol in small amounts and only on weekends.

4 Rationale: The client should avoid the intake of alcohol. Alcohol could interact with the client's seizure medications, or the alcohol could precipitate seizure activity. The client should take all medications on time to avoid decreases in therapeutic drug levels, which could precipitate seizures. The client should not bathe in the shower or tub without someone nearby and should not smoke alone, to minimize the risk of injury if a seizure occurs.

The nurse is admitting a client with Guillain-Barré syndrome to the nursing unit. The client has ascending paralysis to the level of the waist. Knowing the complications of the disorder, the nurse should bring which most essential items into the client's room? 1.Nebulizer and pulse oximeter 2.Blood pressure cuff and flashlight 3.Flashlight and incentive spirometer 4.Electrocardiographic monitoring electrodes and intubation tray

4 Rationale: The client with Guillain-Barré syndrome is at risk for respiratory failure because of ascending paralysis. An intubation tray should be available for use. Another complication of this syndrome is cardiac dysrhythmias, which necessitates the use of electrocardiographic monitoring. Because the client is immobilized, the nurse should assess for deep vein thrombosis and pulmonary embolism routinely. Although items in the incorrect options may be used in care, they are not the most essential items from the options provided.

The home health nurse has been discussing interventions to prevent constipation in a client with multiple sclerosis. The nurse determines that the client is using the information most effectively if the client reports which action? 1.Drinking a total of 1000 mL/day 2.Giving herself an enema every morning before breakfast 3.Taking stool softeners daily and a glycerin suppository once a week 4. Initiating a bowel movement every other day, 45 minutes after the largest meal of the day

4 Rationale: To manage constipation, the client should take in a high-fiber diet, bulk formers, and stool softeners. A fluid intake of 2000 mL/day is recommended. The client should initiate the bowel program on an every-other-day basis. This should be done approximately 45 minutes after the largest meal of the day to take advantage of the gastrocolic reflex. A glycerin suppository, bisacodyl suppository, or digital stimulation may be used to initiate the process. Laxatives and enemas should be avoided whenever possible because they lead to dependence.

A mother arrives at an emergency department with her 5-year-old child and states that the child fell off a bunk bed. A head injury is suspected, and the nurse checks the child's airway status and assesses the child for early and late signs of increased intracranial pressure (ICP). Which is a late sign of increased ICP? 1.Nausea 2.Irritability 3.Headache 4. Bradycardia

4Rationale: Head injury is the pathological result of any mechanical force to the skull, scalp, meninges, or brain. A head injury can cause bleeding in the brain and result in increased intracranial pressure (ICP). In a child, early signs include a slight change in level of consciousness, headache, nausea, vomiting, visual disturbances (diplopia), seizures. Late signs of increased ICP include a significant decrease in level of consciousness, bradycardia, decreased motor and sensory responses, alterations in pupil size and reactivity, posturing, Cheyne-Stokes respirations, and coma.

A client with trigeminal neuralgia asks the nurse what causes the painful episodes associated with the condition. The nurse's response is based on an understanding that the symptoms can be triggered by which process? 1.A local reaction to nasal stuffiness 2.A hypoglycemic effect on the cranial nerve 3.Release of catecholamines with infection or stress 4. Stimulation of the affected nerve by pressure and temperature

4Rationale: The paroxysms of pain that accompany this neuralgia are triggered by stimulation of the terminal branches of the trigeminal nerve. Symptoms can be triggered by pressure from washing the face, brushing the teeth, shaving, eating, or drinking. Symptoms also can be triggered by thermal stimuli, such as a draft of cold air. Options 1, 2, and 3 are incorrect.
