What will the nurse recommend to the client starting therapy with meclizine (Antivert)?

"Avoid caffeinated coffee or soft drinks while taking this medication." Antivert can cause dry mouth, which can be made worse by the consumption of caffeinated beverages

Which precautions or instruction should the nurse teach the client who is going to have electroretinography of the eye?

"Avoid rubbing your eyes until the anesthetic drops have worn off." The client could inadvertently scratch or harm the eye by touching or rubbing it while the anesthetic effect is present.

Which recommendation will the nurse provide for the client with Ménière's disease who has periodic spells of vertigo?

"Avoid wearing high-heeled shoes." Clients with vertigo should wear low-heeled shoes with non-skid soles and tied laces to prevent injury

Which instruction will the nurse provide about a cephalexin (Keflex) prescription that the client will be taking at home after tympanoplasty surgery?

"Be sure to finish all the Keflex pills, even if you feel fine." Keflex is an antibiotic. Clients should be sure to take the entire course of therapy to prevent the development of infection with resistant microorganisms

Which is the most important information for the nurse to teach a client who is receiving cycloplegic drug therapy?

"Do not drive or operate machinery until the drug wears off." Cycloplegic agents prevent accommodation of the iris, resulting in a widely dilated pupil

The client is prescribed phenytoin (Dilantin) for treatment of a seizure disorder. What precautions or instructions should be taught to this client?

"Do not take warfarin (Coumadin) while on this medication." Warfarin inhibits the metabolism of phenytoin, increasing the half-life of phenytoin and the risk of toxic levels.

When interviewing an acutely confused patient with a head injury, which of these questions will provide the most useful information?

"Do you have any pain at the present time?" The acutely confused patient will be able to state whether there is pain currently

Atonic Seizure

"Drop Attack " The primary drugs to treat generalized tonic-clonic and partial seizures are phenytoin (Dilantin), carbamazepine (Tegretol), phenobarbital, and divalproex (Depakote). (Lewis 1496)

When the nurse is taking a health history of a new patient at the ear clinic, the patient states, "I always sleep with the radio on." Which response by the nurse is most appropriate?

"Have you noticed any ringing in your ears?" Patients with tinnitus may use masking techniques, such as playing a radio, to block out the ringing in the ears

The health care provider prescribes phenytoin (Dilantin) for control of complex partial seizures. After the nurse has taught the patient about phenytoin, which patient statement indicates understanding of the medication?

"I may need to have my blood taken frequently to check the level of the Dilantin." Serum levels of phenytoin may be checked to ascertain that a therapeutic level of the medication is achieved

The nurse is obtaining a health history for a 64-year-old patient with glaucoma who is a new patient at the eye clinic. Which information given by the patient will have the most implications for the patient's treatment?

"I take metoprolol (Lopressor) daily for angina." It is important to note whether the patient takes any beta-adrenergic blockers because this category of medications is also used to treat glaucoma and there may be an increase in adverse effects.

The client with long-standing primary open-angle glaucoma and loss of 60% of her visual fields is about to undergo surgical treatment to create a new drainage channel for the aqueous humor. Which of the following statements made by the client indicates a lack of understanding regarding this treatment?

"I will probably not regain my total vision again for at least 2 weeks." Surgery for glaucoma does not correct vision that is lost; it relieves pressure to prevent further loss

Which statement indicates that the client needs additional teaching about protecting the ears and preventing hearing loss?

"I will take Motrin (ibuprofen) instead of Tylenol (acetaminophen), as needed, for my arthritis pain." Motrin (ibuprofen) can be ototoxic. Its use should be avoided to help prevent additional hearing loss

A patient with age-related macular degeneration has just had photodynamic therapy. Which statement by the patient indicates that the discharge teaching has been effective?

"I will wear a hat, long-sleeved shirt, and pants for the next 5 days." The photosensitizing drug used for photodynamic therapy is activated by exposure to bright light and can cause burns in areas exposed to light for 5 days after the treatment.

The client requires a hearing aid but tells the nurse that he cannot afford to pay for it right now. What is the nurse's best response?

"I'll ask the social worker to check if any local organizations help people pay for hearing aid."

A graduate nurse is orienting to the neurologic ICU. The new nurse asks their preceptor what is meant by "lacunar" stroke. What would be the preceptor's best reply?

"Lacunar strokes are small-artery thrombotic strokes."

The nurse talking with a client with open-angle glaucoma would instruct the client to make a behavior change based on the statement

"Now that the allergy season is here, I take antihistamines on a regular basis." Many over-the-counter (OTC) medications, including antihistamines, can dilate the pupil, putting the client at risk for angle-closure glaucoma.

A patient with otosclerosis has a stapedectomy for treatment of hearing loss. Two days after the surgery, the patient tells the nurse, "I do not hear as well now as I did right after the surgery." Which response by the nurse is most appropriate?

"Postoperative accumulation of fluid and blood in your middle ear will temporarily decrease your hearing." Patients frequently have improved hearing immediately after surgery, which decreases postoperatively because of the accumulation of blood and drainage in the ear. The hearing will improve again as healing occurs.

The client has been treated with radiation therapy to the eye. What will the nurse teach the client?

"See your ophthalmologist for a complete eye examination yearly."

Which lifestyle modification should the nurse suggest to the client with Ménière's disease to reduce the frequency or intensity of acute episodes?

"Stop or reduce cigarette smoking." The vasoconstrictive effects of cigarette smoking reduce endolymph absorption and promote acute episodes of Ménière's disease.

Timolol (Timoptic) ophthalmic drops are prescribed for a patient with open-angle glaucoma. After using the drops for several days, the patient tells the nurse that the eyedrops cause eye burning and visual blurriness for a time. The best response by the nurse to the patient's complaint is,

"The drops are uncomfortable, but it is very important for you to use them as prescribed to retain your vision." : Patients should be instructed that eye discomfort and visual blurring are expected side effects of the ophthalmic drops but that the drops must be used to prevent further visual-field loss.

When obtaining a health history from a 52-year-old patient, which patient statement will be of most concern to the nurse?

"The middle part of my vision is decreased." The decrease in vision in the center of the visual field may indicate macular degeneration, which is not a normal visual change associated with aging

Family members are optimistic about a comatose patient's recovery because the patient's eyes open and the patient appears to be awake at times. Which statement by the nurse to the family is appropriate?

"The part of the brain responsible for arousal is not injured, but the wakefulness does not indicate improvement in higher brain centers." The behaviors of eye opening and wakefulness are not indicators of improvement in the comatose condition.

Which teaching is essential for the client who is going for intraocular pressure measurement?

"The test is quick and a local anesthetic is used." The different ways to measure intraocular pressure are performed with the eye anesthetized so that there is no pain

The nurse is caring for a client with Ménière's disease. What will the nurse recommend to the client to reduce the symptoms of vertigo?

"When dizziness begins, lie down and keep your head still."

A patient in the neurologic intensive care unit has an endotracheal tube. When the nurse does the hourly Glasgow Coma Scale assessment, what rating would this patient have for verbal response?

1 The Glasgow Coma Scale assesses both level of consciousness and motor response to a stimulus. The scale has three sections: eye opening, motor response, and verbal response. If the patient is unable to talk because of intubation, the score is a 1

Normal IOP

10-21 mm Hg

A patient with a head injury opens the eyes to verbal stimulation, curses when stimulated, and does not respond to a verbal command to move but attempts to remove a painful stimulus. The nurse records the patient's Glasgow Coma Scale score as

11 The patient has a score of 3 for eye opening, 3 for best verbal response, and 5 for best motor response.

Legal Blindness Value

20/200

A patient has been declared legally blind. This means that the patient has a best corrected visual acuity (BCVA) that does not exceed what in the better eye?

20/200 Blindness is defined as a best corrected visual acuity (BCVA) that can range from 20/400 to no light perception (NLP). The clinical definition of absolute blindness is the absence of light perception. Legal blindness is a condition of impaired vision in which a person has a BCVA that does not exceed 20/200 in the better eye or whose widest visual field diameter is 20 degrees or less

A 2-year-old girl is scheduled to have a myringotomy. How long would the nurse tell the parents that it will take for the incision to heal?

24 to 72 hours

The nursing instructor is teaching the Level 1 nursing students the proper way to instill eye drops in a patient's eye. How long would the instructor teach the students to wait between successive eye drops in the same eye to achieve adequate eye drop drug retention and absorption?

5 minutes A 5-minute interval between successive eye drop administration allows for adequate drug retention and absorption. Any timeframe less than 5 minutes will not allow adequate absorption.

The nurse explains that irreversible brain tissue damage is probable when the blood flow to the brain is reduced by

60%. When blood flow to the brain is reduced by 40%, cerebral tissue becomes acidotic. When the blood flow to the brain is reduced by 60% the electroencephalogram (EEG) pattern changes and the client is at risk for significant brain tissue damage. Cerebral metabolism is altered, which eventually leads to brain tissue hypoxia and areas of brain tissue ischemia.

CPP Normal Value

60-100

For which client does the nurse suspect secondary open-angle glaucoma?

78-year-old client who has a decreased sense of peripheral vision on the fourth postoperative day after cataract surgery with lens replacement Eye surgery is a common cause of secondary open-angle glaucoma.

A patient with a head injury has an intracranial pressure (ICP) of 18 mm Hg. Her blood pressure is 144/90 mm Hg, and her mean arterial pressure (MAP) is 108 mm Hg. What is the cerebral perfusion pressure (CPP)?

90 mm Hg CPP = MAP - ICP. In this case, CPP = 108 mm Hg - 18 mm Hg = 90 mm Hg.

When planning care for a patient with increased intracranial pressure the nurse realizes that the cerebral perfusion pressure must be maintained at

> 70 mm Hg.

The nurse assesses several clients. Which one is most likely to have secondary open-angle glaucoma?

A client who has recently had eye surgery Secondary open-angle glaucoma results from another condition that interferes with the drainage of aqueous humor.

Which client would be excluded as a potential donor for corneal transplantation?

A client with hepatitis B Clients of any age may donate corneas as long as the corneas are clear and the client is free from infectious disease or cancer at the time of death.

Which client is a poor candidate for photorefractive radial keratectomy?

A client with severe astigmatism Severe astigmatism is a current contraindication for photorefractive radial keratectomy because the cornea is very uneven.

The nurse is caring for a patient with an ICP of 18 mm Hg and a GCS score of 3. Following the administration of mannitol (Osmitrol), which assessment finding by the nurse indicates an appropriate response to therapy?

A decrease in ICP and an increase in urine output Osmotic diuretics draw water from normal brain cells, decreasing ICP and increasing CPP and urine output

During their pathophysiology class the nursing students study seizures. How might the instructor best describe the cause of a seizure?

A dysrhythmia in the nerve cells in one section of the brain The underlying cause of a seizure is an electrical disturbance (dysrhythmia) in the nerve cells in one section of the brain

During an assessment, a patient asks the nurse if "something is burning." The nurse realizes that this patient could be demonstrating:

A focal seizure Focal symptoms can occur in patients with brain tumors. The nurse should question the patient about any experienced symptoms such as muscle twitching or jerking of an arm or leg, abnormal smells or tastes, problems with speech, or numbness and tingling

Rhinorrhea Fluid Collection

A loose collection pad may be placed under the nose or over the ear. Do not place a dressing in the nasal or ear cavities. Instruct the patient not to sneeze or blow the nose. (Lewis 1444)

A patient is brought by ambulance to the emergency department after suffering what the family thinks is a stroke. The nurse caring for this patient is aware that an absolute contraindication for thrombolytic therapy is what?

A patient who is anticoagulated

When a client suffers a tonic-clonic seizure, the nurse should

A person having a seizure needs protection from the environment. The nurse should move objects out of the way, place some type of padding under the client's head, loosen clothing that is tight around the client's neck, turn the client to one side to facilitate draining saliva, and observe the characteristics of the seizure. Nothing should be forced into the client's mouth.

A patient with acute meningitis is receiving antibiotic therapy. The nurse realizes that another medication is used as adjuvant therapy. This medication is:

A steroid Steroids are currently recommended as adjunctive treatment of bacterial meningitis

The nurse working with an ICP monitor institutes which actions? The nurse (Select all that apply) a. administers prophylactic antibiotics as ordered. b. limits the number of times the system is opened. c. manipulates the catheter frequently to ensure patency. d. uses strict aseptic technique to change dressings.

ANS: A, B, D Intracranial monitors all carry a high risk of infection, and because of their placement an infection has serious consequences. Interventions to minimize the risk of infection include options a, b, and d. The monitoring system is manipulated as little as possible and left in for the shortest amount of time possible.

The nurse is caring for a patient admitted with new onset of slurred speech, facial droop, and left-sided weakness 8 hours ago. Diagnostic computed tomography scan rules out the presence of an intracranial bleed. Which actions are most important to include in the patient's plan of care (choose all that apply)? a. Compare frequent neurological assessments with baseline. b. Maintain CO2 level at 50 mm Hg. c. Maintain mean arterial pressure less than 130 mm Hg and systolic blood pressure less than 220 mm Hg. d. Prepare for therapeutic thrombolytic administration. e. Restrain affected limb to prevent injury.

ANS: A, C The goal for ischemic stroke is to keep the systolic blood pressure less than 220 mm Hg and the diastolic blood pressure 120 mm Hg. In hemorrhagic stroke the goal is a mean arterial pressure less than 130 mm Hg. Neurological assessments are compared with the baseline assessments performed in the ED. The elapsed time of 8 hours since onset of symptoms prohibits thrombolytic therapy.

In assessing a client with injury to the temporal lobe, the nurse correlates which clinical manifestation with this damage? (Select all that apply.) a. Memory loss b. Personality changes c. Loss of temperature regulation d. Difficulty with sound interpretation e. Speech difficulties f. Impaired taste

ANS: A, D, E Wernicke's area (language area) is located in the temporal lobe and enables processing of words into coherent thought and understanding of written or spoken words. The temporal lobe also is responsible for the auditory center's interpretation of sound and complicated memory patterns. Personality changes are related to damage to frontal lobe injury. Loss of temperature regulation is seen with damage to the hypothalamus, and impaired taste is associated with injury to the parietal lobe.

Which precautions will the nurse institute to ensure the safety of a client with epilepsy who has been hospitalized? (Select all that apply.) a. Have suction equipment at the bedside. b. Place a padded tongue at bedside. c. Permit only clear oral fluids. d. Keep bed rails up at all times. e. Maintain the client on strict bedrest. f. Ensure that the client has IV access.

ANS: A, D, F The bed rails should be up at all times while the client is in the bed to prevent an injury from a fall if the client has a seizure. Padded tongue blades may pose a danger to the client during a seizure. Be sure that oxygen and suctioning equipment with an airway are readily available. If the client does not have an IV access, insert a saline lock, especially for those clients who are at significant risk for generalized tonic-clonic seizures. The saline lock provides ready access if IV drug therapy must be given to stop the seizure.

A nurse in an outpatient surgical setting is assessing a client scheduled for cataract removal. The nurse would expect to find that the client has (Select all that apply) a. a shadow across the visual field. b. better vision in low light. c. blurred vision, photophobia, and glare. d. nausea and vomiting, worse with eye movements. e. sudden onset of acute eye pain.

ANS: B, C A cataract is an opacity of the lens. Classic manifestations are blurred or double vision, photophobia, and glare. Clients usually see better in low light. A shadow across the visual field is characteristic of retinal detachment. Nausea and vomiting, and acute eye pain often accompany acute angle-closure glaucoma, although the nausea may or may not be worse with eye movement.

In the client with medulla injury, the nurse monitors for which clinical manifestations secondary to damage to cranial nerves that emerge from the medulla? (Select all that apply.) a. Loss of smell b. Impaired swallowing c. Blink reflex d. Visual changes e. Inability to shrug shoulders f. Loss of gag reflex

ANS: B, E, F Cranial nerves IX (glossopharyngeal), X (vagus), XI (accessory), and XII (hypoglossal) emerge from the medulla, as do portions of cranial nerves VII (facial) and VIII (acoustic).

A client with acute-angle glaucoma has several medications ordered. Which medication will the nurse question? (Select all that apply.) a. Acetazolamide (Diamox) b. Pilocarpine (Pilocar) c. Atropine (Isopto Atropine) d. Latanoprost (Xalatan) e. Timolol (Timoptic) f. Epinephrine

ANS: C, F Atropine and epinephrine are mydriatics, which decrease the outflow of aqueous humor, resulting in increased intraocular pressure (IOP). Diamox is a carbonic anhydrase inhibitor that decreases the formation of aqueous humor. Pilocar is a miotic that enhances outflow of aqueous humor. Xalatan is a prostaglandin agonist that improves outflow, and Timoptic is a beta blocker that decreases the formation of aqueous humor. All these help decrease IOP.

The nurse is assessing a client for the possibility of a lens opacity. Which assessment finding confirms this problem?

Absence of a red reflex

The nurse is admitting a patient to the unit who is diagnosed with a lower motor neuron lesion. What clinical manifestations would you expect this patient to exhibit?

The client complains of eye pain and has nausea 2 hours after cataract surgery. Which is the nurse's priority intervention?

Administering oral glycerin (Osmoglyn) The only action that would lessen the intraocular pressure is the administration of oral glycerin (Osmoglyn).

During the health history, the client tells the nurse about all the following health problems. Which one increases the risk for impaired hearing?

Allergic rhinitis Allergic rhinitis can result in the collection of serous fluid in the middle ear. This fluid prevents full movement of the tympanic membrane and reduces conduction of sound waves.

A patient with a skull fracture was admitted unconscious, became conscious, and has since moved into unconsciousness again. This patient is demonstrating findings indicative of:

Therefore options A and C are incorrect.

When reviewing the results of a patient's cerebrospinal fluid analysis, the nurse will notify the health care provider about a. pH of 7.35. b. white blood cell count (WBC) of 4/ml (0.004/L). c. protein 30 mg/dl (0.30 g/L). d. glucose 30 mg/dl (1.7 mmol/L).

Answer: D The glucose level is low. The pH, WBCs, and protein values are normal.

During initial assessment of a client who has just suffered a head injury, a nurse notes that the pupils have an ovoid appearance. What is the nurse's best first action?

Anticipate intervention for increased ICP after notifying the physician. The change in pupil appearance from round to ovoid (mid-stage between normal and dilated) is an indication of increase intracranial pressure

A patient schedules annual testing for glaucoma with the ophthalmologist. Which information will be included when teaching the patient about routine glaucoma testing?

Application of a Tono-pen to the cornea of the eye will be needed. Glaucoma is caused by an increase in intraocular pressure, which would be measured using the Tono-pen

The client is 6 hours postoperative from a craniotomy. When monitoring vital signs, a nurse observes the client to have periorbital edema and ecchymosis around both eyes. What is the nurse's best first action?

Apply an ice pack to the affected area. Periorbital edema and ecchymosis are expected after a craniotomy. The nurse attempts to increase the client's comfort by reducing the swelling with application of ice.

A 32-year-old patient has a stroke resulting from a ruptured aneurysm and subarachnoid hemorrhage. Which intervention will be included in the care plan?

Applying intermittent pneumatic compression stockings The patient with a subarachnoid hemorrhage usually has minimal activity to prevent cerebral vasospasm or further bleeding and is at risk for deep vein thrombosis (DVT).

Penumbra

Around the core area of ischemia is a border zone of reduced blood flow called the penumbra, where ischemia is potentially reversible. If adequate blood flow can be restored early (i.e., within 3 hours) and the ischemic cascade can be interrupted, there may be less brain damage and less neurologic function lost (Lewis 1461)

Which nursing assessment would have highest priority for early airway management of a trauma patient?

Ask the patient to state his name. If the patient can state his name audibly then the airway is patent

Decerebrate posturing (abnormal extension) indicates dysfunction in which area of the central nervous system?

Brainstem

A nurse notes that a patient with a traumatic brain injury is having a rapid decline in level of consciousness. If the nurse suspects cerebral herniation the most appropriate intervention would be to

Briefly hyperventilate the patient Hyperventilating the patient lowers the ICP by lowering the PaCO2 that is causing vasoconstriction of the cerebral blood vessels and reducing cerebral blood flow.

A client who has had a stroke appears to understand words that are spoken but cannot verbally respond. The nurse clarifies that this type of aphasia is

Broca's. Broca's (expressive or motor) aphasia affects speech production as a result of an infarction in the frontal lobe of the brain.

CPP Calculation

CPP = MAP - ICP MAP=DBP+1/3(SBP−DBP)orSBP+2(DBP)3 Example: Systemic blood pressure = 122/84 mm Hg MAP = 97 mm Hg ICP = 12 mm Hg CPP = 85 mm Hg CPP, Cerebral perfusion pressure; DBP, diastolic blood pressure; ICP, intracranial pressure; MAP, mean arterial pressure; SBP, systolic blood pressure (Lewis 1426)

Which of the following laboratory values and observations noted on testing a client's CSF is indicative of viral meningitis?

Clear, increased protein level; normal glucose level Viral meningitis does not cause cloudiness or increased turbidity of the CSF. There are slightly increased protein and normal glucose levels. In bacterial meningitis, the presence of bacteria and white blood cells cause the fluid to be cloudy

A client has paralysis of the right medial rectus muscle of the right eye. Which assessment finding assists the nurse in validating this diagnosis?

Client is unable to turn the eye in toward the nose.

The client is receiving warfarin therapy after a thrombotic stroke. Which of the following international normalized ratios (INR) indicates that anticoagulation is adequate?

Client's INR is 2.0 to 3.0. Therapeutic INR values for clients receiving warfarin should range between 2 and 3 times the control value.

Following surgery for a pituitary tumor, when the client develops diabetes insipidus, the nurse explains that the drug that will be helpful to remedy the manifestations is

Clients who have diabetes insipidus after pituitary surgery often require IV vasopressin (Pitressin) or desmopressin (DDAVP).

The cerebrospinal (CSF) fluid laboratory finding the nurse would expect in a client with bacterial meningitis is

Clients with bacterial meningitis show the following: elevated CSF pressures, elevated CSF protein, decreased CSF glucose, and usually increased cell count with predominantly polymorphonuclear leukocytes.

Clonus

The client has a sensorineural hearing loss. Which assistive device, technique, or corrective procedure is most likely to increase this client's hearing?

Cochlear implant Hearing aids and tympanoplasty can improve the hearing of a person with a conductive hearing loss but are of minimal benefit for sensorineural hearing loss. A cochlear implant can restore some degree of hearing for clients with sensorineural hearing loss.

A patient with hearing loss asks the nurse about the use of a cochlear implant. Which information will the nurse include when replying to the patient?

Cochlear implants require training in order to receive the full benefit. Extensive rehabilitation is required after cochlear implants in order for patients to receive the maximum benefit

Glycerol Test

The patient takes 3 antihypertensive medications.

When assessing a patient with bacterial meningitis, the nurse obtains all of the following information. Which should be reported immediately to the health care provider?

The patient's blood pressure is 86/42 mm Hg. Shock is a serious complication of meningitis, and the patient's low blood pressure indicates the need for interventions such as fluids or vasopressors

The nursing instructor is discussing the difference between sensorineural and conductive hearing loss with his class. The discussion turns to evaluation for determining what kind of hearing loss a client has. What Weber test results would indicate the presence of a sensorineural loss?

The sound is heard better in the ear in which hearing is better. A client with sensorineural hearing loss hears the sound better in the ear in which hearing is better. The Weber test assesses bone conduction of sound and is used for assessing unilateral hearing loss. A tuning fork is used. A client with normal hearing hears the sound equally in both ears or describes the sound as centered in the middle of the head. A client whose hearing loss is conductive hears the sound better in the affected ear.

The client with acute otitis media experiences a sudden decrease in ear pain. What does the nurse interpret this to mean?

The tympanic membrane has spontaneously perforated. Spontaneous perforation of the tympanic membrane during acute otitis media relieves the pressure on middle ear structures and results in a sudden decrease or elimination of pain.

The nurse notes all these assessment data when examining a patient's auditory canal and tympanic membrane. Which one is of most concern?

The tympanum is bluish-tinged. A bluish-tinged tympanum can occur with acute otitis media, which requires immediate care to prevent perforation of the tympanum

A client admitted the previous day for a suspected neurologic disorder becomes increasingly lethargic. What conclusion can the nurse draw from this observation?

There has been a decline in the client's central neurologic function.

Emergency treatment of coma of unknown cause includes rapid intravenous administration of which three agents?

Thiamine, glucose, narcotic antagonist When the cause of coma is not immediately known, intravenous administration of glucose is indicated to reverse possible hypoglycemic coma. Thiamine must be administered before the glucose because thiamine deficiency coma (Wernicke's encephalopathy) can be precipitated by the glucose load. Administration of a narcotic antagonist will reverse coma caused by narcotic overdose.

On initial assessment of a patient hospitalized following a stroke, the nurse finds the patient's blood pressure to be 180/90 mm Hg. Which of the following orders by the health care provider should the nurse question?

Titrate labetolol (Normodyne) drip to keep BP less than 140/90 mm Hg Since elevated BP may be a protective response to maintain cerebral perfusion, antihypertensive therapy is recommended only if MAP is >130 mm Hg or systolic pressure is >220 mm Hg

The nurse in the eye clinic is examining a 44-year-old patient who says "I see small spots that move around in front of my eyes." Which action will the nurse take first?

Use an ophthalmoscope to examine the posterior chamber and retina of the patient's eyes Although "floaters" are usually caused by vitreous liquefaction and are common in aging patients, they can be caused by hemorrhage into the vitreous humor or by retinal tears, so the nurse's first action will be to examine the retina and posterior chamber

When assessing a sedated patient, the nurse notes that the patient blinks only five or six times a minute. The nurse should plan to

Use artificial tears every hour Because blinking usually occurs about 15 times per minute, the patient is at risk for corneal drying and abrasions unless the eye is kept lubricated using artificial tears

What method of communication can be used with a hearing-impaired patient?

Using gestures

Which of the following structures form(s) the blood-brain barrier?

Vascular endothelial cells

A week after a client experienced a ruptured cerebral aneurysm, he becomes extremely indecisive and has frequent episodes of incontinence. The nurse reports these events as probable

Whisper test

Which is the best approach for the nurse to use to obtain a history from a client with sudden hearing loss?

Write out the questions for the client to answer.

The nurse caring for a client after keratoplasty (corneal transplantation) would assess the client for possible graft rejection, as indicated by

a cloudy, swollen cornea.

An important age-related consideration the nurse should include in the care plan for an elderly client with a seizure disorder is

a decreased serum albumin level can increase the free plasma level of medications. Protein-calorie malnutrition is common among elders and the subsequent decreased serum albumin level can lead to increased plasma levels of the drug, making them prone to drug toxicities. Many seizure medications do have multiple drug-drug interactions, but all are available for use in this population. The frequency of seizures being diagnosed in the elderly population is increasing.

Mr. G has suffered an ischemic stroke involving the left cerebral hemisphere. Which of the following neurologic abnormalities would you expect to see? Select all that apply. a. Aphasia b. Left visual field defect c. Difficulty balancing his checkbook d. Ataxic gait e. Somnolence

a, c Rationale: While this type of stroke can affect speech and cognitive functions such as addition or subtraction, there is usually not a change in LOC.

Mrs. M has been admitted with a subarachnoid hemorrhage (SAH). While reviewing her history you would expect to see which of the following prior symptoms? Select all that apply. a. Abrupt onset of severe headache b. Extended loss of consciousness c. Nausea and vomiting d. Photophobia e. Diffuse left-sided weakness

a, c, d Rationale: A key symptom in diagnosing SAH is the patients complaint of "the worst headache I've ever had." Loss of consciousness and weakness are not necessarily present at onset.

A patient with a stroke experiences right-sided arm and leg paralysis and facial drooping on the right side. When obtaining admission assessment data about the patient's clinical manifestations, it is most important the nurse assess the patient's

ability to follow commands.

A patient in the intensive care unit continues to seizure after receiving Ativan. He currently has an intravenous infusion of Dextrose 5% and 0.45 Normal Saline infusing at a rate of 125 cc/hr. Which of the following should be done to assist with this patient's seizure activity?

administer Cerebyx as prescribed Even though intravenous Ativan or Valium are effective in stopping the seizure 65-80% of the time, Cerebyx can be delivered faster, will not cause cardiac depression like Dilantin, and is compatible with dextrose intravenous solutions

When an object is placed in the hand of a patient with neurologic impairment during assessment, the patient is unable to recognize the placement. This is termed tactile

agnosia. Tactile agnosia, or astereognosis, is a perceptual disorder in which a patient is unable to recognize by touch alone an object that has been placed in his or her hand.

The nurse identifies a nursing diagnosis of ineffective breathing pattern related to loss of central nervous system (CNS) integrative function for a patient who has posttraumatic brain swelling, based on the finding of

apneustic breathing. Apneustic breathing is caused by loss of CNS integration in the pons and is not effective in maximizing gas exchange

To provide appropriate instructions to a client who has an ear wick inserted to facilitate medication administration for external otitis, the nurse would advise the client to

apply ear drops directly to the wick.

The nurse identifies the nursing diagnosis of impaired verbal communication for a patient with expressive aphasia. An appropriate nursing intervention to help the patient communicate is to

ask simple questions that the patient can answer with "yes" or "no."

A patient is admitted to the hospital with dysphasia and right-sided weakness that resolves in a few hours. The nurse will anticipate teaching the patient about

aspirin (Ecotrin). Following a TIA, patients typically are started on medications such as aspirin to inhibit platelet function and decrease stroke risk

The nurse witnesses a patient with a seizure disorder as the patient suddenly jerks the arms and legs, falls to the floor, and regains consciousness immediately. It will be most important for the nurse to

assess the patient for a possible head injury.

The nurse would assess the client with a history of TIAs for

ataxia and dysarthria. Manifestations of a TIA in the vertebrobasilar circulation include two or more of the following: vertigo, diplopia, dysphagia, dysarthria, and ataxia.

A patient being admitted to the hospital for a laparoscopic procedure tells the nurse about a history of glaucoma and the need to continue using prescribed eyedrops while hospitalized. For this patient, the nurse should question the preoperative order of

atropine sulfate 0.4 mg administered intramuscularly on call to the operating room (OR). Atropine is a parasympathetic blocker and will relax the iris, causing blockage of aqueous humor outflow and an increase in intraocular pressure.

A patient with chronic otitis media is scheduled for a tympanoplasty. Preoperatively the nurse teaches the patient that postoperative expectations include

avoidance of coughing or blowing the nose. Coughing or blowing the nose increases pressure in the eustachian tube and middle ear cavity and disrupts postoperative healing. There is no postoperative need for prolonged bed rest, elevation of the head, or continuous antibiotic irrigation

The nurse clarifies that a generalized seizure, unlike a partial seizure, involves

both hemispheres. A generalized seizure involves both hemispheres

The clinical manifestations of Cushing's triad are

bradycardia, systolic hypertension, and widening pulse pressure.

The nurse gives diazepam to a client in status epilepticus to stop the seizure because prolonged seizure activity can cause

brain injury. Prolonged seizure activity exhausts the body's supply of oxygen and glucose and can result in brain injury.

When assessing motor function, which of the following are correct? Select all that apply. a. The presence of a Babinski reflex is a normal finding in the adult. b. Lower extremity muscle tone is assessed by asking the patient to push or pull his foot against resistance. c. When using noxious stimuli to elicit a motor response, each limb is tested separately. d. Abnormal extension, or decerebrate posturing, indicates a less positive outcome than abnormal flexion. e. Evaluation of deep tendon reflexes (DTR) is an essential part of the nursing assessment.

c, d Rationale: The presence of a Babinski response in the adult is indicative of neurologic dysfunction; pushing or pulling against resistance tests muscle strength; DTR are not routinely checked by the critical care nurse during assessment

A nurse at the eye clinic advises all patients to wear sunglasses that protect the eyes from ultraviolet light because ultraviolet sunlight exposure is associated with the development of

cataracts

For consciousness to occur, there needs to be communication between the

cerebral cortex and reticular activation system.

The nurse should observe a client with bacterial meningitis for

changes in sensorium. Other general manifestations related to infection are also present, such as fever, tachycardia, headache, prostration, chills, fever, nausea, and vomiting. The client may be irritable at first, but as the infection progresses, the sensorium often becomes clouded, and coma may develop

The nurse notes that a patient with a head injury has a clear nasal drainage. The most appropriate nursing action for this finding is to

check the nasal drainage for glucose with a Dextrostik or Testape.

When a client who underwent vestibular surgery complains of thirst, the nurse would avoid offering this client

cola. The client should avoid caffeine, which is a vestibular stimulant.

A score of 6 on the Glasgow Coma Scale (GCS) indicates

coma. Possible scores on the GCS range from 3 to 15. A score of 7 or less indicates coma

A patient found in a tonic-clonic seizure reports afterward that the seizure was preceded by numbness and tingling of the arm. The nurse knows that this finding indicates a(n) _____ seizure

complex partial The initial symptoms of a complex partial seizure involve clinical manifestations that are localized to a particular part of the body or brain

When doing an ophthalmologic examination the nurse practitioner assesses papilledema, which the practitioner recognizes as an indication of:

compression of the second cranial nerve. Papilledema, the swelling of the optic disc, occurs when there is increased intracranial pressure. The optic nerve, cranial nerve II, is compressed as well as intracerebral vessels. The most probable cause of the pressure is brain tumor.

During the neurologic assessment, the patient cooperates with the nurse's directions to grip with the hands and to move the feet but does not respond to the nurse's questions. The nurse will suspect

damage to the frontal lobe. Expressive speech is controlled by Broca's area in the frontal lobe

When the nurse applies a painful stimulus to the nailbeds of an unconscious patient, the patient responds with internal rotation, adduction, and flexion of the arms. The nurse documents this as

decorticate posturing. Internal rotation, adduction, and flexion of the arms in an unconscious patient is documented as decorticate posturing. Extension of the arms and legs is decerebrate posturing.

The nurse encourages a stroke victim by telling them that following a cerebrovascular accident (CVA) caused by thrombosis, the client's condition may improve after several days as a result of

decrease of edema in the area. The area of edema after ischemia may lead to temporary neurologic deficits. Edema may subside in a few hours or sometimes in several days, and the client may regain some function.

The nurse would explain that a nonsurgical approach to reduce the clinical manifestations of labyrinthitis is injection of an ototoxic drug into the middle ear to

destroy hair cells. The ototoxic drug destroys hair cells in the middle ear, which will reduce the manifestations of vertigo.

A patient with increased intracranial pressure is prescribed mannitol for the management of the increased pressure. The nurse realizes that this medication will

draw fluid from the edematous cerebral tissue into the vascular space.

The nurse, caring for a patient with neurological symptoms, should assess the patient for which of the following cluster of symptoms?

dysphagia, hemianopsia, hemiparesis

The nurse will hyperoxygenate a comatose client before suctioning the airway to decrease the risk of

dysrhythmias.

A patient who has bacterial meningitis and is disoriented and anxious has a nursing diagnosis of disturbed sensory perception related to decreased level of consciousness. An appropriate nursing intervention is to

encourage family members to remain at the bedside. Patients with meningitis and disorientation will be calmed by the presence of someone familiar at the bedside

The nurse obtaining the history of a client admitted for retinal detachment would note that the assessment finding not consistent with retinal detachment is the client's report of

experiencing intense pain. No pain is associated with detachment of the retina.

A patient arrives in the emergency department complaining of eye itching and pain caused by sleeping with contact lenses in place. To facilitate further examination of the eye, the nurse will anticipate the need for

fluorescein dye. Eye itching and pain suggest a possible corneal abrasion or ulcer, which can be visualized using fluorescein dye

A patient with seizure activity is receiving intravenous Dilantin. Which of the following should the nurse do when caring for this patient?

frequent monitoring of the injection site : Nursing care for a patient with an acute onset of seizures in the acute care setting includes observing the injection site frequently during administration of Phenytoin to prevent infiltration

The assessment the nurse documents that supports the finding of apraxia would be the client's inability to

get dressed independently. In apraxia the client cannot carry out a skilled act such as dressing in the absence of paralysis.

The nurse providing instructions to a client after ear surgery would tell the client that for the next 4 to 6 weeks, he/she should avoid

getting the ear wet. Keep the ear dry for 4 to 6 weeks after ear surgery. Avoid physical activity for 1 week and exercises or sports for 3 weeks. Blow the nose gently one side at a time and sneeze or cough with the mouth open for 1 week after surgery. Avoid airplane flights for the first week after surgery

A client with stroke has a nursing diagnosis of Impaired Verbal Communication and has specific difficulty in verbal expression. The most helpful strategy by the nurse would be to

give the client practice in repeating words after the nurse.

To assess the functioning of the optic nerve (CN II), the nurse should

have the patient read a magazine. The optic nerve is responsible for visual fields and visual acuity.

An 87-year-old patient has marked bilateral presbycusis. In performing a Rinne test on the patient, the nurse would anticipate that the patient

hears best when the tuning fork is placed next to the ear canal. The Rinne test is positive when air conduction is heard longer than bone conduction when a tuning fork is held against the mastoid bone (bone conduction) and then next to the ear canal (air conduction).

When the nurse caring for a client using an ICP monitor reads ICP as 20 mm Hg, the nurse would interpret this as

higher than normal.

A patient has a systemic blood pressure (BP) of 120/60 mm Hg and an intracranial pressure of 24 mm Hg. The nurse determines that the cerebral perfusion pressure (CPP) of this patient indicates

impaired brain blood flow. The patient's CPP is 56, below the normal of 70 to 100 mm Hg and approaching the level of ischemia and neuronal death

A patient with cerebral infarction is experiencing an acceleration of symptoms. The nurse realizes that the death of the cerebral tissue is to due to which of the following?

increased concentration of sodium, chloride, and calcium in the brain cells

The most appropriate action that the nurse working at a camp would take to remove an insect from a camper's ear is

instill a few drops of mineral oil into the ear. For removal of a live insect, the ear canal is filled with mineral oil, lidocaine, or an ether-soaked cotton ball, not water, to kill or stupefy the insect. Water will cause the insect to swell, making it harder to remove.

In planning the care of a client with Crohn's disease for 10 years who has developed Sjögren's syndrome, the nurse would include

instilling lubricating eye drops frequently. Sjögren's syndrome is a condition is which tear secretion is reduced and is associated with several systemic disorders, including Crohn's disease. Frequent instillation of lubricating eye drops or ointment is effective in most cases. The other options are not treatments for this condition.

A nurse preparing to give mouth care to a comatose client should first place this client into the position of

lateral. When performing mouth care, place a comatose client in a lateral position to prevent aspiration.

A priority nursing intervention for a client in the emergency department with a suspected spinal cord injury is to

logroll the client. To prevent further injury to the client with a suspected spinal cord injury, the nurse (and other members of the health care team) should logroll the client. Mannitol is used for increased intracranial pressure. A tetanus booster may or may not be indicated, depending on if any skin was broken. While a thorough history is important, client safety is paramount.

The nurse caring for a client with a conductive hearing loss would enhance communication by facing the client and

lowering the pitch of the voice. Conduction hearing loss occurs in the higher frequencies. Loud, slow, or exaggerated movements may confuse the client.

During the admission assessment, the patient's spouse tells the nurse that the patient has functional blindness and that the spouse has cared for the patient for many years. During the initial assessment of the patient, it is most important for the nurse to

make eye contact with the patient and ask about any need for assistance. Making eye contact with a partially sighted patient allows the patient to hear the nurse more easily and allows the nurse to assess the patient's facial expressions

The nurse would instruct a client being taught to administer pilocarpine eye drops for glaucoma that the client

may have some blurring of vision after the drops are instilled.

The nurse would counsel clients who have experienced optic neuritis that they should see a physician regularly because they are at high risk for

multiple sclerosis. There is a close association between optic neuritis and multiple sclerosis.

The nursing action contraindicated in the care of a client with a severe basilar skull fracture is

nasal suctioning. Never suction the nasal passages in the client with a basilar skull fracture or facial fractures because the suction catheter can enter the cranial cavity.

The classic manifestations of meningitis are

nuchal rigidity (rigidity of the neck), Brudzinski's sign and Kernig's sign, and photophobia.

The nurse expects that management of the patient who experiences a brief episode of tinnitus, diplopia, and dysarthria with no residual effects will include

oral administration of ticlopidine (Ticlid). The patient's symptoms are consistent with transient ischemic attack (TIA), and drugs that inhibit platelet aggregation are prescribed after a TIA to prevent stroke.

When the client experiences convulsive movement beginning in the hand and progressing to the arm and face, the nurse recognizes this as being consistent with

partial seizure with motor signs. The observation of the "jacksonian march" identifies this seizure activity as a partial seizure with motor signs

A young client has a perforation of the tympanic membrane that occurred while cleaning the ear with a pointed object. The nurse would advise that

perforations often heal spontaneously with no complications.

In reviewing a 50-year-old patient's medical record, the nurse notes that the last eye examination revealed an intraocular pressure of 28 mm Hg. The nurse will plan to assess

peripheral vision. The patient's increased intraocular pressure indicates glaucoma, which decreases peripheral vision

A patient with homonymous hemianopsia resulting from a stroke has a nursing diagnosis of disturbed sensory perception related to hemianopsia. To help the patient learn to compensate for the deficit during the rehabilitation period, the nurse should

place objects necessary for activities of daily living on the patient's affected side. During the rehabilitation period, placing objects on the affected side will encourage the patient to use the scanning technique to visualize the affected side

A victim of an automobile accident was found unconscious at the scene of the accident but briefly regained consciousness during transport to the hospital. On admission, the Glasgow Coma Scale score is 8, and an acute epidural hematoma is suspected. The nurse will anticipate the need to

prepare the patient for immediate craniotomy. The principal treatment for epidural hematoma is rapid surgery to remove the hematoma and prevent herniation

A patient with a brain tumor is receiving radiation after having had a craniotomy. The nurse will explain that the purpose of the ordered methylprednisolone (Solu-Medrol) is to

prevent an increase in intracranial pressure (ICP). Radiation can lead to cerebral edema and rapid ICP increases and corticosteroids are administered to prevent this

The nurse is observing a student who is preparing to perform an ear examination of a 24-year-old patient. The nurse will need to intervene if the student

pulls the auricle of the ear down and backward. The auricle should be pulled up and back when assessing an adult.

The nurse assesses agnosia in a client who had a CVA. An example of this disturbance would be an inability to

recognize eating utensils. Agnosia is a disturbance in the ability to recognize familiar objects through the senses. The most common types are visual and auditory. A client with visual agnosia may examine objects curiously but be unable to determine their function.

When the spouse of a client who has had a CVA as a result of a cerebral hemorrhage asks the nurse about the client's chances for recovery, the nurse should base a reply on knowledge that with this type of CVA

recovery is slow and less complete. Hemorrhagic strokes usually produce extensive residual function loss and have the slowest recovery of all types of stroke.

When caring for a patient with a right-sided intracerebral hemorrhage, the nurse suspects possible supratentorial herniation and compression of the brainstem when the

right pupil does not react to light. A dilated pupil on the ipsilateral side in a patient with an acute brain injury indicates herniation

A patient has a stroke affecting the right hemisphere of the brain. Based on knowledge of the effects of right brain damage, the nurse establishes a nursing diagnosis of

risk for injury related to denial of deficits and impulsiveness. : Right-sided brain damage typically causes denial of any deficits and poor impulse control, leading to risk for injury when the patient attempts activities such as transferring from a bed to a chair. Right-sided brain damage causes left hemiplegia. Left-sided brain damage typically causes language deficits. Left-sided brain damage is associated with depression and distress about the disability

During the nursing history, a patient complains of dizziness when bending over and of nausea and dizziness associated with physical activities. The nurse will plan to teach the patient about

rotary chair testing. The patient's clinical manifestations of dizziness and nausea suggest a disorder of the labyrinth, which controls balance and contains three semicircular canals and the vestibule. Rotary chair testing is used to test vestibular function

The nurse is concerned about a client's slowly healing corneal ulcer because such an injury can lead to

secondary glaucoma Slowly healing corneal injuries may lead to secondary glaucoma.

A client is being worked up for a possible brain tumor. An important intervention the nurse would include in the nursing care plan specific to this client is

seizure precautions.

The nurse assessing a client with an inner ear disorder would be aware that the presenting clinical manifestation will be

sensorineural hearing loss.

The nurse would consider that discharge teaching for a client after cataract surgery was not effective when the client states "I will

sleep on the side they operated on." The postsurgical cataract client should wear eye shields, avoid lifting more than 5 pounds until cleared by the ophthalmologist, and should only experience mild pain, for which acetaminophen (Tylenol) should be effective. These clients should avoid sleeping on the operated side.

To evaluate a client's balance using Romberg's test, the nurse would

stand the client with feet together, eyes closed, and arms to the side. The inner ear is assessed for balance by performing Romberg's test.

A critically injured patient can be aroused only by vigorous and continuous external stimuli. The patient's level of consciousness is considered

stuporous. The patient is stuporous when arousal is possible only in response to vigorous and continuous external stimuli

The ability to access CSF by a lumbar puncture is attributable to the flow of CSF in the

subarachnoid space.

The emergency department nurse should position the client with cranial injuries

supine with head of bed elevated 30 degrees Place the client with cranial injures supine with the head elevated 30 degrees unless contraindicated (e.g., some spinal injuries, some aneurysms).

The nurse points out the important difference between metabolically induced coma and structurally induced coma is that metabolically induced coma results in

symmetrical motor manifestations. Coma caused by a metabolic disorder more often is manifested as the presence of bilateral or symmetrical findings because the disorder affects the entire brain rather than just one section.

The family of a patient with a concussion is concerned that the patient continues to complain of and demonstrate ongoing neurological deficits. Which of the following should the nurse explain to the family?

symptoms of a concussion can last up to 3 months

The nursing action that would be appropriate in caring for a client who has experienced stroke because of hemorrhage is to

teach the client to avoid the Valsalva maneuver.

The region of the brain that acts as a relay station for both motor and sensory activity is the

thalamus.

As part of preoperative counseling for the client contemplating cataract surgery, the nurse would explain that postoperative follow-up is done

the day after, 1 week after, and 1 month after surgery.

A patient has bilateral senile cataracts and is scheduled for a right cataract extraction and intraocular lens implantation at an ambulatory surgical center. During the preoperative assessment of the patient, it is most important for the nurse to assess

the visual acuity of the patient's left eye. Because it can take up to several weeks before the maximum improvement in vision occurs in the right eye, patient safety and independence are determined by the vision in the left eye.

A client has a history of experiencing focal neurologic deficits, such as slurred speech and facial weakness, that last for a few hours at a time. The nurse then assesses this client for other possible manifestations of

transient ischemic attacks (TIAs). TIAs are focal neurologic deficits lasting less than 24 hours that produce manifestations of slurred speech, facial weakness, and ataxia.

A patient is recovering from surgery to clip an aneurysm. Which of the following interventions will prevent cerebral vasospasm in this patient?

triple H therapy Vasospasm decreases perfusion to brain tissue and is prevented and treated with "triple H therapy": hypervolemia, hypertension, and hemodilution

Safety precautions the nurse instructs the client with homonymous hemianopsia to use include

turning the head to scan the visual field. Clients with homonymous hemianopsia cannot see past the midline without turning the head toward that side. This can create a safety concern for the client. The client may run into objects, trip, or fall.

A nurse could appropriately assess for the doll's eye reflex in a client who is a/an

unconscious teenager who has overdosed on drugs.

When performing a focused assessment on a patient with a lesion of the left posterior temporal lobe, the nurse will assess for

understanding of written and oral language. The posterior temporal lobe integrates the visual and auditory input for language comprehension

The nurse caring for a client receiving phenytoin (Dilantin) should assess for

unsteady gait, slurred speech, and blurred vision. Serious adverse outcomes of antiseizure medications are unsteady gait, slurred speech, extreme fatigue, blurred vision, or feelings of suicide.

A patient is seen in the ophthalmology clinic and diagnosed with recurrent staphylococcal and seborrheic blepharitis. The nurse will plan to teach the patient about

using baby shampoo to clean the lids. Baby shampoo is used to soften and remove crusts associated with blepharitis

Transcranial Doppler studies are used in the patient following rupture of a cerebral aneurysm to assess for

vasospasm

The critical care nurse explains to the family of a client who is to receive nimodipine following hemorrhagic stroke that the purpose of this drug is to treat

vasospasm. Nimodipine, a calcium-channel blocker, is used to treat vasospasm secondary to subarachnoid hemorrhage.

The nurse on the medical unit receives a verbal report from the emergency department nurse that a patient has an occlusion of the left posterior cerebral artery. When admitting the patient to the medical floor, the nurse will anticipate that the patient may have

visual deficits. Visual disturbances are expected with posterior cerebral artery occlusion

To determine whether treatment is effective for a patient with primary open-angle glaucoma (POAG), the nurse will evaluate the patient for improvement in

visual field. POAG develops slowly and without symptoms except for a gradual loss of visual field. Acute closed-angle glaucoma may present with excruciating pain, colored halos, and blurred vision

To assess motor response, the nurse performing a neurologic assessment on a client in a coma would ask the client to

wiggle the toes. Motor responses are assessed by asking the client to follow specific commands, such as "wiggle your toes." Do not ask the client to squeeze your hand because grasp is a reflexive response that occurs in clients with head injury.

Neurologic testing of the patient by the nurse indicates impaired functioning of the left glossopharyngeal nerve (CN IX) and the vagus nerve (CN X). Based on these findings, the nurse plans to

withhold oral fluid or foods. The glossopharyngeal and vagus nerves innervate the pharynx and control the gag reflex; a patient with impaired function of these nerves is at risk for aspiration.

A patient who has heart failure and has been receiving large doses of IV furosemide (Lasix) tells the nurse, "I cannot hear very well. My ears are ringing." The most appropriate action by the nurse is to

withhold the ordered dose of furosemide and notify the health care provider. Because ototoxicity associated with use of furosemide can lead to deafness and tinnitus, the most appropriate action at this time is to hold the furosemide until checking with the health care provider
