Nrs 111 Chronic Neuro- NCLEX Questions

The wife of a man with moderate AD has a nursing diagnosis of social isolation related to diminishing social relationships and behavioral problems of the patient with AD. What is a nursing intervention that would be appropriate to provide respite care and allow the wife to have satisfactory contact with significant others? a. Help the wife to arrange for adult day care for the patient. b. Encourage permanent placement of the patient in the Alzheimer's unit of a long-term care facility. c. Refer the wife to a home health agency to arrange daily home nursing visits to assist with the patient's care. d. Arrange for hospitalization of the patient for 3 or 4 days so that the wife can visit out-of-town friends and relatives.

A Adult day care is an option to provide respite for caregivers and a protective environment for the patient during the early and middle stages of AD. There are also in-home respite care providers. The respite from the demands of care allows the caregiver to maintain social contacts, perform normal tasks of living, and be more responsive to the patient's needs. Visits by home health nurses involve the caregiver and cannot provide adequate respite. Institutional placement is not always an acceptable option at earlier stages of AD, nor is hospitalization available for respite care.

A patient with Alzheimer's disease (AD) dementia has manifestations of depression. The nurse knows that treatment of the patient with antidepressants will most likely do what? a. Improve cognitive function b. Not alter the course of either condition c. Cause interactions with the drugs used to treat the dementia d. Be contraindicated because of the central nervous system (CNS)-depressant effect of antidepressants

A Depression is often associated with AD, especially early in the disease when the patient has awareness of the diagnosis and the progression of the disease. When dementia and depression occur together, intellectual deterioration may be more extreme. Depression is treatable and use of antidepressants often improves cognitive function.

To encourage adequate nutritional intake for a female client with Alzheimer's disease, the nurse should: A. Stay with the client and encourage him to eat. B. Help the client fill out his menu. C. Give the client privacy during meals. D. Fill out the menu for the client.

A Staying with the client and encouraging him to feed himself will ensure adequate food intake. A client with Alzheimer's disease can forget how to eat. Allowing privacy during meals, filling out the menu, or helping the client to complete the menu doesn't ensure adequate nutritional intake.

The RN in charge at a long-term care facility could delegate which activities to unlicensed assistive personnel (UAP) (select all that apply)? a. Assist the patient with eating. b. Provide personal hygiene and skin care. c. Check the environment for safety hazards. d. Assist the patient to the bathroom at regular intervals. e. Monitor for skin breakdown and swallowing difficulties.

A, B, D. All caregivers are responsible for the patient's safety. Basic care activities, such as those associated with personal hygiene and activities of daily living (ADLs) can be delegated to unlicensed assistive personnel (UAP). The RN will perform ongoing assessments and develop and revise the plan of care as needed. The RN will assess the patient's safety risk factors, provide education, and make referrals. The licensed practical nurse (LPN) could check the patient's environment for potential safety hazards.

The sister of a patient with AD asks the nurse whether prevention of the disease is possible. In responding, the nurse explains that there is no known way to prevent AD but there are ways to keep the brain healthy. What is included in the ways to keep the brain healthy (select all that apply)? a. Avoid trauma to the brain. b. Recognize and treat depression early. c. Avoid social gatherings to avoid infections. d. Do not overtax the brain by trying to learn new skills. e. Daily wine intake will increase circulation to the brain. f. Exercise regularly to decrease the risk for cognitive decline

A, B, F. The sister of a patient with AD asks the nurse whether prevention of the disease is possible. In responding, the nurse explains that there is no known way to prevent AD but there are ways to keep the brain healthy. What is included in the ways to keep the brain healthy (select all that apply)? a. Avoid trauma to the brain. b. Recognize and treat depression early. c. Avoid social gatherings to avoid infections. d. Do not overtax the brain by trying to learn new skills. e. Daily wine intake will increase circulation to the brain. f. Exercise regularly to decrease the risk for cognitive decline

What manifestations of cognitive impairment are primarily characteristic of delirium (select all that apply)? a. Reduced awareness b. Impaired judgments c. Words difficult to find d. Sleep/wake cycle reversed e. Distorted thinking and perception f. Insidious onset with prolonged duration

A, D, E. Manifestations of delirium include cognitive impairment with reduced awareness, reversed sleep/wake cycle, and distorted thinking and perception. The other options are characteristic of dementia.

The son of a patient with early-onset AD asks if he will get AD. What should the nurse tell this man about the genetics of AD? a. The risk of early-onset AD for the children of parents with it is about 50%. b. Women get AD more often than men do, so his chances of getting AD are slim. c. The blood test for the ApoE gene to identify this type of AD can predict who will develop it. d. This type of AD is not as complex as regular AD, so he does not need to worry about getting AD.

A. The risk of early-onset AD for the children of parents with it is 50%. Women do get AD more often than men but that is more likely related to women living longer than men than to the type of AD. ApoE gene testing is used for research with late-onset AD but does not predict who will develop the disease. Late-onset AD is more genetically complex than early-onset AD and is more common in those over age 60 but because his parent has early-onset AD he is at a 50% risk of getting it.

A patient with moderate AD has a nursing diagnosis of impaired memory related to effects of dementia. What is an appropriate nursing intervention for this patient? a. Post clocks and calendars in the patient's environment. b. Establish and consistently follow a daily schedule with the patient. c. Monitor the patient's activities to maintain a safe patient environment. d. Stimulate thought processes by asking the patient questions about recent activities

B Adhering to a regular, consistent daily schedule helps the patient to avoid confusion and anxiety and is important both during hospitalization and at home. Clocks and calendars may be useful in early AD but they have little meaning to a patient as the disease progresses. Questioning the patient about activities and events they cannot remember is threatening and may cause severe anxiety. Maintaining a safe environment for the patient is important but does not change the disturbed thought processes.

What is one focus of collaborative care of patients with AD? a. Replacement of deficient acetylcholine in the brain b. Drug therapy for cognitive problems and undesirable behaviors c. The use of memory-enhancing techniques to delay disease progression d. Prevention of other chronic diseases that hasten the progression of AD

B Because there is no cure for AD, collaborative management is aimed at controlling the decline in cognition, controlling the undesirable manifestations that the patient may exhibit, and providing support for the family caregiver. Anticholinesterase agents help to increase acetylcholine (ACh) in the brain but a variety of other drugs are also used to control behavior. Memory enhancing techniques have little or no effect in patients with AD, especially as the disease progresses. Patients with AD have limited ability to communicate health symptoms and problems, leading to a lack of professional attention for acute and other chronic illnesses

82-year-old Mr. Robeson together with his daughter arrived to the medical-surgical unit for diagnostic confirmation and management of probable delirium. Which statement by the client's daughter best supports the diagnosis? A. "Maybe it's just caused by aging. This usually happens by age 82." B. "The changes in his behavior came on so quickly! I wasn't sure what was happening." C. "Dad just didn't seem to know what he was doing. He would forget what he had for breakfast." D. "Dad has always been so independent. He's lived alone for years since mom died."

B Delirium is an acute process characterized by abrupt, spontaneous cognitive dysfunction. Cognitive impairment disorders (dementia or delirium) are not normal consequences of aging. Option C would be characteristic of someone with dementia. Although option D provides background data about the client, it is unrelated to the current problem of delirium.

The family caregiver for a patient with AD expresses an inability to make decisions, concentrate, or sleep. The nurse determines what about the caregiver? a. The caregiver is also developing signs of AD. b. The caregiver is manifesting symptoms of caregiver role strain. c. The caregiver needs a period of respite from care of the patient. d. The caregiver should ask other family members to participate in the patient's care.

B Family caregiver role strain is characterized by such symptoms of stress as the inability to sleep, make decisions, or concentrate. It is frequently seen in family members who are responsible for the care of the patient with AD. Assessment of the caregiver may reveal a need for assistance to increase coping skills, effectively use community resources, or maintain social relationships. Eventually the demands on a caregiver exceed the resources and the person with AD may be placed in an institutional setting.

A patient with AD in a long-term care facility is wandering the halls very agitated, asking for her "mommy" and crying. What is the best response by the nurse? a. Ask the patient, "Why are you behaving this way?" b. Tell the patient, "Let's go get a snack in the kitchen." c. Ask the patient, "Wouldn't you like to lie down now?" d. Tell the patient, "Just take some deep breaths and calm down."

B Patients with moderate to severe AD frequently become agitated but because their short-term memory loss is so pronounced, distraction is a very good way to calm them. "Why" questions are upsetting to them because they don't know the answer and they cannot respond to normal relaxation techniques.

The earliest symptom associated with Alzheimer's disease is which of the following? A. Hallucinations B. Short-term memory impairment C. Behavioral disinhibition D. Apraxia

B Short-term memory impairment Rationale: In Alzheimer's disease, the impaired ability to acquire and remember new information (short-term memory) occurs before loss of memory for events in the distant past (long-term memory). Hallucinations are rarely seen as symptoms of Alzheimer's. They are much more common with delirium and may be seen in dementia with Lewy bodies and Parkinsonian dementia. Behavioral disinhibition is more often seen as an earlier symptom in frontotemporal types of dementia such as Pick's disease. Behavioral disinhibition or apraxia usually are seen in someone in the later stages of Alzheimer's disease.

The wife of a patient who is manifesting deterioration in memory asks the nurse whether her husband has AD. The nurse explains that a diagnosis of AD is usually made when what happens? a. A urine test indicates elevated levels of isoprostanes b. All other possible causes of dementia have been eliminated c. Blood analysis reveals increased amounts of β-amyloid protein d. A computed tomography (CT) scan of the brain indicates brain atrophy

B The only definitive diagnosis of AD can be made on examination of brain tissue during an autopsy but a clinical diagnosis is made when all other possible causes of dementia have been eliminated. Patients with AD may have β-amyloid proteins in the blood, brain atrophy, or isoprostanes in the urine but these findings are not exclusive to those with AD.

The health care provider is trying to differentiate the diagnosis of the patient between dementia and dementia with Lewy bodies (DLB). What observations by the nurse support a diagnosis of DLB (select all that apply)? a. Tremors b. Fluctuating cognitive ability c. Disturbed behavior, sleep, and personality d. Symptoms of pneumonia, including congested lung sounds e. Bradykinesia, rigidity, and postural instability without tremor

B, E. Dementia with Lewy bodies (DLB) is diagnosed with dementia plus two of the following symptoms: (1) extrapyramidal signs such as bradykinesia, rigidity, and postural instability but not always a tremor, (2) fluctuating cognitive ability, and (3) hallucinations. The extra pyramidal signs plus tremors would more likely indicate Parkinson's disease. Disturbed behavior, sleep, personality, and eventually memory are characteristics of frontotemporal lobe degeneration (FTLD).

What should be included in the management of a patient with delirium? a. The use of restraints to protect the patient from injury b. The use of short-acting benzodiazepines to sedate the patient c. Identification and treatment of underlying causes when possible d. Administration of high doses of an antipsychotic drug such as haloperidol (Haldol)

C Care of the patient with delirium is focused on identifying and eliminating precipitating factors if possible. Treatment of underlying medical conditions, changing environmental conditions, and discontinuing medications that induce delirium are important. Drug therapy is reserved for those patients with severe agitation because the drugs themselves may worsen delirium.

During assessment of a patient with dementia, the nurse determines that the condition is potentially reversible when finding out what about the patient? a. Has long-standing abuse of alcohol b. Has a history of Parkinson's disease c. Recently developed symptoms of hypothyroidism d. Was infected with human immunodeficiency virus (HIV) 10 years ago

C Hypothyroidism can cause dementia but it is a treatable condition if it has not been long standing. The other conditions are causes of irreversible dementia.

The newly admitted patient has moderate AD. What does the nurse know this patient will need help with? a. Eating b. Walking c. Dressing d. Self-care activities

C In the moderate stage of AD, the patient may need help with getting dressed. In the severe stage, patients will be unable to dress or feed themselves and are usually incontinent.

Which of the following statements is accurate pertaining to frontotemporal dementia? Frontotemporal dementia: A. Includes Lewy bodies, and is diagnosed on the basis of personality changes. B. Is an abrupt onset dementia with abnormal reflexes and emotional instability. C. Includes Pick's disease, and is diagnosed on the basis of personality changes and the presence of frontal brain atrophy. D. Includes both Lewy and Pick's bodies inside nerve cells, and behavioral disinhibition.

C Includes Pick's disease, and is diagnosed on the basis of personality changes and the presence of frontal brain atrophy. Rationale: Frontotemporal dementia, which includes Pick's disease, is diagnosed on the basis of personality changes and presence of frontal brain atrophy. Pick's disease is characterized by two specific neuropathological findings on autopsy: (1) Pick's bodies inside nerve cells, and (2) ballooned nerve cells. Lewy bodies are found in Dementia with Lewy Bodies (DMB) and Parkinson's Disease (PD).

For what purpose would the nurse use the Mini-Mental State Examination to evaluate a patient with cognitive impairment? a. It is a good tool to determine the etiology of dementia. b. It is a good tool to evaluate mood and thought processes. c. It can help to document the degree of cognitive impairment in delirium and dementia. d. It is useful for initial evaluation of mental status but additional tools are needed to evaluate changes in cognition over time.

C The Mini-Mental State Examination is a tool to document the degree of cognitive impairment and it can be used to determine a baseline from which changes over time can be evaluated. It does not evaluate mood or thought processes but can detect dementia and delirium and differentiate these from psychiatric mental illness. It cannot help to determine etiology.

80-year-old Mr. Stevens is accompanied to the clinic by his son, who tells the nurse that the client's constant confusion, incontinence, and tendency to wander are intolerable. The client was diagnosed with chronic cognitive impairment disorder. Which nursing diagnosis is most appropriate for the client's son? A. Risk for other-directed violence B. Disturbed sleep pattern C. Caregiver role strain D. Social isolation

C The son's description exemplifies some of the problems commonly encountered by a primary caregiver who is caring for someone with a cognitive impairment disorder. Although the other nursing diagnoses are possibilities, the scenarios does not provide enough information to validate any of these.

Mrs. Mendoza is a 75-year-old client who has dementia of the Alzheimer's type and confabulates. The nurse understands that this client: A. denies confusion by being jovial. B. pretends to be someone else. C. rationalizes various behaviors. D. fills in memory gaps with fantasy.

D Confabulation is a communication device used by patients with dementia to compensate for memory gaps. The remaining answer choices are incorrect.

A 68-year-old man is admitted to the emergency department with multiple blunt trauma following a one-vehicle car accident. He is restless; disoriented to person, place, and time; and agitated. He resists attempts at examination and calls out the name "Janice." Why should the nurse suspect delirium rather than dementia in this patient? a. The fact that he wouldn't have been allowed to drive if he had dementia b. His hyperactive behavior, which differentiates his condition from the hypoactive behavior of dementia c. The report of emergency personnel that he was noncommunicative when they arrived at the accident scene d. The report of his family that although he has heart disease and is "very hard of hearing," this behavior is unlike him

D Delirium is an acute problem that usually has a rapid onset in response to a precipitating event, especially when the patient has underlying health problems, such as heart disease and sensory limitations. In the absence of prior cognitive impairment, a sudden onset of confusion, disorientation, and agitation is usually delirium. Delirium may manifest with both hypoactive and hyperactive symptoms.

The husband of a patient is complaining that his wife's memory has been decreasing lately. When asked for examples of her memory loss, the husband says that she is forgetting the neighbors' names and forgot their granddaughter's birthday. What kind of loss does the nurse recognize this to be? a. Delirium b. Memory loss in AD c. Normal forgetfulness d. Memory loss in mild cognitive impairment

D In mild cognitive impairment people frequently forget people's names and begin to forget important events. Delirium changes usually occur abruptly. In Alzheimer's disease the patient may not remember knowing a person and loses the sense of time and which day it is. Normal forgetfulness includes momentarily forgetting names and occasionally forgetting to run an errand.

A family member expresses concern to a nurse about behavioral changes in an elderly aunt. Which would cause the nurse to suspect a cognitive impairment disorder? A. Decreased interest in activities that she once enjoyed B. Fearfulness of being alone at night C. Increased complaints of physical ailments D. Problems with preparing a meal or balancing her checkbook

D Making a meal and balancing a checkbook are higher level cognitive functions that, when unable to be performed, may signal onset of a cognitive disorder. Although the remaining behaviors may occur, they are not associated only with cognitive impairment and may indicate depression or other problems.

Which patient is most at risk for developing delirium? a. A 50-year-old woman with cholecystitis b. A 19-year-old man with a fractured femur c. A 42-year-old woman having an elective hysterectomy d. A 78-year-old man admitted to the medical unit with complications related to heart failure

D Risk factors that can precipitate delirium include age of 65 years or older, male gender, and severe acute illness (e.g., heart failure). The 78-year-old man has the most risk factors for delirium (see Table 60-14).

Which statement accurately describes dementia? a. Overproduction of β-amyloid protein causes all dementias. b. Dementia resulting from neurodegenerative causes can be prevented. c. Dementia caused by hepatic or renal encephalopathy cannot be reversed. d. Vascular dementia can be diagnosed by brain lesions identified with neuroimaging

D The diagnosis of vascular dementia can be aided by neuroimaging studies showing vascular brain lesions along with exclusion of other causes of dementia. Overproduction of β-amyloid protein contributes to Alzheimer's disease (AD). Vascular dementia can be prevented or slowed by treating underlying diseases (e.g., diabetes mellitus, cardiovascular disease). Dementia caused by hepatic or renal encephalopathy potentially can be reversed

A student nurse was asked which of the following best describes dementia. Which of the following best describes the condition? A. Memory loss occurring as part of the natural consequence of aging B. Difficulty coping with physical and psychological change C. Severe cognitive impairment that occurs rapidly D. Loss of cognitive abilities, impairing ability to perform activities of daily living

D The impaired ability to perform self-care is an important measure of a client's dementia progression and loss of cognitive abilities. Difficulty or impaired ability to perform normal activities of daily living, such as maintaining hygiene and grooming, toileting, making meals, and maintaining a household, are significant indications of dementia. Slowing of processes necessary for information retrieval is a normal consequence of aging. However, the global statement that memory loss occurs as part of natural aging is not true. Dementia is not normal; it is a disease. Difficulty coping with changes can be experienced by any client, not just one with dementia. The rapid occurrence of cognitive impairment refers to delirium.

Problems with memory and learning would relate to which of the following lobes? A. Frontal B. Occipital C. Parietal D. Temporal

D The temporal lobe functions to regulate memory and learning problems because of the integration of the hippocampus. The frontal lobe primarily functions to regulate thinking, planning, and judgment. The occipital lobe functions regulate vision. The parietal lobe primarily functions with sensory function.

When caring for a patient in the severe stage of AD, what diversion or distraction activities would be appropriate? a. Watching TV b. Playing games c. Books to read d. Mobiles or dangling ribbons

D In the severe stage of AD, the patient is at a developmental level of 15 months or less; therefore appropriate distractions would be infant toys. Watching TV and playing games are more appropriate in the mild stage. Books to read would need to be at developmentally appropriate levels to be used as a diversion.

Which statement accurately describes dementia? a. Overproduction of β-amyloid protein causes all dementias. b. Dementia resulting from neurodegenerative causes can be prevented. c. Dementia caused by hepatic or renal encephalopathy cannot be reversed. d. Vascular dementia can be diagnosed by brain lesions identified with neuroimaging.

D The diagnosis of vascular dementia can be aided by neuroimaging studies showing vascular brain lesions along with exclusion of other causes of dementia. Overproduction of β-amyloid protein contributes to Alzheimer's disease (AD). Vascular dementia can be prevented or slowed by treating underlying diseases (e.g., diabetes mellitus, cardiovascular disease). Dementia caused by hepatic or renal encephalopathy potentially can be reversed.

The patient is receiving donepezil (Aricept), lorazepam (Ativan), risperidone (Risperdal), and sertraline (Zoloft) for the management of AD. What benzodiazepine medication is being used to help manage this patient's behavior? a. Sertraline (Zoloft) b. Donepezil (Aricept) c. Lorazepam (Ativan) d. Risperidone (Risperdal)

Lorazepam (Ativan) is a benzodiazepine used to manage behavior with AD. Sertraline (Zoloft) is a selective serotonin reuptake inhibitor used to treat depression. Donepzil (Aricept) is a cholinesterase inhibitor used for decreased memory and cognition. Risperidone (Risperdal) is an antipsychotic used for behavior management.
