Mental Health Nursing Chapter 23: Neurocognitive Disorders week 5

The nurse is caring for a patient admitted with a history of hypertension. The patient's medication history includes hydrochlorothiazide daily for the past 10 years. Which parameter would indicate the optimal intended effect of this drug therapy? A) Weight loss of 2 lb B) BP 128/86 mm Hg Correct C) Absence of ankle edema D) Output of 600 mL per 8 hours

B) Hydrochlorothiazide may be used alone as monotherapy to manage hypertension or in combination with other medications if not effective alone. After the first few weeks of therapy, the diuretic effect diminishes, but the antihypertensive effect remains. Because the patient has been taking this medication for 10 years, the most direct measurement of its intended effect would be the blood pressure.

When providing dietary instruction to a patient with hypertension, the nurse would advise the patient to restrict intake of which meat? A) Broiled fish b) Roasted duck C) Roasted turkey D) Baked chicken breast

B) Roasted duck is high in fat, which should be avoided by the patient with hypertension. Weight loss may slow the progress of atherosclerosis and overall cardiovascular disease risk. The other meats are lower in fat and are therefore acceptable in the diet.

In caring for a patient admitted with poorly controlled hypertension, which laboratory test result should the nurse understand as indicating the presence of target organ damage? a) Serum uric acid of 3.8 mg/dL b) Serum creatinine of 2.6 mg/dL c) Serum potassium of 3.5 mEq/L d0 Blood urea nitrogen of 15 mg/dL

b) The normal serum creatinine level is 0.6 to 1.3 mg/dL. This elevated level indicates target organ damage to the kidneys. The other laboratory results are within normal limits.

A patient with stage 3 Alzheimer's disease tires easily and prefers to stay home rather than attend social activities. The spouse does the grocery shopping because the patient cannot remember what to buy. Which nursing diagnosis applies at this time? a. Self-care deficit b. Impaired memory c. Caregiver role strain d. Adult failure to thrive

ANS: B Memory impairment begins at stage 2 and progresses in stage 3. This patient is able to perform most self-care activities. Caregiver role strain and adult failure to thrive occur later.

An older adult was stopped by police for driving through a red light. When asked for a driver's license, the adult hands the police officer a pair of sunglasses. What sign of dementia is evident? a. Aphasia b. Apraxia c. Agnosia d. Anhedonia

ANS: C Agnosia refers to the loss of sensory ability to recognize objects. Aphasia refers to the loss of language ability. Apraxia refers to the loss of purposeful movement. Anhedonia refers to a loss of joy in life.

The nurse is caring for a patient admitted with chronic obstructive pulmonary disease (COPD), angina, and hypertension. Before administering the prescribed daily dose of atenolol 100 mg PO, the nurse assesses the patient carefully. Which adverse effect is this patient at risk for given the patient's health history? A) Hypocapnia B) Tachycardia C)Bronchospasm D) Nausea and vomiting

C) Atenolol is a cardioselective β1-adrenergic blocker that reduces blood pressure and could affect the β2-receptors in the lungs with larger doses or with drug accumulation. Although the risk of bronchospasm is less with cardioselective β-blockers than nonselective β-blockers, atenolol should be used cautiously in patients with COPD.

The nurse is caring for a patient admitted with chronic obstructive pulmonary disease (COPD), angina, and hypertension. Before administering the prescribed daily dose of atenolol 100 mg PO, the nurse assesses the patient carefully. Which adverse effect is this patient at risk for given the patient's health history? A) Hypocapnia B) Tachycardia C) Bronchospasm D) Nausea and vomiting

C) Atenolol is a cardioselective β1-adrenergic blocker that reduces blood pressure and could affect the β2-receptors in the lungs with larger doses or with drug accumulation. Although the risk of bronchospasm is less with cardioselective β-blockers than nonselective β-blockers, atenolol should be used cautiously in patients with COPD.

The nurse teaches a 28-yr-old man newly diagnosed with hypertension about lifestyle modifications to reduce his blood pressure. Which patient statement requires reinforcement of teaching? A) "I will avoid adding salt to my food during or after cooking." B) "If I lose weight, I might not need to continue taking medications." C) "I can lower my blood pressure by switching to smokeless tobacco." D) "Diet changes can be as effective as taking blood pressure medications."

C) Nicotine contained in tobacco products (smoking and chew) cause vasoconstriction and increase blood pressure. Persons with hypertension should restrict sodium to 1500 mg/day by avoiding foods high in sodium and not adding salt in preparation of food or at meals. Weight loss can decrease blood pressure between 5 to 20 mm Hg. Following dietary recommendations (e.g., the DASH diet) lowers blood pressure, and these decreases compare with those achieved with blood pressure-lowering medication.

A 44-yr-old man is diagnosed with hypertension and receives a prescription for benazepril (Lotensin). After providing instruction, which statement by the patient indicates correct understanding? a) "If I take this medication, I will not need to follow a special diet." b) "It is normal to have some swelling in my face while taking this medication." c) "I will need to eat foods such as bananas and potatoes that are high in potassium." d) "If I develop a dry cough while taking this medication, I should notify my doctor."

D) Benazepril is an angiotensin-converting enzyme inhibitor. The medication inhibits breakdown of bradykinin, which may cause a dry, hacking cough. Other adverse effects include hyperkalemia. Swelling in the face could indicate angioedema and should be reported immediately to the prescriber. Patients taking drug therapy for hypertension should also attempt lifestyle modifications to lower blood pressure such as a reduced-sodium diet.

Despite a high dosage, a male patient who is taking nifedipine (Procardia XL) for antihypertensive therapy continues to have blood pressures over 140/90 mm Hg. What should the nurse do next? a) Assess his adherence to therapy. b) Ask him to make an exercise plan. c) Instruct him to use the DASH diet. d) Request a prescription for a thiazide diuretic.

a) A long-acting calcium-channel blocker such as nifedipine causes vascular smooth muscle relaxation, resulting in decreased systemic vascular resistance and arterial blood pressure and related side effects. The patient data the nurse has about this patient is very limited, so the nurse needs to begin by assessing adherence to therapy.

The family members of a client with early-stage Alzheimer's disease cannot provide adequate supervision for the client. What would be a reasonable alternative for the nurse to explore with them to meet their current needs? a) Day care b) Acute care hospitalization c) Long-term institutionalization d) Group home residency

a) Day care is a good option for clients with early-stage Alzheimer's disease. It provides supervision, a protected environment, and supportive interactions. The other options may be considered as the client moves into the advances stages of the disease disorder.

A patient recently admitted to the hospital has been diagnosed with delirium. The family of the patient asks the nurse to explain what delirium is. How should the nurse respond? a) Delirium is reversible with treatment of the underlying cause. b) Delirium is progressive and has no known cure. c) Delirium affects a specific area of cognitive functioning. d) Delirium indicates the onset of a cerebrovascular accident.

a) Delirium can be reversible with treatment of the precipitating problem and control of predisposing factors. Dementia is progressive and irreversible. Focal cognitive disorders affect a single area of cognitive functioning. Memory and orientation may be affected by a cerebrovascular accident (stroke), but delirium is not a sign of a stroke.

The nurse caring for a client diagnosed with Alzheimer's disease can anticipate that the family will need information about which medication therapy? a) Antihypertensives b) Benzodiazepines c) Immunosuppressants d) Acetylcholinesterase inhibitors

d) Memory deficit is thought to be related to a lack of acetylcholine at the synaptic level. Acetylcholinesterase inhibitor drugs prevent the chemical that destroys acetylcholine from acting, thus leaving more available acetylcholine.

The nurse is reviewing the needs of a patient with cognitive impairment. What is the priority concern that the nurse should address for this patient? a) Promoting at least 6 hours of sleep a night b) Encouraging an oral intake of 1200 calories per day c) Managing the patient's pain from arthritis d) Supervising medication administration

d) Safety is the priority concern for the cognitively impaired patient; safely taking medication addresses safety needs for the patient. Sleep, nutrition, and management of pain are important components of the patient's care and can affect overall health, but safety is the highest priority.

Which blood pressure (BP) finding by the nurse indicates that no changes in therapy are needed for a 48-yr-old patient with newly diagnosed hypertension? a. 98/56 mm Hg c. 128/92 mm Hg b. 128/76 mm Hg d. 142/78 mm Hg

ANS: B The 8th Joint National Committee's recommended goal for antihypertensive therapy for a 30- to 59-yr-old patient with hypertension is a BP below 140/90 mm Hg. The BP of 98/56 mm Hg may indicate overtreatment of the hypertension and an increased risk for adverse drug effects. The other two blood pressures indicate a need for modifications in the patient's treatment.

A patient diagnosed with delirium is experiencing perceptual alterations. Which environmental adjustment should the nurse make for this patient? a. Provide a well-lit room without glare or shadows. Limit noise and stimulation. b. Maintain soft lighting day and night. Keep a radio on low volume continuously. c. Light the room brightly day and night. Awaken the patient hourly to assess mental status. d. Keep the patient by the nurse's desk while awake. Provide rest periods in a room with a television on.

ANS: A A quiet, shadow-free room offers an environment that produces the fewest sensory perceptual distortions for a patient with cognitive impairment associated with delirium. The other options have the potential to produce increased perceptual alterations.

An older adult patient takes multiple medications daily. Over 2 days, the patient developed confusion, slurred speech, an unsteady gait, and fluctuating levels of orientation. These findings are most characteristic of: a. delirium. b. dementia. c. amnestic syndrome. d. Alzheimer's disease.

ANS: A Delirium is characterized by an abrupt onset of fluctuating levels of awareness, clouded consciousness, perceptual disturbances, and disturbed memory and orientation. The onset of dementia or Alzheimer's disease, a type of dementia, is more insidious. Amnestic syndrome involves memory impairment without other cognitive problems.

An elderly person presents with symptoms of delirium. The family reports, "Everything was fine until yesterday." What is the most important assessment information for the nurse to gather? a. A list of all medications the person currently takes b. Whether the person has experienced any recent losses c. Whether the person has ingested aged or fermented foods d. The person's recent personality characteristics and changes

ANS: A Delirium is often the result of medication interactions or toxicity. The distracters relate to MAOI therapy and depression.

An older adult is prescribed digoxin (Lanoxin) and hydrochlorothiazide daily as well as lorazepam (Ativan) as needed for anxiety. Over 2 days, the patient developed confusion, slurred speech, an unsteady gait, and fluctuating levels of orientation. What is the most likely reason for the patient's change in mental status? a. Drug actions and interactions b. Benzodiazepine withdrawal c. Hypotensive episodes d. Renal failure

ANS: A Drug actions and interactions are common among elderly persons and predispose this population to delirium. Delirium is characterized by an abrupt onset of fluctuating levels of awareness, clouded consciousness, perceptual disturbances, and disturbed memory and orientation. The patient takes lorazepam on a PRN basis, so withdrawal is unlikely. Hypotensive episodes or problems with renal function may occur associated with the patient's drug regime, but interactions are more likely the problem

Consider these health problems: Lewy body disease, frontal-temporal lobar degeneration, and Huntington's disease. Which term unifies these problems? a. Cyclothymia b. Dementia c. Delirium d. Amnesia

ANS: B The listed health problems are all forms of dementia.

A cognitively impaired patient newly admitted to the hospital is experiencing signs of sundown syndrome. Which intervention is best for the nurse to implement? a. Leave a night light on in the room at all times. b. Leave the television on at night with the volume up. c. Restrain the patient to maintain safety during the confusion. d. Administer a sleeping medication to help the patient sleep.

ANS: A Having a night light on for the patient can help orient them to their surroundings. Having the flickering light and sound from a television will not help a confused patient remain calm or oriented. Restraining a patient will increase their agitation and actually increase their risk of injury if they try to get out of bed. Sleeping medications often increase confusion in cognitively impaired patients.

An older adult patient in the intensive care unit has visual and auditory illusions. Which intervention will be most helpful? a. Using the patient's glasses and hearing aids b. Placing personally meaningful objects in view c. Placing large clocks and calendars on the wall d. Assuring that the room is brightly lit but very quiet at all times

ANS: A Illusions are sensory misperceptions. Glasses and hearing aids help clarify sensory perceptions. Without glasses, clocks, calendars, and personal objects are meaningless. Round-the-clock lighting promotes sensory overload and sensory perceptual alterations.

An 82-year-old patient who is in the hospital awakens from sleep and is disoriented to where she is at the present time. The nurse reorients the patient to her surroundings and helps the patient return to sleep. What data does the nurse consider as a probable cause of the patient's confusion? a. Pain medication received earlier in the night b. The death of the patient's spouse 2 years ago c. The patient's history of diabetes d. The age of the patient

ANS: A Medications such as narcotics, hypertensives, sleeping meds, and others can cause disorientation and symptoms of delirium. The death of a spouse is more likely to cause depression than disorientation. A history of diabetes alone does not cause disorientation. Normal aging alone does not cause disorientation, although it is a risk factor.

A patient has progressive memory deficits associated with dementia. Which nursing intervention would best help the individual function in the environment? a. Assist the patient to perform simple tasks by giving step-by-step directions. b. Reduce frustration by performing activities of daily living for the patient. c. Stimulate intellectual function by discussing new topics with the patient. d. Read one story from the newspaper to the patient every day.

ANS: A Patients with cognitive impairment should perform all tasks of which they are capable. When simple directions are given in a systematic fashion, the patient is better able to process information and perform simple tasks. Stimulating intellectual functioning by discussing new topics is likely to prove frustrating for the patient. Patients with cognitive deficits may enjoy the attention of someone reading to them, but this activity does not promote their function in the environment.

A hospitalized patient diagnosed with delirium misinterprets reality, while a patient diagnosed with dementia wanders about the home. Which outcome is the priority in both scenarios? The patients will: a. remain safe in the environment. b. participate actively in self-care. c. communicate verbally. d. acknowledge reality.

ANS: A Risk for injury is the nurse's priority concern. Safety maintenance is the desired outcome. The other outcomes are lower priorities and may not be realistic.

The charge nurse observes a new registered nurse (RN) doing discharge teaching for a patient with hypertension who has a new prescription for enalapril (Vasotec). The charge nurse will need to intervene if the new RN tells the patient to a. increase the dietary intake of high-potassium foods. b. make an appointment with the dietitian for teaching. c. check the blood pressure (BP) at home at least once a day. d. move slowly when moving from lying to sitting to standing.

ANS: A The ACE inhibitors cause retention of potassium by the kidney, so hyperkalemia is a possible adverse effect. The other teaching by the new RN is appropriate for a patient with newly diagnosed hypertension who has just started therapy with enalapril.

Goals of care for an older adult patient diagnosed with delirium caused by fever and dehydration will focus on: a. returning to premorbid levels of function. b. identifying stressors negatively affecting self. c. demonstrating motor responses to noxious stimuli. d. exerting control over responses to perceptual distortions.

ANS: A The desired overall goal is that the delirious patient will return to the level of functioning held before the development of delirium. Demonstrating motor response to noxious stimuli is an indicator appropriate for a patient whose arousal is compromised. Identifying stressors that negatively affect the self is too nonspecific to be useful for a patient with delirium. Exerting control over responses to perceptual distortions is an unrealistic indicator for a patient with sensorium problems related to delirium.

The nurse is reviewing the laboratory test results for a patient who has recently been diagnosed with hypertension. Which result is most important to communicate to the health care provider? a. Serum creatinine of 2.8 mg/dL c. Serum hemoglobin of 14.7 g/dL b. Serum potassium of 4.5 mEq/L d. Blood glucose level of 96 mg/dL

ANS: A The elevated serum creatinine indicates renal damage caused by the hypertension. The other laboratory results are normal.

Which nursing action should the nurse take first to assist a patient with newly diagnosed stage 1 hypertension in making needed dietary changes? a. Collect a detailed diet history. b. Provide a list of low-sodium foods. c. Help the patient make an appointment with a dietitian. d. Teach the patient about foods that are high in potassium.

ANS: A The initial nursing action should be assessment of the patient's baseline dietary intake through a thorough diet history. The other actions may be appropriate, but assessment of the patient's baseline should occur first.

The nurse on the intermediate care unit received change-of-shift report on four patients with hypertension. Which patient should the nurse assess first? a. 48-yr-old with a blood pressure of 160/92 mm Hg who reports chest pain b. 52-yr-old with a blood pressure of 198/90 mm Hg who has intermittent claudication c. 50-yr-old with a blood pressure of 190/104 mm Hg who has a creatinine of 1.7 mg/dL d. 43-yr-old with a blood pressure of 172/98 mm Hg whose urine shows microalbuminuria

ANS: A The patient with chest pain may be experiencing acute myocardial infarction and rapid assessment and intervention are needed. The symptoms of the other patients also show target organ damage but are not indicative of acute processes.

An older adult with moderately severe dementia forgets where the bathroom is and has episodes of incontinence. Which intervention should the nurse suggest to the patient's family? a. Label the bathroom door. b. Take the older adult to the bathroom hourly. c. Place the older adult in disposable adult briefs. d. Limit the intake of oral fluids to 1000 ml per day.

ANS: A The patient with moderately severe dementia has memory loss that begins to interfere with activities. This patient may be able to use environmental cues such as labels on doors to compensate for memory loss. Regular toileting may be helpful, but a 2-hour schedule is often more reasonable. Placing the patient in disposable briefs is more appropriate at a later stage. Severely limiting oral fluid intake would predispose the patient to a urinary tract infection.

What is the priority nursing diagnosis for a patient with fluctuating levels of consciousness, disturbed orientation, and visual and tactile hallucinations? a. Risk for injury related to altered cerebral function, fluctuating levels of consciousness, disturbed orientation, and misperception of the environment b. Bathing/hygiene self-care deficit related to cerebral dysfunction, as evidenced by confusion and inability to perform personal hygiene tasks c. Disturbed thought processes related to medication intoxication, as evidenced by confusion, disorientation, and hallucinations d. Fear related to sensory perceptual alterations as evidenced by visual and tactile hallucinations

ANS: A The physical safety of the patient is of highest priority among the diagnoses given. Many opportunities for injury exist when a patient misperceives the environment as distorted, threatening, or harmful or when the patient exercises poor judgment or when the patient's sensorium is clouded. The other diagnoses may be concerns, but are lower priorities.

Which assessment findings would the nurse expect in a patient experiencing delirium? Select all that apply. a. Impaired level of consciousness b. Disorientation to place, time c. Wandering attention d. Apathy e. Agnosia

ANS: A, B, C Disorientation to place and time is an expected finding. Orientation to person (self) usually remains intact. Attention span is short, and difficulty focusing or shifting attention as directed is often noted. Patients with delirium commonly experience illusions and hallucinations. Fluctuating levels of consciousness are expected. Agnosia occurs with dementia. Apathy is associated with depression.

The nurse is teaching primary prevention of cognitive impairment at a community health fair. Which topics would be included in the presentation? (Select all that apply.) a. Do not use substances such as cannabis and alcohol. b. Wear helmets when riding bicycles and motorcycles. c. Complete a Mini Mental Status Exam (MMSE) yearly. d. Correct acid-base imbalances related to underlying disease processes. e. Wear a seat belt whenever riding in a motorized vehicle. f. Complete a Confusion Assessment Method (CAM) scale yearly.

ANS: A, B, E Primary prevention attempts to prevent injury. Not using chemical substances, wearing a helmet, and wearing a seat belt are all measures to prevent injury to the brain, which protects cognitive function. An MMSE and CAM are secondary prevention, or screening tools performed once symptoms are present. Correcting acid-base imbalances from underlying disease processes is a tertiary prevention level, aimed at minimizing complications for disease already present.

A patient diagnosed with moderately severe Alzheimer's disease has a self-care deficit of dressing and grooming. Designate appropriate interventions to include in the patient's plan of care. Select all that apply. a. Provide clothing with elastic and hook-and-loop closures. b. Label clothing with the patient's name and name of the item. c. Administer anti-anxiety medication before bathing and dressing. d. Provide necessary items and direct the patient to proceed independently. e. If the patient resists dressing, use distraction and try again after a short interval.

ANS: A, B, E Providing clothing with elastic and hook-and-loop closures facilitates patient independence. Labeling clothing with the patient's name and the name of the item maintains patient identity and dignity (provides information if the patient has agnosia). When a patient resists, it is appropriate to use distraction and try again after a short interval because patient moods are often labile. The patient may be willing to cooperate given a later opportunity. Providing the necessary items for grooming and directing the patient to proceed independently are inappropriate. Be prepared to coach by giving step-by-step directions for each task as it occurs. Administering anxiolytic medication before bathing and dressing is inappropriate. This measure would result in unnecessary overmedication.

Which assessment finding would be likely for a patient experiencing a hallucination? The patient: a. looks at shadows on a wall and says, "I see scary faces." b. states, "I feel bugs crawling on my legs and biting me." c. reports telepathic messages from the television. d. speaks in rhymes.

ANS: B A hallucination is a false sensory perception occurring without a corresponding sensory stimulus. Feeling bugs on the body when none are present is a tactile hallucination. Misinterpreting shadows as faces is an illusion. An illusion is a misinterpreted sensory perception. The other incorrect options apply to thought insertion and clang associations.

Consider these diagnostic findings: apolipoprotein E (apoE) malfunction, neurofibrillary tangles, neuronal degeneration in the hippocampus, and brain atrophy. Which health problem corresponds to these diagnostic findings? a. Huntington's disease b. Alzheimer's disease c. Parkinson's disease d. Vascular dementia

ANS: B All of the options relate to dementias; however, the pathophysiological phenomena described apply to Alzheimer's disease. Parkinson's disease is associated with dopamine dysregulation. Huntington's disease is genetic. Vascular dementia is the consequence of circulatory changes.

The nurse has just finished teaching a hypertensive patient about the newly prescribed drug, ramipril (Altace). Which patient statement indicates that more teaching is needed? a. "The medication may not work well if I take aspirin." b. "I can expect some swelling around my lips and face." c. "The doctor may order a blood potassium level occasionally." d. "I will call the doctor if I notice that I have a frequent cough."

ANS: B Angioedema occurring with angiotensin-converting enzyme (ACE) inhibitor therapy is an indication that the ACE inhibitor should be discontinued. The patient should be taught that if any swelling of the face or oral mucosa occurs, the health care provider should be immediately notified because this could be life threatening. The other patient statements indicate that the patient has an accurate understanding of ACE inhibitor therapy.

A patient with hypertension who has just started taking atenolol (Tenormin) returns to the health clinic after 2 weeks for a follow-up visit. The blood pressure (BP) is unchanged from the previous visit. Which action should the nurse take first? a. Tell the patient why a change in drug dosage is needed. b. Ask the patient if the medication is being taken as prescribed. c. Inform the patient that multiple drugs are often needed to treat hypertension. d. Question the patient regarding any lifestyle changes made to help control BP.

ANS: B Because nonadherence with antihypertensive therapy is common, the nurse's initial action should be to determine whether the patient is taking the atenolol as prescribed. The other actions also may be implemented, but these would be done after assessing patient adherence with the prescribed therapy.

What is the priority intervention for a patient diagnosed with delirium who has fluctuating levels of consciousness, disturbed orientation, and perceptual alterations? a. Distraction using sensory stimulation b. Careful observation and supervision c. Avoidance of physical contact d. Activation of the bed alarm

ANS: B Careful observation and supervision are of ultimate importance because an appropriate outcome would be that the patient will remain safe and free from injury. Physical contact during care cannot be avoided. Activating a bed alarm is only one aspect of providing for the patient's safety.

During morning care, a nurse asks a patient diagnosed with dementia, "How was your night?" The patient replies, "It was lovely. I went out to dinner and a movie with my friend." Which term applies to the patient's response? a. Sundown syndrome b. Confabulation c. Perseveration d. Delirium

ANS: B Confabulation refers to making up of stories or answers to questions by a person who does not remember. It is a defensive tactic to protect self-esteem and prevent others from noticing memory loss. The patient's response was not sundown syndrome. Perseveration refers to repeating a word or phrase over and over. Delirium is not present in this scenario.

Which assessment finding for a patient who is receiving IV furosemide (Lasix) to treat stage 2 hypertension is most important to report to the health care provider? a. Blood glucose level of 175 mg/dL b. Serum potassium level of 3.0 mEq/L c. Orthostatic systolic BP decrease of 12 mm Hg d. Most recent blood pressure (BP) reading of 168/94 mm Hg

ANS: B Hypokalemia is a frequent adverse effect of the loop diuretics and can cause life-threatening dysrhythmias. The health care provider should be notified of the potassium level immediately and administration of potassium supplements initiated. The elevated blood glucose and BP also indicate a need for collaborative interventions but will not require action as urgently as the hypokalemia. An orthostatic drop of 12 mm Hg will require intervention only if the patient is symptomatic.

An older patient has been diagnosed with possible white coat hypertension. Which planned action by the nurse best addresses the suspected cause of the hypertension? a. Instruct the patient about the need to decrease stress levels. b. Teach the patient how to self-monitor and record BPs at home. c. Schedule the patient for regular blood pressure (BP) checks in the clinic. d. Inform the patient and caregiver that major dietary changes will be needed.

ANS: B In the phenomenon of "white coat" hypertension, patients have elevated BP readings in a clinical setting and normal readings when BP is measured elsewhere. Having the patient self-monitor BPs at home will provide a reliable indication about whether the patient has hypertension. Regular BP checks in the clinic are likely to be high in a patient with white coat hypertension. There is no evidence that this patient has elevated stress levels or a poor diet, and those factors do not cause white coat hypertension.

A nurse working in a pediatric clinic recognizes that which child is most at risk for cognitive impairment? a. An infant who is being fed reconstituted powdered formula b. A toddler living in an older home that is being remodeled c. A preschooler who attends a play group 3 days a week d. A school-age child who rides a school bus 5 days a week

ANS: B Older homes frequently have lead-based paint; paint chips generated by remodeling put toddlers, who often put foreign objects in their mouths, at risk for exposure to lead which is a known toxic substance that can affect cognitive function. Powdered formulas, attendance at play groups, or riding on a school bus are not known to impair cognitive development.

A nurse counsels the family of a patient diagnosed with Alzheimer's disease who lives at home and wanders at night. Which action is most important for the nurse to recommend to enhance safety? a. Apply a medical alert bracelet to the patient. b. Place locks at the tops of doors. c. Discourage daytime napping. d. Obtain a bed with side rails.

ANS: B Placing door locks at the top of the door makes it more difficult for the patient with dementia to unlock the door because the ability to look up and reach upward is diminished. The patient will try to climb over side rails, increasing the risk for injury and falls. Avoiding daytime naps may improve the patient's sleep pattern but does not assure safety. A medical alert bracelet will be helpful if the patient leaves the home, but it does not prevent wandering or assure the patient's safety.

A patient with severe dementia no longer recognizes family members and becomes anxious and agitated when they attempt reorientation. Which alternative could the nurse suggest to the family members? a. Wear large name tags. b. Focus interaction on familiar topics. c. Frequently repeat the reorientation strategies. d. Place large clocks and calendars strategically.

ANS: B Reorientation may seem like arguing to a patient with cognitive deficit and increases the patient's anxiety. Validating, talking with the patient about familiar, meaningful things, and reminiscing give meaning to existence both for the patient and family members. The option that suggests using validating techniques when communicating is the only option that addresses an interactional strategy. Wearing large name tags and placing large clocks and calendars strategically are reorientation strategies. Frequently repeating the reorientation strategies is inadvisable because patients with dementia sometimes become more agitated with reorientation.

A patient with a history of hypertension treated with a diuretic and an angiotensin-converting enzyme (ACE) inhibitor arrives in the emergency department complaining of a severe headache and nausea and has a blood pressure (BP) of 238/118 mm Hg. Which question should the nurse ask to follow up on these findings? a. "Have you recently taken any antihistamines?" b. "Have you consistently taken your medications?" c. "Did you take any acetaminophen (Tylenol) today?" d. "Have there been recent stressful events in your life?"

ANS: B Sudden withdrawal of antihypertensive medications can cause rebound hypertension and hypertensive crisis. Although many over-the-counter medications can cause hypertension, antihistamines and acetaminophen do not increase BP. Stressful events will increase BP but not usually to the level seen in this patient.

Which action will the nurse in the hypertension clinic take to obtain an accurate baseline blood pressure (BP) for a new patient? a. Deflate the BP cuff at a rate of 5 to 10 mm Hg per second. b. Have the patient sit in a chair with the feet flat on the floor. c. Assist the patient to the supine position for BP measurements. d. Obtain two BP readings in the dominant arm and average the results.

ANS: B The patient should be seated with the feet flat on the floor. The BP is obtained in both arms, and the results of the two arms are not averaged. The patient does not need to be in the supine position. The cuff should be deflated at 2 to 3 mm Hg per second.

The nurse is assessing a patient who has been admitted to the intensive care unit (ICU) with a hypertensive emergency. Which finding is most important to report to the health care provider? a. Urine output over 8 hours is 250 mL less than the fluid intake. b. The patient cannot move the left arm and leg when asked to do so. c. Tremors are noted in the fingers when the patient extends the arms. d. The patient complains of a headache with pain at level 7 of 10 (0 to 10 scale).

ANS: B The patient's inability to move the left arm and leg indicates that a stroke may be occurring and will require immediate action to prevent further neurologic damage. The other clinical manifestations are also likely caused by the hypertension and will require rapid nursing actions, but they do not require action as urgently as the neurologic changes.

The nurse obtains the following information from a patient newly diagnosed with prehypertension. Which finding is most important to address with the patient? a. Low dietary fiber intake b. No regular physical exercise c. Drinks a beer with dinner every night d. Weight is 5 pounds above ideal weight

ANS: B The recommendations for preventing hypertension include exercising aerobically for 30 minutes most days of the week. A weight that is 5 pounds over the ideal body weight is not a risk factor for hypertension. The Dietary Approaches to Stop Hypertension (DASH) diet is high in fiber, but increasing fiber alone will not prevent hypertension from developing. The patient's alcohol intake is within guidelines and will not increase the hypertension risk.

An elderly patient is admitted with delirium secondary to a urinary tract infection. The family asks whether the patient will ever recover. Select the nurse's best response. a. "The health care provider is the best person to answer your question." b. "The confusion will probably get better as we treat the infection." c. "Unfortunately, delirium is a progressively disabling disorder." d. "I will be glad to contact the chaplain to talk with you."

ANS: B Usually, as the underlying cause of the delirium is treated, the symptoms of delirium clear. The distracters mislead the family.

A 56-yr-old patient who has no previous history of hypertension or other health problems suddenly develops a blood pressure (BP) of 198/110 mm Hg. After reconfirming the BP, it is appropriate for the nurse to tell the patient that a. a BP recheck should be scheduled in a few weeks. b. dietary sodium and fat content should be decreased. c. diagnosis, treatment, and ongoing monitoring will be needed. d. there is an immediate danger of a stroke, requiring hospitalization.

ANS: C A sudden increase in BP in a patient older than age 50 years with no previous hypertension history or risk factors indicates that the hypertension may be secondary to some other problem. The BP will need treatment and ongoing monitoring. If the patient has no other risk factors, a stroke in the immediate future is unlikely. There is no indication that dietary salt or fat intake have contributed to this sudden increase in BP, and reducing intake of salt and fat alone will not be adequate to reduce this BP to an acceptable level.

The nurse is reviewing new medication orders for several patients in a long-term care facility. Which patient does the nurse recognize as being at the highest risk for having cognitive impairment related to prescribed medications? a. The patient prescribed an antibiotic for a urinary tract infection. b. The patient prescribed a cholinesterase inhibitor for early Alzheimer's disease. c. The patient prescribed a beta-blocker for hypertension. d. The patient prescribed a bisphosphonate for osteoporosis.

ANS: C Anti-hypertensives such as the beta-blockers can cause adverse changes in cognition. While an infection can affect cognition, antibiotics do not generally cause cognitive changes. The cholinesterase inhibitors are prescribed to slow the progression in cognitive decline for patients diagnosed with Alzheimer's disease. Bisphosphonates are used for osteoporosis and are not generally a risk for altered cognition.

The nurse is sitting with the family of a patient who has just received the diagnosis of dementia. The family asks for information on what treatment will be needed to cure the condition. What is the nurse's best response? a. "Hormone therapy will reverse the condition." b. "Vitamin C and zinc will reverse the condition." c. "There is no treatment that reverses dementia." d. "Dementia can be reversed with diet, exercise, and medications."

ANS: C Currently there is no proven treatment that has been shown to reverse dementia, although some treatments can slow the progression of the illness. Hormone therapy, vitamin therapy, diet, and exercise are all important for overall health but do not reverse the progression of dementia.

A nurse gives anticipatory guidance to the family of a patient diagnosed with stage 3, mild cognitive decline Alzheimer's disease. Which problem common to that stage should the nurse address? a. Violent outbursts b. Emotional disinhibition c. Communication deficits d. Inability to feed or bathe self

ANS: C Families should be made aware that the patient will have difficulty concentrating and following or carrying on in-depth or lengthy conversations. The other symptoms are usually seen at later stages of the disease.

After the nurse teaches the patient with stage 1 hypertension about diet modifications that should be implemented, which diet choice indicates that the teaching has been most effective? a. The patient avoids eating nuts or nut butters. b. The patient restricts intake of chicken and fish. c. The patient drinks low-fat milk with each meal. d. The patient has two cups of coffee in the morning.

ANS: C For the prevention of hypertension, the Dietary Approaches to Stop Hypertension (DASH) recommendations include increasing the intake of calcium-rich foods. Caffeine restriction and decreased protein intake are not included in the recommendations. Nuts are high in beneficial nutrients and 4 to 5 servings weekly are recommended in the DASH diet.

Which information is most important for the nurse to include when teaching a patient with newly diagnosed hypertension? a. Most people are able to control BP through dietary changes. b. Annual BP checks are needed to monitor treatment effectiveness. c. Hypertension is usually asymptomatic until target organ damage occurs. d. Increasing physical activity alone controls blood pressure (BP) for most people

ANS: C Hypertension is usually asymptomatic until target organ damage has occurred. Lifestyle changes (e.g., physical activity, dietary changes) are used to help manage BP, but drugs are needed for most patients. Home BP monitoring should be taught to the patient and findings checked by the health care provider frequently when starting treatment for hypertension and then every 3 months when stable.

An older adult drove to a nearby store but was unable to remember how to get home or state an address. When police intervened, they found that this adult was wearing a heavy coat and hat, even though it was July. Which stage of Alzheimer's disease is evident? a. Preclinical Alzheimer's disease b. Mild cognitive decline c. Moderately severe cognitive decline d. Severe cognitive decline

ANS: C In the moderately severe stage, deterioration is evident. Memory loss may include the inability to remember addresses or the date. Activities such as driving may become hazardous, and frustration by the increasing difficulty of performing ordinary tasks may be experienced. The individual has difficulty with clothing selection. Mild cognitive decline (early-stage) Alzheimer's can be diagnosed in some, but not all, individuals. Symptoms include misplacing items and misuse of words. In the stage of severe cognitive decline, personality changes may take place, and the patient needs extensive help with daily activities. This patient has symptoms, so the preclinical stage does not apply.

An older adult who is cognitively impaired is admitted to the hospital with pneumonia. Which sign or symptom would the nurse expect to be exhibited by the patient? a. Severe headache b. Flank pain c. Increased confusion d. Decreased blood glucose

ANS: C Increased confusion is a symptom that occurs in cognitively impaired patients who experience an infection. Severe headache occurs with migraines, meningitis, and other conditions. Flank pain occurs with pyelonephritis. Blood glucose typically increases with an infection.

Which medication prescribed to patients diagnosed with Alzheimer's disease antagonizes N-Methyl-D-Aspartate (NMDA) channels rather than cholinesterase? a. Donepezil (Aricept) b. Rivastigmine (Exelon) c. Memantine (Namenda) d. Galantamine (Razadyne)

ANS: C Memantine blocks the NMDA channels and is used in moderate-to-late stages of the disease. Donepezil, rivastigmine, and galantamine are all cholinesterace inhibitors. These drugs increase the availability of acetylcholine and are most often used to treat mild-to-moderate Alzheimer's disease

Propranolol (Inderal) is prescribed for a patient diagnosed with hypertension. The nurse should consult with the health care provider before giving this drug when the patient reveals a history of a. daily alcohol use. c. reactive airway disease. b. peptic ulcer disease. d. myocardial infarction (MI).

ANS: C Nonselective b-blockers block b1- and b2-adrenergic receptors and can cause bronchospasm, especially in patients with a history of asthma. b-Blockers will have no effect on the patient's peptic ulcer disease or alcohol use. b-Blocker therapy is recommended after MI.

Two patients in a residential care facility have dementia. One shouts to the other, "Move along, you're blocking the road." The other patient turns, shakes a fist, and shouts, "You're trying to steal my car." What is the nurse's best action? a. Administer one dose of an antipsychotic medication to both patients. b. Reinforce reality. Say to the patients, "Walk along in the hall. This is not a traffic intersection." c. Separate and distract the patients. Take one to the day room and the other to an activities area. d. Step between the two patients and say, "Please quiet down. We do not allow violence here."

ANS: C Separating and distracting prevents escalation from verbal to physical acting out. Neither patient loses self-esteem during this intervention. Medication probably is not necessary. Stepping between two angry, threatening patients is an unsafe action, and trying to reinforce reality during an angry outburst will probably not be successful when the patients are cognitively impaired.

A patient has just been diagnosed with hypertension and has been started on captopril . Which information is most important to include when teaching the patient about this drug? a. Include high-potassium foods such as bananas in the diet. b. Increase fluid intake if dryness of the mouth is a problem. c. Change position slowly to help prevent dizziness and falls. d. Check blood pressure (BP) in both arms before taking the drug.

ANS: C The angiotensin-converting enzyme (ACE) inhibitors frequently cause orthostatic hypotension, and patients should be taught to change position slowly to allow the vascular system time to compensate for the position change. Increasing fluid intake may counteract the effect of the drug, and the patient is taught to use gum or hard candy to relieve dry mouth. The BP should be taken in the nondominant arm by newly diagnosed patients in the morning, before taking the drug, and in the evening. Because ACE inhibitors cause potassium retention, increased intake of high-potassium foods is inappropriate.

A patient who is dehydrated has been experiencing confusion. The daughter is concerned about taking the patient home in a confused state. What statement by the nurse is correct? a. "Don't worry; the patient should be fine once they are in a familiar environment." b. "I can make a referral for a home health aide to assist with the patient." c. "Once the dehydration is corrected, the patient's confusion should improve." d. "I can show you how to care for the patient once you return home."

ANS: C The confusion caused by an underlying medical condition is a temporary condition that can be corrected once the underlying condition is treated, in this case once the patient is rehydrated. It is not necessary to teach home care or make a referral to home health because it is not expected that the patient will be confused at discharge. Telling the daughter that there is nothing to worry about diminishes her concern and may decrease her trust in the nurse.

During change-of-shift report, the nurse obtains the following information about a hypertensive patient who received the first dose of nadolol (Corgard) during the previous shift. Which information indicates that the patient needs immediate intervention? a. The patient's pulse has dropped from 68 to 57 beats/min. b. The patient complains that the fingers and toes feel quite cold. c. The patient has developed wheezes throughout the lung fields. d. The patient's blood pressure (BP) reading is now 158/91 mm Hg.

ANS: C The most urgent concern for this patient is the wheezes, which indicate that bronchospasm (a common adverse effect of the noncardioselective -blockers) is occurring. The nurse should immediately obtain an O2 saturation measurement, apply supplemental O2, and notify the health care provider. The mild decrease in heart rate and complaint of cold fingers and toes are associated with -receptor blockade but do not require any change in therapy. The BP reading may indicate that a change in medication type or dose may be indicated. However, this is not as urgently needed as addressing the bronchospasm.

A patient with fluctuating levels of awareness, confusion, and disturbed orientation shouts, "Bugs are crawling on my legs. Get them off!" Which problem is the patient experiencing? a. Aphasia b. Dystonia c. Tactile hallucinations d. Mnemonic disturbance

ANS: C The patient feels bugs crawling on both legs, even though no sensory stimulus is actually present. This description meets the definition of a hallucination, a false sensory perception. Tactile hallucinations may be part of the symptom constellation of delirium. Aphasia refers to a speech disorder. Dystonia refers to excessive muscle tonus. Mnemonic disturbance is associated with dementia rather than delirium.

Which nursing diagnoses are most applicable for a patient diagnosed with severe Alzheimer's disease? Select all that apply. a. Acute confusion b. Anticipatory grieving c. Urinary incontinence d. Disturbed sleep pattern e. Risk for caregiver role strain

ANS: C, D, E The correct answers are consistent with problems frequently identified for patients with late-stage Alzheimer's disease. Confusion is chronic, not acute. The patient's cognition is too impaired to grieve.

A patient diagnosed with Alzheimer's disease calls the fire department saying, "My smoke detectors are going off." Firefighters investigate and discover that the patient misinterpreted the telephone ringing. Which problem is this patient experiencing? a. Hyperorality b. Aphasia c. Apraxia d. Agnosia

ANS: D Agnosia is the inability to recognize familiar objects, parts of one's body, or one's own reflection in a mirror. Hyperorality refers to placing objects in the mouth. Aphasia refers to the loss of language ability. Apraxia refers to the loss of purposeful movements, such as being unable to dress.

The nurse is caring for a 70-yr-old patient who uses hydrochlorothiazide and enalapril (Norvasc) but whose self-monitored blood pressure (BP) continues to be elevated. Which patient information may indicate a need for a change? a. Patient takes a daily multivitamin tablet. b. Patient checks BP daily just after getting up. c. Patient drinks wine three to four times a week. d. Patient uses ibuprofen (Motrin) treat osteoarthritis.

ANS: D Because use of nonsteroidal antiinflammatory drugs (NSAIDs) can prevent adequate BP control, the patient may need to avoid the use of ibuprofen. A multivitamin tablet will help supply vitamin D, which may help lower BP. BP decreases while sleeping, so self-monitoring early in the morning will result in obtaining pressures that are at their lowest. The patient's alcohol intake is not excessive.

Which action will be included in the plan of care when the nurse is caring for a patient who is receiving nicardipine (Cardene) to treat a hypertensive emergency? a. Organize nursing activities so that the patient has undisturbed sleep for 8 hours at night. b. Keep the patient NPO to prevent aspiration caused by nausea and possible vomiting. c. Assist the patient up in the chair for meals to avoid complications associated with immobility. d. Use an automated noninvasive blood pressure machine to obtain frequent measurements.

ANS: D Frequent monitoring of BP is needed when the patient is receiving rapid-acting IV antihypertensive medications. This can be most easily accomplished with an automated BP machine or arterial line. The patient will require frequent assessments, so allowing 8 hours of undisturbed sleep is not reasonable. When patients are receiving IV vasodilators, bed rest is maintained to prevent decreased cerebral perfusion and fainting. There is no indication that this patient is nauseated or at risk for aspiration, so an NPO status is unnecessary.

What is the priority need for a patient with late-stage dementia? a. Promotion of self-care activities b. Meaningful verbal communication c. Preventing the patient from wandering d. Maintenance of nutrition and hydration

ANS: D In late-stage dementia, the patient often seems to have forgotten how to eat, chew, and swallow. Nutrition and hydration needs must be met if the patient is to live. The patient is incapable of self-care, ambulation, or verbal communication.

The registered nurse (RN) is caring for a patient with a hypertensive crisis who is receiving sodium nitroprusside . Which nursing action can the nurse delegate to an experienced licensed practical/vocational nurse (LPN/LVN)? a. Evaluate effectiveness of nitroprusside therapy on blood pressure (BP). b. Assess the patient's environment for adverse stimuli that might increase BP. c. Titrate nitroprusside to decrease mean arterial pressure (MAP) to 115 mm Hg. d. Set up the automatic noninvasive BP machine to take readings every 15 minutes

ANS: D LPN/LVN education and scope of practice include the correct use of common equipment such as automatic noninvasive blood pressure machines. The other actions require advanced nursing judgment and education, and should be done by RNs.

Which action should the nurse take when giving the initial dose of oral labetalol to a patient with hypertension? a. Encourage the use of hard candy to prevent dry mouth. b. Teach the patient that headaches often occur with this drug. c. Instruct the patient to call for help if heart palpitations occur. d. Ask the patient to request assistance before getting out of bed.

ANS: D Labetalol decreases sympathetic nervous system activity by blocking both - and -adrenergic receptors, leading to vasodilation and a decrease in heart rate, which can cause severe orthostatic hypotension. Heart palpitations, dry mouth, dehydration, and headaches are possible side effects of other antihypertensives.

The nurse is developing a care plan for a patient newly admitted to a unit that cares for patients with cognitive impairment. What is an important component of care for the patients on this unit? a. Allow food selections from a menu with several choices. b. Schedule frequent field trips off the unit for cognitive stimulation. c. Plan for attendance at activities with several other patients on the unit. d. Plan for a structured daily routine of events and caregivers

ANS: D Patients with a cognitive impairment benefit from a predictable routine and consistent caregivers. Trips off of the unit may confuse the patient and disrupt their normal routine. Offering too many selections causes confusion and can lead to agitation. Being in large groups for activities can overstimulate the patient and lead to agitation and fear.

A older patient diagnosed with severe, late-stage dementia no longer recognizes family members. The family asks how long it will be before this patient recognizes them when they visit. What is the nurse's best reply? a. "Your family member will never again be able to identify you." b. "I think that is a question the health care provider should answer." c. "One never knows. Consciousness fluctuates in persons with dementia." d. "It is disappointing when someone you love no longer recognizes you."

ANS: D Therapeutic communication techniques can assist the family to come to terms with the losses and irreversibility dementia imposes on both the loved one and themselves. Two incorrect responses close communication. The nurse should take the opportunity to foster communication. Consciousness does not fluctuate in patients with dementia.

A patient with fluctuating levels of consciousness, disturbed orientation, and perceptual alteration begs, "Someone get these bugs off me." What is the nurse's best response? a. "No bugs are on your legs. You are having hallucinations." b. "I will have someone stay here and brush off the bugs for you." c. "Try to relax. The crawling sensation will go away sooner if you can relax." d. "I don't see any bugs, but I can tell you are frightened. I will stay with you."

ANS: D When hallucinations are present, the nurse should acknowledge the patient's feelings and state the nurse's perception of reality, but not argue. Staying with the patient increases feelings of security, reduces anxiety, offers the opportunity for reinforcing reality, and provides a measure of physical safety. Denying the patient's perception without offering help does not support the patient emotionally. Telling the patient to relax makes the patient responsible for self-soothing. Telling the patient that someone will brush the bugs away supports the perceptual distortions.

The nurse supervises an unlicensed assistant personnel (UAP) who is taking the blood pressure of 58-yr-old obese female patient admitted with heart failure. Which action by the UAP will require the nurse to intervene? a) Waiting 2 minutes after position changes to take orthostatic pressures b) Deflating the blood pressure cuff at a rate of 8 to 10 mm Hg per second c) Taking the blood pressure with the patient's arm at the level of the heart d) Taking a forearm blood pressure because the largest cuff will not fit the patient's upper arm

B) The cuff should be deflated at a rate of 2 to 3 mm Hg per second. The arm should be supported at the level of the heart for accurate blood pressure measurements. Using a cuff that is too small causes a falsely high reading and too large causes a falsely low reading. If the maximum size blood pressure cuff does not fit the upper arm, the forearm may be used. Orthostatic blood pressures should be taken within 1 to 2 minutes of repositioning the patient.

A family member reports that the client had been oriented and able to carry on a logical conversation last evening, but this morning is confused and disoriented. The nurse can suspect that the client is displaying symptoms associated with which cognitive disorder? a) Delirium b) Dementia c) Amnesic disorder d) Selective inattention

a) Delirium is characterized by a disturbance of consciousness, a change in cognition (such as impaired attention span), and a fluctuating level of consciousness that develop over a short period of time. None of the other options share these characteristics

A 90-year-old patient is admitted to the hospital. Shortly after admission, the family notices that the patient is exhibiting disorientation and agitation. When questioned about the behavior by the family, the nurse states that the patient is at risk for developing which common complication of hospitalization in older adults? a) Delirium b) Dementia c) Alzheimer's disease d) Sundowner syndrome

a) Delirium, which occurs over hours to a few days, is the most frequent complication of hospitalization in the elderly population. Dementia occurs over a period of months. Alzheimer's disease develops over months to years. Sundowner syndrome is most prominent in dementia and becomes worse in the evenings.

The nurse teaches a patient with hypertension that uncontrolled hypertension may damage organs in the body primarily by which mechanism? a) Hypertension promotes atherosclerosis and damage to the walls of the arteries. b) Hypertension causes direct pressure on organs, resulting in necrosis and replacement of cells with scar tissue. c) Hypertension causes thickening of the capillary membranes, leading to hypoxia of organ systems. d) Hypertension increases blood viscosity, which contributes to intravascular coagulation and tissue necrosis distal to occlusions.

a) Hypertension is a major risk factor for the development of atherosclerosis by mechanisms not yet fully known. However, when atherosclerosis develops, it damages the walls of arteries and reduces circulation to target organs and tissues.

What initial intervention should the nurse suggest to the family members of a client diagnosed with Alzheimer's disease who has become incontinence of urine? a) Label the bathroom door with a picture. b) Provide toileting on an as-needed basis. c) Apply disposable diapers. d) Encourage hourly toileting.

a) Labeling doors and various items with pictures can be helpful for a client who has forgotten where things are and what certain items are. The remaining options may need to be implemented eventually when such prompting is no longer effective.

The physician mentions to the nurse that a client who is about to be admitted has "sundowning." The nurse can expect to assess for which nightly behavior? a) Agitation b) Lethargy c) Depression d) Mania

a) Sundowning involves increased disorientation and agitation occurring at night. None of the other options are associated with sundowning.

A community health nurse is preparing a course on protecting cognitive function. Which population group should the nurse target for teaching? a) Older male adults with diabetes b) Older female adults who are overweight c) Young adults living in school dormitories d) Adolescents attending summer camps

a) The primary risk factor for cognitive impairment is advancing age; males with a history of stroke or diabetes are at significant risk. Older females with a history of poor health, insomnia, and lack of social support are at risk for cognitive impairment, not those who are overweight. Risk factors for young adults include substance abuse and high-risk behaviors, not crowded living conditions. Adolescents who attend summer camp are not necessarily at risk for cognitive problems; adolescents who participate in high-risk behaviors would be at risk.

The nurse is expected to perform an assessment of a client suspected to be in the earliest stage of Alzheimer's disease. What finding would be out of character for the client who truly has early stage Alzheimer's disease? Select all that apply. a) Easily frustrated by cognitive losses b) Charming behavior designed to hide memory deficit c) Confabulation to compensate for forgotten information d) Avoidance of questions by subject changing

a, Frustration and anger are characteristics of the middle stage of Alzheimer's. During early-stage Alzheimer's disease the client is aware of memory impairment and may attempt to disguise it or cover it by being evasive or using confabulation. The remaining options are associated with the early stage of Alzheimer's disease.REF: 438;

When preparing educational materials for the family of a client diagnosed with progressive dementia, the nurse should include information related to which local resourses? Select all that apply. a) Day care centers b) Legal professionals c) Home health services d) Family support groups e) Professional counseling

a, c, d, e Most importantly, families need to know where to get help. Help includes professional counseling and education regarding the process and progression of the disease. Families especially need to know about and be referred to community-based groups that can help shoulder this tremendous burden (e.g., day care centers, senior citizen groups, organizations providing home visits and respite care, and family support groups). While legal professionals may be of interest to the family, client and family education does not include such services.

When caring for elderly patients with hypertension, which information should the nurse consider when planning care (select all that apply.)? a) Systolic blood pressure increases with aging. b) Blood pressures should be maintained near 120/80 mm Hg. c) White coat syndrome is prevalent in elderly patients. d) Volume depletion contributes to orthostatic hypotension. e) Blood pressure drops 1 hour postprandially in many older patients. f) Older patients will require higher doses of antihypertensive medications.

a, c, d, e Systolic blood pressure increases with age and patients older than age 60 years should be maintained below 150/90 mm Hg. Older patients have significantly higher blood pressure readings when taken by health care providers (white coat syndrome). Older patients experience orthostatic hypotension related to dehydration, reduced compensatory mechanisms, and medications. One hour after eating, many older patients experience a drop in blood pressure. Lower doses of medications may be needed to control blood pressures in older adults related to decreased absorption rates and excretion ability.

The nurse is caring for a patient with hypertension who is scheduled to receive a dose of metoprolol (Lopressor). The nurse should withhold the dose and consult the prescribing physician for which vital sign taken just before administration? a) O2 saturation 93% b) Pulse 48 beats/min c) Respirations 24 breaths/min d) Blood pressure 118/74 mm Hg

b) Because metoprolol is a β1-adrenergic blocking agent, it can cause hypotension and bradycardia as adverse effects. The nurse should withhold the dose and consult with the health care provider for parameters regarding pulse rate limits.

The nurse admits a 73-yr-old male patient with dementia for treatment of uncontrolled hypertension. The nurse will closely monitor for hypokalemia if the patient receives which medication? a) Clonidine (Catapres) b) Bumetanide (Bumex) c) Amiloride (Midamor) d) Spironolactone (Aldactone)

b) Bumetanide is a loop diuretic. Hypokalemia is a common adverse effect of this medication. Amiloride is a potassium-sparing diuretic. Spironolactone is an aldosterone-receptor blocker. Hyperkalemia is an adverse effect of both amiloride and spironolactone. Clonidine is a central-acting α-adrenergic antagonist and does not cause electrolyte abnormalities.

When teaching a patient about dietary management of stage 1 hypertension, which instruction is most appropriate? a) Increase water intake. b) Restrict sodium intake. c) Increase protein intake. d) Use calcium supplements.

b) The patient should decrease intake of sodium. This will help to control hypertension, which can be aggravated by excessive salt intake, which in turn leads to fluid retention. Protein intake does not affect hypertension. Calcium supplements are not recommended to lower blood pressure.

When teaching how lisinopril (Zestril) will help lower the patient's blood pressure, which mechanism of action should the nurse explain? a) Blocks β-adrenergic effects b) Relaxes arterial and venous smooth muscle c) Inhibits conversion of angiotensin I to angiotensin II d) Reduces sympathetic outflow from central nervous system

c) Lisinopril is an angiotensin-converting enzyme inhibitor that inhibits the conversion of angiotensin I to angiotensin II, which reduces angiotensin II-mediated vasoconstriction and sodium and water retention. β blockers result in vasodilation and decreased heart rate. Direct vasodilators relax arterial and venous smooth muscle. Central acting α-adrenergic antagonists reduce sympathetic outflow from the central nervous system to produce vasodilation and decreased systemic vascular resistance and blood pressure.

A patient with a history of chronic hypertension is being evaluated in the emergency department for a blood pressure of 200/140 mm Hg. Which patient assessment question is the priority? a) Is the patient pregnant? b) Does the patient need to urinate? c) Does the patient have a headache or confusion? d) Is the patient taking antiseizure medications as prescribed?

c) The nurse's priority assessments include neurologic deficits, retinal damage, heart failure, pulmonary edema, and renal failure. The headache or confusion could be seen with hypertensive encephalopathy from increased cerebral capillary permeability leading to cerebral edema. In addition, headache or confusion could represent signs and symptoms of a hemorrhagic stroke. Pregnancy can lead to secondary hypertension. Needing to urinate and taking antiseizure medication do not support a hypertensive emergency.

The UAP is taking orthostatic vital signs. In the supine position, the blood pressure (BP) is 130/80 mm Hg, and the heart rate (HR) is 80 beats/min. In the sitting position, the BP is 140/80, and the HR is 90 beats/min. Which action should the nurse instruct the UAP to take next? a) Repeat BP and HR in this position. b) Record the BP and HR measurements. c) Take BP and HR with patient standing. d) Return the patient to the supine position

c) The vital signs taken do not reflect orthostatic changes, so the UAP will continue with the measurements while the patient is standing. There is no need to repeat or delay the readings. The patient does not need to return to the supine positon. When assessing for orthostatic changes, the UAP will take the BP and pulse in the supine position, then place the patient in a sitting position for 1 to 2 minutes and repeat the readings, and then reposition to the standing position for 1 to 2 minutes and repeat the readings. Results consistent with orthostatic changes would have a decrease of 20 mm Hg or more in systolic BP, a decrease of 10 mm Hg or more in diastolic BP, and/or an increase in HR of greater than or equal to 20 beats/min with position changes

The nurse is teaching a women's group about prevention of hypertension. What information should be included in the teaching for all the women (select all that apply.)? a) Lose weight. b) Limit nuts and seeds. c) Limit sodium and fat intake. d) Increase fruits and vegetables. e) Exercise 30 minutes most days.

c, d, e Primary prevention of hypertension is to make lifestyle modifications that prevent or delay the increase in BP. Along with exercise for 30 minutes on most days, the DASH eating plan is a healthy way to lower BP by limiting sodium and fat intake, increasing fruits and vegetables, and increasing nutrients that are associated with lowering BP. Nuts and seeds and dried beans are used for protein intake. Weight loss may or may not be necessary for the individual.

A client is brought to the hospital by her daughter, who visited this morning and found her mother to be confused and disoriented. When the client is admitted, the daughter states, "I'll take her glasses and hearing aid home, so they don't get lost." The best reply for the nurse would be: a) "That will be fine. I'll have you sign our hospital release form." b) "Because we do not have a copy of durable power of attorney, we cannot release them to you." c) "Don't worry. You can leave them at her bedside. We are insured for losses of this sort." d) "I would like to have your mother wear them. It will help her to be less confused or retain more of her orientation."

d) Clients with cognitive disorders usually profit from being able to see and hear clearly. Confusion is reduced through the use of glasses and hearing aids. None of the other options support this client need.

A 67-yr-old woman with hypertension is admitted to the emergency department with a blood pressure of 234/148 mm Hg and was started on nitroprusside (Nitropress). After one hour of treatment, the mean arterial blood pressure (MAP) is 55 mm Hg. Which nursing action is a priority? a) Start an infusion of 0.9% normal saline at 100 mL/hr. b) Maintain the current administration rate of the nitroprusside. c) Request insertion of an arterial line for accurate blood pressure monitoring. d) Stop the nitroprusside infusion and assess the patient for potential complications.

d) Nitroprusside is a potent vasodilator medication. A blood pressure of 234/118 mm Hg would have a calculated MAP of 177 mm Hg. Subtracting 25% (or 44 mm Hg) = 133 mm Hg. The initial treatment goal is to decrease MAP by no more than 25% within minutes to 1 hour. For this patient, the goal MAP would be approximately 133 mm Hg. Minimal MAP required to perfuse organs is around 60 to 65 mm Hg. Lowering the blood pressure too rapidly may decrease cerebral, coronary, or renal perfusion and could precipitate a stroke, myocardial infarction, or renal failure. The priority is to stop the nitroprusside infusion and then use fluids only if necessary to support restoration of MAP.

The nurse is establishing a therapeutic environment for a patient admitted with dementia and influenza. Which intervention would be important for the nurse to implement? a) Keep a radio on all the time to provide sound for the patient. b) Decrease patient confusion by limiting verbal interactions. c) Limit family visits to one person for 30 minutes per day. d) Provide a quiet environment in a private room.

d) The patient experiencing dementia needs a quiet environment with a minimum of unfamiliar stimulation from a roommate. A patient with dementia does not need extra stimulation from having a radio on continually. The nurse should speak clearly and quietly to the patient before any procedure or assistance to decrease agitation. Family visits would be encouraged because family members are familiar to the patient and their presence increases a sense of security.
