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

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

A client with myasthenia gravis who is taking neostigmine is experiencing frequent exacerbations of myasthenic crisis and cholinergic crisis. The nurse teaches the client that it is most important that this medication be taken in which manner? 1.On time 2.On an empty stomach 3.Double-dosed if 1 dose is missed 4.Titrated for dosage, depending on symptoms

1.On time Rationale: The client should take neostigmine exactly on time. Taking the medication early or late could result in myasthenic or cholinergic crisis. Taking the medication on time is especially important for the client with dysphagia because the client may not be able to swallow the medication if it is given late. These clients are taught to set an alarm clock to remind them of dosage times. The medication should be administered with food or milk to minimize side and adverse effects. The client should never skip or double up on missed doses or titrate the dose, depending on symptoms. The client needs to take the medication exactly as prescribed.

The primary health care provider has prescribed a lidocaine 5% patch for a client with a diagnosis of neck pain due to osteoarthritis. Which should the nurse tell the client regarding this medication? 1.The medication patch will act as a local anesthetic. 2.The medication patch acts by decreasing muscle spasms. 3.The medication is prescribed to cause the skin to peel below the patch. 4.Apply a heating pad to the area after applying the medication patch to increase the effectiveness.

1.The medication patch will act as a local anesthetic. Rationale: A lidocaine patch provides a local anesthetic effect to the site of application. The medication does not act in a systemic manner. It is not prescribed to cause the skin to peel, so if this reaction occurs, the primary health care provider should be notified. A heating pad should not be applied because irritation or burning of the skin may occur.

The nurse is providing medication instructions to a client with multiple sclerosis receiving baclofen. Which information should the nurse include in the instructions? 1.Watch for urinary retention as a side effect. 2.Stop taking the medication if diarrhea occurs. 3.Restrict fluid intake while taking this medication. 4.Notify the primary health care provider if fatigue occurs.

1.Watch for urinary retention as a side effect Rationale: Baclofen, a skeletal muscle relaxant, also is a central nervous system (CNS) depressant, which can cause urinary retention. The client should not restrict fluid intake. Constipation, rather than diarrhea, is an adverse effect of baclofen. Fatigue is a CNS effect that is most intense during the early phase of therapy and diminishes with continued medication use. It is not necessary to notify the primary health care provider if fatigue occurs.

The primary health care provider is preparing to administer edrophonium to the client with myasthenia gravis. In planning care, the nurse understands which about the administration of edrophonium? Select all that apply. 1.Edrophonium is a long-acting cholinesterase inhibitor. 2.Atropine is used to reverse the effects of edrophonium. 3.If symptoms worsen following administration of edrophonium, the crisis is cholinergic. 4.Edrophonium is used to distinguish between a myasthenic crisis and a cholinergic crisis. 5.An improvement in symptoms following administration of edrophonium indicates myasthenic crisis.

2, 3, 4, 5 Rationale: Edrophonium is an ultra-short-acting reversible cholinesterase inhibitor that can be used to distinguish between a cholinergic and a myasthenic crisis. To distinguish between overtreatment (cholinergic crisis) and undertreatment (myasthenic crisis), edrophonium is administered; this is often referred to as a Tensilon test. Overtreatment of myasthenia gravis with reversible cholinesterase inhibitors results in a cholinergic crisis. Undertreatment can result in a myasthenic crisis. Both cholinergic and myasthenic crises result in increased muscle weakness or paralysis. If symptoms improve after the administration of edrophonium, the crisis is myasthenic; if symptoms worsen, the crisis is cholinergic. Atropine must be readily available so that edrophonium can be reversed if the symptoms worsen.

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

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

A client with osteoarthritis is receiving diclofenac sodium. The nurse would be concerned about the administration of this medication if the client's history and physical included a diagnosis of which condition? 1.Graves' disease 2.Peptic ulcer disease 3.Coronary artery disease 4.Benign prostatic hypertrophy

2.Peptic ulcer disease

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

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

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

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

The nurse is assisting in the care of a client who is being evaluated for possible myasthenia gravis. The primary health care provider gives a test dose of edrophonium. Evaluation of the results indicates that the test is positive. Which would be the expected response noted by the nurse? 1.Joint pain for the next 15 minutes 2.An immediate increase in blood pressure 3.An increase in muscle strength within 1 to 3 minutes 4.Feelings of faintness or dizziness for 5 to 10 minutes

3.An increase in muscle strength within 1 to 3 minutes Rationale: Edrophonium is a short-acting acetylcholinesterase inhibitor used to diagnose myasthenia gravis. An increase in muscle strength should be seen in 1 to 3 minutes following the test dose if the client does have the disease. If no response occurs, another dose is given over the next 2 minutes and muscle strength is tested again. If no increase in muscle strength occurs with this higher dose, the muscle weakness is not caused by myasthenia gravis. Clients who receive injections of this medication commonly demonstrate a drop in blood pressure, feel faint and dizzy, and are flushed.

The nurse is assisting in the care of a client with myasthenia gravis who is receiving pyridostigmine. Which medication should the nurse plan to have readily available should the client develop cholinergic crisis because of excessive medication dosage? 1.Vitamin K 2.Acetylcysteine 3.Atropine sulfate 4.Protamine sulfate

3.Atropine sulfate Rationale: If the client is in cholinergic crisis, the antidote for the medication would be a medication that is an anticholinergic. Thus, the antidote for cholinergic crisis is atropine sulfate. Vitamin K is the antidote for warfarin. Protamine sulfate is the antidote for heparin, and acetylcysteine is the antidote for acetaminophen.

The nurse is administering an intravenous dose of methocarbamol to a client with multiple sclerosis. For which adverse effect should the nurse monitor? 1.Tachycardia 2.Rapid pulse 3.Bradycardia 4.Hypertension

3.Bradycardia Rationale: Intravenous administration of methocarbamol can cause hypotension and bradycardia. The nurse needs to monitor for these adverse effects. Options 1, 2, and 4 are not effects with administration of this medication.

Baclofen is prescribed for the client with multiple sclerosis. The nurse determines that the medication is having the intended effect if which finding is noted in the client? 1.Increased muscle tone 2.Increased range of motion 3.Decreased muscle spasms 4.Decreased local pain and tenderness

3.Decreased muscle spasms Rationale: Baclofen is a skeletal muscle relaxant and acts at the spinal cord level to decrease the frequency and degree of muscle spasms in clients with multiple sclerosis, spinal cord injury, or other diseases. The other options are incorrect.

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

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

The nurse is preparing to ambulate a client with Parkinson's disease who has recently been started on levodopa/carbidopa. Before performing this activity with the client, the nurse should include which most importantassessment in the client's plan of care? 1.History of falls 2.Use of assistive devices 3.Postural (orthostatic) vital signs 4.Degree of exhibited intention tremor

3.Postural (orthostatic) vital signs Rationale: Clients with Parkinson's disease are at risk for postural (orthostatic) hypotension from the disease. This problem is exacerbated with the introduction of levodopa/carbidopa, which also can cause postural hypotension and increase the client's risk for falls. Although knowledge of the client's use of assistive devices and history of falls is helpful, neither of these options is the most important element of the assessment, based on the wording of this question. Clients with Parkinson's disease generally have resting tremor, not intention tremor.

The nurse is caring for a client with Parkinson's disease. Which finding about gait should the nurse expect to note in the client? 1.Walking on the toes 2.Unsteady and staggering 3.Shuffling and propulsive 4.Broad-based and waddling

3.Shuffling and propulsive Rationale: The parkinsonian gait is characterized by short, accelerating, shuffling steps. The client leans forward with the head, hips, and knees flexed and has difficulty starting and stopping. An ataxic gait is unsteady and staggering. A dystrophic gait is broad-based and waddling. Walking on the toes can occur from shortened Achilles tendons.

The nurse is instructing a client with Parkinson's disease about preventing falls. Which client statement reflects a need for further teaching? 1. "I can sit down to put on my pants and shoes." 2. "I try to exercise every day and rest when I'm tired." 3. "My son removed all loose rugs from my bedroom." 4. "I don't need to use my walker to get to the bathroom."

4. "I don't need to use my walker to get to the bathroom." Rationale: The client with Parkinson's disease should be instructed regarding safety measures in the home. The client should use her or his walker as support to get to the bathroom because of bradykinesia. The client should sit down to put on pants and shoes to prevent falling. The client should exercise every day in the morning when energy levels are highest. The client should have all loose rugs in the home removed to prevent falling.

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

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

A client with myasthenia gravis has difficulty chewing and has received a prescription for pyridostigmine. The nurse should check to see that the client takes the medication at what time? 1.With meals 2.Between meals 3.Just after meals 4.30 minutes before meals

4.30 minutes before meals Rationale: Pyridostigmine is a cholinergic medication used to increase muscle strength in the client with myasthenia gravis. For the client who has difficulty chewing, the medication should be administered 30 minutes before meals to enhance the client's ability to eat. The times noted in the remaining options will not be helpful to the client.

A client with myasthenia gravis has become increasingly weaker. The primary health care provider prepares to identify whether the client is reacting to an overdose of the medication (cholinergic crisis) or an increasing severity of the disease (myasthenic crisis). An injection of edrophonium is administered. Which finding would indicate that the client is in cholinergic crisis? 1.No change in the condition 2.Complaints of muscle spasms 3.An improvement of the weakness 4.A temporary worsening of the condition

4.A temporary worsening of the condition Rationale: An edrophonium injection makes the client in cholinergic crisis temporarily worse. An improvement in the weakness indicates myasthenia crisis. Muscle spasms are not associated with this test.

A client with myasthenia gravis becomes increasingly weaker. The primary health care provider injects a dose of edrophonium to determine whether the client is experiencing a myasthenic crisis or a cholinergic crisis. The nurse expects that the client will have which reaction if in cholinergic crisis? 1.No change in the condition 2.Complaints of muscle spasms 3.An improvement of the weakness 4.A temporary worsening of the condition

4.A temporary worsening of the condition Rationale: An edrophonium injection makes the client in cholinergic crisis temporarily worse. An improvement of the condition indicates myasthenic crisis. The other options are unrelated to the test.

Carbidopa-levodopa is prescribed for a client with Parkinson's disease. The nurse monitors the client for side and adverse effects of the medication. Which finding indicates that the client is experiencing an adverse effect? 1.Pruritus 2.Tachycardia 3.Hypertension 4.Impaired voluntary movements

4.Impaired voluntary movements Rationale: Dyskinesia and impaired voluntary movements may occur with high carbidopa-levodopa dosages. Nausea, anorexia, dizziness, orthostatic hypotension, bradycardia, and akinesia are frequent side effects of the medication.

The nurse is caring for a client with osteoarthritis. The nurse performs an assessment knowing that which clinical manifestations are associated with the disorder? Select all that apply.' 1.Elevated white blood cell count 2.A decreased sedimentation rate 3.Joint pain that diminishes after rest 4.Elevated antinuclear antibody levels 5.Joint pain that intensifies with activity

3.Joint pain that diminishes after rest 5.Joint pain that intensifies with activity Rationale: The stiffness and joint pain that occur in osteoarthritis diminish after rest and intensify with activity. No specific laboratory findings are useful in diagnosing osteoarthritis. The client may have a normal or slightly elevated sedimentation rate. Morning stiffness lasting longer than 30 minutes occurs in rheumatoid arthritis. Elevated white blood cell counts, platelet counts, and antinuclear antibody levels occur in rheumatoid arthritis.

A client with Parkinson's disease has begun therapy with levodopa/carbidopa. The nurse determines that the client understands the action of the medication if he or she verbalizes that results may not be apparent for how long? 1. 1 week 2. 24 hours 3. 2 to 3 days 4. 2 to 3 weeks

4. 2 to 3 weeks Rationale: Signs and symptoms of Parkinson's disease usually begin to resolve within 2 to 3 weeks of starting therapy, although in some clients marked improvement may not be seen for up to 6 months. The client needs to understand this concept to aid in compliance with medication therapy.

The nurse is caring for a client with an exacerbation of multiple sclerosis. Which medication(s) will the nurse expect to be prescribed to hasten recovery from the exacerbation? 1.Carbamazepine and phenytoin by mouth 2.Lioresal by mouth and diazepam intravenously 3.Phenytoin intravenously, then tapered to oral route 4.Methylprednisolone and cyclophosphamide intravenously

4.Methylprednisolone and cyclophosphamide intravenously Rationale: Intravenous methylprednisolone or adrenocorticotropic hormone in combination with cyclophosphamide may be prescribed to accelerate recovery from an exacerbation of multiple sclerosis. Carbamazepine may be prescribed for trigeminal neuralgia, and phenytoin may be prescribed to control seizures. Lioresal and diazepam are used to treat muscle spasticity.

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

1. Chew food thoroughly. 2. Cut food into very small pieces. 3. Sit straight up in the chair while eating. 5. Swallow when the chin is tipped slightly downward to the chest. Rationale: The client avoids swallowing any type of food or drink with the head lifted upward, which could actually cause aspiration by opening the glottis. The client should be advised to sit upright while eating, not to talk with food in the mouth (talking requires opening the glottis), cut food into very small pieces, chew thoroughly, and tip the chin downward to swallow.

The nurse is assigned to care for a client with multiple sclerosis who is receiving an intravenous dose of methocarbamol. The nurse monitors the client knowing that which is an expected side effect? 1.Insomnia 2.Excitability 3.Hypertension 4.Dark green-colored urine

4.Dark green-colored urine Rationale: Methocarbamol is a skeletal muscle relaxant. It may cause the urine to turn a brown, black, or dark green color, and the client needs to be told that this is a harmless effect. This medication can cause hypotension. Drowsiness and dizziness can also occur. Therefore, the remaining options are incorrect.

The nurse in a long-term care facility is reviewing the primary health care provider's (PHCP's) prescriptions on an assigned client. The nurse notes that the PHCP prescribed ropinirole hydrochloride. The nurse determines that this medication has been prescribed to treat which condition in the client? 1.Depression 2.Diabetes mellitus 3.Coronary artery disease 4.Parkinsonian syndrome

4.Parkinsonian syndrome Rationale: Ropinirole hydrochloride is a medication that is used to treat idiopathic parkinsonian syndrome. It normally is administered 3 times a day to treat the client. This medication is not used to treat depression, diabetes mellitus, or coronary artery disease.

Diclofenac is prescribed for a client with osteoarthritis. Which medication, if noted on the client's record, would alert the nurse to consult with the primary health care provider? 1.Phenytoin 2.Primidone 3.Acetaminophen 4.Warfarin sodium

4.Warfarin sodium Rationale: Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). Interactions may occur with the use of anticoagulants, and the nurse should consult with the primary health care provider about a potential medication interaction if an anticoagulant is prescribed. Phenytoin and primidone are anticonvulsant medications, and acetaminophen is a nonopioid analgesic. These medications are not contraindicated with diclofenac

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

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

The nurse who is caring for a client with myasthenia gravis has a prescription to perform an edrophonium test. After obtaining edrophonium the nurse should be certain that which also is available at the bedside? 1.Atropine sulfate 2.Protamine sulfate 3.Calcium gluconate 4.Magnesium sulfate

1.Atropine sulfate Rationale: An edrophonium test is performed to distinguish between myasthenic and cholinergic crisis. After administration of the edrophonium, if symptoms intensify, the crisis is cholinergic. Because the symptoms of cholinergic crisis will worsen with the administration of edrophonium, atropine sulfate should be available because it is the antidote. Protamine sulfate is the antidote for heparin. Calcium gluconate is the antidote for magnesium sulfate toxicity.

A client is suspected of having myasthenia gravis. Edrophonium is administered intravenously to determine the diagnosis. Which indicates that the client may have myasthenia gravis? 1.Joint pain following administration of the medication 2.Feelings of faintness, dizziness, hypotension, and signs of flushing in the client 3.A decrease in muscle strength within 30 to 60 seconds following administration of the medication 4.An increase in muscle strength within 30 to 60 seconds following administration of the medication

4.An increase in muscle strength within 30 to 60 seconds following administration of the medication Rationale: Edrophonium is a short-acting acetylcholinesterase inhibitor used as a diagnostic agent. When a client has suspected myasthenia gravis, the health care provider will administer an edrophonium test. When a dose is administered intravenously, an increase in muscle strength should be seen in 30 to 60 seconds. If no response occurs, another dose of edrophonium is given over the next 2 minutes, and muscle strength is tested again. If no increase in muscle strength occurs with this higher dose, the muscle weakness is not caused by myasthenia gravis. Clients receiving injections of this medication commonly demonstrate a drop in blood pressure, feel faint and dizzy, and are flushed.

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

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

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

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

The nurse is caring for a client with myasthenia gravis who has received edrophonium by the intravenous route to test for myasthenic crisis. The client asks the nurse how long the improvement in muscle strength will last. Which response should the nurse make to the client? 1."It will last for 4 to 5 minutes." 2."It will last for about 30 minutes." 3."It will last longer than 60 minutes." 4."It will last approximately 10 minutes."

1."It will last for 4 to 5 minutes." Rationale: Edrophonium commonly is given to test for myasthenic crisis. If the client is in myasthenic crisis, muscle strength improves after administration of the medication. Within 30 to 60 seconds, most myasthenic clients show a marked improvement in muscle tone that lasts for 4 to 5 minutes. Options 2, 3, and 4 are incorrect.

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

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

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

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

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

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

A client with multiple sclerosis is receiving baclofen. The nurse assessing the client monitors for which finding as an indication of a primarytherapeutic response to the medication? 1.Decreased nausea 2.Decreased muscle spasms 3.Increased muscle tone and strength 4.Increased range of motion of all extremities

2.Decreased muscle spasms Rationale: Baclofen is a skeletal muscle relaxant and acts at the spinal cord level to decrease the frequency and amplitude of muscle spasms in clients with spinal cord injuries or diseases or with multiple sclerosis. Increased muscle tone and strength and increased range of motion of all extremities are not directly related to the effects of this medication. Decreased nausea is an incorrect option.

A client with multiple sclerosis is receiving diazepam, a centrally acting skeletal muscle relaxant. Which finding, if noted during the nursing assessment, would indicate that the client is experiencing a side/adverse effect of this medication? 1.Headache 2.Drowsiness 3.Urinary retention 4.Increased salivation

2.Drowsiness Rationale: Incoordination and drowsiness are common side/adverse effects of diazepam. The remaining options are unrelated to the use of this medication.

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

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

Carbidopa-levodopa is prescribed for a client with Parkinson's disease. The nurse monitors the client for side and adverse effects of the medication. Which finding indicates that the client is experiencing an adverse effect? 1. Pruritus 2. Tachycardia 3. Hypertension 4. Impaired voluntary movements

4. Impaired voluntary movements Rationale: Dyskinesia and impaired voluntary movements may occur with high carbidopa-levodopa dosages. Nausea, anorexia, dizziness, orthostatic hypotension, bradycardia, and akinesia are frequent side effects of the medication.

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

4.400 to 500 mL with each meal and 200 to 250 mL at midmorning, midafternoon, and late afternoon Rationale: Spacing fluid intake over the day helps the client with a neurogenic bladder to establish regular times for successful voiding. Omitting intake after the evening meal minimizes incontinence or the need to empty the bladder during the night.

A client with myasthenia gravis has become increasingly weaker. The primary health care provider prepares to identify whether the client is reacting to an overdose of the medication (cholinergic crisis) or an increasing severity of the disease (myasthenic crisis). An injection of edrophonium is administered. Which finding would indicate that the client is in cholinergic crisis? 1. No change in the condition 2. Complaints of muscle spasms 3.An improvement of the weakness 4.A temporary worsening of the condition

4.A temporary worsening of the condition Rationale: An edrophonium injection makes the client in cholinergic crisis temporarily worse. An improvement in the weakness indicates myasthenia crisis. Muscle spasms are not associated with this test.
