PD

which neurologic disorder has paradoxical i ntoxication as a potential adverse effect of medication therapy?

PD RATIONALE paradocical intoxication involves the aggravation, rather than the relief, of symptoms, after using a drug. dopaminergic drugs, prescribed for parkisonism, may vause paradoxical intoxication after prolonged use.

which neurodegenerative disorder has the characteristics of rigidity and bradykinesia?

PD RATIONALE PD is a chronic, progressice neurodegenerative disorder charachterized my an increase muscle tone (rigidity), slowness in the initiation and execution of movement (bradykinesia), tremors, and gait disturbances.

apomorphine (Apokyn) RATIONALE hypomobility is a condition in pt w parkinsonism. Drug such as apomorphine, a dopamine agonist, block the re uptake of dopamine into the presynaptic neurons and stimulates the postsynaptic dopamine receptor.

for the pt w MS, which action would the nurse classify as a PRIORITY intervention when developing the pt plan of care?

assest the pt identify the factors that precipitate exacerbations

which changes in vital signs indicate that the pt who has just stood up is experiencing postural hypotension?

decreased SBP, decrease DBP, and/or increased HR RATIONALE BP drops as the volume of circulating blood decreases when a pt abruptly stands from a lying or sitting position. The HR increases as the heart attempts to compensate by increasing the amount of circulating blood by increasing cardiac output.

Huntington's disease

deficiency of the neurotransmitters GABA and acetylcholine, which leads to the excessive release of dopamine. - genetacally transmitted - autosimal dominant disorder - no effective treatment - offspring has 50% chance - advanced HD provide palliative care as the collaborative approach

a pt w hypertension receives a prescription for lisipril. which mechanism of action would the nurse expect from this medication?

inhibits conversion of angiotensin I to angiotensin II RATIONALE lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that inhibits the conversion of angiotensin I to angiotensin II, which reduces angiotensin II mediated vasoconstriction and sodium and water retention

relapsing-remitting MS

involves developing and resolving symptoms ovr a few weeks to months before the pt returns to the baseline.

which medication overdose may lead to paradocical intoxication in a pt w PD

levodopa (L-dopa)

the nurse provides discharge teaching to a female pt whi was newly diagnosed w primary hypertension. Which instruction would be included?

limit the intake of alcohol to no more than one drink per day RATIONALE excessive alcohol is strongly associated w hypertension. Women and lighter-weight men should limit to no more than 1 drink a day. - sodium should be less than or equal to 1500 mg/day

which medication should be used with caution in ot w diabetes because the drug may depress the tachycardia associated w hypoglycemia?

metoprolol RATIONALE it is a B-adrenergic receptor blocker (B-blocker), slows the heart rate. tachycardia is a classic sympto, of hypoglycemia, therefor the pt must be aware of the decrease hr to devrease glucose levels

the nurse is assessing a pt for orthostatic HYPOtension. first, the nurse measured the BP and HR w the pt in supine position. which action would the nurse take next?

move the pt to a sitting position and measure the BP and HR within 2 minutes: - and then the pt stand and the BP and HR are measured with in 2 minutes - decrease by 20 or more in SBP - decrease of 10 or more in DBP - increase in pulse >20 b/per minute from supine to standing

which disease process includes Lhermitte's sign as a clinical manifestation?

multiple sclerosis (MS) RATIONALE lhermitte's sign is a transient sensory symptom manifested in pt w MS and is decribed as an electric shock radiating down the spine or into the limbs w flexion of the neck.

which medication classification would the nurse expect for a new med prescribed to treat the major symptoms of a pt w MS?

muscle relaxant RATIONALE MS causes muscle spascity as loss of the myelin sheath progressess. Muscle relaxants ease this spasms. - use of analgestics treats severe pain which is NOT associates w MS

a decreased # of acetylcholine receptors in the neuromuskular junction is a characterestiv of which autoimmune diseas?

myasthenia gravis RATIONALE antibodies attach acetylcholine receptors MEDICATION - azathioprine (Imuran) immunomodulator - prednisone (deltrasone); corticosteroid - pyridostigmine (Mestinon) anticholinergic Symptoms - difficulty swallowin - dif chewing - dif eye movement - dif facial mobility

for the pt w an aggressive form of MS who is not responding to teriflunomide (Aubagio) and dalfampridine (Ampyra), the prescriber changed the medication to natalizumab )Tysabri) and mitoxantrone (Novantrone). Later, when the pt develops progressive multifocal leukoencephalopathy, which prescribed med. might be responsible?

ondansetron (Zofran) and apomorphine (Apokyn) RATIONALE when administering dopamine agonist apomorphine alone, the med causes n/v. When administered w antiemetic such as ondansetron, leads to very low BP and loss consciousness.

the nurse is teaching an older pt w hypertension about developing an exercise program. Which instruction woild the nurse include?

perform muscle- stregthening activities twice a week RATIONALE - weightlifting is not recommended for hypertension becuase it increases BP. -

when evaluating the presence of an initial symptom of PD, which clinical manifistation would the nurse evaluate

pill-rolling tremors RATIONALE this are coarse resting tremmors of the fingers and thumb "pill rolling movement"

which mechanism of hypertension causes target organ damage

promotion of atherosclerosis and damage ti the walls of the arteries RATIONALE hypertension is a major risk factor for the development of atherosclerosis by mechanis, not known yet. once atherosclerosis develops it damages the walls of the arteries and reduces the circulation to target organs and tissue.

for which major complication would the nurse monitor development in a pt experiencing a myasthenic crisis?

repiratory indufficiency

the nurse is preparing to measure the BP of a pt who is lying down on a bed. Which techniques should the nurse use?

rest the pt arm on a pillow during the BP measurement RATIONALE raise and support the arm with a small pillow at the heart level. this allows the blood to drain from the arm and prevents inaccurate reading

which instruction is important for the nurse to provide ti a pt about the management of stage 1 hypertension?

restrict sodium intake RATIONALE salt leads to water retention

B- afrenergic receptor blockers (B-blockers)

result in vasodialation and decreases heart rate

when planning the care for a pt w MS who has an exacerbation of sensory deficits, for which pt problem would the nurse develop nursing interventions?

risk for injury RATIONALE MS usually exhibits itself on one side more than another. therefore the gait is unsteady, so there is an increase in the pt fall risk.

a relapsing-remitting initial course followed by the disease w or with out relapses are chareacteristics of which type of MS?

secondary- progressive

which lab test result indicates the presence of target organ damage in a pt w hypertension

serum creatine of 2.6 mg (normal 0.6-1.30) RATIONALE indicater target organ damage to the kidneys

which intervention would the nurse implement as a priority when providing care for a pt w MS?

vigilant infection control and adherence to standard precautions RATIONALE infection control is a PRIORITY in the care of pt w MS because infections is the most common cause of an exacerbation of the disease.

as treatment for hypertension crisis, a pt has received sodium nitroprusside for 3 days. for which reason would the nurse plan on monitoring the pt thiocynate levels?

the medication is metabolized to cyanide, then thiocyanate RATIONALE sodium nitoprusside causes arterial vasodilation and reduces systemic vascular resistance. this in turn, decreases the BP. It can ren reach lethal levels of thiocynate

Which instruction would the nurse provide the pt w MS who received a new prescription for interferon?

the medication often causes pt to experience flu- like symptoms RATIONALE it is an immunomodulator that treats the disease process and prevents relapse. -it is administered sub q every other day

a pt who has been taking clonifine for 10 years tells the nurse, "I decided to quit taking the medication a few days ago'. for which manifestation would the nurse monitor this pt?

tremors RATIONALE sudden discontinuation may cause withdrawal syndrome, including - rebound hypertension - tachycardia - HA - tremors - apprehension - sweating
