Both drugs have the same pharmacodynamic and side effect profiles. ·d. Levodopa-carbidopa acts as a dopamine agonist, whereas ropinirole directly replaces dopamine.

·a. Ropinirole is a dopamine agonist that has fewer side effects than levodopa-carbidopa. (Ropinirole (Requip) is a newer antiparkinson drug that directly stimulates specific dopamine receptors. Because the drug itself is not dopamine, there are fewer side effects related to peripheral dopamine levels than are noted with carbidopa.)

A nurse working on an inpatient psychiatric unit hears in report that a client taking an antipsychotic drug has begun showing signs of dystonia. The nurse expects the client to exhibit which of the following on assessment? 1.Shuffling gait 2.Muscle quivering 3.Eyes rolled back in the head 4.Lip smacking

3.Eyes rolled back in the head Acute dystonic reactions typically present within 24 to 48 hours of an initial dose or dose increase of an antipsychotic drug and are more often observed in the high-potency/low-dose typical agents. Symptoms classically present as oculogyric crisis (eyes rolled back in the head), trismus (facial twisting to one side), a protruding and fixed tongue, and opisthotonus (neck arching and stiffness).

A client will be starting drug therapy with fluoxetine (Prozac). The nurse cautions the client not to stop taking the drug suddenly because this could result in which of the following symptoms? 1.Dizziness and agitation 2.Tachycardia and fever 3.Insomnia and sexual dysfunction 4.Urinary retention and abdominal cramps

ANS: Dizziness and agitation Fluoxetine is a selective serotonin uptake inhibitor. Discontinuation of these drugs is associated with a classic withdrawal response of dizziness, nausea, and agitation.

The client is started on selegiline (Eldepryl) therapy. What information is most important for the nurse to teach the client about this medication? ·a. "This medication will cure your disease." ·b. "This medication is used when other drugs do not work." ·c. "This medication blocks breakdown of dopamine." ·d. "You will need to restrict your intake of certain foods and drinks."

·d. "You will need to restrict your intake of certain foods and drinks." (This medication may inhibit MAO-A, an enzyme that promotes metabolism of tyramine in the gastrointestinal tract. If not metabolized, ingestion of foods high in tyramine, such as aged cheese, red wine and bananas, can cause a hypertensive crisis. This is the most important information the nurse needs to teach the client.)

The nurse is teaching the client who is prescribed an anticholinergic about dietary changes that might be necessary. What instruction is the most appropriate for this client? ·a. Do not drink milk while on this medication. ·b. Increase your intake of fatty foods while on this therapy. ·c. Do not eat carbohydrates with this medication. ·d. Increase your intake of fluids while on this medication.

·d. Increase your intake of fluids while on this medication. (The client should be encouraged to ingest foods high in fiber and increase fluid intake to prevent constipation.)

The nurse anticipates that a client with hyperaldosteronism will have an order for which of the following diuretics? 1. Spironolactone (Aldactone) 2.Amiloride (Midamor) 3.Triamterene (Dyrenium) 4.Bumetanide (Bumex)

1. Spironolactone (Aldactone) Spironolactone is used in the treatment of primary hyperaldosteronism.

The nurse would assess the client taking lithium (Eskalith) for signs of toxicity whenever the serum lithium level rises above which of the following levels? 1. 0.5 mEq/L 2. 1.0 mEq/L 3. 1.5 mEq/L 4. 2.0 mEq/L

1.5 mEq/L remember normal is 0.5-1.5 dry mouth lethargy fatigue muscle weakness

When teaching a patient about carbidopa-levodopa (Sinemet), the nurse responds based on knowledge that A) carbidopa decreases levodopa's conversion in the periphery, increasing the levodopa available to cross the blood-brain barrier. B) carbidopa increases levodopa's conversion in the periphery, enhancing the amount of dopamine available to the brain. C) giving both drugs together minimizes side effects. D) carbidopa crosses the blood-brain barrier to increase the metabolism of levodopa to dopamine in the brain.

A) carbidopa decreases levodopa's conversion in the periphery, increasing the levodopa available to cross the blood-brain barrier. Adding carbidopa to levodopa inhibits the breakdown of levodopa in the periphery, increasing the amount available to cross the blood-brain barrier and decreasing the extrapyramidal adverse effects caused by dopamine in the periphery, resulting in fewer unwanted adverse effects.

The patient asks the nurse to explain the difference between carbidopa-levodopa (Sinemet) and ropinirole (Requip). The nurse's response is based on knowledge that A) ropinirole is a dopamine agonist that has fewer side effects than carbidopa-levodopa. B) carbidopa-levodopa is less effective than ropinirole in treating the symptoms of Parkinson's disease. C) both drugs have the same pharmacodynamic and side effect profiles. D) carbidopa-levodopa acts as a dopamine agonist, whereas ropinirole directly replaces dopamine.

A) ropinirole is a dopamine agonist that has fewer side effects than carbidopa-levodopa. Ropinirole stimulates specific dopamine receptors in the brain. It is more specific for the receptors associated with parkinsonian symptoms, the D2 subfamily of dopamine receptors. This in turn may have more specific antiparkinson effects, with fewer adverse effects associated with generalized dopaminergic stimulation.

A client has an order for liquid haloperidol (Haldol). The nurse should avoid administering the medication with which of the following beverages? 1. Tea 2. Water 3. Apricot juice 4. Grape juice

ANS: 1 A special dropper should be used for oral liquid haloperidol administration; a precipitate will form if it is diluted with tea or coffee. If dilution is desired, use at least 60 mL of diluent (water or apricot or grape juice) and mix it just before administration to prevent precipitation.

The nurse working in a mental health outpatient setting is scheduling a follow-up visit for a client who is just beginning drug therapy with clozapine (Clozaril). The nurse makes an appointment for the client to return to the clinic in 1. 3 days. 2. 1 week. 3. 2 weeks. 4. 1 month.

ANS: 2 Because clozapine has the potential for causing agranulocytosis, a potentially life-threatening effect, it is reserved for treatment-resistant schizophrenia or for when adverse effects to other drugs preclude their continued use. Treatment with clozapine is closely monitored, with the manufacturer recommending that only weekly supplies be dispensed and that weekly white blood cell testing be performed.

Before beginning drug therapy with an antipsychotic agent, priority assessments done by the nurse would include which of the following? 1. Neurologic and respiratory 2. Neurologic and cardiovascular 3. Cardiovascular and renal 4. Respiratory and renal

ANS: 2 Before starting antipsychotic drug therapy, a client should undergo a complete history and physical assessment. Of particular importance is a neurologic examination and documentation of orientation, affect, and cognition as a baseline assessment. Obtaining a baseline assessment of pulse and blood pressure in the sitting, standing, and lying positions is also important.

The nurse anticipates an order for which medication? A. bacitracin B. mupirocin (Bactroban) C. clindamycin (Cleocin T) D. clotrimazole (Lotrimin)

ANS: B Mupirocin (Bactroban) is used on the skin for treatment of staphylococcal and streptococcal impetigo. It is used topically and intranasally to treat nasal colonization by MRSA. The other options are incorrect. Bacitracin and clindamycin are not indicated for the treatment of MRSA; clotrimazole is an antifungal drug

A teenage boy is taking tretinoin for his acne. Part of the information the nurse should include in the teaching plan is that A. he should avoid foods heavy in salt and oils. B. the drug may cause increased redness of the skin. C. he should use abrasive cleansers to remove old skin layers. D. extremes of weather and sunlight should not bother him during therapy.

Get a prescription for a second product, malathion. B. Try one of the lotion products that remain on the scalp for 8 hours. C. Be sure that he is using a nit comb to remove nits from the hair shafts. D. Comb through the hair with mineral oil to loosen the lice from the hair shafts.

ANS: C Before trying another product, ensure that he is performing the regimen correctly. Because he only mentioned shampooing, ensure that after each shampoo he is using a nit comb to remove nits, or eggs, from the hair shafts.

A patient has been taking donepezil (Aricept) for 2 weeks as part of the treatment for early stages of Alzheimer's disease. Her daughter calls the physician's office and is upset because "Mother has not improved one bit!" Which response by the nurse is appropriate? A. "Increase the dosage to twice daily." B. "It takes time for the cure to take effect." C. "It may take up to 6 weeks to see an improvement." D. "Take the medication on an empty stomach for improved absorption."

ANS: C Donepezil therapy is not a cure for Alzheimer's disease, but it may help to improve symptoms in the early stages. It may take up to 6 weeks to see improvement. The family should be taught that the medication must be taken exactly as ordered and with meals, and the medication should not be abruptly stopped or the dosage increased without the physician's approval because of the possibility of serious complications.

The nurse is providing teaching regarding drug therapy to the husband of a woman with Alzheimer's disease. She was diagnosed 3 months ago, has mild memory loss, and will be receiving donepezil (Aricept). What is the drug's action? A. Prevents memory loss in later stages B. Reverses the course of Alzheimer's disease C. Provides sedation to prevent agitation and restlessness D. May help to improve the symptoms of Alzheimer's disease

ANS: D Donepezil is used to treat mild to moderate dementia occurring in Alzheimer's disease and may improve the symptoms of the disease.

Which comment to the nurse indicates more teaching is needed for a client taking carbidopa/levodopa? A. "I know I need to take this drug once a day." B. "I know I shouldn't stop taking this drug abruptly." C. "I understand my urine may become dark and discolored." D. "I know it may take a few weeks or months to control my symptoms."

Answer: A Rationale: A statement from the client such as "I know I need to take this drug once a day" indicates that more teaching is needed because carbidopa/levodopa has a short half-life and must be taken 3 or 4 times per day. The other answers are true.

Cholinergic (parasympathomimetic) drugs are indicated for which situation? A. Treating a postoperative patient who has bradycardia B. Lowering intraocular pressure in patients with glaucoma C. Inhibiting muscular activity in the bladder D. Preventing salivation and sweating

B. Lowering intraocular pressure in patients with glaucoma Cholinergic drugs stimulate the pupil to constrict (miosis), thus decreasing intraocular pressure.

What is the goal of pharmacologic therapy in treating Parkinson's disease? A) Increase the amount of acetylcholine at the presynaptic neurons. B) Decrease the amount of dopamine available in the substantia nigra. C) Balance cholinergic and dopaminergic activity in the brain. D) Block dopamine receptors in both presynaptic and postsynaptic neurons.

C) Balance cholinergic and dopaminergic activity in the brain. Parkinson's disease results from a decrease in dopaminergic (inhibitory) activity, leaving an imbalance with too much cholinergic (excitatory) activity. By increasing dopamine, the neurotransmitter activity becomes more balanced and symptoms become controlled.

Which antiparkinson drug causes an increase in the levels of dopaminergic stimulation in the central nervous system and therefore allows a decreased dose of other medications? A) levodopa B) carbidopa C) selegiline D) diphenhydramine

C) Selegiline (Eldepryl) Selegiline is a selective monoamine oxidase (MAO) B inhibitor that has been shown to cause an increase in the levels of dopaminergic stimulation in the CNS and thus allow the dose of levodopa to be decreased.

A client with a history of medication noncompliance is receiving outpatient treatment for chronic undifferentiated schizophrenia. The physician is most likely to prescribe which medication for this client? A) chlorpromazine (Thorazine) B) imipramine (Tofranil) C) lithium carbonate (Lithane) D) fluphenazine decanoate (Prolixin Decanoate)

D) fluphenazine decanoate (Prolixin Decanoate) Fluphenazine decanoate is a long-acting antipsychotic agent given by injection. Because it has a 4-week duration of action, it's commonly prescribed for outpatients with a history of medication noncompliance. Chlorpromazine, also an antipsychotic agent, must be administered daily to maintain adequate plasma levels, which necessitates compliance with the dosage schedule. Imipramine, a tricyclic antidepressant, and lithium carbonate, a mood stabilizer, are rarely used to treat clients with chronic schizophrenia.

When planning care for a burn client, the nurse would anticipate applying which topical medication? a. Lindane (Kwell) b. Minoxidil (Rogaine) c. Erythromycin (E-Mycin) d. Silver sulfadiazine (Sulfadine)

d. Silver sulfadiazine (Sulfadine) Silver sulfadiazine is a topical antiinfective drug used to treat and prevent infection in second- and third-degree burns.

A patient with Parkinson's disease discusses with the nurse experiencing insomnia recently. The patient asks the nurse, "Can I take my old prescription of benzodiazepine that is prescribed to treat my insomnia?" What does the nurse know about the use of benzodiazepines in patients taking levodopa (Larodopa)? a. Use of benzodiazepines increases the therapeutic effect of the levodopa and may result in an increase in the symptoms of Parkinson's disease. b. Use of benzodiazepines increases the therapeutic effect of the levodopa and may result in a decrease in the symptoms of Parkinson's disease. c. Use of benzodiazepines decreases the therapeutic effect of the levodopa and may result in a decrease in the symptoms of Parkinson's disease. d. Use of benzodiazepines decreases the therapeutic effect of the levodopa and may result in an increase in the symptoms of Parkinson's disease.
