Page 7 18. A nurse is caring for a client admitted to the health care facility. The client is receiving a cholinergic blocking drug as treatment for bladder overactivity. Which intervention would be most appropriate for the nurse to include as part of the client's ongoing assessment? A) Assessment of the client's medical history B) Evaluation of symptoms related to the client's diagnosis C) Monitoring of the client's vital signs every 24 hours D) Observation for behavioral changes in the client Ans: B Feedback: The nurse should evaluate the symptoms and complaints related to the client's diagnosis during the ongoing assessment of the treatment. The nurse should assess the medical history of the client before administration of the drug as part of the preadministration assessment. The vital signs of the client should be monitored regularly instead of every 24 hours. The nurse need not observe for behavioral changes in the client based on the client's diagnosis and condition. 19. A nurse is caring for a 60 -year-old client with a peptic ulcer. The client is prescribed belladonna. The nurse would closely monitor this client for which of the following? A) Disorientation B) Lightheadedness C) Blurred vision D) Mydriasis Ans: C Feedback: The nurse should monitor for blurred vision in the client after administration of the belladonna alkaloid drug. The other conditions observed are drowsiness, tachycardia, dry mouth, and urinary hesitancy. Disorientation, lightheadedness, and mydriasis are adverse reactions associated with the administration of trihexyphenidyl. 20. A nurse is teaching a client about the increased risk of heat prostration during the hot summer months related to his prescribed scopolamine therapy. The nurse determines that the teaching was successful when the client identifies which of the following as a sign of this condition? A) Dry mouth B) Fever C) Skin rash D) Urinary retention Ans: B Feedback: Signs of heat prostration include fever; tachycardia ; flushing; warm, dry skin; and mental confusion. www.testbanktank.com Page 8 21. A client with a peptic ulcer visits a health care facility. The physician has prescribed belladonna as part of the treatment. Before administering this drug, the nurse would assess which of the follo wing? A) Saliva B) Stools C) Urine pH D) Blood glucose level Ans: B Feedback: Before administering belladonna, the nurse should check the stools of the client who has a peptic ulcer along with performing additional assessments such as color and signs of occult blood. The nurse need not check saliva, urine pH, or blood glucose level. 22. A nurse is administering a choliner gic blocking drug preoperatively to a client. What intervention should the nurse perform after administering the drug to the client? A) Provide cold milk to the client. B) Raise the side rails of the bed. C) Tell the client to lie completely flat in bed. D) Provide frequent sips of water. Ans: B Feedback: The nurse should raise the side rails of the client's bed after administration of the drug. The nurse need not provide cold milk or provide frequent sips of water as fluids cannot be given after administering the drug. The client needs to remain in bed, but he or she can assume a position of comfort. There is no need to lie completely flat. 23. A nurse is caring for a client who has been prescribed belladonna for the treatment of prolonged diarrhea. Which of the following nursing interventions should the nurse perform before administering the drug? A) Check stools of the client. B) Monitor for abdominal pain. C) Assess weight of the client. D) Monitor vital signs every 2 hours. Ans: C Feedback: The nurse should assess the client's weight when caring for this client with prolonged diarrhea. The nurse should check the stools of the client who has been administered belladonna alkaloids for the treatment of peptic ulcer. The nurse need not monitor for abdominal pain or monitor the client's vital signs every 2 hours when caring for a client with diarrhea. www.testbanktank.com Page 9 24. A nurse is caring for a client receiving cholinergic blocking drug therapy. The client complains of a cotton-mouth feeling. Which of the following would be most appropriate? A) Inspect the throat for signs of an infection. B) Suggest the client avoid ingesting water before taking the drug. C) Check the oral cavity daily for soreness or ulcerations. D) Suggest the client avoid the use of ice or cold beverages. Ans: C Feedback: The nurse should check the oral cavity daily for soreness or ulcerations when caring for a client with severe mouth dryness. The nurse should encourage the client to take a few sips of water before and while taking the drug and to sip water at intervals during meals. If allowed, hard candy slowly dissolved in the mouth and frequent sips of water during the day may help relieve persistent oral dryness. There is no need to inspect the throat for infection or to avoid ice and cold beverages. 25. A client is experiencing photophobia secondary to the administration of a cholinergic blocking drug. Which of the following would be most appropriate? A) Keeping the client's room brightly lit B) Limiting the use of overhead lights C) Encouraging the client to use sunscreen D) Suggesting the client avoid watching television Ans: B Feedback: If photophobia is a problem, the patient may need to wear shaded glasses when going outside, even on cloudy days. Rooms are kept dimly lit and curtains or blinds closed to eliminate bright sunlight in the room. Those with photophobia may be more comfortabl e in a semi -darkened room, especially on sunny days. It is a good idea to use overhead lights as little as possible. Sunscreen would be appropriate for photosensitivity, not photophobia. Avoiding television would be appropriate if the client experienced mydriasis and cycloplegia. 26. A client with motion sickness is prescribed transdermal scopolamine. The nurse would instruct the client to apply the patch at which frequency? A) Every 8 hours B) Every 24 hours C) Every 48 hours D) Every 72 hours Ans: D Feedback: A scopolamine patch is applied 4 hours before travel every 3 days or every 72 hours. www.testbanktank.com Page 10 27. A nursing instructor is conducting a class for a group of nursing students about cholinergic blocking drugs.

A) Amantadine (Symmetrel) B) Bromocriptine (Parlodel) C) Biperiden (Akineton) D) Carbidopa (Lodosyn) E) Benztropine (Cogentin) Ans: A, B, D Feedback: Amantadine (Symmetrel), bromocriptine (Parlodel), and carbidopa (Lodosyn) are classified as dopaminergic drugs. Biperiden and benztropine are cholinergic blocking drugs used to treat Parkinson's disease. 3. A nurse is reviewing the medication record of several clients with Parkinson's disease. The nurse identifies which drug if included in the client's record as being classified as a catechol -O-methyltransferase (COMT) inhibitor drug? Select all that app ly. A) Amantadine (Symmetrel) B) Bromocriptine (Parlodel) C) Biperiden (Akineton) D) Entacapone (Comtan) E) Tolcapone (Tasmar) Ans: D, E Feedback: Entacapone (Comtan) and tolcapone (Tasmar) are classified as COMT inhibitors. Amantadine and bromocriptine are dopaminergic drugs. Biperiden is a cholinergic blocking drug. www.testbanktank.com Page 2 4. A nurse reviews a client's medical record for possible conditions that would contraindicate the use of carbidopa/levodopa (Sinemet). Which of the following would the nurs e identify as a contraindication? Select all that apply. A) Narrow -angle glaucoma B) Renal disease C) Hepatic disease D) Diabetes E) Use of MAOI antidepressants Ans: A, E Feedback: Carbidopa/levodopa (Sinemet ) is contraindicated in clients who have known hypersensitivity to the drug or narrow-angle glaucoma or who use MAOI antidepressants. 5. A client is prescribed carbidopa/levodopa. The nurse understands that this drug should be administered cautiously to clients with which condition? Select all that apply. A) Hyperthyroidism B) Seizure disorder C) Renal disease D) Asthma E) Peptic ulcer disease Ans: C, D, E Feedback: Carbidopa/levodopa (Sinemet ) is used cautiously in clients with cardiovascular or pulmonary disease (asthma), peptic ulcer disease, renal or hepatic disease, and psychosis. 6. A nurse administering carbidopa/levodopa (Sinemet) to a client should monitor the client for decreased e ffects of carbidopa/levodopa when which of the following medications are initiated? Select all that apply. A) Phenytoin (Dilantin) B) Amitriptyline (Elavil) C) Zonisamide (Zonegran) D) Ibuprofen (Motrin) E) Meperidine (Demerol) Ans: A, C Feedback: A nurse administering carbidopa/levodopa (Sinemet) to a client should monitor the client for decreased effects of carbidopa/levodopa (Sinemet) when anticonvulsants, like phenytoin and zonisamide, are initiated. www.testbanktank.com Page 3 7. The nurse would be alert for a client taking benztropine (Cogentin) to have increased anticholinergic effects if which of the following medications are also started? Select all that apply. A) Amantadine (Symmetrel) B) Quetiapine (Seroquel) C) Glycopyrrolate (Robinul) D) Perphenazine (Trilafon) E) Tiotropium (Spiriva) Ans: A, D Feedback: A client taking benztropine (Cogentin) will have increased anticholinergic effects if amantadine or phenothiazines such as perphenazine are given together. 8. The nurse understands the need for cautious administration of the prescribed entacapone to a client with which of the following? Select all that apply. A) Hypotension B) Renal dysfunction C) Hepatic dysfunction D) Diabetes E) Hypertension Ans: A, B, C, E Feedback: The nurse should cautiously administer entacapone (Comtan) to clients with hypotension, hypertension, and decreased hepatic or renal function. 9. After administering tolcapone (Tasmar ) to a client, the nurse would be alert for which of the following as a possible adverse reaction? Select all that apply. A) Orthostatic hypotension B) Renal failure C) Dyskinesia D) Dry mouth E) Anorexia Ans: A, C, E Feedback: Adverse reactions associated with tolcapone (Tasmar) include orthostatic hypotension, dyskinesia, sleep disorders, dystonia, excessive dreaming, somnolence, dizziness, nausea, anorexia, muscle cramps, and liver failure. www.testbanktank.com Page 4 10.

A) Benztropine B) Levodopa C) Carbidopa D) Tolcapone E) Entacapone Ans: B, C, E Feedback: Stalevo is a brand -name combination product that contains carbidopa, levodopa, and entacapone. 14. A nurse is caring for a client who has been prescribed pramipexole for the treatment of Parkinson's disease. From the client's medical records, the nurse underst ands that the client is taking verapamil. The nurse understands that the client is at increased risk for which effect from the interaction of the two drugs? A) Cardiac symptoms B) Agonist effectiveness C) Toxicity of both drugs D) Psychotic behavior Ans: B Feedback: The nurse should assess for an increased risk of agonist effectiveness in the client. Increased risk of cardiac symptoms and increased risk of toxicity of both drugs are the effects of the interaction of COMT inhibitors with MAOI antidepressants and adrenergic drugs. Increased risk of psychotic behavior is the effect of the interaction of cholinergic blocking drugs with halop eridol. www.testbanktank.com Page 6 15. A nurse is caring for a 55 -year-old client with Parkinson's disease who is prescribed entacapone. The nurse would monitor this client for which adverse reaction? A) Increased hand tremor B) Constipation C) Urinary retention D) Dyskinesia Ans: D Feedback: The nurse should monitor for dyskinesia, which is an adverse reaction of the COMT inhibitors, in the client. The other adverse reactions include dizziness, hyperkinesia, nausea, anorexia, diarrhea, orthostatic hypotension, sleep disorders, excessive dreaming, somnolence, and muscle cramps. A serious, and possibly fatal, adverse reaction that can occur with the administration of tolcapone, one of the COMT inhibitors, is liver failure. Increased hand tremor and constipation are adverse effects associated with the use of dopaminergic drugs. Urinary retention is an adverse reaction associated with the administration of cholinergic blocking drugs. 16. A nurse is caring for a client who has been prescribed amantadi ne for the treatment of the influenza A virus. After administration of the drug, the client complains of dry mouth. Which of the following instructions should the nurse offer the client to help relieve dry mouth? A) Instruct the client to take ice chips f requently. B) Encourage the client to take small, frequent meals. C) Instruct the client to avoid protein -rich foods. D) Stop the use of the antiparkinsonism drug by the client. Ans: A Feedback: The nurse should instruct the client to suck on ice chips or hard candy (if allowed). The nurse should also instruct the client to take frequent sips of water throughout the day and between meals. The nurse encourages the client to have small, frequent meals when the client experiences a GI disturbance and not when the client complains of dry mouth. The nurse also need not instruct the client to avoid protein- rich foods because this will not reduce the client's discomfort due to dry mouth. The nurse should stop the use of the antiparkinsonism drug when the client complains of severe nausea or vomiting and not when the client is experiencing dry mouth. If dry mouth is so severe that there is difficulty in swallowing or speaking, or if loss of appetite and weight loss occur, the dosage of the antiparkinsonism drug may be reduced but not stopped completely. www.testbanktank.com Page 7 17. A nurse is caring for a 70 -year-old client who is receiving anticholinergic drug therapy for Parkinson's disease. The nurse would be alert for the development of which of the following in this client? A) Confusion and disorientation B) Choreiform movements C) Suicidal tendencies D) Psychotic episodes Ans: A Feedback: The nurse should assess for confusion and disorientation when caring for this elderly client receiving anticholinergic drug therapy. Individuals older than 60 years frequently develop increased sensitivity to anticholinergic drugs and require careful monitoring. Lower doses may also be required in such cases. Choreiform movements, suicidal tendencies, and psychotic episodes are serious adverse reactions associated with the use of levodopa, which is a dopaminergic drug. 18. A nurse is assigned to care for a 40-year-old client with a hepatic injury that has occurred due to the administration of tolcapone. Which of the following interventions should the nurse perform when caring for this client? A) Monitor the client for signs of tactile hallucinations. B) Monitor the client for signs of dystonic movements. C) Perform regular blood tests of the client. D) Perform serum transaminase level testing every day. Ans: C Feedback: A serious and potentially fatal adverse reaction to tolcapone is hepatic injury. The nurse should, therefore, perform regular blood testing to monitor liver function of the client as prescribed. The testing of serum transaminase levels may be ordered at frequent intervals such as every 2 weeks for the first year and every 8 weeks thereafter. The nurse need not perform serum transaminase level testing every day. The nurse should monitor for signs of dystonic movements when caring for a client receiving carbidopa and levodopa, not tolcapone. The nurse should monitor for signs of tactile hallucinations when caring for an elderly client receiving tolcapone. www.testbanktank.com Page 8 19. A nurse is caring for a 70 -year-old client undergoing antiparkinsonism drug therapy. The client is prescribed pramipexole by the physician. The nurse should monitor the client's condition for the development of which of the following adverse reactions associated with the use of this drug? A) Blurred vision B) Memory loss C) Visual hallucinations D) Muscular rigidity Ans: C Feedback: The nurse should monitor the elderly client who is administered a dopamine receptor antagonist for signs of visual, auditory, or tactile hallucinations. Hallucinations occur more often in older adults than in younger adults receiving the antiparkinsonism drugs, especially when taking the dopamine receptor agonists. The incidence of hallucinations appears to increase with age. The nurse need not monitor the client's condition for signs of blurred vision, memory loss, and muscular rigidity as these conditions are not known to occur in elderly clients due to the use of dopamine receptor agonists. 20. A nurse is assigned to care for a client who is to receive a cholinergic blocking drug. The nurse obtains the history from the client. Which of the following would alert the nurse to the need for cautious administration? A) The client has a decreased liver function. B) The client has a history of hallucinations or psychosis. C) The client has a cardiovascular disease. D) The client has a pulmonary disease. Ans: A Feedback: It is important for the nurse to know if the client has decreased liver or kidney function so that the cholinergic blocking drug can be administered cautiously in the client. Other conditions in clients that require cautious use include tachycardia, cardiac arrhythmias, hypertension, hypotension, tendency toward urinary retention, and obstructive disease of the urinar y system or gastrointestinal tract. The cholinergic blocking drugs are given with caution to older adults. The nurse should use dopamine receptor agonist drugs with caution in clients with a history of hallucinations or psychosis or cardiovascular disease. The nurse should use dopaminergic drugs with caution in clients with pulmonary diseases. www.testbanktank.com Page 9 21. A nurse is caring for a client who requires antiparkinson drug therapy. The nurse confirms that which of the following conditions is absent because it would contraindicate the use of the COMT inhibitor? A) Pregnancy B) Achalasia C) Peptic ulcers D) Glaucoma Ans: A Feedback: The nurse should confirm that the client is not pregnant or lactating and that the client does not have a hypersensitivity to the drug to ensure that the use of COMT inhibitors is not contraindicated. Achalasia, peptic ulcers, and glaucoma are not conditions that are contraindications to the use of COMT inhibitors. The use of cholinergic blocking drugs is contraindicated in clients with achalasia, peptic ulcers, and glaucoma. 22. A nurse is caring for a client who has received carbidopa/levodopa. After a dministration of the first dose of the drug, the client has developed gastrointestinal disturbances. Which of the following nursing interventions would be most appropriate? A) Administer the next drug dose with milk. B) Withhold the next drug dose. C) Observe for alterations in blood pressure. D) Administer the next drug dose with meals. Ans: D Feedback: The nurse should administer the next drug dose with meals to manage gastrointestinal disturbances in a client who has been administered antiparkinsonism drugs. Withholding the next drug dose, administering the next drug dose with milk, or observing alterations in the client's blood pressure are not appropriate interventions when caring for a client who is experiencing GI disturbances with the first dose of antiparkinsonism drugs. www.testbanktank.com Page 10 23. A client with Parkinson's disease is undergoing treatment in a health care facility. Which of the following nursing interventions should the nurse perform as part of the client's ongoing assessment? A) Asse ss the client for ability to perform the daily activities. B) Observe the current mental condition of the client. C) Observe the client for various neuromuscular signs. D) Prepare a baseline for future evaluations of the client's drug therapy. Ans: C Feedback: The nurse should evaluate the client's response to drug therapy by observing the client for various neuromuscular signs to compare these observations with the data obtained during the initial physical assessment. The nurse should assess the client's ability to perform daily activities and observe the client's current mental condition before the drug is administered to the client as part of the preadministration assessment. During the preadministration assessment, before starting the drug therapy, the nurse also performs a physical assessment of the client to provide a baseline for future evaluations of drug therapy. 24. A nurse is reviewing the medical record of a client who is exhibiting Parkinson -like adverse reactions due to drug therapy. Which drugs might the nurse note in the client's record? Select all that apply. A) Antidepressants B) Conventional antipsychotics C) Lithium D) Opioids E) NSAIDs Ans: A, B, C Feedback: Drugs such as antidepressants, antiemetics, first -generation antipsychotics, lithium, and stimulants can cause symptoms similar to Parkinson's disease. Opioids and NSAIDs are not associated with Parkinson -like symptoms. www.testbanktank.com Page 11 25. A client is admitted to the health care facility with a diagnosis of Parkinson's disease. When assessing the client, which of the following would the nurse expect to find? Select all that apply. A) Slurred speech B) Erect posture C) Step-like gait D) Tremors E) Rapid, jerky movements Ans: A, D Feedback: The cardinal signs of Parkinson's disease include tremors, rigidity, and slow movement (bradykinesia). Other symptoms of Parkinson's disease include slurred speech, a mask -like and emotionless appearance of the face, and difficulty chewing and swallowing. The patient assumes a rigid, bent-forward posture and the gait becomes unsteady and shuffled. 26. After administering an antiparkinson drug to a client, the nurse assesses the effectiveness of the drug. The nurse notes that the client's slow movements have improved. The nurse documents this as an improvement in which of the following? A) Akathisia B) Bradykinesia C) Achalasia D) Choreiform movements Ans: B Feedback: Bradykinesia refers to the slow movements associated with Parkinson's disease. Akathisia refers to extreme restlessness and increased motor activity. Achalasia refers to the failure to relax, usually referring to the smooth muscle fibers of the GI tract. Choreiform movements refer to the involuntary muscular twitching of the limbs or facial muscles. www.testbanktank.com
