NURS 3365 MAIN EXAMINATION 2026 SET QUESTIONS
AND ANSWERS RATED A+
✔✔A patient who is newly diagnosed with Parkinson's disease and beginning
medication therapy with enta- capone (Comtan), a COMT inhibitor, asks the nurse,
"How soon will improvement occur?" What is the nurse's best response?
a. "That varies from patient to patient."
b. "You should discuss that with your physician."
c. "You should notice a difference in a few days."
d. "It may take several weeks before you notice
any degree of improvement." - ✔✔"You should notice a difference in a few days."
✔✔A patient asks the nurse why a second drug is given with his drugs for Parkinson's
disease. The nurse notes that this drug, an anticholinergic, is given to control or
minimize which symptoms? (Select all that apply.)
a. Drooling
b. Constipation
c. Muscle rigidity
d. Bradykinesia
e. Dry mouth - ✔✔Drooling
Muscle rigidity
✔✔The nurse is providing teaching on COMT inhibitors to a patient with a new
prescription. The nurse will be sure to educate the patient on the possibility of which
adverse effect?
a. Dizziness
b. Urine discoloration
c. Leg edema
d. Visual changes - ✔✔Urine discoloration
✔✔Carbidopa-levodopa (Sinemet) is prescribed for a patient with Parkinson's disease.
The nurse will inform the patient of which possible adverse effects? (Select all that
apply.)
a. Palpitations
b. Insomnia
c. Hypotension
d. Urinary frequency
e. GI distress - ✔✔Palpitations
Hypotension
GI distress
,✔✔The medication order reads: "Give benztropine (Cogentin) 2.5 mg PO every
morning." The medication is available in 1-mg tablets. How many tablets will the nurse
administer? - ✔✔2.5 tablets
✔✔Mr. H. is about to have levodopa added to his carbi-dopa treatment regimen.
a. Why must dopamine be administered in the
form of levodopa?
b. What problems are avoided when carbidopa is
given with levodopa?
c. How does the carbidopa work when given with
levodopa? - ✔✔Dopamine must be given in this form because exogenously
administered dopamine cannot pass through the blood-brain barrier; levodopa can.
The addition of carbidopa avoids the high periph- eral levels of dopamine and unwanted
side effects induced by the very large dosages of levodopa necessary when the drug is
given alone.
Carbidopa does not cross the blood-brain barrier and thus prevents levodopa
breakdown in the periphery. This, in turn, allows levodopa to reach and cross the blood-
brain barrier. Once in the brain, the levodopa is then broken down to dopa- mine, which
can be used directly.
✔✔The nurse is reviewing the use of bethanechol (Urecholine) in a patient who is
experiencing postoperative urinary reten- tion. Which statement best describes the
mechanism of action of bethanechol?
a It causes decreased bladder tone and motility.
b It causes increased bladder tone and motility.
c It increases the sensation of a full bladder.
d It causes the sphincters in the bladder to become tighter. - ✔✔It causes increased
bladder tone and motility.
✔✔The family of a patient who has recently been diagnosed with Alzheimer's disease is
asking about the new drug prescribed to treat this disease. The patient's wife says, "I'm
so excited that there are drugs that can cure this disease! I can't wait for him to start
treatment." Which reply from the nurse is appropriate?
a "The sooner he starts the medicine, the sooner it can have this effect."
b "These effects won't be seen for a few months."
c "These drugs do not cure Alzheimer's disease. Let's talk about what the physician said
to expect with this drug
therapy."
d "His response to this drug therapy will depend on how far
, along he is in the disease process." - ✔✔"These drugs do not cure Alzheimer's disease.
Let's talk about what the physician said to expect with this drug
therapy."
✔✔The nurse is giving a dose of bethanechol (Urecholine) to a
postoperative patient. The nurse is aware that contraindications to bethanechol include:
a bladder atony.
b peptic ulcer.
c urinary retention.
d hypothyroidism. - ✔✔Peptic ulcer
✔✔A patient took an accidental overdose of a cholinergic drug
while at home. He comes to the emergency department with severe abdominal
cramping and bloody diarrhea. The nurse expects that which drug will be used to treat
this patient?
a atropine (generic)
b physostigmine (Antilirium)
c bethanechol (Urecholine)
d phentolamine (Regitine) - ✔✔Atropine
✔✔The nurse is reviewing the orders for a newly admitted patient and sees an order for
edrophonium (Tensilon). The nurse expects that this drug is ordered for which reason?
a To reduce symptoms and delay the onset of Alzheimer's
disease
b To treat the symptoms of myasthenia gravis
c To aid in the diagnosis of myasthenia gravis
d To reverse the effects of nondepolarizing neuromuscular
blocking drugs after surgery - ✔✔To aid in the diagnosis of myasthenia gravis
✔✔When giving intravenous cholinergic drugs, the nurse must watch for symptoms of a
cholinergic crisis, such as: (Select all that apply.)
a peripheral tingling.
b hypotension.
c dry mouth.
d syncope.
e dyspnea.
f tinnitus. - ✔✔Hypotension
Syncope
Dyspnea
