ANSWERS| COMPLETE STUDY GUIDE | UPDATED VERSION
1. The nurse recognizes that beta2 agonists work by way of which action?
Promoting bronchodilation
Improving cardiac contractility
Increasing heart rate
Decreasing blood pressure
2. What is the primary effect of administering alpha-adrenergic antagonists?
Vasodilation
Bronchoconstriction
Increased blood pressure
Increased heart rate
3. What is a key characteristic of catecholamines in terms of their
administration?
They are primarily used for long-term management of chronic
conditions.
They can be administered orally without any issues.
They often require continuous infusion to be effective.
They have minimal side effects compared to noncatecholamines.
4. Describe the role of Donepezil in the treatment of Alzheimer's Disease.
Donepezil is a beta-blocker used to manage hypertension in
Alzheimer's patients.
, Donepezil is an acetylcholinesterase inhibitor that helps improve
cognitive function by increasing levels of acetylcholine in the brain.
Donepezil is an antipsychotic that treats behavioral symptoms in
Alzheimer's patients.
Donepezil is a dopamine agonist that enhances mood and reduces
anxiety.
5. The nurse is reviewing information on medications to be used in children with
respiratory distress. The nurse notes that medication that stimulates beta2
receptors induce:
Corticosteroids
Leukotriene modifiers
Bronchodilators
Mast cell stabilizers
6. If a patient presents with atropine toxicity characterized by confusion and
hallucinations, what would be the most appropriate initial treatment?
Administer diazepam
Increase the dose of atropine
Administer physostigmine
Provide supportive care only
7. A 72-year-old woman with Parkinson's disease has been taking pramipexole
for several months. Her daughter noticed that she is exhibiting some
compulsive behaviors recently and is concerned that her disease is getting
worse. Which of the following would you tell her?
compulsive behaviors are a common adverse effect of dopamine
agonists such as pramipexole
, behavioral problems usually improve when the dose of pramipexole is
reduced
behavioral problems usually improve when pramipexole is stopped
all of the above
8. What is the primary use of phentolamine in clinical practice?
To enhance the effects of adrenergic agonists.
To induce sedation in patients.
To relieve pain during surgical procedures.
To treat hypertension and manage pheochromocytoma.
9. Which medication has the lowest potential for abuse?
Short-acting mixed amphetamine salts
Amphetamine sulfate liquid suspension
Short-acting methylphenidate
Lisdexamfetamine (Vyvanse)
10. A female patient with a seizure disorder who is taking birth control pills is
prescribed valproic acid (Depakote). What must the nurse be sure to include
in this patient's teaching plan?
"Be sure to change positions slowly when getting out of bed."
"Do not drive a car until you know how this drug will affect you."
"Avoid consumption of grapefruit or grapefruit juice."
"Plan to use another form of contraception."
, 11. Describe the role of ondansetron in the management of nausea and vomiting
for patients on apomorphine.
Ondansetron is a dopamine agonist that treats Parkinson's disease
symptoms.
Ondansetron is a serotonin antagonist that helps alleviate nausea
and vomiting associated with apomorphine treatment.
Ondansetron is used to enhance the absorption of apomorphine in
the gastrointestinal tract.
Ondansetron increases dopamine levels to counteract the effects of
apomorphine.
12. What is the primary class of drug administered to manage premature labor in
pregnant patients?
Beta 2 agonist
Alpha 1 agonist
Beta 2 antagonist
Anticholinergic drugs
13. If a patient with biliary colic is not responding to ibuprofen for pain
management, what should the nurse consider as the next step in patient
care?
Switch to a different NSAID without a prescription.
Increase the dose of ibuprofen immediately.
Administer a second dose of ibuprofen without consulting anyone.
Consult the healthcare provider for alternative pain management
options.
