1. Phenothiazines, like chlorpromazine, are used to treat___________.
Correct Answer: Psychosis
Expert Rationale: Phenothiazines such as chlorpromazine are first-generation
antipsychotic medications used primarily to manage psychotic disorders such as
schizophrenia. These medications work by blocking dopamine receptors in the brain, which
helps decrease hallucinations, delusions, and agitation associated with psychosis.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
2. A1 Blockers have __________ as an adverse effect.
Correct Answer: Hypotension
Expert Rationale: Alpha-1 blockers cause vasodilation by relaxing smooth muscle in blood
vessels. Excessive vasodilation can result in orthostatic hypotension, dizziness, and
syncope, especially when the patient changes positions quickly.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
,3. Which drug works on the hypothalamus to reduce fevers?
Correct Answer: Acetaminophen (Tylenol)
Expert Rationale: Acetaminophen acts on the hypothalamic heat-regulating center to
reduce fever. It is commonly used for mild pain and fever reduction and does not have the
anti-inflammatory effects associated with NSAIDs.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
4. Which drugs work to reduce symptoms of BPH?
Correct Answer: Alpha-1 blockers such as tamsulosin (Flomax) and 5-alpha reductase
inhibitors such as Proscar.
Expert Rationale: Alpha-1 blockers relax smooth muscle in the bladder neck and prostate
to improve urine flow, while 5-alpha reductase inhibitors reduce prostate enlargement over
time by decreasing dihydrotestosterone levels.
DIF: Application

OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
5. Benzos and antihistamines work to reduce__________.
Correct Answer: Anxiety
Expert Rationale: Benzodiazepines and certain antihistamines have sedative properties
that reduce central nervous system stimulation. These medications are commonly used to
manage anxiety, promote relaxation, and decrease agitation.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
,TOP: Assessment / Nursing Process Step: Evaluation
6. Clients with asthma or COPD should not receive __________________________.
Correct Answer: Non-selective beta blockers
Expert Rationale: Non-selective beta blockers block both beta-1 and beta-2 receptors.
Blocking beta-2 receptors in the lungs may cause bronchoconstriction and worsen
respiratory conditions such as asthma or COPD.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
7. Beta blocker drugs all end in what three letters?
Correct Answer: LOL
Expert Rationale: Most beta blockers end in the suffix “-lol,” which helps identify them
pharmacologically. Examples include propranolol, atenolol, and carvedilol.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
8. The dopaminergic drug for Parkinson's disease is _____________.
Correct Answer: Carbidopa-levodopa (Sinemet)
Expert Rationale: Carbidopa-levodopa increases dopamine levels in the brain, improving
motor symptoms such as rigidity, tremors, and bradykinesia associated with Parkinson’s
disease.
DIF: Application
REF: Pharmacology / Nursing Process
, OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
9. Migraine headaches and glaucoma can be treated with B1 blockers because
they ___________________.
Correct Answer: Decrease pressure
Expert Rationale: Beta blockers reduce intraocular pressure in glaucoma and may also
decrease vascular pressure and sympathetic stimulation associated with migraine
headaches.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
10. Bethanechol (Urecholine) is used for ___________.
Correct Answer: Urinary retention
Expert Rationale: Bethanechol is a cholinergic agonist that stimulates bladder muscle
contraction, making it useful for treating nonobstructive urinary retention.
DIF: Application
REF: Pharmacology / Nursing Process
OBJ: Recognize pharmacologic actions, adverse effects, and nursing implications
TOP: Assessment / Nursing Process Step: Evaluation
11. What are the adverse effects of cholinergic drugs?
Correct Answer: Syncope, hypotension, urinary frequency, and breathing difficulties
Expert Rationale: Cholinergic drugs overstimulate the parasympathetic nervous system,
leading to excessive secretions, bronchoconstriction, hypotension, and increased urinary
output.
