Phenothiazines such as chlorpromazine are primarily used to treat which condition?
A. Anxiety
B. Psychosis
C. Depression
D. Seizures
Correct Answer: B. Psychosis
Phenothiazines are first-generation antipsychotics that block dopamine receptors in the brain,
reducing hallucinations, delusions, and disorganized thinking. They are primarily indicated for
schizophrenia and other psychotic disorders.
Alpha-1 blockers commonly cause which adverse effect? A. Hypertension
B. Hypotension
C. Bradycardia
D. Hyperglycemia
Correct Answer: B. Hypotension
Alpha-1 blockers cause vasodilation of peripheral vessels, leading to decreased blood pressure,
especially orthostatic hypotension due to reduced vascular resistance.
Which medication acts on the hypothalamus to reduce fever? A. Ibuprofen
B. Acetaminophen
C. Morphine
D. Aspirin only
Correct Answer: B. Acetaminophen
Acetaminophen reduces fever by acting on the hypothalamic heat-regulating center, lowering the
set point and promoting heat loss.
,Which medications are used to treat BPH? (SATA)
A. Tamsulosin
B. Finasteride
C. Propranolol
D. Proscar
E. Atenolol
Correct Answer: A, B, D
Alpha-1 blockers (tamsulosin) relax smooth muscle in the prostate, while 5-alpha reductase
inhibitors (finasteride/Proscar) reduce prostate size.
Benzodiazepines and antihistamines are commonly used to treat which condition?
A. Infection
B. Anxiety
C. Hypertension
D. Diabetes
Correct Answer: B. Anxiety
Both drug classes produce CNS depression, reducing anxiety and promoting sedation.
Which symptoms are associated with cholinergic crisis? (SATA) A. Bronchoconstriction
B. Hypotension
C. Circulatory collapse
D. Constipation
E. Cardiac arrest
Correct Answer: A, B, C, E
Cholinergic crisis results from excessive parasympathetic stimulation causing bronchospasm,
hypotension, bradycardia, and possible respiratory failure.
Patients with asthma should avoid which medications?
A. Beta-1 selective blockers
,B. Non-selective beta blockers
C. ACE inhibitors
D. Diuretics
Correct Answer: B. Non-selective beta blockers These block beta-2 receptors causing
bronchoconstriction, worsening asthma or COPD.
Hydroxyzine (Atarax, Vistaril) and diphenhydramine (Benadryl) are classified as
which drug class? A. Antihistamines
B. Antipsychotics
C. Beta blockers
D. Anticoagulants
Correct Answer: A. Antihistamines These drugs block histamine receptors and also
reduce anxiety due to sedative effects.
Cholinergic drugs mimic which nervous system response? A. Sympathetic
B. Parasympathetic
C. Somatic
D. Endocrine
Correct Answer: B. Parasympathetic
They promote “rest and digest” functions such as decreased heart rate and increased digestion.
Beta-blockers typically end with which suffix?
A. -pril
B. -sartan
C. -lol
D. -pine
Correct Answer: C. -lol
Examples include propranolol, atenolol, and carvedilol.
, Which dopaminergic drug is used in Parkinson’s disease? A. Haloperidol
B. Levodopa-carbidopa (Sinemet)
C. Diazepam
D. Metformin
Correct Answer: B. Levodopa-carbidopa (Sinemet)
Restores dopamine levels to improve motor function in Parkinson’s disease.
Benzodiazepines are used to treat which condition? A. Anxiety
B. Infection
C. Hypertension
D. Diabetes
Correct Answer: A. Anxiety
They enhance GABA activity, producing CNS depression and anxiolytic effects.
Adrenergic drugs mimic which nervous system response?
A. Parasympathetic
B. Sympathetic
C. Endocrine
D. Immune
Correct Answer: B. Sympathetic
They produce fight-or-flight responses such as increased heart rate and blood pressure.
Cholinergic drug effects include which? (SATA)
A. Bradycardia
B. Bronchoconstriction
C. Miosis
D. Increased HR
