Q1 QUESTION 1 OF 140
Pyridostigmine
CORRECT ANSWER
tx for myasthenia gravis - acetylcholinesterase inhibitor
overmedication leads to excessive cholinergice stimulation = bradycardia as a warning sign
under-treatment shows up as worsening weakness requiring dose adjustment
RATIONALE
Pyridostigmine is an acetylcholinesterase inhibitor used to treat myasthenia gravis by increasing acetylcholine at the neuromuscular
junction, and its therapeutic effect is titrated based on improvements in muscle strength, with bradycardia signaling over-treatment
and excessive cholinergic stimulation. The key principle tested is the pharmacodynamics of acetylcholinesterase inhibitors and their
clinical application in managing neuromuscular disorders.
Q2 QUESTION 2 OF 140
What is a common treatment for peripheral neuropathy?
CORRECT ANSWER
Tricyclic antidepressants such as amitriptyline.
RATIONALE
Tricyclic antidepressants, like amitriptyline, are a common treatment for peripheral neuropathy due to their ability to modulate
neurotransmitter pathways involved in pain perception. This addresses the maladaptive neuroplasticity and hyperexcitability
characteristic of neuropathic pain.
Q3 QUESTION 3 OF 140
What are some anticholinergic side effects of amitriptyline?
CORRECT ANSWER
Dry mouth, constipation, blurred vision, urinary retention, and drowsiness.
RATIONALE
Amitriptyline blocks muscarinic acetylcholine receptors, leading to reduced parasympathetic stimulation and resulting in
anticholinergic effects like dry mouth, constipation, blurred vision, urinary retention, and drowsiness. This demonstrates the principle
of receptor antagonism causing predictable physiological sequelae.

, Q4 QUESTION 4 OF 140
How does amitriptyline help with pain in peripheral neuropathy?
CORRECT ANSWER
By increasing levels of serotonin and norepinephrine in the central nervous system.
RATIONALE
Amitriptyline's analgesic effect in peripheral neuropathy stems from its inhibition of serotonin and norepinephrine reuptake, thereby
enhancing descending inhibitory pain pathways in the central nervous system. This mechanism modulates nociception by increasing
neurotransmitter availability in the synaptic cleft.
Q5 QUESTION 5 OF 140
Why is amitriptyline often taken at bedtime?
CORRECT ANSWER
Because of its sedating properties, to improve sleep in patients with neuropathic pain.
RATIONALE
Amitriptyline's anticholinergic and antihistaminergic effects cause significant sedation, making bedtime administration beneficial for
patients experiencing pain-related insomnia. This leverages the drug's side effect to provide a therapeutic benefit by promoting
sleep.
Q6 QUESTION 6 OF 140
What are some alternative treatments for peripheral neuropathy?
CORRECT ANSWER
Gabapentin, pregabalin, and duloxetine.
RATIONALE
Gabapentin and pregabalin are anticonvulsants that modulate voltage-gated calcium channels, while duloxetine is a serotonin-
norepinephrine reuptake inhibitor; both mechanisms reduce neuropathic pain signaling. The key underlying concept is
pharmacotherapy targeting specific neurotransmitter pathways involved in pain transmission.
Q7 QUESTION 7 OF 140
Page 3
, Why might amitriptyline be limited in use for older adults?
CORRECT ANSWER
Due to its side effects such as drowsiness and urinary retention.
RATIONALE
Amitriptyline's anticholinergic and sedative properties can exacerbate common age-related comorbidities like cognitive impairment
and benign prostatic hyperplasia, leading to increased risks of falls and urinary retention. This highlights the importance of
considering a medication's side effect profile in the context of geriatric pharmacotherapy.
Q8 QUESTION 8 OF 140
bathanicol-used for?
CORRECT ANSWER
urinary retention
be cautious with underlying asthma as it can trigger an asthma attack
RATIONALE
Bethanechol is a cholinergic agonist that stimulates muscarinic receptors in the bladder detrusor muscle, promoting contraction and
relieving urinary retention. Its parasympathomimetic effects can also constrict bronchial smooth muscle, necessitating caution in
patients with asthma.
Q9 QUESTION 9 OF 140
topiramate se
CORRECT ANSWER
unable to regulate body temp or sweat
forgetfulness
RATIONALE
Topiramate can impair thermoregulation, leading to an inability to regulate body temperature or sweat, and can also cause cognitive
side effects like forgetfulness. This highlights the drug's potential impact on both autonomic function and central nervous system
processes.
