,### Question 1
In the patient being prescribed a stimulant for ADHD, which of the
following is true?
A. Ritalin LA will commonly be prescribed as a twice-a-day formulation
B. Effects of stimulants on cognitive function often diminish by 2-3 years
C. Weight gain, sleepiness and postural hypotension are common side effects
of methylphenidate
D. Strychnine is an acceptable second-line agent in the patient allergic to
methylphenidate
Correct Answer: B
Rationale:
Stimulants such as methylphenidate often improve cognitive function and
attention in ADHD, but evidence suggests the effects on cognition can diminish
over long-term use (2-3 years). Ritalin LA is typically dosed once daily due to
its extended-release profile, not twice daily. Methylphenidate more commonly
causes weight loss and insomnia rather than weight gain or sleepiness.
Strychnine is toxic and not used clinically for ADHD.

### Question 2
Prophylaxis of cluster headache is typically managed with which of the
following?
A. Aspirin
B. Verapamil
,C. Propranolol
D. Eletriptan
Correct Answer: B
Rationale:
Verapamil, a calcium channel blocker, is the first-line prophylactic treatment of
cluster headaches. Aspirin and propranolol are more commonly used in
migraine prophylaxis, and eletriptan, a triptan, is used acutely rather than
prophylactically.

### Question 3
Benzodiazepines are considered first-line therapy for which of the
following?
A. Post-traumatic stress disorder
B. Panic disorder
C. Social anxiety disorder
D. Generalized anxiety disorder
E. None of the above
Correct Answer: B
Rationale:
, Benzodiazepines can provide rapid relief for panic disorder and are
considered first-line for acute management. However, for long-term
management and other anxiety disorders such as PTSD, GAD, and social
anxiety disorder, SSRIs and CBT are preferred. Benzodiazepines have a risk of
dependence.

### Question 4
Your patient is taking Oxycodone for pain. Select the true statement
regarding this drug:
A. An overdose may be treated with Clonidine
B. Tolerance/physical dependence may occur with prolonged use
C. Blurred vision may occur in daylight
D. Diarrhea is a common side effect
E. None of the above
Correct Answer: B
Rationale:
Opioid analgesics like oxycodone cause tolerance and physical dependence
with long-term use. Overdose is treated with naloxone, not clonidine.
Constipation, not diarrhea, is a common opioid side effect. Blurred vision is
not typical.
