Why does tyramine cause a hypertensive crisis in patients taking MAOIs?
A. Tyramine directly blocks serotonin reuptake
B. MAO inhibition prevents tyramine breakdown, increasing catecholamine release
C. Tyramine decreases dopamine metabolism
D. MAOIs increase insulin resistance
Correct Answer: B
Rationale:
When MAO is inhibited, tyramine is not metabolized, leading to excess norepinephrine and epinephrine, causing a dangerous rise in blood pressure.
267
Which medication is most dangerous when taken concurrently with an MAOI?
A. Acetaminophen
B. Meperidine
C. Lithium
D. Gabapentin
Correct Answer: B. Meperidine
Rationale:

A. Naloxone
B. Phentolamine
C. Haloperidol
D. Dantrolene
Correct Answer: B. Phentolamine

A. Frontal headache with photophobia
B. Gradual onset headache relieved by rest
C. Sudden explosive occipital headache
D. Muscle rigidity and hyperreflexia
Correct Answer: C

273
Which asthma medication may precipitate hypertensive crisis when taken with MAOIs?
A. Montelukast
B. Albuterol
C. Fluticasone
D. Ipratropium
Correct Answer: B. Albuterol
Rationale:

A. Low sodium
B. Elevated creatine phosphokinase (CPK)
C. Decreased white blood cell count
D. Low liver enzymes
Correct Answer: B. Elevated CPK

A. Hematuria
B. Dehydration
C. Myoglobinuria from rhabdomyolysis
D. Acute kidney infection

A. Serotonin syndrome
B. Major depressive relapse
C. Serotonin discontinuation syndrome
D. Neuroleptic malignant syndrome
Correct Answer: C. Serotonin Discontinuation Syndrome

Abrupt discontinuation of an SSRI with FANIMA symptoms strongly indicates serotonin discontinuation syndrome, not serotonin toxicity.
293
Which symptom is most characteristic of serotonin discontinuation syndrome?
A. Hyperreflexia
B. Myoclonic jerks
C. Fatigue and lethargy
D. Severe muscle rigidity
Correct Answer: C. Fatigue and lethargy
