A patient asks why the same dose of a medication may produce
different effects in different people. Which pharmacokinetic process is
most directly responsible for differences in how quickly a drug reaches
systemic circulation?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: A. Absorption
Rationale: Absorption is the process by which a medication enters the
systemic circulation. Differences in gastrointestinal function, route of
administration, blood flow, and drug formulation can alter absorption
and therefore affect the onset and intensity of medication effects.
Distribution, metabolism, and excretion occur after the drug has
entered systemic circulation.
A medication binds to a receptor and produces a physiological
response. What term describes the medication's ability to bind to that
receptor?
A. Efficacy
B. Affinity
,C. Potency
D. Clearance
Answer: B. Affinity
Rationale: Affinity refers to the strength with which a drug binds to a
receptor. Efficacy describes the maximum effect a drug can produce,
while potency refers to the amount of drug required to produce a
particular effect. Clearance refers to the removal of drug from the
body.
Which neurotransmitter is most strongly associated with mood
regulation, anxiety, sleep, and appetite?
A. Dopamine
B. Acetylcholine
C. Serotonin
D. Glutamate
Answer: C. Serotonin
Rationale: Serotonin, or 5-hydroxytryptamine (5-HT), plays important
roles in mood, anxiety, sleep, appetite, and several other physiological
processes. Many antidepressants, including SSRIs and SNRIs, increase
serotonergic neurotransmission.
Which neurotransmitter is primarily considered the major inhibitory
neurotransmitter in the central nervous system?
A. Glutamate
B. Dopamine
C. Norepinephrine
,D. GABA
Answer: D. GABA
Rationale: Gamma-aminobutyric acid (GABA) is the major inhibitory
neurotransmitter in the central nervous system. Enhancement of
GABA activity contributes to the anxiolytic, sedative, anticonvulsant,
and muscle-relaxing effects of benzodiazepines.
What is the primary mechanism of action of selective serotonin
reuptake inhibitors (SSRIs)?
A. Blocking serotonin reuptake at the presynaptic neuron
B. Blocking dopamine receptors
C. Increasing GABA receptor activity
D. Inhibiting monoamine oxidase
Answer: A. Blocking serotonin reuptake at the presynaptic neuron
Rationale: SSRIs inhibit the serotonin transporter, reducing serotonin
reuptake into the presynaptic neuron. This increases serotonergic
signaling in the synaptic space. Clinical antidepressant effects
generally take longer to emerge than the initial pharmacologic increase
in serotonin availability.
A patient taking sertraline reports nausea during the first week of
therapy. What is the most appropriate interpretation?
A. The patient is developing serotonin syndrome
B. Nausea can occur as an early SSRI adverse effect
C. The medication is causing acute psychosis
D. The medication must immediately be discontinued
, Answer: B. Nausea can occur as an early SSRI adverse effect
Rationale: Gastrointestinal symptoms such as nausea, diarrhea, and
abdominal discomfort are common early adverse effects of SSRIs.
They may diminish as treatment continues. Severe symptoms or
symptoms accompanied by findings such as agitation, hyperreflexia,
clonus, or significant autonomic instability require further evaluation.
Which finding is most characteristic of serotonin syndrome?
A. Severe constipation and urinary retention
B. Bradycardia and hypothermia
C. Clonus, hyperreflexia, agitation, and autonomic instability
D. Isolated increased appetite
Answer: C. Clonus, hyperreflexia, agitation, and autonomic instability
Rationale: Serotonin syndrome is associated with excessive
serotonergic activity. Important findings include agitation, diaphoresis,
hyperthermia, tremor, hyperreflexia, clonus, gastrointestinal
symptoms, and autonomic instability. Severe cases can become life-
threatening.
Which antidepressant class requires particular dietary precautions
because of potentially serious interactions with tyramine-containing
foods?
A. SSRIs
B. SNRIs
C. TCAs
D. MAOIs
