Study Guide, Questions, Answers & Detailed
Rationales
1. What three classes of drugs are used to treat anxiety?
a) Benzodiazepines, Beta Blockers, SSRIs
b) SSRIs, SNRIs, TCAs
c) MAOIs, TCAs, Antipsychotics
d) Benzodiazepines, Barbiturates, Z-drugs
Correct Answer: b) SSRIs, SNRIs, TCAs
Rationale: First-line treatment for anxiety disorders includes SSRIs,
SNRIs, and TCAs. These antidepressants are preferred for long-term
management of anxiety because they lack the dependency potential of
benzodiazepines. Benzodiazepines are used short-term for acute
symptom relief.
2. What two classes of drugs are used to treat the symptoms of
anxiety?
a) SSRIs and SNRIs
b) Beta Blockers and Alpha-2 Agonists
,c) Benzodiazepines and TCAs
d) MAOIs and Antipsychotics
Correct Answer: b) Beta Blockers and Alpha-2 Agonists
Rationale: Beta blockers (e.g., propranolol) help manage physical
symptoms of anxiety such as tachycardia and tremors. Alpha-2 agonists
(e.g., clonidine) reduce sympathetic nervous system activity. These are
used for symptomatic relief rather than treating the underlying anxiety
disorder.
3. What are five non-pharmacological interventions to help sleep?
(Select all that apply)
a) Alcohol
b) Brightness
c) Caffeine
d) Heat
e) Large meal before bedtime
f) Stress
g) Regular sleep schedule
Correct Answer: a, b, c, d, e, f (all are factors that NEGATIVELY affect
sleep)
, Rationale: This question addresses factors that interfere with sleep
rather than promote it. Alcohol disrupts sleep architecture; brightness
suppresses melatonin; caffeine is a stimulant; heat disrupts
thermoregulation needed for sleep; large meals cause discomfort;
stress increases arousal. Patients should AVOID these to improve sleep
hygiene.
4. What CAM is used for insomnia?
a) St. John's Wort
b) Echinacea
c) Melatonin
d) Aloe vera
Correct Answer: c) Melatonin
Rationale: Melatonin is a hormone naturally produced by the pineal
gland that regulates the sleep-wake cycle. As a complementary and
alternative medicine (CAM) supplement, it is commonly used to treat
insomnia and jet lag by promoting sleep onset.
5. What drugs are prescription melatonin?
a) Ramelteon and Tasimelteon
b) Zolpidem and Zaleplon
