  5. All of the above

Show answer
Correct Option:
Explanation:

The major classes of psychopharmacological agents include antipsychotics, antidepressants, anxiolytics, and mood stabilizers.

What is the primary mechanism of action of typical antipsychotics?

  1. Blockade of dopamine D2 receptors

  2. Blockade of serotonin 5-HT2A receptors

  3. Blockade of norepinephrine alpha-1 receptors

  4. Blockade of GABA-A receptors

  5. Blockade of NMDA receptors

Show answer
Correct Option:

Explanation:

Haloperidol is an example of a typical antipsychotic.

What is the primary mechanism of action of atypical antipsychotics?

  1. Blockade of dopamine D2 receptors

  2. Blockade of serotonin 5-HT2A receptors

  3. Blockade of norepinephrine alpha-1 receptors

  4. Blockade of GABA-A receptors

  5. Blockade of NMDA receptors

Show answer
Correct Option:
Explanation:

Atypical antipsychotics primarily work by blocking serotonin 5-HT2A receptors in the brain.

Which of the following is an example of an atypical antipsychotic?

  1. Haloperidol

  4. Quetiapine

  5. Aripiprazole

Show answer
Correct Option:
Explanation:

Olanzapine is an example of an atypical antipsychotic.

What is the primary mechanism of action of antidepressants?

  1. Inhibition of serotonin reuptake

  2. Inhibition of norepinephrine reuptake

  3. Inhibition of dopamine reuptake

  4. Inhibition of GABA reuptake

  5. Inhibition of glutamate reuptake

Show answer
Correct Option:
Explanation:

Antidepressants primarily work by inhibiting the reuptake of serotonin in the brain.

Which of the following is an example of an antidepressant that inhibits serotonin reuptake?

  1. Fluoxetine

  2. Venlafaxine

  3. Bupropion

  4. Mirtazapine

  5. Trazodone

Show answer
Correct Option:
Explanation:

Fluoxetine is an example of an antidepressant that inhibits serotonin reuptake.

What is the primary mechanism of action of anxiolytics?

  1. Potentiation of GABA-A receptor activity

  2. Inhibition of serotonin reuptake

  3. Inhibition of norepinephrine reuptake

  4. Inhibition of dopamine reuptake

  5. Inhibition of glutamate reuptake

Show answer
Correct Option:
Explanation:

Anxiolytics primarily work by potentiating the activity of GABA-A receptors in the brain.

Which of the following is an example of an anxiolytic that potentiates GABA-A receptor activity?

  1. Diazepam

  2. Buspirone

  3. Propranolol

  4. Hydroxyzine

  5. Pregabalin

Show answer
Correct Option:
Explanation:

Diazepam is an example of an anxiolytic that potentiates GABA-A receptor activity.

What is the primary mechanism of action of mood stabilizers?

  1. Inhibition of voltage-gated sodium channels

  2. Inhibition of voltage-gated calcium channels

  3. Inhibition of voltage-gated potassium channels

  4. Inhibition of voltage-gated chloride channels

  5. Inhibition of voltage-gated glutamate channels

Show answer
Correct Option:
Explanation:

Mood stabilizers primarily work by inhibiting voltage-gated calcium channels in the brain.

Which of the following is an example of a mood stabilizer that inhibits voltage-gated calcium channels?

  1. Lithium

  2. Valproate

  3. Carbamazepine

  4. Lamotrigine

  5. Topiramate

Show answer
Correct Option:
Explanation:

Valproate is an example of a mood stabilizer that inhibits voltage-gated calcium channels.
