PSY - 5.4.3 - high-potency benzodiazepine

PSY - 5.4.4 - indicated for the treatment of depression

PSY - 5.4.5 - indicated for the short-term treatment (max. 2 weeks) of severe insomnia

Answer 3

ANSWER
PSY - 5.4.1 - its antagonist is flumazenil - C)

PSY - 5.4.2 - its elimination half-life is app. 30-40 hours - A)

PSY - 5.4.3 - high-potency benzodiazepine - A)

Question 4

PSY - 5.5
How is this clinical syndrome called?
A 35-year-old woman has been taking 0.5 mg alprazolam 3 times a day for her anxiety symptoms for 3 months. As she has recovered and fears that becomes dependent, stops taking medication. Then, anxiety symptoms come back in a more severe form and sleep disturbances occur.
A) Benzodiazepine withdrawal
B) Rebound phenomenon
C) Relapse
D) Panic disorder

Answer 4

ANSWER
B) Rebound phenomenon
EXPLANATION
The presence of anxiety symptoms more severe than the original symptoms refers to rebound phenomenon (and not to relapse) due to the sudden discontinuation of medication. Other symptoms referring to withdrawal (sweating, tremor, tachycardia) are not present.

Question 5

PSY - 5.6
Which of the following treatment options would you use in this case?
A 35-year-old woman has been taking 0.5 mg alprazolam 3 times a day for her anxiety symptoms for 3 months. As she has recovered and fears that becomes dependent, stops taking medication. Then, anxiety symptoms come back in a more severe form and sleep disturbances occur.
1) Readministration of the original dose of alprazolam and then slow dose reduction (10-25% weekly).
2) Switch to another benzodiazepine with longer elimination half-life (e.g. clonazepam) and then slow dose reduction.
3) Psychoeducation and teaching of relaxing methods (e.g. autogenic training).
4) Readministration of alprazolam and initiation of an SSRI or dual-action antidepressant for the long-term treatment of anxiety disorder and then slow dose reduction and discontinuation of benzodiazepine.

A) only the 1st, 2nd and 3rd answers are correct
B) only the 1st and 3rd answers are correct
C) only the 2nd and 4th answers are correct
D) only the 4th answer is correct
E) all of the answers are correct

Answer 5

ANSWER
A) only the 1st, 2nd and 3rd answers are correct
EXPLANATION
As it is rebound phenomenon, the initiation of long-term treatment is not indicated. Rebound symptoms can be prevented with slower dose reduction or the administration of another agent with longer half-life. Relaxing methods can help to reduce the present symptoms. Psychoeducation can help the patient to know the effective use and the risks of sudden discontinuation of a medication.

Question 6

B) the therapeutic range and toxic lithium levels are very close
C) lithium is excreted rapidly form the body
D) lithium is more of a salt, rather than a medication
E) none of the statements above

Answer 8

ANSWER
B) the therapeutic range and toxic lithium levels are very close
EXPLANATION
The regular monitoring of blood lithium concentration. is necessary because the therapeutic range and toxic concentrations are very close, higher than optimal doses or any type of dysfunction of the body fluid balance can lead to toxic lithium levels and serious adverse events.

Question 9

PSY - 5.10
Toxic conditions caused by tricyclic antidepressants resemble this type of intoxication the most:
A) amphetamine intoxication
B) atropine intoxication
C) intoxication with barbiturates
D) barbiturate withdrawal syndrome

Question 16

PSY - 5.18
Selective serotonin reuptake inhibitor (SSRI) molecules have less severe side effects than most of the classic antidepressants, except in the case of:

A) only the 1st, 3rd and 5th answers are correct
B) only the 2nd and 4th answers are correct

SSRIs hardly have any side effects, apart from the side effects related to serotonin (nausea, sexual dysfunction, paraesthesia). Compared to tricyclics they only block muscarinic acetylcholine receptors and alpha1 adrenergic receptors to a very small extent, therefore they don’t cause delirium, cognitive dysfunction, blurred vision, dry mouth, dysuria, or orthostatic hypotension.

Question 17

Question 23

PSY - 5.25
What is the pharmacological base of the therapeutic effect of typical antipsychotics?
A) They are agonists of dopamine receptors in the mesolimbic pathway (excitement).
B) They are antagonists of dopamine receptors in the nigrostriatal pathway (inhibition).
C) They are antagonists of dopamine receptors in the tuberoinfundibular pathway (inhibition).
D) They are antagonists of dopamine receptors in the mesolimbic pathway (inhibition).
E) They are antagonists of dopamine receptors in the mesocortical pathway (inhibition).

Answer 23

ANSWER
D) They are antagonists of dopamine receptors in the mesolimbic pathway (inhibition).
EXPLANATION
According to the dopamine hypothesis of schizophrenia there is an increased dopaminergic neurotransmission in the limbic system and there is a decreased dopaminergic neurotransmission in the prefrontal cortex. The former accounts for the positive symptoms whereas the latter accounts for the negative and cognitive ones. The therapeutic effect of typical antipsychotics results from the blockade of dopaminergic receptors in the mesolimbic pathway. Inhibition of the nigrostriatal and the tuberoinfundibular pathways is responsible for adverse effects.

Question 24

PSY - 5.27
The following antipsychotic is a partial agonist at the dopamine D2 receptor:
A) clozapine
B) haloperidol
C) aripiprazole
D) risperidone
E) olanzapine

Question 33

PSY - 5.37
Which therapeutic intervention is contraindicated in this case?
A young man was involuntarily admitted to a closed psychiatric hospital ward. He was extremely agitated and excited. He reported command hallucinations which made him feel intensely anxious. 10 mg of haloperidol (IM) was administered as short-term treatment, later he was given 3x4 mg (solution) of haloperidol daily. Following a transient improvement of 3 days, he reported muscular discomfort, relentless pace, intensifying agitation, insomnia despite drowsiness.
A) decreasing the dosage of haloperidol
B) administering a beta blocker
C) giving clonazepam as adjuvant treatment
