Question 1 of 5
Which of the following drugs would be useful to treat the patient's condition of repeated head jerking, blinking, and grimacing?
Correct Answer: B
Rationale: Aripiprazole is an antipsychotic medication that is commonly used to treat symptoms of
Tourette syndrome, which includes tics like head jerking, blinking, and grimacing. Fluoxetine, clonazepam, naltrexone, and imipramine are not typically used for treating tics associated with
Tourette syndrome.
Question 2 of 5
Regarding GABA, which statement is false?
Correct Answer: A
Rationale: GABA receptor blockers typically have proconvulsant activity rather than anticonvulsant effects.
Question 3 of 5
Trichloroethanol is the active metabolite of:
Correct Answer: D
Rationale: Chloral hydrate (choice
D) is metabolized to trichloroethanol, which depresses the CNS, inducing sedation. Morphine (choice
A) metabolizes to active compounds like morphine-6-glucuronide, not trichloroethanol. Clorazepate (choice
B) becomes desmethyldiazepam, a benzodiazepine. Phenobarbitone (choice
C) is a barbiturate, not metabolized to trichloroethanol. This identifies Chloral hydrate's metabolic pathway, key for its hypnotic use.
Question 4 of 5
The following receptors are affected by antipsychotic drugs EXCEPT:
Correct Answer: C
Rationale: Antipsychotics (e.g., haloperidol) block central D2 (choice
A) and 5-HT2 receptors (choice
B) for efficacy, and muscarinic receptors (choice
D) peripherally, causing side effects. Peripheral H2 receptors (choice
C), involved in gastric acid secretion, aren't significantly affected; H1 antagonism occurs instead. This exception clarifies antipsychotic receptor profiles.
Question 5 of 5
Which one of the following drugs is not useful in dysmenorrhea?
