Question 1 of 5
Compared with other antidepressant drugs, mirtazapine has the distinctive ability to act as an antagonist of
Correct Answer: A
Rationale: Mirtazapine enhances norepinephrine and serotonin release by blocking presynaptic alpha2 receptors.
Question 2 of 5
A 38-year-old woman presents to the ophthalmologist for a routine eye examination. She is given intraocular pilocarpine. She was supposed to be administered two drops in each to dilate the eyes for the examination. Unfortunately, the eyedrops were administered by a new technician who inadvertently administered 10 drops of pilocarpine in each eye. Which of the following agents should be immediately given to the patient?
Correct Answer: A
Rationale: Atropine, an anticholinergic agent, can counteract the effects of excessive pilocarpine, which is a cholinergic agonist, by blocking muscarinic receptors.
Question 3 of 5
Which drug most likely enhanced the action of vecuronium in the 66-year-old woman undergoing emergency surgery following a car accident?
Correct Answer: B
Rationale: Darifenacin, a muscarinic receptor antagonist used for urinary tract infections, may enhance the action of vecuronium by reducing the risk of cholinergic side effects, such as bradycardia or bronchoconstriction, associated with muscle relaxants. Gentamicin, Timolol, Latanoprost, and Lovastatin are unlikely to have a significant impact on the action of vecuronium in this context.
Question 4 of 5
A 21-year-old male has recently begun pimozide therapy for Tourette's disorder. His parents bring him to the emergency department. They describe that he has been having “different appearing tics†than before, such as prolonged contraction of the facial muscles. While being examined, he experiences opsichotomus (type of extrapyramidal spasm of the body in which the head and heels are bent backward and the body is bowed forward). Which of the following drugs would be beneficial in reducing these symptoms?
Correct Answer: A
Rationale: Benztropine, an anticholinergic agent, is used to treat extrapyramidal symptoms like dystonia caused by antipsychotic medications.

Buspirone is:
Correct Answer: D
Rationale: Buspirone (choice D), a 5-HT1A partial agonist, treats anxiety without sedation (choice A), isn't for insomnia (choice B), and has a slow onset (choice C incorrect), taking weeks. Its anxiolytic action offers a non-addictive alternative to benzodiazepines.
