Question 1 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 2 of 5
Which of the following was most likely the primary reason for the use of cisatracurium instead of tubocurarine in this patient?
Correct Answer: C
Rationale: The primary reason for using cisatracurium instead of tubocurarine in this patient is likely due to propofol induction, as cisatracurium is often preferred with propofol due to their compatibility. Liver or renal insufficiency or advanced age would not specifically dictate the choice between cisatracurium and tubocurarine. Diazepam administration is not directly related to the choice between these two neuromuscular blocking agents.

Question 5 of 5
Which of the following drugs was most likely prescribed for the 12-year-old girl with refractory absence seizures?
Correct Answer: B
Rationale: In this case, the neurologist decided to add a second-generation antiepileptic drug that blocks voltage-gated Na+ and Ca2+ channels and may inhibit the synaptic release of glutamate. Among the choices, Lamotrigine fits this description as it is known to block voltage-gated sodium channels, making it the most likely drug prescribed for the patient.
