Answer to Question 1

Correct Answer: 4

Rationale 1: Botulinum toxin type A (Botox, Dysport) and botulinum toxin type B (Myobloc) are direct-acting antispasmodics.
Rationale 2: Botulinum toxin type A (Botox, Dysport) and botulinum toxin type B (Myobloc) are direct-acting antispasmodics.
Rationale 3: Botulinum toxin type A (Botox, Dysport) and botulinum toxin type B (Myobloc) are direct-acting antispasmodics.
Rationale 4: Botulinum toxin type A (Botox, Dysport) and botulinum toxin type B (Myobloc) are direct-acting antispasmodics.

Global Rationale: Botulinum toxin type A (Botox, Dysport) and botulinum toxin type B (Myobloc) are direct-acting antispasmodics. They are not peripherally acting antispasmodics, indirect-acting antispasmodics, or centrally acting antispasmodics.

Answer to Question 2

Correct Answer: 1, 2, 3

Rationale 1: Vecocuronium (Norcuron) is a nondepolarizing blocking agent.
Rationale 2: Atracurium (Tracrium) is a nondepolarizing blocking agent.
Rationale 3: Doxacurium ((Nuromax) is a nondepolarizing blocking agent.
Rationale 4: Succinylcholine chloride (Anectine, Quelicin) is incorrect because it is a depolarizing blocker.
Rationale 5: Diazepam (Valium) is incorrect because it is not a nondepolarizing blocking agent, it is a benzodiazepine.

Succinylcholine chloride (Anectine, Quelicin) is incorrect because it is a depolarizing blocker. Diazepam (Valium) is incorrect because it is not a nondepolarizing blocking agent, it is a benozdiazepine.
