Answer to Question 1
Correct Answer: 3
Rationale 1: Serious cardiovascular adverse effects are possible with the use of succinylcholine.
Rationale 2: Neuromuscular blockers do not affect consciousness.
Rationale 3: Succinylcholine (Anectine) is a neuromuscular blocker that paralyzes muscles, including those of respiration.
Rationale 4: Succinylcholine and atropine are both cholinergic blockers, but they produce very different effects.
Global Rationale: Succinylcholine (Anectine) is a neuromuscular blocker that paralyzes muscles, including those of respiration. Serious cardiovascular adverse effects are possible with the use of succinylcholine. Neuromuscular blockers do not affect consciousness. Succinylcholine and atropine are both cholinergic blockers, but they produce very different effects.
Answer to Question 2
Correct Answer: 1
Rationale 1: In stage 3, or surgical anesthesia, the skeletal muscles become relaxed, cardiovascular and breathing activities stabilize, and eye movements slow.
Rationale 2: Paralysis of the medulla, which results in cessation of breathing, is stage 4 anesthesia, which is avoided.
Rationale 3: Heart rate and breathing become irregular in stage 2.
Rationale 4: General sensation is lost in stage 1, not stage 3.
