#1
Which of the following drugs is commonly used as an induction agent in anesthesia?
Propofol
ExplanationCommonly used for induction due to its rapid onset and short duration.
#2
Which gas is commonly used for inhalation anesthesia?
Nitrous Oxide
ExplanationOften used as an adjunct to other anesthetics, providing analgesia and anesthesia.
#3
Which nerve is commonly blocked during a brachial plexus nerve block?
Median nerve
ExplanationProvides anesthesia to the arm, forearm, and hand.
#4
Which inhalation anesthetic agent is known for its low blood-gas solubility and rapid onset/offset of action?
Desflurane
ExplanationAllows for rapid emergence due to its low solubility in blood.
#5
Which muscle relaxant is classified as a non-depolarizing neuromuscular blocking agent?
Vecuronium
ExplanationCompetitive antagonist at the neuromuscular junction, leading to paralysis.
#6
What is the primary purpose of endotracheal intubation during anesthesia?
To secure the airway
ExplanationEnsures a patent airway, prevents aspiration, and facilitates mechanical ventilation.
#7
Which muscle relaxant is commonly used to facilitate endotracheal intubation?
Succinylcholine
ExplanationProduces rapid onset and short duration of paralysis, aiding intubation.
#8
What is the purpose of a cricothyroidotomy in emergency airway management?
To establish an emergency airway by making an incision in the cricothyroid membrane
ExplanationProvides a last resort for securing an airway in emergent situations.
#9
Which of the following is a potential complication of general anesthesia?
Hypoxemia
ExplanationA common complication due to various factors, including airway management and ventilation.
#10
What is the purpose of using a neuromuscular blockade reversal agent, such as neostigmine?
To reverse the effects of muscle relaxants
ExplanationRestores neuromuscular function postoperatively.
#11
What is the purpose of a laryngeal mask airway (LMA) in airway management?
To secure the airway without intubation
ExplanationProvides a less invasive means of maintaining a patent airway.
#12
In anesthesia, what does the term 'MAC' stand for?
Minimal Anesthetic Concentration
ExplanationThe concentration of anesthetic required to prevent movement in 50% of subjects.
#13
What is the primary goal of regional anesthesia?
To provide pain relief to a specific region of the body
ExplanationBlocks sensory nerve transmission to a specific area, offering pain relief.
#14
What does the term 'difficult airway' refer to in the context of anesthesia?
A challenging situation where airway management is complicated
ExplanationOccurs when conventional techniques may fail or be inadequate.
#15
What is the primary advantage of using a supraglottic airway device (e.g., LMA) in anesthesia?
Provides a secure airway without the need for intubation
ExplanationLess invasive than endotracheal intubation, suitable for certain procedures.
