Which intravenous anesthetic is commonly used for induction due to its rapid onset and short duration?
Answer: Propofol
Propofol is widely used for anesthesia induction because it acts quickly and allows for a smooth recovery.
What is the primary mechanism of action of inhaled anesthetics like sevoflurane?
Answer: Enhance GABA receptor activity
Inhaled anesthetics such as sevoflurane act on the central nervous system by enhancing inhibitory neurotransmission via GABA receptors.
Which opioid analgesic is most commonly used in anesthesia for its potent pain-relieving properties?
Answer: Fentanyl
Fentanyl is a synthetic opioid that is frequently used in anesthesia due to its high potency and rapid onset.
Which drug is used to reverse the effects of neuromuscular blocking agents?
Answer: Neostigmine
Neostigmine is an acetylcholinesterase inhibitor that reverses neuromuscular blockade by increasing acetylcholine at the neuromuscular junction.
Which local anesthetic has the longest duration of action?
Answer: Bupivacaine
Bupivacaine has a longer duration of action compared to lidocaine and is commonly used for prolonged pain control.
Which medication is commonly used to treat malignant hyperthermia, a rare but life-threatening reaction to anesthesia?
Answer: Dantrolene
Dantrolene is the drug of choice for malignant hyperthermia, as it reduces excessive calcium release in muscle cells.
