Induction & Pharmacology
This induction agent is most associated with adrenal suppression
What is etomidate
This is a common cause of difficult mask ventilation
What is presence of a beard, obesity (BMI > 26), edentulous, elderly (> 55), snoring
The term SVR stands for
What is systemic vascular resistance
This happens to oxygen consumption during shivering
What is an increase
This is the treatment for local anesthetic systemic toxicity
What is intralipids
Propofol induces anesthesia by acting as an agonist at this primary receptor
What is GABA-A
These three airway axes must be aligned to optimize the view for tracheal intubation
What are the oral, pharyngeal, and laryngeal axes
This is the most common cause of tachycardia during surgery
What is inadequate/light anesthesia or pain
This happens to MAC as age increases
What is a decrease
This is the antidote for heparin overdose
What is protamine
This drug is most likely to increase heart rate and blood pressure during induction
What is ketamine
This nerve provides the sensory input that triggers a laryngospasm
What is the superior laryngeal nerve
This is the first-line vasopressor for spinal-induced hypotension in obstetric patients
What is phenylephrine
This is the most sensitive indicator of ventilation
What is PaCO₂
This is what happens to ETCO₂ during a pulmonary embolism
What is a decrease
This neuromuscular blocker is associated with histamine release
What is atracurium, mivacurium or succinylcholine
This is the primary action of the posterior cricoarytenoid muscles
What is abduct the vocal cords
At low doses, dopamine primarily stimulates these receptors
What are dopaminergic receptors
This condition is not reliably detected by pulse oximetry and can be treated with hyperbaric oxygen therapy
What is carbon monoxide poisoning
This is the earliest sign of local anesthetic systemic toxicity
What are CNS symptoms (tinnitus/metallic taste/circumoral numbness)
This electrolyte abnormality is associated with succinylcholine administration
What is hyperkalemia
This nerve innervates the posterior 1/3 of the tongue
What is the glossopharyngeal nerve (CN IX)
This receptor is primarily stimulated by norepinephrine to increase blood pressure
What is the alpha-1 receptor
This physiologic change shifts the oxyhemoglobin dissociation curve to the right (name one)
What is: increased CO₂ (hypercarbia), increased temperature, acidosis(inc H ions), inc 2,3 DPG
This is the classic triad of an air embolism
What are hypotension, hypoxia, and decreased ETCO₂ (hypocarbia/hypocapnia)
