AIRWAY 6 Flashcards
Before intubating a patient who has been chemically sedated and paralyzed, it is MOST important for the paramedic to:
A: administer 0.5 mg of atropine sulfate.
B: hyperventilate the patient at 24 breaths/min.
C: adequately preoxygenate with 100% oxygen.
D: suction the oropharynx to clear any secretions.
C: adequately preoxygenate with 100% oxygen
Diazepam and midazolam provide all of the following therapeutic effects, EXCEPT:
A: sedation.
B: analgesia.
C: anxiolysis.
D: retrograde amnesia.
B: analgesia.
Drugs such as vecuronium bromide (Norcuron) and pancuronium bromide (Pavulon) are MOST appropriate to administer when:
A: extended periods of paralysis are needed.
B: longer-acting paralytics are contraindicated.
C: you have a transport time of less than 15 minutes.
D: intubation of the patient is anticipated to be difficult.
A: extended periods of paralysis are needed.
Fentanyl (Sublimaze) is a:
A: narcotic analgesic.
B: benzodiazepine sedative.
C: sedative-hypnotic drug.
D: butrophenone sedative.
A: narcotic analgesic.
If the patient’s oxygen saturation drops at any point during rapid sequence intubation, you should:
A: stop and hyperventilate the patient at a rate of 24 breaths/min.
B: abort the intubation attempt and ventilate with a bag-mask device.
C: apply posterior cricoid pressure and continue the intubation attempt.
D: continue the intubation attempt and monitor the cardiac rhythm closely.
B: abort the intubation attempt and ventilate with a bag-mask device.
If used properly, and under the correct circumstances, sedation during airway management:
A: chemically paralyzes the patient, thus facilitating placement of an advanced airway device.
B: effectively increases patient compliance, thus making definitive airway management safer to perform.
C: significantly reduces the pain and discomfort associated with laryngoscopy and ET intubation.
D: minimizes the risks of bradycardia and hypotension that occasionally occur during advanced airway management.
B: effectively increases patient compliance, thus making definitive airway management safer to perform.
Neuromuscular blocking agents:
A: are most commonly used as the sole agent to facilitate placement of an ET tube.
B: convert a breathing patient with a marginal airway into an apneic patient with no airway.
C: induce total body paralysis within 10 to 15 minutes following administration via IV push.
D: have a negative effect on both cardiac and smooth muscle and commonly cause dysrhythmias.
B: convert a breathing patient with a marginal airway into an apneic patient with no airway.
Nondepolarizing neuromuscular blocking agents include all of the following, EXCEPT:
A: vecuronium bromide.
B: rocuronium bromide.
C: pancuronium bromide.
D: succinylcholine chloride.
D: succinylcholine chloride.
Paralytic medications exert their effect by:
A: blocking the release of epinephrine and norepinephrine from the sympathetic nervous system.
B: competitively binding to the motor neurons in the brain, thus blocking their ability to send messages.
C: functioning at the neuromuscular junction and relaxing the muscle by impeding the action of acetylcholine.
D: blocking the function of the autonomic nervous system and impeding the action of acetylcholinesterase.
C: functioning at the neuromuscular junction and relaxing the muscle by impeding the action of acetylcholine.
Reemergence phenomenon is characterized by:
A: pleasant dreams or vivid nightmares.
B: incomplete recollection of previous events.
C: a transient, but significant, drop in heart rate.
D: a drop in blood pressure as medication wears off.
A: pleasant dreams or vivid nightmares.
Undersedation of a patient during airway management would likely result in all of the following, EXCEPT:
A: respiratory depression.
B: pulmonary aspiration.
C: poor patient compliance.
D: tachycardia and hypertension.
A: respiratory depression.
When a patient is given a paralytic without sedation:
A: he or she is fully aware and can hear and feel.
B: you should only give one-tenth of the standard dose.
C: placement of an ET tube is less traumatic.
D: paralysis is not achieved and intubation is not possible.
A: he or she is fully aware and can hear and feel.
Which of the following dosing regimens for ketamine would MOST likely be used to induce sedation prior to administering a neuromuscular blocker?
A: 2 mg/kg
B: 25 to 50 mg
C: 0.2 to 0.3 mg/kg
D: 0.5 to 1 mg/kg
A: 2 mg/kg
Which of the following is NOT characteristic of a depolarizing neuromuscular blocking agent?
A: Bradycardia
B: Tachycardia
C: Muscle fasciculations
D: Short duration of action
B: Tachycardia
Which of the following medications is a dissociative anesthetic that produces anesthesia through hallucinogenic, amnesic, analgesic, and sedative effects?
A: Versed
B: Ketamine
C: Fentanyl
D: Diazepam
B: Ketamine
