b. hyperventilate the patient at 24 breaths/min.
c. adequately preoxygenate with 100% oxygen.
d. suction the oropharynx to clear any secretions.

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.
After inserting the ET tube between the vocal cords, you should remove the stylet from the tube and then:
Select one:
a. attach the bag-mask device and ventilate.
b. secure the tube with a commercial device.
c. attach an ETCO2 detector to the tube.
d. inflate the distal cuff with 5 to 10 mL of air.
d. inflate the distal cuff with 5 to 10 mL of air.
After you have intubated an apneic patient with chest trauma, your partner is auscultating breath sounds and tells you that breath sounds are faint on the right side of the chest. You should:
Select one:
a. slightly withdraw the tube as your partner auscultates breath sounds.
b. suspect that the patient has a pneumothorax on the right side of the chest.
c. immediately remove the ET tube and oxygenate the patient for 30 seconds.
d. increase the force of your ventilations as your partner reauscultates the lungs.
b. suspect that the patient has a pneomothorax on the right side of the chest.
Several attempts to orotracheally intubate an unresponsive, apneic young patient have failed. You resume bag-mask ventilations and begin transport to a hospital located 25 miles away. En route, you begin having difficulty maintaining an adequate mask-to-face seal with the bag-mask device. Assuming that you have the proper equipment, which of the following techniques to secure a patent airway would be MOST appropriate?
Select one:
a. Transillumination intubation
b. Blind nasotracheal intubation
c. An open or needle cricothyrotomy
d. Further attempts at orotracheal intubation
a. transillumination intubation
When a patient is given a paralytic without sedation:
Select one:
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.
If the ET tube has been positioned properly in the trachea:
Select one:
a. breath sounds should be somewhat louder on the right side and the epigastrium should be silent.
b. you should not see vapor mist in the ET tube during exhalation when ventilating with a bag-mask device.
c. breath sounds should be loud at the apices of the lungs but somewhat diminished at the bases.
d. the bag-mask device should be easy to compress and you should see corresponding chest expansion.
d. the bag-mask device should be easy to compress and you should see corresponding chest expansion.
Undersedation of a patient during airway management would likely result in all of the following, EXCEPT: Select one: a. respiratory depression. b. pulmonary aspiration. c. poor patient compliance. d. tachycardia and hypertension.
a. respiratory depression.
A construction worker fell approximately 15 feet and landed on his head. He is semiconscious. His respiratory rate is 14 breaths/min with adequate depth. Further assessment reveals blood draining from his nose. You should:
Select one:
a. administer oxygen via nonrebreathing mask and continue your assessment.
b. insert a nasopharyngeal airway and assist ventilations with a bag-mask device.
c. suction his nasopharynx for up to 30 seconds and apply oxygen via nasal cannula.
d. insert a nasopharyngeal airway and administer oxygen via nonrebreathing mask.
a. administer oxygen via nonrebreathing mask and continue your assessment.
You will know that you have achieved the proper laryngoscopic view of the vocal cords when you see:
Select one:
a. two white fibrous bands that lie vertically within the glottic opening.
b. the tip of the straight blade touching the posterior wall of the pharynx.
c. the thyroid cartilage bulge anteriorly as you lift up on the laryngoscope.
d. the epiglottis lift when the tip of the curved blade is resting underneath it.
a. two white fibrous bands that lie vertically within the glottic opening.
You are caring for a 69-year-old man with congestive heart failure. His breathing is profoundly labored, his oxygen saturation reads 79% on oxygen via nonrebreathing mask, and he is showing signs of physical exhaustion. Considering that your protocols do not allow you to perform rapid sequence intubation, you should:
Select one:
a. insert an oral airway, assist ventilations with a bag-mask device, and transport at once.
b. preoxygenate him with a bag-mask device and then perform blind nasotracheal intubation.
c. give him Valium for sedation, perform orotracheal intubation, and transport to the hospital at once.
d. insert a nasopharyngeal airway and ensure that the nonrebreathing mask is tightly secured to his face.
b. preoxygenate him with a bag-mask device and then perform blind nasotracheal intubation.
Approximately 10 seconds into an intubation attempt, you catch a glimpse of the patient’s vocal cords, but quickly lose sight of them. You should:
Select one:
a. sweep the patient’s tongue to the right side of the mouth and revisualize.
b. abort the intubation attempt and ventilate the patient with a bag-mask device.
c. ask your partner to apply backward, upward, rightward pressure to the thyroid.
d. gently pry back on the laryngoscope to improve your view of the upper airway.
c. ask your partner to apply backward, upward, rightward pressure to the thyroid.
To prevent muscular fasciculations associated with the use of succinylcholine, you should administer:
Select one:
a. 0.5 mg of atropine sulfate via rapid IV push.
b. 10% of the usual dose of a nondepolarizing paralytic.
c. an infusion of potassium chloride set at 5 mEq per hour.
d. 1 to 1.5 mg/kg of lidocaine over 10 to 15 minutes.
b. 10% of the usual dose of nondepolarizing paralytic.
