TMC Questions and Correct Answers
Nasopharyngeal airways are indicated for pts who are
a. unconscious w/ a closed head injury
b. conscious w/ an ineffective cough
c. alert and expectorating (coughing on their own) a large amount of secretions
d. uncooperative w/ bilateral wheezing
✓ ~~~ b. conscious w/ an ineffective cough
unconscious = oralpharyngeal airway
nasopharyngeal = decreases trauma w/ suctioning
a 43wk gestational age infant has been delivered and is cyanotic and apnea. the
physician directs the RT to orally intubate the infant immediately. what is the
appropriate endotracheal tube size for this infant?
a. 2
b. 2.5
,c. 3
d. 4
✓ ~~~ c. 3
term infants are normally 3000+ g; 3000+ g = 3.0 tube; normally don't go above 3 for
babies
an 8 month old infant admitted to the pediatric unit is playing w/ marbles. the infant
suddenly develops violent coughing and is unable to cry. the RT administered a
series of back blows and chest thrusts, and the infant is now unresponsive. the
therapist should
a. continue back blow and chest thrusts
b. initiate CPR
c. perform a blind finger sweep
d. prepare to intubate
✓ ~~~ b. initiate CPR
don't continue back blows and chest thrusts bc they are unconscious (not getting
oxygen to the brain; not perfusing). only do that when they are conscious
don't perform a blind finger sweep bc it could make it worse and delay therapy
,While inserting a nasopharyngeal airway, the RT should insert the airway in the
a. opposite direction of its shape and rotate 180 degrees
b. opposite direction of its shape and rotate it 90 degrees
c. same direction of its shape without rotation
d. same direction of its shape and rotate 180 degrees
✓ ~~~ c. same direction of its shape w/o rotation
while utilizing a stylet during endotracheal intubation, the distal end of the stylet
should be
a. 1cm from the tip of the ETT
b. positioned at the level of the beveled end
c. proximal to the Murphy eye
d. positioned proximal to the cuff
✓ ~~~ a. 1cm from the tip of the ETT tube
a pt is diagnosed w/ a necrotizing pulmonary fistula in the right lung. the physician
requests that the right lung be ventilated at a pressure of 10cmH20 lower than the
left lung. the respiratory therapist should recommend providing this type of ventilation
via a
, a. transtracheal catheter device
b. double-lumen endobronchial tube
c. cricothyroidotomy
d. 14 gauge endotracheal catheter
✓ ~~~ b. double-lumen end-bronchial tube
a pt has been intubated in order to receive volume control ventilation. To inflate the
endotracheal tube cuff, the respiratory therapist should add air to the cuff
a. until no leak is heard during inspiration
b. and then remove it until a slight leak is heard at peak inspiration
c. to establish a pressure of 20mmHg
d. to establish a pressure of 40cmH20
✓ ~~~ c. to establish pressure of 20mmhg
normal cuff pressures:
18-22 mmHg and 25 - 30 mmHg
