A 45 y/o pt is recovering in the ICU after a surgical repair to a hernia. The pt is
unconscious. To prevent soft tissue obstruction, the RT would recommend to do what...
- ANSWER-Use an oropharyngeal airway.
An OPA is the primary mechanism used to prevent the tongue from falling back and
obstructing the airway.
In which of the following situations should an HME be replaced w/ heated humidity? -
ANSWER-Presence of thick secretions.
An HME should be changed if the pt has thick secretions or is hypothermic. If the pt is
hypothermic they can't breathe out enough heat into the exchanger to capture and
rebreathe.
A 5 y/o pt with acute epiglottis has been given a trach and is returned to the ED for
monitoring. The pt is now breathing through a trach tube. Which of the following is most
important at this time? - ANSWER-Provide heated humidity.
A pt who has a trach tube in place is unable to naturally humidify inspired gases b/c the
natural humidification processes of the body, including the nasal passages and
oropharynx, are bypassed. In this case, providing heated humidity, which can make up
the entire humidity deficit, is paramount.
The preferred method of delivery for humidification for a pediatric pt during a 12 hour
transport is what... - ANSWER-HME.
An HME is most practical for a short duration transport.
The sudden sounding of a high pressure vent alarm is noted on a pt receiving VC
mechanical ventilation. The RT notes the ET tube is 27cm at the teeth and breath
sounds are absent when auscultating the left hemithorax. The RT should immediately
do what... - ANSWER-Withdraw the ET tube until breath sounds are bilateral.
The proper placement of an oral ETT is when the teeth/lip line matches w/ markings on
the tube somewhere in the low 20's. This ETT is 27cm at the teeth, indicating the tube is
advanced too far. In this case, it is likely the tube has advanced into the right main stem
bronchus, which would cause a high pressure alarm to sound.
A pt intubated w/ a 7.0 ETT requires suctioning. Which of the following suction catheters
would be most effective? - ANSWER-10 Fr catheter.
