How many minutes will a full E cylinder oxygen tank last when running at 5 L/min?
A. 616 minutes
B. 123 minutes
C. 1320 minutes
D. 90 minutes

B.
The E cylinder tank factor is 0.28. A full E cylinder is 2200 PSI. 2200x0.28 is
equal to 616 L. 616 divided by 5 (the liter flow to the patient) is equal to
approximately 123 min. That is how long the tank will last in minutes. To get
hours, you must further divide by 60 minutes.
Which of the following would be the most effective, appropriate method for resolving
atelectasis in a spontaneously breathing, post operative patient who is under the
influence of sedation and will not respond to verbal stimuli?
A. IPPB
,B. sustained maximal inhalation (incentive spirometer)
C. deep breathing coaching
D. intubation and mechanical ventilation
Give this one a try later!
A.
A postoperative patient under sedation, and possibly in pain, may be
tempted to breathe less, causing respiratory acidosis and atelectasis. To
correct this problem, IPPB therapy is most appropriate. Incentive
spirometry would also help but the patient is unable to respond to verbal
stimuli. This alone is an indication for IPPB therapy.
Which of the following conditions would benefit most from a thoracentesis?
A. atelectasis
B. complete opacification of the right lung
C. small pneumothorax
D. pericardial contusion
Give this one a try later!
C.
A thoracentesis is a procedure that removes air or fluid from the pleural
space. This would be appropriate with a small pneumothorax. A large
pneumothorax, however, would require chest tubes.
The respiratory therapist responds to an adult patient on a ventilator whose low
pressure alarm is sounding. The therapist determines the 6.0 mm ET tube is in proper
position according to the markings. Gas escaping around the ET tube is audible. The
therapist should
A. switch to a larger ET tube
B. switch to a cuffless ET tube
,C. schedule the patient for a tracheotomy
D. add air to the cuff
Give this one a try later!
A.
The first, most obvious problem in this question is that an adult patient has a
6.0 mm ET tube. For a normal sized adult, this endotracheal tube size is
likely too small. Further evidence indicates gas escaping around ET tube.
This is also likely due to a small endotracheal tube.
A patient is receiving oxygen by non-rebreathing mask at a flow of 10 L/min.
Spontaneous tidal volume is 500 mL and spontaneous respiratory rate is 20 /min. What
change should the therapist recommend?
A. Increase flow until reservoir bag collapses completely with each breath
B. Increase flow to 14 L/min
C. Ensure an adequate mask seal on the patient's face
D. Order arterial blood gas analysis
Give this one a try later!
B
A patient who is breathing a tidal volume of 600 mL at a rate of 20/min has
a minute ventilation of 12 L. If the non-rebreathing mask is set at only 10
L/min, the total flow to the patient is insufficient. The flowrate should meet
or exceed the inspiratory demand of the patient. Therefore, increasing to 14
L/min is most appropriate.`
Which of the following airway clearance therapies should be administered first in the
order of therapy?
A. verbal coaching for coughing
B. oropharyngeal suctioning
C. nasal tracheal suctioning
D. postural drainage and percussion
, Give this one a try later!
D.
Of the options offered. the first step in mobilizing secretions would be to
perform postural drainage and percussion, followed by verbal coaching of
coughing and then suctioning. Suctioning and coughing requires that the
sputum be close to the upper airway for expectoration. Prior to that,
sputum must be moved from the lower airways to the upper airways
through methods that mobilize secretions. Postural drainage and
percussion is one of those methods. Other methods include vibration
therapy, PEP therapy, and chest wall oscillation therapy (Vest).
A respiratory therapist is responsible for an instructional program to healthcare
workers in a pediatric hospital regarding the avoidance of nosocomial infection
among patients. Which of the following should be included in the program?
1. universal precautions2. hand washing techniques3. managing sterile fields4. proper
equipment cleaning
A. 2 and 3 only
B. 1 and 3 only
C. 2 and 4 only
D. hand washing techniques
Give this one a try later!
D.
Nosocomial infections are those infections that are spread among hospital
patients. To prevent them, universal precautions, proper handwashing, use
of sterile fields, and proper equipment cleaning all will play a part in
infection prevention
A spontaneously breathing patient has the following arterial blood gas results:
pH 7.38 PaCO2 42 mmHgPaO2 76 mmHgHCO3- 24 mEq/LBE 0 mEq/L
Which of the following supplemental oxygen levels is most appropriate?
A. 2 L/min nasal cannula
A. 616 minutes
