Ensure that the manual resuscitator is connected to an oxygen source. Correct Answer: A RT is
manually Ventilating a pt during a cardiopulmonary resuscitation attempt. An ABG is drawn and
the results are as follows
pH: 7.27
PaCO2: 38 mmHg
HCO3: 17 mEQ/L
PaO2: 44 mmHG
Based on this info, the RT should do which of the following?
- Ensure that the manual resuscitator is connected to an o2 source
- perform endotracheal intubation
- use both hands to compress the bag
- increase the ventilatory rate
begin manual ventilation Correct Answer: A 16 year old female has just been admitted to the
ED following a bicycling accident. She is receiving supplemental O2 via non-rebreathing mask.
While standing at the bedside, the RT notes the onset of ataxic breaething. Which of the
following should the therapist do?
- begin manual ventilation
- intubate and initiate mechanical ventilation
- continue to monitor and observe
- perform arterial blood gas analysis
lowers the diaphragm and reduces the possibility of its puncture Correct Answer: While
preparing a patient for a thoracentesis, the pt asks the RT why he must be sitting upright. TheRT
would explain to the patient that sitting upright:
- reduces the likelihood that the pt will experience discomfort
- makes it easier for the physician to aspirate fluid from the pleural space
- makes it more comfortable for the patient to breathe during the procedure
- lower the diaphragm adn reduces the possibility of its puncture
Increase the frequency of suctioning through the catheter Correct Answer: A patient with
chronic hypercapnia is receiving home oxygen therapy by transtracheal cather at 1 LPM. He
calls the respiratory clinic and informs the RT that he has had increasing episodes of rice sized
mucus balls lodging in the catheter. Which of the following would NOT be appropriate advice
for the therapist to give the patient?
- increase the frequency of suctioning through the catheter
-call his physician to prescribe a mucoevacuent
- increase his intake of systemic fluids
- increase the frequency of cleaning the catheter
insert a smaller restrictive orifice in the device Correct Answer: A RT is asked to assess a COPD
patient who is in a pulmonary rehabilitation program. During the interview, the patient tells the
, therapist that he has been working with a resistive training device for two weeks and taht he is
able to tolerate the device for 15 minutes. What should the therapist do?
- instruct the patient to exhale forecfully through the device
- instruct the patient to continue present therapy
- insert a smaller restrictive orifice in the device
- insert a larger restrictive orifice in the device
transtracheal oxygen catheter Correct Answer: A home care patient receiving continuous oxygen
therapy via nasal cannula has become increasingly noncompliant in her oxygen therapy and
states she is concerned about appearance. Which of the following would be most appropriate for
the RT to suggest?
- discontinue oxygen therapy
- nasal catheter
- transtracheal oxygen catheter
- oxygen conserving cannula
apply firm pressure to the puncture site for at least 5-10 minutes Correct Answer: Immediately
after assisting with a transtracheal aspiration, the respiratory therapist should:
- apply firm pressure to the puncture site for atleast 5-10 mins
- administer an anesthetic to the neck area
- instruct the patient to take slow deep breaths and cough
- nebulize 3cc of 1% methylene solution
proceed with chest tube placement Correct Answer: A RT is assisting the physician with needle
aspiration to relieve a tension pneumothorax. The procedure has been successful. Which of the
following should be done next?
- obtain and ABG
- obtain a Chest Xray
- proceed with the chest tube placement
- ensure airway patency
begin open cardiac massage Correct Answer: A 42 year-old man who sustained a knife stab
wound to the left chest has been brough to the ED. On arrival the patient is pulseless with a wide
complex rhythm at a rate of 20 bpm. He is immediately orotracheally intubated and an
anterolateral left thoracotomy is done. The pericadial sac was found to be dilated and filled with
blood. Pericadiocentesis is then performed for pericadium decompression. The next step in the tx
of the pt should be to:
- begine closed chest cardiac massage
- begin open cardiac massage
- administer lidocaine
- establish and intra-arterial access line
re-expansion pulmonary edema Correct Answer: Following the removal of 1650 mL of pleural
fluid, a pt suddenly becomes diaphoretic and complains of chest pain and dyspnea. Vital signs
reveal a RR of 28/min, a HR of 124 bpm, and BP of 138/86 mmHg. Which of the following is
the possible cause of this patients condition?
