A pressure-volume loop ventilator graphic shows no rise in pressure for the first 200 mL of delivered volume. The therapist should
- increase inspiratory flow rate
- increase PEEP
- decrease tidal volume
- decrease inspiratory flow rate - Correct Answer - B.
In this question the description of the pressure volume loop would indicate a flat bottom as manifested by no rise in pressure with the first 200 mL of delivered volume. We call this a "flat football". The solution is to increase PEEP to a level that the pressure begins to rise immediately as volume is introduced.
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
- sustained maximal inhalation (incentive spirometer)
- deep breathing coaching 1 / 4

- intubation and mechanical ventilation - Correct Answer - 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.
After performing minimum occluding volume technique with a 65-kg (143-lb) patient who is orally intubated with a 7.0-mm ET tube, the respiratory therapist should NEXT
- check ET tube cuff pressure
- perform tracheal palpation
- order a chest radiograph
- document ET tube markings at the lips - Correct Answer - A.
The ET tube cuff pressure may be adjusted correctly by several techniques including minimum leak technique (also called minimum occluding volume, minimal seal technique, and the use of a pressure manometer called a cuffalator. If minimum seal or minimal leak technique is used, the respiratory therapist is still required to monitor the pressure after the technique is performed. Although this is often not done in real life, it is technically part of the procedure.
The respiratory therapist observes an ECG wave form on a patient that is consistent with atrial tachycardia. The patient is complaining of chest pain, dizziness, and nausea. The respiratory therapist should recommend
- unsynchronized defibrillation
- Atropine sulfate 2 / 4
- | P a g e
pg. 3
- epinephrine
- cardioversion - Correct Answer - D.
Non-deadly arrhythmias, such as this one, may be addressed through cardioversion. Cardioversion is a form of defibrillation with low wattage and with the synchronization set to "active". This allows the shock to be synchronized to the R wave.
A 38-year-old male presents in the emergency department (ED) complaining of frequent vomiting. The following laboratory data is
available: Arterial blood gases
pH 7.55 PaCO2 42 torrPaO2 85 torrHCO3- 31 mEq/LBE +7 mEq/LFIO2 0.21K+ 3.0 mEq/LCl- 95 mEq/LNa+ 135 mEq/L Which of the following should the respiratory therapist recommend?
- administer NaCL
- administer NaHCO3-
- administer KCL
- administer volume-expanding fluids - Correct Answer - C.
This patient has a CO2 of 42 mmHg, which suggests adequate ventilation. However, the high pH is associated with alkalosis. Because the CO2 is normal, the cause of the alkalosis must be metabolic in nature. One treatment for metabolic alkalosis is to administer potassium chloride or KCl.
A patient is receiving volume-controlled ventilation following bariatric surgery for obesity. Which of the following medications should the respiratory therapist recommend to ensure the patient's comfort and assist in ventilator management? 3 / 4
- | P a g e
pg. 4
- Pronestyl
- morphine sulfate
- vecuronium bromide (Norcuron)
- Mestinon - Correct Answer - B.
Morphine sulfate is one of the best medications to administer to patients receiving mechanical ventilatory support to help the patient rest pain- free and to generally sedate and relax the patient.
A patient has idiopathic pneumonia with consolidation in the right lower lobe. The physician suspects a bacterial infection. Which of the following will provide conclusive data to rule out the physician's suspicions?
A. WBC
- color of sputum
- sputum acid-fast stain
- oral temperature - Correct Answer - A.
A bacterial infection is diagnosed primarily by examining the white blood cell count, also called the leukocyte count. An elevated temperature and yellow sputum indicate the possibility of an infection but are not confirming in nature.
After making the universal sign of choking, a person collapses. The observer should FIRST
- check for a pulse
- call for help
- perform abdominal thrusts
