A 45 year-old client is recovering in the intensive care unit after undergoing a surgical
procedure to repair a hernia. The client remains unconscious. To prevent soft tissue
obstruction, the respiratory therapist should recommend a(n)
,• double-lumen endobronchial tube
• oropharyngeal airway
• bite block
• nasopharyngeal airway ✔✔b. oropharyngeal airway
Quality control material has published values for pH of 7.20, PO2 of 65 mmHg. Documentation
indicates the range of pH is 0.5% and is 3% for PO2. Machine results are as follows:
Run 1: pH 7.19, PO2 64
Run 2: pH 7.10, PO2 69
Run 3: pH 7.21, PO2 65
Which quality control run(s) indicate the machine is out of control?
• Run 1 and 2
• Run 2 and 3
• Run 3 only
• Run 2 only ✔✔d. Run 2 only
A respiratory therapist is considering a client's readiness to wean from mechanical ventilation.
To determine the A-aDO2, the therapist will need which of the following?
• ABG and alveolar oxygen tension
,• VD/VT and PAO2
• CaO2 and PAO2
• VD/VT and ABG ✔✔a. ABG and alveolar oxygen tension
A client with increased airway resistance from a fixed upper airway obstruction would benefit
most from which of the following?
• bronchodilator therapy
• epinephrine
• heliox therapy
• aerosolized atropine ✔✔c. heliox therapy
Evaluating MIP (maximum inspiratory pressure) is most useful in evaluating which of the
following?
• presence of a restrictive pulmonary defect
• effectiveness of cough
• presence of obstructive pulmonary defect
• inspiratory muscle strength ✔✔d. inspiratory muscle strength
, An air-entrainment jet nebulizer is set at 50%. The respiratory therapist analyzes the oxygen
coming from the end of the tubing and finds it is 60%. Which of the following most likely
explains this finding?
• poorly calibrate analyzer
• excess water in the tubing
• low flow through the jet orifice
• leak in the tubing ✔✔b. excess water in the tubing
During a preoperational test of the ventilator with a test lung, the respiratory therapist notes a
return tidal volume of 600 cc. Ventilator settings are:
Mode:
Assist/control
FiO2: 0.50
Mandatory rate: 10
VT: 750 mL
What action should the therapist take?
• examine the ventilator circuit for proper connections
• obtain a larger test lung
• increase the set tidal volume to 900 mL
