| Question | Answer |
|---|---|
| Which of the following are potential indications for positive airway pressure therapies? | D) I, II, III, and IV I. Reduce air-trapping in asthma or chronic obstructive pulmonary disease. II. Help mobilize retained secretions. III. Prevent or reverse atelectasis . IV. Optimize bronchodilator delivery. |
| Contraindications for positive airway pressure therapies include all of the following except: | D) air-trapping/pulmonary overdistention in chronic obstructive pulmonary disease. |
| All of the following are hazards of positive airway pressure therapies (EPAP, PEP, CPAP) except: | B) improvement in ABG values |
| Hazards of positive airway pressure therapies associated with the apparatus used include which of the following? | C) I, II, III, IV, and V I. Increased work of breathing II. Claustrophobia III. Increased ICP IV. Vomiting and aspiration V. Skin breakdown and discomfort |
| A physician orders positive expiratory pressure therapy for a 14-year-old child with cystic fibrosis. Which of the following should be monitored? | B) I, II, III, and IV only I. Sputum production II. Breath sounds III. Pulse rate IV. Breathing pattern |
| Which of the following best describes positive expiratory pressure (PEP) therapy? | A) Expiration against a variable flow resistance. |
| In theory, how does positive expiratory pressure (PEP) help to move secretions into the larger airways? | B) I and II I. Filling underaerated segments through collateral ventilation. II. Preventing airway collapse during expiration. |
| Proper instructions for positive expiratory pressure include all of the following except. | B) Exhale forcefully and maintain an expiratory pressure of 10 to 20 cm H2O. |
| A physician orders bronchodilator drug therapy in combination with positive expiratory pressure (PEP). Which of the following methods could you use to provide this combined therapy? | A) II and III II. Attach a metered-dose inhaler to the system’s one-way valve inlet. III. Place a small-volume nebulizer in-line with the PEP apparatus. |
| What is the movement of small volumes of air back and forth in the respiratory tract at high frequencies (12 to 25 Hz) called? | C) Oscillation |
| Which of the following parts are required to conduct high-frequency external chest wall compression? | C) I and III I. Variable air-pulse generator III. Nonstretch inflatable thoracic vest |
| All of the following are typical of high-frequency external chest wall compression therapy except: | D) long inspiratory oscillations. |
| Which of the following determines effectiveness of high-frequency external chest wall compression therapy? | C) I and III I. Compression frequency III. Flow bias |
| The airway clearance technique that uses a pneumatic device to deliver compressed gas minibursts to the airway at rates above 100/min best describes which of the following? | A) Intrapulmonary percussive ventilation |
| Which of the following is true about exercise and airway clearance? | C) I, II, III, and IV I. Exercise can enhance mucus clearance. II. Exercise can improve pulmonary function. III. Exercise can improve V/Q matching. IV. Exercise can cause desaturation in some patients. |
| Patients can control a flutter valve’s pressure by changing what? | C) Their expiratory flow |
| Advantages of the flutter valve over other bronchial hygiene methods include all of the following except: | B) greater effectiveness. |
| Which of the following is not an advantage of the Acapella over the flutter? | C) It is more portable. |
| Which of the following should be considered when selecting a bronchial hygiene strategy? | D) I, II, III, and IV I. Patient’s goals, motivation, and preferences. II. Effectiveness and limitations of technique or method. III. Patient’s age, ability to learn, and tendency to fatigue. IV. Need for assistants, equipment, and cost. |
| Which of the following airway clearance techniques would you recommend for a 15-month-old infant with cystic fibrosis? | A) Postural drainage, percussion, and vibration |
| Which of the following airway clearance techniques would you recommend for a patient with a neurologic abnormality (bulbar palsy) and intact upper airway? | D) I and III I. Postural drainage, percussion, and vibration III. Mechanical insufflation-exsufflation |
| In assessing an adult outpatient for bronchial hygiene therapy, has (1) no history of cystic fibrosis or bronchiectasis, (2) sputum production of 30 to 50 ml/day, (3) an effective cough, and (4) good hydration. Which of the following would you recommend? | B) positive expiratory pressure therapy |
