TEST BANK FOR RUPPEL’S MANUAL OF PULMONARY FUNCTION TESTING 11TH EDITION BY MOTTRAM

Chapter 2: Spirometry Test Bank MULTIPLE CHOICE 1. A subject who complains of shortness of breath has an FVC of 2.57 L, but her VC is 2.99 L. These findings suggest which of the following? a. Pulmonary fibrosis b. Chest wall abnormality c. Emphysema d. Fixed upper airway obstruction 2. A 47-year- old man with a history of cough has the following spirometry results: Measured Predicted FVC (L BTPS) 3.85 4.01 FEV1 (L BTPS) 2.14 3.33 These findings show the presence of which of the following? a. Reversible airway obstruction b. Moderate obstructive disease c. Normal lung function d. Incorrectly selected predicted values 3. A 22-year-old patient with dyspnea performs three spirometry trials. Trial 1 Trial 2 Trial 3 FVC (L BTPS) 4.21 4.49 4.65 FEV1 (L BTPS) 3.88 3.91 3.93 The pulmonary function technologist should do which of the following? a. Report the values from Trial 3. b. Report the largest sum of FVC and FEV1. c. Average the data from Trials 2 and 3. d. Perform at least one more maneuver. 4. Why should all values from a series of peak flow measurements be reported? a. PEF may decrease with repeated efforts. b. A minimum of three values must be averaged. c. Peak flowmeters do not need to be precise. d. Forced exhalation produces a bronchodilator effect. 5. Which of the following determines the shape of the “effort-independent” portion of the expiratory F-V curve? 1. Abdominal pressure during forced expiration 2. Elastic recoil of the lung 3. Flow resistance in the small airways 4. Cross-sectional area of the trachea a. 1 and 2 b. 2 and 3 c. 1, 3, and 4 d. 4 only 6. A patient being evaluated for disability has the following spirometry results: Measured Predicted FVC (L) 4.00 4.10 FEV1 (L) 2.00 3.30 MVV (L/min) 105 110 What do these findings indicate? a. The patient has moderate obstructive disease. b. The patient has restriction. c. The patient’s FEV1 is larger than measured. d. The patient did not make a good effort on the MVV
