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. Pulmonar ... y fibrosis b. Chest wall abnormality c. Emphysema d. Fixed upper airway obstruction ANS: C FVC is often lower than VC in patients with obstructive diseases if forced expiration causes airway collapse. This pattern is often seen in emphysema because of loss of tethering support of the airways. DIF: 2 REF: p. 48 OBJ: EL-1 MSC: NBRC: CPFT 3B-3 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 ANS: B While the ratio of FEV1/VC defines obstruction, the severity of obstruction is defined by the degree to which the FEV1 is reduced. Moderate FEV1= 60% to 69% of predicted; 2.14  3.33 = 64%. DIF: 2 REF: p. 51 OBJ: EL-2 MSC: NBRC: CPFT 3C-3 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. ANS: D [Show More]
