UNIT 4 EDAPT: OBSTRUCTIVE AND RESTRICTIVE LUNG DISEASES EXAM QUESTIONS AND ANSWERS 100% CORRECT!!

The FEV1/FVC ratio - ANSWER a measure of the percentage of a patient's vital capacity that can be expired in the first second of expiration restrictive LUNG disease - ANSWER The NP reviews the results of a patient's pulmonary function tests and notes that the FEV1, FVC, and total lung capacity (TLC) are reduced. The FEV1/FVC ratio is normal. Based on interpretation, this reflects: RESTRICTVE LUNG DISEASE - ANSWER the FEV1, FVC and TLC are all reduced this indicates: obstructive problem. - ANSWER A normal FEV1/FVC ratio is a clue that this is not a(n) 80 - ANSWER The normal range for the FEV1/FVC is _____%. 80%; second - ANSWER a pt w norm lungs should be able to exhale _____ of forced vital capacity within the first ____ Decreased forced expiratory flow (FEV1). - ANSWER What pulmonary function test (PFT) findings are anticipated based on the diagnosis of chronic bronchitis? obstructive - ANSWER what kind of disease is chronic bronchitis? decreased - ANSWER obstructive diseases lead to ___ expiratory flow rates and FEV1 air trapping - ANSWER common in obstructive disease which will cause an increased TLC. decreased diffusing capacity - ANSWER typically only occurs in emphysema, not chronic bronchitis. residual volume-Since that volume cannot be exhaled, it cannot be measure. - ANSWER what can simple spirometry NOT measure Pulmonary function tests (PFTs) - ANSWER non-invasive tests that provide information about lung function; alone cannot differentiate among the causes of respiratory abnormalities. Therefore, the patient's history, physical exam and other diagnostics must be considered when making a diagnosis; can help the NP determine the patient's respiratory pattern, specifically if the abnormality is due to an obstructive or restrictive problem. Once the pattern is identified, these allow the NP to determine the severity of the disease. This data com
