MIdterm for RCP 180 QUESTIONS WITH COMPLETE SOLUTIONS

What is a normal FEV1 in a normal healthy adult? This is an exact statistical percentage value. correct answer: - 83% What shape of the flow-volume loop is typical for the patient with a fixed upper airway obstruction? correct answer: -Box shaped Which volumes or capacities cannot be measured by simple Spirometry? correct answer: (FRC, TLC, RV) Exam FRC and RV When an SVC is significantly larger than a FVC, what does this indicate? correct answer: An Obstruction is present What is the primary indication for assessing lung volumes? correct answer: - Daryl said evaluate respiratory function, quantify severity of pulmonary disease, assess response to treatment, disability evaluation, pre-op risk assessment - Teacher Diagnosis and severity of restrictive disease 1. What conditions is DLCO measurement indicated to evaluate? correct answer: Restrictive disease such as sarcoidosis systemic disease, pulmonary fibrosis. Emphysema Which disease processes have potential to cause a restrictive pattern? correct answer: Sarcoidosis, pulmonary fibrosis, ILD, neuromuscular 1. According to the ATS-ERS general considerations guidelines, what are the variables within the laboratory environment, which must be noted and recorded? correct answer: Ambient temperature, barometric, time and date 1. What are possible negative effects of multiple PEF AND/OR FEV1 MANEUVERS? Why should the values be noted? correct answer: Decrease in patient effort, and bronchospasms. 1. Be able to solve for predicted value. correct answer: Actual value/Predicted value =% predicted 1. Know normal values for FEV1, FVC, FEV1/FVC%, and be able to interpret results. correct answer: FEV1 = 80 - 120 of FVC FVC = 80% less than = restrictive, FEV1/FVC = 70% 1. In Spirometry, what makes values repeatable therefore reportable? correct answer: 3 minimum tests within 150 ml, take largest of two maneuvers and it doesn't have to be same maneuver
