Evalutation of maximum expiratory pressure is most useful in which of the following? a. fixed upper airway obstruction b. presence of restricive defect c. inspiratory muscle strngth d. forcefulness of cough - ANSWER d. forcefulness of cough Explanation: MEP is used to measure the forcefulness of a patients cough and used to determine if the patient is able to sustain ventilation. A bronchoscopy is used to diagnose a. atelectasis b. idiopathic chronic bronchitis c. malignant processes d. emphysema - ANSWER c. malignant processes Explanation: Bronchoscopy is used to diagnose foreign body obstruction, active bleeding causes, pathogenic involvement (to identify organisms) and cancerous or malignant processes or areas. What does Metabolic acidosis result in? - ANSWER Significantly low pH, hyperglycemia, marked hyperpnea, and potentially normal oxygen levens. The respiratory therapist measures the functional residual capacity with a body box and determines the related value is 4.3 L. The FRC value is 3.4 L when determining via helium dilution method. Which of the following can explain the difference? A. inconsistent patient effort B. significant amount of non-ventilated alveoli C. depleted helium analyzer D. hyperventilation secondary to panic in the body box - ANSWER B. significant amount of non-ventilated alveoli Explanation : A patient with COPD has significant non-ventilated lung space. The measurement of total lung capacity, FRC, and RV done by helium dilution and nitrogen washout will likely be less accurate and show a smaller FRC compared to pulmonary function testing done by a body box. A body box can indirectly measure non-ventilated alveolar space. Using the formula for calculation of cardiac index, how would a morbidly obese patient's C.I. compare to that of a person at ideal body weight? A. cardiac index would remained unchanged B. cardiac index would be higher C. cardiac index would be unpredictable
