biod 151 lab 2 Exam Questions and Answers| 100% Pass!! list, in order, the anatomical structures found in the respiratory pathway. you should begin at the nose and end at the alveoli -Answer-nose, pharynx, larynx, trachea, main bronchi, bronchioles, alveoli which of the following statements are false regarding structures within the respiratory tract a. the trachea contains cartilaginous rings to keep it from collapsing as the air flows through it b. if a patient were to aspirate, the content would likely enter the right main bronchus c. the bronchi are a part of the respiratory division of the respiratory tract d. the pharynx is part of the conducting division of the respiratory tract -Answer-c. the bronchi are a part of the respiratory division of the respiratory tract you are assessing a patient admitted to the hospital with pneumonia. they are breathing at a rate of 30 breaths per minute, what is their alveolar ventilation -Answer-AVR = 350 mL x 30 bpm = 10,500 mL/min list two reasons why we measure pulmonary ventilation -Answer-1. to assess pulmonary function 2. to assess severity of pulmonary disease 3. to monitor improvement or deterioration of a disease process which of the following statements is false regarding restrictive lung disorders a. in a restrictive lung disorder the lungs are limited with the amount of air that can be inhaled b. any disorder that produces pulmonary fibrosis is considered a restrictive lung disorder c. tuberculosis is an example of a restrictive lung disorder -Answer-all are correct which of the following statements is false regarding obstructive lung disorders a. obstructive lung disorders limit the amount of air that can be inhaled or exhaled at a given time b. individuals with an obstructive lung disorder will have an increased forced expiratory volume c. chronic bronchitis is an example of an obstructive lung disorder -Answer-b. individuals with an obstructive lung disorder will have an increased forced expiratory volume expiratory reserve volume -Answer-amount of air, in excess of tidal volume that be exhaled with maximal effort residual volume -Answer-amount of air remaining in lungs after maximal expiration vital capacity -Answer-deepest breath possible inspiratory capacity -Answer-obtained by subtracting ERV from VC functional residual capacity -Answer-amount of air remaining in lungs after normal tidal expiration total lung capacity -Answer-obtained by adding vital capacity and residual volume tidal volume -Answer-amount of air inhaled or exhaled in 1 breath during quiet breathing inspiratory reserve volume -Answer-VC - TV + ERV forced expiratory volume -Answer-obtained by having subject rapidly exhale into a spirometer minute respiratory volume -Answer-related to alveolar ventilation rate in the lab video, you were shown a spirometry read out of 3100 mL of air. based upon the information presented in lab, which pulmonary measurement was obtained -Answer- vital capacity 3100mL using the normative values provided in the lab for a healthy male, calculate the total lung capacity -Answer-TLC = VC + RV = 4700mL + 1300mL = 6000mL using the normative values provided in the lab for a healthy male, calculate the functional residual capacity -Answer-FRC = RV + ERV = 1300mL + 1200mL = 2500mL you are monitoring someone who has a respiratory rate of 14 breaths per minute. calculate their minute respiratory volume, assuming they are a healthy adult -Answer- MRV = TV x RR = 500mL x 14bpm = 7000 mL/min
