BIOD 151 LAB 2, 3 &4 PRACTICE QUESTIONS WITH ANSWERS LATEST 2023-2024 LAB 2 list, in order, the anatomical structures found in the respiratory pathway. you should begin at the nose and end at the ... alveoli 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 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 AVR = 350 mL x 30 bpm = 10,500 mL/min list two reasons why we measure pulmonary ventilation 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 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 b. individuals with an obstructive lung disorder will have an increased forced expiratory volume expiratory reserve volume amount of air, in excess of tidal volume that be exhaled with maximal effort residual volume amount of air remaining in lungs after maximal expiration vital capacity deepest breath possible inspiratory capacity obtained by subtracting ERV from VC functional residual capacity amount of air remaining in lungs after normal tidal expiration total lung capacity obtained by adding vital capacity and residual volume tidal volume amount of air inhaled or exhaled in 1 breath during quiet breathing inspiratory reserve volume VC - TV + ERV forced expiratory volume obtained by having subject rapidly exhale into a spirometer minute respiratory volume 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 vital capacity 3100mL using the normative values provided in the lab for a healthy male, calculate the total lung capacity TLC = VC + RV = 4700mL + 1300mL = 6000mL using the normative values provided in the lab for a healthy male, calculate the functional residual capacity 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 MRV = TV x RR = 500mL x 14bpm = 7000 mL/min you are assessing a child admitted to the hospital with croup. they are breathing at a rate of 30 breaths per minute. what is their alveolar ventilation rate AVR = 350mL x 32bpm = 11,2000 mL/min 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 produced pulmonary fibrosis is considered a restrictive lung disorder c. tuberculosis is an example of a restrictive lung disorder all are true which of the following statements is true regarding obstructive lung disorders a. obstructive lung disorders limits only the amount of air that can be exhaled at a given time b. individuals with an obstructive lung disorder will have a decreased forced expiratory volume c. black lung is an example of an obstructive lung disorder b. individuals with an obstructive lung disorder will have a decreased forced expiratory volume LAB 3 Explain why someone who has hypergastrinemia (excessive secretion of gastrin) might develop gastric/stomach ulcers. Gastrin stimulates the secretions of pepsinogens and hydrochloric acid. Excess amounts would lead to erosion of the stomach lining. Explain why a patient with liver disease would have intolerance to fatty foods. The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats will not be broken down effectively. Food enters the stomach from the __________ via the _________ sphincter. Food exits the stomach via the ____________ sphincter into the___________. Your Answer: a. esophagus b. cardiac sphincter c. pyloric sphincter d. small intestine - Food enters the stomach from the ______A_____ : esophagus - via the _____B_____ sphincter. cardioesophageal sphincter (or lower esophageal sphincter/ LES) - Food exits the stomach via the ____C________ : pyloric - sphincter into the_____D______. small intestine (or duodenum) KNOW DIAGRAM of digestive system know diagram A patient is experiencing vitamin toxicity. What type of vitamin would be causing this toxicity? Explain your answer. A. Water soluble vitamin B. Fat soluble vitamin C. All of the above B. Fat soluble vitamin. Fat soluble vitamins are stored within the body's fat stores making it harder for the body to rid itself of them. A doctor is looking to prescribe a larger dose of a vitamin that would not easily cause vitamin toxicity. What type of vitamin would be the best to prescribe? [Show More]
