GI, lung sounds, fever, skins, vitals, O2 ext. 3. The amount of air moved in and out of the lungs during a normal, quiet respiration is called: a. Tidal volume. 4. Diffusion is defined as: a. Movement of molecules across a membrane from an area of greater concentration to an area of lower concentration. b. Question: An example of diffusion in the respiratory system is: i. Movement of O2 from the alveoli into the pulmonary capillaries across the alveolar membrane. 5. Which of the following is the purpose of lung surfactant? a. Decrease the surface tension of water in the alveoli. b. Question: All of the following are characteristics of the second phase reaction of an asthma attack EXCEPT: i. Loss of surfactant in the alveoli. 6. The functional unit of the respiratory tree is the: a. Alveolus. 7. Your patient is a 16-year-old male who attempted suicide. He is unconscious and apnei, lying supine on a garage floor. The family states they found the patient unconscious in the front seat of a car that was running in an enclosed garage. HR=70, BP=100/60, RR=0. In addition to an IV of normal saline, which of the following is the most appropriate? a. Remove the patient from the garage, initiate BVM ventilations with 100% O2, intubate, and transport to a hospital with a hyperbaric chamber. 8. A 67 year old male is unconscious, sitting in a chair, and has agonal respirations. His wife states that he was up all night with difficulty breathing and chest discomfort but would not go to the hospital.

Afterload=The resistance against which the heart must pump. a. an increase in the peripheral vascular resistance will decrease stroke volume and conversely a decrease in peripheral vascular resistance will allow stroke volume to increase. 13.
