A. observing for adequate chest rise B. assessing the facial area for cyanosis C. counting the patient's respiratory rate D. measuring the patient's oxygen saturation - ANSWER A. Observing for adequate chest rise Tidal volume- the volume of air that is moved in or out of lungs by single breath- observed by adequate chest rise. If rise is shallow, tidal volume is likely reduced. In an otherwise healthy individual, the primary stimulus to breath is a(n): A. increased level of oxygen in the blood B. decreased level of oxygen in the blood C. increased level of carbon dioxide in blood D. decreased level of carbon dioxide in blood - ANSWER C. increased level of carbon dioxide in blood Under control of the brain stem, rising levels of carbon dioxide in the arterial blood normally stimulate breathing in an otherwise healthy patient. Signs of adequate breathing in the adult include all of the following, EXCEPT: A. pink, warm, dry skin B. shallow chest rise C. symmetrical chest movement D. a respiratory rate of 16 breaths/min - ANSWER B. shallow chest rise shallow chest rise= reduced tidal volume During insertion of an oropharyngeal airway into an unconscious patient, she begins to vomit.
