HCB TEST 4 fully solved graded A+
passed 2023
what is the purpose of the respiratory system? - correct answer ventilate and oxygenate the remaining
body systems and tissues
airway - correct answer passageway by which air enters and leaves the body.
alveolar ventilation - correct answer the amount of air that reaches the alveoli
artificial ventilation - correct answer forcing air or oxygen into the lungs when a patient has stopped
breathing or has inadequate breathing (positive pressure ventilation)
apnea - correct answer no breathing
cellular respiration - correct answer exchange of oxygen and carbon dioxide between cells and circulating
blood
contraction of smooth muscle that lines the bronchial passages that results in a decreased internal
diameter of the airway and increased resistance to airflow - correct answer bronchoconstriction
cyanosis - correct answer blush color of the skin due to insufficient oxygen levels in the blood
diffusion - correct answer process by which molecules move from an area of high concentration to an
area of low concentration
dyspnea - correct answer difficult or labored breathing; shortness of breath
flail chest - correct answer fracture of two or more adjacent ribs in two or more places that allows for
free movement of the fractured segment
, flowmeter - correct answer valve that indicated the flow of oxygen reaching the tissues of the body
hypoxia - correct answer deficiency of oxygen reaching the tissues of the body
intercostal - correct answer situated or extending between the ribs
nasopharyngeal airway - correct answer flexible breathing tube inserted through the patient's nostril
into the pharynx to help maintain an open airway
oropharyngeal airway - correct answer curved device inserted through the patient's mouth into the
pharynx to help maintain an open airway
paradoxical motion - correct answer movement of ribs in flail segment that is opposite to the direction of
movement of the rest of the chest cavity
pressure regulator - correct answer device connected to an oxygen cylinder to reduce pressure, so it is
safe for delivery of oxygen to a patient
pulmonary respiration - correct answer exchange of oxygen and carbon dioxide between the alveoli and
circulating blood in the pulmonary capillaries
patent airway - correct answer airway that is open and clear and will remain open and clear without
interference
respiratory arrest - correct answer when breathing stops completely
respiratory distress - correct answer increased work of breathing; a sensation of shortness of breath
(doesn't need ventilation)
respiratory failure - correct answer reduction of breathing to the point where oxygen intake is not
sufficient enough to support life (needs ventilation)
