NIU NURSING 308 EXAM 2 EXAM QUESTIONS AND ANSWERS
Describe the role of cilia in the mucosal membranes as part of the respiratory system. - CORRECT
ANSWERS✓✓Warms and humidifies inspired air and removes foreign particles from it.
What is the primary function of the pulmonary system? - CORRECT ANSWERS✓✓Diffuse gasses into and
out of the blood.
Ventilate the alveoli.
perfuse the lungs so the body recieves oxygen.
Where in the brain, are respirations controlled? - CORRECT ANSWERS✓✓Medulla oblongata
What is volunary breathing necessary for? - CORRECT ANSWERS✓✓talking, singing, laughing, and
holding ones breath.
What is the goal of nursing care for a patient who has ARDS - CORRECT ANSWERS✓✓Indirect & direct
care
Early detection and support
placing patient in prone position
maintaining adequate oxygenation
mechanical ventilation involving PEEP and an inverse I: E ration
direct lung care: - CORRECT ANSWERS✓✓apiration, near drowning, viral bacterial pnemonia, pulmonary
contusion, transthoracic radiation, oxygen toxicity, & inhalation injury.
Indirect lung care: - CORRECT ANSWERS✓✓sepsis, shock, head injury, non thoracic trauma, pacreatis,
burns, cardio pulmonary bypass, embolism, DIC
which nerve provide the lungs with parasympathetic innervation? - CORRECT ANSWERS✓✓Vagus nerve
or vagal nerve stimulation
, Ventilation - CORRECT ANSWERS✓✓mechanical movement of gas or air in and out of the lungs
Perfusion - CORRECT ANSWERS✓✓the movement of blood into and out of the capillary beds of the lungs
to the body organs and tissues
Diffusion - CORRECT ANSWERS✓✓the movement of gases between the air spaces in the lungs and in the
bloodstream
irritant receptors - CORRECT ANSWERS✓✓Found in the epithelium of conducting airways; sensitive to
noxious aerosols, gases, particular matter and initiate the cough reflex
stretch receptors - CORRECT ANSWERS✓✓Located in the smooth muscles of airways, decrease the
ventilatory rate and volume when stimulated, occurs in newborns and adults
J receptors - CORRECT ANSWERS✓✓Located near the capillaries in the alveolar septa; sensitive to
increased pulmonary capillary pressure, which stimulates them to initiate rapid, shallow breathing;
hypotension and/or bradycardia
central receptors - CORRECT ANSWERS✓✓Located near the respiratory center and monitor arterial
blood indirectly by sensing changes in the pH of the CSF; as CO2 accumulates in the blood because of
lack of ventilation, it diffuses across the blood-brain barrier into the CSF
peripheral chemoreceptors - CORRECT ANSWERS✓✓Somewhat sensitive to changes in the pH and
instead are sensitive mostly to PaCO2 levels.
How would increase CO retention affect respiratory rate? - CORRECT ANSWERS✓✓Increased CO would
affect RR because it would increase the rate and depth of the breathes. ** double check this idk
Alveolar gas pressure - CORRECT ANSWERS✓✓If the gas pressure exceeds the blood pressure in the
capillary, the capillary collapses and blood flow ceases.
*perfusion exceeds ventilation in the bases and ventilation exceeds perfusion in the apices
