AACN practice questions with correct
answers
hyperresonace and dullness over lung indicates... - CORRECT ANSWERS
✔✔hyperresonance= air
dullness= fluid
decreasing the TV on ventilator will do what to co2? - CORRECT ANSWERS
✔✔increase co2
The major effect of ARDS on lung tissue is - CORRECT ANSWERS
✔✔Decreased compliance
Decreased compliance is related to alteration of lung endothelium and vascular
tissue. Pathophysiologic changes in lung vascular tissue and increased lung
edema contribute to the decrease in compliance. The end result is stiffness of
the fluid-filled non-aerated airways. There is an increase in capillary
permeability due to the release of cytokines and a decrease in functional
residual capacity due to pathophysiologic changes in the lung. The
inflammatory process of ARDS causes inactivation, destruction and decreased
production of surfactant. This leads to increased surface tension at the alveolar
air-fluid interface, which causes microatelectasis.
Decreased surfactant
,What is functional residual capacity? - CORRECT ANSWERS ✔✔amount of
air remaining in lungs after a normal tidal expiration
Clinical symptoms of hypoxic respiratory failure - CORRECT ANSWERS
✔✔Cyanosis' restlessness delirium confusion hypertension tachycardia
tachynpnea decreased UO
What to do before deflating cuff - CORRECT ANSWERS ✔✔Suction
orophayrnx
What is plateau pressure and what does it reflect - CORRECT ANSWERS
✔✔Pressure applied to airways and alveoli
Reflects airway resistance
Decrease would indicate an obstruction, bronchospasm, tube blockage, or
biting
Loud s2, systolic murmur over left eternal border, jvd, LE edema and ascites -
symptoms of ? - CORRECT ANSWERS ✔✔Pulmonary hypertension
Signs of chronic bronchitis - CORRECT ANSWERS ✔✔Similar to r sided heart
failure
Peripheral edema
Distended neck veins
Cyanosis
No signs of respiratory distress or dysnpea at rest
, Tracheal deviation in hemothorax - CORRECT ANSWERS ✔✔Toward
unaffected side
Early stage of status asthmaticus abg - CORRECT ANSWERS ✔✔Metabolic
alkalosis
Loud machinery like heart murmur indicates? - CORRECT ANSWERS ✔✔Air
embolism
What position would you put a patient with air embolism? - CORRECT
ANSWERS ✔✔Trendenlenberg with left lateral decubitus tilt
Needle compression is for what?
Thoracenetisis is for what? - CORRECT ANSWERS ✔✔Needle compression
tension pneumo
Thoracentesis is to drain fluid from pleural space
Normal minute ventilation - CORRECT ANSWERS ✔✔5-8
What pa02/fi02 ratio is indicative of ARDS - CORRECT ANSWERS ✔✔Less
than 300
Criteria for passing spontaneous breathing trial - CORRECT ANSWERS ✔✔-
Rapid shallow breathing index of less than105 (RR/VT)
