AACN PRACTICE EXAM QUESTIONS ANSWERS GRADED A+
hyperresonance and dullness over lung indicates... ANS >>
hyperresonance= air
dullness= fluid
decreasing the TV on ventilator will do what to co2? ANS >> increase
co2
The major effect of ARDS on lung tissue is ANS >> Decreased
compliance
Decreased compliance is related to alteration of lung endothelium and
vascular tissue. Pathophysiologic changes in lung vascular tissue and
increased lung enema 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 micro atelectasis.
Decreased surfactant
What is functional residual capacity? ANS >> amount of air remaining
in lungs after a normal tidal expiration
Clinical symptoms of hypoxic respiratory failure ANS >> Cyanosis'
restlessness delirium confusion hypertension tachycardia tachypnoea
decreased UO
What to do before deflating cuff ANS >> Suction oropharynx
What is plateau pressure and what does it reflect ANS >> 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, jived, LE enema and
ascites - symptoms of? ANS >> Pulmonary hypertension
, AACN PRACTICE EXAM
Signs of chronic bronchitis ANS >> Similar to r sided heart failure
Peripheral enema
Distended neck veins
Cyanosis
No signs of respiratory distress or dyspneal at rest
Tracheal deviation in hemothorax ANS >> Toward unaffected side
Early stage of status asthmaticus bag ANS >> Metabolic alkalosis
Loud machinery like heart murmur indicates? ANS >> Air embolism
What position would you put a patient with air embolism? ANS >>
Trendelenburg with left lateral decubitus tilt
Needle compression is for what?
Thoracentesis is for what? ANS >> Needle compression tension
pneumonia
Thoracentesis is to drain fluid from pleural space
Normal minute ventilation ANS >> 5-8
