AACN practice questions with Correct
Answers
hyperresonace and dullness over lung indicates... - Correct Answer✔️✔️-hyperresonance= air
dullness= fluid
decreasing the TV on ventilator will do what to co2? - Correct Answer✔️✔️-increase co2
The major effect of ARDS on lung tissue is - Correct Answer✔️✔️-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.

,What is functional residual capacity? - Correct Answer✔️✔️-amount of air remaining in lungs after
a normal tidal expiration
Clinical symptoms of hypoxic respiratory failure - Correct Answer✔️✔️-Cyanosis' restlessness
delirium confusion hypertension tachycardia tachynpnea decreased UO

What is plateau pressure and what does it reflect - Correct Answer✔️✔️-Pressure applied to
airways and alveoli
Reflects airway resistance
Decrease would indicate an obstruction, bronchospasm, tube blockage, or biting

What position would you put a patient with air embolism? - Correct Answer✔️✔️-Trendenlenberg
with left lateral decubitus tilt
Needle compression is for what?
Thoracenetisis is for what? - Correct Answer✔️✔️-Needle compression tension pneumo
Thoracentesis is to drain fluid from pleural space
Normal minute ventilation - Correct Answer✔️✔️-5-8
What pa02/fi02 ratio is indicative of ARDS - Correct Answer✔️✔️-Less than 300
Criteria for passing spontaneous breathing trial - Correct Answer✔️✔️--Rapid shallow breathing
index of less than105 (RR/VT)
-pao2/fio2 ration over 150
-VT more than 5ml/kg
If tidaling in cheat tube stops what should you check for - Correct Answer✔️✔️-Obstruction,
clots, kinks
Purpose of PEEP in ARDS - Correct Answer✔️✔️-Increase alveolar recruitment
