NURS 4750 EXAM 1 QUESTIONS WITH COMPLETE
SOLUTIONS
acute respiratory failure Correct Answers this can be ventilatory
failure, oxygenation failure, or a combo of both and is classified
by abnormal blood gas values
Agonal breathing Correct Answers gasping respiration -
abnormal pattern of breathing and brainstem relfex characterized
by gasping, labored breathing, accompanied by strange
vocalizations and myoclonus
airway resistance Correct Answers pressure difference between
mouth and alveoli, divided by airflow. Defined as the change in
transpulmonary pressure required to produce a unit flow of gas
through the airways of the lung
Anxiety Correct Answers a vague uneasy feeling, the source of
which is often nonspecific or unknown by the individual
Barotrauma Correct Answers damage to the lungs by positive
pressure
BiPAP Correct Answers Bi-level positive airway pressure-
newer form of pressure cycled ventilator in which the ventilator
provides a preset inspiratory pressure and an expiratory pressure
similar to PEEP
Carina Correct Answers the point at which the trachea branches
into the right and left mainstem bronchi
, causes of combined respiratory failure Correct Answers
abnormal lungs, chronic bronchitis, emphysema, cystic fibrosis,
someone having an asthma attack
causes of oxygenation respiratory failure Correct Answers
impaired diffusion of oxygen at alveolar level, right to left
shunting of blood in the pulmonary vessels, perfusion-
ventilation mismatch, breathing air with low oxygen levels, and
abnormal Hgb that fails to bind oxygen
causes of ventilatory respiratory failure Correct Answers
physical problem of the lungs or chest wall, defect in respiratory
control center in the brain, or poor function of the respiratory
muscles (esp diaphragm)
characteristics of brain death Correct Answers absent self
awareness
absent sleep wake cycles
no motor function or only reflex spinal movement
no evidence of suffering
no respiratory function
no eeg activity
no cerebral metabolism
no chance or neurological recovery
Combined respiratory failure Correct Answers this involves
hypoventilation.
contributing factors to ICU psychosis Correct Answers threats
of death, threat of survival, pain or discomfort, lack of sleep,
loss of autonomy, loss of control over environment, separation
