NURS 5315 PULMONARY EXAM 1 SAMPLE QUESTIONS
WITH CORRECT ANSWERS GRADED A+
What role do irritants play in restrictive lung diseases? - ✅✅Irritants such as
aspirated fluids or inhaled toxins, can cause bronchial inflammation, atelectasis,
and decreased compliance in the lungs.
A clinical measure used to assess the severity of oxygenation disorders, calculated
by subtracting arterial oxygen levels from alveolar oxygen levels. - ✅✅Alveolar-
arterial oxygen gradient
What characterizes hypoxemic respiratory failure? - ✅✅Reduced O2 in arterial
blood, typically with a PAO2 less than 50 mmHg.
What is a form of respiratory failure characterized by elevated CO2 in the blood
(>50mmHg) and acidosis (pH<7.25) - ✅✅Hypercapnic respiratory failure
What is the difference between acute lung injury and ARDS? - ✅✅Acute is
characterized by a PF ratio of <= than 200, indicating more severe lung damage
Phases of acute lung injury - ✅✅1. Exudative phase(inflammation and edema)
2. Proliferative phase (healing)
, 3. Fibrotic phase (chronic changes)
What is the common causes of acute lung injury and ARDS? - ✅✅Pneumonia
Sepsis
Aspiration
Trauma or Overdose
Indirect lung failure secondary conditions like multiple organ failure
What is pulmonary embolism - ✅✅Pulmonary embolism is the occulsion or
partial occlusion of a pulmonary artery caused by an embolus, typically a
dislodged thrombus
What is a physiological response where blood vessels constricts in areas of the
lung with low oxygen levels, leading to decreased blood flow and V/Q mismatch. -
✅✅Hypoxic Vasoconstriction
What is the common causes of pulmonary embolism? - ✅✅Common causes
include deep vein thrombosis (DVT), fat emboli, air bubbles from IV medications,
and amniotic fluid
