Acute Respiratory Care Nursing Questions Questions
Question 1 of 5
A patient with chronic obstructive pulmonary disease (COPD) is at risk for which complication?
Correct Answer: A
Rationale: COPD impairs gas exchange, leading to hypoxemia (low blood oxygen) due to airway obstruction and alveolar damage, not hyperoxia, bradycardia, or hypertension.
Question 2 of 5
Which oxygen delivery method provides the highest concentration?
Correct Answer: C
Rationale: A non-rebreather mask delivers up to 100% oxygen by preventing rebreathing exhaled air, exceeding nasal cannula (24-44%), simple mask (40-60%), or Venturi mask (24-50%).
Question 3 of 5
Which condition increases the work of breathing?
Correct Answer: A
Rationale: Pneumonia causes lung inflammation and consolidation, increasing resistance and the work of breathing, unlike hypertension, anemia, or diabetes, which affect circulation or metabolism.
Question 4 of 5
Which factor contributes to hypoxemia in acute respiratory distress syndrome (ARDS)?
Correct Answer: A
Rationale: ARDS causes alveolar collapse and fluid accumulation, impairing gas exchange and leading to hypoxemia, not high cardiac output, bronchodilation, or increased hemoglobin.
Question 5 of 5
Which condition is a risk factor for pulmonary embolism?
Correct Answer: A
Rationale: Dehydration increases blood viscosity, promoting clot formation and pulmonary embolism risk, more than hypotension, bradycardia, or fever.
