SPUTUM BOWL TESTS
COMPILATION BUNDLE 2026 TEST
BANK COMPLETE QUESTIONS
SOLUTIONS GRADED A+
◉ What does a widened A-a gradient that improves with oxygen
suggest?
Answer: V/Q mismatch
◉ Which lung volume cannot be measured by simple spirometry?
Answer: Residual Volume (RV)
◉ What physiologic principle explains alveolar gas exchange?
Answer: Fick's Law
◉ What factors shift the oxyhemoglobin dissociation curve to the right?
Answer: Increased temperature, increased CO2, or acidosis
◉ Which gas law explains why increasing pressure decreases volume?
Answer: Boyle's Law
◉ What is the partial pressure of water vapor (PH2O) at body
temperature?
Answer: 47 mm Hg
, ◉ Which device delivers the most precise FiO2 for a spontaneously
breathing patient?
Answer: Air-entrainment (Venturi) mask
◉ What is the minimum flow rate for a non-rebreather mask?
Answer: 10-15 L/min
◉ Which ventilator alarm indicates a possible kinked ET tube?
Answer: High-pressure alarm
◉ Which organization awards the RRT credential?
Answer: National Board for Respiratory Care
◉ What is the first action when a patient on volume control triggers a
high-pressure alarm?
Answer: Check for obstruction or kinking
◉ What ventilator change will reduce auto-PEEP?
Answer: Increase expiratory time (by decreasing respiratory rate or tidal
volume)
◉ What therapy selectively reduces pulmonary vascular resistance
without systemic hypotension?
