1An adult patient in the emergency department has an arterial blood gas (ABG) drawn while breathing room air with the following results: pH 7.24, PaCO2 62 mmHg, PaO2 58 mmHg, HCO3- 25 mEq/L, and BE -1 mEq/L. Which of the following is the correct acid-base interpretation?
A.Partially compensated respiratory acidosis with moderate hypoxemia
B.Uncompensated metabolic acidosis with mild hypoxemia
C.Fully compensated respiratory acidosis with severe hypoxemia
D.Uncompensated respiratory acidosis with moderate hypoxemia
Explanation: The pH of 7.24 indicates acidemia (normal 7.35-7.45). The PaCO2 of 62 mmHg is elevated (normal 35-45 mmHg), indicating a respiratory cause. The HCO3- of 25 mEq/L is within the normal reference range (22-26 mEq/L), showing that renal compensation has not yet occurred. A PaO2 of 58 mmHg on room air reflects moderate hypoxemia (normal 80-100 mmHg). Therefore, this represents an uncompensated (acute) respiratory acidosis with moderate hypoxemia.
2A 68-year-old male with a 30-year history of severe chronic obstructive pulmonary disease (COPD) is admitted for acute bronchitis. His ABG on room air reveals: pH 7.36, PaCO2 64 mmHg, PaO2 55 mmHg, HCO3- 36 mEq/L, and BE +9 mEq/L. How should this acid-base status be categorized?
A.Uncompensated respiratory acidosis with acute hypoxemic failure
B.Fully compensated respiratory acidosis with moderate hypoxemia
C.Partially compensated metabolic alkalosis with hypoxemia
D.Combined mixed respiratory and metabolic alkalosis
Explanation: The arterial pH is 7.36, which is within the normal reference range (7.35-7.45) but on the acidotic side of 7.40. The PaCO2 is chronically elevated at 64 mmHg, and the kidneys have fully compensated by retaining bicarbonate to 36 mEq/L (normal 22-26 mEq/L). Because the pH has returned to normal range despite significant hypercapnia, this represents a fully compensated (chronic) respiratory acidosis, classic for advanced COPD.
3A respiratory therapist evaluates a patient in the intensive care unit who has a barometric pressure of 750 mmHg. The patient is receiving an FiO2 of 0.40. The ABG shows a PaCO2 of 40 mmHg and PaO2 of 150 mmHg. Assuming a respiratory quotient (R) of 0.8, what is the patient's calculated alveolar oxygen tension (PAO2)?
A.231 mmHg
B.241 mmHg
C.281 mmHg
D.300 mmHg
Explanation: The Alveolar Gas Equation is PAO2 = (PB - 47) x FiO2 - (PaCO2 / R). Here, PB = 750 mmHg, water vapor pressure = 47 mmHg, FiO2 = 0.40, PaCO2 = 40 mmHg, and R = 0.8. Calculation: PAO2 = (750 - 47) x 0.40 - (40 / 0.8) = (703 x 0.40) - 50 = 281.2 - 50 = 231.2 mmHg (approximately 231 mmHg).
4A patient with acute hypoxemic respiratory failure has a calculated PAO2 of 320 mmHg while receiving supplemental oxygen. The concurrent arterial blood gas shows a PaO2 of 80 mmHg. What is the calculated alveolar-arterial oxygen tension gradient [P(A-a)O2], and how is it interpreted?
A.40 mmHg, which is normal for an adult on oxygen
B.240 mmHg, which indicates significant V/Q mismatch or intrapulmonary shunt
C.400 mmHg, which indicates alveolar hypoventilation only
D.160 mmHg, which is typical for healthy high-altitude residents
Explanation: The alveolar-arterial oxygen gradient is calculated as P(A-a)O2 = PAO2 - PaO2. In this case, 320 mmHg - 80 mmHg = 240 mmHg. Normal P(A-a)O2 breathing room air is typically 5-15 mmHg in young adults (or approximately age/4 + 4), and on high FiO2 it generally remains below 100 mmHg. A gradient of 240 mmHg is markedly elevated, indicating impaired gas exchange from intrapulmonary shunting, diffusion impairment, or severe ventilation-perfusion mismatch.
5A mechanically ventilated patient with bilateral pulmonary infiltrates on chest radiography has an arterial blood gas showing PaO2 of 64 mmHg while on an FiO2 of 0.80 and PEEP of 10 cmH2O. According to the Berlin Definition, what is the PaO2/FiO2 ratio and corresponding ARDS severity category?
A.PaO2/FiO2 is 125, classifying the patient as moderate ARDS
B.PaO2/FiO2 is 80, classifying the patient as severe ARDS
C.PaO2/FiO2 is 160, classifying the patient as mild ARDS
D.PaO2/FiO2 is 51, classifying the patient as non-ARDS hypoxemia
Explanation: The PaO2/FiO2 ratio (P/F ratio) is calculated by dividing PaO2 by decimal FiO2: 64 / 0.80 = 80 mmHg. Under the Berlin Definition of ARDS with PEEP >= 5 cmH2O: Mild ARDS is P/F 201-300 mmHg, Moderate ARDS is P/F 101-200 mmHg, and Severe ARDS is P/F <= 100 mmHg. Because the P/F ratio is 80 mmHg, this condition is classified as severe ARDS.
6A respiratory therapist places a hypoxemic patient on a non-rebreathing mask with 100% oxygen. After 20 minutes, the repeat arterial blood gas reveals minimal improvement in PaO2 (rising from 48 mmHg to 54 mmHg). What physiological mechanism explains this refractory hypoxemia?
A.Severe alveolar hypoventilation responsive to bronchodilator therapy
B.Low ventilation-perfusion (V/Q) units that respond to supplemental oxygen
C.Diffusion defect caused by simple muscular fatigue
D.Significant true intrapulmonary shunting (V/Q = 0)
Explanation: Refractory hypoxemia is defined as a PaO2 that does not respond significantly to increases in FiO2. The hallmark mechanism of refractory hypoxemia is true intrapulmonary shunting (V/Q = 0), such as in severe atelectasis, dense consolidation, or ARDS, where blood traverses non-ventilated alveoli without picking up oxygen. In contrast, simple V/Q mismatch and hypoventilation respond promptly to supplemental oxygen.
7A firefighter rescued from an enclosed house fire presents with headache, nausea, and cherry-red lips. Pulse oximetry displays an SpO2 of 99%, but the patient is tachypneic. Which diagnostic test is essential to confirm the diagnosis?
A.Standard two-wavelength pulse oximetry trending over 1 hour
B.Transcutaneous oxygen tension (tcPO2) monitoring
C.Multiple-wavelength co-oximetry (hemoximetry) measuring carboxyhemoglobin
D.End-tidal capnography with volumetric dead space measurement
Explanation: Standard pulse oximeters measure light absorption at only two wavelengths (660 nm and 940 nm), across which carboxyhemoglobin (COHb) and oxyhemoglobin absorb light similarly, causing the pulse oximeter to falsely register COHb as oxyhemoglobin and display a falsely elevated SpO2. Multi-wavelength co-oximetry (hemoximetry) on an arterial or venous blood sample uses four or more distinct wavelengths to differentiate and measure oxyhemoglobin, deoxyhemoglobin, carboxyhemoglobin, and methemoglobin.
8A patient undergoing an upper endoscopy with topical benzocaine spray suddenly becomes cyanotic with chocolate-brown blood noted during arterial puncture. The pulse oximeter reads 85% despite high-flow oxygen, but arterial blood gas analysis shows a PaO2 of 240 mmHg. What condition is present, and what is the definitive antidote?
A.Carboxyhemoglobinemia; treated with hyperbaric oxygen therapy
B.Sulfhemoglobinemia; treated with fresh frozen plasma
C.Cyanide toxicity; treated with amyl nitrite
D.Methemoglobinemia; treated with intravenous methylene blue
Explanation: Topical anesthetics such as benzocaine or prilocaine can oxidize the ferrous iron (Fe2+) in hemoglobin to ferric iron (Fe3+), forming methemoglobin. Methemoglobin cannot bind oxygen and shifts the oxygen dissociation curve to the left. Methemoglobin exhibits equal light absorption at 660 nm and 940 nm, causing standard pulse oximeters to plateau at ~85% regardless of true saturation or high PaO2. The presence of cyanosis, chocolate-brown arterial blood, and normal/high PaO2 is classic. The treatment of choice is intravenous methylene blue (1-2 mg/kg).
9During continuous end-tidal carbon dioxide (PetCO2) monitoring of a mechanically ventilated trauma patient, the PetCO2 suddenly drops from 38 mmHg to 10 mmHg within two breaths, while peak inspiratory pressure remains unchanged. Which of the following is the most likely cause?
A.Development of an endotracheal cuff leak
B.Acute bronchospasm causing progressive expiratory air-trapping
C.Massive pulmonary embolism or acute severe loss of pulmonary perfusion
D.Malignant hyperthermia with accelerated cellular metabolism
Explanation: A sudden, precipitous drop in PetCO2 while ventilation continues (normal peak pressure) indicates an abrupt cessation of pulmonary perfusion, as seen in massive pulmonary embolism or cardiac arrest, creating massive alveolar dead space. Because unperfused alveoli contain no carbon dioxide, expired gas is diluted, causing PetCO2 to plummet.
10A patient with acute asthma exacerbation is connected to a capnograph. The capnogram displays a loss of the normal horizontal alveolar plateau (Phase III) and instead shows an upward-sloping, 'shark-fin' waveform. What physiological abnormality does this capnogram represent?
A.Unequal expiratory emptying rates and airway obstruction across lung units
B.Inspiratory valve incompetence on the mechanical ventilator
C.Spontaneous diaphragmatic efforts during mandatory exhalation
D.Excessive moisture and condensation within the sampling line
Explanation: The 'shark-fin' capnographic waveform is characteristic of obstructive airway disease (asthma, COPD, severe bronchospasm). Airway narrowing causes prolonged, uneven exhalation across lung units with varying time constants. Fast-emptying low-resistance units empty early, followed by slow-emptying high-resistance units with higher CO2 concentrations, eliminating the flat alveolar plateau and producing an upward slope.
