1Which respiratory volume or capacity is defined as the volume of air remaining in the lungs at the end of a normal, quiet expiration?
A.Functional residual capacity (FRC)
B.Residual volume (RV)
C.Expiratory reserve volume (ERV)
D.Closing capacity (CC)
Explanation: Functional residual capacity (FRC) is the volume of gas remaining in the lungs at the end of normal tidal expiration, equal to the sum of expiratory reserve volume (ERV) and residual volume (RV). In healthy adults, it represents approximately 30 mL/kg (about 2.2 to 2.5 L) and acts as an essential oxygen reservoir during periods of apnea or induction of anesthesia. Induction of general anesthesia reduces FRC by approximately 15% to 20% due to loss of inspiratory muscle tone and cephalad displacement of the diaphragm.
2Which change causes a rightward shift of the oxyhemoglobin dissociation curve, facilitating the unloading of oxygen to peripheral tissues?
A.Decreased red blood cell 2,3-diphosphoglycerate (2,3-DPG)
B.Decreased arterial partial pressure of carbon dioxide (PaCO2)
C.Increased hydrogen ion concentration (decreased pH)
D.Decreased core body temperature
Explanation: A rightward shift of the oxyhemoglobin dissociation curve reflects reduced hemoglobin oxygen affinity, allowing oxygen to be released more readily to active peripheral tissues. This shift is caused by increased hydrogen ion concentration (acidosis/Bohr effect), increased PaCO2, elevated temperature, and increased levels of 2,3-DPG. In contrast, hypothermia, alkalosis, hypocarbia, and banked blood low in 2,3-DPG shift the curve leftward, increasing oxygen affinity.
3In West zone 1 of the lung, what is the physiological relationship between alveolar pressure (PA), pulmonary arterial pressure (Pa), and pulmonary venous pressure (Pv)?
A.Pa > Pv > PA
B.Pa > PA > Pv
C.PA > Pa > Pv
D.Pv > PA > Pa
Explanation: In West zone 1 (typically located at the lung apex under pathological conditions or during positive pressure ventilation), alveolar pressure exceeds pulmonary arterial pressure, which in turn exceeds pulmonary venous pressure (PA > Pa > Pv). Because alveolar pressure compresses the pulmonary microvasculature, pulmonary capillaries collapse and no blood flow occurs. This creates alveolar dead space (ventilation without perfusion), which increases significantly during hypovolemia or excessive positive end-expiratory pressure (PEEP).
4Which primary physiological stimulus triggers hypoxic pulmonary vasoconstriction (HPV) in pulmonary vascular smooth muscle?
A.Decreased mixed venous oxygen tension (PvO2)
B.Increased pulmonary arterial pulse pressure
C.Decreased systemic arterial oxygen saturation (SaO2)
D.Decreased alveolar oxygen tension (PAO2)
Explanation: Hypoxic pulmonary vasoconstriction (HPV) is an essential homeostatic reflex in which pulmonary arteriolar smooth muscle constricts in response to low alveolar oxygen tension (PAO2 < 60 mmHg). By diverting blood flow away from underventilated or atelectatic lung units toward well-ventilated regions, HPV preserves ventilation-perfusion matching and limits intrapulmonary shunt. Inhalational anesthetics at concentrations exceeding 1 to 1.5 MAC dose-dependently attenuate HPV.
5How is physiological dead space (VD/VT) quantified using the classic Enghoff modification of the Bohr equation?
A.(PaCO2 - PECO2) / PaCO2
B.(PECO2 - PaCO2) / PECO2
C.(PaO2 - PAO2) / PaO2
D.(PACO2 - PECO2) / PECO2
Explanation: The Enghoff modification of the Bohr equation calculates physiological dead space as VD/VT = (PaCO2 - PECO2) / PaCO2, where PaCO2 is the arterial carbon dioxide tension and PECO2 is the mixed expired carbon dioxide tension. In healthy conscious adults, VD/VT is approximately 0.25 to 0.33 (25% to 33% of tidal volume). Under general anesthesia and mechanical ventilation, physiological dead space typically increases to 0.40 to 0.50 due to equipment dead space, altered V/Q matching, and positive airway pressure.
6Which anatomical structure houses the primary central chemoreceptors that regulate ventilation in response to changes in hydrogen ion concentration?
A.Dorsal root ganglia of the cervical spinal cord
B.Carotid bodies located at the carotid bifurcations
C.Ventrolateral surface of the medulla oblongata
D.Aortic arch adventitia adjacent to the baroreceptors
Explanation: Central chemoreceptors are situated bilaterally on the ventrolateral aspect of the medulla oblongata beneath the pial surface. Carbon dioxide freely diffuses across the blood-brain barrier into cerebrospinal fluid (CSF), where it hydrates and dissociates via carbonic anhydrase into hydrogen ions and bicarbonate. The resulting decrease in CSF pH stimulates central chemoreceptors to increase minute ventilation; hydrogen ions themselves cannot readily cross the intact blood-brain barrier.
7What is the normal anatomical dead space in an upright healthy adult weighing 70 kg?
A.Approximately 50 mL
B.Approximately 100 mL
C.Approximately 150 mL
D.Approximately 250 mL
Explanation: Anatomical dead space comprises the conducting airways from the nose/mouth down to the terminal bronchioles where no gas exchange occurs. A reliable clinical rule of thumb is approximately 2 mL/kg of ideal body weight, which corresponds to roughly 150 mL in an average 70 kg adult. Endotracheal intubation decreases anatomical dead space by bypassing the upper airway, whereas breathing circuits and catheter mounts add mechanical dead space.
8Which clinical scenario causes closing capacity (CC) to exceed functional residual capacity (FRC) in the supine position, leading to dependent airway closure during tidal breathing?
A.Young athletic male breathing spontaneously in the upright position
B.Patient receiving continuous positive airway pressure (CPAP) of 10 cmH2O
C.Administration of high-dose intravenous bronchodilator therapy
D.Morbidly obese geriatric patient undergoing induction of general anesthesia
Explanation: Closing capacity (CC) increases progressively with advancing age, exceeding FRC in the supine position by roughly age 44 and in the upright position by age 66. In morbid obesity, FRC is markedly decreased due to excessive chest wall mass and elevated intra-abdominal pressure. When general anesthesia is induced, muscle relaxation causes further cephalad diaphragmatic shift, ensuring CC significantly exceeds FRC, which produces airway collapse, atelectasis, and severe V/Q mismatching.
9What is the primary cellular transport mechanism responsible for the rapid phase of carbon dioxide clearance in erythrocytes traversing pulmonary capillaries?
A.Chloride-bicarbonate anion exchanger (Band 3 / AE1 protein)
B.Sodium-potassium ATPase active transport pump
C.Sodium-hydrogen exchanger 1 (NHE-1)
D.Aquaporin-1 selective water channels
Explanation: In erythrocytes traversing systemic capillaries, CO2 is rapidly hydrated by carbonic anhydrase to H2CO3, which dissociates into H+ and HCO3-. Bicarbonate is transported out of the erythrocyte into plasma in exchange for chloride via the Band 3 anion exchanger 1 (AE1), a phenomenon known as the Hamburger phenomenon or chloride shift. In pulmonary capillaries, this process runs in reverse: bicarbonate enters erythrocytes in exchange for chloride, allowing carbonic anhydrase to regenerate CO2 for alveolar exhalation.
10What effect does breathing 100% inspired oxygen (FiO2 1.0) have on calculated intrapulmonary right-to-left true shunt fraction (Qs/Qt)?
A.It completely eliminates true shunt and normalizes the PaO2/FiO2 ratio
B.It fails to reverse arterial hypoxemia caused by fixed anatomical or true alveolar shunt
C.It increases pulmonary vascular resistance, thereby reversing the shunt flow
D.It doubles the dissolved oxygen content without altering hemoglobin saturation
Explanation: True intrapulmonary shunt (Qs/Qt) represents mixed venous blood that bypasses ventilated alveoli entirely, entering the left side of the circulation without undergoing gas exchange. Administering 100% oxygen cannot overcome true shunt because the supplemental oxygen never reaches the unventilated capillaries; this distinguishes true shunt from low V/Q mismatching, which readily responds to oxygen. Applying PEEP or recruitment maneuvers can recruit collapsed alveoli, converting shunt to functional gas exchange.
