1Which of the following factors is associated with a decrease in the Minimum Alveolar Concentration (MAC) of volatile anesthetics?
A.Chronic alcohol abuse
B.Hypernatremia
C.Acute amphetamine ingestion
D.Hypothermia
Explanation: Hypothermia decreases the Minimum Alveolar Concentration (MAC) of volatile anesthetics by approximately 2-5% per degree Celsius decrease in core body temperature. Factors that decrease MAC generally depress central nervous system activity or neurotransmitter levels. Chronic alcohol abuse, hypernatremia, and acute amphetamine ingestion are associated with an increase in MAC.
2Which of the following features is characteristic of a Phase II neuromuscular block following succinylcholine administration?
A.Absence of fade during train-of-four (TOF) stimulation
B.Presence of post-tetanic facilitation
C.Reversibility with neostigmine during the early onset phase
D.Absence of fade during tetanic stimulation
Explanation: Phase II block is characterized by fade on TOF and tetanic stimulation, post-tetanic facilitation, and can occur after cumulative doses of succinylcholine (>4-5 mg/kg) or prolonged infusions. It resembles a non-depolarizing block.
3What is the primary mechanism of action of intravenous lipid emulsion (ILE) in the treatment of local anesthetic systemic toxicity (LAST)?
A.Direct antagonism of voltage-gated sodium channels
B.Creation of a lipid sink that extracts lipophilic local anesthetics from cardiac tissue
C.Enzymatic degradation of bupivacaine in the plasma
D.Up-regulation of beta-adrenergic receptors in the myocardium
Explanation: The lipid sink theory suggests that lipophilic local anesthetics (like bupivacaine) are sequestered into the lipid phase of the emulsion, lowering their free concentration in plasma and tissue, thereby removing them from cardiac tissue.
4Which of the following mechanisms best explains the sedative effect of dexmedetomidine?
A.GABA-A receptor facilitation in the cerebral cortex
B.NMDA receptor antagonism in the hippocampus
C.Agonism of presynaptic alpha-2 adrenoreceptors in the locus coeruleus
D.Antagonism of dopamine D2 receptors in the basal ganglia
Explanation: Dexmedetomidine is a highly selective alpha-2 adrenoceptor agonist. Its sedative action is mediated by presynaptic alpha-2 receptors in the locus coeruleus, which inhibits norepinephrine release, leading to a state of sedation resembling natural sleep.
5An increase in which of the following variables will shift the left ventricular end-diastolic pressure-volume relationship (EDPVR) upward and to the left (decreasing compliance)?
A.Acute myocardial ischemia
B.Administration of nitroprusside
C.Decreased intrathoracic pressure
D.Moderate exercise-induced tachycardia
Explanation: Acute myocardial ischemia impairs diastolic relaxation (an active process requiring ATP) and increases diastolic stiffness, shifting the EDPVR upward and to the left, which means a higher pressure is generated for any given volume (decreased compliance).
6In West Zone 1 of the lung, which of the following relationships between pressure variables exists?
A.Pulmonary venous pressure > Pulmonary arterial pressure > Alveolar pressure
B.Pulmonary arterial pressure > Alveolar pressure > Pulmonary venous pressure
C.Alveolar pressure > Pulmonary arterial pressure > Pulmonary venous pressure
D.Pulmonary arterial pressure > Pulmonary venous pressure > Alveolar pressure
Explanation: In Zone 1 (typically dead space), alveolar pressure (PA) exceeds pulmonary arterial pressure (Pa), which exceeds pulmonary venous pressure (Pv) (PA > Pa > Pv). This causes the pulmonary capillaries to collapse, preventing perfusion.
7A shift of the oxyhemoglobin dissociation curve to the right is associated with which of the following conditions?
A.Decrease in temperature
B.Decrease in carbon dioxide tension (PaCO2)
C.Increase in 2,3-diphosphoglycerate (2,3-DPG) concentration
D.Increase in pH (alkalosis)
Explanation: A rightward shift of the oxyhemoglobin curve decreases oxygen affinity, facilitating oxygen unloading to tissues. This is caused by increases in hydrogen ion concentration (low pH/acidosis), carbon dioxide tension (PaCO2), temperature, and 2,3-DPG.
8Renal blood flow (RBF) and glomerular filtration rate (GFR) are autoregulated within a mean arterial pressure (MAP) range of approximately:
A.40 to 100 mmHg
B.80 to 180 mmHg
C.100 to 200 mmHg
D.50 to 120 mmHg
Explanation: Renal autoregulation maintains a relatively constant RBF and GFR between a MAP of approximately 80 to 180 mmHg via the myogenic response and tubuloglomerular feedback. Outside this range, RBF becomes pressure-dependent.
9Which of the following drugs is a potent inhibitor of the Cytochrome P450 system and can prolong the duration of action of drugs metabolized by these enzymes?
A.Phenytoin
B.Rifampin
C.Cimetidine
D.Carbamazepine
Explanation: Cimetidine is a classic inhibitor of CYP450 enzymes. Inhibition of these enzymes reduces the clearance of co-administered drugs like warfarin, phenytoin, and some benzodiazepines, prolonging their effects.
10At which anatomical level do the trunks of the brachial plexus divide into anterior and posterior divisions?
A.As they pass through the scalene triangle
B.Posterior to the clavicle
C.In the axilla
D.At the lateral border of the first rib
Explanation: The three trunks of the brachial plexus divide into anterior and posterior divisions posterior to the clavicle. These divisions then reorganize into lateral, medial, and posterior cords as they enter the axilla.
