Answers & Rationales
Question 1
According to Dalton's Law, what happens to the total barometric
pressure and the partial pressure of individual gases as an aircraft
ascends to higher altitudes?
• A. Total barometric pressure and individual partial pressures
decrease proportionally.
• B. Partial pressures increase while total pressure decreases.
• C. Total pressure remains constant while gas concentrations
change.
• D. Gases condense into liquid state.
Correct Answer: A
Detailed Rationale: Dalton's Law of partial pressures states that the
total pressure exerted by a mixture of gases is equal to the sum of the
partial pressures of each individual gas. As altitude increases and total
barometric pressure decreases, the partial pressure of each gas in the
mixture decreases proportionally.
Question 2
,When performing rapid sequence induction (RSI) on a trauma patient in
hemorrhagic shock, why is ketamine often the preferred induction
agent?
• A. It causes profound myocardial depression and vasodilation.
• B. It stimulates the sympathetic nervous system, helping to
preserve heart rate and blood pressure.
• C. It lowers intracranial pressure instantly by dissolving blood.
• D. It acts exclusively as a long-acting skeletal muscle relaxant.
Correct Answer: B
Detailed Rationale: Ketamine is a dissociative anesthetic that stimulates
central sympathetic outflow, leading to an increase in circulating
catecholamines. This unique property helps maintain or elevate heart
rate and blood pressure, making it useful in hemodynamically
compromised or hypovolemic trauma patients.
Question 3
A patient presents with profound hypotension and bradycardia
following an intentional overdose of metoprolol. Which
pharmacological agent is considered the specific first-line antidote?
• A. Glucagon
• B. Atropine sulfate alone
• C. Protamine sulfate
• D. Flumazenil
Correct Answer: A
,Detailed Rationale: Glucagon activates adenylate cyclase via a non-beta-
adrenergic mechanism, increasing intracellular cyclic AMP, bypassing
beta-blockade, and restoring myocardial contractility and heart rate in
severe beta-blocker overdose.
Question 4
What is the primary lung-protective ventilation strategy recommended
for a mechanically ventilated patient with acute respiratory distress
syndrome (ARDS)?
• A. Low tidal volume ventilation (4 to 6 mL/kg of ideal body weight)
with strict monitoring of plateau pressures.
• B. High tidal volume ventilation (12 to 15 mL/kg) to maximize
alveolar recruitment.
• C. Elimination of positive end-expiratory pressure (PEEP) entirely.
• D. Constant high-pressure continuous positive airway pressure
without support.
Correct Answer: A
Detailed Rationale: Lung-protective ventilation in ARDS utilizes low tidal
volumes (4 to 6 mL/kg of ideal body weight) and limits plateau
pressures below 30 centimeters of water to prevent volutrauma,
barotrauma, and ventilator-induced lung injury.
Question 5
Which clinical findings classically distinguish neurogenic shock from
hypovolemic shock in a trauma patient with a high cervical spinal cord
injury?
, • A. Hypotension accompanied by bradycardia and warm, dry skin.
• B. Tachycardia, hypertension, and cold, clammy skin.
• C. Tachycardia and delayed capillary refill.
• D. Elevated systemic vascular resistance and pale skin.
Correct Answer: A
Detailed Rationale: Neurogenic shock disrupts sympathetic pathways,
causing loss of vascular tone (vasodilation) and unopposed
parasympathetic tone. This results in hypotension paired with
paradoxical bradycardia and warm, flushed skin due to peripheral
pooling, unlike the tachycardia and cool skin seen in hypovolemia.
Question 6
In a contemporary Massive Transfusion Protocol (MTP) for severe
traumatic hemorrhage, what is the standard initial ratio target for
plasma, platelets, and packed red blood cells?
• A. 1 unit of plasma to 1 unit of platelets to 1 unit of packed red
blood cells (1:1:1 ratio)
• B. 10 units of packed red blood cells to 1 unit of plasma
• C. 5 units of platelets to 1 unit of red cells exclusively
• D. Pure crystalloids without blood products
• Correct Answer: A
Detailed Rationale: Modern damage control resuscitation utilizes a
balanced 1:1:1 ratio of plasma, platelets, and packed red blood cells to
mimic whole blood, prevent dilutional coagulopathy, and reduce
mortality in massive hemorrhage.
