Practice Questions with Detailed Rationales
Question 1
During rotor-wing transport, an intubated patient's endotracheal tube
cuff pressure increases significantly after climbing to 5,000 feet MSL.
Which gas law explains this physical change?
• A. Dalton's Law
• B. Boyle's Law
• C. Charles' Law
• D. Henry's Law
Correct Answer: B
Detailed Rationale: Boyle's Law states that pressure and volume are
inversely proportional at a constant temperature (𝑃1 𝑉1 = 𝑃2 𝑉2 ). As
ambient barometric pressure decreases during ascent, the volume of air
trapped inside the sealed endotracheal tube cuff expands, increasing
internal cuff pressure against the tracheal wall.
Question 2
A patient with severe chronic obstructive pulmonary disease (COPD) is
mechanically ventilated during flight. The flight paramedic notes
progressive hypotension and rising peak airway pressures. Which
ventilator-associated phenomenon is most likely occurring?
• A. Absorption atelectasis
, • B. Dynamic hyperinflation (Auto-PEEP)
• C. Pulmonary embolism
• D. Oxygen toxicity
Correct Answer: B
Detailed Rationale: Patients with COPD have prolonged expiratory
times. If the ventilator delivers subsequent breaths before exhalation is
complete, gas trapping occurs, leading to dynamic hyperinflation or
auto-PEEP. This increases intrathoracic pressure, compresses venous
return, and causes acute hypotension.
Question 3
Which vasoactive infusion is considered the first-line vasopressor of
choice for maintaining perfusion in septic shock refractory to fluid
resuscitation due to its potent alpha-1 and moderate beta-1 adrenergic
activity?
• A. Dopamine
• B. Phenylephrine
• C. Norepinephrine
• D. Vasopressin
Correct Answer: C
Detailed Rationale: Norepinephrine is the primary first-line vasopressor
for septic shock. It provides potent alpha-1 vasoconstriction to restore
vascular tone and moderate beta-1 inotropic support to maintain
cardiac output without excessive tachycardia.
Question 4
,A traumatic brain injury (TBI) patient has a monitored intracranial
pressure (ICP) of 22 mmHg and a mean arterial pressure (MAP) of 82
mmHg. What is the calculated cerebral perfusion pressure (CPP), and
how does it relate to adult target guidelines?
• A. CPP is 60 mmHg; it meets the minimum threshold of the target
range (60 to 70 mmHg).
• B. CPP is 104 mmHg; it is above the target range.
• C. CPP is 40 mmHg; it is too low.
• D. CPP is 110 mmHg; it is normal.
Correct Answer: A
Detailed Rationale: Cerebral perfusion pressure is calculated as 𝐶𝑃𝑃 =
𝑀𝐴𝑃 − 𝐼𝐶𝑃. Subtracting 22 mmHg from 82 mmHg yields a CPP of 60
mmHg. Brain trauma guidelines recommend maintaining a CPP
between 60 and 70 mmHg, making 60 mmHg the borderline minimum
acceptable value.
Question 5
A high-altitude mountaineer develops severe hypoxia despite high
concentrations of supplemental oxygen. The flight crew understands
that this form of hypoxia, caused by an inability of tissues to utilize
oxygen due to cellular poisoning (such as cyanide), is classified as:
• A. Hypoxic hypoxia
• B. Hypemic hypoxia
• C. Stagnant hypoxia
• D. Histotoxic hypoxia
, Correct Answer: D
Detailed Rationale: Histotoxic hypoxia occurs when cellular machinery is
poisoned (e.g., by cyanide or carbon monoxide affecting the electron
transport chain), preventing cells from utilizing the oxygen delivered to
them, regardless of arterial oxygen tension.
Question 6
A postpartum patient at 3 hours post-delivery experiences severe
postpartum hemorrhage due to uterine atony. After initial oxytocin
administration fails to control bleeding, which adjunct medication is
indicated to promote uterine contraction, provided the patient does not
have hypertension?
• A. Methylergonovine (Methergine)
• B. Labetalol
• C. Atropine
• D. Adenosine
Correct Answer: A
Detailed Rationale: Methylergonovine is an ergot alkaloid used for
refractory postpartum hemorrhage due to uterine atony. It causes
sustained tetanic contractions of the uterus but is strictly
contraindicated in patients with hypertension due to its potent
vasoconstrictive properties.
