Answers & Detailed Explanations
Question 1: Which of the following parameters may be a late sign of
cardiovascular disturbance signaling failure of the compensatory mechanisms?
A. Tachycardia
B. Bradycardia
C. Hypotension
D. Hypertension
CORRECT ANSWER: C. Hypotension
Rationale: Hypotension is a late sign of cardiovascular decompensation. Early
compensatory mechanisms include tachycardia and increased systemic vascular
resistance to maintain blood pressure. Once these fail, hypotension ensues,
indicating imminent cardiovascular collapse.
Question 2: What is the single most important indicator of critical illness?
A. Tachypnea
B. Bradycardia
C. Fever
D. Hypotension
CORRECT ANSWER: A. Tachypnea
Rationale: Tachypnea is often the earliest and most sensitive indicator of critical
illness. It reflects the body's attempt to compensate for metabolic acidosis,
hypoxemia, or impending respiratory failure.
Question 3: According to the FCCS course, the ABCDE approach prioritizes which
of the following sequences?
,A. Airway, Breathing, Circulation, Disability, Exposure
B. Airway, Breathing, Circulation, Drugs, Evaluation
C. Assessment, Breathing, Circulation, Disability, Exposure
D. Airway, Breathing, Chest, Disability, Evaluation
CORRECT ANSWER: A. Airway, Breathing, Circulation, Disability, Exposure
Rationale: The ABCDE approach is a systematic assessment prioritizing Airway,
Breathing, Circulation, Disability (neurologic status), and Exposure. This sequence
ensures immediate life threats are identified and managed in order of clinical
priority.
Question 4: Which of the following is a key indicator of critical illness often
reflecting tissue hypoperfusion or shock?
A. Respiratory acidosis
B. Metabolic acidosis
C. Elevated creatinine
D. Hyponatremia
CORRECT ANSWER: B. Metabolic acidosis
Rationale: Metabolic acidosis (e.g., elevated lactate, low bicarbonate) is a key
indicator of critical illness, often reflecting tissue hypoperfusion, shock, or sepsis.
It should guide diagnostic evaluation and resuscitation efforts.
Question 5: A patient in the ICU has a mean arterial pressure (MAP) of 55 mmHg
despite fluid resuscitation. What is the next step in management?
A. Continue observation
B. Start vasopressor therapy
C. Administer IV magnesium
D. Increase oxygen flow to 15 L/min
CORRECT ANSWER: B. Start vasopressor therapy
Rationale: MAP below 65 mmHg after adequate fluid resuscitation indicates the
need for vasopressors to maintain organ perfusion. Vasopressor therapy is
indicated to restore adequate mean arterial pressure when volume resuscitation
alone has failed.
,Question 6: A 60-year-old on a ventilator has a plateau pressure of 32 cm H₂O
and PEEP of 10 cm H₂O. What is the driving pressure?
A. 22 cm H₂O
B. 32 cm H₂O
C. 42 cm H₂O
D. 10 cm H₂O
CORRECT ANSWER: A. 22 cm H₂O
Rationale: Driving pressure is calculated as plateau pressure minus PEEP (32 - 10 =
22 cm H₂O). Driving pressure greater than 15–20 cm H₂O is associated with
increased mortality in ARDS patients.
Question 7: A patient after a motor vehicle accident has hypotension, distended
neck veins, and absent breath sounds on the right. What is the most likely
diagnosis?
A. Cardiac tamponade
B. Tension pneumothorax
C. Hemorrhagic shock
D. Massive pulmonary embolism
CORRECT ANSWER: B. Tension pneumothorax
Rationale: Tension pneumothorax presents with hypotension, jugular venous
distention, and absent breath sounds on the affected side. Cardiac tamponade
has muffled heart sounds, while hemorrhagic shock presents with flat neck veins.
Question 8: Which finding is most consistent with early distributive shock?
A. Cold, mottled extremities
B. Narrow pulse pressure
C. Warm, flushed skin
D. JVD with clear lungs
CORRECT ANSWER: C. Warm, flushed skin
Rationale: Distributive shock (sepsis, anaphylaxis, neurogenic) causes vasodilation
leading to warm extremities early in the course. Cold extremities occur late or in
, cardiogenic shock. Narrow pulse pressure suggests cardiogenic or hypovolemic
shock.
Question 9: A 45-year-old post-operative patient develops sudden dyspnea,
hypoxia, and tachycardia. Bedside echo shows right ventricular dilation. What is
the next best step?
A. CT pulmonary angiography
B. Heparin bolus and infusion
C. Thrombolytics for massive PE
D. Lower extremity Doppler
CORRECT ANSWER: C. Thrombolytics for massive PE
Rationale: An unstable patient with hypoxia and right ventricular dilation
suggesting massive pulmonary embolism requires thrombolytics if no
contraindication exists. CT angiography delays care in an unstable patient, and
heparin alone is insufficient for massive PE.
Question 10: Which PEEP strategy is recommended in ARDS?
A. Lowest possible PEEP
B. PEEP based on FiO₂ table (higher PEEP for severe hypoxemia)
C. Fixed PEEP of 5 cm H₂O
D. No PEEP if plateau pressure is normal
CORRECT ANSWER: B. PEEP based on FiO₂ table (higher PEEP for severe
hypoxemia)
Rationale: Higher PEEP for higher FiO₂ improves oxygenation while limiting
barotrauma. Low PEEP worsens atelectasis. PEEP is used even with normal
plateau pressures to maintain alveolar recruitment.
Question 11: A patient with intracranial hemorrhage has GCS 8, anisocoria, and
hypertension with bradycardia. What is the most likely condition?
A. Subdural hematoma
B. Uncal herniation (Cushing's triad)
C. Status epilepticus
D. Hypovolemic shock
