1. Which of the following is the most appropriate initial action when a critically ill patient
presents with a sudden systolic blood pressure of less than 90 mmHg?
A. Increase FiO₂ to 100%
B. Administer a rapid isotonic crystalloid bolus
C. Start a norepinephrine infusion immediately
D. Perform a bedside transthoracic echocardiogram
☑ Correct Answer: B
☑ Explanation: A rapid fluid bolus is the initial step to evaluate volume responsiveness and
treat hypovolemic or early distributive shock before initiating vasopressors. Options A (oxygen)
and D (echocardiogram) are not the immediate priority, and C (vasopressors) should follow fluid
resuscitation if the patient remains hypotensive.
2. In the A-B-C-D-E primary assessment of a critically ill patient, the "C" component refers to:
,2
A. Comfort
B. Cardiac rhythm
C. Circulation
D. Capillary refill
☑ Correct Answer: C
☑ Explanation: "C" stands for Circulation, which focuses on assessing pulse quality, blood
pressure, and overall perfusion status. Options A, B, and D are incorrect as they do not represent
the standard A-B-C-D-E assessment framework.
3. The most reliable bedside method to confirm endotracheal tube placement is:
A. Auscultation of bilateral breath sounds
B. Observation of chest rise
C. End-tidal CO₂ detector waveform
D. Fogging of the endotracheal tube
☑ Correct Answer: C
☑ Explanation: Continuous capnography (end-tidal CO₂) provides objective, continuous
,3
confirmation of tracheal placement, even in low-cardiac-output states. Options A, B, and D are
less reliable and can be misleading.
4. Which arterial blood gas finding best indicates metabolic acidosis with respiratory
compensation?
A. pH 7.48, PaCO₂ 30 mmHg, HCO₃⁻ 24 mmol/L
B. pH 7.30, PaCO₂ 28 mmHg, HCO₃⁻ 15 mmol/L
C. pH 7.55, PaCO₂ 48 mmHg, HCO₃⁻ 32 mmol/L
D. pH 7.35, PaCO₂ 45 mmHg, HCO₃⁻ 24 mmol/L
☑ Correct Answer: B
☑ Explanation: Metabolic acidosis is indicated by a low pH and low HCO₃⁻. Respiratory
compensation is shown by a low PaCO₂ (hyperventilation). Option B shows pH 7.30 (acidemia),
HCO₃⁻ 15 (low), and PaCO₂ 28 (low, indicating compensation). Option A shows respiratory
alkalosis, C shows metabolic alkalosis, and D is normal.

5. Which of the following parameters may be a LATE sign of cardiovascular disturbance,
signaling failure of compensatory mechanisms?
A. Tachycardia
B. Bradycardia
C. Hypotension
D. Hypertension
☑ Correct Answer: C
☑ Explanation: Hypotension is a late sign of cardiovascular compromise, indicating that
compensatory mechanisms (tachycardia, vasoconstriction) have failed. Tachycardia is typically
an early compensatory response. Bradycardia and hypertension are not characteristic late signs
of shock.
6. Which of the following is one of the most important indicators of critical illness?
A. Respiratory acidosis
B. Metabolic acidosis
