1According to the Frank-Starling law of the heart, an increase in left ventricular end-diastolic volume produces which effect on stroke volume, up to a physiological limit?
A.A decrease in stroke volume
B.An increase in stroke volume
C.No change in stroke volume
D.A decrease followed by no change
Explanation: The Frank-Starling mechanism describes how increased ventricular filling (preload) stretches myocardial sarcomeres, increasing the number of actin-myosin cross-bridge interactions and the force of contraction, thereby increasing stroke volume.
2A patient has an oxygen consumption (VO2) of 250 mL/min, arterial oxygen content of 20 mL/dL, and mixed venous oxygen content of 15 mL/dL. Using the Fick principle, what is the estimated cardiac output?
A.2.5 L/min
B.5.0 L/min
C.10.0 L/min
D.12.5 L/min
Explanation: Fick principle: Cardiac output = VO2 / (arterial O2 content - venous O2 content). The arteriovenous difference is 20 - 15 = 5 mL/dL = 50 mL/L. CO = 250 mL/min / 50 mL/L = 5 L/min.
3Afferent signals from the carotid sinus baroreceptors, activated by increased arterial pressure, travel to the medulla predominantly via which cranial nerve?
A.Vagus nerve (X)
B.Glossopharyngeal nerve (IX)
C.Facial nerve (VII)
D.Hypoglossal nerve (XII)
Explanation: Carotid sinus baroreceptor afferents travel via the glossopharyngeal nerve (CN IX, specifically the carotid sinus nerve/Hering's nerve) to the nucleus tractus solitarius in the medulla. Aortic arch baroreceptors, by contrast, travel via the vagus nerve (CN X).
4In a ventricular myocyte action potential, phase 0 (rapid depolarisation) is primarily generated by which ionic current?
A.Slow inward calcium current
B.Fast inward sodium current
C.Delayed outward potassium current
D.Inward funny current (If)
Explanation: Phase 0 of the ventricular myocyte action potential is caused by rapid opening of voltage-gated fast sodium channels, producing a steep depolarisation. The calcium current sustains the plateau (phase 2), and potassium currents mediate repolarisation (phase 3).
5The spontaneous phase 4 depolarisation ('pacemaker potential') of sinoatrial node cells is largely attributable to which current?
A.Fast sodium current (INa)
B.L-type calcium current only
C.The 'funny' current (If), a mixed Na+/K+ current
D.Delayed rectifier potassium current (IK)
Explanation: Sinoatrial node automaticity arises mainly from the funny current (If), a hyperpolarisation-activated, cyclic-nucleotide-gated mixed Na+/K+ inward current, which gradually depolarises the cell toward threshold, followed by T-type and then L-type calcium currents that complete the upstroke.
6Which of the following is the best description of cardiac 'preload'?
A.The resistance the ventricle must overcome to eject blood
B.The degree of myocardial fibre stretch at end-diastole
C.The force of myocardial contraction independent of fibre length
D.The heart rate at rest
Explanation: Preload refers to the ventricular wall tension or myocardial fibre stretch at the end of diastole, commonly approximated clinically by end-diastolic volume or filling pressures. It is distinct from afterload, which is the resistance to ejection.
7Cardiac afterload is most directly determined by which of the following?
A.Right atrial pressure
B.Aortic input impedance and systemic vascular resistance
C.End-diastolic sarcomere length
D.Coronary perfusion pressure
Explanation: Afterload is the tension the ventricle must generate to eject blood against the resistance and impedance of the arterial system, chiefly systemic vascular resistance and aortic input impedance (including arterial compliance and wave reflection).
8A critically ill patient develops peripheral oedema. Which combination of Starling forces would most favour increased net fluid filtration into the interstitium?
A.Increased capillary hydrostatic pressure and decreased plasma oncotic pressure
B.Decreased capillary hydrostatic pressure and increased plasma oncotic pressure
C.Increased capillary hydrostatic pressure and increased plasma oncotic pressure
D.Decreased capillary hydrostatic pressure and decreased interstitial hydrostatic pressure
Explanation: Net capillary filtration is governed by the balance of hydrostatic and oncotic pressures (Starling's equation). Increased capillary hydrostatic pressure (e.g. from fluid overload) combined with decreased plasma oncotic pressure (e.g. hypoalbuminaemia) both push fluid out of the vessel into the interstitium, favouring oedema.
9Noradrenaline (norepinephrine), commonly used as a first-line vasopressor in septic shock, exerts its predominant vasoconstrictor effect via which receptor?
A.Beta-1 adrenoceptor
B.Beta-2 adrenoceptor
C.Alpha-1 adrenoceptor
D.Dopamine D1 receptor
Explanation: Noradrenaline has potent alpha-1 adrenoceptor agonist activity on vascular smooth muscle, causing vasoconstriction and increased systemic vascular resistance, along with modest beta-1 activity that supports cardiac contractility.
10Vasopressin used as a vasopressor in refractory vasodilatory shock acts principally via which receptor on vascular smooth muscle?
A.V1 receptor
B.V2 receptor
C.Oxytocin receptor
D.Angiotensin II type 1 receptor
Explanation: Vasopressin's vasoconstrictor effect is mediated by V1 receptors on vascular smooth muscle, which are Gq-coupled and increase intracellular calcium. V2 receptors, in contrast, are located in the renal collecting duct and mediate water reabsorption via aquaporin-2 insertion.

About the CICM First Part Exam

The CICM First Part Examination is a written and oral test of the basic sciences applied to the clinical practice of intensive care medicine. Trainees must pass it to progress from Phase 1 to Phase 2 of CICM training. The written component covers cardiovascular, respiratory, renal, nervous, endocrine, gastrointestinal, and other organ-system physiology, anatomy, measurement, and pharmacology as applied to ICU practice, tested across two 2.5-hour papers of MCQs and SAQs, followed by oral vivas for candidates who pass the written papers.

Assessment

The First Part Examination is held twice a year by the College of Intensive Care Medicine of Australia and New Zealand (CICM). The written component comprises two 2.5-hour papers, each with 50 multiple-choice questions and 10 short-answer questions (100 MCQs and 20 SAQs total). Candidates who pass both the MCQ and SAQ written components are invited to an oral component of eight ~10-minute cross-table vivas. This free bank covers the MCQ basic-sciences content only.

Time Limit

2.5 hours per written paper (5 hours total across both papers)

Passing Score

No fixed public percentage. The MCQ and SAQ pass marks are re-set each sitting using the Angoff method; recent sittings have set the MCQ pass mark around 58-65% and the SAQ pass mark around 48%. Both components must be passed to progress to the oral component.

Exam Fee

AU$5,780.00 (excluding GST), per the College's 2026 Fee Schedule. A 30% cancellation fee applies to withdrawals made after the application closing date, unless waived under a Special Consideration application. Confirm the current fee on the CICM website before applying. (College of Intensive Care Medicine of Australia and New Zealand (CICM))

CICM First Part Study Tips from Top Performers

1Prioritise the core basic sciences first: CICM specifies that they make up at least half of the MCQ content, while pharmacology is integrated across the syllabus.
2Work through the syllabus organ system by organ system, pairing each system's physiology with its relevant anatomy, measurement, and pharmacology rather than studying these as separate silos.
3Drill pharmacokinetic and pharmacodynamic principles (context-sensitive half-time, clearance, volume of distribution, receptor pharmacology) since they recur across every organ-system section of the syllabus.
4Time yourself on MCQ blocks to build the speed needed for roughly 50 minutes per 50-question paper, and read the College's published examiner reports from recent sittings to see how questions are actually asked.
