The Iraqi Board of Anesthesia & Intensive Care (IBMS/MOHESR) qualification involves a 4-year residency assessed by the Primary Written Exam (end of Year 1; two 80-MCQ papers, 90 mins each), Mid-Study OSPE (Year 3; 10 slides), and Final Examination (end of Year 4; two 80-MCQ papers, OSCE, oral viva, and dissertation defense). Pass criteria require 60% per paper and a 70% aggregate mean. This independent 100-question MCQ practice bank supports preparation for the theoretical written papers of Part 1 and Part 2; it is not a clinical OSCE simulation or a substitute for accredited residency training.

1Which respiratory volume or capacity is defined as the volume of gas remaining in the lungs at the end of a normal, quiet expiration?
A.Functional residual capacity (FRC)
B.Residual volume (RV)
C.Expiratory reserve volume (ERV)
D.Closing capacity (CC)
Explanation: Functional residual capacity (FRC) is the volume of gas remaining in the lungs at the end of normal tidal expiration, equal to the sum of expiratory reserve volume (ERV) and residual volume (RV). In healthy adults, it represents approximately 30 mL/kg (about 2.2 to 2.5 L) and acts as an essential oxygen reservoir during periods of apnea. Induction of general anesthesia reduces FRC by approximately 15% to 20% due to loss of inspiratory muscle tone and cephalad displacement of the diaphragm.
2Which physiological change causes a rightward shift of the oxyhemoglobin dissociation curve, promoting oxygen release to peripheral tissues?
A.Decreased red blood cell 2,3-diphosphoglycerate (2,3-DPG)
B.Increased hydrogen ion concentration (decreased pH)
C.Decreased arterial partial pressure of carbon dioxide (PaCO2)
D.Decreased core body temperature (hypothermia)
Explanation: A rightward shift of the oxyhemoglobin dissociation curve reflects decreased hemoglobin oxygen affinity, allowing oxygen to be unloaded more readily to metabolically active tissues. This shift is induced by increased hydrogen ion concentration (acidosis/Bohr effect), hypercapnia (elevated PaCO2), hyperthermia, and elevated 2,3-DPG levels. Conversely, hypothermia, alkalosis, hypocapnia, and banked blood depleted of 2,3-DPG cause a leftward shift.
3Mixed venous blood entering the pulmonary capillary is simultaneously oxygenated and stripped of carbon dioxide. Which property of haemoglobin explains why the act of oxygenation itself promotes carbon dioxide unloading in the lung, and why administering a high inspired oxygen concentration can raise PaCO2 in a patient with severe chronic hypercapnia?
A.Oxygenated haemoglobin is a weaker proton acceptor and forms carbamino compounds less readily, so the carbon dioxide dissociation curve shifts downward and to the right (Haldane effect)
B.Oxygenated haemoglobin binds 2,3-diphosphoglycerate more avidly, displacing bicarbonate out of the erythrocyte
C.Oxygenation inactivates erythrocyte carbonic anhydrase, preventing bicarbonate from being reconverted to carbon dioxide
D.Oxygenation abolishes the chloride (Hamburger) shift by closing the band 3 anion exchanger in the red cell membrane
Explanation: The Haldane effect is the reciprocal of the Bohr effect. Deoxygenated haemoglobin is a better proton acceptor and forms carbamino compounds with carbon dioxide more readily than oxygenated haemoglobin, so at any given PCO2 venous blood carries appreciably more carbon dioxide than arterial blood. When haemoglobin is oxygenated in the pulmonary capillary it releases protons, which drive bicarbonate back through carbonic anhydrase to carbon dioxide and water, and it simultaneously releases carbamino-bound carbon dioxide. Clinically, giving a high inspired oxygen concentration to a patient with severe chronic hypercapnia raises PaCO2 partly through this mechanism (oxygenated haemoglobin releases carbon dioxide into the plasma) and partly by releasing hypoxic pulmonary vasoconstriction and increasing dead space, in addition to any reduction in hypoxic respiratory drive.
4What is the primary physiological stimulus that initiates hypoxic pulmonary vasoconstriction (HPV)?
A.Decreased mixed venous oxygen tension (PvO2)
B.Decreased systemic arterial oxygen saturation (SaO2)
C.Increased pulmonary artery pulse pressure
D.Decreased alveolar oxygen tension (PAO2)
Explanation: Hypoxic pulmonary vasoconstriction (HPV) is an autoregulatory mechanism triggered primarily by a drop in alveolar oxygen tension (PAO2 < 60 mmHg) rather than systemic hypoxemia. By constricting pre-capillary pulmonary arterioles supplying underventilated or atelectatic lung units, HPV redirects perfusion to well-ventilated alveoli, thereby limiting right-to-left transpulmonary shunt. Volatile inhalational anesthetics at concentrations above 1 to 1.5 MAC dose-dependently inhibit HPV.
5During volume-controlled mechanical ventilation, how is static respiratory system compliance (Cstat) calculated?
A.Tidal volume / (Plateau pressure - PEEP)
B.Tidal volume / (Peak inspiratory pressure - PEEP)
C.(Peak inspiratory pressure - Plateau pressure) / Inspiratory flow rate
D.Plateau pressure / (Tidal volume + PEEP)
Explanation: Static compliance (Cstat) reflects the elastic recoil of both the lung parenchyma and the chest wall under zero-flow conditions, calculated as: Cstat = Tidal Volume / (Plateau Pressure - PEEP). In contrast, dynamic compliance (Cdyn = Tidal Volume / [Peak Pressure - PEEP]) incorporates both tissue elastance and airway resistance. A drop in static compliance with preserved peak-to-plateau gradient points to worsening pulmonary elastance (e.g., ARDS, pulmonary edema, or pneumothorax).
6Which mathematical equation uses arterial carbon dioxide tension (PaCO2) and mixed expired carbon dioxide tension (PECO2) to calculate physiological dead space (VD/VT)?
A.Alveolar gas equation
B.Bohr equation modified by Enghoff
C.Fick principle equation
D.Henderson-Hasselbalch equation
Explanation: The Enghoff modification of the Bohr equation calculates physiological dead space fraction as: VD/VT = (PaCO2 - PECO2) / PaCO2. The original Bohr equation utilized alveolar CO2 (PACO2), which is technically difficult to obtain directly; Enghoff substituted arterial PaCO2 on the premise that alveolar and arterial PCO2 equilibrate in healthy lung units. In healthy resting adults, VD/VT is approximately 0.20 to 0.33, but it rises substantially during general anesthesia and mechanical ventilation.
7On the Wiggers diagram of the cardiac cycle, which mechanical event immediately follows closure of the mitral valve?
A.Rapid ventricular ejection
B.Isovolumetric relaxation
C.Isovolumetric contraction
D.Diastolic diastasis
Explanation: Closure of the mitral valve (and tricuspid valve) marks the onset of ventricular systole and generates the first heart sound (S1). Immediately following atrioventricular valve closure, both the AV valves and the semilunar valves are closed; ventricular pressure rises steeply without any change in ventricular volume, defining the phase of isovolumetric contraction. Once left ventricular pressure exceeds aortic diastolic pressure, the aortic valve opens, initiating rapid ventricular ejection.
8According to the Frank-Starling law of the heart, what is the primary determinant of myocardial stroke volume in the normal physiological range?
A.Systemic vascular resistance (afterload)
B.Parasympathetic vagal tone
C.Peak systolic aortic pressure
D.End-diastolic sarcomere length (preload)
Explanation: The Frank-Starling mechanism states that the force of myocardial contraction is directly proportional to the initial resting length of the muscle fibers, known clinically as preload or end-diastolic volume. Stretching myocardial sarcomeres toward their optimal operating length (~2.2 micrometers) increases myofilament calcium sensitivity and cross-bridge formation, yielding a greater stroke volume on subsequent contraction. Excessive overstretching, as seen in end-stage dilated heart failure, leads to a flattened or descending curve.
9Which ion channel current is primarily responsible for the rapid phase 0 depolarization of ventricular myocardial contractile cells?
A.Inward fast sodium current (INa)
B.Inward L-type calcium current (ICa-L)
C.Delayed rectifier potassium current (IKr)
D.Hyperpolarization-activated pacemaker current (If)
Explanation: Phase 0 rapid depolarization in ventricular and atrial myocytes, as well as the His-Purkinje conduction system, is mediated by a massive, voltage-gated inward influx of sodium ions through fast sodium channels (INa). This is distinct from nodal pacemaker cells (SA and AV nodes), where phase 0 depolarization is slower and mediated primarily by inward L-type calcium channels (ICa-L). Class I antiarrhythmic agents and local anesthetics block these fast INa channels.
10During which phase of the cardiac cycle does the majority of left ventricular coronary blood flow occur, and what determines coronary perfusion pressure (CPP)?
A.Systole; CPP = Aortic systolic pressure - Central venous pressure
B.Diastole; CPP = Aortic diastolic pressure - Left ventricular end-diastolic pressure
C.Systole; CPP = Mean arterial pressure - Pulmonary capillary wedge pressure
D.Diastole; CPP = Mean arterial pressure - Left ventricular peak systolic pressure
Explanation: Because high intramyocardial tissue pressure during left ventricular systole compresses subendocardial vessels, approximately 80% of left ventricular coronary perfusion occurs during diastole. Left ventricular coronary perfusion pressure (CPP) is calculated as aortic diastolic pressure minus left ventricular end-diastolic pressure (LVEDP). Tachycardia profoundly jeopardizes coronary perfusion by disproportionately shortening diastolic filling time while increasing myocardial oxygen demand.

About the Iraqi Board Anesthesia Exam

The Fellowship of the Iraqi Board for Medical Specializations in Anesthesia & Intensive Care (F.I.B.M.S.) is the national postgraduate medical qualification awarded by the Iraqi Board for Medical Specializations (IBMS), operating under the Ministry of Higher Education and Scientific Research (MOHESR). The four-year curriculum provides comprehensive residency training across core surgical specialties, subspecialty anesthesia (cardiac, thoracic, neuroanesthesia, pediatric, obstetric, orthopedic, and trauma), pain medicine, and critical care medicine (adult, pediatric, and coronary care units). Important disclosure: The complete FIBMS credential requires structured clinical residency training, an approved scientific dissertation, OSPE slides, and structured clinical OSCE/oral viva stations, which cannot be simulated by multiple-choice questions. This 100-question multiple-choice practice bank is an independent English-language educational study resource designed to reinforce theoretical knowledge and decision-making for the Part 1 (Primary) and Part 2 (Final Written) exams. It is not an official IBMS examination, does not provide OSCE stations, and is not a substitute for formal accredited clinical residency training.
