1 / 20

1. Which one of the following statements regarding coronary blood flow is INCORRECT?

2 / 20

2. Which one of the following statements regarding the use of bronchial blockers is FALSE?

3 / 20

3. A 66 year old man undergoes emergency coronary artery bypass grafting (CABG) following failed percutaneous coronary intervention for acute myocardial infarction.  In the immediate pre-operative period he has received both aspirin and clopidogrel.  There is significant generalised bleeding following weaning from bypass with reversal of heparin.  Thromboelastography (TEG) with kaolin and kaolin heparinase samples is normal. Which one of the following is the most appropriate course of action?

4 / 20

4. A patient with moderate to severe aortic regurgitation has a permanent pacemaker for symptomatic bradycardia. Preoperative 12-lead ECG shows paced ventricular rhythm with no P waves at 80 beats per minute. The patient has not attended pacemaker clinic in several years. During an emergency procedure at midnight the heart rate suddenly falls to 50 bpm (pacing spikes still seen), and the blood pressure falls despite several doses of ephedrine. Which one of the following options is best management in this situation?

5 / 20

5. A patient is being counselled prior to cardiac surgery. She is interested to know her risk of perioperative stroke.  All of the following are true except which one?

6 / 20

6. A 74-year-old woman is in theatre for an urgent repeat coronary artery bypass graft procedure following a myocardial infarction caused by late graft failure. Before sternotomy the rhythm deteriorates to ventricular fibrillation. Which one of the following statements regarding the immediate management of this situation is correct?

7 / 20

7. A young patient with a Fontan circulation presents for elective surgery. Which one of the following statements regarding the anaesthetic management of such a patient is INCORRECT?

8 / 20

8. A patient is fitted with a VVI pacemaker. Which one of the following is incorrect regarding the functions of this pacemaker?

9 / 20

9. A patient presents for emergency surgery.  They had an implantable pacemaker fitted some years ago in a different hospital, although they cannot remember the indication.  The device was last checked 6 months ago.  The patients ECG shows sinus rhythm.  Which one of the following statements regarding the pacemaker is true?

10 / 20

10. When considering your choice of anaesthetic for thoracic surgery, which ONE of the following operations is an absolute indication for using a double-lumen endotrachael tube?

11 / 20

11. A 68 year old gentleman returns from theatre following aortic valve repair and coronary artery bypass grafting.  In the first three hours his pleural and mediastinal drain outputs are 100 mL per hour.  He remains cardiovascularly stable.  Thromboelastography is performed.  The kaolin sample shows a prolonged R time, whereas the kaolin heparinase sample is normal.  Which of the following is the initial single best course of action?

12 / 20

12. Regarding the anaesthetic techniques available for one-lung ventilation (OLV) for a lung biopsy, which of the following statements is INCORRECT?

13 / 20

13. All of the following are direct determinants of cerebral perfusion during cardiopulmonary bypass except which one?

14 / 20

14. A patient undergoing on-pump cardiac surgery receives cardioplegia. Which one of the following does NOT correctly match a common component of cardioplegia solutions with its intended role?

15 / 20

15. You take over the care of a young man from Somalia whom your colleague has just induced for a laparoscopic appendicectomy. He has a past medical history of gout, gallstones and a ‘hole in the heart’ as a child. Initially he is tachycardic and hypertensive. This settles with opioid analgesia. Shortly after pneumoperitoneum is commenced he becomes hypotensive and progressively desaturates to 70%. Which one of the following represents the most likely cause?

16 / 20

16. A 76-year-old woman returns from theatre following mitral valve repair. She subsequently becomes haemodynamically unstable, and transoesophageal echocardiography shows systolic anterior motion (SAM) of the mitral valve leaflets. Which one of the following does NOT have a role in the treatment of the above condition?

17 / 20

17. You are anaesthetising a patient with a heart transplant for an elective non-cardiac procedure. He is otherwise well and the most recent echocardiogram shows good cardiac function. He becomes bradycardic with a rate of 35 beats per minute. There is mild associated hypotension and oxygen saturations are normal. Which one of the following is most likely to have the desired effect when administered intravenously?

18 / 20

18. Which one of the following is false regarding the cardiopulmonary bypass circuit?

19 / 20

19. Which one of the following patients undergoing procedures is appropriately matched with antibiotics to prevent infective endocarditis?

20 / 20
