Question 6# Print Question

Regarding ACS which of ONE the following statements is TRUE?

A. Negative serial troponin excludes ACS
B. Troponin has a high early sensitivity for myocardial infarction
C. The ECG is the only investigation required to determine whether a patient requires emergency reperfusion
D. A chest X-ray (CXR) should be performed before thrombolysis in every patient


Question 7# Print Question

 Regarding ECG changes associated with ACS, which ONE of the following statements is TRUE?

A. 70% of patients with AMI have a diagnostic ECG
B. Pseudoinfarction patterns mimicking STEMI on an ECG may be secondary to pulmonary embolus (PE) and subarachnoid haemorrhage
C. Discordance of the QRS complex and ST segment or T wave in the left bundle branch block (LBBB) is suggestive of myocardial ischaemia
D. ST segment elevation of 1 mm in 2 or more contiguous chest leads meets reperfusion criteria


Question 8# Print Question

Regarding myocardial infarction, which ONE of the following statements is TRUE?

A. Anterior or anteroseptal myocardial infarction is the least common, has the worst prognosis and occurs secondary to occlusion of the left anterior descending artery
B. Inferior myocardial infarction is the most common infarction and may be associated with RV involvement and heart block
C. Lateral infarction occurs as a consequence of occlusion of posterior descending artery
D. Posterior infarction occurs as a consequence of occlusion of the posterior descending artery or occasionally from the circumflex artery in patients with dominant left-sided coronary circulation


Question 9# Print Question

Regarding contraindications to thrombolysis in STEMI, which ONE of the following statements is TRUE?

A. Known malignant intracranial neoplasm is a relative contraindication
B. Current use of anticoagulants is an absolute contraindication
C. Recent (within 4 weeks) internal bleeding (gastrointestinal tract or urinary tract) is an absolute contraindication
D. Chest pain with new left upper-limb weakness is an absolute contraindication


Question 10# Print Question

Regarding reperfusion therapy in AMI, which ONE of the following is TRUE?

A. Recent research has suggested that prehospital thrombolysis within 2 hours of symptom onset has superior outcomes compared with percutaneous coronary intervention, and similar outcomes if given within 4 hours of symptom onset
B. Early thrombolysis is as effective as percutaneous coronary intervention in patients with cardiogenic shock
C. Thrombolysis has the same risk of bleeding-related complications for all patients
D. The number needed to treat with thrombolytics for inferior STEMI to save one life is approximately 20
