  6. ECG is as follows :

  7. Identify the P wave, QRS complex, ST segment, and T wave. • What is the diagnosis?

  20. What other investigations would you request for?

  21. FBC as follows : • TWC 12.0 • Hb 7.5 g/dL • Plt 650 • What could be the causes of his anaemia? • How do we determine the cause of his anaemia?

  22. ABG as follows : • pH 7.30 • pCO2 3.9kPa • pO2 10.0 kPa • HCO3 16.0 mmol/L • How do you interpret the blood gases?

  23. ECG
