Q.5 A 5 year old boy is brought to the Emergency Room following a crushing injury. The ECG reveals peaked T waves, prolonged PR interval and widened QRS complexes. Which of the following treatments should be administered immediately?
(a) Sodium bicarbonate infusion
(b) Intravenous bolus procainamide

(d) Intravenous magnesium sulphate
ANS- (a) Sodium bicarbonate infusion
Tall T waves/prolonged PR interval/wide QRS complex indicates Hyperkalemia.
Sodium bicarbonate may assist in the lowering of serum potassium in hyperkalemia by alkalinizing systemic blood volume and causing the intracellular shift of potassium via hydrogen and potassium exchange.
