This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Fluids and Electrolyte Imbalance, Subject name: Medicine
A patient on amphotericin B has weakness and cramps. Serum potassium = 2.3 mEq/dl. Calculate the total parenteral potassium supplementation to be given to the patient over the next 24 hours 
Select and explain. 
A. 40 mEq, B. 80 mEq, C. 100 mEq, D. 140 mEq
D: 140 mEq
Answer: D: 140 mEq 
Explanation: For causing a rise of potassium in blood by 1 mEq/dl, 200 mEq of potassium supplementation is required. Since symptoms develops with serum potassium less than 3 mEq/dl, the clinician should give sufficient potassium to rise upto 3 mEq/dl intravenous route. Following this oral potassium supplement will suffice Hence mathematically speaking this patient requires approximately 0.7 mEq/dl of potassium to rise in the blood leading to a requirement of 0.7x 200 = 140 mEq over 24 hours
