<prompt> A patient on amphotericin B has weakness and cramps. Serum potassium 2.3 mEqdl. Calculate the total parenteral potassium supplementation to be given to the patient over the next 24 hous?40mEq80mEq100mEq140mEq  <response>: Ans. is d i.e., 140 mEq o For causing a rise of potassium in blood by ImEqdl, 200 mEq of potassium supplementation is required.o Since symptoms develop with serum potassium less than 3 mEqdl, the clinician should give sufficient potassium to rise upto 3 mEqdl via intravenous route. Following this oral potassium supplement will sufficeo Hence mathematically speaking this patient requires approximately 0.7 mEqdl of potassium to rise in the blood leading to a requirement of0.7 200 140 mEq over 24 hours
