<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 hours40 mEq80 mEq100 mEq140 mEq  <response>: For causing a rise of potassium in blood by 1 mEqdl, 200 mEq of potassium supplementation is required. Since symptoms develops with serum potassium less than 3 mEqdl, the clinician should give sufficient potassium to rise upto 3 mEqdl intravenous route. Following this oral potassium supplement will suffice Hence mathematically speaking this patient requires approximately 0.7 mEqdl of potassium to rise in the blood leading to a requirement of 0.7x 200 140 mEq over 24 hours
