Which of the following medication may increase LN's potassium?
Lisinopril may increase LN's potassium. One of the warnings/precautions of lisinopril is hyperkalemia. ACE inhibitors block the formation of circulating angiotensin II, which can lead to a decrease in aldosterone secretion that can result in an increase in potassium. Risk factors for hyperkalemia while taking lisinopril include renal impairment, diabetes, and concomitant use of potassium-sparing diuretics, potassium
supplements and/or potassium containing salts. Potassium should be monitored closely when taking any of the other agents listed. Hyperkalemia is not listed in the warnings/precautions section for the other medications.

Famotidine and Metoclopramide would need to be adjusted for poor renal function. Since his CrCl is less than 50, famotidine would need to be adjusted by decreasing the dose by 50% or increasing the interval to every 36 to 48 hours. Metoclopramide would also need to be adjusted by 50% of the normal dose since his CrCl is less than 40. ACEInhibitors and ARBs should be held if serum K is greater than 5.6 or there is a rise in serum creatinine greater than 30% after initiation.
