Answer to Question 1

C, E
Phenytoin is an antiseizure medication used to treat digoxin-induced dysrhythmias. Because di-goxin-induced dysrhythmias can be caused by hypokalemia, it is appropriate to evaluate the se-rum electrolyte levels. Amiodarone, diltiazem, and quinidine increase digoxin levels.

Answer to Question 2

D
An elevation of BUN and serum creatinine is an indication of nephrotoxicity, which occurs in 75 of patients taking cyclosporine. Hepatotoxicity would cause elevations in liver enzymes, not the BUN and creatinine. Infection would be associated with fever. Organ rejection of a renal transplant would cause elevation in the BUN and creatinine but also would cause tenderness at the graft site and fever.
