I remember with horror and embarrassment the first multiple-choice exam I wrote.  I didn’t think the students were taking my course all that seriously, so I decided to use the first exam to show just how substantive the content really was.  I wrote long, complicated stems and followed them with multiple answer options and various combinations of them.  And it worked.  Students did poorly on the exam.  I was pleased until I returned the test on what turned out to be one of the longest class periods of my teaching career.  I desperately needed the advice that follows here.
