Are NCLEX question peer reviewed?

My wife is graduating from nursing school this December and will be taking the NCLEX RN in Jan. She is taking a mandatory Kaplan review, and many of the questions are in her opinion inane, and contradictory. For example the Kaplan instructor had a sample question involving notifying the Dr. which she said will never be the correct answer on the NCLEX. However, about fourteen questions later (according to my wife) the correct answer involved notifying a physician.
Another situation involved delegating a task to an LPN. The Kaplan instructor said that you will never delegate changing a sterile dressing to an LPN (even though LPN’s do sterile dressings all day long in the real world at almost every facility), however on one of the questions delegating a sterile dressing change to an LPN was the correct choice! Who writes these questions and are the peer reviewed to the same extent as MCAT, SAT and ACT questions? Also, what is considered to be “the protocol” for which correct NCLEX actions are based against since doing some of the actions which are correct would cause you to lose your RN license in the real world.
