A patient reports seeing a frightening face on the wall of the dayroom. A nurse attempts to calm her by providing an explanation for the flawed perception of what she saw. The nurse would implement this strategy by stating:
 
  a. Let's see if anyone else has seen those frightening faces on the walls of the dayroom..
  b. The shadows of the tree outside the window make strange shapes on the dayroom walls..
  c. Have you ever seen frightening faces like that on the dayroom walls before today?
  d. Did someone in the dayroom tell you there were frightening faces on the walls?
