The Nurse Evaluates the Precolonoscopy Instruction as Effective When the Patient

The nurse evaluates the precolonoscopy instruction as effective when the patient says:

A) "I know that the lighted tube he will use will help the doctor look at my tumor and he might take a small piece of tissue to look at in the lab."
B) "I know that the light on the tube will help cure my cancer."
C) "I know the colonoscopy is very painful and embarrassing, and I hope no one sees me in that position."
D) "My daughter is coming in to see me today. I am glad to be looking forward to something pleasant."
