The nurse asks a 12-year-old girl if she is having pain. She
denies pain, even though she is lying on her left side holding her abdomen with
her knees flexed up to it. What might be some underlying factors leading the
child to deny her pain? How would the nurse go about assessing this child’s
pain?
