A child from a culture other than the nurse's has recently been diagnosed with leukemia. The child's sibling is expressing feelings of anger and guilt. This reaction by the sibling is very upsetting to the parents of the client.
 
  The nurse would explain to the family that the sibling's behavior is: 1. Abnormal and the sibling should be referred to a psychologist.
   2. Normal because the illness doesn't affect the sibling.
   3. Unexpected because the cancer is easily treated.
   4. Normal because the sibling is also affected, and anger and guilt are expected feelings.
