A nurse is preparing to administer insulin to a child who's just been diagnosed with type 1 diabetes. When the child's mother stops the nurse in the hall, she's crying and anxious to talk about her son's condition. The nurse's best response is:

"If you'll wait in your son's room, the physician will talk with you as soon as he's free."

"Everything will be just fine. I'll be back in a minute and then we can talk."

"I can't talk now. I have to give your son his insulin as soon as possible."

"I'm going to give your son some insulin. Then I'll be happy to talk with you."
