On Monday, Mrs. Kleinfelder calls your office. Darla, your receptionist, indicates that Mrs. Kleinfelder is very concerned about the condition of her daughter. You ask if the mother is still on the phone. Darla answers, "Yes." After talking to the mother you understand that her daughter, Sally, has been running a fever since last Monday. However, over the weekend she has complained of severe pain in her joints. You tell Mrs. Kleinfelder to bring her daughter to the office this afternoon and you will work her in.
