Mr. Jones, a 50-year-old professor, is 5 hours post laparoscopic cholecystectomy. He is alert and oriented. His physical assessment is within normal limits, including active bowel sounds and a soft, slightly tender abdomen. He is sipping on clear liquids and conversant. The nurse is performing the final assessment and providing discharge patient education. Mr. Jones states he feels a little tired because of all the excitement about going home and feeling so good after surgery. While checking his vital signs for the discharge form, you notice that his pulse is 110 beats/min and irregular compared to the 86-90 beats/min regular pulse that he had been having since surgery. Mr. Jones states his higher pulse just reflects his excitement; he feels great, and his wife is waiting in the car at the patient discharge area for him.
