The nurse is assisting with the care of a client. Exhibits Which of the following actions should the nurse assist with? (Click on the exhibit tabs for additional information about the client. There are six tabs that contain separate categories of data.)

A. Provide the client with ice chips: The client is on NPO status in preparation for surgery. Offering ice chips could increase the risk of aspiration or delay surgical procedures, so this action is not appropriate at this time. B. Discontinue nasogastric tube: The NG tube is necessary to decompress the stomach and relieve nausea from the small-bowel obstruction. Removing it before surgery or resolution of obstruction could worsen vomiting and distention, so discontinuation is not indicated. C. Reinforce preoperative teaching: Preoperative teaching helps reduce anxiety, improve cooperation, and prepare the client for what to expect during and after the exploratory laparotomy. This action is appropriate and supports client safety and understanding. D. Start the prescribed antibiotic: The prescription for Cefazolin is 2 g IV and is ordered "on call for surgery." This means the antibiotic should be administered just before the surgical procedure begins, to ensure therapeutic levels are present in the bloodstream when the incision is made.
