A nurse is providing preoperative teaching for a client. Which of the following outcomes should the nurse expect?

Choice A reason: Preoperative teaching aims to optimize recovery, not increase postoperative care duration. By clarifying procedures and expectations, teaching reduces complications, promoting shorter hospital stays, making this outcome contrary to the goals of effective preoperative education. Choice B reason: Reduced postoperative respiratory function is not a desired outcome. Preoperative teaching, including breathing exercises, aims to enhance respiratory function, preventing complications like atelectasis or pneumonia, making this outcome incorrect for the goals of preoperative education. Choice C reason: Preoperative teaching reduces postoperative anxiety by educating the client about the procedure, recovery, and expectations, lowering stress hormone release (e.g., cortisol). This promotes psychological preparedness, improving coping and recovery, making it a primary and expected outcome of effective teaching. Choice D reason: Increased postoperative pain is not an outcome of preoperative teaching. Teaching includes pain management strategies, aiming to reduce pain perception and improve comfort, making this outcome contrary to the educational goal of enhancing postoperative recovery and patient experience.
