Postoperative complications and difficulties present a significant challenge in healthcare, and their proper management is crucial for the successful recovery of patients. This analysis examines the main postoperative complications, including pain, constipation, urinary retention, infection, and anxiety. Pain is a common occurrence after surgery and requires careful monitoring and the application of appropriate interventions to ensure patient relief. To reduce pain intensity, nurses need to identify the causes of pain and apply pharmacological and nonpharmacological treatment methods. Constipation, which often arises due to reduced physical activity and fluid intake, also requires an active approach. Educating patients about the importance of physical activity and hydration, along with the use of laxatives when necessary, can significantly contribute to normalizing digestion. Urinary retention can cause additional discomfort and increase the risk of infections. Therefore, it is essential to monitor patients’ urination and implement methods that encourage normal urinary elimination. Infection, as a serious postoperative complication, necessitates strict hygiene and proper wound care to prevent bacterial infections. Anxiety in patients can further complicate recovery, and nurses need to provide emotional support and allow patients to express their fears and concerns. Educating patients about pain management, wound care, and physical activity is key to reducing the risk of complications and supporting a successful recovery. Documenting nursing diagnoses, including goals, interventions, and evaluations, ensures continuity of care and timely responses to changes in patients’ health status. This approach emphasizes the importance of individualized care and the continuous development of nurses’ skills.
