This report presents a comprehensive nursing care plan for a patient diagnosed with Diabetic Ketoacidosis (DKA). It begins with an initial rapid assessment using the ABC framework and details the assessment of vital signs, abnormal findings (such as elevated blood glucose, ketonuria, and academia), and fluid balance. The report then outlines three key nursing problems: risk of fluid volume deficit, risk of electrolyte imbalance, and risk of unstable blood glucose levels, each accompanied by related factors, goals of care, nursing interventions, and rationales. Patient education is addressed, emphasizing the importance of understanding the causes of DKA, medication management, healthy diet, lifestyle adjustments, and a sick day plan. Finally, the report discusses medication management, including the administration of sodium lactate and chloride solutions to address electrolyte imbalances and Actrapid insulin to manage glucose levels, providing details on the pharmacokinetics and potential side effects of each medication. This report aims to provide a detailed overview of the nursing care process for a patient with DKA, covering assessment, planning, implementation, and evaluation stages, ensuring that it supports student nurses in their studies.
