1. Understand and explain the principles of fluid balance in the human body, particularly with respect to the stresses of surgery. 2. Demonstrate the ability to assess a patient's fluid status post-operative procedure, including the interpretation of clinical signs, urine output, and other relevant parameters. 3. Identify and describe the different types of drains and tubes commonly used post surgery, with the ability to manage and interpret the fluid output from these tools. 4. Evaluate the need for electrolyte monitoring in post-operative patients, recognize the signs of imbalance and implement appropriate interventions and treatments. 5. Apply learned knowledge in real-life scenarios; these include the immediate postoperative setting along with the prolonged management of critical care patients, with regards to reviving fluids and maintaining electrolyte balance.
