Before you start your rotation, you need to know these things:

1. Basic kidney anatomy and physiology (e.g., glomerular filtration, tubular function).
2. Common kidney diseases (e.g., chronic kidney disease (CKD), acute kidney injury (AKI), nephrotic syndrome).
3. Basic laboratory tests related to nephrology (e.g., serum creatinine, urinalysis, electrolytes, GFR).
4. Renal replacement therapies (e.g., dialysis, kidney transplant).
5. Pharmacology related to nephrology (e.g., diuretics, ACE inhibitors, immunosuppressants).
6. Risk factors and management of kidney diseases, especially diabetes and hypertension.

Before you start your rotation, read these topics:

1. Pathophysiology of chronic kidney disease (CKD) and its stages.
2. Causes, diagnosis, and management of acute kidney injury (AKI).
3. Nephrotic syndrome and glomerulonephritis: diagnosis, treatment, and complications.
4. The principles and indications for dialysis (hemodialysis and peritoneal dialysis).
5. Kidney transplantation: indications, evaluation, and immunosuppressive therapy.
6. Electrolyte imbalances (e.g., hyperkalemia, hyponatremia) and their management in nephrology.
7. The role of hypertension and diabetes in kidney disease and their management strategies.

During your rotation, carry these items:

1. Stethoscope, pen, and notebook.
2. A pocket guide for common nephrology conditions and treatments.
3. A folder for patient charts and notes.
4. Access to nephrology reference materials on dialysis and transplant protocols.
