Medical-Surgical Nursing Study Notes

Acute Kidney Injury (AKI) is a rapid loss of renal function characterized by an increase in serum creatinine and a decrease in urine output. It is categorized as prerenal, intrarenal, or postrenal based on the cause of the injury. Management focuses on identifying the underlying cause, managing fluid balance, and preventing electrolyte imbalances.

Study topic

Diabetes Mellitus is a chronic multisystem disease related to abnormal insulin production or utilization. It leads to hyperglycemia which, if uncontrolled, causes long-term damage to the vascular system and various organs. Nursing care involves monitoring glucose, administering medications, and providing extensive lifestyle education.

Study topic

Heart Failure is a clinical syndrome resulting from the heart's inability to pump sufficient blood to meet metabolic needs. It results in decreased cardiac output and increased venous pressure. Nursing management focuses on improving oxygenation, reducing fluid volume, and monitoring hemodynamic stability.

Study topic

Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable disease characterized by persistent respiratory symptoms and airflow limitation. It is primarily caused by significant exposure to noxious particles or gases, most commonly tobacco smoke. Nursing care involves optimizing gas exchange, clearing secretions, and preventing exacerbations.

Study topic

A Cerebrovascular Accident (CVA) or stroke occurs when blood flow to the brain is interrupted, leading to brain cell death. It is a medical emergency that requires rapid identification and intervention to minimize permanent disability. Nursing priorities include maintaining the airway, monitoring neurologic status, and preventing complications of immobility.

Study topic

Perioperative Nursing encompasses the care of the surgical patient before, during, and after an operative procedure. It requires a high level of vigilance to prevent complications such as infection, hemorrhage, or respiratory distress. The nurse acts as a patient advocate throughout the entire surgical experience.
