Rationale: The patient's presentation of severe headache, blurred vision, and fatigue, along with the laboratory findings of elevated white blood cell count, thrombocytosis, and JAK2 V617F mutation, are characteristic of essential thrombocythemia. This is a myeloproliferative neoplasm characterized by the clonal proliferation of megakaryocytes, leading to an increased platelet count. The JAK2 V617F mutation is commonly found in essential thrombocythemia and other myeloproliferative disorders. The symptoms of essential thrombocythemia can be related to the increased blood viscosity and risk of thrombosis due to the elevated platelet count.

These exercises are crucial to prevent postoperative complications such as atelectasis and pneumonia, which are common risks after surgery. Deep breathing exercises help to expand the lungs and improve ventilation, while coughing exercises help to clear secretions and prevent respiratory complications. By assisting the patient with these exercises preoperatively, the nurse can help optimize the patient's respiratory function and decrease the risk of complications during and after surgery. Administering aspirin, providing education about pain management, and obtaining informed consent are also important aspects of preoperative care, but assisting with deep breathing and coughing exercises is particularly essential for patients undergoing CABG surgery due to the increased risk of respiratory complications in this population.
