A nurse is providing discharge education to a client who has valvular heart disease and peripheral vascular disease. Which of the following should the nurse include in the teaching about valvular heart disease?

A. Decrease sedation: Decreasing sedation may help reduce intracranial pressure (ICP) by allowing the client to have a more responsive level of consciousness. However, it is not a direct treatment for brain herniation. Sedation reduction should be done cautiously to prevent agitation and further increases in ICP.

B. Hyperventilate the client: Hyperventilation is a temporary intervention used to reduce intracranial pressure by inducing cerebral vasoconstriction, which decreases cerebral blood flow and intracranial volume. However, it is typically reserved for acute situations and is not considered a definitive treatment for brain herniation. Prolonged or excessive hyperventilation can lead to cerebral ischemia and should be used cautiously.

C. Lower blood pressure: Lowering blood pressure may help reduce cerebral perfusion pressure, which can mitigate the risk of further brain injury during herniation. However, lowering blood pressure alone is not a direct treatment for brain herniation. It may be part of the overall management strategy to prevent secondary injury.

D. Reduce the temperature in the room: Reducing the temperature in the room, or therapeutic hypothermia, is sometimes used in the management of elevated intracranial pressure and brain injury. Lowering body temperature can reduce metabolic demands and cerebral edema, thereby lowering intracranial pressure. However, it is not a direct treatment for brain herniation and should be implemented cautiously to prevent complications such as shivering and hypotension.

A. Septal myectomy: Septal myectomy is a surgical procedure primarily used to treat hypertrophic cardiomyopathy (HCM), not atrial fibrillation. It involves removing a portion of the thickened septal wall in the heart to improve blood flow.

B. Synchronized electrical cardioversion: Synchronized electrical cardioversion is a procedure used to convert abnormal heart rhythms, such as atrial fibrillation, back to normal sinus rhythm. It involves delivering a synchronized electrical shock to the heart at a specific point in the cardiac cycle to restore normal rhythm.

C. Pericardiocentesis: Pericardiocentesis is a procedure used to remove fluid from the pericardial sac surrounding the heart. It is typically performed to relieve cardiac tamponade or to investigate the cause of pericardial effusion.

D. Pericardial window: A pericardial window is a surgical procedure performed to create a permanent opening in the pericardium, the sac surrounding the heart. It is usually done to drain fluid or air from the pericardial space, often in cases of recurrent pericardial effusion or cardiac tamponade.
