A nurse is reinforcing teaching to a group of nursing students about possible psychosocial changes a client might have after sustaining a neurologic injury such as increased intracranial pressure. Which of the following psychosocial changes should the nurse include in the teaching?

A. The aortic and mitral valves are the most commonly replaced valves: This statement is accurate. The aortic and mitral valves are indeed the most commonly replaced valves in cardiac valve replacement surgeries. Aortic valve replacement is commonly performed for conditions such as aortic stenosis or regurgitation, while mitral valve replacement is often indicated for mitral regurgitation or stenosis.

B. Mitral valve insufficiency occurs during the diastolic phase of the cardiac cycle: This statement is incorrect. Mitral valve insufficiency, also known as mitral regurgitation, occurs during the systolic phase of the cardiac cycle. It involves the backflow of blood from the left ventricle into the left atrium during ventricular systole, leading to volume overload of the left atrium and potentially causing symptoms such as dyspnea and fatigue.

C. Inadequate closure of the tricuspid valve causes overload in the left ventricle: This statement is incorrect. Inadequate closure of the tricuspid valve leads to regurgitation of blood from the right ventricle back into the right atrium during ventricular systole. This condition, known as tricuspid regurgitation, causes volume overload in the right atrium and ventricle, rather than overload in the left ventricle.

D. Aortic stenosis increases right ventricular systolic pressure and decreases afterload: This statement is partially correct. Aortic stenosis indeed increases left ventricular systolic pressure and decreases afterload, not right ventricular pressure. The increased afterload on the left ventricle can lead to left ventricular hypertrophy and eventually heart failure. However, aortic stenosis does not directly affect right ventricular systolic pressure.

A. Limit exercise to 10 min, 2 days per week. This recommendation is incorrect. Regular physical activity is essential for heart health. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week, spread throughout the week.

B. Monitor blood pressure This recommendation is correct. Monitoring blood pressure is an essential aspect of heart disease prevention. High blood pressure (hypertension) is a significant risk factor for heart disease, so regular monitoring allows for early detection and management.

C. Lose weight if necessary. This recommendation is correct. Maintaining a healthy weight or losing weight if overweight or obese is important for heart disease prevention. Excess weight, especially around the abdomen, increases the risk of heart disease and other health conditions.

D. Eat a diet high in saturated fats. This recommendation is incorrect. A diet high in saturated fats is associated with an increased risk of heart disease. Instead, the nurse should encourage a heart-healthy diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats.

E. Maintain current cholesterol level This recommendation is not entirely accurate. While maintaining healthy cholesterol levels is important for heart health, individuals with high cholesterol levels may need to take steps to lower their cholesterol through lifestyle modifications and, in some cases, medication. Therefore, simply maintaining current cholesterol levels may not be sufficient for heart disease prevention.
