Adult-Gerontology Clinical Nurse Specialist (CNS) Practice Exam

Which of the following is recommended by a clinical nurse specialist to maintain a healthy immune system in aging patients?

1. Maintaining close social interactions

2. Eating large, sugary meals

3. Vaccinations

4. Exercising in very cold weather

The correct answer is: Vaccinations

Vaccinations are a fundamental component in maintaining a healthy immune system, especially in aging patients. As individuals age, their immune response tends to decline, making them more susceptible to infections and illnesses. Vaccinations help bolster the immune system by preparing it to defend against specific pathogens. They not only provide direct protection against diseases such as influenza and pneumonia, which are more severe in older adults, but they also contribute to the overall public health by reducing the spread of contagious diseases. Effective vaccination not only protects the elderly individual but also helps create a herd immunity that benefits the community at large. Therefore, regular updates and appropriate vaccines are highly recommended for aging patients as they play a crucial role in preventing illness and supporting immune system health. Other options may not foster immune health effectively. For instance, maintaining close social interactions can offer emotional support and alleviate feelings of loneliness, which may indirectly benefit health, yet it does not directly enhance immune function. Meanwhile, consuming large, sugary meals can lead to various health issues, including obesity and diabetes, which can negatively impact immune health. Exercising in very cold weather can pose risks such as hypothermia and does not specifically support immune health; rather, exercise should be appropriately moderated to prevent any adverse effects, particularly in older adults
