Which of the following is a reason drugs are administered to maintain health?

Maintaining health often involves the use of substances that can provide the necessary nutrients to support bodily functions and prevent deficiencies. Vitamins play a crucial role in this process as they are essential organic compounds that the body needs to function properly. They contribute to various biochemical processes, support the immune system, and promote growth and development, making them vital for overall health maintenance.

While vaccinations are an important preventative measure against infectious diseases, they specifically target disease prevention rather than general health maintenance. Aspirin is commonly used for pain relief and anti-inflammation and is not typically classified as a substance primarily to maintain health on its own. Insulin is critical for managing diabetes rather than serving as a broad health maintenance drug. In contrast, vitamins directly support health by providing essential nutrients that the body may lack, making them integral in maintaining health over the long term.
