Final answer:
Option D. Advanced age is the factor that does not promote healing, as it is often associated with a slower recovery process due to reduced skin elasticity and a slower rate of cell division.
Step-by-step explanation:
The factors that promote healing include good nutrition, a clean and undisturbed wound, effective circulation, and adequate hemoglobin levels. However, advanced age is not a factor that promotes healing. In fact, older individuals may experience slower healing due to various factors such as reduced cell turnover and decreased production of growth factors.
The student's question pertains to the factors that promote healing with one exception. To address this question, we need to identify which factor does not promote healing. Good nutrition (specifically, adequate intake of proteins and vitamins A and C), a clean, undisturbed wound, effective circulation, and adequate hemoglobin levels all facilitate the healing process. In contrast, advanced age is generally associated with a slower healing process. As people age, their skin and bones may take longer to recover from injuries due to factors such as reduced skin elasticity, a slower rate of cell division, and potential complications from pre-existing conditions.
