Certified Wound Ostomy Nurse (CWON) Practice Test

Which nutritional factors are crucial for optimizing wound healing?

1. Sugar, fats, and processed foods

2. Protein, vitamins, and minerals

3. Caffeine, processed carbohydrates, and fiber

4. Only protein and water

The correct answer is: Protein, vitamins, and minerals

Nutrition plays a vital role in the wound healing process, as the body requires specific nutrients to repair tissue and support immune function. The correct answer emphasizes the importance of protein, vitamins, and minerals, which are essential components of a well-balanced diet for wound healing. Protein is critical because it provides the amino acids necessary for tissue repair, collagen synthesis, and the formation of new cells. Adequate protein intake helps to maintain muscle mass and supports the overall healing process, especially in individuals with pressure ulcers or surgical wounds. Vitamins play a crucial role as well. For instance, vitamin C is important for collagen production and immune function, while vitamin A supports skin health and epithelial growth. B vitamins are involved in energy metabolism and red blood cell production, both important for healing. Minerals, such as zinc, are essential for cellular metabolism and immune response. Zinc deficiency can lead to delayed wound healing and increased susceptibility to infections. Iron is also important for oxygen transport in the blood, promoting healing by ensuring that tissues receive the necessary oxygen and nutrients. The other choices do not accurately reflect the nutritional requirements for optimal wound healing, as they include either harmful components or are incomplete in their recommendations. For example, sugar and processed foods can lead to inflammation and negatively
