Question

Which of the following nutritional deficiencies may delay wound healing?

1) Vitamin C deficiency
2) Iron deficiency
3) Protein deficiency
4) All of the above

Answer 1

Nutritional deficiencies in Vitamin C, Iron, and Protein can all delay wound healing, as they play crucial roles in collagen formation, oxygen transport, tissue repair, and the immune response.

Step-by-step explanation:

Nutritional deficiencies can have a significant impact on wound healing. A deficiency in Vitamin C can result in scurvy, which impairs the formation of collagen, an essential component required for healing wounds.

This leads to fragile capillaries, swollen gums, and weak bones that may fracture easily.

Similarly, an Iron deficiency affects the body's ability to transport oxygen in the blood, crucial for tissue repair and regeneration. Protein deficiency can weaken the immune response and reduce the production of collagen, which is vital for tissue repair. Therefore, the correct answer to which nutritional deficiencies may delay wound healing is option 4) All of the above.
