For stage 3 or 4 pressure ulcers, which supplementation is recommended?

• A. Arginine, micronutrients, and high protein supplements
• B. Vitamin A only
• C. No supplementation
• D. Extra calcium only

Answer: (A)

Healing advanced pressure ulcers hinges on sufficient calories and protein plus nutrients that support collagen formation and immune function. Arginine acts as a helpful aid in wound repair by supporting collagen deposition and immune cell activity, while micronutrients such as zinc and vitamin C are essential cofactors for collagen synthesis and healing processes. Providing high-protein supplements helps ensure an adequate nitrogen supply for tissue repair, which is especially important when intake is limited or the healing demand is high. Together, this approach covers both the building blocks and the supporting nutrients the body needs to regenerate tissue in stage 3 or 4 ulcers. Relying on vitamin A alone doesn’t meet the full needs for protein and ongoing wound repair, and extra calcium alone isn’t a driver of healing; not supplementing at all leaves important nutrients short, slowing recovery.
