Wound Treatment Associate (WTA) Practice Exam

When is it appropriate for a patient to take zinc supplementation?

1. As a standard preventive measure

2. When evidence of zinc deficiency is present

3. Only when wounds are healing

4. After taking Vitamin A

The correct answer is: When evidence of zinc deficiency is present

Zinc supplementation is most appropriate when evidence of zinc deficiency is present. Zinc plays an essential role in numerous bodily functions, including immune response, wound healing, and protein synthesis. Deficiency can lead to symptoms such as impaired immune function, delayed wound healing, and skin lesions. When assessing a patient, it's crucial to check their zinc levels through dietary intake histories or lab tests, as the need for supplementation should be based on a recognized deficiency rather than a standard preventive approach, as not everyone requires additional zinc. While zinc can support the healing of wounds, supplementation solely based on wound healing without confirmed deficiency may lead to unnecessary intake. Additionally, timing relative to Vitamin A intake is not a determining factor for zinc supplementation; rather, it concerns the individual's nutritional status and specific clinical indications for zinc usage. Thus, initiating zinc supplementation should always lean on the findings of a deficiency.
