Certified Wildlife Rehabilitator Practice Test

Which vitamin should a wildlife rehabilitator be cautious about overdosing?

1. Vitamin A

2. Vitamin C

3. Vitamin D

4. Vitamin K

The correct answer is: Vitamin D

A wildlife rehabilitator should be particularly cautious about overdosing on Vitamin D. This vitamin plays a critical role in calcium metabolism and bone health. While it is essential for many species, excessive amounts can lead to serious health issues, such as hypercalcemia, which can cause kidney damage, cardiovascular problems, and ultimately be fatal. Wildlife often gets Vitamin D from sun exposure and dietary sources, and since different species have varying tolerances and needs for this vitamin, it is crucial to monitor intake closely. Unlike some water-soluble vitamins, which are excreted when in excess, Vitamin D is fat-soluble and can accumulate in fatty tissues, posing increased risks of toxicity. In contrast, other vitamins such as C, K, and A also have their own specific requirements and potential toxicity levels, but the particular concern for a risk of overdose is most pronounced with Vitamin D, making it a key focus for wildlife rehabilitators in their dietary supplementation practices.
