Physiological AdaptationQuestion 181 of 2368
The nurse is teaching about vitamin supplements. Why can overconsumption of vitamins A and D cause toxicity?
- They are made by the body and then excessively stored in muscle
- They are water soluble and build up in the blood over time
- They are stored in fat tissue and the liver and are not easily excreted
- They are rapidly excreted and damage the kidneys on the way out
Show answer
Correct answer: They are stored in fat tissue and the liver and are not easily excreted
Fat-soluble vitamins are stored in fatty tissue and the liver, so the kidneys do not excrete them easily and they can build up.
