The nurse is preparing to administer an intradermal medication. Which item will form to indicate the medication was injected at the proper depth?
1. Diluent
2. Wheel
3. Wheal
4. Blister
Correct Answer: 3
A wheal, or small raised area, forms when an intradermal medication is injected at the proper depth. A diluent is the solution used to mix powdered medication into an injectable form. Wheel is a misspelling of the word wheal. The wheal resembles a blister, but this would be incorrect terminology.
