After teaching a group of students about the different routes of medication administration, the nursing instructor determines that the teaching was successful when the students identify which of the following as a topical drug?
- A. Capsule
- B. Suppository
- C. Nebulized bronchodilator
- D. Nicotine patch
Correct Answer: B
Rationale: Topical drugs are drugs that are applied to the outer layer of the skin but not absorbed through the skin, such as eyedrops and suppositories. A nebulized bronchodilator is an inhaled medication. A nicotine patch delivers the medication transdermally; that is, it is readily absorbed from the skin. A capsule is a form of oral medication.
