How may topical medications be administered?

  1. Direct application

  2. Injection

  3. Phonophoresis

  4. A and B

The correct answer is: A and B

Topical medications can be applied directly to the skin or injected directly into the body. Phonophoresis, the use of ultrasound to help topical medications penetrate the skin, is also a method of administration for topical medications, but is not the only way. D is the correct answer because it encompasses both methods of application for topical medications. While A and C may seem like viable options, option B is incorrect because injections are not a form of topical administration, rather they are considered systemic administration. It is important to understand the different methods of medication administration in order to ensure the most effective and appropriate treatment for a patient.
