Which type of medication administration involves the use of drops or ointments?

The correct choice highlights a method of medication administration where the drug is delivered directly into a specific area, often involving the use of drops or ointments. Instillation specifically refers to the process of applying a liquid medication in drops, typically into the eyes, ears, or nose. This method ensures that the medication is effectively targeted to the intended site, providing localized treatment. For example, eye drops are instilled directly onto the surface of the eye, and ear drops are placed into the ear canal.

While topical medications are also applied to the skin, they may come in various forms such as creams, gels, or lotions but do not specifically refer to the drop method. Inhalation involves delivering medication through the respiratory system, often using inhalers or nebulizers, which differs from the droplet application seen in instillation. Transdermal medications are absorbed through the skin via patches or gels, providing systemic effects rather than localized treatment via drops or ointments. Thus, instillation is the most accurate term for the context of administering medication in drop or ointment form.
