The act of rubbing an oil into the skin to produce a local effect is known as

Appeared in: Chitranjjan National Cancer Institute Kolkata - 2021

Explanation

Inunction is the specific term for the act of rubbing a medication, such as an oil or ointment, into the skin.
The goal of inunction is typically for the medication to be absorbed through the skin and produce a local effect at the site of application.
This method is distinct from other forms of topical application that may not require rubbing, such as applying a lotion or a transdermal patch.

Option A: Injection involves piercing the skin with a needle to deliver medication into a muscle, vein, or subcutaneous tissue, not rubbing it on the surface.
Option B: Inhalation involves breathing a medication into the lungs. It does not involve application to the skin.
Option D: Infusion is the process of administering fluids or medications directly into the bloodstream over a prolonged period, typically through an intravenous (IV) line.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Routes of Medication Administration as background academic context rather than a clinical decision trigger.
Nurses must use the correct technique for each medication route to ensure effectiveness and patient safety. For inunction, this includes wearing gloves to prevent self-absorption of the drug.
Patient education is crucial. A nurse must teach the patient how to properly apply topical medications, including the amount to use, the frequency, and the importance of rubbing it in gently but thoroughly.
What if the medication was a transdermal patch instead of an oil? The route would still be topical, but the specific action would not be inunction. The nurse would instruct the patient to apply the patch to clean, dry skin and hold it in place, not rub it.

How to Approach the Question

First, identify the key actions and substances described in the question stem: 'rubbing', 'oil', 'into the skin'.
Analyze the core concept being asked. The question is asking for the specific term for this action.
Evaluate each option based on its definition in pharmacology.
Option A (Injection) involves a needle. This doesn't match 'rubbing'.
Option B (Inhalation) involves breathing. This doesn't match 'rubbing on skin'.
Option C (Inunction) is defined as rubbing a substance into the skin. This perfectly matches the question.
