What does the abbreviation 'EN' indicate regarding medication administration?

The abbreviation 'EN' in the context of medication administration typically stands for "enteral," which refers to the route of delivering medication or nutrition through the gastrointestinal (GI) tract. However, in the specific context of your question regarding nasal administration, 'EN' could be interpreted as indicating the use of both nostrils for a substance that is administered nasally.

When a medication is intended for nasal administration, specifying that it is to be used in both nostrils can help ensure that the dose reaches the desired area for effective absorption. This is particularly important for medications that require a specific delivery method for optimal effectiveness.

Understanding the specific context of abbreviations is crucial in ensuring proper medication administration and avoiding potential errors. The other choices, while relevant to different aspects of medication delivery, do not align with the typical meaning of 'EN.' For example, intravenous administration refers to a direct delivery into the bloodstream, which is not indicated by this abbreviation.
