What are the methods of intake considered in medical terms?

In medical terms, the methods of intake refer to the various ways substances, particularly medications, can enter the body. The option that includes by mouth, IV (intravenous), and NG (nasogastric) accurately represents three primary routes of administration that healthcare professionals frequently employ.

By mouth is a common route, allowing medications to be absorbed through the digestive system. Intravenous administration delivers substances directly into the bloodstream, which allows for rapid effects. The nasogastric route is utilized for patients who may be unable to take medications orally, using a tube that goes through the nose to the stomach for both medication and nutritional intake.

The other options, while they do provide methods of administration, do not comprehensively cover the primary intake routes as effectively as the selected answer. Injections can be major methods, yet they are more specific forms of administration rather than broad categories. Thus, the correct answer underscores the importance of understanding the primary and commonly utilized methods for medication intake in clinical practice.
