Which of the following methods transmits a drug directly into the bloodstream? A ingestion
B. inhalation
C. direct contact
D. intravenous

The answer is D

The method that can make a drug go directly into the bloodstream is intravenous (option D).

Explanation:

The intravenous pathway consists of introducing a catheter into a vein with the objective of administering drugs that go directly into the bloodstream. This is to ensure that a medication takes effect more quickly.

The term parenteral pathway is used to identify the administration of medications intramuscularly, subcutaneously and endovenously, since they do not use the digestive system for medication.

Methods that include parenteral administration of medications have a faster effect, but must be performed by qualified health personnel.

The other options are not correct because:

    A. Ingestion is related to enteral or oral administration.

    B. Inhalation is intended for drugs whose effect is mainly in the respiratory tract.

    C. Direct contact is used with certain preparations in creams and oils, intended for the treatment of skin diseases.
