Route of Administration (Part 3)

Drug administration routes are typically designated by the site of application, such as oral or intravenous. Routes of administration are determined not only by ease but also by the drug’s properties and pharmacokinetics.

By taking this quiz, you will gain knowledge about the different routes of drug administration and their applications.

  • Question of

    Administration to the rectum.

    • Rectal
    • Buccal
    • Extra-amniotic
    • Sublingual

    Correct Wrong

    During rectal administration, medications and other fluids are administered via the rectum, which is absorbed through the rectum's blood vessels. For patients with digestive tract motility problems, including dysphagia, the rectal route is useful.

  • Question of

    Administration to the outside of the membrane surrounding a fetus.

    • Extra-amniotic
    • Intradermal
    • Epicutaneous
    • Intraosseous infusion

    Correct Wrong

    In pregnancy, extra-amniotic medication is administered between the fetal membranes and the endometrium of the uterus. For example, it can be used to administer drugs that affect uterine motility, such as oxytocin and prostaglandins, e.g. during labor induction or medical abortion.

  • Question of

    Administration injected into the epidural space around the spinal cord.

    • Epidural
    • Subcutaneous
    • Transdermal
    • Enteral

    Correct Wrong

    In an epidural injection, the medication is injected into the epidural space around the spinal cord. An epidural injection is used to administer local anesthetic agents, analgesics, radiocontrast agents, as well as other medications such as glucocorticoids.

  • Question of

    The administration beneath the tongue.

    • Sublingual
    • Intrathecal
    • Intracavernous
    • Epicutaneous

    Correct Wrong

    The drug is administered sublingually by placing it beneath the tongue. Under the tongue, the mucosa is highly permeable and enables access to the extensive capillary network beneath, resulting in rapid drug absorption.

  • Question of

    Administration to the systemic circulation via dermal diffusion.

    • Transdermal
    • Transmucosal
    • Sublingual
    • Epidural

    Correct Wrong

    Transdermal administration delivers active ingredients across the skin in order to distribute them systemically. Drugs are administered via patches or ointments that are absorbed from the skin into the bloodstream for systemic effect.

  • Question of

    Administration to the respiratory tract by inhaling orally or nasally.

    • Inhalation
    • Transdermal
    • Transmucosal
    • Topical

    Correct Wrong

    Oral or nasal inhalation is a route of administration within the respiratory tract for local or systemic effects.

  • Question of

    The administration is placed between the lip and the gingiva (gum).

    • Sublabial
    • Parenteral
    • Intravitreal
    • Intrathecal

    Correct Wrong

    A sublabial administration involves placing an active substance or medication between the lip and the gingiva (gum).

  • Question of

    Administration in the layer below the dermis and epidermis of the skin.

    • Subcutaneous
    • Intracardiac
    • Intramuscular
    • Intradermal

    Correct Wrong

    Subcutaneous injections are administered under the dermis and epidermis of the skin. The use of subcutaneous injections is highly effective for administering medications such as insulin, morphine, diacetylmorphine, and goserelin.

  • Question of

    An application of a drug directly onto the skin surface.

    • Epicutaneous
    • Otic
    • Extra-amniotic
    • Sublabial

    Correct Wrong

    Epicutaneous (application onto the skin). It can be used for local effects, such as allergy testing or typical local anesthesia. In addition, it can be used for systemic results when the active substance diffuses through the skin through transdermal administration.

  • Question of

    An administration in which the substance is applied directly to the vaginal area.

    • Intravaginal
    • Extra-amniotic
    • Epicutaneous
    • Intralesional

    Correct Wrong

    The intravaginal route involves applying the substance inside the vagina. Most commonly delivered are estrogens, progestogens, antibacterials, and antifungals to treat bacterial vaginosis and yeast infections.

  • Question of

    The administration of substance or medicine into or within a vein or veins.

    • Intravenous
    • Ophthalmic
    • Intralesional
    • Transmucosal

    Correct Wrong

    In intravenous therapy, fluids, medications, and nutrients are administered directly into a person's veins. Most commonly, intravenous administration is used to rehydrate or to provide nourishment to those who cannot swallow food or liquids.
