The lymphatic system. The respiratory system. The gastrointestinal tract. The subcutaneous tissue. 2 What is the primary function of the transdermal route of administration (e.g., patches)? * To bypass the acidic environment of the stomach entirely. To ensure 100% bioavailability of the drug. To achieve immediate, high peak plasma concentrations. To deliver a drug locally to the skin surface for dermatological issues. To provide slow, controlled systemic delivery over an extended period. 3 What is the main clinical advantage of using the rectal route (PR) for drug administration? * It provides the fastest absorption rate among all non-parenteral routes. It allows for precise titration of dosage. It is mandatory for highly lipid-soluble drugs. It ensures complete avoidance of the hepatic portal system. It is the preferred route for unconscious or vomiting patients. 4 What is the primary disadvantage associated with the oral (PO) route of drug administration? * Unpredictable absorption due to first-pass hepatic metabolism and gastric acid degradation. High cost of formulation. Necessity of sterile equipment. Risk of immediate allergic reaction. Pain and tissue damage at the injection site. 5 Which route of administration is typically used for local effect in the respiratory tract, such as for asthma inhalers? * Transdermal Intrathecal Subcutaneous (SC) Intradermal (ID) Inhalation 6 Administration into the cerebrospinal fluid (CSF) is achieved via which specialized route? * Intra-arterial Intra-articular Intraosseous Intrathecal Epidural 7 Drugs administered via the intramuscular (IM) route are absorbed from the muscle tissue into the bloodstream. This route is generally preferred over subcutaneous injection for administering what type of solution? * Highly irritating or viscous solutions. Very small volumes (less than 0.5 mL). Drugs intended for slow, sustained release over several days. Drugs requiring extremely rapid absorption (faster than IV). Drugs that are highly sensitive to pH changes. 8 A drug administered via the sublingual route is intended to be absorbed primarily through which mechanism? * Absorption via the lymphatic system in the muscle tissue. Absorption directly into the portal circulation. Absorption via the lungs\\\\\\\\\\\\\\\' alveoli. Absorption across the highly vascular mucous membranes under the tongue. Absorption through the thick stratum corneum of the skin. 9 Which route of drug administration offers the fastest onset of action, bypassing the first-pass metabolism entirely? * Intravenous (IV) Rectal (PR) Intramuscular (IM) Oral (PO) Sublingual (SL) 10 Which statement accurately describes the bioavailability of a drug administered intravenously (IV)? * Bioavailability is often lower than the intramuscular route. Bioavailability is dependent on gastric emptying time. Bioavailability is generally considered 100%. Bioavailability is comparable to the oral route. Bioavailability is always less than 50%. ← Previous Next → Submit Quiz ✓
