Which term describes injecting directly into a vein?

• A. Intravenous administration
• B. Intramuscular administration
• C. Subcutaneous administration
• D. Oral administration

Answer: (A)

Injecting directly into a vein is intravenous administration. This route delivers medication straight into the bloodstream, giving the fastest onset and the most precise control of dose, which is why it’s used when a rapid effect is needed or exact dosing is crucial. Intramuscular administration places the drug into muscle tissue, where absorption is slower, while subcutaneous administration goes into the fatty tissue beneath the skin and also absorbs more slowly. Oral administration involves swallowing the drug to be absorbed through the digestive system and liver before reaching systemic circulation. IV delivery can be given as a quick bolus or as an infusion for steady delivery, but it requires sterile technique and carries risks such as infiltration, phlebitis, or air embolism.
