Glass bottles used for certain IV solutions must be what before administration?

• A. Vented
• B. Heated
• C. Left at room temperature
• D. Light-protected

Answer: (A)

When using glass IV bottles, air must be able to enter as fluid is withdrawn. If the bottle isn’t vented, a vacuum can form inside as volume decreases, which resists further flow or stops it altogether. A vented closure or vented stopper allows air to re-enter the bottle while keeping the solution uncontaminated, ensuring a smooth, continuous flow into the IV line. Heating, room-temperature storage, or light-protection aren’t the actions required to prepare the bottle for administration in this context.
