Immediate use preparations must be administered within

• A. 30 minutes
• B. 1 hour
• C. 2 hours
• D. 4 hours

Answer: (B)

Immediate-use sterile preparations are for urgent therapy and are prepared outside a full aseptic environment. Because they’re made under less stringent sterile conditions, they carry a higher risk of contamination and instability, so they must be used quickly. The safety standard requires administration within one hour of the start of preparation. If the product isn’t given within that hour, it should be discarded to protect the patient from infection or harm. This time frame is why the correct answer is one hour. Options shorter than one hour are not the rule, and longer windows increase risk, which is why they aren’t appropriate for immediate-use preparations.
