Post-exposure medical care should be sought within how many hours after a needle-stick exposure?

• A. Within 2 hours of exposure.
• B. Within 24 hours.
• C. Within 1 week.
• D. Immediately after exposure.

Answer: (B)

Prompt post-exposure evaluation is crucial after a needle-stick because early risk assessment and starting preventive therapy can significantly reduce the chance of infection. Seeking medical care within 24 hours gives clinicians time to determine the level of exposure risk, update or give necessary vaccines, and begin post-exposure prophylaxis if indicated. The sooner this process starts, the more effective the preventive measures tend to be, since antiviral prophylaxis is most beneficial when begun promptly and before the virus has a chance to establish infection. While earlier care is ideal, a 24-hour window is the commonly taught target that balances urgency with practical access to medical services. If more time has passed, you should still seek care promptly, as management and testing can still guide decisions and help reduce risk.
