Before a myelogram, which instruction demonstrates understanding of pre-procedure preparation?

• A. I should not eat or drink anything for 8 hours before the procedure
• B. I can have a light breakfast on the day of the procedure
• C. I should stop all medications for 24 hours
• D. I should drink only water during the fast

Answer: (A)

Fasting to reduce the risk of aspiration during anesthesia or sedation is the key idea. For procedures like a myelogram that may use sedation or spinal anesthesia, keeping the stomach empty lowers the chance of vomiting and inhalation of stomach contents if airway protective reflexes are depressed. Eight hours of nothing by mouth is a common, practical safety standard, which is why the instruction stating not to eat or drink anything for eight hours best demonstrates understanding. Rest of the options don’t align with this safety principle: having a light breakfast would break the fast and increase aspiration risk; stopping all medications for 24 hours isn’t a standard, universal preop requirement and could be unsafe without clinician guidance; drinking only water during the fast still counts as intake and would violate the NPO guideline.
