🔍 Key Concepts
• Medical emergency codes (MN series) used in maritime radiotelegraphy/communication for specific injuries or conditions
• How symptom-based codes are grouped (e.g., head, eyes, limbs, burns, poisoning)
• Difference between codes for loss of sight, eye injuries, and neurological issues
💭 Think About
• Look for which group of codes would logically cover sudden blindness in both eyes rather than a minor eye irritation or local injury
• Think about whether this situation is more like a trauma to the eyes, a gradual vision problem, or an acute, serious loss of function
• Consider what type of condition would typically require urgent medical advice from a radio medical service and how those are encoded
✅ Before You Answer
• Verify which option corresponds specifically to sudden loss of vision in both eyes, not just general eye pain or redness
• Check that the chosen code is not for a single-eye injury only
• Confirm that the description of the code implies a serious, acute condition, appropriate for an emergency medical message
