• D. Visual symptoms, Ear symptoms, Nausea, Twitching, Irritability, Dizziness, Seizures

Answer: (A)

VENTIDC is the mnemonic used for decompression illness symptoms, mapping each letter to a specific sign to watch for in divers. V stands for Visual symptoms, E for Ear symptoms, N for Nausea, T for Tremors, I for Irritability, D for Dizziness, and C for Convulsions. Tremors is the term traditionally used for the motor disturbances in this list, not Twitching, and Convulsions is the preferred term over Seizures. The phrasing uses Visual symptoms rather than Vision symptoms to match the standard wording. So the expansion is Visual symptoms, Ear symptoms, Nausea, Tremors, Irritability, Dizziness, Convulsions.
