Which of the following is a common sign of nitrogen narcosis?

• A. Impaired judgment
• B. Euphoria
• C. Disorientation
• D. All of the above

Answer: (D)

Nitrogen narcosis, often referred to as "rapture of the deep," occurs when divers descend to depths typically greater than 30 meters (100 feet) while inhaling nitrogen under increased pressure. This condition can lead to a range of symptoms that affect the diver's cognitive and motor functions. Impaired judgment is one of the hallmark signs of nitrogen narcosis; divers may make poor decisions or become overly confident, which can pose significant risks during a dive. Euphoria is also commonly experienced; divers may feel an uncharacteristic sense of well-being or happiness, which can further cloud their judgment and lead to dangerous behaviors. Disorientation can manifest as confusion or difficulty understanding one’s surroundings, making it difficult for divers to orient themselves and assess their situation accurately. Since nitrogen narcosis can produce all these symptoms, recognizing the presence of impaired judgment, euphoria, and disorientation is crucial for divers. Each symptom contributes to the overall risk profile when diving, particularly at deeper depths. Understanding that these signs commonly occur together helps divers and dive supervisors take appropriate precautions and responses to ensure safety in the water.
