Question: 1 / 975

Which of the following is NOT a key characteristic of nitrogen narcosis?

Euphoria

Confusion

Increased alertness

The characteristic of increased alertness is not associated with nitrogen narcosis. Nitrogen narcosis is a condition that occurs in divers when they breathe nitrogen at high pressures, leading to various effects on cognitive functioning and motor skills. Key symptoms include euphoria, confusion, and a slowed motor response, which reflect the impairment of mental processes and physical coordination.

Euphoria can create a false sense of well-being, while confusion can make it difficult for individuals to think clearly or process information effectively. Additionally, a slow motor response can hinder their ability to react to situations quickly and safely. In contrast, increased alertness implies heightened awareness and mental acuity, which contradicts the impairing effects that nitrogen narcosis has on a diver’s cognitive and physical abilities.
