What is the primary symptom of nitrogen narcosis experienced by divers?

Euphoria similar to alcohol intoxication
Sudden vision improvement
Immediate muscle relaxation
Decreased heart rate

The correct answer is: Euphoria similar to alcohol intoxication

Nitrogen narcosis is a condition that affects divers when they descend too deeply into the water. It is caused by the increased pressure of the gases in the body, primarily nitrogen, and can cause symptoms similar to being drunk. This is why the primary symptom of nitrogen narcosis is euphoria similar to alcohol intoxication, as stated in option A. Option B, sudden vision improvement, is an incorrect choice because nitrogen narcosis can actually cause blurred vision and difficulty focusing. Option C, immediate muscle relaxation, is also incorrect because nitrogen narcosis can lead to loss of coordination and difficulty moving. Option D, decreased heart rate, is incorrect because divers experiencing nitrogen narcosis may actually have an increased heart rate due to the physiological effects of the condition.
