Which term describes a physiological condition caused by increased partial pressure of nitrogen, leading to narcotic-like symptoms?

• A. Agonist
• B. Malloy-Weiss syndrome
• C. Nitrogen Narcosis
• D. Ectopic Pregnancy

Answer: (C)

Nitrogen narcosis describes the narcotic-like impairment that arises when the partial pressure of nitrogen in the body becomes elevated, such as when diving deeper underwater while breathing air. As depth increases, more nitrogen dissolves into body tissues and affects nerve function, producing symptoms that resemble intoxication: slowed thinking, poor judgment, dizziness, euphoria, and impaired coordination. The effect is reversible with ascent, as the nitrogen partial pressure decreases and off-gassing occurs. This is the best answer because it directly names the condition caused by increased nitrogen tension and its narcotic-like effects. The other terms describe unrelated concepts: an agonist is a molecule that activates a receptor, Mallory-Weiss syndrome is a tear in the esophagus or stomach lining from vomiting, and an ectopic pregnancy is a pregnancy implanted outside the uterus.
