Which of the following is NOT a Decompression Sickness Type 2 sign?

Explanation:
Decompression sickness signs are split into Type 1 and Type 2, with Type 2 involving more serious, deeper systems like the nervous system, inner ear, and lungs. Loss of consciousness is a clear brain/nerve sign, so it fits Type 2. Hearing loss comes from inner ear involvement, also Type 2. Coughing can occur with lung involvement (pulmonary gas embolism), making it a Type 2 sign as well. Marbling, or skin rash, is a cutaneous/nonspecific skin-joint finding typical of Type 1 DCS and does not indicate deeper involvement. So marbling is not a Type 2 sign.
