Which of the following is NOT a component of a dermatologic examination?

A dermatologic examination focuses specifically on evaluating the skin and its associated structures, such as hair and nails. Key components of this type of examination include observing general skin health (general exam), noting any swelling that may be indicative of inflammatory processes, and examining any lesions present on the skin, which could range from benign to more concerning conditions.

Abdominal auscultation, while a crucial aspect of a comprehensive physical examination in veterinary practice, does not pertain specifically to dermatology. It is primarily used to assess the gastrointestinal system for signs of motility, bowel sounds, and organ health, making it unrelated to the specific components involved in examining the skin and associated structures. Hence, this choice is not part of a dermatologic examination.
