BIOS 251 EXAM 3 STUDY GUIDE QUESTIONS
AND ANSWERS
◉ What is the purpose of infection control in burn treatment?
Answer: To prevent burns from becoming infected.
◉ What is debridement in the context of burn treatment? Answer:
The removal of eschar (burned or dead tissue).
◉ What is the most common type of skin cancer? Answer: Basal cell
carcinoma.
◉ Describe the appearance of basal cell carcinoma. Answer: It
appears as a shiny, small bump that often enlarges with a 'pearly'
edge and seldom metastasizes.
◉ From which cells does basal cell carcinoma originate? Answer: It
originates from the cells in the stratum basale.
◉ What is squamous cell carcinoma and its potential risk? Answer:

◉ What does the ABCD rule stand for in melanoma detection?
Answer: A for asymmetry, B for border irregularity, C for color, D for
diameter (greater than 6 mm).
◉ What are the six major functions of the skeletal system? Answer:
Blood formation, support, protection, movement, storage and
release of minerals, and storage of triglycerides.
◉ Where is blood formed in the skeletal system? Answer: In red
bone marrow found in the epiphysis of long bones, bones of the axial
