Question 7

nonmelanoma skin cancer maj risk fac

Answer 7

D - Diameter, larger than 6mm

Answer 12

􏱍 Hypothermia
􏱍 Tissue/blood destruction and hemoglobin loss leads hypoxia
􏱍 Glomerular filtration rate and urinary output reduced and metabolic acidosis
􏱍 Plasma loss of proteins 4-6 hours post injury results in reduced intravascular colloid pressure causing plasma fluid loss
