Answer 16

MM, eyes, skin turgor

geriatric (old), cachectic (weak/chronically ill) animals

Lift upper lift and press on buccal MM and count how long it takes for pink color to return; check color of MM; feel if MM are moist, dry, or tacky; CRT (capillary refill time) is normal if <2 seconds

Question 28

What are the 8 organs palpated in the abdominal region during a physical examination and what should you be looking out for in each organ?

Answer 28

Liver: (difficult to palpate normally) smooth, well-defined caudal edges; if enlarged in extends beyond the costal arch and has rounded edges; lateral recumbency or standing may help Stomach: (normally not palpated) doughy or fluid-filled (left side) after eating Spleen: (not always palpatable) in the mid abdomen; palpate for irregularity or masses Intestines: not thickness, fluid, gas foreign bodies, or masses; colon is dorsal-caudal (feces vs. mass where feces will be squishy) Kidneys: dorsal-abdominal region in cats and difficult to feel in dogs unless young and thin; compare size, shape, firmness, and irregularities Urinary Bladder: ventral-caudal abdomen; assess size, thickness, calculi, obstruction Uterus: (not normally palpated) tubular shape; look for enlargement due to pyometra (an accumulation of pus in the uterus) or late pregnancy Prostate: only intact males; usually palpated in caudal abdomen ventral to the colon and caudal to the urinary bladder
