Q

5.08 Semmes-Weinstein filament
35
A fasting value of ___ or a 2 hour value of ____ during oral glucose tolerance test would indicated diabetes mellitus
>125 | > 200
36
nonenzymatic glycosylation of the lens protein is 2x as high in diabetic patients than non-diabetics and causes _____
diabetic cataracts
37
radioactive contrast material should not be given to a patient with serum creatinine

38
lab values of of DKA patient: glucose pH serum bicarb

patient presents with pain and swelling with "rocker bottom" deformity and ulceration → osteoclastic destruction leading to deranged and unstable joints in the midfoot
Charcot foot arthopathy
40
pharmacotherapy that can decrease microalbuminuria
antihypertensive → ACE inhibitors

diabetic ketoacidosis in T2DM is most likely due to
severe stress → sepsis or trauma, broken insulin pump
42

ischemia of LE, ED, intestinal angina
43
three other things associated with hypoglycemic coma
severe insulin deficiency (DKA) mild-moderate insulin deficiency (HHS) lactic acidosis
44
denervation of small muscles of foot → clawing of toes and displacement of submetatarsal fat pads anteriorly leads to ____
