Q

radiograph vs CT

A

radiograps have a fixed xray tube and one beam going through pt

CT: xray tube moves around patient and receptors measure remanent radiation

18
Q

Tx for obesity major components

A
  1. assist w lifestyle modifications (PA and diet)
  2. nutritional programming
  3. exercise programming
19
Q

to change weight by 1 pound, caloric intake must be decreased or increased by ______ calories

A

3,500

20
Q

PA for modest and greatest weight loss

A

> 150 min for moderate
225-400 for greatest weight loss

21
Q

exercise, diet, or a combo gives the most weight loss over two years?

A

exercise alone lost the most followed by exercise with diet

22
Q

Exercise guidelines for weightloss

A

5-7d/wk
250-300min moderate intensity exercise

23
Q

surgical options are only appropriate for those with BMI of ________

A

> 40 or >35 with comorbidities

24
Q

increased adipose puts the patient in a chronic __________state

A

proinflammatory

25
Q

what diseases is chronic inflammation linked to

A

CVD

ARTHRITIS

CANCER

26
Q

Central abdominal obesity. M vs W

A

M: apple android

W: pead gynoid

27
Q

T or F: obesity cluster –> metabolic syndrome –> type II DM

A

true

just know this, idk what to tell you… metabolic syndrome is the precursor to DM

28
Q

wait circumference values for metabolic syndrome

A

Men >40
W >35

29
Q

triglyceride levels for metabolic syndrome

A

> 150

30
Q

HDL values for Metabolic syndrome

A

<40 M
<50 W

31
Q

Type 1 diabetes

A

lack of insulin secretion = glucose accumulation from liver

autoimmune destruction of beta cells in pancreas

ketone bodies form and accumulate = DANGER

32
Q

Type 2 diabetes

A

slow onset of insulin resistence then insulin deficiency with progressive decline in beta cell function

associated w obesity

33
Q

whats more dangerous? hypoglycemia or hyperglycemia? and what are their values

A

HYPOGLYCEMIA = blood glucose <70 = more dangerous

hyperglycemia = bg >300

34
Q

cardiopulm complications of diabetes

A

htn, cva, node dysfunction, chf, pad

thickening of alveolar endothelial and capillary basal laminae

endothelial dysfunction

35
Q

kidney function

A

regulate serum osmolality , acid base balance

36
Q

cardiovascular complications of chronic kidney disease

A
  • increase risk of CV events
  • HTN
  • Accelerated atherosclerosis
  • HF
  • abnormal LV structure
37
Q

pulmonary complications of chronic kidney disease

A
  • PULMONARY EDEMA
  • fibrinous pleuritis and pulm calcification
  • decrease in arterial PaO2
38
Q

what type of exercise for patients with chronic kidney disease and failure?

A

resistance training combined with aerobic exercise

39
Q

Clinical implications/things to look for for physical therapy for pts with CKD and CKF

A
