Flashcards in Chapter 63 Malnutrition and Obesity Deck (26):
1

Drugs to stimulate appetite

Periactin, Megace

2

Overweight

10% over ideal body weight

3

Obesity

20% over ideal body mass

4

Morbid obesity

100% above ideal body weight

5

Drugs for obesity

Meridia, Tenuate, Bontril, Xenical

6

Hospital nutritional screening

height and weight, weight history, eating habits, ability to chew and swallow, and any recent changes in appetite or food intake

7

Marasmus

calorie malnutrition where body fat and protein are wasted but serum proteins are often preserved

8

Kwashiorkor

lack of protein quantity and quality in the presence of adequate calories. Body weight is more normal and serum proteins are low

9

Marasmic-kwashiorkor

combined protein and energy malnutrition. Often presents clinically when metabolic stress is imposed on a chronically starved patient

10

Where is protein synthesized?

the liver

11

malabsorption

occurs with malnutrition due to atrophy of gastric mucosa and loss of intestinal villi

12

H&H with malnutrition

May be low due to low albumin, anemia, infection, catabolism, or chronic disease
High values could indicate dehydration or hemoconcentration

13

Serum albumin

reflects nutritional status a few weeks before testing and is not the most sensitive study (should be 3.5-5.0)

14

Prealbumin

more sensitive indicator of protein deficiency because it has a short half life of 2 days. (normal is 15-36)

15

Transferrin

an iron transport protein with a short half life of 8-10 days which is also a sensitive indicator of protein status

16

Cholesterol levels

typically low with malabsorption, liver disease, pernicious anemia, end stage cancer, and sepsis (below 160 indicates malnutrition)

17

Total lymphocyte count and malnutrition

malnutrition suppresses the immune system so this level is usually decreased below 1500

18

Cyproheptadine (periactin)

an antihistamine to stimulate appetitie

19

Refeeding syndrome

complication of enteral feeding
life threatening condition brought on when nutrition is restarted for someone in a starvation state
insulin production resumes and the cells take up glucose and electrolytes from the bloodstream thus depleting serum levels

20

Refeeding syndrome sx

cardiovascular, respiratory, and neurological problems primarily caused by hypophosphatemia. Shallow respirations, weakness, acute confusion, seizures, and increased bleeding.

21

Gastric pH

0-4
6 or more indicates the feeding tube is probably in the lungs

22

Fat overload syndrome

Can occur with administration of Partial parenteral nutrition
Sx: fever, increased triglycerides, clotting issues, and multisystem organ failure

23

Drugs that can cause weight gain with long term use

Corticosteroids, estrogens, NSAIDS, antihypertensives, antidepressants, antiepileptic, oral antibiotics, psychoactive drugs

24

Post-op complications for gastric surgery

Anastomotic leaks are the most common serious complication and cause of death after gastric bypass surgery
Dumping syndrome

25

Sx of Anastomotic leaks

increasing back, shoulder, or abdominal pain, restlessness, and unexplained tachycardia and oliguria

26

Dumping syndrome sx

tachycardia, nausea, diarrhea, abdominal cramping
