Chapter 63 Malnutrition and Obesity Flashcards
Drugs to stimulate appetite
Periactin, Megace
Overweight
10% over ideal body weight
Obesity
20% over ideal body mass
Morbid obesity
100% above ideal body weight
Drugs for obesity
Meridia, Tenuate, Bontril, Xenical
Hospital nutritional screening
height and weight, weight history, eating habits, ability to chew and swallow, and any recent changes in appetite or food intake
Marasmus
calorie malnutrition where body fat and protein are wasted but serum proteins are often preserved
Kwashiorkor
lack of protein quantity and quality in the presence of adequate calories. Body weight is more normal and serum proteins are low
Marasmic-kwashiorkor
combined protein and energy malnutrition. Often presents clinically when metabolic stress is imposed on a chronically starved patient
Where is protein synthesized?
the liver
malabsorption
occurs with malnutrition due to atrophy of gastric mucosa and loss of intestinal villi
H&H with malnutrition
May be low due to low albumin, anemia, infection, catabolism, or chronic disease
High values could indicate dehydration or hemoconcentration
Serum albumin
reflects nutritional status a few weeks before testing and is not the most sensitive study (should be 3.5-5.0)
Prealbumin
more sensitive indicator of protein deficiency because it has a short half life of 2 days. (normal is 15-36)
Transferrin
an iron transport protein with a short half life of 8-10 days which is also a sensitive indicator of protein status
