Cards

Term
In 1996, what did the joint commission mandate in regards to nutrition screening on newly admitted patients? is this universally accepted?

must be performed on them within 24 hours of admission. no, there is no universally accepted approach to identify and diagnose malnutrition
Term
how does the american society for parenteral and enteral nutrition define screening?
Definition
a process to identify an individual who is malnourished or who is at risk for malnutrition to determine if a detailed nutrition assessment is needed
Term
When it comes to nutrition screening tools, is a smaller grade number or larger number characteristic of the highest sensitivity and specificity? which tools on the PPT had the best sensitivity and specificity for the patient populations studied?

Term
What are albumin and pre albumin good for when assessing nutrition?
Definition
-albumin: good indicator of poor nutritional status in an ambulatory patient without any other significant medical problem, but in patients we now see admitted, it is not reliable indicator and not typically used in screens or assessment
-prealbumin: can be used to MONITOR the efficacy of the prescribed nutrition support, should be combined with acute phase reactant (like CRP) to determine inflammation and stress levels

what is the half life of albumin?
Definition
3 weeks
Term
what are the two screening panels important in getting a complete picture of nutritional status?
Definition
CBC
CMP
Term
what type of pt is glucose monitored in? who gets insulin orders?
Definition
ALL
everyone gets at least a sliding scale insulin orders if they demonstrate 1 BG above normal
Term
Who are lipid panels important for?
Definition
most important in IV nutrition
but CHO levels can be used as indicator of nutritional status
Term
Who are lipid panels important for?
Definition
most important in IV nutrition
but CHO levels can be used as indicator of nutritional status
Term
When are blood gases and acid base disorders considered daily? What aspect of these measurements can be negatively affected by overfeeding?
Definition
when pt's are intubated-- if on PN adjustments are made to address acidosis or alkalosis
-on EN: overfeeding can affect the P-CO2 values negatively
Term
Which two acute phase proteins will rise when a pt is in a pro inflammatory state? what are the function of each?
Definition
CRP: scavenger of cell membrane debris; complements DNA activation
ceruloplasmin: binds copper, antioxidant
Term
What are the 4 acute phase proteins that do not rise when a pt is in a pro-inflammatory state? what is the function of each?
Definition
-albumin: binds Ca and other molecules; antioxidant, plasma oncotic pressure
-prealbumin: thyroxine transport; forms complex with RBP
-transferrin: iron absorption and transport
-IGF: promotes protein synthesis in liver & muscle; inhibits lipolysis
Term
negative acute phase proteins are excellent indicators of what?
Definition
the severity of illness, NOT nutritional status. may predict those at risk for malnutrition
Term
what is a positive pump sign? what does this mean?
Definition
trauma patient with more than 5 pumps
means they are severely ill
Term
When it comes to inflammation, is nutrition support alone effective in prevention of muscle protein loss? what are indicators of inflammation?
Definition
-no
-biomarkers (CRP, albumin), obesity, hyperglycemia, organ failure
Term
what is starvation related malnutrition?
Definition
chronic starvation without inflammation (anorexia)
Term
what is chronic dz related malnutrition?
Definition
inflammation is chronic and of a mild to moderate degree (RA, organ failure, pancreatic CA)
Term
what is acute disease or injury-related malnutrition?
Definition
inflammation is acute and of a severe degree (major infection, burns, trauma, closed head injury)
Term
define REE, BEE, BMR, RMR
Definition
-REE: energy expended for normal body functions (the amount of energy required to maintain vital organ function in a resting state over 24 hours)
-BEE: minimal energy expended required for life
-BMR: measured in morning before eating and activity (the minimum caloric requirement at a neutral environmental temperature and fasting)
-RMR: may include energy for digestion and oxygen consumption of tissues
Term
what is considered the gold standard for estimating nutritional requirements? what does it measure
Definition
indirect calorimetry (measures REE and RQ)
Term
What is the respiratory quotient? what is the normal range? what is it a good marker of?
Definition
-the ratio between CO2 produced and O2 consumed
-normal physiologic dance is 0.67-1.3 (she says .7-1)
