| Question | Answer |
|---|---|
| TPN does what | provides an alternate nutrition route in cases of severe gastrointestinal distress and/or poor nutrition absorbtion |
| TPN (also known as) | Hyperlimentation -hyperals |
| What is the average time of administration for TPN | 10-12 hrs |
| TPN is made between the range of _ml-__L | 500-4 |
| what is the average volume of TPM | 3-4 |
| what are the 7average ingredients in a TPN_____,_____,_____,_____,_____,_____,______ | *sugar*lipids*trace elements*carbs*electrolytes*protein*amino acids |
| Base ingredients in a TPN(4)_______,______________,__________________,____________________________ | *amino acids *dextrose 70/50*sterile water*lipids20 |
| the most common source of calories in TPN are (2)_________________,____________________ | dextrose, fat |
| each gram of dextrose provides _________kcal | 3.45 |
| lipids are avail in what % concentrations | 10/20/30 |
| what lipid concentration can be infused directly into the vein__________which one must be admixed in IV_______ | 10/20/30 |
| a healthy patients caloric support is best provided as a mixed fuel with __-__%of the calories derived from dextrose and __-__% fat | 50/80 20/50 |
| each gram of fat provides ____kcal | 9 |
| amino acids defined | building blocks of proteins |
| amino acids help provide ________________________________________________ | enough nitrogen for the patient |
| what is PROTOCAL | the standard plan for a course of medical treatment |
| factors considered when deciding on a peripheral or central line(8) | *type of medication*osmolarity/pH of solution to be administered*duration of therapy*dx of med condition of patient*patient references*avail/condition of patients vein*patient history*secondary risk factors |
| hyperglycemia | too high a level of glucose |
| hypoglycemia | too low a level of glucose |
| In re: to TPN, why remove filters | proteins will stick to the filters altering the dose |
| In re: to base ingredients-which additive should be added last | lipids |
| how many additives can a micromix compounder add | 10 |
| Phosphate supplementation(potassium phosphate) is often incompatable with calcium | it causes a formation of an insoluable salt |
| Which hood are TPNs usually compounded | LAH |
| TPN is broken down into 2 elements | base/additives |
| FYI for TPN volume scenario | it is better to choose a bag that is too big vs too small |
| what is a Viaflex bag | an empty IV bag |
| When adding base ingredients to bag -what is the order | dextrose/amino acids/lipids/ SWFI |
| Why should lipids be added last in a TPN | because it is opaque white |
| amino acids act as a buffer between what 2 elements | dextrose/lipids |
| why does amino acids act as a buffer | to minimize a possible chemical reaction |
| which ADDITIVE should be added first | potassium phosphate |
| which ADDITIVE should be added next to last | calcium gluconate |
| which ADDITIVE is added last | multivitaminMVI |
