TPN Exam 1, Questions and answers,
2022/2023. 100% verified. Rated A
what is the purpose and indication of parental nutrition? - ✔✔the purpose of TPN is to deliver nutrients
Indication are if pt. is unable to use GI tract and if they have a potential of developing malnutrition and
nota candidate for enteral therapy
what are the components of parental nutrition? - ✔✔-carbs, proteins, fats, vitamins, minerals, trace
minerals
what are the types of parental therapy? - ✔✔1. partial parental nutrition
2. Total parental nutrition
what is partial parental nutrition? - ✔✔-needs to be administered through a large peripheral vein of the
arm
-administer throguh a PICC line
-solutions: IV fat emulsions (lipid) and amino acids and dextrose (AA/D 300-900 m/osm)
-AA/D = 2.1 mixture
what is total parental nutrition? - ✔✔-administration through central veins
-administered through PICC Line , subclavian, or internal jugular
-solutions: synthetic AA/protein hydrolysate (3% to 5%)
-osmolarity: 900-1800 mOsm
-IVFE + AA/D = 3:1
what are some contraindications for TPN? - ✔✔-significant malnutrition; comprised renal/hepatic status
-fluid restricted patients
-phlebitis due to high solution osmolarity
, why is nitrogen balance important? - ✔✔because it is a sensitive indicator to know what protein is doing
what is catabolism? - ✔✔destrictive phase; breaking down, state of starvation)
what is anabolism? - ✔✔building protein --> wound healing
what does a positive nitrogen balance mean? - ✔✔taking in more, retaining protein
-anabolic state (net gain of protein)
what does a negative nitrogen balance mean? - ✔✔when you have less protein
-state of starvation (body needs more protein that what it has- body uses other sources of energy
(catabolic state- state of starvation)
what is a 2 in 1 mixture? - ✔✔dextrose and amino acids (in one bag)
fat emulsions infused simultaneously (in bag #2)
-IVEF are isotonic
-use a 0.22 micronfilter
(two filters, two pumps)
what is a 3 in one mixture? - ✔✔-contains dextrose, AA's, and fat emulsions
-milky white, opaque, faint yellow
-components compounded aseptically in the pharmacy
-less manipulation
-less risk of ocntamination
-less nursing time required
-use 1.2 micron filter (all in one pump)
