PN BASICS
This nutrition method supplies all nutrients directly into the bloodstream.
What is parenteral nutrition?
Adults unable to ingest at least this percentage of required calories within 7 days may require PN.
What is 50 percent?
This central vein is preferred for rapid dilution of hypertonic PN solutions.
What is the superior vena cava?
A 2-in-1 PN solution requires this micron filter.
What is a 0.22-micron filter?
The most serious infection associated with PN central lines.
What is CLABSI?
PN solutions contain proteins, carbohydrates, fats, electrolytes, vitamins, trace minerals, and this essential component.
What is sterile water?
PN is indicated sooner—within 3 to 5 days—for patients who are already in this nutritional state.
What is malnourished?
A PICC is inserted into a peripheral vein but terminates in this central location.
What is the right atriocaval junction?
Lipid emulsions require this micron filter due to fat particle size.
What is a 1.2-micron filter?
Sudden PN discontinuation can cause this life-threatening complication.
What is rebound hypoglycemia?
The primary goals of PN include improving nutritional status, promoting healing, and achieving this metabolic state.
What is a positive nitrogen balance?
A patient with paralytic ileus, short-bowel syndrome, or high-output fistula fits this PN indication.
What is impaired ability to ingest or absorb nutrients?
PN solutions should NOT be infused through peripheral veins when dextrose exceeds this percentage.
What is 10 percent?
A 3-in-1 PN solution is also known by this name.
What is total nutrient admixture (TNA)?
PN infusing too rapidly may cause this renal-driven fluid loss mechanism.
What is hyperosmolar diuresis?
PN should be considered only after this preferred nutrition route is deemed not feasible.
What is enteral nutrition?
PN is indicated when enteral nutrition would compromise this protective function of the GI tract.
What is gut mucosal integrity?
This access site should be avoided for PN due to high infection risk.
What is the femoral vein?
PN solutions must be discarded if they appear separated or show this dangerous visual finding.
What is precipitate or a cracked solution?
Air entering the venous system during catheter insertion can cause this emergency.
What is air embolism?
PN differs from IV fluids because it provides sufficient calories and protein to meet this daily patient need.
What are total nutritional requirements?
Severe burns, trauma, and sepsis increase caloric needs due to this metabolic state.
What is hypermetabolism?
The patient is placed in this position during central line insertion to reduce air embolism risk.
What is Trendelenburg position?
Lipid emulsions can provide up to this percentage of total daily calories.
What is 30 percent?
The FIRST nursing action if PN solution runs out unexpectedly.
What is start D10W at the same rate?
