Question:
Rapid intravenous infusion of potassium phosphate may result in
Answer:
Thrombophlebitis
Question:
most common complication associated with PN administration?
Answer:
Hyperglycemia
Question:
The preferred approach for subcutaneous insulin administration
Answer:
Basal-bolus insulin therapy
Question:
Which form of glutamine supplementation improves physical compatibility and stability for
admixture in PN solutions?
Answer:
Glutamine Dipeptide
Question:
,Which of the following additives has the greatest risk of destabilizing the lipid injectable emulsion
(ILE) in a total nutrient admixture (TNA)?
Answer:
Iron dextran- The higher the cation valence, the greater the destabilizing power; thus, trivalent
cations such as Fe+3 (from iron dextran) are more disruptive than divalent cations such as calcium
and magnesium.
Question:
A complete PN order shall contain the following
Answer:
complete patient identifiers, birth date or age, allergies, height and dosing weight in metric units,
diagnosis/diagnoses, indication(s) for PN, administration route/vascular access device (peripheral
versus central), contact information for prescriber, date and time order submitted, administration
date and time, volume and infusion rate, infusion schedule (continuous or cyclic), and type of
formulation (TNA versus dextrose/amino acids with separate ILE).
Question:
PN ingredients shall be ordered as follows:
Answer:
amounts per day (for adult patients) or amounts per kilogram per day (for pediatric and neonatal
patients), electrolytes as complete salt form, full generic name for each ingredient, dose for each
macronutrient and electrolyte, dose for vitamins (including MVI and individual entities), dose for
trace elements (including multi-components and/or individual entities), dose for each non-nutrient
medication.
Question:
Which of the following is a indication for the use of parenteral nutrition (PN)? 1: High output fistula
2: Crohn's disease 3: Pancreatitis 4: Hyperemesis gravidarum
Answer:
1: High output fistula
,Question:
The routine use of preoperative parenteral nutrition (PN) is indicated for patients with a
non-functioning GI tract who are
Answer:
significant reductions in perioperative complications are achieved in the severely malnourished
patient receiving more than 7 days of preoperative PN.
Question:
TNA are more likely to be stable for 30 hours at _______ or for 9 days ________ followed by 24
hours at ___________
Answer:
room temperature, refrigerated, room temperature.
Question:
ILE administered via piggyback separate from amino acid and dextrose should have a hang time of
Answer:
12 hours and have tubing and filter changes with each new infusion. Recently package inserts for
ILE have been updated to state that 1.2 micron filters should be used during ILE administration.
Question:
A peripherally inserted central catheter (PICC) is defined as a catheter inserted via peripheral vein
whose distal tip lies in the
Answer:
Superior vena cava
Question:
PICC line disadvantages include:
Answer:
, high rate of malposition or coiling; limited patient arm mobility associated with limited ability to
perform daily self-care due to the availability of only one hand; and longer catheter that may be
more prone to occlusion.
Question:
Advantages of PICC lines include:
Answer:
no risk of pneumothorax or puncture or internal carotid or subclavian arteries; available in single,
double, and triple lumens; and repeated skin puncture is not required.
Question:
A common complication of central venous catheters inserted at the bedside is
Answer:
catheter misplacement, including pneumothorax.
Question:
The use of fluoroscopy during catheter insertion allows
Answer:
immediate repositioning of the catheter tip to its correct location in the superior vena cava.
Question:
central catheters placed at bedside without fluoroscopy should be
Answer:
radiographically confirmed and documented in the medical record before initial use.
Question:
replacement of temporary catheters during bacteremia should not be done over a guidewire due to
