Question 1

Which complication is associated with too-rapid infusion of hypertonic dextrose in a TPN solution without adequate insulin?

Accepted Answer

Hyperglycemia

Answer

Rapid infusion of concentrated dextrose in TPN can cause hyperglycemia if insulin coverage is insufficient.

Question 2

What is the maximum recommended final concentration of dextrose in a peripherally administered IV admixture?

Accepted Answer

12.5%

Answer

Peripheral parenteral nutrition should not exceed 12.5% dextrose to avoid phlebitis and vein damage.

Question 3

Which amino acid solution component is responsible for providing nitrogen in TPN formulations?

Accepted Answer

Crystalline amino acids

Answer

Crystalline amino acid solutions provide the nitrogen needed for protein synthesis and tissue maintenance in TPN.

Question 4

A compounding technician notices that a TPN admixture has a yellowish oily layer floating on top. This most likely indicates:

Accepted Answer

Lipid emulsion cracking or breaking

Answer

A floating oily layer in a 3-in-1 TPN indicates that the lipid emulsion has cracked (phase-separated), making it unsafe for use.

Question 5

Which vitamin is typically added to TPN separately and protected from light due to its photosensitivity?

Accepted Answer

Vitamin A

Answer

Vitamin A is highly photosensitive and degrades rapidly when exposed to light, requiring light-protected IV tubing or bags.
