Question 1

A TPN order specifies 70 mEq of potassium chloride per liter. The available stock is KCl 2 mEq/mL. How many mL of KCl must be added?

Accepted Answer

35 mL

Answer

Using the formula: Volume = Amount ÷ Concentration = 70 mEq ÷ 2 mEq/mL = 35 mL of KCl.

Question 2

Which of the following best describes the purpose of using a 0.22-micron filter when administering a 2-in-1 TPN (without lipids)?

Accepted Answer

To remove particulate matter and bacteria

Answer

A 0.22-micron filter removes particulate matter, bacteria, and fungi from 2-in-1 TPN solutions, providing an important final safety check before administration.

Question 3

When compounding a 3-in-1 TPN admixture, what is the CORRECT order of component addition to minimize the risk of calcium-phosphate precipitation?

Accepted Answer

Dextrose → Phosphate → Amino acids → Calcium → Lipids

Answer

Adding dextrose first, then phosphate followed by amino acids and calcium last (before lipids) ensures the components are well-diluted before potentially reactive ions meet.

Question 4

Which type of IV admixture preparation error involves adding the correct drug in the correct amount but to the WRONG patient's bag?

Accepted Answer

Wrong patient error

Answer

A wrong patient error occurs when a correctly prepared product is assigned or delivered to the wrong patient, often due to insufficient verification during compounding.

Question 5

For peripheral parenteral nutrition (PPN), the maximum final osmolarity recommended to prevent phlebitis is approximately:

Accepted Answer

900 mOsm/L

Answer

PPN solutions should generally not exceed 900 mOsm/L to minimize the risk of phlebitis and vein damage from hyperosmolar solutions.
