-Can only be accessed through the anteroom or another buffer room

29
Q

What is a segregated compounding area (SCA)?

A

Not required to be classified

-Designed with a visible perimeter
-Must contain a primary engineering control and is only for sterile compounding of Category 1 CSPs

30
Q

Category 1,2, and 3 CSPs must be compounded in at least what ISO class?

A

ISO Class 5 or better

31
Q

What does a laminar airflow system do?

A

Provides ISO Class 5 or better environment

Unidirectional HEPA-filtered airflow

32
Q

True or False: Beyond Use Dates (BUD) and Expiration Dates are the same?

A

FALSE

33
Q

What is an expiration date?

A

Date assigned by the manufacturer based on the analytical and performance testing of the sterility, chemical, and physical stability an packaging integrity of the product

-Specific to a particular formulation in its container at stated exposure of illumination and temperature

34
Q

What factors are used to establish a beyond use date?

A

Chemical and physical stability

Container closure system materials and compatibility with the final prep

35
Q

What considerations should be made when using Single-dose containers?

A

-Not required to meet antimicrobial effectiveness testing

-Only puncture in ISO 5 or cleaner air

-Use up to 12 hours after initial entry

-Opened single doe ampuls must not be stored

36
Q

What considerations go into using Multiple-Dose Containers?

A

-Once punctured it must not be used for > 28 days

37
Q

What considerations go into using Pharmacy Bulk Packages?

A

-Restricted to sterile preparation of admixtures for infusion or through a sterile transfer device, for filling empty sterile containers

-Time of use is per labeling

-Only puncture in ISO 5 or cleaner air

38
Q

Based on the OLD <797> guidelines, immediate use products must be administered within how much time following the start of the preparation?

A

40
Q

Which form of nutrition has more costs and complications associated with it? Parenteral or Enteral?

A

Parenteral

41
Q

What are crystalline amino acids?

A

Purer amino acids than protein hydrolysates

47
Q

What is the least stable vitamin in solution?

Longer stability

Increased number of compatible medications

49
Q

53
Q

What is an infection that neonates can get from catheter contamination or a fat emulsion environment?

A

Malassezia furfur

-can occur from the normal flora of adults

54
Q

Which element can pose a risk with parenteral nutrition due to PN bypassing the GI barrier that normally prevents its absorption?

A

Aluminum

55
Q

Who is at risk of being harmed by aluminum in PN?

A

Neonates

Impaired renal function

56
Q

What is the FDA limit on aluminum in Large Volume Products (LVPs)?

A

25 mcg/L

56
Q

which substance has the higher aluminum concentration: Glass or Plastic?

A

Glass

57
Q

What volume should be used for Large Volume Parenterals (LVP)?

A

25 mcg/L

58
Q

Which two electrolytes in PN can precipitate with each other to form a chalky substance?

A

Calcium

Phosphate

59
Q

Which ingredient in PN can obscure precipitates and how does this affect the way we make 3-in-1 bags?

A

Lipids obscure precipitates

When making a 3-in-1, add calcium before the fat so you are able to see if any precipitates of calcium and phosphate form before it is obscured by lipids
