CBS CBS Breastfeeding Equipment & Technology 2 — Questions and Answers
Question 1: What is the recommended maximum storage duration for frozen breast milk in a dedicated deep freezer (0°F / -18°C) for a healthy term infant?
- 1 month
- 3 months
- 6 months (Correct answer)
- 12 months
Correct answer: 6 months
Human Milk Banking Association of North America (HMBANA) and AAP guidelines recommend using frozen breast milk within 6 months for optimal quality, though 12 months is acceptable.
Question 2: When cleaning pump parts that contact breast milk, which method is recommended as the minimum after each use?
- Wipe with a dry cloth
- Rinse with cold water only
- Wash with hot soapy water, rinse, and air dry (Correct answer)
- Sterilize in a microwave steam bag only
Correct answer: Wash with hot soapy water, rinse, and air dry
CDC guidelines recommend washing pump parts with hot soapy water, rinsing thoroughly, and air drying on a clean surface after each use.
Question 3: A supplemental nursing system (SNS) at the breast is most useful for:
- Measuring nipple size
- Delivering supplemental milk while the infant suckles at the breast (Correct answer)
- Preventing nipple confusion from bottles
- Sterilizing pump parts
Correct answer: Delivering supplemental milk while the infant suckles at the breast
An SNS delivers supplemental milk through a thin tube taped to the nipple, allowing the infant to receive extra nutrition while stimulating the breast.
Question 4: Which type of nipple is most likely to benefit from a silicone nipple shield to achieve latch?
- Protruding nipple
- Inverted nipple (Correct answer)
- Large nipple
- Cracked nipple
Correct answer: Inverted nipple
Inverted nipples do not protrude enough for the infant to latch effectively, and a nipple shield creates the needed projection for successful feeding.
Question 5: When thawing frozen breast milk, which method is safest?
- Microwave on high for 30 seconds
- Boil in a saucepan
- Thaw in the refrigerator overnight or under warm running water (Correct answer)
- Leave at room temperature for several hours
Correct answer: Thaw in the refrigerator overnight or under warm running water
Refrigerator thawing or warm running water preserves immunological properties; microwaving creates hot spots and degrades bioactive components.
Question 6: A hospital-grade double electric pump is distinguished from consumer-grade pumps primarily by:
- Its color and size only
- A closed system and motor designed for multi-user, long-duration use (Correct answer)
- Being sold exclusively online
- Using a different flange size
Correct answer: A closed system and motor designed for multi-user, long-duration use
Hospital-grade pumps have closed systems preventing milk backflow into the motor, making them safe for multiple users and capable of sustaining milk supply in NICU situations.
