✍️ Sample IBCLC Questions & Answers

1. A weighted feed (test weight) is performed using which type of scale?

✓ Infant scale accurate to at least 2 grams

Test weighing requires a scale accurate to 2 grams or less because small changes in infant weight representing milk intake must be precisely measured.

2. Which feeding device most closely mimics breastfeeding pace to prevent flow preference in bottle-fed infants?

✓ Slow-flow bottle nipple with paced bottle feeding technique

Paced bottle feeding with a slow-flow nipple mimics the intermittent flow of breastfeeding and allows the infant to control the pace, reducing flow preference risk.

3. What is the function of Montgomery's tubercles on the areola?

✓ They secrete an oily substance that lubricates and protects the nipple and areola

Montgomery's tubercles are modified sebaceous glands that secrete a lipoid fluid that lubricates the areola and has antibacterial properties.

4. What is the recommended minimum number of breastfeeding sessions per day for a newborn in the first week?

✓ 8-12 times per day

Newborns should breastfeed a minimum of 8-12 times per 24 hours.

5. Which outcome measure is most relevant when evaluating the effectiveness of a hospital breastfeeding support program?

✓ Exclusive breastfeeding rates at hospital discharge

Exclusive breastfeeding rates at discharge directly measure the program's impact on the primary goal of supporting breastfeeding initiation and exclusivity.

6. A mother is concerned because her breastfed infant has yellow, seedy stools. She asks if this is normal. What is the correct response?

✓ Yellow, seedy stools are the normal stool pattern for exclusively breastfed infants

Yellow, seedy, loose stools are the normal stool pattern for exclusively breastfed infants.
