IBCLC Practice Questions (2026) — Free Sample Questions with Answers

Answer: A

Low milk intake, since this stool and urine pattern fits days 1–2, not day 5: Correct: by day 5 stools should be turning yellow and wet diapers increasing to about 6 or more. Dark sticky stool and powdery orange-pink urate staining past day 3–4 suggest inadequate intake, so the IBCLC observes a feed, weighs the infant today and informs the provider.

Normal day-5 output, since meconium often continues through the first week: Wrong period: meconium should have changed to yellow stools by about day 4–5; this pattern fits days 1–2, and waiting risks dehydration and jaundice.

Bleeding from the urinary tract, shown by the orange-pink stain on the lining: Misinterpretation: a powdery orange-pink stain fits urate crystals in concentrated urine, a sign of low intake, not bleeding.

Constipation, since the thick, sticky stool shows the stool is drying out: Near-sibling: thick, sticky, greenish-black stool is meconium that has not yet transitioned, a sign of low intake rather than constipation.

Period: 3 - 14 days; Task: Evaluate. By day 4–5, expect yellowing stools and rising wet diapers; meconium and urate staining at day 5 point to low intake and call for same-day feeding and weight assessment.

Answer: B

She is below the 3rd percentile and needs supplements to catch up: Chronological-age error: the app plotted her at 4 months, ignoring that she was born 8 weeks early.

At a corrected age of 2 months she is tracking between the 15th and 50th percentiles: Correct: 16 weeks − (40 − 32) weeks = 8 weeks, a corrected age of about 2 months. Her 4.8 kg sits between the 15th (4.5 kg) and 50th (5.1 kg) lines, and her earlier points follow the same channel.

She is on the 50th percentile, so her growth needs no further plotting: Misread: she was on the 50th line only at term; at 2 months corrected she is between the 15th and 50th, and growth should keep being plotted.

Correction is no longer needed because she is now past her due date: Wrong rule: preterm infants are plotted by corrected age until about 24 months, not only until the due date.

Period: Prematurity (including late preterm); Task: Evaluate. Corrected age = chronological age − weeks born early; plot preterm infants on WHO charts by corrected age until about 2 years.

Answer: B

Move the infant into a cradle hold now and guide the mouth onto the nipple: Right goal, wrong method: the infant is mid-way through the self-attachment sequence; taking over interrupts it and often leads to a shallower latch.

Keep skin-to-skin uninterrupted and let the infant continue toward the breast: Correct: head bobbing, hand-to-mouth sucking, drooling and stepping movements are the newborn's instinctive pre-feeding behaviours. BFHI Step 4 calls for immediate, uninterrupted skin-to-skin, with routine procedures delayed until after the first feed.

Weigh and bathe the infant first, then return the infant skin-to-skin to feed: Wrong order: weighing and bathing should wait until after the first feed; separation now interrupts the feeding sequence.

Swaddle the infant and offer the breast once the fist-sucking settles: Misread cue: fist-sucking is an early feeding cue, not a reason to wait, and swaddling ends skin-to-skin contact.

Period: Labour - maternal / birth - perinatal; Task: Visual examination of the breastfeeding infant's position and latch. Head bobbing, fist-sucking and stepping movements in the first hour are the newborn's self-attachment sequence; protect uninterrupted skin-to-skin until the first feed is complete.

Answer: A

Help the mother breastfeed now, then give her stored colostrum after the feed: Correct: the infant is at risk (maternal diabetes, large for gestational age) but has no symptoms and is rooting. Effective early breastfeeding followed by the mother's own expressed colostrum, with the recheck per protocol, is first-line (ABM #1).

Thaw and give the colostrum before breastfeeding, to raise glucose faster: Wrong order: the infant is rooting and ready to feed, so breastfeeding comes first; the colostrum can thaw during the feed and be given afterward, so no time is lost.

Give formula by bottle now, and keep the stored colostrum for later days: Wrong supplement: the mother's stored colostrum is the first-choice supplement for exactly this situation, and nothing indicates a need for formula.

Move the infant to the nursery for observation while the mother rests: Unneeded separation: an asymptomatic infant stays skin-to-skin, which also helps stabilize glucose.

Period: 0 - 2 days; Task: Develop a plan. For an asymptomatic at-risk newborn: breastfeed early and often, then give the mother's expressed colostrum, recheck per protocol, and keep the dyad together.

Answer: A

Pumping after every feed on top of breastfeeding: Correct: routine pumping after feeds drives hyperlactation, a major predisposing factor across the mastitis spectrum (ABM #36).

Breastfeeding 8–10 times a day on infant cues: Normal: cue-based feeding at this frequency is expected and protective.

Freezing her extra milk instead of discarding it: Irrelevant: what she does with the milk afterward does not affect the breast.

Feeding from both breasts with a deep latch: Protective: effective feeding from both sides is what the plan should keep.

Period: 15 – 28 days; Task: History taking. Routine pumping after every feed on top of breastfeeding drives oversupply, a key driver of ductal narrowing and mastitis (ABM #36).

Answer: C

1. Change in dressed weight: 3,416 g − 3,412 g = 4 g.
2. Weight removed by the diaper swap: soiled 28 g − fresh 8 g = 20 g.
3. Intake = 4 g + 20 g = 24 g; at 1 g ≈ 1 mL, about 24 mL.

4 mL: Forgot the diaper change: 3,416 − 3,412 = 4 g ignores the 20 g that left in the soiled diaper.

20 mL: Counted only the diaper difference: 28 − 8 = 20 g leaves out the 4 g rise in the infant's weight.

24 mL: Correct: weight change 3,416 − 3,412 = 4 g; the diaper swap removed 28 − 8 = 20 g; intake = 4 + 20 = 24 g, about 24 mL.

32 mL: Did not subtract the fresh diaper: 4 + 28 = 32 g counts the 8 g fresh diaper as lost weight.

Period: 3 - 14 days; Task: Evaluate. Test-weigh intake = post-feed weight − pre-feed weight, corrected for anything removed or added between weighings (1 g ≈ 1 mL).

Answer: D

Apply an antifungal cream after each feed, as the color changes suggest thrush: Near-sibling: a white-blue-red color sequence with cold-triggered throbbing is not the shiny pink skin of candida.

Use a cold pack on the nipple straight after each feed to numb the pain: Worsens it: cold triggers the blood-vessel spasm behind this color change.

Switch to a nipple shield to protect the nipple during and after each feed: Not indicated: the latch is deep and painless; the problem begins after the feed.

Keep the nipple warm after feeds, and refer her about the color change: Correct: color change from white to blue to red with throbbing after feeds, triggered by cold and with pale fingertips, fits vasospasm. Warmth straight after feeds and avoiding cold help; the provider assesses for treatment.

Period: 1 - 3 months; Task: Visual examination of the breastfeeding mother's nipple and breast. White-blue-red nipple color change after a good latch, triggered by cold, calls for warmth after feeds and referral, not antifungals or cold packs.

Answer: D

Medicine P: RID too high: 14% is above the roughly 10% level generally considered acceptable, even though the half-life is short.

Medicine Q: Accumulation risk: the low RID is offset by a very long-acting active metabolite, which can build up in a newborn whose clearance is immature.

Medicine R: Acceptable but not best: RID under 10% and no metabolite, but a longer half-life and higher exposure than S.

Medicine S: Correct: short half-life, very low RID, poor oral absorption by the infant and no active metabolite give the lowest infant exposure. The physician makes the choice; the IBCLC supplies the lactation data.

Period: 3 - 14 days; Task: Work with other healthcare providers. Favorable lactation profile: low RID (well under 10%), short half-life, low oral bioavailability and no long-acting active metabolite, especially for newborns.

Answer: D

Move the bassinet into a separate nursery so the parents' movements do not wake the infant: Wrong direction: room-sharing on a separate surface, ideally for at least the first 6 months, is recommended (AAP 2022).

Keep the towel roll but raise the head of the mattress further to reduce spit-up: Unsafe: positioners and inclined sleep surfaces are not recommended, and spit-up is not a reason for them.

Swap the quilt for a lighter blanket tucked firmly under the mattress at chest level: Outdated: AAP 2022 advises no blankets or soft items in the sleep space; a wearable blanket can be used instead.

Lay the infant on the back on the flat, firm mattress, with only a fitted sheet: Correct: side sleeping, a towel roll, a sheepskin, a quilt, a bumper and an incline are all risk factors. Back sleeping on a firm, flat, bare surface in the parents' room is the AAP 2022 recommendation; reflux is not a reason to change it.

Period: 15 – 28 days; Task: Verbal communication with breastfeeding families. Back to sleep on a firm, flat, bare surface in the parents' room; no positioners, bumpers, soft bedding or inclines.

Answer: C

1. The diaper is the same for both weights, so no correction is needed.
2. Weight after both breasts − weight before the feed = 2,690 g − 2,650 g = 40 g.
3. 1 g of weight gain ≈ 1 mL of milk, so the infant took about 40 mL from the breast.
4. The 15 mL given by cup was after the post-feed weight and is not breast intake.

14 mL: Right breast only: 2,690 − 2,676 = 14 g counts only the second breast.

26 mL: Left breast only: 2,676 − 2,650 = 26 g counts only the first breast.

40 mL: Correct: 2,690 − 2,650 = 40 g, and 1 g of weight gain is about 1 mL of milk.

55 mL: Added the supplement: the 15 mL given by cup came after the breast feed and is not intake from the breast (40 + 15 = 55).

Period: Prematurity (including late preterm); Task: Evaluate. Test-weigh intake = weight after the whole feed − weight before it, in the same clothing; 1 g ≈ 1 mL.

Answer: C

Lift the infant into the cot so the drowsy parent can sleep without the infant on the chest: Second step, not first: the infant's breathing and colour must be checked right away; ending skin-to-skin is an option only if no one can stay to watch the infant.

Leave the dyad undisturbed, since skin-to-skin in the first hours helps the infant stabilize: Misses the danger: skin-to-skin is beneficial only when the infant's face is visible, the airway is clear and an alert adult is watching.

Check the infant's breathing and colour, then turn the head so the face is visible: Correct: a flexed head, a covered face and a drowsy, unobserved parent are risk factors for sudden unexpected postnatal collapse. The first action is to check the infant and reposition so the face is visible and the neck is not bent forward; then arrange observation.

Wake the parent and teach the early feeding cues so the next feed is not missed: Wrong priority: feeding education can wait until the infant has been checked and repositioned.

Period: 0 - 2 days; Task: Visual examination of the breastfeeding infant's position and latch. Safe skin-to-skin requires a visible face, a clear nose and mouth, a head that is not flexed, and an alert observer; check and reposition before anything else.

Answer: B

Telephone support increases exclusive breastfeeding at both 6 weeks and 6 months: Misreads the interval: at 6 months the 95% CI (0.89–1.53) includes 1, so an effect is not shown.

It increases exclusive breastfeeding at 6 weeks, but a 6-month effect is not shown: Correct: at 6 weeks the CI (1.12–1.49) excludes 1, showing a benefit; at 6 months the CI includes 1, so the trial does not show an effect at that point (which is not the same as showing no effect).

Telephone support has no proven benefit, because the 6-month exclusive result was not significant: Overgeneralizes: one non-significant outcome does not cancel the significant 6-week result.

Telephone support reduces exclusive breastfeeding over time, as the rate fell from 62% to 21%: Wrong comparison: the fall over time happened within the group; effects are judged between groups.

Period: General principles (including preconception); Task: Develop a plan. A risk ratio whose 95% CI excludes 1 shows an effect; one that includes 1 means the effect is not shown, not that it is absent.

Answer: A

Location A: Correct: milk should be stored at the back of the refrigerator (or freezer), where the temperature is coldest and most stable, not in the door (CDC). Fresh milk for the next day does not need freezing.

Location B: Door shelf: the temperature rises every time the door opens; the CDC advises against storing milk in the door.

Location C: Freezer door: freezing is not needed for milk used the next day, and the door is the least stable part of the freezer.

Location D: Front of the shelf: inside the main compartment, but warmer air reaches it each time the door opens; the back is better.

Period: 1 - 3 months; Task: Verbal communication with breastfeeding families. Store milk at the back of the refrigerator or freezer, never in the door; refrigerated fresh milk keeps up to 4 days (CDC).

Answer: B

Ask the member privately to stop attending, since the comments could discourage newcomers: Excludes too soon: the member's experience is valid, and the misinformation can be addressed within the group.

Acknowledge the member's experience, note that ongoing pain needs help, and invite others: Correct: a facilitator validates the member, corrects the misinformation gently, and opens the discussion, so newcomers hear accurate information and the group stays safe.

Let the discussion continue without comment, since peer groups should be led by members: Leaves misinformation: the facilitator is responsible for accurate information in the group.

Correct the member firmly in front of the group so that newcomers hear the right information: Right content, wrong manner: public correction shames the member and makes others less likely to share.

Period: General principles (including preconception); Task: Verbal communication with breastfeeding families. In group support, validate experiences, correct misinformation gently, and keep the discussion open.
