IBCLC Practice Exam Question Concepts Q&A
Protein binding - =Plasma protein is the most important factor that determines drug
penetration into milk. High protein binding drugs have difficulty entering the milk. It is the free
component that is floating in the mother's plasma that transfer into the milk rather than the
protein bound part of the drug (this part stays in the maternal circulation)
How long should hormonal contraception be avoided after birth? - =4-6 weeks due to risk of
blood clots and decreased milk production
Important communication tips - =Always important to validate parent's concerns first and then
ask open-ended questions to get to the root of the parent's concern
Risk factors for hypoglycemia - =cold stress, gestational diabetic mother, and infant low birth
weight
At what age does child led weaning typically occur? - =30-60 months (2.5-7 years)
What is a p-value? - =P-value is the probability of seeing the research based on chance alone. if
a p-value is <5 % (p<.05, .01, or .001), then there is a statistically significant finding
What age does pincer grasp usually emerge? - =9 months
When does milk intake amounts remain relatively consistent? - =From 6 weeks to 6 months of
age
What components of milk increase in value with someone with mastitis? - =Sodium increases
the most, lactoferrin and chloride values also increase. Sodium increases are caused by the
temporary openings of the usual tight junctions between secretory cells
,What are optimal breastfeeding positions for infants with recessed chin? - =prone or side lying
position
What is the pharynx and where is it located? - =It is the muscle lined space that connects the
nose and mouth to the larynx and esophagus (eating tube)
What is the larynx and where is it located? - =This is the voice box that contains voice cords
Cranial Nerve I (name, sensory or motor and function) - =Olfactory; Sensory; smell
Cranial Nerve II (name, sensory or motor and function) - =Optic; Sensory; Vision
Cranial Nerve III (name, sensory or motor and function) - =Oculomotor; Motor; eye movement,
pupil constriction
Cranial Nerve IV (name, sensory or motor and function) - =Trochlear Nerve; motor; vertical eye
movement
Cranial Nerve V (name, sensory or motor and function) - =Trigeminal Nerve; Both ;
somatosensory think facial sensation, information (touch, pain) from face and head; muscles for
chewing
Cranial Nerve VI (name, sensory or motor and function) - =Abducens Nerve; motor; lateral eye
movement
Cranial Nerve VII (name, sensory or motor and function) - =Facial Nerve; both; taste (anterior
2/3 of tongue), controls muscles used in facial expression
Cranial Nerve VIII (name, sensory or motor and function) - =Vestibulocochlear nerve; sensory;
hearing balance
, Cranial Nerve IX (name, sensory or motor and function) - =Glossopharyngeal Nerve ; both; taste
(posterior 1/3 of tongue); somatosensory information from tongue, tonsil, pharynx, controls
some muscles used in swallowing
Cranial Nerve X (name, sensory or motor and function) - =Vagus Nerve; both; sensory, motor,
and autonomic functions of viscera; gag reflex
Cranial Nerve XI (name, sensory or motor and function) - =Spinal Accessory Nerve; motor;
controls muscles used in head movement (head and shoulder movement)
Cranial Nerve XII (name, sensory or motor and function) - =Hypoglossal Nerve; motor; controls
muscles of tongue
Levels of milk per day by 2nd or 3rd week - =590-750 mL (20-25 oz)
levels of milk per day by 4th-5th week of life - =750-1035 mL (25-35 oz); this volume remains
stable until 6 months of age
once lactation is established after 3 months, how often must milk removal occur per 24 hours? -
=milk removal can be every 4 hours (6 times in 24 hours)
infant average feed volume for first week of life - =first day: 2-10 mL
second day: 5-15 mL
third day: 15-30 mL
fourth day: 30-60 mL
what is lactogenesis I? - =-occurs around 16 weeks of pregnancy
-epithelial cells of the alveoli differentiate into secretory cells; cell membranes of alveoli are
leaky and lead to higher plasma concentration of lactose and lactoalbumin
