Holder pasteurization - ANSWER-Rapidly heat and agitate the milk at 62.5C/144.5F for
30 mins
Qualitative studies focus on human experience; what is an example of a qualitative
study? - ANSWER-Phenomenology (also discourse analysis, ethnography, and
grounded theory are examples of qualitative studies)
What feeding regimen is appropriate for an infant with Phenylketonuria? - ANSWER-
Partial HM feedings and phenylalanine-free HM substitute supplements
Human milk is higher in whey proteins or casein? - ANSWER-Whey proteins (includes
albumin, a-lactalbumin, lysozyme, lactoferrin, IgA) are easily digestible by babies
Which method of breast surgery may interfere with the ability to breastfeed? -
ANSWER-Free-nipple breast reduction; blood supply of the nipple & areolas are
completely severed; this technique causes damage to nerves too, and severe milk ducts

of which ethnic group? - ANSWER-Southeast Asian (and Greek island extraction)
What is NOT true in comparing breastfeeding and bottle feeding? - ANSWER-
Breastfeeding suckling rate is slower than bottle feeding; (TRUE: breastfeeding
produces more frequent suckling, and mandibles jaw action)

What stage of lactation is controlled by the autocrine system and is the maintenance of
established secretion? - ANSWER-Lactogenesis 3/Galactoooiesis
Which are methods of quantitative research? - ANSWER-Randomized selection of

Antimicrobial, modulator of immune function and facilitator of nutrient utilization -
ANSWER-Leftover rib
A meta-analysis is what type of statistical technique? - ANSWER-Statistically combining
results from several similar, randomized control studies as if they were all part of one
big study
