A nurse is providing discharge teaching to a new mother about newborn care. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale The umbilical cord stump typically dries, shrivels, and spontaneously separates from the infant's abdomen due to a process similar to dry gangrene (ischemic necrosis) within one to three weeks after birth; therefore, this statement indicates correct understanding of the normal timeline for cord care and healing. Choice B rationale A newborn's skin is sensitive and prone to drying, and daily tub baths are unnecessary and may cause skin irritation; sponge baths are used until the cord stump falls off, and then typically only two to three baths per week are recommended initially to maintain skin integrity. Choice C rationale The correct procedure for using a bulb syringe is to compress the bulb before insertion into the mouth (or nose) to create the negative pressure, then release the compression slowly to suction mucus; compressing it after insertion would expel air into the baby's mouth instead of suctioning. Choice D rationale Placing a baby on their side to sleep increases the risk of the baby rolling onto their stomach, which is associated with an elevated risk of Sudden Infant Death Syndrome (SIDS); the universally recommended safe sleep position is supine (on the back).
