# A nurse is teaching a first-time parent how to safely prepare and store powdered infant formula for a healthy term newborn before hospital discharge. The parent has no prior feeding experience and will exclusively bottle-feed at home. During teaching, the parent makes several statements about handling prepared formula bottles. Which statements indicate that the parent understands safe formula handling? Select all that apply. > source: MyMerci (mymerci.kr) > url: https://mymerci.kr/pages/nclex_q.php?qn_id=558425&lang=en > language: en > subject: Ante/Intra/Postpartum and Newborn Care > category: HPM ## Question A nurse is teaching a first-time parent how to safely prepare and store powdered infant formula for a healthy term newborn before hospital discharge. The parent has no prior feeding experience and will exclusively bottle-feed at home. During teaching, the parent makes several statements about handling prepared formula bottles. Which statements indicate that the parent understands safe formula handling? Select all that apply. 1 I will discard any formula left in the bottle once my baby finishes a feeding instead of saving it for later. 2 I will freeze extra prepared formula in ice cube trays so it lasts longer before the next feeding. 3 If I prepare a bottle and my baby has not started feeding from it, I will refrigerate it promptly and use it within twenty-four hours. 4 I will warm a refrigerated bottle by placing it in a bowl of warm water for a few minutes before feeding. 5 I will keep an unopened prepared bottle in the refrigerator for up to forty-eight hours before using it. 6 I will reuse the same prepared bottle for multiple feedings throughout the day, refrigerating it between each use. ## Explanation The parent should discard formula left after a feeding because the infant's saliva promotes bacterial growth (Choice 1). A prepared bottle that has not been offered can be refrigerated promptly and used within 24 hours (Choice 3). A refrigerated bottle may be warmed in a bowl of warm water and checked before feeding (Choice 4). Prepared formula should not be frozen to extend storage (Choice 2), should not be kept refrigerated for 48 hours (Choice 5), and must not be reused across feedings after the infant has drunk from it (Choice 6). ## In-depth explanation Correct Answer Choices 1, 3, 4 Clinical Reasoning The parent should discard formula left after a feeding because the infant's saliva promotes bacterial growth (Choice 1). A prepared bottle that has not been offered can be refrigerated promptly and used within 24 hours (Choice 3). A refrigerated bottle may be warmed in a bowl of warm water and checked before feeding (Choice 4). Prepared formula should not be frozen to extend storage (Choice 2), should not be kept refrigerated for 48 hours (Choice 5), and must not be reused across feedings after the infant has drunk from it (Choice 6). Option Review - Correct — Discarding formula that remains after a feeding prevents bacterial growth introduced by the infant's saliva, which prepared formula cannot safely tolerate beyond that feeding. - Incorrect — Freezing prepared formula is not necessary for safe storage and can cause separation or texture changes; refrigeration alone is sufficient for short-term storage. - Correct — Prepared formula that has not been offered to the infant may be refrigerated promptly and used within 24 hours. Once feeding begins, the infant's saliva changes the discard limit. - Correct — Warming a refrigerated bottle in a bowl of warm water heats the formula evenly and avoids the uneven heating pattern that other rapid-warming methods can create. - Incorrect — Holding a prepared bottle in the refrigerator for forty-eight hours exceeds the recommended twenty-four-hour window, giving bacteria more time to grow than is considered safe. - Incorrect — Reusing the same prepared bottle for more than one feeding, even when refrigerated between uses, repeatedly exposes the formula to bacteria introduced from the infant's mouth.
