Which type of formula should not be diluted before being administered to an infant?

Correct Answer: C

Rationale: The correct answer is C: Ready to use. Ready to use formula should not be diluted before being administered to an infant because it is already in the appropriate concentration for consumption. Diluting it further could result in the infant not receiving the necessary nutrients in the right proportions, potentially leading to nutritional deficiencies or other health issues. Explanation of why other choices are incorrect: A: Powdered formulas are designed to be mixed with water according to specific instructions provided by the manufacturer, so they should be diluted before administering to an infant. B: Concentrated formulas are meant to be mixed with water before feeding to the infant, so they should be diluted as per the instructions. D: Modified cow's milk should be diluted as it is not suitable for infants in its concentrated form and needs to be appropriately prepared according to guidelines provided by healthcare professionals.

Correct Answer: A

Rationale: The correct answer is A: Unwrap and gently arouse the infant. This action is important to prevent the infant from falling asleep immediately after feeding, as it may lead to inadequate intake and poor weight gain. By gently arousing the infant, the mother can encourage the baby to feed for a longer duration, ensuring proper nourishment. Choices B, C, and D are incorrect because waiting an hour before attempting to feed again may result in long gaps between feeds, offering a bottle at the next feeding may not address the immediate issue of inadequate feeding, and putting the infant in the crib and trying again later does not actively address the problem of the infant falling asleep too quickly after feeding.

Correct Answer: D

Rationale: Step 1: The correct answer is D because it accurately explains the concept of milk supply and demand. Step 2: As the baby demands more milk at each feeding, the mother's body will naturally increase milk production to meet the demand. Step 3: This is the biological principle of supply and demand in breastfeeding. Step 4: Option A is incorrect because early addition of baby food is not related to milk production. Step 5: Option B is incorrect because breast milk composition remains relatively constant; it doesn't become richer as the baby grows. Step 6: Option C is incorrect because cow's milk is not recommended as a supplement for infants due to its composition being unsuitable for their digestive systems.

Correct Answer: D

Rationale: The correct answer is D because breast milk can be kept refrigerated for up to 72 hours. This is important to ensure the milk stays fresh and safe for the baby. Thawing and refreezing breast milk (Choice A) can lead to nutrient loss and contamination. Freezing breast milk for up to 6 months (Choice B) is not recommended as it can affect the quality of the milk. Storing breast milk only in glass bottles (Choice C) is not necessary as breast milk can be stored in BPA-free plastic bottles or storage bags specifically designed for breast milk.

Correct Answer: B

Rationale: The correct answer is B because colostrum is crucial for newborns as it is rich in antibodies, proteins, vitamins, and minerals essential for the baby's health and immune system. Colostrum provides vital nutrients and protective factors that help the baby fight infections and establish a healthy gut microbiome. It acts as the baby's first vaccine and is crucial for their overall well-being. Choice A is incorrect because colostrum is necessary for newborns due to its unique composition. Choice C is incorrect as colostrum is not lower in calories, and it is not necessary to supplement with formula. Choice D is incorrect as the primary purpose of giving colostrum is to benefit the newborn's health, not just for the mother's learning process.
