Correct Answer: A

Rationale: The correct answer is A. Human milk is the preferred food for infants, including preterm infants. It contains essential ingredients necessary for the infant's growth and development. The mother should pump her breasts to provide milk for the infant if the child is receiving enteral feedings. Once the infant can coordinate breathing, sucking, and swallowing, breastfeeding directly is encouraged. Studies have shown that preterm infants fed fortified human milk have better outcomes compared to those fed commercial infant formulas. Commercial infant formulas may not fully meet the unique nutritional needs of preterm infants, leading to potential longer hospital stays. Therefore, human milk is the best choice for feeding premature infants.

Correct Answer: A

Correct Answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

Correct Answer: B

Rationale: Pain management should be based on the child's report of pain, regardless of their activity level. Administering the prescribed analgesic is the appropriate action. Reassessing the child in 15 minutes without providing immediate pain relief may not be in the child's best interest. Doing nothing since the child appears to be resting may lead to inadequate pain management. Asking the child's parents if they think the child is hurting does not replace the need for direct assessment and intervention by the nurse.

Correct Answer: B

Rationale: Protecting the skin around the colostomy is crucial to prevent irritation and infection, which are common complications in infants with colostomies. Teaching and discussing long-term implications are important but secondary to immediate skin care needs.
