Correct Answer: B

Rationale: The ventrogluteal site is free of significant nerves and vascular structures, making it a safer choice for intramuscular injections in young children compared to other sites that may be more prone to complications.

Correct Answer: C

Rationale: The FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in infants and young children who are unable to verbally communicate their pain. This scale is particularly useful in assessing post-operative pain in infants as it evaluates different behaviors and physiological responses to pain. The Oucher scale is more commonly used with children who are older and can provide self-report of pain intensity. Wong-Baker FACES scale is primarily used with children who are older and can indicate their pain level by pointing to facial expressions. The 0-10 pain scale is typically used with older children and adults who can rate their pain on a numerical scale.

Correct Answer: B

Correct Answer: D

Rationale: The fluid requirement for a 14-kg child is approximately 100 mL/kg/day, so for a 14-kg child, the requirement is around 1400 mL/day.

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.
