How many kilocalories per kilogram (kcal/kg) of body weight does a full-term formula-fed infant need each day?

Correct Answer: B

Rationale: A full-term formula-fed infant requires 100 to 110 kcal/kg per day to meet their nutritional needs. Providing less than 100 kcal/kg would be insufficient, while exceeding 110 kcal/kg could lead to overfeeding and potential health issues. It is important to ensure the correct amount of calories to support the infant's growth and development, making option B the most appropriate choice.

Correct Answer: D

Rationale: The correct answer is that a preterm infant has a greater surface area in proportion to their weight compared to a term infant. Preterm infants do not have more subcutaneous fat, well-developed flexor muscles, or few blood vessels visible through the skin. Understanding the differences between preterm and term infants is important in providing appropriate care for preterm infants.

Correct Answer: B

Rationale: Macrosomic infants are at risk for birth injuries, such as clavicle fractures, cephalohematomas, and brachial palsy. Evaluating for hyperglycemia and hyperthermia is important as well, but the priority assessment for a macrosomic infant would be to check for birth injuries, specifically clavicle fractures. An increase in red blood cells would not be the priority assessment in this scenario.

Correct Answer: B

Rationale: Nonphysiologic jaundice appears within the first 24 hours of life, while physiologic jaundice occurs after the initial 24 hours. Nonphysiologic jaundice may lead to kernicterus, progresses from head to body, and both types result from erythrocyte breakdown. Treatment needs to be timely to prevent kernicterus.
