You are the nurse educator of the newborn nursery. Which behavior indicates a need for further education?

Correct Answer: C

Rationale: The correct answer is C. Placing the infant directly on the scale for weight measurement is incorrect as it can lead to inaccurate results due to factors like clothing or diaper weight. The correct method is to weigh the infant without clothing and then subtract the weight of the diaper. A: Heel stick method for blood glucose is appropriate. B: Placing an infant on phototherapy after swaddling is acceptable practice. D: Performing Ortolani and Barlow maneuvers in the supine position is also correct.

Correct Answer: B

Rationale: Correct Answer: B (Adequate prenatal care) Rationale: 1. Adequate prenatal care allows early detection and management of risk factors for premature birth. 2. Regular check-ups help monitor fetal development and address any complications promptly. 3. Education on healthy behaviors and nutrition can reduce the likelihood of premature birth. Summary of Incorrect Choices: A: High socioeconomic status - Although it may provide access to better healthcare, it does not directly prevent premature birth. C: Aid to Families with Dependent Children - Financial assistance does not directly address the medical care needed to prevent premature birth. D: WIC nutritional program - While nutrition is important, it alone may not be sufficient to prevent premature birth without proper prenatal care.

Correct Answer: A

Rationale: The correct answer is A because surfactant reduces surface tension in the alveoli, preventing alveolar collapse during expiration. This helps maintain alveolar stability and prevents atelectasis. Option B is incorrect because surfactant actually reduces alveolar permeability. Option C is incorrect as surfactant does not dilate bronchioles but affects alveolar stability. Option D is incorrect as surfactant's main role is in reducing surface tension, not in transporting oxygen.

Correct Answer: C

Rationale: The correct answer is C because a sustained respiratory rate of 70 breaths per minute indicates respiratory distress in a preterm infant. Gavage feedings are recommended in such cases to ensure adequate nutrition without causing further stress on the respiratory system. A: Sucking on a pacifier during gavage feedings is not a determining factor in choosing gavage over bottle feedings. B: Gagging when a feeding tube is inserted may not necessarily warrant gavage feedings over bottle feedings. D: The vital signs mentioned in choice D do not specifically indicate a need for gavage feedings; they may require further evaluation but are not a direct indication for gavage feedings.

Correct Answer: C

Rationale: The correct answer is C: lack of subcutaneous fat. Post-term infants who have lost weight in utero typically have decreased subcutaneous fat deposition, leading to a lean appearance. This is due to prolonged gestation and increased metabolic demands. Option A is incorrect as soft and supple skin is not specific to post-term infants. Option B is incorrect because a hematocrit level of 55% is not typical for a post-term infant. Option D is incorrect as an abundance of vernix caseosa is typically present in preterm infants, not post-term infants. Thus, the lack of subcutaneous fat is the most characteristic feature in this scenario.
