Correct Answer: B

Rationale: Palpating the fundus of the uterus during Leopold maneuvers is crucial to identify the fetal lie. This technique allows the nurse to determine the position of the baby's back and locate the fetal heart sounds, aiding in assessing the fetal lie. Choices A, C, and D are incorrect as they do not directly relate to identifying the fetal lie during Leopold maneuvers. Applying palms to the sides of the uterus or grasping the lower uterine segment do not provide the necessary information about the fetal lie. Standing facing the client's feet and outlining cephalic prominence is more related to assessing the fetal presentation, not the fetal lie.

Correct Answer: A

Rationale: In a newborn with respiratory distress syndrome who has received synthetic surfactant, monitoring oxygen saturation is crucial to evaluate the effectiveness of the treatment. Oxygen saturation levels provide valuable information about the newborn's respiratory status and the adequacy of gas exchange. Changes in oxygen saturation can indicate improvements or deterioration in the newborn's condition following the administration of synthetic surfactant. Monitoring oxygen saturation helps the nurse assess the newborn's response to treatment and make timely interventions if needed. Body temperature, serum bilirubin, and heart rate are important parameters to monitor in newborns for other conditions but are not specific indicators of the effectiveness of synthetic surfactant in treating respiratory distress syndrome.

Correct Answer: B

Rationale: The classification of a newborn as appropriate for gestational age is determined by considering the weight and gestational age. In this case, the newborn's weight falls within the normal range for the gestational age, indicating that the newborn is appropriately sized for the length of time spent in the womb. Choice A, 'Low birth weight,' is incorrect as the newborn's weight is within the normal range. Choice C, 'Small for gestational age,' is incorrect because the newborn's weight is not below the 10th percentile for gestational age. Choice D, 'Large for gestational age,' is incorrect as the newborn's weight is not above the 90th percentile, rather falling within the 60th percentile which is considered normal.

Correct Answer: A

Rationale: Individuals with phenylketonuria (PKU) have difficulty breaking down phenylalanine, an amino acid found in protein-rich foods like peanut butter. Therefore, clients with PKU should avoid foods high in phenylalanine, such as peanut butter, to prevent adverse effects on their health. Choices B, C, and D are not typically high in phenylalanine and do not pose the same risk to individuals with PKU as peanut butter.

Correct Answer: D

Rationale: Providing reinforcement about infant care when the parent is present can help alleviate anxiety and promote positive parent-infant bonding. By offering guidance and support while the parent is interacting with the newborn, the nurse can help build the parent's confidence and strengthen the bond between the parent and the infant. Choice A is not ideal as it does not address the parent's anxiety and may increase stress levels. Choice B focuses on the parent's emotions without providing direct support for bonding. Choice C is dismissive and does not offer practical assistance in fostering bonding between the parent and the infant.
