Final answer:
The nurse can anticipate Respiratory Distress Syndrome (RDS) based on the findings observed during the newborn assessment.
Step-by-step explanation:
Based on the findings observed by the nurse when assessing the newborn, the complication that the nurse can anticipate is Respiratory distress syndrome (RDS). RDS is a condition that affects premature infants and is characterized by difficulty in breathing due to underdeveloped lungs. The slow recoil of the pinnae and few sole creases indicate immaturity of the baby's connective tissues, which is a common feature of infants with RDS. The arms and legs slightly flexed position and abundant lanugo on the back are also indicative of prematurity, which increases the risk of RDS.
