Final answer:
The nurse should anticipate the condition of Intrauterine Growth Restriction (IUGR) in an infant born to a client with chronic hypertension and superimposed preeclampsia who is below the average weight for a full-term newborn.
Step-by-step explanation:
A client with chronic hypertension and superimposed preeclampsia gives birth at 39 weeks' gestation to an infant weighing less than the average full-term birth weight. The nurse should anticipate the condition of Intrauterine Growth Restriction (IUGR).
The average weight of a full-term infant is approximately 3.4 kg (7.5 lbs), while a weight less than 2.5 kg (5.5 lbs) is considered low birthweight, often a result of IUGR. With hypertension and preeclampsia, the risk of developing IUGR increases due to potential placental insufficiency. If a newborn's birth weight is significantly below average, like in this case, it suggests that the baby has not achieved appropriate in-utero growth likely due to suboptimal conditions in the womb. Therefore, the nurse should anticipate the infant might be affected by IUGR, affecting their immediate and long-term health requiring careful monitoring and management.
