Final answer:
The nurse should expect hypoglycemia, tachycardia, and hypertonicity as manifestations in a hypothermic newborn. Flushed skin is not a typical manifestation of hypothermia.
Step-by-step explanation:
The nurse should expect hypoglycemia as a manifestation in a 1-hour-old newborn with hypothermia. Hypoglycemia refers to low blood sugar levels, which can result from decreased body temperature in newborns. Hypothermia can impair the newborn's ability to regulate glucose levels, leading to hypoglycemia.
Other manifestations that the nurse may expect in a hypothermic newborn include tachycardia, which is a rapid heart rate, and hypertonicity, which refers to increased muscle tone or stiffness. These manifestations are the body's responses to maintain body temperature and compensate for the cold stress.
Flushed skin is not a typical manifestation of hypothermia. Instead, the baby's skin may appear pale or mottled due to decreased blood flow to the extremities.
