The nurse determines that the teaching is effective when the students state that the preterm newborn has greater surface area in proportion to weight. The correct option is D.

<h3>What is a preterm newborn?</h3>

Preterm babies are those born early before the 37th week of pregnancy. Preterm birth is split into subcategories based on gestational age: exceptionally premature less than 28 weeks extremely premature 28 to 32 weeks

Premature babies may experience more health problems at conception and later in life than full-term babies.

Premature babies are more likely to have long-term intellectual and developmental disabilities, as well as issues with their lungs, brain, eyes, and other organs.

When the educators state that the preterm newborn has a larger surface area in proportion to weight, the nurse knows the teaching is effective.

Thus, the correct option is D.
