What is a defining feature of premature infant skin?

Thick dermis with protective barrier
Very thin and susceptible to fluid loss
Fully functional stratum corneum at birth
Resistant to environmental factors

The correct answer is: Very thin and susceptible to fluid loss

The defining feature of premature infant skin is that it is very thin and susceptible to fluid loss. Premature infants have an underdeveloped skin structure, which includes a thinner epidermis and dermis compared to full-term infants. This thinness significantly compromises the integrity of the skin barrier, making them more vulnerable to transepidermal water loss. The limited development of skin lipids and proteins also contributes to their increased risk of dehydration and fluid imbalances. In contrast, a thick dermis with a protective barrier is characteristic of full-term infants, while a fully functional stratum corneum is not developed in premature infants, exposing them to higher risks of skin injury and infection. Additionally, premature infant skin is not resistant to environmental factors, making proper care and protection essential to mitigate risks associated with their condition.
