Explanation

Vernix caseosa is the correct term for the waxy, cheese-like white substance found coating the skin of newborn babies.
It is composed of sebum (oily substance from sebaceous glands) and desquamated epithelial cells (shed skin cells).
Its primary role is to protect the fetus's skin from constant exposure to amniotic fluid in the womb.
Post-birth, it acts as a natural moisturizer, provides antibacterial properties, and aids in thermoregulation.

Option A: Lanugo is the fine, soft, downy hair that covers a fetus or newborn. It is a type of hair, not a cheesy substance.
Option C: Amniotic fluid is the liquid that surrounds the fetus inside the amniotic sac. It is a fluid, not a coating on the skin.
Option D: Brown fat is a specialized type of adipose tissue located internally in newborns (e.g., around the neck and shoulders) that is metabolized for heat production. It is not a substance found on the skin.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of normal physiological characteristics of a newborn's skin as background academic context rather than a clinical decision trigger.
Nurses should educate parents that vernix is a natural moisturizer with protective properties. It is recommended to delay the newborn's first bath for at least 24 hours to allow the vernix to be absorbed, which helps prevent dry skin and provides antibacterial benefits.
The amount of vernix is an indicator of gestational age. Preterm infants have more, while post-term infants (born after 42 weeks) have little to none, often presenting with dry, peeling skin.
What if? If a newborn has meconium-stained vernix (greenish or yellowish), it indicates fetal distress occurred in utero. The nursing action would be to thoroughly assess the infant's respiratory status, as there is a risk of meconium aspiration syndrome.

How to Approach the Question

First, carefully read the question and identify the key descriptive phrase: 'white cheesy material on the skin of newborn'.
Break down the description into keywords: 'white', 'cheesy', 'on the skin', 'newborn'. This points to a specific substance present at birth.
Evaluate each option based on your knowledge of neonatal characteristics.
Consider 'Lanugo'. This is fine hair, not a cheesy substance. Eliminate this option.
Consider 'Vernix caseosa'. This term directly translates to 'cheesy varnish' and matches the description perfectly.
Consider 'Amniotic fluid'. This is the liquid the baby is suspended in before birth, not a coating on the skin. Eliminate this option.
