A term neonate with a bih weight of 3980g showed the following feature. All of the following can be expected in this baby EXCEPT?
**Core Concept**
The question pertains to the physiological and anatomical changes that occur in a term neonate, specifically a baby born at 3980g. This weight is slightly above the average birth weight of 3000g, but still within the normal range. The question is asking about expected features in this baby, with the exception being the incorrect option.
**Why the Correct Answer is Right**
In a term neonate, the lungs are fully developed and capable of exchanging gases. The baby's respiratory system is mature, and the lungs are inflated with air at birth. This is in contrast to preterm babies, who often require respiratory support due to underdeveloped lungs. The baby's cardiovascular system is also mature, with a well-developed heart and functioning circulatory system. The kidneys are functioning, and the baby is able to excrete waste products. The baby's temperature regulation is also mature, with the ability to maintain a stable body temperature.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a feature that is not expected in a term neonate. Without more information, it is difficult to determine why this option might be incorrect.
**Option B:** This option is incorrect because it is a feature that can be expected in a term neonate. The baby's liver is functioning, and the baby is able to metabolize and excrete bilirubin.
**Option C:** This option is incorrect because it is a feature that can be expected in a term neonate. The baby's pancreas is functioning, and the baby is able to produce insulin and regulate blood glucose levels.
**Option D:** This option is incorrect because it is a feature that can be expected in a term neonate. The baby's gut is functioning, and the baby is able to digest and absorb nutrients.
**Clinical Pearl / High-Yield Fact**
A key feature of a term neonate is the presence of vernix caseosa, a waxy coating on the skin that provides protection and helps to regulate body temperature. This coating is typically absent in preterm babies.
**Correct Answer:** D. The gut is functioning in a term neonate, and the baby is able to digest and absorb nutrients.
