A newborn delivered at 41 weeks of gestation is showing signs of postmaturity. Which of the following findings is an indication of fetal postmaturity?

The correct answer is C: 'Thin with loose skin.' Postmature newborns are typically thin with loose skin due to prolonged gestation. This may result from placental insufficiency, leading to reduced subcutaneous fat stores. Choices A, B, and D are incorrect. Soft, flexible ear cartilage (choice A) is a normal finding in newborns. Smooth soles without creases (choice B) are also typical in newborns. Vernix caseosa covering the body (choice D) is a protective, waxy coating found on newborns, which may be present in postmature infants as well.
