A nurse is preparing to assess a newborn who is postmature. Which of the following findings should the nurse expect?
Cracked, peeling skin
Abundant lanugo
Short, soft fingernails
Abundant vernix .
The Correct Answer is A
Choice A rationale: A postmature newborn, or one born after 42 weeks of gestation, is likely to exhibit cracked, peeling skin due to the prolonged exposure to amniotic fluid and the absence of vernix. This makes Choice A the correct answer, as it reflects the expected findings for a postmature newborn.
Choice B rationale: Abundant lanugo is typically seen in preterm infants, not postmature infants. Lanugo is a fine, downy hair that covers the fetus and usually disappears by 37 weeks of gestation. Therefore, Choice B is not an expected finding for a postmature newborn.
Choice C rationale: Short, soft fingernails are characteristic of preterm infants. In postmature infants, fingernails are generally long and may extend beyond the fingertips due to prolonged gestation. This makes Choice C an incorrect answer for the expected findings of a postmature newborn.
Choice D rationale: Abundant vernix is typically seen in preterm and term infants. Vernix is a white, cheesy substance that covers the fetal skin to protect it from amniotic fluid. Postmature infants usually have minimal to no vernix present, as it has already been absorbed. Therefore, Choice D is not an expected finding for a postmature newborn.

Correct Answer is B
Explanation
Choice A rationale
Intermittent abdominal pain following the passage of bloody mucus can be a sign of labor or other complications, but it is not a typical finding that supports the diagnosis of placenta previa.
Choice B rationale
Painless red vaginal bleeding is a classic symptom of placenta previa. This occurs because the placenta is covering part or all of the cervix, leading to bleeding as the cervix begins to thin and open in preparation for labor.
Choice C rationale
Abdominal pain with scant red vaginal bleeding could indicate various conditions, but it is not a typical finding that supports the diagnosis of placenta previa.
Choice D rationale
Increasing abdominal pain with a non-relaxed uterus could indicate various conditions, but it is not a typical finding that supports the diagnosis of placenta previa.
Correct Answer is D
Explanation
Choice A rationale
While blunt force trauma can cause placental abruption, it is not the most common risk factor. Trauma can lead to abruptio placentae, but this is more likely in cases of severe injury.
Choice B rationale
Cigarette smoking is a risk factor for many pregnancy complications, including placental abruption. However, it is not the most common risk factor.
Choice C rationale
Cocaine use can cause abrupt vasoconstriction and is a risk factor for placental abruption. However, it is not the most common risk factor.
Choice D rationale
Hypertension is the most common risk factor for placental abruption. Chronic hypertension, gestational hypertension, and preeclampsia can all contribute to the risk of developing this condition.
