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 C
Explanation
The correct answer is Choice C.
Choice A rationale: A respiratory rate of 16/min is within the normal range for an adult and does not indicate immediate concern.
Choice B rationale: A headache can be a symptom of preeclampsia, but it is not as immediate a concern as the other options unless it is severe or accompanied by other symptoms.
Choice C rationale: A urinary output of 40 ml in 2 hours is significantly below the normal range. Oliguria (low urine output) can be a sign of renal impairment and magnesium toxicity, which requires immediate reporting to the healthcare provider.
Choice D rationale: A fetal heart rate of 158/min is within the normal range for a fetus and does not indicate immediate concern.
Correct Answer is C
Explanation
Choice A rationale
Inserting a urinary catheter is not typically the first action when the fundus is displaced. It is more commonly done when the bladder is distended and the patient is unable to urinate.
Choice B rationale
Massaging the fundus is usually done when the uterus is soft or boggy to help it contract and prevent postpartum hemorrhage. However, in this case, the fundus is firm, indicating that the uterus is well contracted.
Choice C rationale
Having the patient urinate is the appropriate action when the fundus is displaced to the right of the midline. This displacement often indicates a full bladder, which can push the uterus to the side. After the patient urinates, the uterus often returns to the midline position.
Choice D rationale
Administering an analgesic is not the first action when the fundus is displaced. Pain medication is typically given for postpartum discomfort or afterbirth pains, not for a displaced fundus.
