Maternal Newborn ATI Quizlet

Correct Answer: C

Rationale: Plantar creases covering 2/3 of the sole is an important physical characteristic used to assess gestational age in a newborn. This finding is significant because as gestational age advances, the plantar creases cover a larger portion of the sole. It is a valuable clue to the healthcare provider in determining the newborn's maturity level. Choices A, B, and D are incorrect as they do not specifically relate to gestational age assessment. Acrocyanosis and vernix caseosa are common findings in newborns but are not directly used for determining gestational age. The softness and level of the anterior fontanel can provide information about intracranial pressure but are not directly related to gestational age assessment.

Correct Answer: A

Rationale: Assessing the firmness of the uterus is crucial in this situation. A uterus that is not firm could indicate postpartum hemorrhage, a common cause of low blood pressure after childbirth. By evaluating the firmness of the uterus, the nurse can quickly identify and address potential complications, such as excessive bleeding. Initiating oxygen therapy, administering oxytocin infusion, or obtaining a type and crossmatch may be necessary interventions later, but assessing the firmness of the uterus takes precedence as the first step in managing postpartum complications.

Correct Answer: D

Rationale: At 0 station, the lowermost portion of the fetus is at the level of the ischial spines, indicating that the presenting part of the baby has engaged in the pelvis. This position is a significant milestone in labor progress and suggests that the baby is descending into the birth canal for delivery. Choices A, B, and C are incorrect. Choice A refers to the fetal head position, choice B describes the largest fetal diameter passing through the pelvic outlet (which is not related to station), and choice C refers to the palpability of the posterior fontanel (which is not relevant to station in labor).

Correct Answer: B

Rationale: A surge of energy is a common sign that precedes labor. This burst of energy, often referred to as the 'nesting instinct,' is believed to occur as the body prepares for labor, prompting the individual to undertake tasks to prepare for the arrival of the baby. Decreased vaginal discharge is not a typical sign preceding labor. Urinary retention is not a sign that precedes labor and may indicate another issue. Weight gain of 0.5 to 1.5 kg is not a specific sign of impending labor.

Correct Answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.
