Correct Answer: A

Rationale: Correct. Placenta previa typically presents with painless vaginal bleeding as the placenta is located over or near the cervical opening. This bleeding occurs because the placental vessels are stretched and bleed easily. Severe abdominal pain (choice B) is not a typical finding in placenta previa. Uterine contractions (choice C) are more characteristic of preterm labor rather than placenta previa. Increased fetal movement (choice D) is not a specific finding associated with placenta previa.

Correct Answer: B

Rationale: A contraction duration of 90 seconds can indicate uterine tachysystole, which may lead to fetal hypoxia. Uterine tachysystole is defined as more than five contractions in 10 minutes, averaged over a 30-minute window. Contractions every 2 minutes (Choice A) may occur in active labor but need to be assessed in conjunction with other factors. A fetal heart rate of 150/min (Choice C) is within the normal range. Urine output of 60 mL/hr (Choice D) is also within the expected range for a client in labor.

Correct Answer: A

Rationale: A respiratory rate of 70/min in a newborn is above the expected range and may indicate respiratory distress, which should be reported to the provider. Choice B, vernix caseosa covering the skin, is a normal finding in newborns and does not require reporting. Choice C, milia on the bridge of the nose, is also a common finding in newborns and does not require immediate reporting. Choice D, acrocyanosis of the extremities, is a common finding within the first few hours of life in newborns and typically resolves on its own, so it does not need to be reported.

Correct Answer: B

Rationale: The correct action the nurse should take first when observing variable decelerations in the fetal heart rate is to reposition the client from side to side. Variable decelerations are often caused by umbilical cord compression, and repositioning the client can relieve pressure on the cord. Administering oxygen, increasing the IV infusion rate, and notifying the provider can be appropriate actions but repositioning the client takes priority in addressing variable decelerations.

Correct Answer: A

Rationale: The correct answer is A: 'Blood pressure 80/50 mm Hg.' Hypotension can be a side effect of oxytocin administration. A blood pressure of 80/50 mm Hg should be reported to the provider. Choice B, 'Uterine contractions,' is an expected finding as oxytocin is used to stimulate uterine contractions. Choice C, 'Urine output 150 mL in 2 hours,' is within the expected range postpartum. Choice D, 'Client reports cramping,' is a common finding due to uterine contractions and is not a cause for concern unless excessive or severe.
