Correct Answer: C

Rationale: When a newborn experiences a tight nuchal cord during delivery, it can lead to petechiae, which are small red or purple spots on the skin caused by bleeding under the skin. These petechiae may appear over the head, face, and neck due to the pressure of the cord. It is essential for the nurse to recognize this as a possible consequence and monitor the newborn for any signs of complications. Bruising over the buttocks (Choice A) is not typically associated with a tight nuchal cord. Hard nodules on the roof of the mouth (Choice B) are more indicative of Epstein pearls or Bohn's nodules, which are considered normal findings in newborns. Bilateral periauricular papillomas (Choice D) are not related to a tight nuchal cord but are seen in congenital syphilis.

Correct Answer: C

Rationale: The correct answer is C. The nurse should advise the client to empty her bladder before an amniocentesis to minimize the risk of bladder puncture during the procedure. This precaution helps ensure the safety and accuracy of the procedure by reducing potential complications related to bladder puncture. Choices A, B, and D are incorrect because lying on the right side, fasting for 24 hours, and determining gestational age are not relevant instructions for an amniocentesis procedure.

Correct Answer: A

Rationale: To calculate the estimated date of delivery, add 7 days to the first day of the last menstrual period (April 1st), which gives April 8th. Then, count forward 9 months from April 8th, leading to January 8th as the estimated date of delivery. Choice A is correct. Choice B is incorrect because it is exactly 9 months from the last menstrual period without accounting for the additional 7 days. Choices C and D are incorrect as they fall in February, which is beyond the 9-month period from the last menstrual period.

Correct Answer: D

Rationale: The correct answer is D: All of the Above. Multiple risk factors can contribute to preterm labor, including urinary tract infection, multifetal pregnancy, and oligohydramnios. These factors can lead to the uterus being irritated or overstimulated, potentially triggering early labor. Urinary tract infections can cause inflammation and contractions, multifetal pregnancies have a higher risk of preterm labor due to increased uterine stretching, and oligohydramnios can lead to poor fetal growth and premature contractions. Therefore, clients presenting with these conditions require close monitoring and management to prevent preterm birth. Choices A, B, and C are all correct risk factors for preterm labor, making option D the correct answer.

Correct Answer: D

Rationale: The correct answer is D. Clients who do not like milk should continue taking calcium supplements to ensure they meet their increased calcium needs while breastfeeding. Calcium is essential for bone health, and during breastfeeding, the mother's calcium requirements are higher. While caffeine in coffee can be consumed in moderation, folic acid does not directly impact milk supply, and the additional 330 calories per day are recommended but not the focus of this question.
