Extract:
Question 1 of 5
What is the primary hormone responsible for maintaining the endometrium during pregnancy?
Correct Answer: A
Rationale: The correct answer is A: Progesterone. Progesterone is the primary hormone responsible for maintaining the endometrium during pregnancy. It helps thicken the endometrial lining to support implantation and nourishment of the embryo. Progesterone also inhibits contractions of the uterus to prevent premature labor. Estrogen, while important in preparing the endometrium for implantation, is not the primary hormone responsible for its maintenance during pregnancy. FSH and LH are involved in the menstrual cycle and ovulation but are not directly responsible for maintaining the endometrium during pregnancy.
Question 2 of 5
What is the recommended method of pain relief during labor for a woman with a high-risk pregnancy?
Correct Answer: A
Rationale: The correct answer is A: Epidural anesthesia. This is recommended for pain relief during labor in high-risk pregnancies as it provides effective pain relief while allowing the woman to remain alert and participate in labor. Epidural anesthesia can be adjusted as needed and does not affect the baby's heart rate. Spinal anesthesia is typically used for cesarean sections and may not be ideal for labor pain management. Intravenous opioids can cross the placenta and affect the baby's breathing and heart rate.
Choice D is incorrect because not all methods are recommended for high-risk pregnancies.
Question 3 of 5
A nurse is assessing a newborn 12 hr after birth. Which of the following manifestations should the nurse report to the provider?
Correct Answer: C
Rationale: Jaundice within the first 24 hours of life is considered pathological and should be reported to the provider, as it may indicate hemolytic disease or other serious conditions.
Question 4 of 5
A nurse is assessing a newborn who was born at 26 weeks of gestation using the New Ballard Score. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Minimal arm recoil. In premature newborns, particularly those born at 26 weeks of gestation, their muscle tone is typically low, leading to minimal arm recoil. This is a key characteristic assessed in the New Ballard Score to determine gestational age accurately. The other choices are incorrect because: B: A popliteal angle of 90° is more indicative of term infants; C: Creases over the entire foot sole are also seen in term infants; D: Raised areolas with 3 to 4 mm buds are features of newborns closer to term. Thus, A is the most appropriate finding for a newborn born at 26 weeks of gestation based on the New Ballard Score.
Question 5 of 5
A nurse is caring for a newborn immediately following birth. For which of the following reasons should the nurse delay the instillation of antibiotic ophthalmic ointment?
Correct Answer: D
Rationale: The correct answer is D:
To facilitate bonding between the newborn and parent. Delaying the instillation of antibiotic ophthalmic ointment allows for immediate skin-to-skin contact and bonding between the newborn and parent, which is crucial for establishing a strong emotional connection and promoting breastfeeding. This initial bonding period is a critical time for the newborn's development and emotional well-being.
Choices A, B, and C are incorrect because delaying the instillation of the ointment for these reasons could potentially jeopardize the newborn's health and increase the risk of infection.
