Question 1 of 5
Which fetal structure is responsible for carrying oxygenated blood from the placenta to the fetus?
Correct Answer: D
Rationale: The correct answer is D: Umbilical vein. The umbilical vein carries oxygenated blood from the placenta to the fetus. This is because the placenta acts as the organ of gas exchange during fetal development. Oxygenated blood from the mother is transferred to the fetus through the umbilical vein. The other choices are incorrect because:
A) Ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs.
B) Umbilical artery carries deoxygenated blood from the fetus to the placenta.
C) Portal vein carries nutrient-rich blood from the intestines to the liver, not from the placenta to the fetus.
Question 2 of 5
A client at 33 weeks gestation is admitted for suspected abruptio placenta. Which factor in the client's history supports this diagnosis? The client states that she:
Correct Answer: D
Rationale: The correct answer is D: used crack an hour before the symptoms began. Abruptio placenta is a condition where the placenta prematurely separates from the uterine wall. Substance abuse, such as crack cocaine, can lead to vasoconstriction and increased risk of abruptio placenta due to compromised blood flow to the placenta. This can result in fetal distress and maternal bleeding. The other choices (A, B,
C) do not directly correlate with abruptio placenta. Intermittent contractions relieved by walking are more suggestive of Braxton Hicks contractions, intercourse is not a known risk factor for abruptio placenta, and drinking wine does not typically cause this condition.
Question 3 of 5
Which explanation is most appropriate when describing physiological jaundice to the parents of a newborn?
Correct Answer: B
Rationale: The correct answer is B: The baby is breaking down the extra red blood cells that were present at birth. Physiological jaundice in newborns occurs due to the breakdown of excess red blood cells, leading to an increase in bilirubin levels. This is a normal process as the baby's liver is still maturing.
Choice A is incorrect because minor blood incompatibility usually leads to a condition known as hemolytic disease of the newborn, not physiological jaundice.
Choice C is incorrect as breast milk does not cause physiological jaundice.
Choice D is incorrect because hepatitis B exposure does not directly cause physiological jaundice in newborns.
Question 4 of 5
A woman at 42 weeks gestation enters the hospital for induction of labor. Since the infant is postterm, which complications should the nurse anticipate when planning for the delivery?
Correct Answer: B
Rationale: The correct answer is B: Asphyxia and meconium aspiration. At 42 weeks gestation, the risk of perinatal asphyxia increases due to decreased placental function. Meconium aspiration can occur if the fetus passes stool in utero, leading to respiratory distress. The other choices are not directly related to postterm pregnancy complications. Cephalopelvic disproportion and hypothermia (
Choice
A) are not specific to postterm pregnancy. Intraventricular hemorrhage and dry, cracked skin (
Choice
C) are not commonly associated with postterm pregnancies. Hyperbilirubinemia and hypocalcemia (
Choice
D) are more likely to occur after birth and are not directly related to being postterm.
Question 5 of 5
Which method of temperature regulation would safely and effectively prevent cold stress in a newly delivered infant?
Correct Answer: C
Rationale: The correct answer is C: Cover the baby's head with a hat. Infants lose a significant amount of heat through their heads, so covering the head with a hat helps prevent heat loss and cold stress. Option A does not provide enough insulation to prevent cold stress. Option B only addresses the feet, while the head is a major heat loss area. Option D poses a risk of overheating and burns.
