Question 1 of 5
For a pregnant adolescent who is anemic, which foods should the nurse include in the client's dietary plan to increase iron levels?
Correct Answer: C
Rationale: The correct answer is C: Orange juice and apricots. Orange juice is a good source of Vitamin C, which enhances iron absorption. Apricots are high in iron, helping to increase iron levels in the body. Milk and fish (choice
A) contain little iron. Chicken and cottage cheese (choice
B) are not significant sources of iron. Pickles and peanut butter sandwiches (choice
D) lack iron and Vitamin C.
Question 2 of 5
Which condition must occur in order for identical (monozygotic) twins to develop?
Correct Answer: C
Rationale: The correct answer is C: One sperm fertilizes one ovum. Identical twins result from the fertilization of a single egg by a single sperm, leading to the formation of a zygote that later splits into two embryos. This process results in genetically identical individuals.
Choices A, B, and D involve multiple fertilization events, which would lead to fraternal (dizygotic) twins with different genetic compositions.
Therefore, the only condition that can lead to the development of identical twins is when one sperm fertilizes one ovum.
Question 3 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 4 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 5 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.
