Nursing Care of the Newborn Quizlet Questions
Question 1 of 5
Blood flow connection between the systemic, aorta, pulmonary blood flow, and pulmonary artery is which fetal shunt?
Correct Answer: C
Rationale: The correct answer is C: ductus arteriosus. During fetal circulation, the ductus arteriosus allows blood to bypass the lungs by connecting the pulmonary artery to the aorta. This shunt is crucial for directing blood from the right side of the heart to the systemic circulation. The other choices are incorrect because: A: The ductus venosus shunts blood from the umbilical vein to the inferior vena cava, bypassing the liver. B: The foramen ovale allows blood to pass directly from the right atrium to the left atrium, bypassing the lungs. D: There is no structure known as foramen venosus in fetal circulation.
Question 2 of 5
At birth, a newborn weighed 6 pounds, 12 ounces. Three days later, the newborn weighs 5 pounds, 10 ounces. What conclusion should the nurse draw regarding this newborn's weight?
Correct Answer: C
Rationale: The correct answer is C: This weight loss is excessive. The newborn's weight decreased from 6 lbs 12 oz to 5 lbs 10 oz in just three days, indicating a significant loss. A newborn typically loses around 5-10% of their birth weight in the first few days. This weight loss exceeds the expected range, suggesting potential issues like inadequate feeding or dehydration. Choices A and B are incorrect because the weight loss is not within normal limits, and weight gain is not observed. Choice D is incorrect as there is no weight gain, let alone excessive weight gain.
Question 3 of 5
What condition can result from a long, difficult labor and is characterized by a localized, soft area on the newborn's head?
Correct Answer: A
Rationale: The correct answer is A: caput succedaneum. This condition occurs due to pressure on the baby's head during a long and difficult labor. It is characterized by a soft, localized swelling on the newborn's head. The other choices are incorrect. B: molding refers to the shaping of the baby's head during passage through the birth canal. C: depressed fontanelles indicate dehydration or malnutrition. D: cephalohematoma is a collection of blood between the baby's skull and periosteum, usually due to birth trauma.
Question 4 of 5
The nurse notices that a 6-hour-old newborn patient's urethral opening is on the dorsal side of the penis. The nurse knows that this is called what?
Correct Answer: B
Rationale: The correct answer is B: epispadias. In epispadias, the urethral opening is located on the dorsal side of the penis. This condition is a congenital anomaly where the urethra fails to fully close during fetal development. Hypospadias (choice A) is when the urethral opening is on the underside of the penis. Phimosis (choice C) is the inability to retract the foreskin. Unispadias (choice D) is not a recognized medical term. Therefore, the nurse correctly identifies the condition as epispadias due to the specific presentation of the urethral opening on the dorsal side of the penis in the 6-hour-old newborn patient.
Question 5 of 5
The nurse is assessing a newborn girl born at 40 weeks of gestation based on the parent's LMP. What assessment finding of the genitalia confirms this gestational age?
Correct Answer: A
Rationale: The correct answer is A because at 40 weeks of gestation, the labia majora should completely cover the clitoris and labia minora. This is known as the "laboratory majora sign" and is characteristic of full-term newborns. Choice B is incorrect because a prominent clitoris and enlarged labia minora indicate a younger gestational age, typically around 36-38 weeks. Choice C is incorrect as small labia minora and enlarged clitoris suggest a preterm newborn, around 32-34 weeks. Choice D is incorrect as enlarged labia majora and small labia minora are more indicative of a post-term newborn, around 42 weeks or more. Overall, the correct answer, choice A, aligns with the expected genitalia findings for a newborn born at 40 weeks of gestation based on the parent's LMP.
