Nursing Care of the Newborn Quizlet Questions
Question 1 of 5
A breastfeeding mother asks the postpartum nurse if any supplementation is necessary once her breast milk comes in. What is the nurse's most appropriate response?
Correct Answer: C
Rationale: The correct answer is C because breast milk is indeed low in vitamin D, and supplementation with 400 IU is recommended to ensure the baby's needs are met. Choice A is incorrect as it focuses on the mother's concerns rather than the baby's nutritional needs. Choice B is irrelevant to the specific question about vitamin supplementation. Choice D is incorrect as breast milk lacks sufficient vitamin D, necessitating supplementation.
Question 2 of 5
Transient tachypnea of the neonate develops due to what pathophysiologic phenomenon?
Correct Answer: A
Rationale: The correct answer is A because transient tachypnea of the neonate is primarily caused by the failure to clear lung fluid by the usual mechanism. During birth, the baby may not expel the lung fluid properly, leading to respiratory distress. This results in rapid breathing (tachypnea) due to the retained fluid in the lungs. The other choices are incorrect as they do not directly relate to the pathophysiology of transient tachypnea. Choice B involves the heart (patent ductus arteriosus), choice C relates to insufficient surfactant production seen in respiratory distress syndrome, and choice D mentions meconium aspiration syndrome, which is a different condition caused by the aspiration of meconium into the lungs, not related to the failure to clear lung fluid.
Question 3 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 4 of 5
The nurse recommends skin-to-skin contact immediately following the birth of a newborn because it reduces what type of heat loss?
Correct Answer: D
Rationale: The correct answer is D: evaporation. Skin-to-skin contact reduces evaporative heat loss by preventing the newborn's skin from losing heat through evaporation of amniotic fluid. This is effective in helping the baby maintain a stable body temperature. Radiation (A), convection (B), and conduction (C) are other types of heat loss that are not specifically addressed by skin-to-skin contact immediately after birth.
Question 5 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.
