A nursing student is helping the nursery nurse with morning vital signs. A baby born 10 hours ago via cesarean section is found to have moist lung sounds. Which is the best interpretation of this information? a. This is an emergency situation. b. The neonate must have aspirated surfactant. c. If this baby was born vaginally, it could indicate a pneumothorax. d. The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth. ANS: D The condition will resolve itself within a few hours. For this common condition of newborns, surfactant acts to keep the expanded alveoli partially open between respirations. In vaginal births, absorption of remaining lung fluid is accelerated by the process of labor and birth. Remaining lung fluid will move into interstitial spaces and be absorbed by the circulatory and lymphatic systems. This is a common condition for infants delivered by cesarean section. Surfactant is produced by the lungs, so aspiration is not a concern. It is common to have some fluid left in the lungs; this will be absorbed within a few hours. contact: [email protected] 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 2/20 PTS: 1 DIF: Cognitive Level: Analysis REF: 368 OBJ: Nursing Process Step: Assessment MSC: Client Needs: Health Promotion and Maintenance 2. Which organs are nonfunctional during fetal life? a. Eyes and ears b. Lungs and liver c. Kidneys and adrenals d. Gastrointestinal system ANS: B Most of the fetal blood flow bypasses the nonfunctional lungs and liver. Near term, the eyes are open and the fetus can hear. Kidneys and adrenals function during fetal life. The fetus continuously swallows amniotic fluid, which is filtered through the kidneys. The gastrointestinal system functions during fetal life.

Which method of heat loss may occur if a newborn is placed on a cold scale or touched with cold hands? a. Radiation b. Conduction c. Convection d. Evaporation 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 3/20 ANS: B Conduction occurs when the infant comes in contact with cold objects. Radiation is the transfer of heat to a cooler object that is not in direct contact with the infant. Convection occurs when heat is transferred to the air surrounding the infant. Evaporation can occur during birth or bathing as a result of wet linens or clothes, or insensible heat loss. PTS: 1 DIF: Cognitive Level: Understanding REF: 372 OBJ: Nursing Process Step: Implementation MSC: Client Needs: Physiologic Integrity 4. How can nurses prevent evaporative heat loss in the newborn? a. Placing the baby away from the outside wall and the windows b. Keeping the baby out of drafts and away from air conditioners c. Drying the baby after birth and wrapping the baby in a dry blanket d. Warming the stethoscope and nurse’s hands before touching the baby ANS: C Wet linens or wet clothes can cause heat loss by evaporation. If the heat loss is caused by placing the baby near cold surfaces or equipment, it is termed a radiation heat loss. Heat loss by convection occurs when drafts come from open doors and air currents created by people moving around. Conduction heat loss occurs when the baby comes into contact with cold objects or surfaces.

The nurse is explaining how a newly delivered baby initiates respirations. Which statement explains this process? a. Drying off the infant b. Chemical, thermal, and mechanical factors c. An increase in the PO and a decrease in the PCO d. The continued functioning of the foramen ovale ANS: B A variety of these factors are responsible for initiation of respirations. Tactile stimuli aid in initiating respirations but are not the main cause. The PO decreases at birth and the PCO increases. The foramen ovale closes at birth. PTS: 1 DIF: Cognitive Level: Application REF: 369 OBJ: Nursing Process Step: Implementation MSC: Client Needs: Physiologic Integrity 6. During fetal circulation the pressure is greatest in the: a. left atrium. b. right atrium. c. hepatic system. 2 2 2 2 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 5/20 d. pulmonary veins. ANS: B Pressure in the fetal circulation is greatest in the right atrium, which allows right-to-left shunting that aids in bypassing the lungs during intrauterine life. The pressure increases in the left atrium after birth and will close the foramen ovale. The liver does not filter the blood during fetal life until the end. It is functioning by birth. Blood bypasses the pulmonary vein during fetal life. PTS: 1 DIF: Cognitive Level: Remembering REF: 370 OBJ: Nursing Process Step: Assessment MSC: Client Needs: Health Promotion and Maintenance 7. Parents ask the nurse, “What makes the opening between the baby’s atriums close at birth?” The nurse’s response is that cardiovascular changes that cause the foramen ovale to close at birth are a direct result of: a. changes in the hepatic blood flow. b. increased pressure in the left atrium. c. increased pressure in the right atrium. d. decreased blood flow to the left ventricle. ANS: B With the increase in the blood flow to the left atrium from the lungs, the pressure is increased, and the foramen ovale is functionally closed. The hepatic blood flow changes, but that is not the reason for the closure of the foramen ovale. The pressure in the right atrium decreases at birth. It is higher during fetal life. Blood flow increases to the left ventricle after birth.

The infant’s heat loss immediately at birth is predominantly from: a. radiation. b. conduction. c. convection. d. evaporation. ANS: D Because the infant is wet with amniotic fluid and blood, heat loss by evaporation occurs quickly. Radiation occurs with the transfer of heat to a cooler object that is not in direct contact with the infant. Conduction occurs when the infant comes into contact with a cold surface. The crib should be preheated to prevent this from occurring. Convection occurs when heat is transferred to the air surrounding the infant.

The nurse is explaining the risk of hypothermia in the newborn to a group of nursing students. Which should the nurse include as an explanation of hypothermia in the newborn? a. Newborns shiver to generate heat. b. Newborns have decreased oxygen demands. c. Newborns have increased glucose demands. d. Newborns have a decreased metabolic rate. 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 7/20 ANS: C In hypothermia, the basal metabolic rate (BMR) is increased in an attempt to compensate, thus requiring more glucose. Shivering is not an effective method of heat production for newborns. Oxygen demands increase with hypothermia. The metabolic rate increases with hypothermia. PTS: 1 DIF: Cognitive Level: Application REF: 373 OBJ: Nursing Process Step: Implementation MSC: Client Needs: Physiologic Integrity 10. Which infant has the lowest risk of developing high levels of bilirubin? a. The infant who developed a cephalohematoma b. The infant who was bruised during a difficult birth c. The infant who uses brown fat to maintain temperature d. The infant who is breastfed during the first hour of life ANS: D The infant who is fed early will be less likely to retain meconium and resorb bilirubin from the intestines back into the circulation. Cephalohematomas will release bilirubin into the system as the red blood cells die off. Bruising will release more bilirubin into the system. Brown fat is normally used to produce heat in the newborn.

The nurse is preparing to administer a vitamin K injection to the infant shortly after birth. Which is important to understand about vitamin K? a. It is necessary for the production of platelets. b. It is important for the production of red blood cells. c. It is not initially synthesized because of a sterile bowel at birth. d. It is responsible for the breakdown of bilirubin and the prevention of jaundice. ANS: C The bowel is initially sterile in the newborn, and vitamin K cannot be synthesized until food is introduced into the bowel. The platelet count in term newborns is near adult levels. Vitamin K is necessary to activate prothrombin and other clotting factors. Vitamin K is important for blood clotting. Vitamin K is necessary to activate the clotting factors.

A meconium stool can be differentiated from a transitional stool in the newborn because the meconium stool is: a. seen at 3 days of age. b. the residue of a milk curd. c. passed in the first 24 hours of life. 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 9/20 d. lighter in color and looser in consistency. ANS: C Meconium should be passed in the first 24 hours of life. Meconium stool is the first stool of the newborn. Meconium stool is made up of matter in the intestines during intrauterine life. Meconium is dark in color and sticky. PTS: 1 DIF: Cognitive Level: Understanding REF: 376 OBJ: Nursing Process Step: Assessment MSC: Client Needs: Health Promotion and Maintenance 13. Which is the most likely cause of regurgitation when a newborn is fed? a. The gastrocolic reflex b. A relaxed cardiac sphincter c. An underdeveloped pyloric sphincter d. Placing the infant in a prone position following a feeding ANS: B The underlying cause of newborn regurgitation is a relaxed cardiac sphincter. The gastrocolic reflex increases intestinal peristalsis after the stomach fills. The pyloric sphincter goes from the stomach to the intestines. The infant should be placed in a supine position. PTS: 1 DIF: Cognitive Level: Understanding REF: 375 OBJ: Nursing Process Step: Implementation MSC: Client Needs: Health Promotion and Maintenance 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 10/20 14. The process in which bilirubin is changed from a fat-soluble product to a water-soluble product is known as: a. albumin binding. b. enterohepatic circuit. c. conjugation of bilirubin. d. deconjugation of bilirubin. ANS: C Conjugation of bilirubin is the process of changing the bilirubin from a fat-soluble to a water-soluble product. Albumin binding attaches something to a protein molecule. Enterohepatic circuit is the route whereby part of the bile produced by the liver enters the intestine, is resorbed by the liver, and then is recycled into the intestine. Unconjugated bilirubin is fat-soluble. PTS: 1 DIF: Cognitive Level: Understanding REF: 376 OBJ: Nursing Process Step: Assessment MSC: Client Needs: Physiologic Integrity 15. A newborn is admitted to the newborn nursery with hypothermia. Which complication should the nurse monitor related to hypothermia in the newborn? a. Hyperglycemia b. Metabolic acidosis c. Respiratory acidosis d. Vasodilation of peripheral blood vessels 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 11/20 ANS: B Cold stress can cause a significant rise in oxygen demands. Metabolism of glucose in the presence of insufficient oxygen causes increased production of acids. Metabolism of brown fat also releases fatty acids. The result can be metabolic acidosis, which can be a life-threatening condition. Cold stress causes hypoglycemia because glucose is being metabolized. Cold stress does not cause respiratory acidosis. As the infant’s body attempts to conserve heat, vasoconstriction, not vasodilation, of the peripheral blood vessels occurs to reduce heat loss from the skin surface. PTS: 1 DIF: Cognitive Level: Analysis REF: 374 OBJ: Nursing Process Step: Evaluation MSC: Client Needs: Physiologic Integrity 16. Which action by the nurse can cause hyperthermia in the newborn? a. Placing a cap on the newborn b. Wrapping the newborn in a warm blanket c. Placing the newborn in a skin to skin position with the mother d. Placing the newborn in the radiant warmer without attaching the skin probe ANS: D Newborns may be overheated by poorly regulated equipment designed to keep them warm. When radiant warmers, warming lights, or warmed incubators are used, the temperature mechanism must be set to vary the heat according to the infant’s skin temperature; this prevents too much or too little heat. Alarms to signal that the infant’s temperature is too high or too low should be functioning properly. If the skin probe is not used, the alarms will not function properly. Putting a hat on the newborn, wrapping the newborn in a warm blanket, or placing the newborn skin to skin with the mother will not cause hyperthermia. PTS: 1 DIF: Cognitive Level: Application REF: 374 OBJ: Nursing Process Step: Implementation 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 12/20 MSC: Client Needs: Safe and Effective Care Environment 17. A multiparous patient arrives to the labor unit and urgently states, “The baby is coming RIGHT NOW!” The nurse assists the patient into a comfortable position and delivers the infant. To prevent infant heat loss from conduction, what is the priority nursing action? a. Dry the baby off. b. Turn up the temperature in the patient’s room. c. Pour warmed water over the baby immediately after birth. d. Place the baby on the patient’s abdomen after the cord is cut. ANS: D Movement of heat away from the body occurs when newborns have direct contact with objects that are cooler than their skin. Placing infants on cold surfaces or touching them with cool objects causes this type of heat loss. The reverse is also true; contact with warm objects increases body heat by conduction. Warming objects that will touch the infant or placing the unclothed infant against the mother’s skin (skin to skin) helps prevent conductive heat loss. Drying the baby off helps prevent heat loss through evaporation. Adjusting the temperature in the patient’s room helps with heat loss through convection. Pouring warm water over a baby occurs with the first bath, which is conducted after the baby’s temperature has stabilized. Pouring warm water over the baby prior to that time will increase heat loss through evaporation.

The nurse is planning to conduct the initial assessment of a full-term newborn. Included in the plan is providing a neutral thermal environment. To accomplish this plan, what is the desired environmental temperature to conduct the assessment? 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 13/20 a. 24° to 27° C (75.2° to 80.6° F) b. 28° to 31.5° C (82.4° to 88.7° F) c. 32° to 33.5° C (89.6° to 92.3° F) d. 34° to 37.5° C (93.2° to 99.5° F) ANS: C A neutral thermal environment is one in which the infant can maintain a stable body temperature with minimal oxygen need and without an increase in metabolic rate. The range of environmental temperature that allows this stability is called the thermoneutral zone. In healthy, unclothed, full-term newborns, an environmental temperature of 32° to 33.5° C (89.6° to 92.3° F) provides a thermoneutral zone. When the infant is dressed, the thermoneutral range is 24° to 27° C (75.2° to 80.6° F).

An infant at 36 weeks’ gestation was just delivered; included in the protocol for a preterm infant is an initial blood glucose assessment. The nurse obtains the blood and the reading is 58 mg/dL. What is the priority nursing action based on this reading? a. Document the finding in the newborn’s chart. b. Double-wrap the newborn under a warming unit. c. Feed the newborn a 10% dextrose solution. d. Notify the neonatal intensive care unit (NICU) of the pending admission. 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 14/20 ANS: A In the term infant, glucose levels should be 40 to 60 mg/dL on the first day and 50 to 90 mg/dL thereafter. There is no general consensus about the level of blood glucose that defines hypoglycemia, but a level below 40 to 45 mg/dL in the term infant is often used. If an infant is placed in a warming unit, the skin needs to be exposed. Because the glucose level is normal, no supplemental feeding is necessary. Dextrose solution is only administered when the glucose levels are very low. There is no information in the stem indicating the need for admission to the NICU.

Small-for-gestational-age newborn d. 9/10/2020 Chapter 19: Normal Newborn: Processes of Adaptation | Nursing Test Banks https://boostgrade.info/chapter-19-normal-newborn-processes-of-adaptation/ 18/20 Large-for-gestational-age newborn e. Term newborn born by cesarean birth ANS: A, C, D Many newborns are at increased risk for hypoglycemia. In the preterm, late preterm (born between 34 weeks and 36 6/7 weeks of gestation), and small-for-gestational-age infant, adequate stores of glycogen or even fat for metabolism may not have accumulated. Stores may be used up before birth in the post-term infant because of poor intrauterine nourishment from a deteriorating placenta. Large-for-gestational-age infants and those with diabetic mothers may produce excessive insulin that consumes available glucose quickly. The newborn born at 38 weeks and the newborn born by cesarean at term have lower risk for hypoglycemia.
