Olds Assessment of Newborn
What condition is due to poor peripheral circulation? 1. Acrocyanosis 2. Mottling 3. Harlequin sign 4. Jaundice
Answer: 1 Explanation: 1. Acrocyanosis is a bluish discoloration of the hands and feet that may be present in the first 24 hours after birth and is due to poor peripheral circulation, which results in vasomotor instability and capillary stasis, especially when the baby is exposed to cold.
The nurse assesses four newborns. Which of the following assessment findings would place a newborn at risk for developing physiologic jaundice? 1. Cephalohematoma 2. Mongolian spots 3. Telangiectatic nevi 4. Molding
Answer: 1 Explanation: 1. A cephalohematoma is a collection of blood resulting from ruptured blood vessels between the surface of a cranial bone and the periosteal membrane. They may be associated with physiologic jaundice, because there are extra red blood cells being destroyed within the cephalohematoma.
A nursing instructor is demonstrating an assessment on a newborn using the Ballard gestational assessment tool. The nurse explains that which of the following tests should be performed after the first hour of birth, when the newborn has had time to recover from the stress of birth? 1. Arm recoil 2. Square window sign 3. Scarf sign 4. Popliteal angle
Answer: 1 Explanation: 1. Arm recoil is slower in healthy but fatigued newborns after birth; therefore, arm recoil is best elicited after the first hour of birth, when the baby has had time to recover from the stress of birth.
The nurse wishes to demonstrate to a new family their infant's individuality. Which assessment tool would be most appropriate for the nurse to use? 1. Brazelton Neonatal Behavioral Assessment Scale 2. New Ballard Score 3. Dubowitz gestational age scale 4. Ortolani maneuver
Answer: 1 Explanation: 1. Brazelton Neonatal Behavioral Assessment Scale is an assessment tool that identifies the newborn's repertoire of behavioral responses to the environment and documents the newborn's neurologic adequacy and capabilities.

Answer: 1 Explanation: 1. Caput succedaneum is a localized, easily identifiable soft area of the scalp, generally resulting from a long and difficult labor or vacuum extraction.
Before the nurse begins to dry off the newborn after birth, which assessment finding should the nurse document to ensure an accurate gestational rating on the Ballard gestational assessment tool? 1. Amount and area of vernix coverage 2. Creases on the sole 3. Size of the areola 4. Body surface temperature
Answer: 1 Explanation: 1. Drying the baby after birth will disturb the vernix and potentially alter the gestational age criterion. The nurse should document the amount and areas of vernix coverage before drying the newborn.
The nurse suspects clubfoot in the newborn and assesses for the condition by doing which of the following? 1. Adducting the foot and listening for a click. 2. Moving the foot to midline and determining resistance. 3. Extending the foot and observing for pain. 4. Stimulating the sole of the foot.
Answer: 2 Explanation: 2. Clubfoot is suspected when the foot does not turn to a midline position or align readily.
The nurse is making an initial assessment of the newborn. Which of the following data would be considered normal? 1. Chest circumference 31.5 cm, head circumference 33.5 cm 2. Chest circumference 30 cm, head circumference 29 cm 3. Chest circumference 38 cm, head circumference 31.5 cm 4. Chest circumference 32.5 cm, head circumference 36 cm
Answer: 1 Explanation: 1. The average circumference of the head at birth is 32 to 37 cm. Average chest circumference ranges from 30 to 35 cm at birth. The circumference of the head is approximately 2 cm greater than the circumference of the chest at birth. Answer 1 is the only choice in which both the chest and head circumferences fall within the norm in terms of actual size and comparable size.
The nurse is teaching a group of new parents about their infants. The infants are all 4 weeks of age or younger. Which statement should the nurse include? 1. "Your baby will respond to you the most if you look directly into his eyes and talk to him." 2. "Each baby is different. Don't try to compare your infant's behavior with any other child's behavior." 3. "If the sound level around your baby is high, the baby will wake up and be fussy or cry." 4. "If your baby is a cuddler, it is because you rocked and talked to her during your pregnancy."
Answer: 1 Explanation: 1. The parents' visual (en face) and auditory (soft, continuous voice) presence stimulates their infant to orient to them.
The nurse assesses the newborn's ears to be parallel to the outer and inner canthus of the eye. The nurse documents this finding to be which of the following? 1. A normal position 2. A possible chromosomal abnormality 3. Facial paralysis 4. Prematurity
Answer: 1 Explanation: 1. The top of the ear (pinna) is parallel to the outer and inner canthus of the eye in the normal newborn.
The mother of a 16-week-old infant calls the clinic concerned because she cannot feel the posterior fontanelle on her infant. Which response by the nurse would be most appropriate? 1. "It is normal for the posterior fontanelle to close by 8 to 12 weeks after birth." 2. "Bring your infant to the clinic immediately." 3. "This is due to overriding of the cranial bones during labor." 4. "Your baby must be dehydrated."
Answer: 1 Explanation: 1. This is a normal finding at 16 weeks. The posterior fontanelle closes within 8 to 12 weeks.
The nurse is answering phone calls at the pediatric clinic. Which call should the nurse return first? 1. Mother of a 2-week-old infant who doesn't make eye contact when talked to 2. Father of a 1-week-old infant who sleeps through the noise of an older sibling 3. Father of a 6-day-old infant who responds more to mother's voice than to father's voice 4. Mother of a 3-week-old infant who has begun to suck on the fingers of the right hand
Answer: 1 Explanation: 1. This is an abnormal finding. Orientation to the environment is determined by an ability to respond to cues given by others and by a natural ability to fix on and to follow a visual object horizontally and vertically. Inability or lack of response may indicate visual or auditory problems.
) The nurse is preparing new parents for discharge with their newborn. The father asks the nurse why the baby's head is so pointed and puffy-looking. What is the best response by the nurse? 1. "His head is molded from fitting through the birth canal. It will become more round." 2. "We refer to that as 'cone head,' which is a temporary condition that goes away." 3. "It might mean that your baby sustained brain damage during birth, and could have delays." 4. "I think he looks just like you. Your head is much the same shape as your baby's."
Answer: 1 Explanation: 1. This statement is accurate and directly answers the father's question.
The student nurse attempts to take a newborn's vital signs, but the newborn is crying. What nursing action would be appropriate? 1. Place a gloved finger in the newborn's mouth. 2. Take the vital signs. 3. Wait until the newborn stops crying. 4. Place a hot water bottle in the isolette.
Answer: 1 Explanation: 1. Vital sign assessments are most accurate if the newborn is at rest, so measure pulse and respirations first if the baby is quiet. To soothe a crying baby, the nurse should place a moistened, unpowdered, gloved finger in the baby's mouth, and then complete the assessment while the baby suckles.
The nurse is cross-training maternal-child health unit nurses to provide home-based care for parents after discharge. Which statements indicate that additional teaching is required?

Answer: 3 Explanation: 3. Telangiectatic nevi (stork bites) appear as pale pink or red spots and are frequently found on the eyelids, nose, lower occipital bone, and nape of the neck.
The nurse is completing a newborn care class. The nurse knows that teaching has been effective if a new parent states which of the following? 1. "My baby might open her arms wide and pull her legs up to her tummy if she is passing gas." 2. "When I hold my baby upright with one of his feet on the floor, his feet will automatically remain still. 3. "When I put my finger in the palm of my daughter's hand, she will curl her fingers and hold on." 4. "I can get my baby to turn his head toward the right if I lift his right arm over his head."
Answer: 3 Explanation: 3. This is the Palmar grasp reflex and is elicited by stimulating the newborn's palm with a finger or object.
The nurse attempts to elicit the Moro reflex on a newborn, and assesses movement of the right arm only. Based on this finding, the nurse immediately assesses for which of the following? 1. Ortolani maneuver 2. Palmar grasping reflex 3. Clavicle 4. Tonic neck reflex
Answer: 3 Explanation: 3. When the Moro reflex is elicited, the newborn straightens arms and hands outward while the knees flex. Slowly the arms return to the chest, as in an embrace. If this response is not elicited, the nurse assesses the clavicle for a possible fracture.
A breastfeeding mother calls the pediatric clinic concerned about her 4-day-old baby's failure to gain weight. She states that the infant has lost several ounces since birth. The most appropriate response by the nurse would be which of the following? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. "Newborns tend to lose about 5% to 10% of their birth weight because of failure to give adequate supplements when breastfeeding." 2. "Newborns grow approximately 1 inch a month in the first 6 months. You will need to increase feedings to compensate for the growth spurt." 3. "Newborns have an initial weight loss in the first 3 to 4 days. Your baby's weight loss is normal." 4. "Newborns lose a lot of heat, so make sure you keep the baby's formula warm when you supplement the breast milk." 5. "Keep the baby from getting chilled or too warm because that can contribute to weight loss."
Answer: 3, 5 Explanation: 3. Newborns have a physiological weight loss of 5% to 10% in the first 3 or 4 days. 5. Weight loss in the newborn can be caused by temperature elevation or consistent chilling.
The parents of a newborn comment to the nurse that their infant seems to enjoy being held, and that holding the baby helps him calm down after crying. They ask the nurse why this happens.

"We are lucky to have a baby with a calm disposition." 3. "Our baby spends more time in the active alert phase." 4. "Cuddliness is a social behavior that some babies have."
Answer: 4 Explanation: 4. According to Brazelton Neonatal Behavioral Assessment Scale, cuddliness can be an indicator of personality.
The nurse is preparing to assess a newborn's neurological status. Which finding would require an immediate intervention? 1. At rest, the infant has partially flexed arms and the legs drawn up to the abdomen. 2. When the corner of the mouth is touched, the infant turns the head that direction. 3. The infant blinks when the exam light is turned on over the face and body. 4. The right arm is flaccid while the infant brings the left arm and fist upward to the head.
Answer: 4 Explanation: 4. Asymmetrical movement is not an expected finding, and could indicate neurological abnormality. Muscle tone should be symmetric and diminished muscle tone and flaccidity requires further evaluation.
A mother notices that her newborn is able to sleep without waking even when in the nursery with other newborns crying. The mother asks whether her baby might have a hearing problem because her father wears hearing aids. What should the nurse explain? 1. Newborn risk factors associated with potential hearing loss do not include a family history of hearing loss. 2. Newborns cannot hear, due to mucus accumulated in the middle ear, which takes several days to drain. 3. Newborns who are asleep do not respond to loud noises that are not accompanied by vibrations. 4. Newborns in a noisy nursery are able to habituate to the sounds, and might not react unless a sound is sudden or much louder.
Answer: 4 Explanation: 4. Habituation is the newborn's ability to diminish or shut down innate responses to specific repeated stimuli.
