A newborn is delivered by vaginal birth at 40 weeks of gestation.
Which of the following findings should the nurse report to the provider?
Heart rate 160/min and respirations 40/min.
Head circumference 40cm and chest circumference 32cm.
Positive Babinski reflex and negative Ortolani's sign.
Acrocyanosis and caput succedaneum.
The Correct Answer is B
Choice A rationale
A newborn's heart rate typically ranges from 120 to 160 beats per minute, and respirations are normally between 30 and 60 breaths per minute. A heart rate of 160/min and respirations of 40/min fall within these normal physiological ranges for a newborn, indicating adequate cardiovascular and respiratory adaptation to extrauterine life.
Choice B rationale
The average head circumference for a full-term newborn ranges from 33 to 35 cm, and the chest circumference is typically 2 to 3 cm less than the head circumference. A head circumference of 40 cm is significantly larger than the normal range, and a chest circumference of 32 cm suggests an abnormal head-to-chest ratio. These measurements could indicate hydrocephalus or other developmental anomalies and warrant immediate reporting to the provider for further assessment.
Choice C rationale
A positive Babinski reflex, characterized by dorsiflexion of the big toe and fanning of the other toes, is a normal neurological finding in newborns and infants up to 12-24 months of age, indicating an immature corticospinal tract. A negative Ortolani's sign indicates the absence of hip dislocation or dysplasia, which is a normal and desired finding, reflecting stable hip joints.
Choice D rationale
Acrocyanosis, which is the bluish discoloration of the hands and feet, is a common and normal finding in newborns during the first 24 to 48 hours after birth due to immature peripheral circulation. Caput succedaneum, a localized swelling of the scalp that crosses suture lines, is also a common and benign finding resulting from pressure during vaginal birth, typically resolving spontaneously within a few days.

Correct Answer is ["B","D","E"]
Explanation
Choice A rationale
While hearing loss can occur in some individuals with spina bifida due to associated anomalies or complications like meningitis, it is not as universally expected as other neurological impairments. The primary impact of hydrocephalus and neurological damage often manifests in areas directly related to brain development and function, making hearing loss a less common direct consequence.
Choice B rationale
Neurological damage associated with hydrocephalus and spina bifida frequently affects brain regions responsible for speech production and language processing. This can lead to various speech problems, including dysarthria or apraxia of speech, due to impaired motor control or cognitive deficits impacting linguistic expression and comprehension.
Choice C rationale
Frequent seizures are a potential complication of hydrocephalus and neurological damage due to abnormal electrical activity in the brain caused by structural anomalies or increased intracranial pressure. However, while possible, they are not as universally present in all cases as other common motor and cognitive impairments, making them a less frequent expectation.
Choice D rationale
Spina bifida often involves malformations of the spinal cord, directly impacting nerve function to the lower extremities. Hydrocephalus, by causing increased intracranial pressure and brain damage, can further impair motor control pathways. This combination frequently leads to motor deficits, resulting in varying degrees of difficulty walking or complete paralysis.
Choice E rationale
Hydrocephalus, especially when associated with neurological damage, can significantly impair cognitive development due to increased intracranial pressure and damage to brain tissue. This can manifest as delays in various cognitive domains, including learning, memory, problem-solving, and executive functions, impacting overall intellectual functioning.
Correct Answer is ["A","C"]
Explanation
Choice A rationale
Detergent pods are highly concentrated and can cause severe chemical burns to the esophagus and respiratory tract if ingested. Their bright colors and soft, squeezable nature can attract young children, making them a significant aspiration and poisoning risk due to their caustic properties. Normal esophageal tissue is delicate and easily damaged by corrosives.
Choice B rationale
Television remote controls, while a common household item, are typically too large and irregularly shaped to be easily aspirated into a toddler's airway. The primary concern with remote controls is choking on small, removable parts like batteries, not aspiration of the entire object into the trachea. Normal airway diameter in toddlers is small.
Choice C rationale
A tennis ball, due to its size and spherical shape, can perfectly occlude a toddler's airway, leading to complete obstruction and potential asphyxiation. Its smooth surface makes it difficult to dislodge once aspirated, posing a significant and immediate life-threatening choking hazard for young children. Normal tracheal lumen can be fully occluded by objects of similar diameter.
Choice D rationale
Hairbrushes are generally too large and awkwardly shaped to be aspirated by a toddler. While bristles or small decorative elements could potentially break off and be ingested, the primary concern with a hairbrush itself is not airway obstruction through aspiration of the entire object. Normal pharyngeal reflexes would typically prevent aspiration of such large objects. .
