N406 Exam 3 Cognitive & Sensory Impairment

A nurse is preparing to perform a newborn assessment on an infant suspected of having Down Syndrome (Trisomy 21). The nurse knows that which maternal factor represents the most significant risk factor for this condition?

Maternal age greater than 35 years.

The nurse is admitting a 4-year-old child with Down Syndrome to the pediatric unit for an acute respiratory illness. When planning the child's daily care and schedule, which strategy should the nurse implement to best support the child's behavioral needs?

Keep the child on their home routine and maintain consistency as much as possible.

A nurse is performing a physical assessment on a newborn newly diagnosed with Down Syndrome. Which head and neck manifestations should the nurse expect to find documented?

Inner epicanthal folds, a wide and flat nasal bridge, a protruding tongue, and a short, broad neck.

The nurse is completing an extremity assessment on an infant with Trisomy 21. Which physical characteristics are consistent with this diagnosis?

Broad, short hands with stubby fingers.

A nurse is preparing a discharge teaching plan for the parents of a 10-month-old infant with Down Syndrome. The nurse knows that during the first year of life, which medical evaluation is a priority to detect a common associated anomaly?

A full cardiac workup to detect any cardiac anomalies or heart malformations.

The nurse is assessing a 2-month-old infant with Down Syndrome during a clinic visit. The mother reports that the infant has an uncoordinated suck and frequently spits up during feedings. The nurse knows this is related to which aspect of the child’s condition?

Gastrointestinal disorders and a difficulty sucking and feeding associated with hypotonia and a protruding tongue.

A nurse is reviewing the medical records of several pediatric clients with Down Syndrome. Which chronic medical conditions are recognized as being associated with this genetic disorder?

Hearing and vision impairments, thyroid disease, obstructive sleep apnea, sensitive skin, and seizures.

The nurse is caring for a 3-year-old child with Down Syndrome. The parents ask what behavioral and development points the healthcare team monitors during this toddler stage. Which focal points match the blueprint guidelines?

Monitoring sleep patterns and behavior.

A nurse is teaching a parent group about Fragile X Syndrome. Which description accurately identifies the genetic inheritance pattern of this disorder?

A sex-linked, X-linked dominant inheritance where the gene is located on the X chromosome.

The nurse is assessing a child newly diagnosed with Fragile X Syndrome. Which cognitive and life-span characteristics are typical of this genetic condition?

Significant cognitive and learning disabilities alongside a normal life span.

A nurse is coordinating care for a school-aged child with Fragile X Syndrome. Because there is no genetic cure for the underlying mutation, the nurse knows that interventions must target symptoms using which multi-disciplinary approach?

Medications to improve cognitive, emotional, and behavioral impairments, alongside special education and vocational programs.

The parents of a child with Fragile X Syndrome are planning to have more children and ask the nurse if genetic counseling is necessary. Which rationale best supports the nurse’s recommendation for genetic counseling?

Carrier mothers transmit the disease because the gene is located on the X chromosome, and a full mutation can be passed on.

A nurse is assessing a toddler with Down Syndrome and notes low muscle tone during moving and positioning. Which clinical term should the nurse use to document this finding?

Hypotonia

A nurse is discussing supportive care with the family of a child with Down Syndrome. Which action should the nurse encourage to help the family manage resources effectively?

Provide quick identification of resources, assist with accepting the diagnosis, and encourage participation.

The nurse is reviewing a genetic profile for an individual with Fragile X Syndrome. The nurse notes that females can be carriers of either a partial or full mutation because they possess an XX genotype, whereas males (XY) typically exhibit a full mutation. This description defines which component of the disease?

The X-linked sex-linked inheritance pattern of Fragile X Syndrome.
