Down Syndrome
Down Syndrome ( 15 Questions)
A parent asks, "Why do individuals with Down syndrome experience cognitive impairment?" What should the nurse's response include?
The statement that "cognitive impairment is not related to genetics" is incorrect. Down syndrome is a genetic condition caused by the presence of an extra copy of chromosome 21, which directly impacts cognitive functioning.
The statement that "cognitive impairment is primarily due to a lack of intellectual stimulation" is also incorrect. While early intervention and intellectual stimulation can have a positive impact on individuals with Down syndrome, the condition itself is primarily caused by genetic factors.
The correct answer is choice C, "The impact on brain development and functioning is a key factor.”. Down syndrome results from an extra copy of chromosome 21, which leads to abnormalities in brain development and functioning. This genetic anomaly directly affects cognitive abilities. Individuals with Down syndrome typically have intellectual disabilities due to these genetic factors.
The statement that "cognitive impairment in Down syndrome is caused by a lack of social interaction" is not accurate. Social interaction can be beneficial for individuals with Down syndrome, but the primary cause of cognitive impairment in Down syndrome is genetic, not social interaction.
Choice A rationale:
The statement that "cognitive impairment is not related to genetics" is incorrect.
Down syndrome is a genetic condition caused by the presence of an extra copy of chromosome 21, which directly impacts cognitive functioning.
Choice B rationale:
The statement that "cognitive impairment is primarily due to a lack of intellectual stimulation" is also incorrect.
While early intervention and intellectual stimulation can have a positive impact on individuals with Down syndrome, the condition itself is primarily caused by genetic factors.
Choice C rationale:
The correct answer is choice C, "The impact on brain development and functioning is a key factor.”.
Down syndrome results from an extra copy of chromosome 21, which leads to abnormalities in brain development and functioning.
This genetic anomaly directly affects cognitive abilities.
Individuals with Down syndrome typically have intellectual disabilities due to these genetic factors.
Choice D rationale:
The statement that "cognitive impairment in Down syndrome is caused by a lack of social interaction" is not accurate.
Social interaction can be beneficial for individuals with Down syndrome, but the primary cause of cognitive impairment in Down syndrome is genetic, not social interaction.
