Down Syndrome Quiz
Questions: 16 · 10 minutes
1. A newborn has physical features that suggest Down syndrome. What is generally used to confirm the diagnosis after birth?
A developmental questionnaire completed by the parents
Chromosome analysis, such as a karyotype, using a blood sample
A physical examination alone
A repeat prenatal screening calculation
2. During pregnancy, which procedure can provide cells for a diagnostic chromosome analysis rather than only estimating chance?
Amniocentesis followed by chromosome analysis
A detailed ultrasound examination
Cell-free DNA screening from maternal blood
A routine parental carrier screen
3. A student with Down syndrome joins a general-education classroom. Which statement best reflects an effective approach?
Expect the same learning pace without any adjustments
Use individualized accommodations and meaningful inclusion based on the student's strengths and needs
Assume a separate classroom is always required
Focus on social participation while excluding academic goals
4. How do most cases of Down syndrome arise?
They are caused by something a parent did during pregnancy
They are always inherited from a parent with the condition
They develop when an infant is exposed to a common infection
They usually result from a chance error in chromosome separation during cell division
5. What is the usual genetic basis of Down syndrome?
A mutation in a single chromosome 21 gene in every case
A missing copy of chromosome 21
An extra copy of the X chromosome
An extra full or partial copy of chromosome 21
6. An adult with Down syndrome takes longer to answer a question. What is the most respectful first response?
Direct the question to a companion instead
Replace the question with one intended for a young child
Repeat the question more loudly immediately
Allow time to respond and communicate directly in an age-appropriate way
7. A child with Down syndrome currently appears healthy. Which healthcare approach is most appropriate?
Use only the routine care schedule because Down syndrome has no health associations
Arrange treatment for every condition associated with Down syndrome, even without evidence
Use regular, individualized health supervision because some conditions are more common but not inevitable
Delay preventive checks until symptoms interfere with daily activities
8. What does mosaic Down syndrome mean?
Chromosome 21 is absent from some cells
Every cell has three separate full copies of chromosome 21
Some cells have an extra copy of chromosome 21 while others have the usual number
Chromosome 21 material is present only in reproductive cells
9. What occurs in translocation Down syndrome?
A section of chromosome 21 disappears after birth
Extra chromosome 21 material is attached to another chromosome
The number of chromosome 21 copies changes repeatedly throughout life
All chromosomes are copied one additional time
10. A toddler with Down syndrome is developing communication and motor skills. Which support is commonly appropriate when tailored to the child?
Waiting until school age before assessing development
Using one standard therapy plan for every child with Down syndrome
Early-intervention services such as speech, physical, or occupational therapy
Replacing educational support with medical testing alone
11. Someone recognizes several traits associated with Down syndrome in themselves or a family member after taking an online quiz. What should they conclude?
Matching several traits confirms Down syndrome
Traits alone are not diagnostic; questions should be discussed with a qualified clinician or genetic counselor
Absence of one commonly described trait rules it out
A high quiz score can replace chromosome testing
12. A prenatal screening report indicates an increased chance of Down syndrome. What is the most accurate interpretation?
The result estimates chance and may be followed by counseling or diagnostic testing
The result confirms the fetus does not have another chromosome condition
The screening result is equivalent to a diagnostic chromosome analysis
The fetus definitely has Down syndrome
13. Which statement accurately describes the relationship between maternal age and Down syndrome?
Its likelihood increases with maternal age, but it can occur at any maternal age
Maternal age has no relationship to its likelihood
It occurs only in pregnancies involving people over age 35
Younger maternal age is the primary genetic cause
14. A clinician notes hypotonia in a baby with Down syndrome. What does hypotonia refer to?
Reduced ability to hear quiet sounds
An unusually low number of muscle fibers
Lower muscle tone
A permanent loss of voluntary movement
15. Which statement best describes how Down syndrome affects different people?
Characteristics and support needs vary considerably from person to person
Physical traits are consistent, but learning profiles are identical
Everyone has the same medical conditions and support needs
Differences appear only during adulthood
16. Which wording is generally respectful when referring to someone who has Down syndrome?
A Down syndrome sufferer
A Down's person
A person defined by a chromosomal disorder
A person with Down syndrome
