A client's cell-free DNA screening is positive for trisomy 21. Which statement by the nurse is accurate?

  1. "This result confirms that the baby has Down syndrome."
  2. "No further testing is needed because this screening is diagnostic."
  3. "Further testing such as amniocentesis is needed to confirm a diagnosis."
  4. "This result is not valid until you repeat it after delivery."
Show answer

Correct answer: "Further testing such as amniocentesis is needed to confirm a diagnosis."

A positive cfDNA screen means the fetus is at risk. Diagnostic tests such as CVS or amniocentesis confirm the diagnosis.
