A nurse is reinforcing teaching about the purpose of quadruple screening for a client who is at 16 weeks of gestation. Which of the following statements should the nurse make?
"This test identifies indicators for birth defects."
"This test determines the sex of the fetus."
"This test screens for gestational diabetes,"
"This test diagnoses fetal infection."
The Correct Answer is A
A. "This test identifies indicators for birth defects.": The quadruple screen (quad screen) measures four maternal serum markers, alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol, and inhibin-A, to assess the risk of fetal neural tube defects and chromosomal abnormalities such as Down syndrome.
B. "This test determines the sex of the fetus.": The quadruple screen does not determine fetal sex. Fetal sex can be identified through ultrasound or genetic testing, but the serum markers in the quad screen are not used for this purpose.
C. "This test screens for gestational diabetes.": Gestational diabetes is screened with a glucose challenge test or oral glucose tolerance test, not the quadruple screen. The quad screen focuses on markers related to fetal development and chromosomal anomalies, not maternal glucose metabolism.
D. "This test diagnoses fetal infection.": The quad screen does not detect infections in the fetus. Screening for fetal infections involves serologic testing, amniocentesis, or other targeted assessments depending on the suspected pathogen.

Correct Answer is C
Explanation
A. Accountability: Accountability refers to the nurse being responsible for their actions, decisions, and the outcomes of care provided. While important, simply explaining the purpose of a medication does not directly demonstrate accountability.
B. Autonomy: Autonomy involves supporting a client’s right to make informed decisions about their own care. The nurse’s explanation provides information but does not itself constitute enabling the client’s decision-making; additional discussion and consent would be required to demonstrate autonomy.
C. Veracity: Veracity is the ethical principle of truthfulness. By accurately explaining that furosemide is a diuretic that removes excess fluid, the nurse is providing truthful, clear information, allowing the client to understand their treatment and fostering trust.
D. Justice: Justice involves treating clients fairly and equitably, ensuring equal access to care and resources. Explaining the purpose of a prescribed medication is not an example of justice, as it pertains to truthful communication rather than fairness or resource allocation.
Correct Answer is A
Explanation
A. Poor feeding: Newborns experiencing neonatal abstinence syndrome (NAS) often have neurologic irritability and gastrointestinal dysfunction caused by withdrawal from in utero exposure to opioids or other substances. Poor feeding, along with vomiting, diarrhea, and excessive sucking, is a common manifestation.
B. Weak cry: Infants with NAS typically have a high-pitched, shrill, or incessant cry due to central nervous system hyperactivity. A weak or soft cry is not characteristic and may suggest other neurologic conditions rather than withdrawal.
C. Hypotonia: NAS usually presents with hypertonia, jitteriness, and tremors. Hypotonia is not a typical finding; decreased muscle tone may indicate a different neurologic or metabolic disorder.
D. Absent Moro reflex: The Moro reflex is generally intact or exaggerated in infants with NAS because of increased neuromuscular irritability. An absent reflex is more consistent with severe neurologic impairment rather than substance withdrawal.
