A nurse is discussing various options for prenatal testing with a client who is at 7 weeks of gestation and has a family history of chromosomal abnormalities. Which of the following information should the nurse include?
A Coombs test determines cystic fibrosis.
Serum alpha-fetoprotein levels can assist in identifying neural tube defects.
A chorionic villi sampling will be performed during week 34 of the pregnancy.
Amniotic fluid screening identifies fetal bladder anomalies.
The Correct Answer is B
Choice A reason: The Coombs test is not used to determine cystic fibrosis. Instead, it is primarily used to detect antibodies that may cause hemolytic disease of the newborn, such as Rh incompatibility. Cystic fibrosis is diagnosed through genetic testing or sweat chloride testing, not through Coombs. Therefore, this option is scientifically inaccurate and misleading in the context of prenatal testing.
Choice B reason: Serum alpha-fetoprotein (AFP) testing is a maternal blood test performed during the second trimester, typically between 15–20 weeks of gestation. Elevated AFP levels can indicate neural tube defects such as spina bifida or anencephaly, while decreased levels may suggest chromosomal abnormalities like Down syndrome. This test is a standard part of prenatal screening and provides valuable information about fetal development. It is the correct answer because it directly relates to identifying congenital abnormalities early in pregnancy.
Choice C reason: Chorionic villus sampling (CVS) is indeed a test used to detect chromosomal abnormalities, but it is performed much earlier in pregnancy, usually between 10–13 weeks of gestation. It involves sampling placental tissue to analyze fetal chromosomes. Performing CVS at 34 weeks would be inappropriate and unsafe, as it is far beyond the recommended timeframe and would not provide useful diagnostic information at that stage. Thus, this option is incorrect due to the inaccurate timing stated.
Choice D reason: Amniotic fluid screening, also known as amniocentesis, is performed between 15–20 weeks of gestation. It involves sampling amniotic fluid to test for chromosomal abnormalities, genetic disorders, and certain infections. While it can detect conditions such as Down syndrome, trisomy 18, and neural tube defects, it is not specifically used to identify fetal bladder anomalies. Fetal bladder anomalies are typically diagnosed through ultrasound imaging rather than amniotic fluid analysis. Therefore, this choice is incorrect because it misrepresents the purpose of amniotic fluid screening.

Correct Answer is B
Explanation
Choice A reason: Echolalia refers to the repetition or echoing of words or phrases spoken by another person. It is commonly seen in conditions such as autism spectrum disorder or certain types of schizophrenia. In this case, the client is not repeating another person’s words but instead producing a string of unrelated words. Therefore, echolalia does not apply here.
Choice B reason: Word salad is characterized by a jumble of words and phrases that lack logical connection or meaning, making the speech incomprehensible. The client’s statement, “Run cats spin the rain throwing procedure mechanical paper lake,” is a classic example of word salad because it combines unrelated words into a nonsensical sequence. This reflects disorganized thought processes, which are a hallmark of schizophrenia. The nurse should document this as word salad to accurately capture the client’s speech disturbance.
Choice C reason: Neologisms are newly invented words or phrases that have meaning only to the individual using them. While neologisms are also common in schizophrenia, the client’s statement does not include invented words but rather real words strung together without logical meaning. Thus, neologisms are not the correct classification in this scenario.
Choice D reason: Clang association involves speech in which words are chosen based on their sound rather than their meaning, often producing rhyming or alliterative patterns. For example, a client might say, “Rain, train, pain, gain.” The client’s statement here does not demonstrate rhyming or sound-based connections but instead reflects disorganized, unrelated words. Therefore, clang association is not the correct documentation.
Correct Answer is B
Explanation
Choice A reason: Fluticasone is an inhaled corticosteroid used for long-term control of asthma. It is not required to be administered before other inhaled medications; bronchodilators are usually given first to open airways before corticosteroids.
Choice B reason: Rinsing the mouth and gargling after each use is correct because inhaled corticosteroids can cause oral candidiasis (thrush). Rinsing removes residual medication and reduces this risk.
Choice C reason: Fluticasone is not used as needed; it is a maintenance medication taken regularly to prevent inflammation. Rescue inhalers such as albuterol are used for acute symptom control.
Choice D reason: Growth may be slowed, not accelerated, in children using inhaled corticosteroids. Monitoring growth is important during long-term therapy.
