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 D
Explanation
Choice A reason: Cleansing wounds with povidone-iodine on cotton balls is not recommended because it can damage granulation tissue and delay healing. Cotton fibers may also remain in the wound, increasing infection risk.
Choice B reason: Administering analgesia prior to irrigation is appropriate for pain management but does not directly demonstrate correct irrigation technique. While important, it is not the best indicator of proper wound irrigation practice.
Choice C reason: Warming irrigation solution in the microwave is unsafe because it can cause uneven heating and burns. Solutions should be warmed to room temperature using safe methods, not microwaves.
Choice D reason: Irrigating from the cleanest to the most contaminated area is the correct technique. This prevents the spread of microorganisms from contaminated areas into clean tissue, promoting healing and reducing infection risk.
Correct Answer is D
Explanation
Choice A reason: Reporting that the client was provided with a breakfast tray at 0800 is not clinically significant information for a change-of-shift report. Shift reports should focus on pertinent clinical updates, ongoing concerns, and interventions that impact patient safety and care continuity. Meal times are routine and do not provide meaningful information for the incoming nurse.
Choice B reason: Nausea immediately after surgery is expected and would have occurred 36 hours earlier. This information is outdated and not relevant to the current status of the client. Change-of-shift reports should emphasize current or ongoing issues rather than resolved postoperative symptoms. Therefore, this option is not appropriate to include.
Choice C reason: Checking for peripheral IV blood return prior to administering antibiotics is a standard nursing practice and does not need to be included in a shift report unless there was a complication, such as infiltration or loss of IV access. Routine procedural details are not necessary unless they affect ongoing care. Thus, this option is not the best choice.
Choice D reason: Reporting that the client’s pain was relieved by position change is clinically relevant because it provides information about the client’s current pain management needs and effective interventions. Pain control is a critical aspect of postoperative care, and knowing what measures are effective helps ensure continuity of care. This is the correct answer because it directly impacts the incoming nurse’s ability to manage the client’s comfort and recovery.
