A nurse is reinforcing teaching to a group of clients about genetic disorders.
Which of the following statements should the nurse include in the education reinforcement?
Recessive disorders will manifest in every subsequent generation.
Single gene disorders are collectively prevalent and detectable.
Genetic disorders are always passed down from one's biological predecessors.
Single gene disorders can be traced through genetic lineage.
The Correct Answer is D
Choice A rationale
Recessive disorders do not manifest in every subsequent generation. They appear only when an individual inherits two copies of the recessive gene, one from each parent, making them less frequent in the population.
Choice B rationale
Single gene disorders are not collectively prevalent; they are relatively rare. They are caused by mutations in a single gene and are not always detectable without specific genetic testing.
Choice C rationale
Genetic disorders are not always passed down from one's biological predecessors. Some genetic disorders arise from new mutations that occur during the formation of eggs or sperm, or early in embryonic development.
Choice D rationale
Single gene disorders can indeed be traced through genetic lineage. By analyzing family histories and genetic testing, these disorders can often be identified and tracked across generations.

Correct Answer is A
Explanation
Choice A rationale
Painless, bright red vaginal bleeding at 36 weeks gestation is a classic sign of placenta previa, where the placenta is abnormally implanted in the lower uterine segment, covering the cervix, and causing bleeding without pain.
Choice B rationale
Threatened abortion is characterized by vaginal bleeding before 20 weeks of gestation with or without abdominal pain. At 36 weeks, the term would be inappropriate, and the symptoms do not match.
Choice C rationale
Abruptio placentae involves painful vaginal bleeding due to premature placental separation. The presence of pain differentiates it from placenta previa.
Choice D rationale
Preterm labor may present with contractions, cervical changes, and possible bleeding, but the key feature distinguishing it from placenta previa is the presence of uterine contractions and pain, which are absent in this scenario.
Correct Answer is A
Explanation
Choice A rationale
Hypothyroidism during pregnancy is associated with increased risks of metabolic disorders, including lipid and glucose metabolism disorders, which can affect both the mother and fetus.
Choice B rationale
hCG levels do not typically plateau in the first trimester; they continue to rise and peak around the 10th week of pregnancy before starting to decline.
Choice C rationale
Thyroid replacement dosing usually needs adjustment during pregnancy to meet the increased thyroid hormone requirements due to physiological changes and fetal development needs.
Choice D rationale
Antenatal fetal surveillance is generally required in the third trimester for hypothyroid pregnant clients to monitor fetal well-being, not during the first trimester.
