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
Nonprescription medications can still have adverse effects on pregnancy and should be taken only with a healthcare provider's approval. This indicates a need for further teaching about safe medication use during pregnancy.
Choice B rationale
Reducing stress is beneficial during pregnancy and shows an understanding of healthy gestational changes. Stress management can positively impact maternal and fetal health.
Choice C rationale
Monitoring weight gain during pregnancy is important for maternal and fetal health. Appropriate weight gain supports healthy development and reduces the risk of complications.
Choice D rationale
Consulting with a doctor before using home remedies for nausea is a good practice. It ensures that the remedies are safe and appropriate for use during pregnancy.
Correct Answer is C
Explanation
Choice A rationale
2 units is insufficient to bring down a blood sugar level of 152 mg/dL adequately. According to the sliding scale, 2 units typically lower blood sugar by 50-60 mg/dL, which might not be enough for this level.
Choice B rationale
3 units might reduce blood sugar by approximately 75-90 mg/dL. However, this reduction may not be adequate to bring the blood sugar level within the target range, depending on individual response to insulin.
Choice C rationale
4 units of insulin are suitable for a blood sugar level of 152 mg/dL. Generally, 1 unit of insulin lowers blood sugar by 30-50 mg/dL. Administering 4 units should ideally lower the blood sugar level to the desired range.
Choice D rationale
5 units of insulin could result in an excessive drop in blood sugar levels. It could reduce the blood sugar level by 150-200 mg/dL, which might risk hypoglycemia, making it an unsuitable choice for a blood sugar level of 152 mg/dL.
