A nurse is reinforcing teaching with a newly licensed nurse about embryonic nutrition.
Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
Prior to the development of the placenta, the amnion provides nutrients.
The chorion supports development of the embryo.
The allantois will work to provide nutrients prior to the development of the placenta.
The yolk sac provides nutrients to the developing embryo.
The Correct Answer is D
Choice A rationale
The amnion is a membrane that encloses the amniotic fluid but does not provide nutrients to the embryo.
Choice B rationale
The chorion forms part of the placenta and contributes to nutrient and gas exchange once the placenta develops, but it does not provide nutrients before the placenta forms.
Choice C rationale
The allantois is involved in early fluid exchange and waste management but does not provide nutrients before the placenta forms.
Choice D rationale
The yolk sac provides nutrients to the developing embryo before the placenta is fully functional, supporting early embryonic development.

Correct Answer is D
Explanation
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 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.
