1. Rubella, also called German measles, is a viral infection passed from the mother to the fetus that can cause birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo.
- A. Rubella
- B. Syphilis
- C. Cystic fibrosis
- D. Phenylketonuria
Correct answer: A
Rationale: Rubella, also known as German measles, is a viral infection that can lead to severe birth defects when contracted by a mother during pregnancy. Rubella is the correct answer because it is specifically associated with causing birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo. Syphilis (Choice B) can be passed from mother to fetus but does not cause the mentioned birth defects associated with Rubella. Cystic fibrosis (Choice C) and Phenylketonuria (Choice D) are genetic conditions and not infections transmitted from mother to fetus, making them incorrect choices in this context.
2. Which of the following most accurately describes the function of genes?
- A. They regulate the development of traits.
- B. They prevent foreign particles from entering the body.
- C. They work together with lutein to influence development.
- D. They transfer oxygen from the bloodstream to other parts of the body.
Correct answer: A
Rationale: The correct answer is A: 'They regulate the development of traits.' Genes play a crucial role in regulating the development of traits by encoding proteins that control various bodily functions and characteristics. This process involves gene expression and the production of proteins that ultimately determine an individual's traits. Choice B is incorrect because genes do not have a direct role in preventing foreign particles from entering the body; this function is primarily carried out by the immune system. Choice C is incorrect as genes do not specifically work with lutein to influence development; genes operate independently to regulate trait expression. Choice D is incorrect as genes are not responsible for transferring oxygen in the bloodstream; this function is carried out by red blood cells and hemoglobin.
3. A client at 27 weeks of gestation with preeclampsia is being assessed by a nurse. Which of the following findings should the nurse report to the provider?
- A. Urine protein concentration of 200 mg/24 hr.
- B. Creatinine level of 0.8 mg/dL
- C. Hemoglobin level of 14.8 g/dL
- D. Platelet count of 60,000/mm3
Correct answer: D
Rationale: A platelet count of 60,000/mm3 is significantly low and can indicate HELLP syndrome, a severe complication of preeclampsia that involves hemolysis, elevated liver enzymes, and low platelet count. HELLP syndrome requires prompt medical intervention to prevent serious maternal and fetal complications. The other findings listed are within normal limits or not directly related to the severe condition associated with HELLP syndrome.
4. The actual sets of traits that people exhibit are called their genotypes.
- A. TRUE
- B. FALSE
- C. Possibly
- D. Always
Correct answer: B
Rationale: The actual sets of traits that people exhibit are called phenotypes, not genotypes. Genotypes refer to the genetic makeup of an individual.
5. Which of the following is most likely to develop sickle cell anemia?
- A. European American
- B. Native American
- C. African American
- D. Asian American
Correct answer: C
Rationale: Sickle cell anemia is most commonly found in individuals of African American descent. This is because sickle cell trait provides some protection against malaria, and historically, regions where malaria is or was prevalent have higher rates of sickle cell anemia. Therefore, individuals with African ancestry are at a higher risk of developing sickle cell anemia compared to other populations. Choices A, B, and D are less likely to develop sickle cell anemia due to lower genetic prevalence in their respective populations.
