1. Which of the following statements is true of sickle-cell anemia?

• A. It is typically managed with treatments such as pain relief medications.
• B. It is caused by a mutation in the beta-globin gene.
• C. It leads to the obstruction of small blood vessels and decreased oxygen delivery.
• D. It is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent.

Correct answer: C

Rationale: The correct answer is C. Sickle-cell anemia results from a mutation in the beta-globin gene, causing red blood cells to become sickle-shaped. These misshapen cells can obstruct small blood vessels, leading to reduced oxygen delivery to tissues. Choices A, B, and D are incorrect because sickle-cell anemia is typically managed with treatments such as pain relief medications, hydration, and in severe cases, blood transfusions. It is caused by a specific mutation in the beta-globin gene, not by the inability to metabolize phenylalanine. Additionally, sickle-cell anemia is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent, not exclusive to any specific gender.

2. A primiparous woman presents in labor with the following labs: hemoglobin 10.9 g/dL, hematocrit 29%, hepatitis surface antigen positive, Group B Streptococcus positive, and rubella non-immune. Which intervention should the nurse implement?

• A. Transfuse 2 units of packed red blood cells.
• B. Give measles, mumps, rubella vaccine 0.5 mL.
• C. Administer ampicillin 2 grams intravenously.
• D. Inject hepatitis B immune globulin 0.5 milliliters.

Correct answer: C

Rationale: The correct intervention in this scenario is to administer ampicillin 2 grams intravenously. This is crucial to prevent Group B Streptococcus infection in the newborn during delivery. Option A, transfusing packed red blood cells, is not indicated based on the hemoglobin and hematocrit levels provided. Option B, giving measles, mumps, rubella vaccine, is not necessary at this time. Option D, injecting hepatitis B immune globulin, is not appropriate for the conditions presented in the question.

3. _____ is a life-threatening disease, characterized by high blood pressure that may afflict women late in the second or early in the third trimester.

• A. Rubella
• B. Syphilis
• C. Preeclampsia
• D. Phenylketonuria

Correct answer: C

Rationale: Preeclampsia is a serious pregnancy complication characterized by high blood pressure that typically occurs in the second half of pregnancy. If left untreated, it can lead to severe complications for both the mother and the baby. Rubella (choice A) is a viral infection that can harm the developing fetus but is not directly related to high blood pressure in pregnancy. Syphilis (choice B) is a sexually transmitted infection that can affect pregnancy but does not specifically cause high blood pressure. Phenylketonuria (choice D) is a genetic disorder that affects metabolism and is not associated with high blood pressure in pregnancy.

4. What is the highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy?

• A. Assessing FHR and maternal vital signs.
• B. Performing a venipuncture for hemoglobin and hematocrit levels.
• C. Placing clean disposable pads to collect any drainage.
• D. Monitoring uterine contractions.

Correct answer: A

Rationale: The highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy is to assess the fetal heart rate (FHR) and maternal vital signs. This assessment is crucial in determining the extent of blood loss and its impact on both the mother and the fetus. Ensuring the well-being of both the mother and the fetus is the top priority in this situation. While obtaining hemoglobin and hematocrit levels is important, it can be done after the initial assessment. Placing clean disposable pads is necessary for managing any drainage but does not take precedence over assessing vital signs. Monitoring uterine contractions is important but is not the highest priority when compared to assessing the FHR and maternal vital signs.

5. What causes Down's syndrome?

• A. Alcohol abuse by the mother at the time of conception.
• B. Sex-linked chromosomal abnormalities.
• C. An extra chromosome on the 21st pair.
• D. Drug abuse by the mother during pregnancy.

Correct answer: C

Rationale: Down's syndrome, also known as trisomy 21, is caused by the presence of an extra chromosome on the 21st pair. Choice A is incorrect as alcohol abuse is not the cause of Down's syndrome. Choice B is incorrect because Down's syndrome is not related to sex-linked chromosomal abnormalities. Choice D is also incorrect as drug abuse by the mother during pregnancy is not the cause of Down's syndrome.
