1. In contrast to placenta previa, what is the most prevalent clinical manifestation of abruptio placentae?

• A. Bleeding.
• B. Intense abdominal pain.
• C. Uterine activity.
• D. Cramping.

Correct answer: B

Rationale: The correct answer is B: Intense abdominal pain. Pain is absent with placenta previa but can be agonizing with abruptio placentae. While bleeding may be present in varying degrees for both placental conditions, intense abdominal pain is a distinguishing feature of abruptio placentae. Uterine activity and cramping may be present with both placental conditions, but they are not the most prevalent clinical manifestation of abruptio placentae.

2. 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.

3. A healthcare provider is teaching a prenatal class about immunizations that newborns receive following birth. Which of the following immunizations should the provider include in the teaching?

• A. Hepatitis B
• B. Rotavirus
• C. Pneumococcal
• D. Varicella

Correct answer: A

Rationale: The correct answer is Hepatitis B. Newborns receive the Hepatitis B vaccine shortly after birth to provide protection against the virus. Rotavirus, Pneumococcal, and Varicella vaccines are typically administered at later stages of infancy or childhood, not immediately after birth. Rotavirus vaccine helps prevent severe diarrhea, Pneumococcal vaccine protects against infections like pneumonia and meningitis, and Varicella vaccine prevents chickenpox. However, these vaccines are not part of the routine immunizations given to newborns immediately after birth.

4. Before meiosis, a sperm cell:

• A. contains 46 chromosomes.
• B. contains two X chromosomes.
• C. is significantly larger than an egg cell.
• D. contains both an X and a Y chromosome.

Correct answer: A

Rationale: Before meiosis, a sperm cell contains 46 chromosomes. This is because sperm cells, like other somatic cells, have a diploid number of chromosomes. During meiosis, the number of chromosomes is halved to 23 to combine with an egg cell during fertilization. Choice B is incorrect because a sperm cell carries either an X or a Y chromosome, not both (Choice D). Choice C is incorrect as sperm cells are generally smaller than egg cells, which is an adaptation that aids in motility and penetration of the egg during fertilization.

5. A mother spontaneously delivers a newborn infant in the taxicab while on the way to the hospital. The emergency room nurse reported the mother has active herpes (HSV II) lesions on the vulva. Which intervention should the nurse implement first when admitting the neonate to the nursery?

• A. Document the newborn's temperature on the flow sheet.
• B. Place the newborn in the isolation area of the nursery.
• C. Obtain a blood specimen for a serum glucose level.
• D. Administer the vitamin K injection.

Correct answer: B

Rationale: Newborns exposed to active herpes lesions are at high risk for neonatal herpes, which can be severe. Placing the newborn in isolation is crucial as it helps prevent the spread of the virus and allows for close monitoring. Documenting the newborn's temperature, obtaining a blood specimen for a serum glucose level, and administering the vitamin K injection are important interventions but are not the priority when dealing with a potential infectious risk like neonatal herpes.
