The United States ranks poorly in terms of worldwide infant mortality rates. Which factor has the greatest impact on decreasing the mortality rate of infants?
Correct Answer: B
Rationale: The correct answer is B: Ensuring early and adequate prenatal care. Prenatal care plays a crucial role in monitoring the health of the mother and the developing fetus, detecting and managing any potential health issues early on, and providing essential education on nutrition and healthy practices. This ultimately leads to healthier pregnancies, reduced risks of complications, and improved outcomes for both the mother and the infant. Providing more women's shelters (A) may help address social issues but does not directly impact infant mortality rates. Resolving language and cultural differences (C) is important for effective healthcare delivery but is not the primary factor in reducing infant mortality. Enrolling pregnant women in Medicaid (D) is beneficial for access to healthcare but does not address the importance of early and adequate prenatal care in reducing infant mortality rates.
