Which purpose of placental functioning should the nurse include in prenatal education?
It maintains the temperature of the fetus
It prevents all antibodies and viruses from passing to the fetus
It is responsible for nutrient and gas exchange
It cushions and protects the fetus
The Correct Answer is C
A. It maintains the temperature of the fetus: The placenta does not directly regulate the fetus's body temperature. The amniotic fluid and the mother's body contribute to temperature regulation, but this is not the primary function of the placenta.
B. It prevents all antibodies and viruses from passing to the fetus: The placenta acts as a selective barrier, allowing some substances, such as antibodies, to pass through while blocking others, like certain viruses. However, it does not prevent all viruses or harmful substances from reaching the fetus.
C. It is responsible for nutrient and gas exchange: The placenta plays a critical role in exchanging nutrients, oxygen, and waste products between the mother and fetus. This exchange is essential for fetal growth and development, making it one of the primary functions of the placenta.
D. It cushions and protects the fetus: While the amniotic fluid and sac offer cushioning and physical protection, the placenta's main function is nutrient and gas exchange. The placenta does not serve as a cushion for the fetus; that role is primarily fulfilled by the amniotic fluid.

Correct Answer is ["A","B","D"]
Explanation
A. Parent was abused as a child: Individuals who were abused as children are at a higher risk of becoming perpetrators of abuse themselves. This cycle of abuse is often related to learned behaviors, trauma, and unresolved emotional issues from childhood.
B. Young age of parent: Young parents, especially teenagers, may face difficulties in coping with the responsibilities of raising a child, increasing the likelihood of stress and the potential for abusive behaviors. Their lack of maturity and experience can be risk factors for abuse.
C. Living in a single-family home: While living in a single-parent household can be challenging, it does not directly increase the risk of child abuse. Many single-parent households provide loving and supportive environments for children.
D. Low income, financial stress: Financial strain and low income can contribute to stress, which may increase the risk of child abuse. Lack of resources, unstable housing, and worries about basic needs can elevate tension in the home, potentially leading to abusive behaviors.
E. Being married: Marriage, in itself, is not a direct risk factor for child abuse. In fact children in stable, supportive marriages are less likely to experience abuse. It is the relationship dynamics and other stressors, not just marital status, that matter in child abuse risk.
Correct Answer is A
Explanation
A. Influenza vaccine: The influenza vaccine is safe and recommended during pregnancy, particularly in the second and third trimesters. It helps protect both the mother and the unborn child from the flu, which can cause severe complications in pregnant women.
B. Varivax vaccine: The Varivax vaccine, which protects against chickenpox, is a live attenuated vaccine and should not be given during pregnancy due to potential risks to the fetus. If a woman has not had chickenpox, she should be vaccinated before becoming pregnant.
C. MMR vaccine: The MMR vaccine, which protects against measles, mumps, and rubella, is a live attenuated vaccine and should not be given during pregnancy. It is recommended to wait until after pregnancy to receive this vaccine, as it can pose risks to the developing fetus.
D. Gardasil vaccine: The Gardasil vaccine, which protects against human papillomavirus (HPV), is not recommended during pregnancy. It is advised to delay vaccination until after pregnancy. The potential risks are not well established, so it is typically avoided.
