Maternal Fetal Monitoring Questions
Question 1 of 5
A nurse is assisting with a vaginal delivery. What is the most important action when the fetal head begins to crown?
Correct Answer: A
Rationale: The correct answer is A: apply gentle downward pressure. This action helps prevent rapid delivery, reducing the risk of tearing and allowing the perineum to stretch gradually. It also helps control the delivery, ensuring a safe and controlled birth process. Performing perineal massage (B) is beneficial during the pushing stage but is not the most important action when the head crowns. Performing a vaginal exam (C) is unnecessary and may increase the risk of infection. Assisting with breathing exercises (D) is important during labor but not specifically when the head crowns.
Question 2 of 5
What organ does the ductus venosus shunt blood away from in fetal circulation?
Correct Answer: A
Rationale: In fetal circulation, the ductus venosus is a shunt that directs oxygenated blood from the umbilical vein towards the inferior vena cava, bypassing the liver. The correct answer is A) Liver. The liver is not the primary site of blood exchange in the fetal circulation as it is not fully functional until after birth. By shunting blood away from the liver, the ductus venosus helps optimize the amount of oxygenated blood reaching the fetal systemic circulation. Options B) Heart, C) Lungs, and D) Kidneys are incorrect because the ductus venosus does not shunt blood away from these organs in fetal circulation. The heart receives oxygenated blood from the placenta via the umbilical vein, the lungs are not fully functional in utero, and the kidneys are not major players in fetal circulation. Understanding fetal circulation is crucial in obstetrics and neonatology as it impacts maternal-fetal health, fetal development, and management of neonatal complications. Knowledge of fetal circulation is essential for healthcare professionals involved in maternal-fetal monitoring, such as obstetricians, midwives, and neonatal nurses.
Question 3 of 5
The nurse is presenting a conference on gene dominance. What does the nurse report as the percentage of children carrying the dominant gene if one parent has a dominant gene and the other parent does not?
Correct Answer: C
Rationale: In the context of gene dominance, understanding the principles of inheritance is crucial. When one parent carries a dominant gene and the other parent does not, the dominant gene will be expressed in the offspring. This is because dominant genes mask the expression of recessive genes. Therefore, the correct answer is C) 50%. Option A) 10% is incorrect because, in this scenario, the dominant gene will be expressed in 50% of the offspring, not just 10%. Option B) 25% is incorrect as well because it represents the percentage of offspring who would carry two recessive genes if both parents were carriers of the recessive gene. Option D) 100% is incorrect because if one parent does not carry the dominant gene, then it is not possible for all children to carry the dominant gene. In an educational context, comprehending gene dominance is fundamental for healthcare professionals, especially in pharmacology and genetics. Understanding how genes are inherited is vital for predicting the likelihood of certain traits or genetic conditions being passed down through generations. This knowledge is essential for providing informed genetic counseling to patients and making decisions about treatment options based on genetic factors.
Question 4 of 5
What are the functions of amniotic fluid? (Select all that apply.)
Correct Answer: A
Rationale: The amniotic fluid provides maintenance of even temperature; prevents amnion from adhering to fetal skin; allows buoyancy, symmetrical growth, and fetal movement; and acts as a cushion for the fetus. Although the fetus does swallow amniotic fluid, it has no nutritional value. Impeding excessive fetal movement and lubricating fetal skin are not primary functions of amniotic fluid.
Question 5 of 5
A pregnant patient’s biophysical profile score is 8. The patient asks the nurse to explain the results. What is the nurse’s most appropriate response?
Correct Answer: A
Rationale: The most appropriate response for the nurse to provide to the pregnant patient in this scenario is option A) The test results are within normal limits. This response is correct because a biophysical profile score of 8 is considered normal. A biophysical profile assesses the baby's well-being by evaluating factors such as fetal heart rate, fetal movement, breathing movements, muscle tone, and the amount of amniotic fluid. Option B) Immediate birth by cesarean birth is being considered is incorrect because a score of 8 does not typically warrant immediate delivery. Option C) Further testing will be performed to determine the meaning of this score is also incorrect as a score of 8 is generally considered reassuring and does not typically require additional testing. Option D) An obstetric specialist will evaluate the results of this profile and, within the next week, will inform you of your options regarding birth is incorrect as immediate action is not necessary based on the provided score. In an educational context, it is crucial for healthcare providers to understand the interpretation of biophysical profile scores to provide accurate information and reassurance to pregnant patients. Clear communication with patients about test results can help alleviate anxiety and ensure they are well-informed about their pregnancy status.
