ATI LPN N105 Maternity Exam Questions
Extract:
Expectant parents
Question 1 of 5
The nurse is educating a class of expectant parents about fetal development. What is considered fetal age of viability?
Correct Answer: C
Rationale: At 8 weeks, the embryo is transitioning into the fetal stage and is not viable outside the womb. At 14 weeks, the fetus is too underdeveloped for survival. While 24 weeks is considered reasonable viability with intensive support, 20 weeks is often cited as the lower threshold due to improved neonatal care.
Extract:
Client and reproductive partner
Question 2 of 5
A nurse is providing education to a client and their reproductive partner when the client asks about testing for hereditary genetic disorders, particularly the type their partner has. Which of the following responses should the nurse provide:
Correct Answer: C
Rationale: Offering genetic testing to both partners is the correct response as it enables the identification of hereditary risks and provides information about the likelihood of passing on genetic disorders to their children. Testing only one partner is insufficient, and testing can be done preconception.

Client at 8 weeks of gestation
Question 3 of 5
A nurse in a provider's office is caring for a client who is at 8 weeks of gestation and asks about increased risk for blood clots. Which of the following statements should the nurse make?
Correct Answer: C
Rationale: Increased blood plasma volume and elevated clotting factors during pregnancy contribute to a hypercoagulable state, increasing thrombosis risk. Procoagulant factors increase, not decrease, and natural anticoagulants decrease. Platelet counts may slightly decrease due to hemodilution.
Extract:
None
Question 4 of 5
In fetal circulation, the ductus venosus diverts blood from which of the following organs?
Correct Answer: D
Rationale: The ductus venosus allows oxygen-rich blood from the umbilical vein to bypass the liver and flow into the inferior vena cava, ensuring well-oxygenated blood reaches vital fetal organs. The lungs are bypassed by the foramen ovale and ductus arteriosus, and the heart and kidneys are not bypassed by the ductus venosus.
Extract:
Newborn
Question 5 of 5
A nurse is caring for a newborn. How many blood vessels should the nurse expect to observe in the newborn's umbilical cord?
Correct Answer: A
Rationale: The umbilical cord typically contains two arteries that carry deoxygenated blood from the fetus to the placenta and one vein that carries oxygenated blood from the placenta to the fetus. Two veins or one artery are not typical, and single umbilical artery is an abnormality.
