ATI LPN N105 Maternity Exam Questions
Extract:
Couple having unprotected intercourse 3 days before ovulation
Question 1 of 5
When a couple has unprotected sexual intercourse 3 days before the woman ovulates, the risk of the woman becoming pregnant is:
Correct Answer: B
Rationale: The risk is uncertain because sperm can survive up to 5 days, potentially fertilizing the egg after ovulation, which lasts about 24 hours. The fertile period includes days before ovulation.

Expectant parents
Question 2 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 at 28 weeks of gestation with history of one elective abortion at 9 weeks, birth of twins at 36 weeks, and spontaneous abortion at 15 weeks
Question 3 of 5
A nurse in a prenatal clinic is reviewing the medical record of a client who is at 28 weeks of gestation. The client's history reveals one pregnancy terminated by elective abortion at 9 weeks, the birth of twins at 36 weeks, and a spontaneous abortion at 15 weeks of gestation. The nurse should document which of the following as the client's present parity?
Correct Answer: D
Rationale: Parity is the number of pregnancies carried to at least 20 weeks. Only the twin birth at 36 weeks counts, so parity is 1. Twins count as one event, and abortions before 20 weeks do not contribute to parity.
Extract:
Client in first trimester with no rubella immunity
Question 4 of 5
A nurse is reinforcing teaching about immunizations with a woman in her first trimester of pregnancy whose diagnostic testing indicates she does not have immunity to rubella. The nurse should recommend that the client receive a measles, mumps, rubella (MMR) vaccine at which of the following times?
Correct Answer: C
Rationale: The MMR vaccine, a live vaccine, is contraindicated during pregnancy. It should be given post-delivery, ideally when no future pregnancies are planned, to ensure immunity before conception.
Extract:
None
Question 5 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.
