Extract:
Client in second trimester of pregnancy
Question 1 of 5
A nurse is collecting data from a client who is in her second trimester of pregnancy. The nurse should recognize which of the following findings as an expected physiologic change during pregnancy?
Correct Answer: B
Rationale: An increase in lordosis is expected due to the shifting center of gravity from uterine growth. Posterior neck flexion is not typical, pelvic joint mobility increases, and abdominal muscle tone decreases.
Extract:
Client at 8 weeks of gestation
Question 2 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:
Client who thinks she might be pregnant
Question 3 of 5
A nurse is caring for a client who tells the nurse that she thinks she might be pregnant because she is able to feel the baby move. Which of the following statements should the nurse make?
Correct Answer: B
Rationale: Feeling fetal movement (quickening) is a presumptive sign of pregnancy, as it is subjective and can be mistaken for other sensations. Probable and positive signs are objective, and 'possible' is not a recognized category.

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:
Client at 10 weeks of gestation
Question 5 of 5
A nurse is assisting in the care of a client at 10 weeks of gestation who asks how the biological sex of the fetus is determined. Which of the following responses should the nurse make?
Correct Answer: B
Rationale: Biological sex is determined at fertilization by the combination of sex chromosomes (XX or XY). Implantation, foramen ovale, and blastocyst formation do not determine sex.
