Final answer:
The nurse should include the manifestation of decreased fetal movement.
Step-by-step explanation:
When teaching a client at 35 weeks of gestation about manifestations of potential pregnancy complications, the nurse should include the manifestation of decreased fetal movement. Decreased fetal movement could indicate a problem with the baby's well-being and should be reported to the healthcare provider. It is important for the nurse to emphasize the importance of monitoring fetal movements regularly and seeking medical advice if there are any concerns.
