The nurse is caring for a pregnant patient who is 36 weeks gestation and is concerned about preterm labor. Which of the following is a key sign of preterm labor?
Correct Answer: A
Rationale: The correct answer is A: Regular contractions every 10 minutes or less. This is a key sign of preterm labor because regular contractions at this frequency could indicate the onset of labor before the full term. Contractions help to thin and dilate the cervix, leading to the birth of the baby. Decreased fetal movement (B) is a concerning sign but not a definitive indicator of preterm labor. Mild cramping and back pain (C) can be common in pregnancy and may not necessarily indicate preterm labor. Increased energy levels and appetite (D) are not typical signs of preterm labor, as the body usually shows signs of preparing for labor rather than increased energy levels.
