The nurse is caring for a client who visits the prenatal clinic stating she thinks she may be pregnant because she is able to feel the baby move. Which of the following statements by the nurse is an appropriate response?

A. "This is a probable sign of pregnancy.": Probable signs include objective findings observed by the examiner—such as uterine enlargement, positive pregnancy test, or Hegar’s sign—but not felt by the client alone. Feeling fetal movement is subjective, not probable. B. "This is a positive sign of pregnancy.": Positive signs are definitive indicators confirmed by the examiner, such as visualization of the fetus on ultrasound, detection of fetal heart tones, or palpation of fetal movements by the provider. The client’s perception alone does not confirm pregnancy. C. "This is a possible sign of pregnancy.": The term “possible” is not a standard clinical classification. Pregnancy signs are categorized as presumptive, probable, or positive, so this terminology is inaccurate in describing clinical findings. D. "This is a presumptive sign of pregnancy.": Feeling fetal movement (quickening) is considered a presumptive sign because it is subjective and experienced only by the woman. It suggests pregnancy but is not diagnostic, as similar sensations may occur due to gas or intestinal movement.
