NCLEX Question for probable sign of pregnancy with answer and Rationale

NCLEX Review Question

A 24-year-old woman comes to the clinic because she thinks she is pregnant. Which of the following is a probable sign of pregnancy that the nurse would expect this client to have?

a. Fetal heart tones

b. Nausea and vomiting

c. Amenorrhea

d. Chadwick’s sign

Correct Answer d. . Probable signs of pregnancy are the result of physiologic changes in the pelvic organs and hormonal influences; for example, the mucous membranes of the vulva, vagina, and cervix become bluish (Chadwick’s sign) as a result of hyperemia and proliferation of cells.

Detection of fetal heart tomes is a positive sign (clearly demonstrates the presence of a fetus) of pregnancy that can be detected, with a Doppler instrument, as early as 10 weeks.

Nausea and vomiting is a presumptive symptom of pregnancy because  it can be caused by factors other than pregnancy.

Amenorrhea is a presumptive symptom of pregnancy because it can be caused by factors other than pregnancy.
