Which of the following are presumptive signs of pregnancy? Select all that apply.

Pregnancy is identified through presumptive, probable, and positive signs, categorized by specificity. Presumptive signsare subjectiveand experienced only by the pregnant individual. Probable signsare objective, observable by clinicians, but not definitive. Positive signsare conclusiveand confirm the presence of a fetus. Presumptive signsinclude nausea and vomiting, amenorrhea, breast tenderness, fatigue, and quickening(first fetal movement felt by the mother, usually at 16–20 weeks). These signs can result from causes other than pregnancy, thus are not diagnostic.

Rationale for correct answers

1.Amenorrhea is a presumptive sign because it is a subjective experience commonly caused by pregnancy. It occurs due to suppression of the hypothalamic–pituitary–ovarian axis by rising hCG and progesterone.

3.Nausea and vomiting are presumptive signs caused by rising hCG levels stimulating the chemoreceptor trigger zone. These symptoms are subjective and occur in other conditions, making them non-definitive.

5.Quickening refers to the woman’s first perception of fetal movement, usually between 16–20 weeks. It is a subjective experience and can be confused with gastrointestinal activity, classifying it as presumptive.

Rationale for incorrect answers

2.Fetal heart sounds are a positive sign. They provide direct evidence of fetal life and are detected by Doppler around 10–12 weeks. This confirms pregnancy beyond doubt.

4.Uterine enlargement is a probable sign. It is an objective finding noted during bimanual examination or ultrasound but may also result from tumors or fibroids. It suggests pregnancy but is not conclusive without positive signs.

Take home points

• Presumptive signs are subjective and felt only by the pregnant individual.

• Amenorrhea, nausea, and quickening are classic presumptive signs.

• Fetal heart tones and uterine growth are not presumptive—they are positive and probable, respectively.

• Presumptive signs must be confirmed with objective or positive findings.

Pregnancy is identified through presumptive, probable, and positive signs, categorized by specificity. Probable signsare objectivefindings observed by clinicians that strongly suggest pregnancy but are not definitive. These include Goodell’s sign, Chadwick’s sign, Hegar’s sign, and a positive pregnancy test. Goodell’s signis the softening of the cervical tipdue to increased vascularization caused by rising estrogen levels. It typically occurs around 6–8 weeksof gestation. Unlike presumptive signs, probable signs are observable and measurable, but still not conclusive without positive confirmation.

Rationale for correct answers

2.Goodell’s sign refers to softening of the cervical tip, detectable during a pelvic exam around 6–8 weeks. This change occurs due to increased vascularity and hypertrophy from elevated estrogen, classifying it as a probable sign of pregnancy.

Rationale for incorrect answers

1.Bluish discoloration of the vaginal mucosa is Chadwick’s sign, not Goodell’s. It results from increased blood flow to the cervix and vagina and appears around 6–8 weeks, also classified as a probable sign.

3.Softening of the lower uterine segment is Hegar’s sign, not Goodell’s. It is detected during bimanual examination around 6–12 weeks and reflects uterine softening below the cervix, also a probable sign.

4.Passive movement of the unengaged fetus during palpation is ballottement, not Goodell’s. It occurs between 16–18 weeks and is another probable sign, observed during a physical exam when the fetus rebounds after being pushed.

Take home points

• Goodell’s sign is cervical softening due to increased vascularization from estrogen.

• Chadwick’s sign is bluish discoloration of the cervix and vaginal mucosa.

• Hegar’s sign is softening of the lower uterine segment below the cervix.

• Ballottement is the passive rebound of the fetus when tapped during a pelvic exam.
