Which of the following is considered a presumptive symptom of pregnancy?
A. Fetal heart tones
B. Cervical softening (Goodell's sign)
C. Amenorrhea
D + urine β-hCG - ANSWER-Correct answer.Amenorrhea is considered a presumptive
sign of pregnancy because many other conditions can cause amenorrhea. Positive
urine pregnancy test is a probable sign but is not conclusive since other conditions can
yield a positive result. The other 2 options are objective signs which indicate the
presence of a fetus.
Pregnancy test (1/4)
The most common test to determine pregnancy is an antibody assay that recognizes
the presence of β-hCG (Human Chorionic Gonadotropin Hormone) that is released from
the fertilized egg. Urine pregnancy tests are considered qualitative tests because they
provide a positive or negative result, either a yes or a no.
The test is set to detect a threshold level of β-hCG hormone present in the urine, usually
between 5-50mIU/mL. If the amount of β-hCG is above the set threshold, or detectable
amount, the test reads as _____ . If the amount of β-hCG is lower than the threshold or
not present at all, the test is _______. - ANSWER-Positive; negative
Pre-Ovulation - ANSWER-Estrogen predominant
Follicular phase of ovulation cycle
Development of follicues up to ovulation
Proliferation phase of uterine cycle
, Post Ovulation - ANSWER-Progesterone predominant
Luteal phase of ovulation cycle
Endometrial changes to accommodate implantation
Secretory phase of uterine cycle
Pregnancy test (2/4)
The level of urine ___ present is detectable in most healthy pregnant females around
the time of the first missed period, or 14 days after fertilization. False positive results are
extremely __ in otherwise healthy females.
Therefore, if a patient presents with a missed period and a ___ urine pregnancy test,
you can make a diagnosis of pregnancy. However, a ___ urine pregnancy test does not
rule out pregnancy. A ___result may occur early in the pregnancy because the amount
of β-hCG may not be high enough to detect according to the threshold as we discussed.
This might happen if fertilization takes place several days after ovulation. Since sperm
can remain viable in the reproductive tract for up to 3 days, the earlier the oocyte is
fertilized, the earlier the amount of β-hCG will be detectable in the urine. Repeating the
test a few days later may actually yield a different result. - ANSWER-bHcg; rare;
positive; negative; negative
Pregnancy test (3/4)
Another testing option is a serum quantitative β-HCG test. This test is different than the
qualitative urine test because it provides an _____ level of HCG in the blood which can
be as low as ___. So, for instance, let's say that a patient presents to your office on the
first day of her missed period. She has had trouble conceiving in previous pregnancies
and she states that she "feels" pregnant, but her home test was negative.
You repeat the urine pregnancy test in the office which is also negative but because
there is a high level of suspicion that she is actually too early in the pregnancy for the
qualitative test to detect β-hCG in the urine, you opt to also perform a venous blood
draw for β-hCG.
