A 35-year-old pregnant woman with irregular periods, G4 T2 PO A1 L2 is 28 weeks pregnant by the last ultrasound, when she experiences bright red and painless vaginal bleeding, fetal contour is easily assessed, and uterine tone is normal. On her arrival at the hospital, what would be an expected diagnostic procedure or test to confirm the diagnosis?

Select one:

A.

Vaginal Ultrasound for placental location

B.

Amniocentesis for fetal lung maturity

C.

Abdominal Ultrasound for placental location

D.

Contraction stress test (CST)

Answer and Explanation

The Correct Answer is A

a.    This would help determine the location of the placenta and whether placenta previa is present, which can cause painless vaginal bleeding.
b.    This is not typically done for diagnosis of painless vaginal bleeding.
c.    While an abdominal ultrasound can also determine the location of the placenta, a vaginal ultrasound is more accurate for this purpose.

Correct Answer is A

Explanation

a. Variable decelerations occur due to umbilical cord compression, typically when the cord is compressed during contractions or when the cord is wrapped around the fetal neck or body.
b. Early decelerations are typically related to fetal head compression and are not associated with variable decelerations.
c. Late decelerations are caused by uteroplacental insufficiency and are not associated with variable decelerations.
d. IV narcotic analgesics can cause late decelerations, not variable decelerations.

Correct Answer is B

Explanation

a. Not every woman ovulates on day 14 of her cycle, and the basal temperature only rises after ovulation, not before.
b. The basal temperature is the lowest body temperature during a 24-hour period.

It is usually measured first thing in the morning before any physical activity or eating. The basal temperature can indicate when a woman is ovulating, as it tends to rise slightly (about 0.5°F or 0.3°C) after ovulation and remain elevated until the next menstrual period. By tracking the basal temperature over several cycles, a woman can identify her most fertile days and plan accordingly.
c. Intercourse can affect the body temperature and give a false reading.

d. The basal temperature is influenced by factors such as food, drink, stress, and activity, so it should be measured before any of these occur.
