Correct Answer is A
Explanation
a. In this case, the woman is pregnant for the fourth time, so her gravidity is 4.
She has one child born at 39 weeks, another child born at 40 weeks, and one child born at 36.2 weeks. The first two are considered term births, and the last one is considered a preterm birth. Therefore, her term is 1 and her preterm is 2. She has no abortions, so her abortion is 0. She has three living children, so her living children is 3. Hence, her GTPAL is 4-2-1-0-3.
b. This indicates 1 full-term pregnancy, 1 preterm pregnancy, and 3 living child.
c. This would indicate 1 full-term pregnancy, 2 preterm pregnancies, and 3 living children.
d. 4-3-0-0-3: This would indicate 3 full-term pregnancies and 3 living children.
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.
