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.

A. Neural tube defects. B. Type 1 diabetes mellitus C. Congenital heart defects D. Intrauterine growth restriction

Correct Answer is D

Explanation

a. Smoking is not directly associated with neural tube defects.
b. Smoking is not directly associated with type 1 diabetes mellitus.
c. While smoking during pregnancy is harmful, it is not specifically associated with congenital heart defects.
d. Smoking during pregnancy is a known risk factor for intrauterine growth restriction, which can lead to low birth weight and other complications for the newborn
