What statement indicates a woman has correct information about oogenesis?
"Women have all of their ova at the time they are born."
"Women make fewer ova as they age."
"Ova production begins at birth and continues until puberty."
"New ova are made every month from puberty to climacteric."
The Correct Answer is A
A. Women have all of their ova at birth. Oogenesis, the process of egg development, occurs in the fetus, and women are born with all the eggs (ova) they will ever have. The number of eggs decreases over time.
B. Women make fewer ova as they age is correct in a sense, but the statement is misleading because the number of eggs actually decreases after birth, not through an ongoing process of "making fewer."
C. Ova production begins at birth and continues until puberty is incorrect. Ova are formed during fetal development, but no new eggs are produced after birth.
D. New ova are made every month from puberty to climacteric is incorrect. While ova mature and are released monthly during a woman's reproductive years, they are not newly made each month. The ovary contains a finite number of immature eggs at birth.

Correct Answer is B
Explanation
A. Posterior neck flexion is not a normal physiologic change in pregnancy; it is more associated with musculoskeletal issues unrelated to pregnancy.
B. An increase in lordosis is a common and expected change during pregnancy. As the uterus enlarges, the center of gravity shifts forward, causing an increase in the curvature of the lower back (lordosis).
C. Decreased mobility of pelvic joints is not typical. In fact, hormonal changes during pregnancy cause increased mobility of the pelvic joints (e.g., the pubic symphysis) to prepare for labor.
D. Increased abdominal muscle tone is not typical during pregnancy. In fact, abdominal muscles often stretch and weaken as the pregnancy progresses to accommodate the growing fetus.
Correct Answer is C
Explanation
A. A decrease in saliva production may aggravate the disorder is not correct. In fact, hyperemesis gravidarum is often associated with an increase in saliva production (ptyalism) rather than a decrease.
B. Decreasing gastric secretions lead to increased nausea is inaccurate. The issue in hyperemesis gravidarum is typically an increase in nausea and vomiting, not a direct link to decreased gastric secretions.
C. An increase in human chorionic gonadotropin (hCG) levels may contribute to this disorder is correct. Elevated hCG levels are thought to play a role in the development of hyperemesis gravidarum, as they may contribute to increased nausea and vomiting.
D. Symptoms begin and are most severe during the second trimester of pregnancy is incorrect. Hyperemesis gravidarum typically starts in the first trimester and can persist beyond that if not managed. Symptoms do not usually peak in the second trimester.
