A pregnant woman asks the nurse, "Will I be able to have a vaginal delivery?" The nurse knows that which type of female pelvis is optimal for passage of the fetal head?
Gynecoid
Platypelloid
Android
Anthropoid
The Correct Answer is A
A. The gynecoid pelvis is considered the most favorable for vaginal delivery due to its rounded shape, wide pelvic inlet, and spacious dimensions, which facilitate the passage of the fetal head.
B. The platypelloid pelvis is flat and wide, often posing challenges for vaginal delivery due to its narrow anteroposterior diameter.
C. The android pelvis has a heart-shaped inlet, making it less favorable for vaginal delivery as it can cause difficulty in fetal descent.
D. The anthropoid pelvis has an oval shape and is more favorable for vaginal delivery than android or platypelloid pelves, but it is still less optimal compared to the gynecoid pelvis.

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.
