A nurse is reinforcing preconception teaching with a client. Which of the following statements should the nurse include regarding alcohol consumption during pregnancy?

A. Decreasing fluid intake, especially during pregnancy, is not advisable as it can lead to dehydration and other complications.

B. While urinary frequency varies between individuals, it follows predictable patterns during pregnancy, influenced by hormonal and anatomical changes.

C. Increased urinary frequency is common in the first trimester due to hormonal changes and uterine growth but typically decreases by the second trimester. It often returns in the third trimester when the enlarging uterus exerts pressure on the bladder.

D. Poor bladder tone is not a standard explanation for continued urinary frequency during pregnancy; hormonal and anatomical factors are the primary causes.

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.
