A patient in her first trimester complains of nausea and vomiting. She asks, "Why does this happen?” The nurse's best response is:

Correct Answer: B

Rationale: The correct answer is B: "It may be due to changes in hormones." During the first trimester of pregnancy, hormonal changes, particularly an increase in human chorionic gonadotropin (hCG) and estrogen levels, can trigger nausea and vomiting, commonly known as morning sickness. These hormonal fluctuations can affect the gastrointestinal system, leading to symptoms of nausea and vomiting. The other choices are incorrect because: A) an increase in gastric motility typically occurs in later stages of pregnancy, not the first trimester; C) an increase in glucose levels is not directly linked to nausea and vomiting in early pregnancy; D) a decrease in gastric secretions is unlikely to be the primary cause of nausea and vomiting in the first trimester.
