The nurse is providing prenatal education to a patient who is at 20 weeks gestation. Which of the following topics should the nurse prioritize during this visit?
- A. Managing gestational diabetes
- B. Reviewing newborn care practices
- C. Educating about normal pregnancy changes
- D. Discussing postpartum care
Correct Answer: C
Rationale: The correct answer is C: Educating about normal pregnancy changes. At 20 weeks gestation, the priority is to educate the patient about normal physiological changes she may experience during pregnancy. This knowledge helps the patient understand what is considered normal and when to seek medical attention. Managing gestational diabetes (A) is important but typically addressed later in pregnancy. Reviewing newborn care practices (B) and discussing postpartum care (D) are important topics but not a priority at 20 weeks gestation. It is essential to focus on educating the patient about the current stage of pregnancy to promote optimal prenatal care.
