The nurse is counseling a pregnant patient who is concerned about gestational diabetes. The patient has a family history of diabetes and is overweight. Which statement by the nurse would be most appropriate?
- A. Gestational diabetes usually resolves after delivery and will not affect your baby.
- B. Gestational diabetes can cause excessive birth weight, which may lead to delivery complications.
- C. You should avoid eating carbohydrates entirely to manage gestational diabetes.
- D. Gestational diabetes has no impact on your risk for developing type 2 diabetes later in life.
Correct Answer: B
Rationale: The correct answer is B because gestational diabetes can indeed cause excessive birth weight, leading to delivery complications such as shoulder dystocia and cesarean section. This is important for the patient to be aware of to ensure the health and safety of both herself and her baby.
Choice A is incorrect because gestational diabetes can persist after delivery and may increase the risk of developing type 2 diabetes later in life for both the mother and the baby.
Choice C is incorrect because pregnant women with gestational diabetes still need carbohydrates for proper nutrition; however, they should monitor their carbohydrate intake and choose complex carbohydrates to manage blood sugar levels.
Choice D is incorrect because having gestational diabetes does increase the risk of developing type 2 diabetes later in life. It is important for the patient to understand this potential risk and take steps to manage their health accordingly.
The nurse is caring for a pregnant patient who is 22 weeks gestation and is concerned about her weight gain. Which of the following statements by the patient indicates the need for further teaching?
- A. I should aim to gain 1 to 2 pounds per week during my pregnancy.
- B. I will avoid eating extra food to prevent excessive weight gain.

- D. I will maintain a healthy diet and exercise regularly to support my pregnancy.
Correct Answer: C
Rationale: Correct Answer: C - "I can eat for two during my pregnancy to ensure the baby's growth."
Rationale:
1. Eating for two is a common misconception; the pregnant woman only needs an additional 300-500 calories per day.
2. Overeating can lead to excessive weight gain which may pose risks to both the mother and the baby.
3. The statement does not reflect an accurate understanding of healthy nutrition during pregnancy.
Summary of Incorrect Choices:
A: Choosing to gain 1 to 2 pounds per week aligns with healthy weight gain during pregnancy.
B: Avoiding excessive food intake is an appropriate strategy to prevent excessive weight gain.
D: Maintaining a healthy diet and regular exercise are essential for supporting a healthy pregnancy.
The nurse is caring for a pregnant patient who is 36 weeks gestation and is concerned about preterm labor. Which of the following is a key sign of preterm labor?
- A. Regular contractions every 10 minutes or less
- B. Decreased fetal movement
- C. Mild cramping and back pain
- D. Increased energy levels and appetite
Correct Answer: A
Rationale: The correct answer is A: Regular contractions every 10 minutes or less. This is a key sign of preterm labor because regular contractions at this frequency could indicate the onset of labor before the full term. Contractions help to thin and dilate the cervix, leading to the birth of the baby. Decreased fetal movement (B) is a concerning sign but not a definitive indicator of preterm labor. Mild cramping and back pain (C) can be common in pregnancy and may not necessarily indicate preterm labor. Increased energy levels and appetite (D) are not typical signs of preterm labor, as the body usually shows signs of preparing for labor rather than increased energy levels.
