A patient in labor begins to experience significant vaginal bleeding. What is the first step the nurse should take?
- A. Administer oxygen to the patient
- B. Check for a cord prolapse
- C. Perform a vaginal examination
- D. Perform a vaginal examination
Correct Answer: B
Rationale: The correct answer is B: Check for a cord prolapse. This is the first step because cord prolapse is a critical emergency that can lead to fetal compromise. By checking for cord prolapse, the nurse can quickly assess the situation and take appropriate actions to relieve pressure on the cord. Administering oxygen (choice A) may be necessary later but not the first step. Performing a vaginal examination (choices C and D) can exacerbate the situation by pushing the cord further into the birth canal.

The nurse is caring for a patient who is 32 weeks pregnant and is concerned about gestational diabetes. Which statement by the nurse is most appropriate?
- A. Gestational diabetes is usually temporary and will resolve after delivery.
- B. Gestational diabetes increases the risk of the baby developing diabetes later in life.
- C. You can control gestational diabetes with regular exercise and a healthy diet.
- D. Gestational diabetes is rare and typically does not require treatment.
Correct Answer: C
Rationale: The correct answer is C: "You can control gestational diabetes with regular exercise and a healthy diet." This is the most appropriate statement because managing gestational diabetes through lifestyle modifications like regular exercise and a healthy diet is a key component of treatment. By controlling blood sugar levels through these methods, complications for both the mother and baby can be reduced.
Choice A is incorrect because gestational diabetes may not always resolve after delivery and can increase the risk of developing type 2 diabetes in the future. Choice B is incorrect as it confuses the risk of the baby developing diabetes with the mother's condition. Choice D is incorrect as gestational diabetes is not rare and requires monitoring and sometimes treatment to manage effectively.
The nurse is caring for a pregnant client who is a vegan. Which of the following foods should the nurse suggest the client consume as substitutes for restricted foods?
- A. Tofu, legumes, broccoli.
- B. Corn, yams, green beans.
- C. Potatoes, parsnips, turnips.
- D. Cheese, yogurt, fish.
Correct Answer: A
Rationale: Tofu, legumes, and broccoli provide essential nutrients like protein, iron, and calcium that are often lacking in a vegan diet. Corn, yams, and green beans offer carbohydrates and vitamins but lack sufficient protein sources. Potatoes, parsnips, and turnips are starchy vegetables with limited nutritional variety. Cheese, yogurt, and fish are non-vegan options.
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.
