A nurse is caring for a laboring person who is receiving oxytocin for labor induction. What is the priority intervention when uterine hyperstimulation occurs?
- A. stop the oxytocin infusion
- B. increase the oxytocin infusion
- C. administer IV fluids
- D. administer an epidural
Correct Answer: D
Rationale: The correct answer is D: administer an epidural. Uterine hyperstimulation during labor can lead to fetal distress and complications. Administering an epidural can help manage pain and relax the uterus, reducing the risk of hyperstimulation. Stopping the oxytocin infusion (choice A) is also important, but managing the uterine contractions with an epidural takes priority. Increasing the oxytocin infusion (choice B) would exacerbate the hyperstimulation. Administering IV fluids (choice C) may be helpful, but it does not directly address the uterine hyperstimulation.
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.
A nurse is caring for a laboring person and is monitoring for signs of fetal distress. Which finding is the most concerning in this situation?
- A. Late decelerations
- B. Bradycardia
- C. Tachycardia
- D. Variable decelerations
Correct Answer: A
Rationale: The correct answer is A: Late decelerations. Late decelerations indicate uteroplacental insufficiency, which can lead to fetal hypoxia and distress. This is the most concerning finding as it indicates a problem with oxygen delivery to the fetus. Bradycardia (B) and Tachycardia (C) can also be concerning, but late decelerations are more specific to fetal distress. Variable decelerations (D) are caused by cord compression and are concerning but not as indicative of fetal distress as late decelerations.
Where is the usual location for implantation of the zygote?
- A. Upper section of the posterior uterine wall
- B. Lower portion of the uterus near the cervical os
- C. Inner third of the fallopian tube near the uterus
- D. Lateral aspect of the uterine wall
Correct Answer: A
Rationale: The zygote usually implants in the upper section of the posterior uterine wall.
The nurse is educating a pregnant patient about the importance of exercise during pregnancy. Which statement by the patient indicates that the teaching has been effective?
- A. I should avoid any exercise because it could harm my baby.
- B. Moderate exercise is safe and helps prepare my body for labor.
- C. I should only exercise during the second trimester to avoid complications.
- D. I can perform any type of exercise as long as I am comfortable.
Correct Answer: B
Rationale: The correct answer is B because it acknowledges the importance of moderate exercise during pregnancy to prepare the body for labor. This shows understanding of the benefits of exercise for both the mother and baby. Choice A is incorrect as it promotes complete avoidance of exercise, which is not recommended. Choice C is incorrect because exercise is beneficial throughout pregnancy, not just in the second trimester. Choice D is incorrect because some exercises may not be safe during pregnancy, so comfort alone is not the only factor to consider.
