A pregnant patient is concerned about preeclampsia, as she has a family history of the condition. Which of the following should the nurse prioritize in monitoring this patient?
- A. Frequent assessment of blood pressure and urine for protein
- B. Monitoring for abdominal pain and nausea
- C. Increasing the patient's fluid intake to avoid dehydration
- D. Encouraging the patient to rest and avoid strenuous activity
Correct Answer: A
Rationale: The correct answer is A because preeclampsia is characterized by high blood pressure and proteinuria. Monitoring blood pressure and urine for protein is essential for early detection and intervention. Choice B is incorrect as abdominal pain and nausea are not specific symptoms of preeclampsia. Choice C is incorrect because excessive fluid intake can worsen preeclampsia. Choice D is incorrect as rest alone cannot prevent or manage preeclampsia. Prioritizing blood pressure and urine monitoring helps identify and manage preeclampsia efficiently.
A 16-year-old, G1 P0000, is being seen at her 10-week gestation visit. She tells the nurse that she felt the baby move that morning. Which of the following responses by the nurse is appropriate?
- A. That is very exciting. The baby must be very healthy.
- B. Would you please describe what you felt for me?
- C. That is impossible. The baby is not big enough yet.
- D. Would you please let me see if I can feel the baby?
Correct Answer: B
Rationale: At 10 weeks, fetal movement is unlikely to be felt. The nurse should ask the client to describe what she felt to determine if it was indeed fetal movement or another sensation.
A pregnant patient at 30 weeks gestation reports lower back pain and difficulty sleeping. Which of the following is the most appropriate recommendation for the nurse to make?
- A. Rest in bed with your legs elevated to reduce back pain.
- B. Use a firm mattress and avoid sleeping on your back.
- C. Take over-the-counter pain medications as prescribed to alleviate pain.
- D. Perform light stretching exercises before bed to relieve discomfort.
Correct Answer: B
Rationale: The correct answer is B. Using a firm mattress and avoiding sleeping on the back is the most appropriate recommendation for a pregnant patient at 30 weeks gestation experiencing lower back pain. Here's why:
1. Firm mattress provides better support for the back and helps maintain proper spinal alignment during sleep.
2. Avoiding sleeping on the back reduces pressure on the major blood vessels, preventing potential complications like supine hypotensive syndrome.
3. Resting in bed with legs elevated (choice A) may not address the root cause of back pain and may not be recommended for extended periods during pregnancy.
4. Taking over-the-counter pain medications (choice C) should be avoided unless prescribed by a healthcare provider due to potential risks to the fetus.
5. Performing light stretching exercises (choice D) can be beneficial, but avoiding certain positions like lying on the back is more crucial for back pain relief during pregnancy.
Which of the following is true about the use of a birthing ball during labor?
- A. It is contraindicated for patients with high blood pressure
- B. It promotes pelvic mobility and can help reduce pain
- C. It should only be used during the second stage of labor
- D. It is only effective in early labor
Correct Answer: B
Rationale: The correct answer is B because a birthing ball promotes pelvic mobility, which can help reduce pain during labor by encouraging movement and optimal positioning of the baby. It is not contraindicated for patients with high blood pressure unless specifically advised by a healthcare provider. It can be used throughout labor, not just during the second stage, and is effective at various stages, not just in early labor.
