A pregnant patient at 26 weeks gestation reports frequent headaches and blurred vision. What should the nurse do first?
- A. Encourage the patient to take over-the-counter pain medication for relief.
- B. Monitor the patient's blood pressure and check for signs of preeclampsia.
- C. Advise the patient to rest and stay hydrated to alleviate symptoms.
- D. Schedule a follow-up appointment for further evaluation in a few days.
Correct Answer: B
Rationale: The correct answer is B: Monitor the patient's blood pressure and check for signs of preeclampsia. At 26 weeks gestation, headaches and blurred vision could be symptoms of preeclampsia, a serious condition in pregnancy. Monitoring blood pressure is crucial as high blood pressure is a key indicator. Preeclampsia can lead to severe complications for both the mother and baby if left untreated. Encouraging over-the-counter pain medication (Choice A) may mask symptoms without addressing the underlying cause. Rest and hydration (Choice C) are important, but immediate evaluation for preeclampsia is necessary. Scheduling a follow-up appointment (Choice D) delays potential diagnosis and treatment.
A nurse is working in the prenatal clinic. Which of the following findings seen in third-trimester pregnant women would the nurse consider to be within normal limits?
- A. Leg cramps.
- B. Varicose veins.
- C. Hemorrhoids.
- D. Fainting spells.
Correct Answer: A
Rationale: Leg cramps, varicose veins, and hemorrhoids are common complaints during pregnancy due to increased blood volume and pressure on the lower extremities. Fainting spells are not considered normal and may indicate an underlying issue.
A pregnant patient at 36 weeks gestation reports difficulty breathing when lying flat. What should the nurse do first?
- A. Encourage the patient to rest in a semi-reclined position or on her left side.
- B. Administer oxygen as prescribed to improve oxygenation.
- C. Monitor the fetal heart rate and assess for signs of distress.
- D. Instruct the patient to take shallow breaths and stay in bed.
Correct Answer: A
Rationale: The correct answer is A because positioning the patient in a semi-reclined or left side position can alleviate pressure on the diaphragm and improve breathing. This position helps optimize blood flow to the uterus and placenta. Encouraging rest in this position can improve oxygenation for both the mother and fetus. Administering oxygen (Choice B) may help with oxygenation but does not address the underlying issue of positional discomfort. Monitoring fetal heart rate (Choice C) is important but not the first action to address the mother's breathing difficulty. Instructing the patient to take shallow breaths and stay in bed (Choice D) does not address the positional component of the issue.
The nurse is caring for a patient who is in labor with her first child. The patient's mother is present for support and notes that things have changed in the delivery room since she last gave birth in the early 1980s. Which current trend or intervention may the patient's mother find most different?
- A. Fetal monitoring throughout labor
- B. Postpartum stay of 10 days
- C. Expectant partner and family in operating room for cesarean birth
- D. Hospital support for breastfeeding
Correct Answer: D
Rationale: 1. The correct answer is D: Hospital support for breastfeeding. This is the most different trend compared to the early 1980s.
2. In the past, breastfeeding support in hospitals was minimal, but now it is a standard practice to provide education and assistance.
3. Fetal monitoring throughout labor (A) has been a common practice for many years and is not a recent trend.
4. Postpartum stay of 10 days (B) is excessive; postpartum stays have actually become shorter over time.
5. Having expectant partners and family in the operating room for cesarean birth (C) is a more recent practice but has become increasingly common in recent years.
Which statement about fetal circulation is correct?
- A. The foramen ovale is between ventricles
- B. Umbilical vein contains oxygen-poor blood
- C. Right atrium contains mixed blood
- D. Ductus venosus lies between aorta and pulmonary artery
Correct Answer: C
Rationale: The right atrium contains both oxygen-rich and oxygen-poor blood due to the unique fetal circulatory system.
