A patient in labor is undergoing an epidural block and is given intravenous fluid. What is the purpose of this?
- A. To treat hypotension that results from hemorrhage
- B. To increase urine output
- C. To treat insensible fluid losses
- D. To treat hypotension that results from sympathetic blockade
Correct Answer: D
Rationale: The correct answer is D: To treat hypotension that results from sympathetic blockade. When an epidural block is administered during labor, sympathetic blockade can lead to a drop in blood pressure. By providing intravenous fluid, the goal is to increase preload and maintain blood pressure to counteract the hypotension caused by sympathetic blockade.
A: Treating hypotension from hemorrhage is not the primary purpose in this scenario.
B: Increasing urine output is not the main goal of giving intravenous fluid during an epidural block.
C: Treating insensible fluid losses is not the immediate concern when a patient is experiencing hypotension from sympathetic blockade.
The nurse is caring for a pregnant patient who has a BMI of 30. Which of the following complications is the patient at increased risk for during pregnancy?
- A. Preeclampsia and gestational diabetes
- B. Hyperemesis gravidarum and miscarriage
- C. Iron-deficiency anemia and urinary tract infections
- D. Gestational hypertension and placenta previa
Correct Answer: A
Rationale: The correct answer is A: Preeclampsia and gestational diabetes. A pregnant patient with a BMI of 30 is considered obese, increasing the risk of developing preeclampsia and gestational diabetes. Obesity is a known risk factor for these complications due to the increased strain on the body's systems. Preeclampsia is characterized by high blood pressure and protein in the urine, which can lead to serious complications for both the mother and the baby. Gestational diabetes is a type of diabetes that develops during pregnancy and can lead to complications for both the mother and the baby if not managed properly. The other choices (B, C, D) are not directly associated with obesity or a BMI of 30 during pregnancy, making them incorrect.
What is the priority intervention for a laboring person with a suspected uterine rupture?
- A. prepare for an emergency cesarean section
- B. perform uterine massage
- C. apply pressure to the abdomen
- D. monitor the fetal heart rate continuously
Correct Answer: B
Rationale: The correct answer is B: perform uterine massage. This intervention aims to prevent excessive bleeding and stabilize the uterus. Uterine massage helps to maintain uterine tone, which is crucial in managing uterine rupture. This intervention can help reduce the risk of maternal hemorrhage and improve fetal oxygenation.
Incorrect choices:
A: Emergency cesarean section may be necessary but is not the priority as immediate measures to control bleeding and maintain uterine tone are crucial.
C: Applying pressure to the abdomen is not recommended as it can further exacerbate uterine rupture and increase the risk of complications.
D: Continuous monitoring of the fetal heart rate is important but not the priority in managing uterine rupture, which requires immediate intervention to prevent maternal and fetal complications.
A couple is preparing to interview obstetric primary care providers to determine who they will go to for care during their pregnancy and delivery.
- A. Take a tour of hospital delivery areas.
- B. Develop a preliminary birth plan.
- C. Make appointments with three or four obstetric care providers.
- D. Search the Internet for the malpractice histories of the providers.
Correct Answer: B
Rationale: Developing a preliminary birth plan helps couples clarify their preferences and priorities, facilitating better communication with potential providers.
A nurse is educating a pregnant patient about warning signs to report during pregnancy. Which of the following statements indicates that the teaching has been effective?
- A. I should report any sudden increase in swelling, especially in my hands and face.
- B. I should wait until after my due date to report any concerns.
- C. I should only report changes in fetal movement after the third trimester.
- D. I don't need to report headaches or blurry vision unless they are severe.
Correct Answer: A
Rationale: The correct answer is A because sudden increase in swelling, especially in hands and face, can indicate preeclampsia, a serious condition during pregnancy. Swelling in these areas can be a sign of fluid retention and increased blood pressure. Prompt reporting and intervention are crucial to prevent complications for both the mother and the baby.
Choices B, C, and D are incorrect because:
B: Waiting until after the due date to report concerns can lead to missed opportunities for early intervention and can be dangerous for both the mother and the baby.
C: Changes in fetal movement should be reported immediately, not just after the third trimester, as they can indicate fetal distress.
D: Headaches and blurry vision, even if not severe, can be symptoms of preeclampsia or other serious conditions that require immediate attention. Waiting for symptoms to worsen can be harmful.
