What are the functions of amniotic fluid? (Select all that apply.)
- A. Maintaining an even temperature
- B. Impeding excessive fetal movement
- C. Lubricating fetal skin
- D. Acting as a reservoir for nutrients
Correct Answer: A
Rationale: The amniotic fluid provides maintenance of even temperature; prevents amnion from adhering to fetal skin; allows buoyancy, symmetrical growth, and fetal movement; and acts as a cushion for the fetus. Although the fetus does swallow amniotic fluid, it has no nutritional value. Impeding excessive fetal movement and lubricating fetal skin are not primary functions of amniotic fluid.
A pregnant patient is concerned about the safety of taking over-the-counter (OTC) medications. Which statement by the nurse would be most appropriate?
- A. OTC medications are safe to take without consulting a doctor.
- B. Consult your healthcare provider before taking any OTC medications during pregnancy.
- C. You can take any OTC medication as long as it is for a common pregnancy symptom.
- D. Only prescription medications are safe during pregnancy.
Correct Answer: B
Rationale: The correct answer is B because it emphasizes the importance of consulting a healthcare provider before taking any OTC medications during pregnancy. This is crucial because not all OTC medications are safe during pregnancy, and individual health conditions can affect their safety. Choice A is incorrect because not all OTC medications are safe without consulting a healthcare provider. Choice C is incorrect as it oversimplifies the safety of OTC medications during pregnancy. Choice D is incorrect because not only prescription medications are safe during pregnancy; some OTC medications can also be safe, but it is essential to consult a healthcare provider to ensure safety.
A pregnant patient at 28 weeks gestation expresses concern about her baby's movements. Which of the following should the nurse recommend?
- A. Count fetal movements and report a decrease of more than 10 movements per day.
- B. Wait until after 32 weeks to worry about fetal movement.
- C. Do not count fetal movements and only report if you notice pain.
- D. Always lie down and count fetal movements after meals.
Correct Answer: A
Rationale: The correct answer is A: Count fetal movements and report a decrease of more than 10 movements per day. This recommendation is evidence-based and aligns with guidelines for monitoring fetal well-being. Counting fetal movements helps assess fetal health, and a decrease in movements could indicate potential issues like fetal distress. Reporting a decrease of more than 10 movements per day ensures timely intervention if needed.
Choice B is incorrect because waiting until after 32 weeks could delay necessary intervention if there are concerns about fetal movements. Choice C is incorrect as it dismisses the importance of monitoring fetal movements altogether. Choice D is incorrect as there is no requirement to always lie down or restrict monitoring to only after meals, which could lead to missed opportunities for detecting potential problems.
A nurse is assisting with a vaginal delivery. What is the most important action to take when the fetal head begins to crown?
- A. apply gentle downward pressure
- B. administer pain relief
- C. administer analgesics
- D. perform perineal massage
Correct Answer: A
Rationale: The correct answer is A: apply gentle downward pressure. This action helps prevent the baby from being born too quickly, reducing the risk of tearing for the mother. It also ensures a controlled delivery, decreasing the likelihood of complications such as shoulder dystocia. Administering pain relief (B) or analgesics (C) may be necessary but not the most crucial at this moment. Performing perineal massage (D) is beneficial for reducing the risk of tearing but is not as important as guiding the baby's head during crowning.
The nurse is caring for a pregnant patient at 32 weeks gestation who reports feeling lightheaded and faint when standing. What should the nurse recommend?
- A. Increase fluid intake and avoid standing for long periods.
- B. Take deep breaths and rise quickly from a seated position.
- C. Rest and avoid any physical activity during the day.
- D. Sit upright and avoid bending forward at the waist.
Correct Answer: A
Rationale: The correct answer is A: Increase fluid intake and avoid standing for long periods. This recommendation is appropriate for the patient's symptoms of lightheadedness and fainting, which could be due to dehydration or low blood pressure common in pregnancy. Increasing fluid intake can help maintain adequate blood volume and pressure. Avoiding prolonged standing can prevent pooling of blood in the lower extremities, reducing the risk of dizziness.
Choices B, C, and D are incorrect:
B: Taking deep breaths and rising quickly may worsen symptoms by causing a sudden drop in blood pressure.
C: Complete rest and avoiding physical activity may not address the underlying issue of hydration or blood pressure.
D: Sitting upright and avoiding bending forward may not directly address the need for increased fluid intake and reduced standing time.
