A nurse is assisting a laboring person with a vacuum extraction. What is the most important nursing action to ensure a safe procedure?
- A. monitor fetal heart rate continuously
- B. prepare the person for a cesarean section
- C. monitor for signs of uterine rupture
- D. assist with positioning the person
Correct Answer: B
Rationale: The correct answer is B: prepare the person for a cesarean section. In the scenario of vacuum extraction, if there are complications or the procedure is unsuccessful, the person may need to undergo an emergency cesarean section. By preparing the person for this possibility, the nurse ensures timely intervention if needed, prioritizing the safety of both the person and the baby. Monitoring fetal heart rate continuously (A) is important but not the most crucial action in this case. Monitoring for signs of uterine rupture (C) is not directly related to vacuum extraction. Assisting with positioning (D) is important but not as critical as preparing for a potential cesarean section.
What factor should the nurse consider when counseling a Chinese immigrant?
- A. Many Chinese eat little protein
- B. Many Chinese believe in eating cold foods
- C. Many Chinese are prone to anemia
- D. Many Chinese believe strawberries cause birth defects
Correct Answer: D
Rationale: Cultural beliefs, such as the idea that strawberries might cause birth defects, should be considered to provide culturally sensitive care.
The nurse is educating a pregnant patient about the signs of preterm labor. Which of the following should the nurse include in the teaching plan?
- A. Frequent, regular contractions every 10 minutes or less.
- B. Decreased fetal movement and back pain.
- C. Mild cramping and occasional vaginal spotting.
- D. Headaches and blurred vision, especially after physical activity.
Correct Answer: A
Rationale: Step 1: Frequent, regular contractions every 10 minutes or less are a key sign of preterm labor, indicating the uterus is contracting and potentially dilating prematurely.
Step 2: This pattern of contractions can lead to preterm delivery and requires immediate medical attention to prevent complications for both the mother and the baby.
Step 3: Decreased fetal movement and back pain (Option B) are not specific signs of preterm labor but can indicate other issues that need evaluation.
Step 4: Mild cramping and occasional vaginal spotting (Option C) can be normal in pregnancy and may not always indicate preterm labor.
Step 5: Headaches and blurred vision (Option D) are more indicative of conditions like preeclampsia rather than preterm labor.
A pregnant patient is at 32 weeks gestation and reports that she feels short of breath when lying flat. What should the nurse's priority action be?
- A. Assess the patient's respiratory rate and oxygen saturation.
- B. Encourage the patient to sit up and rest in a more upright position.
- C. Ask the patient to perform deep breathing exercises to improve oxygen flow.
- D. Instruct the patient to take shallow breaths and avoid exertion.
Correct Answer: B
Rationale: The correct answer is B: Encourage the patient to sit up and rest in a more upright position. This is the priority action because it helps relieve pressure on the diaphragm and allows for better lung expansion, improving oxygenation for the pregnant patient experiencing shortness of breath. Sitting upright also reduces the risk of supine hypotensive syndrome by improving blood flow to the placenta.
Assessing respiratory rate and oxygen saturation (Choice A) may be important but should come after the patient is in a more comfortable position. Deep breathing exercises (Choice C) may not address the immediate relief needed for the patient. Instructing the patient to take shallow breaths (Choice D) may worsen the situation by limiting oxygen intake and exacerbating respiratory distress.
A pregnant patient at 36 weeks gestation reports feeling more tired than usual. What is the nurse's priority action?
- A. Encourage the patient to get more rest and limit physical activity.
- B. Assess the patient for signs of anemia or other complications.
- C. Administer iron supplements to improve energy levels.
- D. Instruct the patient to increase caloric intake to meet energy demands.
Correct Answer: B
Rationale: The correct answer is B. Assess the patient for signs of anemia or other complications. At 36 weeks gestation, fatigue can be a sign of anemia, a common issue in pregnancy. Anemia can lead to complications for both the mother and the baby, so assessing for this is crucial. Encouraging rest (choice A) may help with fatigue temporarily but does not address the underlying cause. Administering iron supplements (choice C) without assessing first can be harmful if anemia is not the issue. Instructing the patient to increase caloric intake (choice D) is not the priority as it does not address the potential medical issue causing the fatigue.
