An amniocentesis is scheduled for a pregnant client in the third trimester. The nurse informs the client that the most common indication for amniocentesis during the third trimester is for which reason?
- A. Determination of whether alpha-fetoprotein (AFP) is present in the amniotic fluid
- B. Checking the amniotic fluid for intrauterine infection
- C. Determination of fetal lung maturity
- D. Checking the fetal cells for chromosomal abnormalities
Correct Answer: C
Rationale: The most common indication for amniocentesis in the third trimester is the determination of fetal lung maturity. This assessment is essential to evaluate the fetus's readiness for extrauterine life. Checking for alpha-fetoprotein (AFP) in the amniotic fluid is more commonly associated with midtrimester amniocentesis to identify chromosomal abnormalities. Assessing for intrauterine infection is not a primary reason for amniocentesis in the third trimester. While checking fetal cells for chromosomal abnormalities is a common indication for midtrimester amniocentesis, it is not the most common indication in the third trimester.

Immediately after delivery, the nurse assesses the woman's uterine fundus. At what location does the nurse expect to be able to palpate the fundus?
- A. At the level of the umbilicus
- B. Two centimeters above the umbilicus
- C. Midway between the symphysis pubis and umbilicus
- D. In the pelvic cavity
Correct Answer: C
Rationale: The correct answer is midway between the symphysis pubis and the umbilicus. Immediately after delivery, the uterus is about the size of a large grapefruit or softball. The fundus can be palpated at this location but then rises to a level just above the umbilicus before sinking to the level of the umbilicus, where it remains for about 24 hours. After 24 hours, the fundus starts descending gradually. By the 10th to 14th day, the fundus is in the pelvic cavity and cannot be palpated abdominally. Choices A and B are incorrect as the fundus is not initially at the level of the umbilicus or 2 centimeters above it. Choice D is also incorrect as the fundus does not remain in the pelvic cavity immediately after delivery.
When determining a fetal heart rate (FHR) and noting accelerations from the baseline rate when the fetus is moving, a nurse interprets this finding as:
- A. A reassuring sign
- B. An indication of the need to contact the physician
- C. An indication of fetal distress
- D. A nonreassuring sign
Correct Answer: A
Rationale: When a nurse notes accelerations from the baseline rate of the fetal heart rate, particularly when they occur with fetal movement, it is considered a reassuring sign. This indicates a healthy response to fetal activity. Reassuring signs in FHR monitoring include an average rate between 120 and 160 beats/min at term, a regular rhythm with slight fluctuations, accelerations from the baseline rate (often associated with fetal movement), and the absence of decreases from the baseline rate. Choices B, C, and D are incorrect because accelerations in FHR with fetal movement are not indicative of the need to contact the physician, fetal distress, or a nonreassuring sign. These signs would typically be associated with other abnormal FHR patterns that would warrant further assessment and intervention.
When preparing to listen to a client's breath sounds, what technique should a nurse use?
- A. Ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap.
- B. Listen to the right lung first, then the left lung, moving from top to bottom systematically.
- C. Ask the client to take deep breaths through the mouth.
- D. Use the diaphragm of the stethoscope, holding it firmly against the client's chest.
Correct Answer: D
Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.
When a client who is having trouble conceiving says to the nurse, 'I have started taking ginseng,' the best response by the nurse is:
- A. "There is some evidence that ginseng may enhance in vitro sperm motility."?
- B. "Some studies show that ginseng enhances in vitro sperm motility."?
- C. "Ginseng is not proven to be effective for infertility; have you considered other options?"?
- D. "It's probably not going to hurt you, but it's also probably not going to help. Let's look at some other alternatives."?
Correct Answer: B
Rationale: Some studies have shown that ginseng enhances in vitro sperm motility, making Choice B the correct response. It directly addresses the client's comments about taking ginseng and provides valuable information regarding its potential effect on sperm motility. Alternative therapies are often sought by couples struggling with infertility, and acknowledging the potential benefits of ginseng can empower the client. Choice A is incorrect as it slightly misrepresents the evidence by overgeneralizing its effectiveness. Choice C dismisses ginseng without acknowledging its potential benefits, potentially closing off a fruitful discussion with the client. Choice D, while neutral, misses the opportunity to validate the client's choice and explore further options collaboratively. It is crucial for nurses to respect clients' choices, provide accurate information, and guide them effectively in exploring different alternatives.
A woman is receiving oxytocin to induce labor. Which action should the nurse take first upon noting the presence of late decelerations on the fetal heart rate (FHR) monitor?
- A. Notifying the healthcare provider
- B. Stopping the oxytocin infusion
- C. Checking the woman's blood pressure and pulse
- D. Increasing the intravenous (IV) rate of the nonadditive solution
Correct Answer: B
Rationale: When late decelerations are noted on the fetal heart rate (FHR) monitor during oxytocin infusion, it indicates decreased oxygenation to the fetus. The immediate action the nurse should take is to stop the oxytocin infusion. This helps reduce uterine activity, increase fetal oxygenation, and prevent further stress on the fetus. Stopping the oxytocin infusion is crucial to address the underlying issue causing the late decelerations. Checking the woman's blood pressure and pulse, increasing the IV rate of the nonadditive solution, or notifying the healthcare provider can be important actions but are secondary to stopping the oxytocin infusion in this scenario.
