Correct Answer: D

Rationale: To assess vesicular breath sounds, the nurse should place the stethoscope over the peripheral lung fields. Vesicular breath sounds are heard in these areas where air flows through the smaller bronchioles and alveoli. Bronchovesicular breath sounds, not vesicular, are heard over the major bronchi. Bronchial (tracheal) breath sounds are heard over the trachea and larynx, not vesicular sounds. Breath sounds are not heard over the xiphoid process, making it an incorrect choice.

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.

Correct Answer: B

Rationale: A rubella titer of less than 1:8 indicates that the client is not immune to rubella. In such cases, retesting will be necessary during the pregnancy. If the client is found to be non-immune, rubella immunization is required post-delivery. Therefore, choices A, C, and D are incorrect. Choice A suggests exposure, which cannot be confirmed by the titer result. Choice C wrongly implies that the client has not developed immunity, which is not accurate. Choice D is incorrect as the titer result is not within the normal immune range.

Correct Answer: A

Rationale: Fetal movements (quickening) are first noticed by multigravida pregnant women at 16 to 20 weeks of gestation and gradually increase in frequency and strength. This is when the mother typically begins to feel the baby's movements. Choices B, C, and D are incorrect because fetal movements are not felt as early as 6, 8, or 12 weeks of gestation. At 6 weeks, the embryo's movements are not yet strong enough to be felt by the mother. By 8 weeks, the movements are still too subtle to be perceived. At 12 weeks, although fetal movements start, they are usually not strong enough to be felt by the mother.

Correct Answer: A

Rationale: When a client seeks information about birth control, it is essential for the nurse to first assess the client's existing knowledge on the subject. This enables the nurse to provide tailored information that complements what the client already knows, facilitating better understanding and decision-making. Providing written material is a helpful educational tool but should not be the first intervention. Offering specific advice on birth control methods based on age and lifestyle limits the client's autonomy and decision-making process. Mentioning the client's boyfriend as a requirement for discussing birth control is inappropriate and nontherapeutic, as the client should be able to seek information independently.
