The nurse is caring for a 45-year-old client who is scheduled to have a chorionic villus sampling. Which information is most important for the nurse to obtain from the client before the procedure?

Correct Answer: D

Rationale: The correct answer is D: Maternal bleeding disorders. This information is crucial before a chorionic villus sampling to assess the risk of excessive bleeding during the procedure due to potential clotting issues. Maternal bleeding disorders can increase the risk of complications during the procedure. A: NPO status is not as critical for this procedure as it does not typically require fasting. B: Blood type and Rh are important for other purposes but not specifically needed before a chorionic villus sampling. C: Weeks of gestation is important for determining the timing of the procedure but does not directly impact the safety or success of the procedure.

Correct Answer: D

Rationale: The correct answer is D because Tums or Rolaids are safe antacids commonly recommended for heartburn during pregnancy. They help neutralize stomach acid and provide relief. Choice A is incorrect as drinking fluids before bedtime can aggravate heartburn. Choice B is incorrect because it's important to eat small, frequent meals to prevent heartburn. Choice C is incorrect as coffee and orange juice can trigger heartburn due to their acidity. Overall, using antacids under healthcare provider guidance is the best option for managing heartburn during pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Rest often with the feet elevated. Elevating the feet helps to promote venous blood flow back to the heart, reducing the risk of venous stasis. When the legs are elevated, gravity assists in returning the blood to the heart. Sitting with the legs crossed (choice A) can actually impede blood flow. Sleeping with the foot of the bed elevated (choice C) may not be as effective as regularly elevating the feet throughout the day. Wearing elastic stockings in the afternoon (choice D) can provide some support but may not be as effective as elevating the feet.

Correct Answer: C

Rationale: The fundal height at 20 weeks gestation should be at the level of the umbilicus. When it is palpated 3 cm below the umbilicus, it is considered lower than normal for gestational age. This finding suggests possible fetal growth restriction or incorrect dating of the pregnancy. It is crucial to monitor closely for fetal well-being and growth. Choice A is incorrect because being 3 cm below the umbilicus is not appropriate for gestational age. Choice B is incorrect as it does not necessarily indicate impending complications, but rather a need for further evaluation. Choice D is incorrect as a fundus higher than normal for gestational age would suggest a larger-than-expected fetus or multiple gestation.

Correct Answer: C

Rationale: The correct answer is C. Observation of posture and body mechanics is essential in assessing lower back pain in a pregnant patient to identify any potential causes related to the growing uterus and changes in body mechanics. Palpation of the lumbar spine (Choice A) may provide some information but does not address the underlying issue. Exercise pattern and duration (Choice B) are important but not the priority in this scenario. Ability to sleep for at least 6 hours uninterrupted (Choice D) is not directly related to assessing lower back pain.
