A client presents to Labor & Delivery for an ultrasound at 16 weeks gestation for vaginal bleeding. She asks the nurse if the procedure will harm her baby. Which is appropriate for the nurse to tell the client?

Correct Answer: B

Rationale: The correct answer is B: "Ultrasounds use sound waves to view your baby, not radiation, so the procedure will not harm your baby." Rationale: 1. Ultrasound uses sound waves, not radiation, to create images of the baby in the womb. 2. The sound waves are considered safe for both the mother and the developing baby. 3. There is no evidence to suggest that ultrasound procedures pose any harm to the pregnancy. 4. It is important to reassure the client that the ultrasound is a routine procedure and will not harm the baby. Summary: Choice A is incorrect because it wrongly implies that the ultrasound could potentially harm the baby due to the existing bleeding, which is not true. Choice C is incorrect as it does not provide specific information regarding the safety of ultrasound during pregnancy. Choice D is incorrect as it lacks the specific information about the safety of ultrasound and relies on a general statement about the doctor's intentions.

Correct Answer: A

Rationale: Correct Answer: A - Rupture of membranes Rationale: 1. Rupture of membranes is necessary for the insertion of intrauterine pressure catheter and fetal spiral electrode. 2. It allows safe passage of the catheter and electrode into the uterus. 3. Without ruptured membranes, there is a risk of infection and difficulty in inserting the devices. Summary: - Choice B (Dilated cervix) is not required for the insertion of these devices. - Choice C (Vertex fetus) is not a factor in the insertion process. - Choice D (Moderate variability) is related to fetal heart rate monitoring, not device insertion.

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.
