The nurse is preparing to assist with the insertion of an intrauterine pressure catheter and a fetal spiral electrode. What is required for proper placement by the practitioner? Select all that apply.

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: 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.

Correct Answer: D

Rationale: The correct answer is D: "If you are traveling by car, stop to walk every 1 to 2 hours." This is the best advice because it promotes circulation and reduces the risk of blood clots during long car rides. Walking helps prevent stiffness and discomfort. A: "Only travel by car during pregnancy" is incorrect because other modes of transportation can be safe as well. B: "Avoid use of the seat belt during the third trimester" is incorrect as wearing a seat belt is crucial for the safety of both the mother and the baby in case of an accident. C: "You can travel by plane until your 38th week of gestation" is incorrect as most airlines have restrictions on flying after 36 weeks due to the risk of preterm labor.
