Correct Answer: D

Rationale: The acoustic vibration device is utilized during a nonstress test to awaken a sleeping fetus. This action helps ensure more accurate test results by eliciting fetal movements and heart rate accelerations, which are indicators of fetal well-being. Choices A, B, and C are incorrect because the primary purpose of the acoustic vibration device during a nonstress test is not to stimulate uterine contractions, decrease uterine contractions, or lull the fetus to sleep. Instead, it is specifically used to awaken a sleeping fetus to assess fetal well-being.

Correct Answer: D

Rationale: A contraction stress test (CST) is performed to assess how the fetus responds to the stress of contractions. Indications for this test include decreased fetal movement, intrauterine growth restriction (IUGR), and postmaturity. These conditions may warrant the need for a CST to evaluate fetal well-being and determine appropriate management. Therefore, all of the above options are correct indications for a contraction stress test. Options A, B, and C are incorrect because they are all valid reasons for performing a CST in a pregnant client.

Correct Answer: D

Rationale: The correct answer is D: All of the Above. Multiple risk factors can contribute to preterm labor, including urinary tract infection, multifetal pregnancy, and oligohydramnios. These factors can lead to the uterus being irritated or overstimulated, potentially triggering early labor. Urinary tract infections can cause inflammation and contractions, multifetal pregnancies have a higher risk of preterm labor due to increased uterine stretching, and oligohydramnios can lead to poor fetal growth and premature contractions. Therefore, clients presenting with these conditions require close monitoring and management to prevent preterm birth. Choices A, B, and C are all correct risk factors for preterm labor, making option D the correct answer.

Correct Answer: D

Rationale: Severe shoulder pain is a common finding in clients with a ruptured ectopic pregnancy due to referred pain from diaphragmatic irritation caused by blood in the abdominal cavity. This pain is known as Kehr's sign and is often experienced in the shoulder due to irritation of the phrenic nerve. Choices A, B, and C are incorrect. A ruptured ectopic pregnancy typically presents with symptoms such as abdominal pain, vaginal bleeding, and signs of shock, rather than no alteration in menses, a fetus in the uterus, or elevated blood progesterone levels.

Correct Answer: C

Rationale: During labor, effective pain management is crucial. The nurse should assist the client with patterned breathing techniques to help manage pain and administer opioid analgesic medication as ordered. Providing ice chips is a comfort measure but does not directly address pain relief. Inserting a urinary catheter is not typically indicated at this stage of labor unless there are specific medical indications, such as the need to closely monitor urine output. Therefore, the correct action for the nurse to prepare to take in this scenario is to administer opioid analgesic medication.
