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: During pregnancy, it is important to be aware of danger signs that warrant contacting the healthcare provider. Puffiness of the face, especially around the eyes, can indicate a serious condition like preeclampsia. Other danger signs include vaginal bleeding, rupture of membranes, severe abdominal pain, visual disturbances, persistent vomiting, and changes in fetal movements. Morning sickness, breast tenderness, and urinary frequency are common symptoms of pregnancy and are not typically concerning unless they become severe or persistent, and do not usually require immediate medical attention.

Correct Answer: B

Rationale: When late decelerations are noted on the fetal heart rate (FHR) monitor during oxytocin infusion, it indicates decreased oxygenation to the fetus. The immediate action the nurse should take is to stop the oxytocin infusion. This helps reduce uterine activity, increase fetal oxygenation, and prevent further stress on the fetus. Stopping the oxytocin infusion is crucial to address the underlying issue causing the late decelerations. Checking the woman's blood pressure and pulse, increasing the IV rate of the nonadditive solution, or notifying the healthcare provider can be important actions but are secondary to stopping the oxytocin infusion in this scenario.

Correct Answer: D

Rationale: To assess tactile (vocal) fremitus, the nurse palpates the thorax and compares vibrations from side to side as the client repeats the word 'ninety-nine.' This technique helps in evaluating the intensity and symmetry of vibrations felt. Palpating for symmetric chest expansion involves assessing the expansion of the chest during breathing by placing hands on the anterolateral wall. Auscultating the breath sounds over the trachea and larynx is done to assess bronchial breath sounds, while auscultating over the peripheral lung fields is used to assess vesicular breath sounds.

Correct Answer: B

Rationale: The Romberg test is a balance assessment that evaluates cerebellar function. During the test, the client stands with feet together and eyes closed, aiming to maintain balance for about 20 seconds. This test helps identify issues related to balance and proprioception, not hearing acuity or sound discrimination. Choices C and D are incorrect as the Romberg test focuses on balance, not distant hearing or sound discrimination.
