Correct Answer: B

Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.

Correct Answer: A

Rationale: When a nurse notes accelerations from the baseline rate of the fetal heart rate, particularly when they occur with fetal movement, it is considered a reassuring sign. This indicates a healthy response to fetal activity. Reassuring signs in FHR monitoring include an average rate between 120 and 160 beats/min at term, a regular rhythm with slight fluctuations, accelerations from the baseline rate (often associated with fetal movement), and the absence of decreases from the baseline rate. Choices B, C, and D are incorrect because accelerations in FHR with fetal movement are not indicative of the need to contact the physician, fetal distress, or a nonreassuring sign. These signs would typically be associated with other abnormal FHR patterns that would warrant further assessment and intervention.

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: B

Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.

Correct Answer: B

Rationale: Nagele's rule is a method used to estimate the date of delivery for pregnant clients. The rule involves subtracting 3 months and adding 7 days to the date of the first day of the last normal menstrual period, then adjusting the year. Subtracting 3 months from August 30, 2013, brings the date to May 30, 2013; adding 7 days results in June 6, 2013. Finally, after correcting the year, the estimated date of delivery is June 6, 2014. Therefore, the correct answer is June 6, 2014. Choices A, C, and D are incorrect because they do not follow the accurate calculation based on Nagele's rule.
