The nurse caring for the laboring woman should know that meconium is produced by:

Choice A rationale
Quickening, the first fetal movements felt by the mother, typically occurs between 16 and 20 weeks of gestation, so she should expect to feel fluttering sensations within the next month.
Choice B rationale
At 15 weeks of gestation, it is too early for most first-time mothers to feel fetal movements. Quickening usually occurs between 16 and 20 weeks, so she has not missed the window.
Choice C rationale
While some fetal movements may be subtle, it is inaccurate to suggest that some babies are entirely quiet. Quickening is generally felt by most mothers between 16 and 20 weeks.
Choice D rationale
The baby is indeed moving, but fetal movements are usually not felt until 16 to 20 weeks of gestation in first-time pregnancies, so it is normal not to feel them yet at 15 weeks.

Choice A rationale
Limited perception of bladder fullness can occur with epidural anesthesia, but it is not the most common or harmful complication. Patients should be monitored for urinary retention.
Choice B rationale
Severe afterbirth headache, or post-dural puncture headache, can result from epidural complications, but it is less common than hypotension.
Choice C rationale
Hypotension is the most common and potentially harmful complication of epidural anesthesia. It occurs due to sympathetic nerve blockade, leading to vasodilation and decreased cardiac output. Normal blood pressure ranges: systolic 90-120 mmHg, diastolic 60-80 mmHg.
Choice D rationale
Increased respiratory rate is not a common complication of epidural anesthesia. It is more likely related to anxiety or other factors and should be monitored accordingly.
