The practical nurse (PN) tells a pregnant client not to eat if she is in labor. Which is the most important reason for this nursing intervention?

A. Nausea occurs at the onset of labor: Nausea may occur but is not the primary reason for NPO status. B. Emptying time of the stomach is increased in labor: True, but the main concern is aspiration risk. C. Blood is shunted from the gut during labor: Not the major factor for NPO order. D. There is increased risk of aspiration of emesis: During labor, anesthesia may be required; delayed gastric emptying increases aspiration risk if vomiting occurs under sedation.
