Which occurrence is related to cervical dilation and effacement?

Choice A rationale
While iron-rich foods are important, the decrease in hematocrit is primarily due to hemodilution rather than inadequate iron intake. Hemodilution occurs as plasma volume increases more than red cell mass.
Choice B rationale
Hematocrit changes in pregnancy are typically not indicative of a serious problem but a normal physiological adaptation. Hemodilution reduces hematocrit without indicating a pathological condition.
Choice C rationale
During pregnancy, plasma volume increases by approximately 50%, while red cell mass increases by about 30%, leading to hemodilution. This physiological change results in a lower hematocrit value.
Choice D rationale
Although hematocrit decreases due to hemodilution, it does not mean that there is a deficiency in red blood cell production. It reflects the dilution effect of increased plasma volume during pregnancy.

Choice A rationale
Continuing the same comfort methods that have become ineffective is unlikely to help the client and may increase frustration. Adaptation to the client’s changing needs is necessary for effective care.
Choice B rationale
Choosing an alternate method of comfort promotion is appropriate as it addresses the client's current needs and helps to alleviate frustration. Alternate methods might include massage, repositioning, or hydrotherapy.
Choice C rationale
Asking the support person to leave the room may not address the client's comfort needs and could decrease her emotional support, potentially increasing stress and frustration rather than providing relief.
Choice D rationale
Telling the client to relax more is not supportive and does not provide a new strategy to promote comfort. It may be dismissive and can increase the client’s frustration and anxiety during labor.
