A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

Rationale: A. “Dehydration is treated with calcium supplements.": Calcium supplementation is not a standard treatment for dehydration. Dehydration is primarily managed with fluid replacement, either orally or intravenously, depending on severity. B. "Dehydration is caused by a decreased hemoglobin and hematocrit.": Dehydration often causes increased hemoglobin and hematocrit levels due to hemoconcentration, not a decrease. These lab values are used to assess hydration status but do not cause dehydration. C. "Dehydration is associated with gastroesophageal reflux”: GERD is not a direct cause or result of dehydration. While fluid intake can influence GI symptoms, GERD and dehydration are unrelated conditions with different pathophysiologies. D. "Dehydration can increase the risk for preterm labor”: Dehydration can trigger the release of antidiuretic hormone and oxytocin, both of which may lead to uterine contractions. It is a recognized risk factor for preterm labor and should be addressed promptly.
