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. Gastroesophageal reflux is related to relaxation of the lower esophageal sphincter and increased intra-abdominal pressure during pregnancy, not dehydration. While reflux is common in pregnancy, it is not caused by dehydration or directly linked to preterm contractions. B. Dehydration does not result from decreased hemoglobin and hematocrit. In fact, dehydration typically leads to hemoconcentration, which can cause elevated hemoglobin and hematocrit levels due to reduced plasma volume. C. Dehydration can lead to uterine irritability and increase the frequency of preterm contractions. Reduced circulating volume may stimulate the release of antidiuretic hormone and oxytocin, which can contribute to uterine activity. Therefore, adequate hydration is an important intervention in managing preterm contractions. D. Dehydration is treated with oral or intravenous fluids, not calcium supplementation. While calcium plays a role in muscle contraction, it is not used to correct fluid volume deficits or manage dehydration-related uterine irritability.
