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. Calcium supplements are not used to treat dehydration; fluid replacement is the appropriate intervention. B. Dehydration can trigger the release of antidiuretic hormone (ADH) and oxytocin, which can stimulate uterine contractions and increase the risk for preterm labor. Encouraging adequate oral or IV hydration helps suppress contractions and maintain uterine quiescence. C. Dehydration does not directly cause decreased hemoglobin or hematocrit; in fact, dehydration can cause hemoconcentration, leading to increased hemoglobin and hematocrit values. D. While dehydration may worsen some gastrointestinal symptoms, it is not causally associated with gastroesophageal reflux.
