A nurse is planning care for a client who is at 16 weeks of gestation and has hyperemesis gravidarum. Which of the following actions should the nurse anticipate taking?

A. Administer a calcium channel blocker. Calcium channel blockers are used primarily for hypertension, angina, and certain cardiac conditions. They are not standard treatment for hyperemesis gravidarum, which is managed with fluid replacement, antiemetics, and nutritional support to prevent dehydration and electrolyte imbalances. B. Encourage foods that are low in proteins. Protein intake is essential for fetal growth and maternal health. Clients with hyperemesis gravidarum may tolerate small, frequent meals with bland, high-protein foods better than low-protein options. Avoiding protein is not a recommended intervention, as it does not reduce nausea and may contribute to nutritional deficiencies. C. Monitor for glycosuria. While glycosuria can occur during pregnancy, it is more relevant in the assessment of gestational diabetes rather than hyperemesis gravidarum. The primary concern in hyperemesis gravidarum is dehydration and electrolyte imbalances rather than glycosuria. D. Monitor IV fluid therapy. Clients with hyperemesis gravidarum often experience severe nausea and vomiting, leading to dehydration and electrolyte imbalances. IV fluid therapy is a critical intervention to restore hydration, correct electrolyte imbalances, and prevent complications such as ketonuria and hypotension.
