A nurse is caring for a client who has hyperemesis gravidarum. Which of the following laboratory tests should the nurse anticipate?
Correct Answer: A
Rationale: Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. One important laboratory test that the nurse should anticipate for a client with hyperemesis gravidarum is the urine ketones test. Ketones in the urine can indicate that the body is breaking down fat for energy instead of using glucose, which can occur during prolonged fasting or in conditions like hyperemesis gravidarum where there is severe vomiting leading to inadequate intake of nutrients. Monitoring urine ketones levels helps healthcare providers assess the severity of dehydration and metabolic derangement in these patients. It guides the management of fluid and electrolyte replacement to prevent complications like ketosis and metabolic acidosis.
