Which finding indicates potential hyperemesis gravidarum in a client who is 11 weeks pregnant?

The presence of ketonuria is a significant indication of hyperemesis gravidarum, especially in a client who is 11 weeks pregnant. Hyperemesis gravidarum is characterized by severe nausea and vomiting that can lead to dehydration, electrolyte imbalances, and weight loss. When the body experiences prolonged vomiting and cannot maintain proper hydration and nutrition, it may begin to break down fats for energy. This fat metabolism produces ketones, which can be detected in the urine.

Ketonuria suggests that the body is in a state of starvation or is not receiving enough carbohydrates, which can occur in the context of severe hyperemesis gravidarum. In contrast, other symptoms like weight gain would not be expected in this condition, and while fatigue and headaches can occur for various reasons during pregnancy, they are not specific indicators of hyperemesis gravidarum. Thus, the presence of ketones in the urine is a distinct marker that warrants further evaluation and management of the client's condition.
