Final answer:
Dehydration is the subject of this question. Bulimia can contribute to dehydration through frequent vomiting and fluid loss.
Step-by-step explanation:
The patient in question is experiencing dehydration. Dehydration is a condition where the body lacks sufficient fluid. Symptoms of dehydration can include thirst, confusion, and changes in blood pressure. In this case, the patient's blood pressure of 70/45 and complaint of thirst indicate dehydration.
Bulimia, the condition for which the patient was admitted to the hospital, can contribute to dehydration. Frequent vomiting, which is characteristic of bulimia, can lead to fluid loss and electrolyte imbalances, resulting in symptoms of dehydration.
