In patients with severe diabetes insipidus the water deprivation test can be diagnostic. However, it can also be risky; if the patient loses more than 3% of body weight, cardiovascular collapse and shock can occur. This patient has lost 5% of initial body weight, so the professional should stop the test. Administering salt tablets does not take priority over stopping the test. Glucose measurement is not relevant.
