Final answer:
Evidence of severe preeclampsia in a patient's medical record includes high blood pressure and proteinuria, important signs for the diagnosis of this pregnancy complication.
Step-by-step explanation:
The entries on a patient's medical record that provide evidence of the diagnosis of severe preeclampsia are high blood pressure and proteinuria. Preeclampsia is a pregnancy complication characterized by the onset of high blood pressure and often a significant amount of protein in the urine. While edema (swelling) is also a common sign associated with preeclampsia, it is not considered as specific or critical for diagnosis as the former two signs. Normal liver function would not be evidence of severe preeclampsia, since abnormal liver function tests can sometimes be associated with severe cases of the condition.
