The licensed practical nurse (LPN) on the nursing team has notified Nina the New Nurse that a client with cardiomyopathy is complaining of feeling a period of dizziness while ambulating to the bathroom this morning. After assessing the client, Nina the New Nurse compares the blood pressure and heart rate to the vitals taken four hours earlier and determines a decrease in systolic blood pressure (from 150 to 115 mmHG) and increased heart rate (from 78 to 98). Based on her findings, what should Nina the New Nurse instruct the LPN to do?
