The patient should absolutely measure their temperature in the morning and the evening. In order to do this, it is enough to hold the thermometer under the tongue for 4 to 5 minutes. In the case of body temperature higher than 37.5, this should certainly be reported to the doctor. Patients with hypertension should absolutely measure their blood pressure in the morning and the evening, recording their measurements into a chart, which they should present to their doctors every time they visit for a follow-up examination. Particularly during the first few weeks after surgery, daily urine output and weight measurements should certainly be monitored. How to make these measurements is shown to the patients during their stay at the hospital by their doctors and health workers.
