Final answer:
In a patient with end stage renal disease, the PT should expect to see a decrease in systolic blood pressure due to anemia and the body's compromised ability to regulate blood volume.
Step-by-step explanation:
The patient in the scenario described is suffering from end stage renal disease (ESRD). The physical therapist (PT) notices symptoms such as skin pallor, fatigue, and dyspnea which are indicative of anemia, a common complication of ESRD due to decreased synthesis of erythropoietin (EPO). In terms of vital signs, the PT should expect to see a decrease in systolic blood pressure (SBP) in response to the body's compromised blood volume regulation and potential fluid overload. Comprehensive management of ESRD requires careful monitoring of vital signs and symptoms to prevent further cardiovascular strain.
