Orthostatic levels

An 87-year-old African American male is brought to the clinic by his son for a routine physical exam. His son states, “Dad has been complaining of feeling dizzy, and he is afraid he is going to fall.” When checking the patient’s vital signs, the nurse notes that the blood pressure has reached orthostatic levels and need further evaluation. What assessments need to be made in further evaluating this patient? The son asks what his father’s treatment will be to correct the problem. What is the nurse’s best response? What else can be done if it is not possible to correct the cause of orthostatic hypertension?
