Q 6) Consider that the radiusof the blood vessel hasdecreased to (80%) of itsoriginal value due to partialblockage (the plaque), and thebody compensates for this byincreasing the pressuredifference along the vessel tokeep the flow rate constant,by what factor must thepressure difference increase?

We know that blood moves from high pressure to low pressure. Heart pumps blood into the arteries…

Answered: Q 6) Consider that the radius of the…

Hypertension was diagnosed in G.S., who is 30 years old. Both her mother and sister have hypertension,and both were also in their thirties when it was diagnosed. G.’s most current blood pressure reading is150/96 mm Hg, and for this reason the nurse practitioner has recommended therapy with captopril(Capoten), light exercise in the form of walking, and relaxation therapy. After 1 month of therapy, G.’sblood pressure is 145/86 mm Hg. Stress reduction has been the biggest obstacle in her treatment,because she is a lawyer with a prominent law firm and has found that her blood pressure is consistentlyelevated (160/100 mm Hg) whenever she measures it at work. At this follow-up visit, she is also given aprescription for a diuretic to help with her blood pressure control.4. What lifestyle changes would you, as her nurse, recommend that she make, and, even moreimportant, what information would you give her to help her change her lifestyle and moreeffectively reduce the stress in her life?
