Math Questions on Blood Pressure Lesson

 Ouestions 1-5 are based on the article, “Younger Men Face Blood Pressure Risk”

 1.      The article states that 25 years after the study had been taken, 197 of the men had died of coronary heart disease, 257 of cardiovascular disease and 759 of all causes. What is the total number of men who had died?

 2.      Of the original 10,874, at the time the article was written, how many participants were still alive?

 3.      According to the article, life expectancy was shortened by 2.2 years for men with high- normal blood pressure and 4.1 years for those with stage 1 hypertension. If the average life expectancy for men in America is 75 years, how long can those with high- normal blood pressure expect to live? How about those with stage 1 hypertension?

 4.      Over the 25 years the study was taken, what is the approximate average of men who had died per year?

 5.      The article tells us that almost 62 percent of those studied had high-normal blood pressure or stage 1 hypertension. Of the 10,874 Chicago men studied, approximately how many men is this?

             Bill Schmidt went to his physician to be treated for high blood pressure. The Physician prescribed medication. After two months, having taken the medication and adjusting his diet, Bill returned to the doctor’s office. His blood pressure was measured at 135/82. This represented a 12% drop in systolic pressure and a 9% drop in diastolic pressure. Rounding to the nearest whole number, what was Bill’s first blood pressure reading?

 Mathematics Key

1.      197+257+759=1,213

2.      10,874-1,213=9,661

3.      75.0-2.2=72.8  years

75.0-4.1=70.9 years

4.      9,661/25=386.44, approximately 386

5.      10,874x0.62=6,741.88, approximately 6,742

            Systolic: 135/0.88=153.4

            Diastolic: 82/0.91-90.1

             The original reading was 153/90
