2. Cherri Pitts brings in her morning blood sugar numbers over the last week for you to look at. They were 102 mg/dl, 134 mg/dl, 106 mg/dl, 144 mg/dl, 199mg/dl, 98 mg/dl and 109mg/dl. What is her average weekly blood sugar? Her goal was to be under 120 mg/dl. She was told her glucometer could have an error of +/- 10%. If she accounts for this possible error, would it put her under her goal?

Yes accounting for the possible ± 10% glucometer error would put her under her goal

Explanation:

The blood sugars numbers are;

102 mg/dl

134 mg/dl

106 mg/dl

144 mg/dl

199 mg/dl

98 mg/dl

109 mg/dl

The number of data values, n = 7,

The sum (∑x) of the average blood sugar numbers = 102 + 134+ 106 + 144 + 199 + 98 + 109 = 892 mg/dl

The average = (The sum of the average blood sugar numbers)/(The number of data values)

Her average weekly blood sugar level = (∑x)/n = 892/7 = 127.43 mg/dl

Her average weekly blood sugar level = 127.43 mg/dl >  120 mg/dl

Accounting for the ± 10% error, we have;

The range of her average weekly blood sugar level is 127.43 × (1 - 0.1) to  127.43 × (1 + 0.1)

Her average weekly blood sugar level range is from 114.69 m/dl to 140.17 m/dl

Therefore, since 114.69 m/dl < 120 m/dl, it puts her under her goal.

shhh" is a calming noise that is soothing to the brain . but if ur bf still has nightmares and need mommy and daddy u should get a new bf . u deserve better .

sorry for isaiah but he sounds like a wimp

    however, coronary heart disease , or chd, is actually a result of coronary artery disease, or cad, said edward a. fisher, m.d., ph.d., m.p.h., an american heart association volunteer who is the leon h. charney professor of cardiovascular medicine and also of the marc and ruti bell vascular biology and disease program at the nyu school of medicine.

  with coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. view an illustration of coronary arteries. this is also called ischemia. it may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot.

    the traditional risk factors for coronary artery disease are high ldl cholesterol, low hdl cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to fisher. obesity may also be a risk factor.

    “coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said fisher, who is former editor of the american heart association journal, atvb. “preventive measures instituted early are thought to have greater lifetime benefits. healthy lifestyles will delay the progression of cad, and there is hope that cad can be regressed before it causes chd.”

  living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activity can play a big role in avoiding cad.

    “coronary artery disease is preventable,” agreed johnny lee, m.d., president of new york heart associates, and an american heart association volunteer. “typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.” if you feel any of these symptoms, don’t delay — call 9-1-1.
