The definition of impaired glucose tolerance is:
Blood glucose levels between 140 and 199 mg/dl two hours after a meal are considered impaired glucose tolerance. A plasma glucose level of 100–125 mg/dl during fasting is another indicator of impaired glucose tolerance. Diabetes can be diagnosed with a casual plasma glucose level of 200 mg/dl or higher.
Which of the following goals does the National Health and Nutrition Examination Survey (NHANES) aim to achieve?
Americans from the age of two months to sixty-five and older participate in the National Health and Nutrition Examination Survey (NHANES), which uses 24-hour recalls to gather dietary data. Treatment for increased cholesterol levels and the identification of low birth weight infants are not NHANES objectives.
By using the Guthrie test, one can diagnose:
A blood test called the Guthrie test is used to identify phenylketonuria in newborns. It identifies the growth of bacteria in an agar culture caused by an excess of phenylalanine.
An autosomal recessive condition in babies known as maple-syrup urine disease (MSUD) is brought on by:
Leucine, isoleucine, and valine are branched-chain amino acids that the body is unable to metabolize, which results in the autosomal recessive illness known as maple-syrup urine disease (MSUD) in babies. A mutation in the gene regulating alpha-keto acid dehyrogenase activity is the cause of the incapacity to degrade branched-chain amino acids. Vomiting, tiredness, and neurologic abnormalities are among the symptoms of multiple sclerosis with diarrhea (MSUD) that are linked to plasma leucine levels above 10 mg/dl.
The following are indications of liver cirrhosis:
Ascites, or abdominal edema, and hypoalbuminemia are clinical indicators of cirrhosis of the liver, which is caused by the replacement of healthy liver cells by fibrous connective tissue. The occlusion of normal blood flow caused by this abnormal tissue accumulation eventually results in portal hypertension, esophageal vein enlargement, hypernatremia, and an increase in the amount of plasma in the liver. Reduced serum albumin and fat malabsorption ultimately lead to nutritional deficits as a result of these alterations.
Which of the following gastrointestinal procedures has the greatest negative impact on one's ability to eat?
The most harmful effect on nutritional status is caused by ileal resection, which is the removal of all or part of the ileum. This is because it interferes with the activity of bile salts, which is necessary for the breakdown of fat, and reduces the absorption of many nutrients, including fat-soluble vitamins. The ileum can partially replace the jejunum's absorptive capacity during jejunal resection surgery. A portion of the stomach is removed during the Billroth I and Billroth II procedures in an effort to aid in weight loss. The small intestine can make up for lost function and manage absorption and digestion in both of these procedures.
DASH diets are frequently used to treat:
The DASH diet, also known as the Dietary Approaches to Stop Hypertension, was created to treat hypertension by encouraging the consumption of fruits and vegetables high in potassium and magnesium, two minerals that lower blood pressure.
A successful program for nutrition screening:
The foundation of a successful nutrition screening program is the understanding of sensitivity and specificity. Specificity aids in excluding people who are not at nutritional risk, while sensitivity ensures that people at nutritional risk are identified through a nutrition screening program. Nutrition screening programs are utilized in populations of all ages, not only children, and may employ a variety of instruments to gather nutritional data.
Dumping syndrome has a connection to:
The flow of water into the jejunum brought on by the presence of carbohydrates is linked to dumping syndrome. It causes diarrhea and is frequently associated with stomach resection surgery. When carbohydrates are quickly absorbed and digested in the gut, an excess of insulin is secreted, which can cause reactive hypoglycemia.
Among the objectives of cystic fibrosis treatment are:
Increased calories, protein, and fat intake as well as pancreatic enzyme replacement are the main objectives of treatment for cystic fibrosis. The wasting illness known as cystic fibrosis is marked by an increased requirement for all nutrients, including sodium, which is expelled through perspiration. Treatment usually includes pancreatic enzyme supplementation since mucus might clog the pancreatic duct.
Of the following, only one is untrue regarding a low serum albumin level?
No, esophageal reflux does not result in a low serum albumin level. Low blood albumin levels are frequently observed in nephritic syndrome, which causes significant protein loss in the urine, as well as in ascites in liver illness. They may also be a sign of the protein-calorie malnutrition of kwashiorkor.
