A 20-year-old woman has visited her family physician due to occasional bouts of bloody diarrhea over the past several weeks, a phenomenon that she experienced 2 years prior as well.

A 43-year-old male who is 5′10″ tall and weighs 216 lb has been informed by his nurse practitioner that his body mass index (BMI) is 31. Which of the following clinical conclusions based on these data would his nurse be most justified in rejecting? A) Further investigation of his nutritional status is needed to supplement the BMI value. B) The client faces an increased risk of type 2 diabetes and hyperlipidemia. C) He is classified as being obese, likely as the result of the interplay of genetic and lifestyle factors.

A 48-year-old woman has been diagnosed with extrahepatic cholestasis following a thorough history, ultrasound, and blood work. Which of the following symptoms most likely caused her to seek medical treatment, and what consequence to her health problem would the medical team anticipate? A) Complaints of lower flank pain with consequences of impaired fat metabolism B) Anorexia with consequences of impaired drug metabolism and blood filtration C) Skin xanthomas (focal accumulations of cholesterol) with consequences of increased risk of bleeding due to deficient clotting factors D) Pruritus with consequences of deficient levels of fat-soluble vitamins

A 51-year-old male professional is in the habit of consuming six to eight rum and cokes each evening after work. He assures the nurse practitioner who is performing his regular physical exam that his drinking is under control and does not have negative implications for his work or family life. How could the nurse best respond to the client's statement? A) "You are more than likely inflicting damage on your liver, but this damage would cease as soon as you quit drinking." B) "That may be the case, but you are still creating a high risk of hepatitis A or B or liver cancer." C) "In spite of that, the amount of alcohol you are drinking is likely to result first in cirrhosis and, if you continue, in hepatitis or fatty liver changes." D) "When your body has to regularly break down that much alcohol, your blood and the functional cells in your liver accumulate a lot of potentially damaging toxic byproducts."

A 77-year-old woman has been admitted to hospital following several weeks of increasing fatigue. On observation, she is pale, and blood work indicates she has low hemoglobin and red cell counts. Stool tests for occult blood are positive, and following endoscopy, she has been diagnosed with an upper GI bleed that has been shown to originate in her stomach. She admits to regularly exceeding the recommended doses of nonsteroidal anti-inflammatory drugs (NSAIDs) in an effort to control her rheumatoid arthritis. Which of the following phenomena is most likely responsible for her present health problems? A) NSAIDs increase the gastric production of gastrin, increasing gastric secretions and lowering stomach pH. B) Drugs such as NSAIDs increase the H+ levels and thus decrease gastric pH, resulting in insult to the stomach lining. C) NSAIDs, aspirin, and other drugs increase prostaglandin synthesis, resulting in disruption of cellular structures lining the stomach. D) NSAIDs can disrupt the permeability of the gastric mucosa, causing hydrogen ions to accumulate in the mucosal cells of the lining.

A 79-year-old male resident of a long-term care facility has contracted Clostridium difficile and is experiencing consequent diarrhea. Auscultation of the man's abdomen indicates hyperactive bowel sounds. What process in the man's small intestine is most likely accompanying his current status? A) Pathogenic microorganisms are causing dilation of his small intestine, increasing motility. B) Segmentation waves have become more frequent as a result of his infection. C) Intestinal stasis brought on by infection is preventing his small intestine from sufficiently slowing the rate of motility. D) Inflammation is accompanied by an increase in peristaltic movements of his small intestine.

D
