Question 1

Someone with malabsorption problems who is experiencing flatulence and diarrhea may benefit from avoiding:
A)decaffeinated beverages.
B)lightly seasoned foods.
C)lactose-containing foods.
D)low-fat foods.

Accepted Answer

Lactose-containing foods should be avoided in cases of malabsorption problems, as the body cannot properly digest lactose, leading to symptoms such as flatulence and diarrhea. Lactose-containing foods can be difficult to digest for people with malabsorption problems, leading to flatulence and diarrhea. Avoiding these foods can help manage symptoms.

-MCT oil does not require bile for digestion and absorption.

Accepted Answer

MCT oil is a type of fat that can be easily digested and absorbed by the body without the need for bile. This makes it a good option for people with cholelithiasis, as they may have trouble digesting and absorbing other types of fats due to reduced bile flow. MCT oil (medium-chain triglyceride oil) does not require bile for digestion and absorption, making it a useful source of energy for individuals with cholelithiasis or other conditions affecting bile production or flow.

Question 3

Which of the following is not true of MCT oil?
A)It is inexpensive.
B)It should not be used to fry food.
C)It should be added to the diet gradually.
D)It may have an unpleasant taste.

Accepted Answer

MCT oil is generally more expensive compared to other oils, making option A not true.

Question 4

minerals commonly malabsorbed as a consequence of fat malabsorption are:
A)iron and selenium.
B)zinc and manganese.
C)calcium and magnesium.
D)phosphorous and calcium.

Accepted Answer

Calcium and magnesium are commonly malabsorbed as a consequence of fat malabsorption. Calcium and magnesium are commonly malabsorbed as a consequence of fat malabsorption.

Question 5

malabsorption is associated with all of the following except:
A)weight loss.
B)essential fatty acid deficiency.
C)loss of sodium and potassium.
D)increased risk of kidney stones.

Accepted Answer

The answer of malabsorption is associated with all of the...

Question 6

Malabsorption of certain minerals is common in persons with fat malabsorption.This can ultimately result in:
A)fluid and electrolyte imbalances.
B)increased risk of bone loss.
C)loss of taste acuity.
D)insulin resistance.

Accepted Answer

Fat malabsorption can lead to deficiencies in fat-soluble vitamins like vitamin D, which is crucial for calcium absorption and bone health, increasing the risk of bone loss.

Question 7

Severe liver disease can lead to fat malabsorption because:
A)it reduces the availability of bile.
B)it decreases the production of pancreatic lipase.
C)it results in damage to the intestinal wall.
D)it causes motility disorders.

Accepted Answer

Severe liver disease can reduce the availability of bile, which is necessary for the emulsification and digestion of fats in the small intestine. Without sufficient bile, fat malabsorption can occur. Severe liver disease can lead to a reduced availability of bile, which is necessary for the emulsification and absorption of dietary fats. Without sufficient bile, fat molecules cannot be broken down into smaller particles that can be absorbed by the gut wall, leading to fat malabsorption.

Which of the following are not allowed on a fat-controlled diet?
A)angel food cake, fat-free milk, and pears
B)cherry pie, chocolate milk, and spareribs
C)marshmallows, fat-free yogurt, and green beans
D)oranges, jelly beans, and noodles

Accepted Answer

Spareribs and cherry pie are high in fat and are not allowed on a fat-controlled diet. The other choices listed have low or no fat content and can be included in a fat-controlled diet. Cherry pie and spareribs are high in fat and not allowed on a fat-controlled diet. The other options contain mostly low-fat or fat-free options that would be allowed on such a diet.

Question 10

Malabsorption of fat results in:
A)steatorrhea.
B)loss of amino acids.
C)loss of water-soluble vitamins.
D)weight gain.

Accepted Answer

Malabsorption of fat leads to the inability to properly digest and absorb fats, resulting in the excretion of undigested fat in the stool, known as steatorrhea. This can lead to weight loss rather than weight gain. Loss of amino acids and water-soluble vitamins are not directly related to fat malabsorption. Malabsorption of fat leads to steatorrhea, which is the presence of excessive amounts of fat in the stool due to poor absorption. This condition can also lead to deficiencies of fat-soluble vitamins (such as A, D, E, and K) and calories, resulting in weight loss rather than weight gain. The loss of amino acids and water-soluble vitamins are not directly related to malabsorption of fat.

Question 11

laboratory test can help to diagnosis lactose intolerance?
A)stool fat test
B)Schilling test
C)hydrogen breath test
D)D-xylose test

Accepted Answer

The hydrogen breath test is the most commonly used laboratory test for diagnosing lactose intolerance. The test measures the quantity of hydrogen in the breath after consuming a lactose solution. If lactose is not properly digested, it will be fermented by bacteria in the colon and produce excess hydrogen, which can be detected in the breath. Stool fat tests and D-xylose tests are not specific to lactose intolerance and are used to diagnose other gastrointestinal disorders. The Schilling test is used to diagnose vitamin B12 deficiency. The hydrogen breath test is considered the best choice for diagnosis of lactose intolerance. The test involves drinking a solution of lactose and measuring the amount of hydrogen in the breath. In people with lactose intolerance, bacteria in the colon ferment the lactose, producing hydrogen gas that can be detected in the breath. The test is non-invasive, safe and reliable.

Question 12

Malabsorptive disorders and their treatments can cause all of the following problems except:
A)altered food intake.
B)increased nutrient needs.
C)altered nutrient absorption.
D)weight gain.

Accepted Answer

Malabsorptive disorders and their treatments typically lead to weight loss rather than weight gain. Malabsorptive disorders and their treatments can lead to altered food intake and altered nutrient absorption, which can cause increased nutrient needs. However, weight gain is not a typical problem associated with malabsorptive disorders and their treatments. In fact, malabsorptive disorders often result in weight loss due to malabsorption of nutrients.

Question 13

Case Study 
Cook with Cholelithiasis: Marcia Brown is a 42-year-old Pima Indian who works as a cook in a casino in Arizona.She has just been diagnosed with cholelithiasis.She is 5'4" tall and once weighed 210 pounds.One year ago she underwent gastric bypass surgery and has lost 75 pounds.For several months she had been experiencing episodes of pain in the right upper part of her abdomen.The pain usually began after eating and lasted for several hours.Lately she began to experience nausea and vomiting with the pain and began to run a fever.
-Vitamin B₁₂ is absorbed through the:
A)duodenum.
B)stomach.
C)ileum.
D)colon.

Accepted Answer

Vitamin B12 is absorbed in the ileum, the last part of the small intestine. As Marcia has undergone gastric bypass surgery, it is possible that her absorption of vitamin B12 may be impaired, leading to the need for supplementation. Vitamin B₁₂ is absorbed through the ileum, which is the last part of the small intestine. Cholelithiasis can lead to obstruction of the bile duct, which can interfere with the absorption of fat-soluble vitamins such as vitamin B₁₂. Therefore, it is important for Marcia to ensure an adequate intake of vitamin B₁₂ through either dietary sources or supplementation.

-Celiac disease is characterized by an abnormal immune response to certain amino acids.

Accepted Answer

This statement is not related to the case study about Marcia Brown and is also incorrect. Celiac disease is an autoimmune disorder that affects the small intestine in response to gluten consumption, not amino acids.

Question 15

Schilling test helps to diagnose malabsorption of:
A)fat.
B)vitamin B₁₂.
C)lactose.
D)vitamin B₆.

Accepted Answer

Schilling test is a diagnostic test for vitamin B₁₂ malabsorption. The test is performed by administering a small amount of radioactive B₁₂ orally, followed by an injection of nonradioactive B₁₂. The amount of radioactive B₁₂ and its metabolites excreted in the urine over a period of time is measured. If the body is unable to absorb B₁₂, then the radioactive B₁₂ will not be excreted in urine. The Schilling test is used to diagnose malabsorption of vitamin B₁₂, which is necessary for the production of red blood cells and nervous system function. The test involves giving the patient radioactive vitamin B₁₂ and then measuring the amount that is excreted in the urine. If the majority of the vitamin B₁₂ is excreted, this indicates that it is not being absorbed properly.

-Many lactose-intolerant individuals can tolerate up to 2 cups of milk a day when intake is divided throughout the day and taken with food.

Accepted Answer

Lactose-intolerant individuals can tolerate up to 2 cups of milk a day when intake is divided throughout the day and taken with food.

Question 17

patients with fat malabsorption problems, fat is better tolerated if it is:
A)provided in small portions.
B)monounsaturated.
C)limited to one meal per day.
D)consumed as fried food.

Accepted Answer

Patients with fat malabsorption problems have difficulty digesting and absorbing dietary fats. Therefore, it is recommended that fat is consumed in small portions to help with digestion and absorption. Consuming large amounts of fat at once can worsen symptoms and lead to malabsorption. Monounsaturated fats are also better tolerated than other types of fats, but portion control is still important. Limiting fat to one meal per day may be helpful for some patients, but it is not as effective as consuming small portions throughout the day. Fried foods are generally high in fat and are not recommended for patients with fat malabsorption problems.

Question 18

Lactose intolerance is prevalent among all of the following ethnic groups except:
A)Native Americans.
B)Asians.
C)Latinos.
D)Caucasians.

Accepted Answer

Caucasians are not exempt from lactose intolerance, as lactose intolerance can affect individuals of any ethnicity. Therefore, choice D is the correct answer. Lactose intolerance is prevalent among Native Americans, Asians, and Latinos, but it is not as common among Caucasians. This is due to the fact that people from certain ethnic backgrounds have historically relied less on dairy products in their diets and have not developed the enzymes needed to break down lactose as efficiently.

Question 19

Bacterial overgrowth in the stomach and small intestine can result in:
A)a deficiency of fat-soluble vitamins.
B)weight gain.
C)vitamin B₆ deficiency.
D)abnormal glucose tolerance.

Accepted Answer

Bacterial overgrowth in the stomach and small intestine can interfere with the absorption of fat-soluble vitamins (A, D, E, and K), leading to a deficiency. This is because the bacteria can consume and break down these vitamins before the body has a chance to absorb them. This can result in a variety of health problems, including osteoporosis, anemia, vision problems, and compromised immune function.

Question 20

Kaufman has fat malabsorption and is at risk for developing oxalate stones.Which of the following foods should he avoid?
A)green beans
B)spinach
C)potatoes
D)milk

Accepted Answer

Spinach is high in oxalate and should be avoided to prevent oxalate stone formation. The other options are low oxalate and can be consumed. Spinach is high in oxalates and can increase the risk of oxalate stone formation, so it should be avoided in patients with fat malabsorption. The other options are not particularly high in oxalates and do not need to be avoided.
