A person with lactose intolerance should be most careful to limit their intake of:

Correct Answer: A

Rationale: Individuals with lactose intolerance lack the enzyme lactase needed to break down lactose, the sugar in dairy products. Milk contains a high amount of lactose, making it crucial for those with lactose intolerance to limit their intake. Yogurt and cheese, on the other hand, have lower lactose content due to the fermentation process which reduces lactose levels, making them better tolerated by many with lactose intolerance. Corn syrup, although high in sugar, does not contain lactose and is unrelated to lactose intolerance. Therefore, the correct answer is 'milk' as it is a significant source of lactose, which can trigger symptoms in individuals with lactose intolerance.

Correct Answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.

Correct Answer: A

Rationale: The most likely nutrition-related side effect after head and neck surgery for cancer treatment is aspiration. This is due to changes in swallowing mechanics, which can cause food or liquids to be inhaled into the lungs. While acid reflux, dumping syndrome, and diarrhea are potential side effects related to nutrition, they are not as directly connected to head and neck surgery. Acid reflux is more often related to issues with the lower esophageal sphincter, dumping syndrome is typically a complication of gastric surgery, and diarrhea can have various causes, including certain medications or gastrointestinal illnesses.

Correct Answer: A

Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.

Correct Answer: D

Rationale: Lipids are carried in the bloodstream in the form of lipoproteins. Lipoproteins are complexes of proteins and lipids that transport fats to various parts of the body. While micelles, glycolipids, and lecithin are all related to lipid metabolism, they are not the primary carriers of lipids in the bloodstream. Micelles are small lipid clusters in the intestines, glycolipids are lipids with a carbohydrate attached, and lecithin is a type of phospholipid. Therefore, lipoproteins are the correct answer as they are specifically designed for transporting lipids through the bloodstream.

Correct Answer: C

Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.

Correct Answer: D

Rationale: Thrombolytic drugs are typically administered immediately after a heart attack to dissolve the clot blocking the coronary artery and restore blood flow to the heart muscle. Antilipemic drugs are used to lower lipid levels and prevent atherosclerosis, but they are not typically administered immediately after a heart attack. Corticosteroids are used to reduce inflammation and suppress the immune response, which are not immediate concerns after a heart attack. Diuretics are used to reduce fluid build-up and lower blood pressure, but these are not the primary concerns immediately following a heart attack.

Correct Answer: D

Rationale: An occupational therapist is the team member who works with the client to evaluate the need for special feeding devices and teaches the client how to use them. Occupational therapists specialize in helping individuals with physical or cognitive impairments to perform daily activities. In this scenario, the need for special feeding devices may be due to impaired motor function or disability, making the occupational therapist the correct choice. The other options, dietitian, speech-language pathologist, and dietetic technician, do not typically specialize in evaluating the need for feeding devices or teaching clients how to use them.

Correct Answer: C

Rationale: The correct answer is C, intramural nerve plexus. The intramural nerve plexus is the interrelated network of nerves within the gastrointestinal wall that regulates its muscular action. The gastric nerve plexus (choice A) specifically pertains to the network of nerves in the stomach, not the entire gastrointestinal wall. The biliary nerve plexus (choice B) is associated with nerve supply in the liver, gallbladder, and bile ducts, not the gastrointestinal wall. The intestinal nerve plexus (choice D) is a general term that may refer to various nerve networks within the intestines but does not specifically address the entire gastrointestinal wall.
