1. What describes a common physical change of aging that can affect an older adult's nutrition?

• A. reduced salivary output
• B. increased gastrointestinal motility
• C. abnormal cortisol production
• D. increase in number of taste buds

Correct answer: A

Rationale: Reduced salivary output is a common physical change in aging. This can affect an older adult's nutrition by impacting chewing, swallowing, and taste perception. The decrease in saliva production can make it harder to chew and swallow food effectively, affecting the overall eating experience. Additionally, saliva plays a role in taste perception, so a reduction in salivary output can lead to alterations in how food tastes, potentially impacting an individual's appetite and food choices. Increased gastrointestinal motility (choice B) is not typically associated with aging and would not directly affect nutrition. Abnormal cortisol production (choice C) is related to hormonal changes and is not a common physical change of aging that affects nutrition. An increase in the number of taste buds (choice D) is not a typical change associated with aging and would not have a significant impact on an older adult's nutrition.

2. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

3. Which nutrient deficiency are people who regularly take prescription drugs such as steroids and diuretics at risk for?

• A. Potassium
• B. Selenium
• C. Iodine
• D. Chloride

Correct answer: A

Rationale: Regular intake of prescription drugs like steroids and diuretics can lead to the loss of potassium in the body, causing a condition known as hypokalemia. Therefore, people on these medications require careful monitoring and often need potassium supplementation to prevent this deficiency. The other options, selenium, iodine, and chloride, are incorrect because there is no specific link between their deficiency and the regular use of steroids and diuretics.

4. For patients with hypertension, which dietary change is most recommended?

• A. Increase salt intake
• B. Reduce fiber intake
• C. Increase potassium intake
• D. Reduce sugar intake

Correct answer: C

Rationale: Increasing potassium intake can help reduce blood pressure in hypertensive patients.

5. Which food item should be recommended to prevent choking in toddlers?

• A. Banana slices
• B. Popcorn
• C. Hot dogs
• D. Carrot sticks

Correct answer: A

Rationale: Banana slices are less likely to cause choking compared to other options.
