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 hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?
- A. glucagon
- B. ghrelin
- C. leptin
- D. insulin
Correct answer: C
Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
3. Overweight and obesity often accompany conditions such as _____ that limit mobility or result in short stature, which can lead to feeding difficulties.
- A. Parkinson's disease
- B. muscular dystrophy
- C. Down syndrome
- D. multiple sclerosis
Correct answer: C
Rationale: The correct answer is C, Down syndrome. Down syndrome is often associated with short stature and limited mobility, which can contribute to feeding difficulties and obesity. Parkinson's disease (choice A) primarily affects motor function, but it is not typically associated with short stature. Muscular dystrophy (choice B) primarily impacts muscle strength and does not necessarily lead to short stature. Multiple sclerosis (choice D) is a neurological condition affecting the central nervous system and does not directly cause short stature or feeding difficulties as seen in Down syndrome.
4. When assessing for criteria that signify malnutrition risk, which element would most likely be included as part of the functional assessment data?
- A. severity of illness
- B. presence of pressure sores
- C. localized edema
- D. generalized weakness
Correct answer: D
Rationale: Generalized weakness is a key indicator of malnutrition and is often assessed as part of functional status, reflecting muscle wasting and reduced physical function. The other choices, such as severity of illness, presence of pressure sores, and localized edema, are important factors to consider in a clinical assessment but are not primarily indicative of malnutrition risk. Generalized weakness directly relates to the functional impact of malnutrition on physical performance.
5. What is the end product of lipid digestion?
- A. fatty acid
- B. sucrose
- C. monosaccharide
- D. amino acid
Correct answer: A
Rationale: The correct answer is A, fatty acid. During the process of lipid digestion, triglycerides are broken down into fatty acids and glycerol. These end products are then absorbed into the bloodstream or lymphatic system for further processing. Choices B, C, and D are incorrect because sucrose is a disaccharide, monosaccharide is a simple sugar unit, and amino acid is a building block of proteins, not the end product of lipid digestion.
