Factors affecting nutritional well-being

Correct answer: A. Because appetite, chewing, digestion and disease condition may change

Older adults are not a nutritionally identical group. Age-related changes may reduce appetite, taste, thirst, chewing ability, swallowing comfort, digestion, or nutrient absorption. Chronic diseases, medicines, functional limitations, and personal food preferences may also alter requirements and tolerance. Individualized planning can adjust texture, meal timing, nutrient density, fluids, and restrictions safely. Therefore, age increases the need for assessment rather than justifying one identical diet for everyone.

Correct answer: A. Because an unsuitable consistency can increase choking and aspiration risk

Food consistency is important in dysphagia because the patient may be unable to control thin liquids, thick liquids, or solid pieces safely in the mouth and throat. A medically suitable texture can reduce choking and aspiration, while still helping the patient obtain energy, protein, fluids, and other nutrients. The exact consistency should be selected by qualified health professionals after assessing swallowing ability.

Correct answer: C. In some circumstances, tea may affect iron absorption

Tea contains polyphenolic compounds that can interfere with the absorption of non-haem iron, especially when consumed with or immediately after meals. The effect is relevant to people relying on plant sources of iron or already at risk of deficiency. Diet timing and vitamin C-rich foods may therefore be considered. Option C is correct.

Correct answer: A. Preparing a diet with affordable, local alternatives of similar nutritional value

A therapeutic diet is useful only when the patient can obtain, prepare, and follow it consistently. The expert should discuss the financial barrier and replace costly items with affordable local foods that provide comparable nutrients and suit the medical prescription. This improves feasibility, acceptability, and adherence. Therefore, option A is the correct priority action.

Correct answer: A. One who can eat only small amounts

When a patient can eat only small amounts, each serving should provide concentrated energy and nutrients. Fortified milk, smooth nutrient-rich foods, suitable oils, and protein sources may help, provided they match the medical condition. This strategy improves adequacy without increasing uncomfortable volume.

Correct answer: B. Because weight, sex, activity and disease state also affect it

Age influences energy needs, but it is only one factor. Body weight and composition, sex, physical activity, growth, pregnancy, lactation, fever, infection, trauma and other disease conditions can raise or lower expenditure. Accurate estimation therefore requires a multi-factor assessment rather than an age-only rule.

Correct answer: C. Abdominal fat and metabolic risk may be higher

BMI relates body weight to height but does not show where fat is stored or distinguish fat from muscle. A high waist measurement may indicate excess central or visceral fat, which is associated with greater risk of insulin resistance, type 2 diabetes, hypertension, and cardiovascular disease. Waist measurement should therefore complement, not replace, other assessments.

Correct answer: B. Because income, education, family support, and food availability affect food choices and adherence

A diet plan is effective only when a person can obtain, understand, prepare, and follow it. Income affects affordability, education affects understanding, family support affects implementation, culture affects acceptability, and local availability affects realistic choices. Clinical nutrition must therefore adapt recommendations to social circumstances rather than assuming identical conditions for all patients. Option B is correct.
