Factors affecting nutritional well-being

Correct answer: A. Body needs change according to age

Age affects energy needs, growth requirements, nutrient absorption, body composition, activity, and the ability to chew, swallow, or digest food. Children need nutrients for growth, adults need support for health and activity, and older adults may require adjustments for reduced appetite, illness, or absorption. Thus, age is an important factor in nutritional assessment, making option A correct.

Correct answer: C. It can indicate nutrient deficiency or excess

A record of food and fluid intake helps reveal whether the patient is receiving enough energy, protein, vitamins, minerals, and fluids. It can identify poor appetite, skipped meals, restrictive patterns, or excessive intake and should be interpreted with weight, clinical signs, and biochemical information. Intake data alone does not diagnose every form of malnutrition, but it is an important assessment component. Option C is correct.

Correct answer: A. Activity level affects energy expenditure

Physical activity requires muscular work and therefore increases energy expenditure above the amount needed for basic body functions. A mobile patient generally needs more energy than a sedentary or bed-bound patient, although illness, age, body size, and metabolic stress must also be considered. Hence, option A is correct and option D is false.

Correct answer: A. When the disease condition worsens or improves

A change in disease severity, infection, fever, surgery, wound healing, organ function, or recovery can alter energy, protein, fluid, and micronutrient requirements. Therefore, a diet should be reassessed when the patient’s condition changes rather than continued automatically. Changes in a book, plate, or food name do not change physiological needs, so option A is correct.

Correct answer: A. They provide energy but very few essential nutrients

Empty-calorie foods supply energy, often from added sugars or solid fats, but contribute little protein, fibre, vitamins or minerals. Frequent or excessive intake can displace nutritious foods and may promote excess energy intake, unhealthy weight gain and poor diet quality. Such foods can be included occasionally, but a balanced diet should mainly contain nutrient-dense choices from varied food groups.

Correct answer: A. They can change energy and nutrient requirements

Energy and nutrient requirements vary with age, growth stage, sex, health condition, and physical activity. A growing child, an active worker, and an older sedentary person do not require identical diets. Diet planning must therefore be individualised rather than based on one fixed menu. Option A correctly describes this effect.

Correct answer: A. One who has hypertension

Sodium is present in salt and many packaged or processed foods. For some people with hypertension, reducing excessive sodium intake may support blood-pressure management, together with the treatment and lifestyle advice provided by a healthcare professional. Reading labels helps a patient compare products and identify foods with high sodium content. Sodium reduction is not a substitute for prescribed treatment, but option A is correct because label awareness can be especially useful in hypertension.

Correct answer: A. The increased nutritional needs of the mother and developing baby

Pregnancy involves growth of the fetus, expansion of maternal tissues, and preparation for childbirth and breastfeeding. These changes can increase the need for energy, protein, iron, folate, iodine, and other nutrients, although exact requirements vary. A balanced, safe plan is therefore essential, making option A correct.

Correct answer: A. It can decide the need for affordable options

Economic status affects what foods a patient can regularly purchase, prepare, and sustain. A practical nutrition plan should use affordable local foods, seasonal produce, pulses, cereals, and other suitable alternatives rather than recommending costly foods that the patient cannot obtain. When a plan fits the family budget, adherence is more likely. Therefore, option A correctly describes the influence of economic status.

Correct answer: A. Due to disease, activity, age and health recovery

A patient's requirements are not fixed because illness, treatment, age, body weight, physical activity, appetite, absorption and recovery can change. Fever or infection may increase needs, while reduced activity or impaired digestion may alter them. A dietitian therefore reassesses the patient regularly and modifies the plan according to the current condition. Hence, option A is correct.

Correct answer: A. Appetite, chewing, digestion, and disease condition.

Older adults may have reduced appetite, dental problems, swallowing or chewing difficulty, slower digestion, altered taste, chronic disease, and interactions between medicines and nutrients. A suitable plan therefore considers texture, meal size, nutrient density, hydration, and medical restrictions rather than relying on age alone. These individual factors can strongly affect nutritional well-being.

Correct answer: A. To support the nutritional needs of both the mother and the developing foetus.

Pregnancy involves growth of the foetus, development of the placenta, expansion of maternal tissues, and changes in the mother's blood volume and metabolism. Adequate energy, protein, iron, folate, calcium, iodine, and other nutrients support maternal health and fetal development. The diet should be balanced and individualized, not based on avoiding all foods or eating for two without guidance.

Correct answer: A. To support milk production and the mother's nutrient needs.

Lactation requires nutrients and energy for milk production while the mother also needs nourishment for recovery and her own health. A varied diet, adequate fluids, sufficient protein, and appropriate micronutrients help meet these demands. The exact plan depends on the mother's health, appetite, food access, and cultural pattern; it does not mean stopping food or following unnecessary restrictions.

Correct answer: C. It may be a processed food that should be carefully limited

A product high in both sodium and sugar may be highly processed and should be assessed carefully rather than accepted as a routine food. Excess sodium can be problematic for people with hypertension, kidney disease, or heart conditions, while excess sugar can increase blood-glucose and energy intake. The dietitian must also consider serving size and the patient's condition. Hence, option C is correct.

Correct answer: A. To support the needs of the mother and foetus

Pregnancy involves growth of the foetus, development of the placenta, expansion of maternal tissues, and changes in blood volume and metabolism. Adequate energy and nutrients such as iron, folate, iodine, calcium, protein, and other micronutrients support maternal health and foetal development. Requirements should be assessed individually and met through a balanced, safe diet.

Correct answer: A. Meeting the mother's energy, fluid, and nutrient needs

Lactation requires attention to the mother's energy, protein, micronutrient, and fluid needs because she is producing breast milk while maintaining her own body functions. A varied and balanced diet, adequate hydration, and individualized advice support maternal health and milk production. Extreme restriction or removal of protein is unnecessary and may reduce nutritional adequacy.

Correct answer: B. Because vitamin and mineral deficiency can exist at normal weight

Hidden hunger means a deficiency of essential vitamins or minerals that may occur even when total calories and body weight appear normal. A person can consume enough energy from refined or limited foods but still lack iron, iodine, vitamin A, zinc, or other micronutrients. Therefore, weight alone cannot establish nutritional adequacy; diet diversity, clinical signs, and appropriate assessment are also important.

Correct answer: D. Whether the patient actually needs it

A supplement should not be selected merely because it is advertised, attractive, or costly. The patient’s dietary intake, clinical condition, deficiency risk, allergies, drug interactions, and ability to use it should be assessed first. Professional advice is important; therefore, option D is correct.

Correct answer: D. When the patient refuses to eat that food

A nutritionally suitable meal is ineffective if the patient cannot or will not eat it because it conflicts with religious or cultural practice. Respecting food restrictions allows the team to substitute acceptable foods while preserving energy, protein, and therapeutic nutrient targets. Patient-centred planning improves trust, intake, adherence, and clinical outcomes.

Correct answer: A. Level of physical activity

Physical activity is a major determinant of energy expenditure. A person who walks, performs manual work, trains or exercises regularly uses more energy than a sedentary person, so the dietary requirement may be higher. Plate colour, kitchen size and the name of a food do not determine physiological energy need.

Correct answer: A. It decides accessible and affordable food choices

Economic status affects the amount and variety of food a household can regularly purchase, as well as access to refrigeration, cooking fuel, markets, and health services. A nutritious plan should use affordable local foods such as cereals, pulses, seasonal produce, and suitable milk or alternatives. Healthy eating is not limited to expensive foods.

Correct answer: A. Because they make advice easy to understand and adopt

Local examples connect nutrition advice with foods, recipes, customs, prices, and eating habits familiar to learners. This makes messages easier to understand, culturally appropriate, affordable, and practical. People are therefore more likely to accept the advice and apply it in daily life.

Correct answer: A. Available foods become practical options

Food availability strongly influences what people can buy, prepare, and eat regularly. A practical diet plan considers local markets, season, climate, storage, household resources, and cultural preferences. Nutritional goals are more likely to be achieved when suitable foods are accessible and consistently available.

Correct answer: C. To identify growth faltering or malnutrition early

Growth monitoring uses repeated measurements such as weight, length or height, and sometimes mid-upper-arm circumference to compare a child’s progress with growth standards. A concerning pattern can reveal growth faltering, illness, or undernutrition early, allowing timely counselling, referral, treatment, and follow-up.

Correct answer: A. To improve iron absorption

Vitamin C, or ascorbic acid, can enhance the absorption of non-haem iron found mainly in plant foods such as pulses, cereals, and leafy vegetables. Combining these foods with amla, guava, citrus fruits, tomatoes, or another vitamin C source can therefore support iron utilisation. It does not colour food blue, increase salt, or increase fat.
