Diet therapy

A clearly documented food allergy is an important patient-safety warning. It informs the dietitian, kitchen staff, nurses, and other caregivers which ingredient or food must be avoided and helps prevent cross-contact or accidental service. A reaction can be serious, so the information should be visible, accurate, and communicated during every change of care. Therefore, D is correct.

Diabetes meal planning generally focuses on the amount, type, distribution, and timing of carbohydrate rather than eliminating all carbohydrate foods. Consistent portions, high-fibre choices, appropriate energy intake, and coordination with medicines and physical activity can support blood-glucose control. Individual needs differ, so the plan should be personalised. Complete avoidance of carbohydrates is unnecessary and may reduce diet quality and fibre intake.

Excess sodium can promote water retention and increase vascular pressure in some individuals, contributing to raised blood pressure. Reducing added salt and high-sodium processed foods, while choosing minimally processed foods, can support blood-pressure management as part of an overall healthy dietary pattern. Sodium restriction should be appropriate to the patient’s condition; it does not automatically mean stopping all fluids or eliminating protein.

Lactose intolerance results from inadequate digestion of lactose, the natural sugar in milk, usually because lactase activity is low. Symptoms may include bloating, abdominal discomfort, gas, or diarrhoea after lactose consumption. Management is individual: some people tolerate small portions, yoghurt, or lactose-free products. Unnecessary avoidance of all dairy can reduce calcium and vitamin D intake, so suitable alternatives and professional advice are important.

The primary dietary safety measure in a confirmed food allergy is strict avoidance of the responsible allergen, together with careful label reading and prevention of cross-contact during preparation. The person should receive nutritionally adequate substitutes so that avoidance does not cause deficiencies. Food allergy is an immune reaction and can be serious; suspected reactions require medical evaluation and an emergency plan when indicated. Deliberate exposure should never be attempted without specialist supervision.

Diarrhoea causes increased loss of water and electrolytes, so preventing dehydration is the immediate priority. Suitable oral fluids, oral rehydration solution when indicated, and small amounts of tolerated food can help maintain hydration and energy. Fluids should not be stopped without a specific medical reason. Therefore, option A is correct.

Constipation is often improved by a combination of adequate dietary fibre, sufficient fluid intake, and regular physical activity, provided there is no medical contraindication. Fibre adds bulk and can support bowel movement, while fluids and movement help stool pass more easily. A single food or extreme fasting is not a scientific general solution, so option A is correct.

Food texture modification is important when a patient has difficulty chewing or swallowing, because an unsuitable texture can reduce intake or increase the risk of choking and aspiration. Depending on the assessment, foods may need to be softened, minced, mashed, or thickened. Therefore, option B is correct.

Lack of improvement requires a systematic review rather than blame or immediate discontinuation. The professional should reassess the patient’s condition, diagnosis, intake, adherence, goals, and intervention, and consult the healthcare team when needed. The plan may then be modified on the basis of findings. Hence, option C is correct.

When a patient tolerates food poorly, the diet should be changed gradually and carefully. Portions, texture, frequency, or selected foods may be adjusted according to symptoms and clinical advice. This approach helps identify tolerated foods, reduces discomfort, and supports adequate nutrition. Therefore, gradual modification according to tolerance is the safest and most appropriate principle.

A therapeutic diet is a planned modification of the regular diet to support treatment or manage a health condition. It may alter energy, nutrients, texture, consistency, or meal frequency, but it does not automatically remove every nutrient. Nutritional adequacy and patient tolerance remain important. Thus, the statement that it always removes all nutrients is incorrect.

For a patient with poor appetite, large meals may feel difficult and may further reduce intake. Small, frequent meals can be easier to tolerate, while energy- and protein-rich foods can provide more nutrition in limited quantities. The plan should still be adjusted to the patient's disease, symptoms, swallowing ability, and professional advice. Thus, option A is appropriate.

A patient who is vulnerable to dehydration needs sufficient and appropriate fluids, unless a medical condition requires fluid restriction. Monitoring the amount and frequency of intake helps identify inadequate hydration, while safe water reduces the risk of infection. The diet plan may also include suitable beverages, soups, or oral rehydration preparations according to professional advice. Therefore, option A is correct because fluid balance and water safety directly affect hydration and recovery.

Protein supplies amino acids needed for maintaining body tissues, building new tissue, producing enzymes and hormones, and supporting immune function. During wound healing, illness, surgery, or recovery, both the amount of protein and its quality may matter. A suitable plan considers the patient's needs, ability to digest food, medical condition, and available protein sources; it should not be changed without professional guidance. Therefore, option A is correct because repair and recovery increase the relevance of protein adequacy.

The prescribed or planned diet does not always show what the patient actually consumes. Measuring or estimating real portions helps the dietitian compare intake with requirements and detect inadequate energy, protein, fluids, or other nutrients, as well as excessive intake. It also reveals leftovers, appetite changes, and barriers to eating. This information supports appropriate adjustment and follow-up. Therefore, option A is correct because actual quantity is essential for dietary assessment.

A diet plan should be reviewed when the patient's condition or response changes. Altered appetite, body weight, symptoms, laboratory findings, medication, tolerance, or treatment goals may show that the current plan is no longer suitable. Review allows the dietitian and healthcare team to adjust nutrients, portions, texture, timing, or restrictions safely. Unrelated changes such as shoes, room colour, or paper do not provide a clinical reason. Therefore, option A is correct.

A therapeutic restriction should have a clear clinical purpose supported by the patient's diagnosis, symptoms, treatment, or nutrition assessment. Unnecessary restrictions can reduce variety, enjoyment, nutrient adequacy, and adherence. The dietitian should therefore balance scientific requirements with individual needs and choose the least restrictive effective approach.

Many types of dietary fibre absorb water and increase stool bulk, which can help bowel movement when adequate fluid is available. Gradually increasing fibre together with suitable fluid may soften stool and improve transit. However, fluid advice must consider the patient’s medical condition; people with fluid restrictions, kidney disease or heart failure need individualized professional guidance rather than unlimited intake.

Nausea can be worsened by strong smells, heavy meals, and oily or fried foods. Light, bland, low-odour foods offered in small, frequent portions are generally easier to tolerate. The patient’s individual response should be observed, and fluids should be given as appropriate. Therefore, option A is the most suitable symptom-based diet modification.

Food allergy involves an immune response and may cause serious reactions even after exposure to a small amount of the trigger. Food intolerance generally involves difficulty digesting or processing a food and may require a different approach. Correct identification helps prevent unnecessary restriction and supports safe, individualized diet planning. Hence, option A is correct.

Reducing sodium requires more than avoiding table salt. Processed foods, packaged soups, pickles, sauces, instant mixes, salty snacks, and some breads may contain substantial hidden sodium. Reading labels and selecting fresh, minimally processed foods makes the diet more effective and realistic. Therefore, identifying hidden sodium sources, option B, is the practical priority.

Diabetes management considers the total carbohydrate load, portion size, meal timing, fibre, energy intake, and the person’s medicines and activity. Sugars are important, but starches and other carbohydrate-containing foods also influence blood glucose. A balanced, individualized meal plan is therefore more appropriate than simply removing table sugar. Option C is correct.

Nutritional care is dynamic rather than a one-time instruction. Reassessment is especially important when the disease, laboratory findings, weight, symptoms, appetite, intake, treatment, or tolerance changes. It helps determine whether the existing plan is effective and whether its nutrients, texture, portions, or goals need adjustment. Hence, option A is correct.

When a patient will eat at home, family members may purchase ingredients, prepare meals, control portions, adapt recipes, remind the patient, and provide emotional support. Their involvement can make the prescribed diet practical and improve adherence, provided the patient’s preferences and autonomy are respected. Therefore, option A is the most beneficial situation.

A diet plan is more effective when it fits the patient’s culture, budget, schedule, cooking facilities, food access, symptoms, and preferences. The dietitian should listen without blame, identify the specific barrier, and negotiate realistic substitutions or changes while preserving nutritional goals. This patient-centred approach improves adherence and safety, so option B is correct.
