Significance

Correct answer: A. A patient after mouth surgery

Explanation: After mouth surgery, chewing and swallowing may be painful or difficult, so soft foods can reduce mechanical irritation and make eating safer and easier. Increased protein supplies amino acids for wound healing, immune function and tissue repair. The diet should be individualized for texture, temperature, energy, allergies and medical restrictions, with progression toward normal consistency as healing permits.

Correct answer: A. Vitamin C can improve iron absorption

Explanation: Vitamin C increases the absorption of non-haem iron from plant foods by reducing ferric iron to the more absorbable ferrous form and by helping keep iron soluble in the intestine. Citrus fruit, guava, amla, tomatoes, and other vitamin-C foods may therefore accompany iron-rich meals. Tea and coffee near meals can reduce iron absorption and may be separated.

Correct answer: A. To improve health, function and quality of life through nutrition support in disease care

Explanation: The broad purpose of clinical nutrition is to provide individualized nutrition support during illness. It helps maintain or restore nutritional status, support healing and immunity, preserve physical function, improve tolerance of treatment, and enhance quality of life. It complements medical care rather than replacing medicines or other treatment.

Correct answer: A. Protein may be used for energy

Explanation: When carbohydrate and fat do not provide enough energy, the body can break down amino acids and use protein as fuel. This is called loss of the protein-sparing effect. Protein used for energy is then less available for collagen formation, immune function, enzyme production, and rebuilding damaged tissue, which can delay wound healing.

Correct answer: B. Whole fruit provides fibre and may slow sugar effect

Explanation: Whole fruit retains its fibre and usually takes longer to eat, which may slow carbohydrate absorption and improve fullness compared with rapidly consumed juice. Juice can contain a concentrated amount of sugars with less fibre. Portion size, total carbohydrate, and the patient’s glucose response must still be considered.

Correct answer: A. It does not fully show body composition

Explanation: BMI is calculated from weight and height and is useful for screening population-level weight status. However, it cannot distinguish muscle from fat or show where fat is distributed. A muscular person may have a high BMI without excess fat, while another person may have normal BMI but high abdominal fat. Other assessments are therefore needed.

Correct answer: A. Because information alone is not always enough

Explanation: Knowing a healthy practice does not automatically make a person follow it. Behaviour change links knowledge with regular action, such as reducing sugary drinks or adding vegetables. Small achievable goals, supportive counselling, monitoring, and follow-up help make healthier eating habits lasting.

Correct answer: A. It can affect fluid balance and raise blood pressure

Explanation: Sodium helps regulate extracellular fluid, but excessive intake can cause the body to retain more water in susceptible people. The resulting increase in blood volume may raise blood pressure. Salt, packaged foods, instant foods and processed snacks can contribute substantial sodium, so label reading and moderation are important.

Correct answer: C. Because they can be fresh, affordable, and nutritious

Explanation: Seasonal produce is harvested during its natural growing period and is commonly available in larger quantities. This may improve freshness and affordability, while fruits and vegetables can provide vitamins, minerals, fibre, and protective phytochemicals. Seasonality is helpful, though food must still be clean and safe. Thus option C is correct.

Correct answer: B. Wash first then cut as needed

Explanation: Vegetables should generally be washed under clean running water before cutting. Cutting first and soaking for a long time can increase the loss of water-soluble vitamins and may spread contamination through the cut surfaces. Washing also removes soil and some microbes. Thus washing first and cutting as needed, option B, is correct.

Correct answer: A. Nourishing full liquid option

Explanation: A nutritionally complete liquid or full-liquid option can supply energy, protein, and other nutrients in a form the patient is more willing and able to consume. Plain sweet water provides mainly fluid and sugar, while dry or salty foods may be difficult or inappropriate. The liquid plan must still meet medical and swallowing requirements.

Correct answer: A. One who has difficulty chewing or swallowing

Explanation: A pureed diet changes food into a smooth, uniform consistency that may be easier to manage for a patient with chewing difficulty or selected swallowing problems. It must be prescribed carefully because some swallowing disorders require a specific thickness, and foods should remain nutritionally adequate rather than being diluted without purpose.

Correct answer: A. Improving swallowing safety and tolerance

Explanation: Food thickness may be adjusted for a patient with dysphagia or reduced swallowing control. An appropriate consistency can slow the flow of food, improve oral control, and reduce the risk of coughing or aspiration. The exact thickness must be assessed and prescribed by a qualified professional because an unsuitable texture can be unsafe. Nutrient reduction is not the purpose.

Correct answer: A. Texture modification

Explanation: Mashing changes the physical texture and consistency of food without necessarily changing its basic ingredients. It can make food softer and easier to chew, but it is not automatically safe for every swallowing disorder. The required texture should be selected according to assessment and clinical guidance.

Correct answer: B. Simple, local, and practical

Explanation: Community nutrition education works best when people can understand and apply the message in daily life. Local language, familiar foods, culturally suitable examples, and practical actions improve participation and recall. Technical complexity or frightening statements can confuse people and reduce trust and willingness to change behaviour.

Correct answer: A. A balanced low-salt diet

Explanation: For many people with hypertension, reducing excess sodium and choosing a balanced pattern rich in vegetables, fruits, pulses, whole grains, and suitable protein can support blood-pressure control. Processed foods, salty snacks, pickles, and papad may contribute substantial sodium. Diet advice must still be individualised and coordinated with medical care.

Correct answer: A. Through diet guidance related to inactivity, fast food, and stress

Explanation: Urban lifestyles may involve prolonged sitting, frequent fast-food consumption, irregular meals, poor sleep, and stress. These factors can contribute to obesity, diabetes, hypertension, and cardiovascular risk. Clinical nutrition addresses them through realistic meal planning, healthier substitutions, portion guidance, behaviour counselling, and monitoring alongside medical care.
