Changes in consistency

Correct answer: A. Soft diet

Explanation: Raw hard vegetables such as raw carrot, radish, or firm cucumber require considerable chewing and may be difficult for a person with poor chewing or swallowing ability. A soft diet includes foods that are tender, soft, mashed, or otherwise easy to chew and swallow. Therefore, raw hard vegetables are least suitable for a soft diet. A high-fibre diet, in contrast, may specifically include vegetables, provided the person can tolerate their texture.

Correct answer: A. To promote safe intake

Explanation: Changing food consistency is a therapeutic measure used for people who have difficulty chewing or swallowing. Food may be thickened, softened, mashed, pureed, or otherwise modified so that it can be controlled more easily in the mouth and swallowed with lower risk of choking or aspiration. The main aim is therefore safe and effective intake, while still providing adequate nutrition and fluids. It is not intended to change the price, hide the food, or unnecessarily increase salt.

Correct answer: A. So nutrition is provided even after form changes

Explanation: Texture modification should not unintentionally reduce energy, protein, vitamins, minerals, or fluid intake. Blending, straining, or thinning may change volume and nutrient density, so meals must be planned to remain nutritionally adequate. The purpose is to preserve nutrition while making the food easier or safer to consume; therefore, A is correct.

Correct answer: A. It may have low nutrient density

Explanation: If a puree is excessively diluted with water or another low-energy liquid, each spoonful may contain fewer calories and nutrients. A patient with a small appetite could then consume insufficient energy and protein even after eating a reasonable volume. Purees should therefore be smooth but nutrient-dense, making option A correct.

Correct answer: A. Doctor or dietitian

Explanation: The appropriate consistency depends on diagnosis, chewing ability, swallowing safety, nutrition status, and treatment goals. A doctor and dietitian, often together with a speech-language or swallowing therapist, assess these factors and recommend the diet. A shopkeeper or neighbour cannot make a clinical decision, so option A is correct.

Correct answer: A. It needs less chewing

Explanation: A full liquid diet provides foods and drinks in liquid or pourable form, so it requires little or no chewing. It may be useful temporarily for some patients with chewing difficulty, although its nutritional adequacy must be planned carefully. It is not necessarily fried, hard, or devoid of nutrients; therefore, A is correct.

Correct answer: A. One with chewing or swallowing problem

Explanation: Crunchy snacks are usually dry, firm, and crumbly, so they require effective chewing and careful swallowing. They may be unsafe or uncomfortable for a patient with chewing weakness or dysphagia. Such a patient may need a softer, moist, or appropriately modified texture after professional assessment. Thus, option A is correct.

Correct answer: A. The number of solid particles is reduced

Explanation: Straining soup separates and removes many solid pieces, fibres, seeds, or other coarse particles by passing the liquid through a sieve or strainer. The resulting soup is smoother and easier to swallow, although its thickness may still depend on the recipe. Straining does not make soup hard, dry, or crunchy. It is therefore a method of modifying consistency and reducing particle size for people who need a smoother liquid preparation.

Correct answer: A. To prevent infection

Explanation: Blending, mashing, straining, and mixing involve extra handling and equipment. If hands, utensils, water, or surfaces are contaminated, microorganisms can enter the food and cause illness. Patients may be especially vulnerable, so handwashing, clean equipment, safe ingredients, and proper storage are essential. Hence, option A is correct.

Correct answer: A. Boiling

Explanation: Boiling cooks food in water or another liquid using moist heat. This heat softens plant cell walls and gelatinises starch, making vegetables, cereals, pulses, and other foods easier to chew. Dehydration removes moisture, while grilling and deep frying may produce a firm or crisp surface. Therefore, option A is correct.

Correct answer: A. Soft diet

Explanation: Thick porridge is soft and semi-solid, and it generally requires less chewing than firm foods. It may therefore be included in a soft diet if the patient can safely manage that thickness. A clear-liquid diet allows transparent fluids, a full-liquid diet is more fluid, and NPO means nothing by mouth. Thus, A is correct.

Correct answer: A. Thick kheer

Explanation: Thick kheer has a smooth, pourable but relatively thick consistency, so it is neither a thin liquid nor a firm solid. This makes it a simple example of a semi-liquid food, provided it is prepared safely and suits the patient’s needs. Papad, raw carrot, and chips are solid foods requiring more chewing. Option A is correct.

Correct answer: A. Soft, moist, and easy to chew

Explanation: A soft diet is designed to reduce chewing effort and make swallowing more comfortable. Foods should generally be tender, moist, soft in texture, and easy to break down in the mouth. Hard, dry, fibrous, or crunchy foods are usually less suitable. Spiciness concerns flavour rather than consistency, so option A is correct.

Correct answer: A. Diet modification

Explanation: Diet modification means deliberately changing one or more features of a usual diet to meet a person’s medical or functional needs. Consistency changes—such as pureeing, mashing, thickening, or making food softer—are one important type of modification. They can support chewing, swallowing, digestion, or recovery. Therefore, option A is correct.

Correct answer: A. Gradually according to patient tolerance

Explanation: After surgery, the digestive system and swallowing ability may not immediately tolerate normal solid food. Diet is commonly progressed step by step—from clear liquids or other prescribed liquids to thicker liquids, soft foods, and eventually a regular diet—only when the patient remains stable and tolerates each stage. Therefore, A is correct.

Correct answer: C. Hard gram

Explanation: A pureed diet should be smooth, uniform, and free from hard pieces or difficult-to-chew particles. Hard gram remains firm and may require substantial chewing, so it does not fit the required consistency unless it is completely cooked and transformed into a smooth puree. The other options are smooth or strained foods. Hence, C is correct.

Correct answer: A. Patient tolerance

Explanation: A prescribed consistency is not automatically safe for every patient. The caregiver should observe whether the patient can manage the food comfortably, including coughing, choking, fatigue, wet voice, discomfort, or refusal. Tolerance and safety should be communicated to the clinical team so the diet can be adjusted. Therefore, A is correct.

Correct answer: A. Liquid such as water or broth

Explanation: Adding an appropriate liquid such as water, milk, stock, or broth can reduce thickness and make a food more fluid. The choice depends on the recipe, nutritional goal, and the patient’s prescribed consistency; simply adding liquid is not always safe for dysphagia. Among these options, a suitable liquid is the correct general method, so A is correct.

Correct answer: A. Add a suitable thickening agent

Explanation: A suitable thickening agent, such as starch-based powder or another prescribed product, can increase the viscosity of a food or drink. The amount must be measured carefully because the required thickness depends on the patient and the clinical prescription. Thickening should not be done merely for appearance. Therefore, option A is correct.

Correct answer: A. To provide safe and adequate food to patient

Explanation: The final purpose of changing consistency is to help the patient consume food safely while still receiving enough energy, protein, fluids, vitamins, and minerals. Texture may be altered to support chewing, swallowing, digestion, or recovery, but it should not unnecessarily reduce nutritional value. Thus, option A combines the two essential goals and is correct.

Correct answer: A. To make chewing and swallowing easier

Explanation: Semi-liquid food has a soft, flowing consistency between a liquid and a solid. It can reduce the effort needed for chewing and swallowing, especially for weak patients or people with oral and swallowing difficulties. The consistency must still be selected according to professional assessment so that the patient receives food safely and adequately.

Correct answer: A. Expert advice should be taken for the correct consistency

Explanation: Coughing while drinking a thin liquid can indicate that swallowing is not adequately protecting the airway. The liquid may be moving too quickly or may be entering the airway. The safe response is to stop experimenting with textures and obtain assessment from a doctor or speech and swallowing specialist, who can recommend an appropriate consistency.

Correct answer: A. Dry food can be difficult to chew and swallow

Explanation: A soft diet should generally be moist, tender, and easy to form into a manageable bolus. Excessively dry food may crumble, require considerable chewing, stick in the mouth, or be difficult to swallow. Moisture and suitable preparation improve comfort and intake, although the exact texture should always follow the patient’s swallowing assessment.

Correct answer: A. Consistency modification

Explanation: Boiling changes the physical texture of a hard food by softening its tissues and making it easier to chew and sometimes easier to swallow. This is therefore a method of consistency modification. It does not primarily change the colour, medicine, or price of the food. The extent of cooking should still be adjusted to the patient’s chewing and swallowing ability and the prescribed diet.

Correct answer: A. Changing food texture

Explanation: Changing diet consistency means changing the physical form or texture of food so that it becomes suitable for a person’s chewing, swallowing, digestion, or medical needs. Food may be made softer, mashed, pureed, strained, thickened, or converted into a liquid. The change is not simply a change in colour, price, or name. The prescribed consistency should be selected according to individual patient requirements.
