Feeding routes

Correct answer: B. From the nose to the stomach

Explanation: A nasogastric tube is an enteral feeding tube inserted through the nose and guided down the pharynx and oesophagus until its tip reaches the stomach. The word “naso” refers to the nose, while “gastric” refers to the stomach. Hence, option B is correct. The tube is not passed from the mouth, skin, or eye in the usual nasogastric route.

Correct answer: C. Directly into the stomach

Explanation: In gastrostomy feeding, a tube is placed through an opening made in the abdominal wall and its internal end lies in the stomach. It allows nutrition, fluids, or medicines to be given directly when normal swallowing is difficult or unsafe. It is not inserted into an arm vein, mouth, or ear, so option C is correct.

Correct answer: D. Vein route

Explanation: Parenteral nutrition is delivered directly into the bloodstream through intravenous access, bypassing the mouth and gastrointestinal tract. It may be considered when the digestive tract cannot be used adequately. Because the nutrients enter through a vein rather than the gut, option D is correct.

Correct answer: A. Enteral route

Explanation: If the gastrointestinal tract is functioning, enteral nutrition is generally preferred because it uses the body’s natural digestive pathway and helps maintain gut function. It can be given orally or through a feeding tube. Parenteral nutrition is reserved for situations in which the gut cannot be used adequately; therefore, A is correct.

Correct answer: B. It is natural and simple

Explanation: Oral feeding is the most natural and simple method when a patient can chew and swallow safely. It uses the normal mouth-to-gut process, is usually less invasive, and may support normal eating and enjoyment of food. It is not suitable when swallowing is unsafe, but under the stated condition option B is correct.

Correct answer: C. Thin and strained

Explanation: Tube-feeding material should generally be smooth, sufficiently thin, and free from lumps or fibres that could block the tube. It must also be prepared hygienically and used according to professional instructions. Hard, dry, raw, or chunky food is unsuitable for most feeding tubes. Therefore, option C is correct.

Correct answer: D. The patient’s condition and ability to take food

Explanation: Selection of a feeding route begins with assessment of the patient’s medical condition, level of consciousness, swallowing ability, digestive function, and nutritional requirements. These factors determine whether oral, enteral, or parenteral support is safe and appropriate. Food colour and plate price are irrelevant, so option D is correct.

Correct answer: A. Tube feeding

Explanation: An unconscious patient may lack protective swallowing reflexes, so oral feeding can cause choking or aspiration. After proper clinical assessment, tube feeding may be considered to provide nutrition through the digestive tract when appropriate. The exact route and timing require trained professional supervision; therefore, option A is correct.

Correct answer: B. When nutrition through the gut cannot be provided adequately

Explanation: Parenteral nutrition may be considered when the gastrointestinal tract cannot be used effectively or cannot provide adequate nutrition, such as in selected serious illnesses. Nutrients are delivered intravenously under medical supervision. It is not chosen merely because of food preference or presentation. Thus, option B is correct.

Correct answer: C. Feeding through a nasogastric tube

Explanation: Feeding through a nasogastric tube is enteral because the formula enters the stomach and continues through the digestive tract. Enteral feeding can use the mouth or a tube, as long as nutrients reach the gastrointestinal system. Skin ointment, massage, and changing clothes are unrelated; therefore, option C is correct.

Correct answer: D. Parenteral nutrition

Explanation: Nutrition delivered through a vein is called parenteral nutrition. It enters the bloodstream directly and therefore bypasses the mouth and gastrointestinal tract. It is used only for appropriate clinical indications and requires careful monitoring of fluids, nutrients, and complications. Hence, option D is correct.

Correct answer: A. The ability to chew and swallow safely

Explanation: Safe oral feeding requires the patient to control food in the mouth, chew appropriately, and swallow without a high risk of choking or aspiration. The person’s consciousness and swallowing function should be assessed before feeding. Running, colour recognition, and writing do not determine oral-feeding safety, so A is correct.

Correct answer: B. To prevent infection

Explanation: Hygiene in tube feeding reduces the chance that harmful microorganisms will enter the formula, equipment, or patient. Clean hands, safe preparation, clean containers, and proper handling help prevent gastrointestinal and other infections. Hygiene does not aim to improve colour or decoration; therefore, option B is correct.

Correct answer: C. A patient eating khichdi by mouth

Explanation: The oral route means that food or fluids are taken directly through the mouth and swallowed. A patient eating khichdi by mouth is therefore a clear example. Nutrition through a vein is parenteral, while nasogastric and gastrostomy tubes provide enteral tube feeding. Hence, option C is correct.

Correct answer: D. One who cannot receive enough food by mouth for a long time

Explanation: A gastrostomy may be considered when a patient is expected to need enteral nutrition for a longer period and cannot obtain enough nutrition safely by mouth. The tube enters the stomach through the abdominal wall. It is a clinical decision based on assessment, not a response to temporary hunger or food preference; therefore, D is correct.

Correct answer: B. Parenteral route

Explanation: The parenteral route delivers nutrients directly into the bloodstream, usually through intravenous access, so the mouth and digestive tract are bypassed. It is different from oral and enteral feeding, in which nutrients pass through the gastrointestinal system. Because the question describes direct blood delivery, option B is correct.

Correct answer: D. The healthcare team after assessing the patient's condition

Explanation: The feeding route is selected by the healthcare team after considering the patient’s medical condition, level of consciousness, ability to chew and swallow, functioning of the digestive tract, nutritional needs, and safety risks. Oral, enteral, or parenteral feeding must never be chosen merely by personal preference, because an unsuitable route may cause aspiration, inadequate nourishment, or other complications. Therefore, option D is correct.

Correct answer: A. Small, frequent meals by the oral route

Explanation: When a patient can swallow safely and the digestive tract is functioning, improving oral intake is generally the simplest initial approach. Small, frequent, energy-dense meals can be easier to tolerate than large meals and may improve total intake. The exact plan must still be guided by a healthcare professional. Intravenous nutrition is not automatically required merely because intake is low, so option A is correct.

Correct answer: B. It can reduce reflux and aspiration risk

Explanation: Keeping the patient’s head and upper body elevated during tube feeding helps food move in the intended direction and may reduce regurgitation, reflux, and aspiration of feed into the airway. The patient should be positioned and monitored according to clinical instructions, both during feeding and for the recommended period afterward. Thus, option B is correct.

Correct answer: C. Smooth, strained, and of the prescribed thin consistency

Explanation: Tube feed should be smooth, free from lumps and large particles, and prepared at the consistency prescribed for that particular tube and patient. Straining can remove pieces that might obstruct a narrow tube. Feed should also be administered according to professional instructions, with appropriate flushing when advised. Therefore, smooth strained feed of the correct consistency is the best answer, option C.

Correct answer: A. Colour of the plate

Explanation: A feeding route describes the bodily pathway through which nutrients enter the patient. The oral route uses the mouth and gastrointestinal tract, the enteral route delivers feed into the gastrointestinal tract usually through a tube, and the parenteral route delivers nutrients into the bloodstream while bypassing the gut. Plate colour may affect presentation, but it is not a nutritional pathway. Therefore, option A is correct.

Correct answer: C. Soft khichdi eaten by mouth

Explanation: Oral feeding means that the patient receives food or fluid through the mouth and swallows it. Soft khichdi eaten by mouth is therefore an oral example. Intravenous nutrient fluid uses the parenteral route, while liquid delivered through a nasogastric tube is enteral tube feeding. The route is identified by how the nutrition enters the body, so option C is correct.

Correct answer: D. Parenteral nutrition

Explanation: If the intestine cannot adequately digest or absorb nutrients, nutrition through the gastrointestinal tract may not be suitable. In such circumstances, parenteral nutrition may be considered because nutrients can be delivered directly into the bloodstream, bypassing the gut. The decision depends on the diagnosis, duration, and clinical assessment, and must be made by the healthcare team. Therefore, option D is correct.

Correct answer: A. Unsafe or inappropriate feeding

Explanation: Choosing the correct feeding route helps match nutrition delivery with the patient’s swallowing ability, digestive function, consciousness, and medical needs. It can reduce hazards such as aspiration, choking, tube-related problems, inadequate intake, and inappropriate use of intravenous nutrition. It does not protect a person from nutrition or hygiene; instead, it supports safe nutritional care. Thus, option A is correct.

Correct answer: B. Oral route

Explanation: In oral feeding, food or liquid enters through the mouth, and a patient who has adequate ability can chew and swallow it independently. Tube feeding delivers nutrition through a tube without requiring normal chewing, while intravenous feeding sends nutrients into the bloodstream and does not involve the mouth or swallowing. Therefore, when independent chewing and swallowing are described, the oral route, option B, is correct.
