Feeding routes

Correct answer: A. Not giving food or drinks by mouth to the patient

Explanation: No oral feeding means that food, fluids, or medicines are not given by mouth for a specified medical reason and period. It may be ordered before surgery, during certain gastrointestinal conditions, or when swallowing is unsafe. It does not mean that nutrition is unnecessary; alternative support may be prescribed by the clinical team.

Correct answer: B. Thin and strained

Explanation: Tube-feeding preparation should have a suitable smooth or liquid consistency so that it can pass through the tube without blockage. Straining removes lumps and coarse particles, while correct hygiene, preparation, storage, and prescribed volume reduce the risk of contamination and complications. The exact formula and thickness depend on the tube, patient, and medical prescription; hard, raw, fibrous, or lumpy food is unsuitable.

Correct answer: A. Patient may develop intolerance or vomiting

Explanation: Tube feeding must be administered at the prescribed rate because the digestive system may not tolerate a rapid volume of feed. Feeding too quickly can cause nausea, abdominal discomfort, cramps, regurgitation, vomiting, diarrhoea, or aspiration. Therefore, the rate is adjusted and the patient is monitored for tolerance by trained healthcare personnel.

Correct answer: A. It is the natural and more normal route

Explanation: When a patient can swallow safely and consume enough food, oral feeding uses the normal mouth-to-stomach route and usually supports comfort, taste, enjoyment, social participation, and normal digestive activity. Tube feeding is reserved for situations in which oral intake is unsafe or inadequate. The decision must consider swallowing ability, aspiration risk, nutritional needs, and clinical advice.

Correct answer: B. Infection and intolerance

Explanation: Tube-feeding formulas and equipment can become contaminated when hands, containers, water, or feeding tubes are not handled hygienically. Microbial contamination may cause infection, diarrhoea, vomiting, abdominal discomfort, or feeding intolerance. Safe practice includes hand hygiene, clean preparation, appropriate storage, correct administration, and cleaning of equipment according to professional instructions. Food colour and plate weight are not meaningful safety indicators.

Correct answer: A. It is the natural and normal route

Explanation: When a patient is conscious, able to swallow safely, and can meet needs by mouth, oral feeding is the natural route and usually supports normal eating, taste, and social participation. Tube feeding is considered when oral intake is unsafe or inadequate; it is not automatically forbidden or nutritionally inferior.

Correct answer: A. Patient cannot swallow safely

Explanation: Severe unconsciousness can reduce protective swallowing and coughing reflexes, so the patient may be unable to coordinate chewing, swallowing, and airway protection. Food or liquid may enter the airway and cause choking or aspiration pneumonia. Therefore, oral feeding should not be attempted casually; the route must be decided after clinical assessment and appropriate safety measures.

Correct answer: B. Enteral tube feeding

Explanation: When oral intake is impossible or inadequate but the gastrointestinal tract is functioning, enteral tube feeding may be considered because it delivers nutrients into the working gut. It can help maintain intestinal function and provide balanced nutrition. The actual tube and formula must be selected by the healthcare team after assessing swallowing, aspiration risk, digestion, medical needs, and expected duration of support.

Correct answer: A. It is given through vein route

Explanation: Parenteral nutrition delivers nutrients directly into the bloodstream through a venous catheter, bypassing the gastrointestinal tract. Because the bloodstream is accessed, strict aseptic technique, correct formulation, careful infusion, and monitoring are essential. Infection, glucose or electrolyte disturbances, and catheter complications can be serious. It is therefore administered under qualified medical supervision rather than like ordinary oral food.

Correct answer: A. To keep tube clean and meet fluid needs

Explanation: Water may be prescribed to flush the feeding tube and help prevent blockage, and it may also contribute to the patient’s daily fluid requirement. The amount and timing must be based on the healthcare plan because some patients have restrictions due to kidney, heart, or other conditions. Water should not be given casually or used to replace the complete nutritional formula.

Correct answer: C. Doctor and nutrition expert team

Explanation: Changing from oral to enteral or parenteral feeding, or changing between tube routes, requires assessment of the patient’s diagnosis, swallowing safety, gastrointestinal function, nutritional status, risks, and treatment goals. The decision is made by the responsible healthcare team, which may include a doctor, dietitian or nutrition expert, nurse, and other specialists. It should never be based on a neighbour’s or shopkeeper’s opinion.

Correct answer: A. Oral route may be safe and adequate

Explanation: If the patient can swallow safely and obtain adequate energy, protein, fluids, and other nutrients by mouth, oral feeding may meet the nutritional need without an invasive tube. Tube feeding is considered when oral intake is unsafe, insufficient, or impossible. The decision still depends on clinical assessment, because apparent eating ability does not always mean swallowing is safe or intake is adequate.

Correct answer: A. Abdominal cramps, nausea, or vomiting may occur

Explanation: A tube feed delivered faster than prescribed can exceed the stomach or intestine’s ability to tolerate the volume and rate. Feed intolerance may appear as abdominal cramps, nausea, bloating, reflux, or vomiting, and rapid feeding can increase aspiration risk. The feed should therefore be given at the ordered rate while monitoring the patient and reporting concerning symptoms to the healthcare team.

Correct answer: C. To record the amount given, time and the patient's response

Explanation: Accurate documentation records the formula or water given, volume, time, rate, route, tolerance, and relevant patient responses. Notes about vomiting, diarrhoea, abdominal distension, pain, or blockage help the healthcare team identify complications and adjust the feeding plan. Documentation also supports continuity of care and accountability. Its purpose is not to conceal feed or change its colour.

Correct answer: D. Stop the feed and inform the healthcare team

Explanation: Vomiting or abdominal bloating during tube feeding may indicate intolerance, excessive rate or volume, reflux, obstruction, or another gastrointestinal problem. The feed should be stopped temporarily and the healthcare team informed promptly so the patient can be assessed and aspiration risk reduced. The person should not independently increase the rate or continue feeding without advice. Further action must follow the clinical protocol.

Correct answer: A. Because consciousness can affect swallowing safety

Explanation: Consciousness affects a person’s ability to understand instructions, coordinate swallowing, and protect the airway through coughing and other reflexes. Reduced consciousness can make oral feeding unsafe and increase the risk of choking or aspiration. Therefore, consciousness is considered along with swallowing assessment, gastrointestinal function, and nutritional needs before choosing oral, enteral, or parenteral support.

Correct answer: A. Forcefully push the feed

Explanation: A blocked feeding tube should never be forcefully flushed or pushed because excessive pressure can damage the tube, dislodge it, or injure the gastrointestinal tract. Feeding should be paused and the healthcare professional informed. The team may check the tube position, formula consistency, kinks, and approved flushing procedure. Only trained staff should attempt troubleshooting, and sharp objects or unprescribed substances must not be used.

Correct answer: C. Food may get stuck in the throat

Explanation: Conscious swallowing requires coordinated control of the mouth, throat, and airway. An unconscious patient may have weak or absent protective reflexes and difficulty directing food safely into the oesophagus. Food can therefore lodge in the throat or enter the airway, causing choking or aspiration. Oral feeding should be avoided or supervised according to professional medical advice.

Correct answer: A. Patient's medical condition and ability to take food

Explanation: The feeding route must be selected from the patient’s medical condition and ability to take food safely and adequately. Assessment includes swallowing, gastrointestinal function, consciousness, nutritional requirements, and the expected duration of support. Plate colour, kitchen decoration, and advertising have no clinical role in route selection.

Correct answer: B. Enteral tube feeding

Explanation: When the gastrointestinal tract is functioning but oral intake is insufficient, enteral tube feeding is generally considered. It delivers a nutritionally complete formula into the stomach or intestine while preserving use of the gut. Parenteral nutrition is reserved for situations in which the gut cannot be used or cannot meet needs.

Correct answer: C. Aspiration risk may increase

Explanation: Severe swallowing difficulty can prevent food and liquid from moving safely into the oesophagus. Instead, material may enter the airway, producing choking, coughing, or aspiration pneumonia. Therefore, oral feeding should be assessed and modified by appropriate professionals; an alternative route or altered consistency may be needed for safety.

Correct answer: D. When gut feeding is not possible or adequate

Explanation: Parenteral nutrition is considered when nutrition cannot be delivered through the gastrointestinal tract or enteral feeding cannot provide enough support. Nutrients are infused into a vein, so this method requires careful prescription, sterile handling, and monitoring of glucose, fluids, electrolytes, and infection risk. It is not a routine choice for normal eating.

Correct answer: A. To prevent feeding into wrong place

Explanation: Checking the position of a nasogastric tube helps ensure that its tip is in the intended digestive location before feed or medicine is given. A misplaced tube may allow material to enter the airway, causing serious aspiration. Verification must follow approved clinical procedures; appearance alone is not a reliable safety check.

Correct answer: B. To reduce reflux and aspiration risk

Explanation: Keeping the patient’s head and upper body elevated during tube feeding uses gravity to help the feed move toward the stomach and reduces the chance of reflux. If refluxed material reaches the airway, aspiration may occur. Positioning should follow clinical instructions and should be maintained for the recommended period after feeding.

Correct answer: C. When enough oral intake is not possible for a long time

Explanation: A gastrostomy provides enteral nutrition directly into the stomach through an opening made through the abdominal wall. It may be useful when adequate oral intake is expected to be impossible for a prolonged period and the gastrointestinal tract can still function. It is not required for temporary hunger or ordinary feeding preferences.
