Feeding routes

Correct answer: B. Stomach

Explanation: Enteral nutrition uses the gastrointestinal tract, so the stomach can be part of the route. A tube may deliver formula into the stomach, after which digestion and movement through the intestine can occur. The hair, nail, and cloth are not digestive organs and cannot serve as nutritional routes. Thus, the stomach is the only appropriate answer.

Correct answer: C. Inform the health worker immediately

Explanation: Vomiting or coughing after tube feeding may indicate intolerance, reflux, incorrect tube position, an excessive rate or volume, or aspiration risk. Feeding should not be altered casually or doubled. The symptom must be reported promptly to a healthcare worker so the patient can be assessed and the feed can be paused or adjusted safely according to instructions.

Correct answer: A. To prevent blockage and keep the tube patent

Explanation: Flushing a feeding tube with the prescribed amount of water helps remove residual formula or medicine from the tube. This reduces the chance of blockage and keeps the tube patent for the next feeding or medication. Flushing is not intended to change colour, induce sleep, or thicken the formula. The exact water volume should follow professional instructions.

Correct answer: B. Chewing and swallowing food through the mouth

Explanation: The oral route means that food or drink is taken through the mouth, chewed if necessary, and swallowed. It is the ordinary route of eating and uses the digestive tract after swallowing. Giving fluid into a vein is parenteral, delivering food directly through a tube is enteral tube feeding, and applying cream is a topical route.

Correct answer: C. The patient's illness, swallowing ability, and digestive status

Explanation: Changing a feeding route requires assessment of the patient’s illness, level of consciousness, swallowing safety, digestive function, nutritional requirements, and risk of aspiration or other complications. The healthcare team uses this information to decide whether oral, enteral-tube, or parenteral nutrition is appropriate. Wall colour, bed cost, and plate size are irrelevant.

Correct answer: D. Oral route

Explanation: When digestion is functioning and the patient can swallow safely, oral feeding is generally the simplest and most natural route. It requires no feeding tube or venous access and allows food to pass through the normal digestive process. The exact decision still depends on clinical assessment, but the given conditions clearly make the oral route the best answer.

Correct answer: A. Because it is given through a vein instead of the digestive tract

Explanation: The terms describe different routes. Enteral nutrition uses the gastrointestinal tract, either through the mouth or through a feeding tube placed into the stomach or intestine. Parenteral nutrition bypasses the gastrointestinal tract and delivers a nutrient solution intravenously through a vein. Therefore, parenteral nutrition is not classified as enteral nutrition.

Correct answer: B. Oral route

Explanation: Taste is detected by taste receptors in the mouth and is experienced when food contacts the tongue and oral tissues. Therefore, the oral route allows the patient to taste the food directly. Nutrition delivered through a vein or through gastrostomy or jejunostomy tubes does not normally place food in the mouth, although a patient may separately taste food if oral intake is permitted.

Correct answer: C. Too much or too little nutrition can cause problems

Explanation: The prescribed volume of tube feed is calculated to provide appropriate energy, protein, fluids, and other nutrients. Too little may cause undernutrition, dehydration, or inadequate recovery, while too much may cause intolerance, vomiting, fluid overload, or metabolic problems. Therefore, the amount and timing must follow the healthcare team’s instructions rather than personal guesswork.

Correct answer: D. The patient can swallow but has chewing difficulty

Explanation: If swallowing is safe but chewing is difficult, the texture of oral food can often be modified by making it soft, mashed, minced, or otherwise easier to chew. The modification must suit the patient’s assessed swallowing ability. If the digestive tract cannot be used or venous nutrition is mandatory, oral food would not be the appropriate route.

Correct answer: B. Which route was used and how the patient tolerated it

Explanation: A feeding record should document the route used, the type and amount of nutrition, timing, relevant water flushes, and the patient’s tolerance or symptoms. Recording this information supports continuity of care and helps the healthcare team identify problems and plan future feeding. Wall colour, spoon price, or a photograph alone has no clinical value.

Correct answer: A. Oral route

Explanation: Food and drinks taken through the mouth are administered by the oral route. After entering the mouth, they are chewed or prepared for swallowing and then pass through the oesophagus into the stomach and intestines. A venous route delivers nutrients into the bloodstream, a skin route acts through the skin, and the respiratory route is for breathing rather than feeding.

Correct answer: B. Parenteral nutrition

Explanation: Nutrition supplied directly into a vein, bypassing the stomach and intestines, is called parenteral nutrition. It is used when the gastrointestinal tract cannot be used or cannot provide adequate nutrition. Because it enters the bloodstream, strict aseptic technique, careful monitoring, and medical supervision are essential.

Correct answer: A. Enteral nutrition

Explanation: Tube delivery of food into the stomach or intestine is enteral nutrition because the gastrointestinal tract is still being used. A nasogastric or gastrostomy tube can provide this support when a person cannot eat enough by mouth. Parenteral nutrition is different because it enters a vein and bypasses the gut.

Correct answer: B. Chewing and swallowing safely

Explanation: Before selecting or changing a feeding route, the patient’s ability to chew and swallow safely must be assessed. Poor swallowing may allow food or liquid to enter the airway, causing choking or aspiration. The decision also considers consciousness, digestion, medical condition, and expected nutritional needs, not appearance or food preference.

Correct answer: C. Giving a nutrient solution through a vein

Explanation: Parenteral nutrition supplies nutrients through a venous catheter directly into the bloodstream, bypassing the gastrointestinal tract. It may contain glucose, amino acids, lipids, electrolytes, vitamins, and trace elements in a carefully prescribed mixture. Oral food, spoon feeding, and nasogastric feeding use the digestive tract and are therefore enteral or oral methods.

Correct answer: C. Giving feed through a nasogastric tube

Explanation: Enteral nutrition delivers nutrients into the gastrointestinal tract. A nasogastric tube passes through the nose into the stomach, so a prescribed feed given through it is enteral. Intravenous nutrition is parenteral because it enters the bloodstream, while skin cream and eye drops are not routes for nutritional support.

Correct answer: A. To deliver nutrition safely and adequately to the patient

Explanation: A feeding route is the pathway used to deliver nutrition and, when prescribed, fluids or medicines to a patient. Its selection aims to achieve adequate nourishment while minimizing risks such as aspiration, infection, metabolic imbalance, or intolerance. The route may be oral, enteral, or parenteral, depending on swallowing ability, gut function, medical needs, and patient safety.

Correct answer: A. Keep hands and equipment clean

Explanation: Hand hygiene and clean equipment are basic measures for preventing contamination during tube feeding. The caregiver should prepare feed safely, use clean containers and supplies, follow storage and time limits, keep the tube and feeding port clean, and discard feed that has been improperly stored. Reusing old feed or leaving it exposed encourages microbial growth and infection.

Correct answer: A. The oral route

Explanation: The oral route involves placing food in the mouth, chewing, swallowing, and stimulating taste and smell, so it provides the most direct experience of normal eating and appetite. Tube feeding bypasses most oral sensations, while parenteral nutrition bypasses the gastrointestinal tract entirely. Oral feeding is used only when it is safe and nutritionally adequate.

Correct answer: A. To give the correct feed to the correct patient

Explanation: Patient identification is a fundamental safety step before tube feeding. Matching the patient's identity with the prescription helps prevent administration of the wrong formula, wrong volume, wrong additives, or a feed intended for another person. Staff should use approved identifiers and check the prescribed diet, allergies, route, and timing before starting the feed.

Correct answer: D. Nose to stomach

Explanation: A nasogastric, or NG, tube is inserted through the nose and passed down the throat and oesophagus into the stomach. The word “naso” refers to the nose and “gastric” refers to the stomach. It can be used for short-term feeding, fluid administration, or removal of stomach contents, under appropriate clinical supervision.

Correct answer: A. Giving a prescribed amount at one time

Explanation: Bolus feeding means delivering a prescribed quantity of enteral formula over a relatively short period, often at scheduled intervals, rather than continuously throughout the day. The amount and rate must be ordered for the patient. Tolerance should be monitored because rapid or excessive boluses may cause fullness, cramps, reflux, nausea, or vomiting.

Correct answer: A. To reduce contamination of the feed and equipment and the risk of infection

Explanation: Hands can carry microorganisms that may contaminate the formula, containers, syringes, or tube connections during preparation and administration. Proper hand washing, clean equipment, safe water, and hygienic handling reduce the patient’s exposure to infection. Hand hygiene does not change the feed’s colour, taste, or thickness; it is an essential infection-control measure.

Correct answer: C. The digestive tract is usable

Explanation: Enteral nutrition delivers nutrients into the stomach or intestine, so the gastrointestinal tract must be sufficiently functional and usable. A large room, attractive food, or expensive utensils does not determine route suitability. Clinical assessment is still required to select the safest method and formula.
