Feeding routes

Correct answer: D. Contamination and infection

Explanation: Prepared enteral feed can support rapid microbial growth if it is stored, handled, or reused improperly. Repeatedly giving leftover feed increases contamination and infection risk and may also cause gastrointestinal intolerance. Feed should be prepared, stored, labelled, and discarded according to professional and product instructions.

Correct answer: A. Review feed viscosity, flushing technique, and tube care

Explanation: Repeated tube blockage suggests that the feed consistency, particle size, flushing practice, medication administration, or tube position may need review. The tube should not be forced or used blindly. A trained professional should assess the cause and revise the method while maintaining the patient's nutrition safely.

Correct answer: C. To determine whether total energy, protein, and fluid needs are met

Explanation: In combined feeding, oral food, oral supplements, and tube feed all contribute to the patient's daily intake. Adding these sources prevents underfeeding or accidental excess and shows whether energy, protein, and fluid targets are being achieved. The plan can then be adjusted appropriately.

Correct answer: D. To seek timely help and reduce aspiration, infection, or intolerance

Explanation: Family caregivers should know warning signs such as persistent coughing during feeds, breathing difficulty, repeated vomiting, fever, diarrhoea, abdominal distension, leakage, or tube blockage. Early recognition allows feeding to be stopped safely when necessary and professional help to be obtained promptly.

Correct answer: A. It can affect oral-intake safety and cooperation

Explanation: A reduced level of consciousness may impair attention, cooperation, airway protection, and swallowing coordination. These changes can make oral feeding unsafe and increase aspiration risk. Consciousness is therefore considered along with swallowing ability, respiratory status, and the patient's overall clinical condition.

Correct answer: B. Very cold or hot feed can cause discomfort

Explanation: Feed that is excessively hot may injure tissues, while very cold feed may cause discomfort, cramping, or poor tolerance in some patients. Checking that it is at a suitable, comfortable temperature supports acceptance and safe administration. Temperature must be considered with rate and volume.

Correct answer: C. To prevent contamination and infection

Explanation: Enteral feed enters the gastrointestinal tract and may support the growth of microorganisms if contaminated. Handwashing, clean preparation surfaces, safe water, clean equipment, correct storage, and appropriate time limits reduce contamination and infection. Hygiene is therefore a core part of safe route management.

Correct answer: D. Evaluating safety, adequacy, tolerance, and complications

Explanation: Monitoring is broader than simply recording how much feed was given. It evaluates whether the selected route is delivering adequate nutrition and fluid safely, whether the patient tolerates it, and whether complications such as aspiration, infection, metabolic disturbance, vomiting, or blockage are developing.

Correct answer: A. Both can affect patient safety and nutrition outcomes

Explanation: A feeding route must provide nutrition without creating avoidable harm. Aspiration can impair breathing and cause lung infection, while contaminated equipment or feed can cause gastrointestinal or systemic infection. Both risks reduce safety, tolerance, and nutritional effectiveness, so both are assessed together.

Correct answer: B. Review feed volume, rate, density, and the supplementation plan

Explanation: Failure to meet nutrition goals requires a structured review rather than an arbitrary change. The team should assess prescribed volume, actual delivered volume, rate, energy density, interruptions, tolerance, hydration, and possible oral supplements. The plan may then be adjusted according to the patient's condition.

Correct answer: C. Nasal or throat discomfort and reduced long-term tolerance

Explanation: A nasogastric tube may cause persistent nasal or throat irritation, discomfort, pressure injury, reflux, and difficulty with long-term acceptance. When enteral nutrition is needed for a prolonged period, the clinical team may review whether another appropriate route is safer and more comfortable for the patient.

Correct answer: D. To prevent infection and skin problems

Explanation: The gastrostomy site is an opening through the abdominal wall, so poor care can permit infection, leakage, irritation, granulation, or skin breakdown. Keeping the site clean and dry, observing redness or discharge, and reporting abnormal findings support safe feeding and early treatment of complications.

Correct answer: A. If the digestive tract is usable, the enteral route may be more natural

Explanation: When the gastrointestinal tract is functioning and safe to use, enteral nutrition supports the normal digestive pathway and may help maintain gut structure and function. It can also avoid some risks of intravenous nutrition. The final choice still depends on the patient's condition and clinical assessment.

Correct answer: B. Reduced tolerance, diarrhoea, or abdominal discomfort

Explanation: A sudden increase in concentration changes the osmotic and nutrient load delivered to the intestine. Some patients may then develop cramping, bloating, nausea, diarrhoea, or poor tolerance. Feed changes should be prescribed, introduced gradually when appropriate, and monitored for symptoms and hydration.

Correct answer: C. To keep the tube clear and support hydration

Explanation: Water flushes, when prescribed and suitable for the patient, help clear residual feed or medication from the tube and reduce blockage. They may also contribute to the patient's fluid intake. The amount and timing must be included in the care plan, especially when fluid restriction or electrolyte problems exist.

Correct answer: D. Total energy intake, tolerance, and nutrition goals

Explanation: Unexpected weight loss may indicate that delivered nutrition is inadequate, losses are increased, absorption is impaired, or the patient is not tolerating the regimen. The team should review actual intake, interruptions, energy density, symptoms, hydration, disease changes, and goals before adjusting the feeding plan.

Correct answer: B. It can be gradually reduced after assessing total nutrition needs

Explanation: When oral intake improves, the patient's oral food, supplements, and tube feed are totalled to determine whether nutritional and fluid targets are being met. If appropriate, tube feed may be reduced gradually and monitored, while ensuring that intake remains adequate and the patient remains safe.

Correct answer: C. To understand reflux and aspiration risk

Explanation: Vomiting during enteral feeding can be worsened by a flat or unsuitable position and can allow stomach contents to enter the airway. Checking position, feed rate, volume, tube status, and respiratory symptoms helps identify reflux and aspiration risk. Feeding should be managed according to clinical protocol.

Correct answer: D. Risk of tube blockage and nutritional imbalance

Explanation: A thick or poorly blended homemade mixture may contain particles that obstruct a narrow tube. Its nutrient, fluid, electrolyte, and microbial content may also be unpredictable, causing inadequate or excessive intake and infection risk. Any change from prescribed feed should be discussed with the healthcare team.

Correct answer: A. It can change route safety, tolerance, and nutritional need

Explanation: The stage and progression of disease can alter swallowing, consciousness, digestion, absorption, fluid requirements, metabolic needs, and the risk of aspiration or infection. Consequently, a route that was suitable earlier may need reassessment. Feeding decisions should follow the current clinical condition and monitoring results.

Correct answer: B. To identify signs of infection or inflammation

Explanation: The catheter site is checked during parenteral or intravenous nutrition to detect redness, warmth, swelling, pain, discharge, or other signs of infection and inflammation. Early identification allows prompt treatment and helps prevent serious bloodstream infection. Site assessment also confirms that the catheter remains secure and usable. Therefore, option B is the only medically appropriate answer; taste, chewing, and colour are unrelated to catheter safety.

Correct answer: C. To remember the correct amount, rate, hygiene, and warning signs of feeding

Explanation: Written instructions support safe feeding-route care after the patient leaves the hospital. They can record the prescribed feed, quantity, timing, administration rate, hand and equipment hygiene, storage requirements, and warning signs such as coughing, vomiting, diarrhoea, blockage, or infection. Clear written guidance reduces mistakes and helps the family provide consistent care. Thus, option C is correct.

Correct answer: A. To adjust a safe and adequate nutrition route when the patient’s condition changes

Explanation: Regular reassessment is essential because a patient’s swallowing ability, consciousness, gastrointestinal function, tolerance, hydration, and nutrient requirements may change. The safest route, feed type, amount, and rate may therefore need adjustment. Monitoring also helps identify complications such as aspiration, nausea, diarrhoea, blockage, or inadequate intake. Consequently, option A correctly describes the clinical purpose of reassessment.

Correct answer: A. Special nutrition support

Explanation: Enteral feeding provides nutrients through the gastrointestinal tract when a patient cannot eat enough by mouth but digestion and absorption are usable. It is a clinical feeding route and part of specialised nutrition support. The dietitian helps select the formula, amount, timing and monitoring plan with the healthcare team.
