Feeding routes

Correct answer: D. Infection or contamination

Explanation: Fever in a patient receiving tube feeding may indicate infection, contamination, aspiration-related respiratory illness, or another medical problem. The patient should be assessed promptly, and feed preparation, storage, administration technique, tube care, and other infection sources should be reviewed. Fever should never be dismissed as a cosmetic issue.

Correct answer: A. Small, frequent meals

Explanation: Small, frequent meals reduce the effort and volume required at any one sitting, so a fatigued patient may be able to consume more total energy and nutrients. Food texture and assistance can also be adjusted when appropriate. Immediate parenteral nutrition is unnecessarily invasive when safe oral intake remains possible.

Correct answer: B. Total energy and nutrient intake

Explanation: When two feeding routes are used, the energy, protein, fluids, and other nutrients from both sources must be added together and compared with the patient’s requirements. This prevents accidental underfeeding or overfeeding and helps the team adjust oral portions, tube-feed volume, and monitoring appropriately.

Correct answer: C. Reflux may increase

Explanation: Laying a patient flat immediately after tube feeding can promote reflux because stomach contents may move back toward the oesophagus. Reflux can cause discomfort and may increase the danger of aspiration into the airway. Appropriate head and upper-body elevation, as prescribed, supports safer post-feeding care.

Correct answer: D. Push forcefully

Explanation: Forcefully pushing a blocked tube can rupture or dislodge it, injure the patient, or drive an unsafe bolus into the body. The blockage should be reported and managed according to professional protocol, including checking the formula and using only an approved gentle flushing method. Force is never a safe solution.

Correct answer: A. Because nutrients are delivered through the gastrointestinal tract, where they are digested and absorbed

Explanation: Enteral nutrition places food or formula in the gastrointestinal tract through the mouth or a feeding tube. The functioning gut then performs digestion, absorption, and much of the normal nutritional processing. Direct delivery into the bloodstream describes parenteral nutrition, not enteral nutrition, so option A is correct.

Correct answer: A. Because an additional intravenous route may not be needed

Explanation: If a functioning gastrointestinal tract already receives and absorbs enough enteral nutrition, adding parenteral nutrition may provide no benefit and may expose the patient to unnecessary intravenous-catheter, infection, metabolic, and monitoring risks. The least invasive adequate method is generally preferred, subject to clinical assessment.

Correct answer: B. Giving enteral nutrition into the small intestine

Explanation: A jejunostomy is a surgically or endoscopically created access route that places a feeding tube into the jejunum, a section of the small intestine. Formula delivered through it is enteral nutrition because it uses the gastrointestinal tract. Intravenous nutrition is parenteral, while chewing and skin application are unrelated.

Correct answer: A. A gastrostomy tube enters the stomach through the abdominal wall, whereas a nasogastric tube passes through the nose and oesophagus to the stomach

Explanation: A gastrostomy tube reaches the stomach through a deliberately created opening in the abdominal wall. A nasogastric tube enters through the nose, passes down the oesophagus, and ends in the stomach. Both may provide enteral nutrition, but their entry routes and usual duration of use differ. Option B reverses them.

Correct answer: A. Feed type or concentration, volume, administration rate, and preparation hygiene

Explanation: Diarrhoea after tube feeding requires a broad review of the formula type and concentration, delivered volume, rate, timing, preparation and storage hygiene, medications, infection, and the patient’s underlying condition. A concentrated or contaminated feed, excessive volume, or rapid administration may contribute. No single factor alone is a complete assessment.

Correct answer: A. Keeping tube clear and helping fluid needs

Explanation: Water flushing has two important purposes in enteral feeding. It helps wash feed residue away from the tube, reducing the chance of blockage, and it may contribute to the patient’s prescribed fluid intake. The amount and timing must follow the healthcare professional’s instructions, because excess water may be unsafe for some patients.

Correct answer: B. Actual feed received and energy adequacy

Explanation: Weight loss during tube feeding requires checking what the patient actually received, not merely what was prescribed. Missed feeds, interruptions, vomiting, intolerance, leakage, or an inadequate formula may reduce energy and protein intake. Actual volume, calories, tolerance, and the feeding record should therefore be reviewed first.

Correct answer: A. Because it enters the body directly through a vein

Explanation: Parenteral nutrition enters the bloodstream through a vein and bypasses normal digestion. Its glucose, amino acids, lipids, electrolytes, vitamins, minerals, water, concentration, and rate must therefore be matched to the patient’s condition. An incorrect mixture can cause metabolic, fluid, or vascular complications.

Correct answer: A. Hygiene, prescribed amount and timing, and warning signs

Explanation: Home tube-feeding education must cover hand and equipment hygiene, the prescribed formula, amount, timing, position, flushing, and warning signs. Vomiting, coughing, breathing difficulty, abdominal distension, diarrhoea, leakage, or tube displacement require prompt advice. Skin care alone is necessary but not sufficient for safe care.

Correct answer: A. Contamination and infection

Explanation: Prepared enteral feed can be contaminated by microorganisms from hands, utensils, air, or the surrounding environment when it is left open. Microbial multiplication may cause gastrointestinal illness, diarrhoea, or infection, especially in vulnerable patients. Open storage does not sterilise the feed; it increases the need for hygienic preparation, covering, and timely use.

Correct answer: A. Get swallowing assessed

Explanation: A sensation of food sticking may indicate dysphagia or impaired swallowing safety. The patient should be assessed by an appropriate healthcare professional, often with a swallowing evaluation, before the texture or route of feeding is changed. Ignoring the symptom or making food harder could increase choking or aspiration risk.

Correct answer: A. Digestive tract function and tolerance

Explanation: Before returning from parenteral to enteral nutrition, the gastrointestinal tract must be sufficiently functional and able to tolerate feeding. The team considers bowel activity, symptoms, absorption, haemodynamic stability, and nutritional needs, then usually introduces enteral feed gradually while monitoring tolerance and adequacy.

Correct answer: A. Causes, safety, and correctable measures should be checked first

Explanation: Poor appetite alone does not establish that oral feeding is unsafe or impossible. The cause may be pain, nausea, medication, depression, poor meal support, or an unsuitable diet, and these factors may be treatable. Route selection should consider swallowing safety, intake, nutrition needs, gut function, and the patient’s condition.

Correct answer: A. For patient tolerance and safety

Explanation: A prescribed rate allows the patient’s stomach and intestine to receive feed at a tolerable speed. Giving it too rapidly may cause nausea, vomiting, cramping, diarrhoea, reflux, or aspiration, while an excessively slow rate may compromise nutritional delivery. The rate should be adjusted only according to clinical advice and observed tolerance.

Correct answer: A. Stop the feed and inform the health team

Explanation: Breathing difficulty during tube feeding is an urgent warning sign and may indicate aspiration, reflux, airway compromise, or another serious problem. Feeding should be stopped immediately, the patient should be kept safe and assessed, and the healthcare team should be contacted. Increasing feed or forcing water could worsen the danger.

Correct answer: A. To clear residue and reduce blockage risk

Explanation: Flushing with the prescribed water before and after medication helps clear feed or drug residue, maintains tube patency, and reduces the chance of blockage or unintended mixing. Medicines should not be mixed casually with feed because compatibility and absorption may be affected. Flushing does not change taste or increase drug effectiveness.

Correct answer: A. Feed volume, rate, formula type, and tube position

Explanation: Bloating may result from excessive volume, rapid administration, poor tolerance, an unsuitable formula, constipation, or an incorrectly positioned or malfunctioning tube. A complete assessment therefore includes the amount and rate, formula characteristics, abdominal symptoms, bowel function, patient position, and tube position. Checking only one pair of factors may miss the cause.

Correct answer: A. Consciousness can affect swallowing safety

Explanation: Consciousness affects alertness, coordination, protective cough, and the ability to follow swallowing instructions. Reduced consciousness can make oral feeding unsafe because food or fluid may enter the airway without an effective protective response. Route selection must therefore consider consciousness together with swallowing assessment and the patient’s nutritional needs.

Correct answer: A. Energy and nutrient density of the diet

Explanation: If oral swallowing is safe, the first step is usually to improve the adequacy of the oral diet rather than immediately changing the route. Energy and protein density, portion size, meal frequency, appetite, symptoms, food acceptance, and actual intake should be reviewed. A dietitian may prescribe fortification or oral supplements when appropriate.

Correct answer: A. To accurately assess adequacy of nutritional intake

Explanation: The prescribed volume may not equal the volume actually delivered because of procedures, vomiting, intolerance, leakage, blockage, or missed feeds. Recording the actual amount allows accurate assessment of energy, protein, and fluid intake and helps identify whether the feeding plan needs adjustment. It does not confirm tube placement; that requires appropriate clinical checks.
