Feeding routes

Correct answer: D. Into the jejunum, a part of the small intestine

Explanation: A nasojejunal (NJ) feeding tube is inserted through the nose, passes through the pharynx and stomach, and ends in the jejunum, which is the middle section of the small intestine. It delivers liquid nutrition directly into the intestine for enteral feeding when ordinary oral feeding is difficult or unsafe. It does not deliver food into the mouth, onto the skin, or into a blood vessel; therefore, option D is correct.

Correct answer: A. Enteral is through gut and parenteral through vein

Explanation: The defining distinction is the route by which nutrients enter the body. Enteral nutrition uses the gastrointestinal tract, either orally or through a tube into the stomach or intestine. Parenteral nutrition bypasses the gut and delivers nutrients into a vein. This route-based distinction helps guide safe clinical decisions.

Correct answer: B. Small frequent nutritious oral meals

Explanation: If oral feeding is safe but the patient cannot tolerate a large meal, small frequent meals can reduce fatigue and improve total intake. Meals may be energy- and protein-dense, with suitable texture and assistance as required. More invasive enteral or parenteral support should be considered only after assessment shows that oral intake remains inadequate.

Correct answer: C. Vomiting or abdominal discomfort may occur

Explanation: A feeding rate that is too rapid may exceed the patient’s gastric or intestinal tolerance. It can cause nausea, vomiting, abdominal cramps, bloating, reflux, or diarrhoea and may increase aspiration risk. The rate and volume should therefore be prescribed and adjusted according to symptoms, clinical condition, and professional monitoring rather than increased automatically.

Correct answer: D. To prevent tube blockage

Explanation: Straining removes lumps, fibres, and large particles that could obstruct a feeding tube. A blocked tube can interrupt nutrition and medication delivery and may require professional intervention. In modern practice, prescribed commercial formulas are commonly used, but whenever a suitable liquid preparation is ordered, its consistency and preparation must be appropriate for the tube.

Correct answer: A. Feed slowly in a safe position

Explanation: During assisted oral feeding, the patient should be positioned safely, usually upright as appropriate, and offered small amounts slowly while swallowing is observed. This helps reduce choking and aspiration. The caregiver should stop if coughing, wet voice, breathlessness, or distress occurs and should follow the patient’s assessed texture and supervision plan.

Correct answer: A. Because nutrition is given through vein route

Explanation: Parenteral nutrition enters the bloodstream through a venous catheter, so microorganisms introduced during preparation or handling can cause a serious bloodstream infection. Strict hand hygiene, aseptic technique, sterile equipment, correct storage, and monitoring of the catheter site are essential. This is why parenteral nutrition must be administered under trained medical supervision.

Correct answer: C. Review swallowing safety

Explanation: Repeated coughing during oral intake can be a warning sign of dysphagia or aspiration. Feeding should not be made faster or continued without assessment. The patient’s posture, food and liquid consistency, alertness, swallowing technique, and need for referral to a qualified swallowing professional should be reviewed before deciding whether oral feeding remains safe.

Correct answer: D. Small intestine

Explanation: A jejunostomy tube is placed through the abdominal wall so that its tip lies in the jejunum, a section of the small intestine. Nutrition delivered through it is enteral because it enters the gastrointestinal tract. It is not intravenous feeding, and the abdominal opening is only the access site, not the place where nutrients are absorbed.

Correct answer: A. Need to assess feeding tolerance

Explanation: Bloating and vomiting may indicate intolerance to enteral feeding, although other causes must also be considered. The healthcare team should review the feed rate, volume, formula, hydration, bowel function, medical condition, and, when indicated, tube position. Increasing the rate or stopping monitoring without assessment could worsen risk and delay appropriate treatment.

Correct answer: A. It can use the digestive tract

Explanation: Enteral feeding provides nutrients through the gastrointestinal tract. It may be given orally or through a tube that ends in the stomach or intestine, depending on the patient’s ability to swallow and the clinical need. Because the gut is used, digestion and absorption occur through the digestive system, unlike parenteral feeding through a vein.

Correct answer: A. When the digestive tract is working and can be used

Explanation: When the gastrointestinal tract is functional and safe to use, enteral nutrition is generally preferred because it supports normal intestinal digestion and absorption and avoids many risks associated with intravenous nutrition. The final choice still depends on the patient’s condition, tolerance, nutritional requirements, and professional assessment. A nonfunctional gut may require parenteral support.

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

Explanation: Flushing a feeding tube with the prescribed water helps clear residual formula or medicine and maintain tube patency. It can reduce the chance of blockage and supports reliable delivery of nutrition and medications. The amount and timing must follow the care plan because fluid restrictions, kidney disease, or other conditions may require individual adjustment.

Correct answer: A. When patient has difficulty chewing or swallowing

Explanation: Food consistency may need to be changed when chewing or swallowing is difficult. Soft, minced, mashed, or appropriately thickened food can sometimes make oral intake safer and more manageable, but the correct texture must be prescribed after assessment. Altering consistency does not remove the need to observe for coughing, choking, wet voice, or other aspiration signs.

Correct answer: A. Because very cold or hot feed may cause discomfort

Explanation: Feed temperature is considered because an excessively hot or cold preparation may cause discomfort, nausea, cramping, or poor tolerance. A suitable, prescribed temperature can make administration more comfortable, although temperature alone does not make a feed safe. Formula handling, hygiene, rate, volume, and the patient’s clinical condition must also be checked.

Correct answer: A. Along with safety and medical need

Explanation: Patient preference is an important part of patient-centred care, but it cannot override clinical safety. The feeding route must be selected after considering swallowing ability, digestive function, nutritional requirements, risks, and the prescribed treatment. The patient's informed choice should be respected whenever the available options are medically safe and suitable.

Correct answer: A. The patient cannot obtain adequate nutrition through safe oral intake

Explanation: Tube feeding may be considered when a patient cannot safely consume enough food by mouth, for example because of impaired swallowing, reduced consciousness, or severe illness. The decision requires professional assessment of aspiration risk, gut function, nutritional needs, and expected duration; a cosmetic preference is not a valid reason.

Correct answer: A. Because nutrients and fluids are given directly into a vein

Explanation: Parenteral nutrition enters the bloodstream rather than passing through the digestive tract. Therefore, errors in fluid volume, glucose, sodium, potassium, or other electrolytes can quickly produce serious complications. Regular monitoring helps the clinical team adjust the prescription and prevent dehydration, fluid overload, or dangerous biochemical imbalance.

Correct answer: A. To follow correct hygiene, volume, rate, and patient position

Explanation: Home caregivers need practical training because incorrect tube-feeding technique can cause contamination, tube blockage, vomiting, aspiration, dehydration, or inadequate nutrition. They should learn hand hygiene, preparation and storage of feed, prescribed volume and rate, correct positioning, tube flushing, warning signs, and when to contact a healthcare professional.

Correct answer: A. The patient's nutritional needs and tolerance

Explanation: Enteral-feed volume is individualized. The dietitian and medical team consider energy and protein requirements, fluid needs, age, body size, medical condition, gastrointestinal function, prescribed concentration, and the patient's tolerance. Tolerance is assessed through symptoms such as nausea, vomiting, abdominal distension, diarrhoea, and discomfort, not by appearance or advertising.

Correct answer: A. Review feeding tolerance and investigate the cause

Explanation: Diarrhoea during enteral feeding should be assessed rather than managed by automatically removing the tube. Possible causes include excessive rate or volume, unsuitable formula, contamination, medicines such as antibiotics or laxatives, infection, or an underlying illness. The healthcare team should review hydration, the prescription, hygiene, medications, and warning signs.

Correct answer: A. The patient's chewing and swallowing ability

Explanation: Texture modification during oral feeding is based mainly on the patient's chewing, swallowing, alertness, and risk of aspiration. A speech-language professional or healthcare team may recommend soft, minced, puréed, or thickened food. The suitable texture promotes safe swallowing and adequate intake; plate appearance and kitchen colour have no clinical role.

Correct answer: A. Because it requires special medical supervision and uses the venous route

Explanation: Parenteral nutrition is specialized support delivered into a vein, not ordinary food consumed by mouth. Its composition, infusion rate, sterility, fluid volume, glucose, electrolytes, and nutrient balance require professional prescription and monitoring. Complications may include infection, metabolic disturbances, and fluid problems, so it is used only when clinically indicated.

Correct answer: A. Gastrostomy enters the stomach through an abdominal opening, whereas nasogastric feeding goes from the nose to the stomach

Explanation: Both gastrostomy and nasogastric feeding are enteral methods because the feed enters the stomach and uses the gastrointestinal tract. A gastrostomy tube passes through a surgically created opening in the abdominal wall, whereas a nasogastric tube passes through the nose and oesophagus. The choice depends on clinical condition, duration, and suitability.

Correct answer: A. A short-term need

Explanation: Nasogastric feeding is commonly selected for a short-term or temporary enteral requirement, although the exact duration depends on the patient's condition and clinical guidance. If enteral support is expected to continue for a longer period, a gastrostomy or another suitable route may be considered. The decision is individualized and medically supervised.
