Feeding routes

Correct answer: C. Increase nutrient density and give oral supplements

Explanation: When swallowing is safe, the first approach is often to improve oral intake rather than automatically stopping oral food or inserting a tube. A dietitian may increase nutrient density, offer small frequent meals, adjust texture and taste, and use prescribed oral nutritional supplements. Intake and tolerance must then be monitored to see whether targets are reached.

Correct answer: D. Inadequate nutrition, aspiration, infection or intolerance

Explanation: An inappropriate route can fail to meet energy, protein, and fluid needs or can expose the patient to preventable harm. Examples include aspiration with respiratory complications, infection related to tubes or catheters, gastrointestinal intolerance, fluid imbalance, and inadequate delivery of prescribed nutrition. Route selection therefore requires clinical and nutritional assessment.

Correct answer: A. Hydration is still needed if the patient cannot speak or is tube fed

Explanation: Thirst is an unreliable measure in illness because a patient may be unconscious, confused, unable to communicate, or receiving nutrition through a tube. Fluid needs are estimated from clinical condition, losses, renal and cardiac status, feed composition, and prescribed hydration. Water may also be required for tube flushing, but the total amount must be professionally planned.

Correct answer: B. Head elevation, tube-position check and controlled rate

Explanation: Aspiration prevention requires several coordinated safety measures rather than one isolated action. The patient is generally positioned with the upper body elevated as prescribed, tube placement and external markings are checked according to protocol, and the feed is delivered at the prescribed controlled rate. Monitoring for coughing, breathing difficulty, vomiting, or reduced consciousness is also essential.

Correct answer: C. Because medical condition and nutrition plan both need coordination

Explanation: Feeding-route selection combines medical safety with nutritional planning. The doctor evaluates diagnosis, organ function, swallowing, aspiration risk, and indications or contraindications, while the dietitian estimates nutrient and fluid requirements and selects an appropriate formula and schedule. Their communication supports a route that is safe, feasible, and nutritionally adequate.

Correct answer: D. The risk of contamination and infection may increase

Explanation: Once prepared or exposed to handling and room temperature, feed can support microbial growth, especially when storage and time limits are ignored. Repeatedly using leftovers may cause contamination, diarrhoea, vomiting, systemic infection, or worsening intolerance. Caregivers should follow the product’s storage instructions, use clean equipment, discard unsafe remnants, and seek professional advice when uncertain.

Correct answer: A. To increase nutrition safely while checking tolerance

Explanation: A gradual transition allows the patient’s gastrointestinal function, swallowing, intake, and tolerance to be tested while nutritional support is maintained. The new route or oral intake is increased step by step, and the previous support is reduced only when targets are being met safely. This lowers the risk of underfeeding, vomiting, aspiration, metabolic disturbance, and treatment failure.

Correct answer: A. When the patient tolerates low volume but has a higher energy need

Explanation: Increasing energy density can provide more calories in a smaller volume, which may help a patient who cannot tolerate large volumes but has substantial energy requirements. However, the formula change must be prescribed and monitored because concentrated feeds can affect osmolality, fluid balance, gastrointestinal tolerance, and hydration. Protein, micronutrients, and water provision must also remain adequate.

Correct answer: A. To avoid conflict or blockage between medicine and nutrition delivery

Explanation: Changing from oral to enteral or parenteral support can alter how medicines are administered and absorbed. Some medicines should not be crushed, mixed with formula, or given through certain tubes; others require a specific route, timing, dilution, or flushing procedure. Reviewing the medication plan helps prevent tube blockage, reduced drug effectiveness, incompatibility, and dosing errors.

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

Explanation: Repeated blockage indicates that the cause should be investigated rather than ignored or worsened. The team reviews feed viscosity and preparation, medication administration, tube position and patency, flushing volume and timing, and whether unsuitable particles or mixing are involved. Correction must follow professional protocol; forceful flushing or unapproved tube manipulation can injure the patient or damage the tube.

Correct answer: A. To understand the nutritional effect and possible imbalance

Explanation: Weight records show whether the patient is maintaining, gaining, or losing body mass, while laboratory tests help assess glucose, electrolytes, fluid balance, kidney function, liver function, and other biochemical effects. Parenteral nutrition bypasses the digestive tract, so careful monitoring is essential to detect deficiencies, excesses, metabolic complications, and the need for adjustment.

Correct answer: A. Improve food preference, amount, and nutrient density

Explanation: A safe oral route is generally preferred when it can meet needs. Before changing to tube feeding, the team should assess appetite, food preferences, meal frequency, texture, portion size, nutrient density, symptoms, and assistance at mealtimes. Fortifying food or offering smaller frequent meals may improve intake while preserving normal eating and avoiding an unnecessary invasive route.

Correct answer: C. Feed volume, administration rate, patient position, and feed tolerance

Explanation: Repeated vomiting may result from excessive volume, a rapid administration rate, unsuitable formula, delayed gastric emptying, poor positioning, or general feed intolerance. The healthcare team should review these factors together, including abdominal symptoms and aspiration risk. Looking only at colour, smell, brand, or bedding does not identify the important clinical causes or ensure patient safety.

Correct answer: C. A sign of unsafe swallowing

Explanation: A wet or gurgly voice after swallowing and coughing during meals can indicate that material is not being cleared safely from the throat and may be entering the airway. These signs require prompt assessment by an appropriately trained healthcare professional. Oral feeding should not simply continue without review because aspiration can occur silently or develop into respiratory complications.

Correct answer: A. Because needs may be met through the enteral route

Explanation: If the functioning gastrointestinal tract can safely absorb enough energy, protein, fluids, and micronutrients, adding intravenous nutrition may provide no additional benefit. Parenteral nutrition is more invasive and carries risks such as catheter infection, metabolic disturbance, and liver complications. The route should therefore match actual nutritional needs and clinical indications.

Correct answer: C. Stop the feed and immediately inform the health team

Explanation: Coughing and breathlessness during tube feeding may indicate aspiration, in which formula enters or approaches the airway instead of safely reaching the digestive tract. Continuing or increasing the feed can worsen respiratory compromise. The immediate safe response is to stop feeding, maintain the patient safely, and contact the healthcare team for urgent assessment and further instructions.

Correct answer: B. Feed energy adequacy and actual intake

Explanation: Unexpected weight loss suggests that the patient may not be receiving enough usable energy or protein, even if a feeding prescription exists. The team should compare prescribed and actual delivered volumes, calculate nutrient content, check interruptions, vomiting, diarrhoea, malabsorption, fluid changes, and disease-related demands. This outcome-based review is more useful than observing tube colour or utensils.

Correct answer: A. Meet water needs through the tube as medically instructed

Explanation: When swallowing is unsafe, forcing water by mouth can cause aspiration and respiratory complications. Fluid requirements may be supplied through the feeding tube as part of the prescribed nutrition and hydration plan, including appropriate flushes when ordered. The healthcare team must consider renal or cardiac status, fluid restrictions, urine output, and all other sources before deciding the exact amount.

Correct answer: A. Causes such as volume, rate, feed type, and contamination must be reviewed

Explanation: Diarrhoea during tube feeding has several possible causes, including excessive rate or volume, formula composition, lactose or medication effects, contamination, antibiotics, infection, or the underlying illness. Stopping nutrition without assessment may worsen inadequate intake. The team should evaluate hydration, stool pattern, medicines, feed preparation, actual delivery, and clinical status before making a safe, cause-based adjustment.

Correct answer: A. Consider gradual enteral or oral nutrition when clinically safe

Explanation: When the gastrointestinal tract becomes functional and the patient can safely use it, the healthcare team may consider a gradual transition from parenteral nutrition to enteral or oral feeding. The change depends on swallowing safety, gut function, clinical stability, and nutritional requirements. Parenteral nutrition should not be stopped suddenly without a planned assessment.

Correct answer: A. A swallowing problem or dysphagia

Explanation: Repeatedly feeling that food sticks in the throat may indicate dysphagia, an impaired or unsafe swallowing process. It can increase the risk of choking, aspiration, and inadequate intake. The patient should be assessed by the appropriate healthcare professionals before oral feeding is continued or modified.

Correct answer: A. Supplementary enteral tube feeding with safe oral intake

Explanation: When swallowing is safe but oral intake does not provide enough energy, protein, or other nutrients, supplementary enteral tube feeding may be combined with oral feeding. This preserves the patient’s ability to eat while correcting nutritional deficits. The plan must be individualized and monitored by the healthcare team.

Correct answer: A. Consciousness, swallowing ability, gastrointestinal function, and nutritional needs differ between patients

Explanation: A diagnosis does not describe every factor relevant to nutrition support. Patients with the same disease may differ in consciousness, swallowing safety, aspiration risk, gastrointestinal function, severity, and nutrient requirements. Therefore, the route must be selected after an individualized clinical and nutritional assessment rather than from the disease label alone.

Correct answer: A. It uses the intravenous route and requires medical monitoring

Explanation: Parenteral nutrition delivers nutrients directly into the bloodstream through an intravenous catheter, bypassing the digestive tract. It requires a carefully formulated solution, sterile handling, monitoring of glucose and electrolytes, and observation for catheter or metabolic complications. It is therefore a medical therapy, not an ordinary household diet.

Correct answer: A. To reduce infection and contamination

Explanation: Tube feeding can introduce microorganisms directly into the patient’s gastrointestinal tract. Contaminated formula, containers, syringes, connectors, or hands can cause gastrointestinal infection and serious illness. Safe preparation, hand hygiene, clean equipment, correct storage, and appropriate replacement of supplies reduce contamination and protect the patient.
