Feeding routes

Correct answer: A. Because nutrition is given in a controlled amount through a vein

Explanation: Parenteral nutrition delivers fluid, glucose, amino acids, electrolytes, and sometimes minerals directly into the circulation. An unsuitable prescription or changing illness can cause dehydration, fluid overload, or electrolyte disturbances. Regular clinical and laboratory monitoring allows timely adjustment, so option A is correct.

Correct answer: A. Safe or adequate nutrition is not achieved through the oral route

Explanation: Tube feeding is considered when oral intake cannot safely or adequately meet nutritional and fluid requirements. Causes may include unsafe swallowing, severe weakness, impaired consciousness, or insufficient intake despite support. The decision should follow assessment and clinical advice; aesthetic preferences are irrelevant. Hence, option A is correct.

Correct answer: B. Unsafe swallowing or aspiration risk

Explanation: Repeated coughing during eating may indicate that food or liquid is entering the airway or that swallowing is poorly coordinated. This raises concern about aspiration and possible respiratory complications. The patient should be assessed by an appropriate professional before continuing unrestricted oral feeding. Thus, option B is correct.

Correct answer: A. To reduce tube blockage and medicine-feed mixing problems

Explanation: Flushing with the prescribed compatible fluid before and after tube medication helps clear the lumen, reduce blockage, and limit unwanted contact between medicines and formula. Medicines should not be mixed casually with feed because interactions or altered absorption may occur. The procedure must follow clinical instructions, so option A is correct.

Correct answer: A. Maintaining correct hygiene, volume, rate, position, and tube care

Explanation: Family training enables caregivers to prepare and store feed hygienically, administer the prescribed volume and rate, position the patient safely, flush and care for the tube, and recognise warning signs. These skills reduce infection, aspiration, blockage, and feeding errors. Therefore, option A describes the central purpose of training.

Correct answer: A. When prolonged or higher-level nutrition support is required

Explanation: Central venous parenteral nutrition may be considered when the gastrointestinal tract cannot be used adequately or when prolonged, concentrated or higher-volume nutrition support is required. It is a specialist decision because catheter infection, thrombosis, glucose, electrolyte and liver complications must be monitored carefully. Thus, option A is correct.

Correct answer: A. Cooperation, consciousness and safe swallowing may be affected

Explanation: Mental state influences alertness, cooperation, posture control and the ability to follow swallowing instructions. Reduced consciousness or confusion may weaken protective airway reflexes and increase aspiration risk, making oral feeding unsafe. A complete assessment helps select oral, enteral or another route appropriately. Hence, option A is correct.

Correct answer: A. There may be a risk of aspiration and unsafe swallowing

Explanation: A semi-conscious patient may have a reduced swallowing reflex, poor control of secretions, weak coughing and difficulty maintaining an upright posture. Food or liquid can therefore enter the airway instead of the oesophagus, causing aspiration and respiratory complications. Swallowing safety must be assessed before oral feeding, so A is correct.

Correct answer: A. Record of intake, tolerance, weight and complications

Explanation: A route change should be based on objective monitoring rather than convenience or appearance. Intake records show what was actually received; tolerance notes identify vomiting, diarrhoea or aspiration; weight and clinical findings indicate nutritional response; complication records show safety. Together these data support a justified, individualized decision, so A is correct.

Correct answer: A. Expert review of feeding position, rate and route

Explanation: Repeated aspiration is a serious warning that the current feeding plan may be unsafe. The patient requires prompt clinical assessment, including positioning, tube location, swallowing ability, feed rate and volume, gastric tolerance and possible need for another route. Feeding should not simply be accelerated or ignored. Therefore, option A is correct.

Correct answer: A. Digestive tolerance, aspiration risk and medical condition

Explanation: The choice between gastric and jejunal access depends on gastrointestinal function, gastric emptying, aspiration risk, the patient's diagnosis, expected duration of feeding and relevant clinical constraints. Jejunal delivery may be considered in selected situations when gastric feeding is poorly tolerated, but the decision requires professional assessment. Hence, option A is correct.

Correct answer: A. The cause, rate, volume, position and tolerance should first be reviewed

Explanation: Vomiting is not normal to ignore, but the correct response depends on its cause and severity. The team should assess feed rate and volume, patient position, tube status, gastric tolerance, medications and other clinical factors, while protecting the airway. Further feeding decisions require professional judgment, so A is correct.

Correct answer: A. Return of gut function, safe swallowing and nutrition tolerance

Explanation: Transition away from parenteral nutrition should be considered when the gastrointestinal tract is functioning adequately, oral swallowing is safe if oral feeding is planned, and enteral or oral nutrition is tolerated. The change is usually gradual, with intake, hydration, laboratory values and complications monitored by the clinical team. Thus, option A is correct.

Correct answer: A. For infection, fluid, electrolyte and nutrition monitoring

Explanation: Long-term parenteral nutrition requires coordinated monitoring because nutrients bypass the gut and are delivered through venous access. The team must assess catheter infection, glucose control, fluid balance, electrolytes, liver function, micronutrients, weight and adequacy of the prescription. Nurses, physicians, dietitians and pharmacists may all contribute, so A is correct.

Correct answer: A. Food may enter the airway through the wrong passage

Explanation: Aspiration occurs when food, liquid or secretions enter the airway instead of passing safely into the oesophagus and stomach. It can cause choking, airway obstruction, pneumonia and serious respiratory compromise. Assessing consciousness, swallowing, posture, cough and feeding tolerance helps the team choose a safer route and method. Therefore, option A is correct.

Correct answer: B. Assess swallowing safety

Explanation: Coughing repeatedly during or after meals may indicate dysphagia or aspiration risk, even when oral intake is possible. The first priority is a professional swallowing-safety assessment. The result helps determine whether oral feeding can continue safely, needs modification, or requires another route.

Correct answer: C. Enteral tube feeding

Explanation: When the gastrointestinal tract is functioning but the patient cannot consume enough by mouth, enteral tube feeding can provide formula directly into the stomach or intestine. It supports nutrition while using the functioning gut. Oral intake should not simply be continued if it remains inadequate, and nutrition should not be stopped.

Correct answer: D. Parenteral nutrition

Explanation: Parenteral nutrition is considered when the gastrointestinal tract cannot be used adequately for digestion or absorption. Nutrients are supplied through a sterile intravenous route, bypassing the gut. Nasogastric and gastrostomy feeding are both enteral methods, so they still depend on gastrointestinal function.

Correct answer: A. Check correct tube position

Explanation: Before feeding, the position of a nasogastric tube must be verified according to approved clinical protocol. Feeding through a misplaced tube can deliver formula into the airway and cause serious aspiration, respiratory injury, or infection. Colour, sugar, and leaving the patient unattended do not establish tube safety.

Correct answer: B. Gastrostomy

Explanation: For a prolonged need for enteral nutrition, a gastrostomy may be considered because the tube enters the stomach through an opening in the abdominal wall. It can avoid the discomfort and visibility of a long-term nasal tube. The exact choice requires clinical assessment, consent, and professional placement.

Correct answer: C. Tube blockage

Explanation: Particles or poorly prepared formula can obstruct the narrow lumen of a feeding tube, interrupting nutrition and making medication administration difficult. Appropriate liquid consistency, proper preparation, and flushing according to protocol help reduce blockage. A particle-filled feed does not improve appetite or become sterile automatically.

Correct answer: D. Reflux or aspiration

Explanation: Keeping the head and upper body elevated during and after tube feeding helps reduce regurgitation and the chance that feed will enter the airway. Lying flat can promote reflux, which may lead to aspiration and respiratory complications. Positioning is therefore an important part of feeding safety.

Correct answer: A. Volume, rate, and tolerance

Explanation: Bolus feeding delivers a relatively larger amount over a shorter period, so the volume and administration rate can strongly affect tolerance. Discomfort should prompt review of the prescribed amount, speed, formula, position, symptoms, and clinical status rather than attention to appearance or advertising.

Correct answer: B. When the patient tolerates the feed better at a slow, controlled rate

Explanation: Continuous enteral feeding delivers formula gradually, commonly with a pump, at a slow and controlled rate. It may suit a patient who cannot tolerate a large bolus but does better with smaller amounts delivered over time. A large volume in a short period describes bolus feeding, not continuous feeding.

Correct answer: C. Because it goes directly through the vein

Explanation: Parenteral nutrition enters the bloodstream through an intravenous route, bypassing the protective barriers of the digestive tract. If the solution or equipment is contaminated, microorganisms can produce a serious bloodstream infection or sepsis. Strict sterile preparation and handling are therefore essential for patient safety.
