Enteral Formula Administration Explained

The question asks to identify the term that describes the administration of enteral formula into the gastrointestinal tract using a pump. Let's break down the options to understand the different methods of enteral feeding.

Understanding Enteral Feeding Methods

Enteral feeding is a way to provide nutrition through the digestive tract when a person cannot eat or drink adequately. Different methods exist, varying in how the formula is delivered:

• Intermittent Drip Feeding: Formula is given at specific times throughout the day, usually over a period of 20-60 minutes. It can be administered via gravity or a feeding pump.
• Nasoenteric Tube Feeding: This refers to the route of feeding, where a tube is inserted through the nose and into the stomach or small intestine. The method of delivery (bolus, intermittent, or continuous) can vary.
• Bolus Feeding: A large amount of formula is given quickly at set intervals, often using a syringe. This method is usually faster but can sometimes cause discomfort or intolerance. It's less commonly associated with pump administration for a slow, steady delivery.
• Continuous Drip Infusion: Formula is delivered slowly and steadily over a prolonged period (e.g., 24 hours) using a feeding pump. This method mimics natural feeding patterns and is often used for patients who require consistent nutritional support or have difficulty tolerating larger volumes.

Identifying Pump Administration

The key phrase in the question is "via pump". Feeding pumps are specifically designed to control the rate and volume of formula delivery accurately over time. While pumps can be used for intermittent feeding, the term that most specifically and commonly refers to the slow, steady administration of formula over an extended period using a pump is 'Continuous drip infusion'. This method ensures a constant supply of nutrients and is gentler on the digestive system compared to bolus or even some intermittent methods.

Therefore, administering enteral formula into a gastrointestinal tract via pump, implying a controlled, steady flow, directly refers to Continuous drip infusion.

Correct Answer Analysis

Based on the definitions, Continuous drip infusion is the most fitting description for administering enteral formula using a pump for a steady, controlled delivery.
