What is the purpose of diluting liquids used for enteral administration?

• A. Additional dilution to minimize tube occlusion and adverse effects
• B. To increase taste
• C. To shorten hang time
• D. To reduce potency

Answer: (A)

Diluting liquids used for enteral administration primarily helps prevent tube occlusion and reduce irritation or adverse effects from concentrated formulations. Small-bore feeding tubes are susceptible to clogging when viscous or concentrated liquids flow through; lowering viscosity and the concentration makes the solution flow more easily, decreasing the chance that residues will deposit and block the tube. Dilution also lessens the osmolar load and local irritation to the GI tract, improving tolerance and reducing symptoms like nausea or cramping. In practice, the goal is to deliver the same dose safely by using an appropriate diluent and flushing before and after to maintain patency. The other ideas—enhancing taste, shortening hang time, or simply reducing potency—do not reflect the primary purpose of diluting enteral liquids.
