LPN Therapeutic Diets and Enteral Feedings 5

Question 1

The LPN is preparing to flush a jejunostomy tube. Which solution is recommended for routine tube flushes?

Accepted Answer

Tap water (for adults with intact immune systems)

Answer

Tap water is generally acceptable for flushing feeding tubes in immunocompetent adults; sterile water is used for immunocompromised patients or jejunostomy tubes per facility policy.

Question 2

A patient with COPD requires nutritional support. Which dietary modification is most appropriate to reduce carbon dioxide production?

Accepted Answer

High-fat, lower-carbohydrate diet

Answer

High-fat, lower-carbohydrate diets reduce CO2 production from carbohydrate metabolism, which eases the respiratory burden in COPD patients.

Question 3

When initiating continuous enteral feedings, the LPN should start at what rate and advance how?

Accepted Answer

Low rate (10–20 mL/hr) and increase gradually as tolerated per orders

Answer

Starting at a low rate and advancing gradually allows the GI tract to adjust and helps prevent intolerance symptoms like nausea and diarrhea.

Question 4

A patient on a fluid-restricted diet due to hyponatremia asks if gelatin (Jell-O) is allowed. The LPN correctly responds:

Accepted Answer

No, gelatin is counted as a fluid because it is liquid at room temperature

Answer

Any food that is liquid at room temperature, including gelatin, ice cream, and ice chips, counts toward fluid restrictions.

Question 5

The LPN is caring for a patient with a new PEG tube. What is the earliest the skin around the PEG site should be cleaned?

Accepted Answer

24 hours after insertion using soap and water as ordered

Answer

PEG site care typically begins 24 hours post-insertion using soap and water to prevent infection while allowing initial healing.
