Question 1

What are the key differences between a nasogastric tube and a percutaneous endoscopic gastrostomy tube, and how do I decide which is best?

Accepted Answer

nasogastric tube is temporary, inserted through the nose, and suitable for short-term use (days to weeks). A percutaneous endoscopic gastrostomy (PEG) tube is placed directly into the stomach through the abdominal wall and is ideal for long-term feeding (months to years). Choose PEG for chronic conditions requiring prolonged nutrition support.

Question 2

How often should I monitor blood glucose and electrolytes during total parenteral nutrition, and what targets should I aim for?

Accepted Answer

Check blood glucose every 4–6 hours and electrolytes (sodium, potassium, magnesium, calcium) daily or more frequently if unstable. Target glucose 140–180 mg/dL, sodium 135–145 mEq/L, potassium 3.5–5.0 mEq/L, magnesium 1.5–2.5 mg/dL, calcium 8.5–10.5 mg/dL. Adjust the TPN formula based on these values.

Question 3

When is it appropriate to start enteral feeding versus parenteral nutrition for a patient who can't swallow?

Accepted Answer

Enteral feeding is preferred when the gastrointestinal tract is functional, as it supports gut integrity and is less costly. Parenteral nutrition is reserved for cases where the gut is nonfunctional, severely damaged, or when enteral feeding is contraindicated. The decision is based on the patient’s ability to tolerate tube feeds and the risk of complications.

Question 4

What are the signs of infection or complications at the feeding tube site that require immediate medical attention?

Accepted Answer

Redness, swelling, pain, drainage, fever, or a foul odor around the tube insertion site are red flags for infection. Also watch for tube dislodgement, blockage, or leakage. If any of these occur, contact your healthcare provider right away.===
