Nutrition Basics: Feeding Tubes, Diets, and Nursing Care

By RN-Nurse | Simplified Nursing Guides for NCLEX & Practice

Nutrition is one of the most essential aspects of patient care. Whether you’re a registered nurse (RN nurse), nursing student, or preparing for the NCLEX, understanding nutrition basics — including feeding tubes, diets, and nursing care — is crucial. This guide breaks it down in a simple, easy-to-understand way that helps every nurse provide safe and effective care.


🍎 Why Nutrition Matters in Nursing

Proper nutrition helps patients heal, maintain energy, and recover faster. Nurses play a vital role in monitoring intake, preventing aspiration, and ensuring patients receive the right diet or feeding method.
In the nursing bundle and on the NCLEX, nutrition questions test your ability to recognize safe feeding practices and respond to complications.


🩺 Types of Feeding Tubes Explained

1. Nasogastric Tube (NG Tube)

  • Inserted through: Nose → esophagus → stomach.
  • Purpose: Short-term feeding, medication administration, or gastric decompression.
  • Nursing care:
    • Check tube placement before feeding (aspirate pH or x-ray confirmation).
    • Keep the head of the bed at 30–45° to prevent aspiration.
    • Flush with water before and after medications.

2. Gastrostomy Tube (G-Tube or PEG Tube)

  • Inserted directly into the stomach through the abdominal wall.
  • Purpose: Long-term nutrition.
  • Nursing care:
    • Clean the stoma daily with mild soap and water.
    • Rotate the tube gently to prevent skin breakdown.
    • Check for redness, leakage, or infection around the site.

3. Jejunostomy Tube (J-Tube)

  • Inserted into: The jejunum (part of the small intestine).
  • Used when: The stomach needs to be bypassed (e.g., gastric surgery, aspiration risk).
  • Nursing care:
    • Administer feeds slowly.
    • Do not check residuals unless ordered.
    • Flush the tube regularly to prevent clogging.

🥗 Common Diet Types in Nursing Care

NCLEX Tip: Always assess for swallowing difficulties (dysphagia) before giving oral feedings. Use a speech therapist consult if aspiration risk is suspected.


💡 Nursing Responsibilities in Nutrition Care

  1. Assess nutritional status:
    • Weight, BMI, intake/output, and lab values (albumin, prealbumin).
  2. Monitor tube feedings:
    • Ensure correct formula and rate.
    • Watch for diarrhea, nausea, or vomiting.
  3. Prevent aspiration:
    • Maintain head elevation during and 30 minutes after feeding.
    • Verify tube placement before each feed.
  4. Collaborate with dietitians:
    • Adjust diet plans for disease conditions and patient preferences.
  5. Educate patients and families:
    • Explain feeding procedures, signs of complications, and home care tips.

⚠️ Complications to Watch For

  • Aspiration pneumonia (if feeding enters lungs)
  • Tube blockage (from improper flushing)
  • Skin infection (around G-tube sites)
  • Electrolyte imbalances (especially in long-term enteral feeding)

🧠 NCLEX Nursing Tip

You may get questions like:

“A nurse is caring for a client receiving enteral feedings via NG tube. Which action is most important?”
Correct answer: Verify tube placement before administering the feeding.

This concept appears often in nursing bundles and NCLEX review exams because it’s directly tied to patient safety.


❤️ Final Thoughts

Nutrition is more than food — it’s a foundation of healing. As a nurse, your role in managing feeding tubes and diets ensures that patients recover safely and maintain their strength.
Every registered nurse (RN nurse) should be confident in providing nutritional care — it’s not just a skill, it’s a lifesaving responsibility.
