A nurse is caring for a 45-year-old client who underwent abdominal surgery and has a newly inserted nasogastric tube for gastric decompression. The nurse notes that the tube is draining dark green fluid and the client reports mild throat discomfort. Which nursing action should be included in the client's plan of care?

해설
Verifying NG tube placement before any administration prevents aspiration pneumonia, a critical safety priority. Other options are less immediate or potentially harmful (e.g., supine position increases aspiration risk).

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing action for a patient with a Nasogastric (NG) tube. The core principle is patient safety, specifically preventing the life-threatening complication of aspiration. While all options relate to NG tube care, one is a fundamental, non-negotiable safety check that must precede any use of the tube. The dark green drainage is typical gastric or duodenal fluid, and mild throat discomfort is common with NG tubes, but these findings do not change the primary safety protocol.

Answer Rationale: Key Point! The correct answer is Verify tube placement before administering medications or feedings. This is the single most critical nursing intervention for any patient with an NG tube. Verification (typically by checking the pH of aspirated gastric contents and/or obtaining an X-ray per policy) ensures the tube's tip is in the stomach and not in the lungs. Administering anything into a misplaced tube can cause fatal aspiration pneumonia. This action is always the priority before using the tube for any purpose.

Distractor Analysis:
  • Option 1 (Monitor electrolytes): While important for long-term management, especially with continuous suction, it is not the immediate nursing action to include in the plan of care from the scenario's starting point. Electrolyte monitoring is a collaborative medical order, not a standalone nursing action to initiate first.
  • Option 2 (Keep supine): Watch out for confusion! This is incorrect and dangerous. The supine position increases the risk of aspiration if gastric contents reflux. Patients with NG tubes should have the head of the bed elevated to at least 30 degrees (semi-Fowler's position) unless contraindicated.
  • Option 3 (Apply petroleum jelly): This is contraindicated. Petroleum-based products can damage nasal mucosa and, if the tube is dislodged, pose an aspiration risk if inhaled. Water-soluble lubricants are recommended for nares care.
Related Concepts: This integrates knowledge of tube placement verification methods (pH testing, X-ray confirmation), aspiration precautions, and appropriate nasal care. Understanding the purpose of the tube (decompression vs. feeding) also guides care priorities.

Concept Summary
ConceptKey Takeaway
NG Tube SafetyVerification of placement is the #1 priority before ANY use (meds, feeds, irrigation).
Aspiration PreventionElevate HOB (Head of Bed), verify placement, monitor for respiratory distress.
NG Tube DrainageDark green fluid is normal (gastric/duodenal). Red drainage may indicate bleeding.
Patient Comfort & Skin IntegrityUse water-soluble lubricant for nares. Secure tube to prevent tension. Provide mouth care.

Side-by-Side Comparison!
Nursing ActionCorrect / IndicatedIncorrect / ContraindicatedRationale
Verifying Tube Placement✅ BEFORE each feeding/med administration & periodically❌ Assuming placement is correct after initial insertionPrevents life-threatening aspiration. Tubes can migrate.
Patient Positioning✅ HOB elevated 30-45° (Semi-Fowler's/Fowler's)❌ Supine or flat positioningUses gravity to prevent reflux and aspiration.
Nares (Nostril) Care✅ Clean with saline, use water-soluble lubricant (e.g., K-Y Jelly)❌ Use petroleum jelly (Vaseline)Petroleum is not water-soluble, can cause tissue damage and aspiration risk.
Securing the Tube✅ Secure to nose with device/tape, then to gown❌ Taping tightly to forehead or cheekPrevents pressure ulcers and allows for slight movement with swallowing.

Anatomy, Physiology & Pharmacology Points
  • Anatomy: An NG tube passes through the nasopharynx, esophagus, and into the stomach. Incorrect placement into the trachea and lungs leads to aspiration.
  • Physiology: Gastric fluid is normally acidic (pH 1.0-4.0). Checking pH of aspirate is a primary bedside verification method. Respiratory secretions are more alkaline (pH > 6.0).
  • Pharmacology: If administering medications via the tube, they must be in liquid form or properly crushed (check if drug is crushable!). Always flush with water (15-30 mL) before and after to maintain patency and ensure delivery.

Memory Tips
  • Safety First! Think: "Verify, then Feed/Flush/Fix (meds)".
  • Positioning: "Up with the head, away from the bed!" to remember HOB elevation.
  • Lubricant: "Water for the Water-soluble" lubricant. Avoid petroleum (think: oil and water don't mix in the lungs!).

High-Frequency NCLEX Topics NG tube management is a Core and High Yield topic. The NCLEX heavily tests safety and infection control. Expect questions on:
  1. Priority action (almost always verification of placement).
  2. Correct procedure for checking placement (pH, auscultation is NOT reliable alone).
  3. Complications to monitor for (aspiration, electrolyte imbalance, tube displacement).
  4. Patient education points (report difficulty breathing, tube dislodgement).

Watch Out for Question Variations!
  • Shift from "Action" to "Finding": "The nurse aspirates fluid from an NG tube and notes a pH of 7.0. What should the nurse do next?" (Answer: Hold feeding/meds, notify provider, suspect respiratory placement).
  • Shift to Priority Complication: "A client with an NG tube develops sudden coughing and cyanosis. What is the nurse's priority?" (Answer: Check for respiratory distress/aspiration, stop any infusion, ensure airway).
  • Shift to Delegation: "Which task can the nurse delegate to an LPN/LVN regarding NG tube care?" (Answer: May include routine flushing with water after placement verified by RN, or providing mouth care - but NOT initial verification of placement).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are caring for Mr. Johnson, post-op day 1 from a bowel resection. He has a Salem Sump NG tube to low intermittent suction. The drainage is dark green, about 200 mL in the last 4 hours. He says his throat is a bit sore.

Nursing Intervention Strategy:
  1. Assessment:
    • Safety First - Verify Placement: Check facility policy. Typically, this involves:
      1. Aspirating gastric contents with a syringe.
      2. Checking the pH with a test strip. A pH < 5.0 strongly suggests gastric placement.
      3. If unable to aspirate or pH is high, do NOT use the tube. Notify the provider; an X-ray may be needed for confirmation.
    • Assess the nares for redness, excoriation, or pressure.
    • Assess the oropharynx for dryness and provide mouth care.
    • Assess respiratory status (lung sounds, SpO2, work of breathing) for signs of aspiration.
    • Monitor drainage (color, amount, consistency) every shift.
  2. Planning & Implementation:
    • Secure the Tube: Use a commercial securement device or tape to anchor it to the nose without pressure, then loop and pin excess tubing to the gown.
    • Positioning: Maintain HOB at 30-45° at all times.
    • Comfort & Skin Care:
      • Provide frequent oral care (every 2-4 hours) with mouthwash or sponge swabs.
      • Clean nares with saline swabs; apply a water-soluble lubricant.
      • Encourage throat lozenges or ice chips if allowed.
    • Patency: Irrigate the tube per order/protocol (e.g., with 30 mL of normal saline) if drainage stops or the tube seems clogged.
Patient Safety and Precautions:
  • NEVER administer anything into the tube without first confirming correct placement.
  • NEVER clamp a Salem Sump tube connected to suction for prolonged periods; it can cause pressure buildup.
  • Contraindication: Do not insert or reinsert an NG tube in patients with recent nasal, esophageal, or gastric surgery, severe facial trauma, or base of skull fracture without explicit provider orders.
  • Key Monitoring: Watch for sudden increase in abdominal distension, nausea, or respiratory distress, which could indicate tube displacement or obstruction.

Nursing Procedure & Medication Flow Steps for Administering Medication via NG Tube:
  1. Verify Placement (pH check).
  2. Check for Residual: Aspirate gastric contents. Hold feedings/notify per policy if residual is high (e.g., > 500 mL).
  3. Flush: Flush tube with 15-30 mL of warm water.
  4. Administer: Give each liquid medication separately, flushing with 5-15 mL water between each drug. If crushing pills, ensure they are crushable and mix thoroughly in water.
  5. Final Flush: Flush with another 15-30 mL of water to clear the tube.
  6. Reconnect to suction or clamp as ordered.
  7. Document: Medications given, volume of flushes, residual amount, tube placement check.

A Word from Your Senior Nurse "Remember, that NG tube is a direct pathway into your patient's stomach. We are the gatekeepers. Verifying placement isn't just a task on a checklist; it's our primary defense against a devastating complication. In clinical practice, I've seen seasoned nurses catch a misplaced tube by a simple pH check that saved a patient from a code blue. When you're studying, drill this sequence into your mind: Assess (verify), Intervene, Evaluate. On the NCLEX and at the bedside, this safety-first mindset is what defines a competent and vigilant nurse. You've got this!"
