N210 Week 3 Lab NGT & Elimination/Bowel/Bladder

  1. 1. Discuss reasons for nasogastric intubation
    • • Is inserted through the nose and into the stomach
    • • Gaining access to stomach and its contents
    • • Once NG tube is placed, it can deliver food and medicine directly to the stomach or remove substance from it
    • • NG tubing is often used to deliver food and medicine to a patient when they are unable to eat or swallow
    • • NG tubing may be used to remove poisonous substances and remove contents of the stomach for testing or analysis
  2. Describe the process of nasogastric tube insertion and removal including equipment needed. (Taylor pg. 2353)
    • • Nasogastric tube insertion: Look at Video Skill Notes
    • • Removal of Nasogastric tube: Need tissues, 50-mL syringe, non-sterile gloves, additional PPE, stethoscope, disposable plastic bag, bath towel or disposable pad, normal saline solution for irrigation (optional), emesis brain
    • Check medical record for the order for removal of the NG tube
    • Perform hand hygiene and put on PPE
    • Identify patient
    • Explain procedure to patient and why this intervention is warranted, few moments of discomfort
    • Maintain privacy and lift bed to working level with a 30-degree position.
    • Place disposable pad across the patient’s chest
    • Give tissues and the emesis basin to the patient
    • Put on gloves
    • Discontinue suction and separate the tube from the suction.
    • Unpin the tube from patient’s gown and carefully remove the adhesive tape
    • Check placement and attach syringe and flush with 10 mL of water
    • Clamp tube with fingers by doubling tube on itself
    • Instruct the patient to take a deep breath and hold it. Quickly/carefully remove the tube while the patient holds breath
    • Coil tube in the disposable pad as you remove it from the patient
    • Dispose of the tube per facility policy.
    • Remove gloves. Perform hand hygiene
    • Remove equipment and lower bed
    • Put on gloves and measure the amount of nasogastric drainage in the collection device. Record the measurement on the output flow record, subtracting irrigant fluids if necessary
    • Add a solidifying agent to the nasogastric drainage and dispose of the drainage according to facility policy
    • After tube is removed, provide for oral hygiene to remove disagreeable tastes and odors
  3. Describe various methods to check placement of a nasogastric tube
    • • Ensures that the tip of the tube is situated in the stomach or intestine, preventing inadvertent administration of substances into the wrong place
    • • An old technique of auscultation of air injected into a feeding tube has provide unreliable and may result in tragic consequences if used as an indicator of tube placement
    • • Radiographic Examination
    • • This is the standard procedure to verify initial placement of a feeding tube
    • • This however, exposes the patient to radiation, must be interpreted by a physician, are costly if done on a routine basis and may be inaccessible
    • • Only confirms the position of the tube at the time it was taken so the tube may have been moved at any point thereafter.
    • • Placement must be checked frequently while the tube is in place
    • • Measurement of Aspirate pH and Visual Assessment of Aspirate (Taylor pg. 1226-1227)
    • • Measuring with pH of the aspirate
    • • When continuous feedings are in use, pH becomes less helpful because the nutritional formula buffers and the pH of gastrointestinal secretions
    • • Aspiration of fluid thought the feeding tubes is difficult for smaller diameter tube because they are less rigid. They may be more likely to collapse when negative pressure is applied during aspiration. More than likely, the difficulty is from the blocked tube.
    • • If repeated instillations of 30 mL of air and repositioning prove ineffective, tube placement should be checked by radiograph after obtaining an order from the primary care provider
    • • Measurement of Tube Length and measurement of Tube Marking
    • • Before each feeding, check tube length and compare findings with the initial measurement in conduction with pH measurement and visual assessment of aspirate.
    • • Any increase in length of the exposed tube may indicate dislodgement
    • • Marking the tube with an indelible marker at the nostril and then assessing this marking each time the tube is used ensure that the tube has not become displaced
    • • Carbon Dioxide Monitoring
    • • To determine nasogastric tube position and/or dislodgement has been evaluated
    • • This involves the use of a capnograph to detect the presence of carbon dioxide which indicate tube positioning in the patient’s airway
    • • However, the carbon dioxide sensor cannot determine where a feeding tube’s tip ends in the GI tract
    • • Confirming Nasointestinal Tube Placement
    • • After an initial x-ray for placement, the nurse can validate that the tube is still in the small intestine by checking the pH of the aspirate (pH is greater and equal to 6 and bi-stained, ranging in color from light to golden yellow or brownish-green)
  4. Discuss nursing interventions related to promoting patient comfort and maintaining a nasogastric tube.
    • • Promoting Patient Safety
    • • Check tube placement before administering any fluids, medications, or feeding
    • • Check gastric residual (feeding remaining in the stomach) before each feeding or every 4-6 hrs during continuous feeding
    • • Assess the abdomen for abnormalities. Assess for bowel sounds at least once per shift to check for the presence of peristalsis and a functional intestinal tract.
    • • Make sure patient is upright as possible during feeding to 30 degrees
    • • Prevent contamination during enteral feedings by maintaining the integrity of the feeding system and using proper technique. Closed systems consist of sterile, prefilled, ready to hang container, reduce the opportunity for bacterial contamination of the feeding formula. An open system exists when formula from a can or bottle is added to a feeding set up
    • • Medications may be administered through a feeding tube, but never give them while a feeding is being infused. Administer liquid forms of medications whenever possible. Never add medications directly to the formula; some drugs become ineffective when mixed with feeding formulas; medications mixed in feeding formulas may cause clogging of the feeding tube. It is very important to flush the tube with water before, between, and after the administration of medications
    • • Monitoring for Complications
    • • Prevent tubs from being clogged or obstructed
    • • After checking placement, flush tube with 30 to 50 mL of water before and after each feeding or introduction of medications, at least every 4 hours during a continuous feeding, and after aspirating a tube for gastric contents. After flushing the tube, be sure to document the amount on the intake and output record. Use feeding pump to prevent clogging. If an occlusion occurs, use a 60-mL syringe containing 30 to 60 mL of warm water to unclog the tube
    • • Providing comfort measures
    • • Irritation to nasal and throat mucosa and drying of the oral mucous membranes
    • • Administer oral hygiene frequently (every 2-4 hours)
    • • Keep nares clean
    • • Help control local irritation from the tube in the throat
    • • Encourage the patient to verbalize concerns about tube feeding
    • • Ensure that the tube is secured to the patient’s nose and gown to prevent tension and tug on the table, which causes trauma to the nares and potential displacement.
    • • Providing Instructions
    • • Provide patient and family with individualized instructions in written form as a reference for the patient and caregivers
    • • Information about the administration of feedings, operation of pump, rate, checking tube placement, and what happens when dislodged
    • • Care of tube insertion site
    • • Proper preparation, cleaning, disposable equipment
    • • Emergency phone number
    • • Arrangements of follow-up from home health care nurse as soon as possible after discharge
  5. Compare and contrast the Salem sump and Levin gastric tubes (Taylor pg.1370)
    • • Salem Sump
    • o Double-lumen tubes
    • o One lumen empties the stomach and the other provides for a continuous flow of air. The airflow lumen controls suction by preventing the drainage lumen from pulling stomach mucosa into the tube’s openings and irritating the stomach lining.
    • • Levine Gastric Tube
    • o Common single-lumen tube
    • o Lacks a venting system, and mucosal damage can occur when suction are applied continuously. So it is applied intermittently
  6. Discuss the steps to discontinuing an nasogastric tube
    o Refer to #2 REMOVAL OF NGT TUBE
  7. Discuss reasons for nasogastric and gastric intubation (Internet source)
    • o Nasogastric and gastric intubation is needed if patient…
    • • is unable to meet nutritional needs through oral intake of an adequate diet
    • • is too weak to eat food orally
    • • is comatose
    • • has neck or facial injuries, or recent surgeries
    • • Is breathing on a mechanical ventilator
    • • Is a premature infant
  8. Describe the process of administering a continuous and intermittent nasogastric and gastrostomy tube feeding. (pp. 1229 Taylor)
    • Continuous Feeding
    • • Allow gradual introduction of the formula into the GI tract, promoting maximal absoprtion
    • • Require use of an external feeding pump, which limits pt. mobility and increases cost
    • • Controversial because of the risk for reflux and aspiration
    • Intermittent Feeding
    • • Deliver at regular intervals in equal portions
    • • Introduces the formula gradually over a set period of time via gravity or a feeding pump
    • • Resemble a more normal pattern of intake and allow patient freedom of movement between feedings
    • Gastronomy (tube)
    • • Used for long period nutritional support
    • • Surgically inserted in the stomach (gastro = stomach)
    •  Less likely to regurgitate and aspirate if NG tubes were used
  9. Demonstrate the process of administering a water bolus via an NGT or gastrostomy feeding tube.

    • Procedure - Bolus Tube Feeding
    • Wash hands.
    • Assess abdomen for distention.
    • Elevate head of bed to at least 30 degrees.
    • Measure residual every 4 hours (if residual is more than 200 ml or other specifically ordered amount, hold for one hour and recheck; if it still remains high notify doctor).
    • Reinstall residual.
    • Insert 60 ml syringe into port and pour feeding product into syringe.
    • Add formula to drain by gravity.
    • Add more formula until the desired amount is infused.
    • Flush with 50 ml (or amount ordered by doctor) of water.
    • Cap the tube.
    • Remain in upright position for at least one hour after feeding.
