Advanced IV Therapy Nursing

  1. List special considerations for the geriatric patient with advanced IVs
    • Risk for fluid volume overload r/t
    •  - decreased fluid needs
    •  - Decreased cardiac and renal reserves
    •  - tx for dehydration 
    • Increased risk for toxicity r/t decreased renal clearance
    • Will need smaller gauge catheters d/t sensitive/fragile skin
    •  - Be careful of removing dressings as well
  2. What are mechanism of action (pros) of IVs?
    • Works faster w/ rapid therapeutic peak
    • Also stops working sooner, allowing for precise titration and rapid d/c w/ adverse effects occuring
    • wide distribution
  3. What are some recognitions for an Air Embolism?
    Cardiac signs?
    What is Mill Wheel Murmur
    Resp signs?
    Others
    • Central line with needleless connector loose or missing
    • Cardiac: Tachycardia, palpitations, JVD, CP
    • Mill Wheel Murmur: machinery-like, churning, splashing sounds 
    • Resp: Dyspnea, tachypnea, wheezes and/or crackles
    • Others: Mental status change, increased anxiety
  4. If you hear a loud churning sound (mill wheel murmur), what does it suggest? What should you immediately do?
    • Mill wheel murmur: an air embolism.
    • You must immediately roll the patient onto the left side with the head down (trendelenburg) to decrease risk of cerebral air embolism or a pulmonary artery
  5. List Air Embolism Interventions
    • Trendelenburg on LEFT side 
    • VS: call rapid response if severely compromised

    2. What will you instruct the patient to do?
    3. What will you do if pulling cath out takes longer than one breath?
    4. What do you do after removing line?
    • 1. Supine or Trendelenburg if tolerated
    • 2. Instruct patient to do a valsalva meneuver
    • 3. If taking longer than one breath to pull cath, stop, aply pressure while pt. inhales, then continue again
    • 4. After removing, apply pressure and apply an occlusive dressing. Leave in place for 24 hours.
  7. List response times of each drug route
    • IV: within several mins
    • IM: 10-15 mins
    • Subq: 20-30 mins
    • Sublingual: Rapid
    • PO: 20-40 mins
  8. These 4 drug types will typically work better with IV route than the other routes
    • abx
    • corticosteroids
    • anticancer chemotherapeutics
    • Emergency cardiac meds
  9. List disadvantages of IV route
    • Interactions or Incompatibilities with multiple drugs
    • Speed shock, delivering too fast
    • Extravasaion w/ vesicant drugs (leaking of meds and damaging surrounding tissue)
    • Chemical phlebitis from infusates
  10. Why is it important to label vials/synringes?
    So you don't mix up the med if carrying multiple

    • Aseptic technique and standard precautions
    • No compatibility issues
    • 9 rights acknowledged
    • Common knowledge of drug being given

    List the range that is considered therapeutic. List the ranges that are considered at the lowest and highest range
    A. aPTT

    • Therapeutic: 1.5-2.3
    • Lowest: <1.2 - repeat a bolus and increase infusion rate
    • Highest: >3 - hold infusion 1 hour than decrease rate
  13. Fill in for ongoing monitoring of Heparin:

    After a dosage change, order an aPTT __a__ hours after.
    Once __b__ (#) consecutive aPTTs are within the therapeutic range, order next aPTT __c__ hours after the 2nd one.
    • a. 6 hours
    • b. 2 
    • c. 24 hours
  14. Which drug or additive can you not admix Phenytoin (anticonvulsant) with?

    • 5. reassess at peak time
    • 6. be alert to VS changes (BP or dyspnea)
    • 7. consider PCA or drip if requiring frequent pushes
  19. Why must using morphine with an epidural have to be preservative-free?
    Intravenous drugs formulated with preservatives are neurotoxic in epidural environments.
  20. 1. List acute short term uses for epidurals
    2. Chronic Long term use
    • Acute:
    •  - Procedural anesthesia
    •  - Severe acute pain management
    •  - Bolus injection or continuous infusion in PCA
    • Chronic:
    •  - Internal epidural implanted pump = severe chronic pain management
  21. List Epidural Protocols
    How often do you check RR?
    • No other narcotic analgesics during infusion and for 24 hours post single injection
    • Frequent checks of physiologic parameters (RR q30min for 1st 12 hours; then q1h for the next 12 hours)
  22. What can low dose naloxone and high dose be indicated for?

    • Site rotation: q3-5days
    • Rec. max rate: 2ml/hr
  25. Term: This device infuses medications once the tubing is unclamped that is attached to an elastic ballon holding the med.
    Elastomeric Device: it is typically used post-op tissue/nerve site or Intermittent IV abx with home care. It is portable and can be carried in a pouch or pocket (doesn't deliver via gravity) and delivers meds at a specific rate.
  26. What is an On-Q system used for? What is its benefits?
    What is its mechanism of action (how med gets into pt)
    • On-Q: an infuser (a small balloon) that delivers local anesthetic to surgical site/tissue at incision. 
    • Pro: used because it's less systemic narcotic needed, early DC, and faster post-op mobilization)
    •  - Pt. can also resume normal activities and body fxns faster than with PO narcotics.
    • MOA: it's a slow "soaking" of med post-op and continuously delivers up to 5 days, keeping the incision site numb.
  27. List causes for Hematoma
    s/s
    Prevention
    Tx
    • Causes: occurs during venipuncture or needle stick
    • s/s: ecchymoses, swelling, discomfort, cannot advance cath into vein
    • Prevention: indirect PIV insertion, apply tourniquet or use BP cuff prior to stick, use smallest gauge possible
    • tx: remove IV cath, apply light pressure, elevate extremity, apply ice to reduce swelling
  28. Phlebitis causes
    s/s
    Prevention
    tx
    • Causes: 3 main causes are mechanical when cath rubs against vein, hub not well secured, or arm flexion
    •  - 2nd cause is chemical irritation from a vesicus solution, hypertonic solution, inadequate dilution of med
    •  - 3rd cause is bacterial
    • Prevention: proper hand hygiene, maintain asepsis during stick, choose smallest cath and secure hub, slow rate or stop IV, proper dilution of med
    • tx: d/c cath, restart in other extremity, use warm compresses, consider CVAD for irritating infusions
  29. Local infection causes
    s/s
    Prevention
    tx
    • Causes: lack of hand hygiene, not changing caths placed after emergent situations (ems or ED) within 48 hours, poor care, lack of cath stabilization
    • s/s: redness, swelling, drainage, possible fever
    • prevention: strict HAND hygiene and asepsis, apply antiseptic if required, clip your hair, change IV tubings per policy, keep PIV site dry, scrub the hub
    • tx: culture PIV as ordered, remove PIV, topical antimicrobial used and abx if ordered
  30. Infiltration causes
    s/s
    prevention
    tx
    • Causes: (when IV solution escapes from vein into tissue) cath becomes dislodged, cath is too large or is unstable, too rapid infusion creating high pressure
    • s/s: gravity infusion hindered, pump occludes, no blood return, site is cool and blanched, swelling, leaking
    • prevention: avoid flexion around site, choose smallest cath, stabilize hub, use central line for irritating infusions
    • tx: d/c infusion immediately, restart elsewhere if needed, position limb for comfort, elevate limb, use warm OR cold compresses per pt toleration
  31. Extravasation (infiltration of vesicant solution)
    causes
    prevention 
    tx
    • Causes: drugs including vasoactive drugs, electrolyte solutions, and some abx
    • prevention: Nurse expertise when handling special meds (eg. chemo-certified nurses), use long term VADs and central lines for vesicant solutions infusing >30-60 mins
    • tx: notify MD stat, leave IV in place, position limb for comfort, elevate as tolderated, use warm/cold compress per pt comfort and toleration (as indicated for specific vesicant agents)
  32. T or F: you can use PIV for short term chemo pushes/IVPBs that are not older than 48 hours
    False: may not be older than 24 hours to use with short-term chemo
  33. List first interventions for Extravasation treatment
    • Notify MD stat
    • Leave IV in place
    • Attempt to withdraw as much fluid/med from the area as possible by aspiration at the IV hub
    • administer prescribed antidote
    • lastly, remove IV cath
  34. IV sepsis causes?
    s/s?
    prevention
    tx
    • Causes: 90% of cases are from central lines, especially subclavians, organisms primarily from pt's own skin flora
    • s/s: fluctuating fever, cold sweats, tachycardia, increased resp, mental status change, low urine output
    • prevention: use dwell time according to policy and remove if needed, ALWAYS scrub hub and use aseptic techniques, no ointments, use chlorhexidine bath
    • tx: get blood cultures, IV fluids, broad spectrum abx
  35. Speed shock s/s
    prevention
    tx
    • s/s: dizziness, facial flushing, H/A, tightness in chest, hypotension, irregular pulse, progression of syncope
    • tx: D/C drug, activate rapid response, start maintenance fluids TKO rate, give antidote, document interventions
