week 8 - IV infusion meds and PICC line meds Flashcards
what is the catheter size determined by?
outer diameter (OD) of the catheter
in regards to catheters describe the French size
- superior to gauge system
- begins at 0
- each increment of 1 French unit represents an increase of 1/3 (0.33)mm in outer diameter
How do you measure a PICC without visible markings?
measure from the hub to the insertion site
How do you measure a PICC with visible markings starting at 0?
measure from 0 to the insertion site
What are some examples of CVAD/ PICC complications?
- catheter occlusion
- embolism
- catheter related infection (local or systemic)
- pneumothorax
- catheter migration
- arrhythmia
What causes a catheter occlusion?
- clamped/ kinked catheter
- tip against wall of vessel
- thrombosis
- precipitate buildup in lumen
what are the signs/ symptoms of a catheter occlusion?
- sluggish infusion/ aspiration
- unable to infuse/ aspirate
what are some interventions for a catheter occlusion?
- instruct patient to change positions, raise arm, cough
- assess for/ alleviate clamping/ kinking
- flush c NS 10mL do not force
- fluoroscopy to determine cause
- anticoagulant/ thrombolytic agents
What causes an embolism?
- catheter breaking
- dislodgement of thrombus
- entry of air into circulation
what are the signs/ symptoms of an embolism?
- chest pain
- respiratory distress
- hypotension
- tachycardia
what are some interventions for an embolism?
- administer oxygen
- clamp catheter
- place patient on left side c head down (air embolism)
- notify physician
What causes a catheter-related infection (local or systemic)?
- contamination during insertion/ use
- migration of organisms along catheter
- immunosuppressed client
what are the signs/ symptoms of a catheter-related infection (local or systemic)?
local
- redness
- tenderness
- purulent drainage
- warmth
- edema
systemic
- fever
- chills
- malaise
what are some interventions for a local catheter-related infection?
- culture of drainage from site
- warm/ moist compresses
- catheter removal if indicated
what are some interventions for a systemic catheter-related infection?
- blood cultures
- antibiotic therapy
- antipyretic therapy
- catheter removal if indicated
What causes a pneumothorax?
- inadvertent puncture of the lung at the time of inserting needle into vein
what are the signs/ symptoms of a pneumothorax?
- decreased/ absent breath sounds
- respiratory distress
- chest pain
- distended bilateral chest
what are some interventions for a pneumothorax?
- administer oxygen
- position in semi-flower position
- prepare for chest tube insertion
What causes a catheter migration?
- improper suturing
- insertion site trauma
- changes in intrathoracic pressure
- forceful catheter flushing
what are the signs/ symptoms of a Catheter migration?
- sluggish infusion/ aspiration
- edema of chest/ neck during infusion
- client complaint of gurgling in ear
- dysrhythmias
- increased external catheter length
what are some interventions for a Catheter migration?
- fluoroscopy to verify position
- assist with removal and new CVAD placement
What causes an arrhythmia?
line advances into right atrium irritating heart
what are the signs/ symptoms of an arrhythmia?
- palpitations/ pounding in chest
- tachycardia/ bradycardia
- chest pain/ discomfort
- SOB
- weakness, fatigue, dizziness
what are some interventions for an arrhythmia?
- medications
- vasovagal maneuvers
- cardioversion/ defibrillation
- catheter procedure
- pacemaker
- heart surgery
