how to prevent infiltration and how to treat
Prevent by using the smallest catheter possible. Treatment: 1. stop infusion 2.cold compress 3.elevate 4.new IV in opposite extremity
how to treat extravasation
- stop infusion
- aspirate drug if possible
- cold compress
Prevention and treatment of Phlebitis
Prevent 1.rotate site every 96 hours (5 days) 2.avoid excessive activity with extremity Treatment 1.stop 2.Hot compress 3.new IV in opposite extremity
embolus treatment
- apply tourniquet high on extremity to limit venous flow
2. prepare for xray removal
complications of CVC
- pneumothorax
- give oxygen - Air embolism
- place in left lateral trendelenburg and administer oxygen - Lumen occlusion
- use a 10 mL syringe with a pulsing motion - Infection
- change entire infusion system, get cultures
how to prevent air embolism during CVC therapy
- have client lie flat when changing set or connectors
2. ask client to perform valsalva
complications associated with PICC line
- catheter occlusion
- reposition arm
- confirm blood return
- flush regularly - Catheter dislodges
- watch for discomfort in jaw, chest, or ears - Phlebitis
- apply heat - Catheter embolism
- Infection
TPN
- need to verify with another nurse
- daily weights and I&Os
- accu check every 4-6 hours
- dressing change every 3 days
- tubing change every 24 hours
- admin D10W if TPN is temporarily unavaiable to prevent hypoglycemia

what is the number 1 cause for venous spasm and how do fix it
the infusion is to cold therefore warm it.
who should avoid hot tubs and saunas
HTN patients
action of ACE inhibitors and ARBs
- blocks the conversion of angiotensin 1 to angiotensin 2
2. blocks the binding of angiotensin 2 to receptors
uses of ACE and ARBS
- HTN
- HF
- MI
- diabetic nephropathy
ACE precautions
- use with caution if diuretic therapy is in place
2. monitor potassium levels
side effects ACE inhibitors
- nonproductive cough
- angioedema
- should not be used after first trimester of pregnancy
interventions ace inhibitors
- captopril should be taken 1 hr BEFORE meals
- monitor BP
- treat angioedema with 0.5 mL of 1:1000 epi administered SubQ
prototypes calcium channel blockers
- nifedipine
- verapail
- diltiazem
- amlodipine
Calcium channel blocker uses
- angina and HTN
2. verapamil and diltiazem may be used for Afib, A flutter, or SVT
main sign of salicylsim
- tinnitus
- sweating
- headache
- dizziness
phenytoin can decrease the effectiveness of which drug?
oral contraceptives by stimulating hepatic medication metabolizing enzymes
people with penicillin allergies are probably also allergic to which antibiotic class
cephalosporins
risedronate interventions
Actonel
- need to remain upright atleast 30 mins after admin to minimize esophagitis
- take on empty stomach atleast 30 mins before
- drink plenty of water with medication to minimize esophagitis
what class of drug are OTC oral decongestants
Sympathomimetics
they activate the sympathetic nervous system causing constriction of blood vessels which relieves congestion. topical nasal decongestants should be limited to 5 days to prevent rebound congestion
what kind of drug is tranylcypromine
aka Parnate is a MAOI
What kind of antibiotic is Doxycycline and what is a major consideration
(Doxycin) is a tetracycline and should not be used during pregnancy b/c of its adverse effects on developing bones and teeth
Statins interventions
- Monitor Creatinine kinase (CK) and for muscle pain
- do not drink grapefruit juice
- take it at night b/c cholesterol production generally increases overnight
- minimize alcohol
- expect to take it lifelong
phenytoin interventions
- theraputic level is 10-20
- avoid calcium foods as they decrease absorption
- check for gingival hyperplasia
- report Nystagmus immediately
