CALCULATIONS FOR IV ADMINISTRATION
:))
Number of hours= total volume| ml/hr
gtt per min= total volume x gtt/mL in administration set| total # of minutes
6 RIGHTS OF MEDICATION ADMINISTRATION
right patient, right drug, right dose, right route, right time, right documentation
average time for drawing peak levels
1. oral intake
2. intramuscular
3. intravenous
- 1-2 hours
- 1 hour
- 30 minutes
reflect the lowest concentration or residual level and are usually obtained within 15 min prior to administration of the next scheduled dose.
The scheduled dose of medication should not be administered until the trough level is confirmed
Trough Levels
Pneumothorax (drug insertion)
prevention: use US, Avoid subclavian when possible
Air embolism
have client lie flat when changing administration set or needleless connectors; ask client to perform Valsalva Maneuver when possilbe
COMPLICATIONS ASSOC WITH PICC LINE
:)))))0
catheter occlusions
prevent kinks, reposition arm, confirm blood return, flush catheter between medications, administer approved anti-thrombolytic
Catheter dislodges
asses blood return, discomfort in jaw, chest, ear, contact hcp
phlebitis
apply low degree heat d/c if not rsolved
catheter embolism
secure catheter, avoid pulling
CARE & MAINTENANCE OF (TPN)
- VERIFY PRESCRIPTION & SOLUTION With another nurse
- administer via infusion pump
- monitor weight daily
- monitor & record I&O , noting fluid balance
- monitor serum glucose levels every 4-6 hours
- monitor signs of infection
- change dressing every 48-72 hours
- change IV tubing & fluid every 24 hours
- TPN is unavailable? administer dextrose 10% in water to prevent hypoglycemia
