Chapter 7 Safe Medication Administration

Transdermal Patches • Precautions in their use relate to where the patch must be applied, how long it is to stay on and examination for local skin reaction to the adhesive that secures the patch • Many people are sensative to transdermal patch adhesives a rash may appear when a patch is used for the first time or even after repeated use • Inflammed skin will not absorb well inflammation can cause acute discomfort

Insulin Syringe

Under 30 units of insulin - 30 unit syringe 40-50 units of insulin - 50 unit syringe Anything above 50 units of insulin - 100 unit syringe
