Study Notes
IV Insertion and Extravasation
- IV insertion angle should be 35-45 degrees.
- Extravasation is the unintentional escape or leakage of an irritating agent from a vessel, causing blistering in surrounding tissue.
- Signs and symptoms of extravasation include:
- Swelling at the site (with or without pain)
- Sluggish or absent flow rate
- Continued IV flow after occlusion of the vein above the insertion site
- Patient reports of tightness, burning, and pain around the IV site
Insulin
- Insulin is a protein hormone that binds with the cell membrane and increases absorption of glucose.
- Insulin regulates the speed of carrier proteins moving glucose into cells.
- Insulin helps regulate cellular potassium levels.
- Insulin and epinephrine help the sodium-potassium pump operate.
- Insulin lowers blood glucose levels.
Insulin and Glucagon
- Insulin and glucagon are two competing hormones.
- Insulin lowers blood glucose levels, while glucagon raises blood glucose levels.
- The balance between insulin and glucagon helps the body achieve homeostasis.
Agonist
- An agonist is a group of medications that initiates or alters cellular activity by attaching to receptor sites, prompting a cellular response.
Medication Schedules
- Knowledge of medication schedules is important for proper treatment.
