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.
