These learning modules are designed to provide health care workers involved with medications with basic information about the nature and administration of medications. The 30 modules are organized into six units. An overview of preparation and administration of medicines, principles of medication therapy, and medication fundamentals are presented in unit 1. The second unit covers interpreting medication orders, charting medications, and legal and ethical obligations of medication administration. Health, age, and body process; care of the aged; and handling medications are discussed in unit 3. Selected medications for the major body systems are the subject of the eight modules constituting the fourth unit. Unit 5 contains four modules devoted to medications for such special problems as inflammation, infection, and immunity; nutritional deficiencies; allergies; malignant deseases; and mental and emotional stress. The final unit covers the following techniques involved in the administration of medication: preparation and administration of oral medications; count schedules to establish accuracy of supply; application of topical medication; instilling ear, eye, and nasal medication; and inserting rectal or vaginal suppositories. Master tests for the 30 modules are also provided. (MN)
