You should check all injection sites for abnormalities. Additionally, you should be aware of the patient’s condition and have the patient sign a consent form if necessary.53.2 The rights of drug administration include the right patient, right drug, right dose, right route, right time, right documentation, right reason, right to know, right to refuse, and right technique.In Summary (cont.)53.3 Drugs may be administered for either local or systemic effects. Table 53-2 outlines the many drug administration routes.53.4 Oral medications typically are swallowed and absorbed through the digestive tract. Sublingual medications go under the tongue, and buccal medications go between the cheek and gum.53.5 The three most common injection routes are ID, subcut, and IM. IV is less frequently used in a medical office. All injections are given using aseptic technique. In Summary (cont.)53.6 Other medication routes include inhalants (respiratory), topical (including transdermal), urethral, vaginal, and rectal.53.7 Certain special considerations must be made when caring for pediatric, pregnant, and breastfeeding patients. Pediatric patients require extreme care when calculating doses. Checking medications given to pregnant and breastfeeding patients for possible adverse effects is essential. In Summary (cont.)53.8 Patients should be educated about why, when, and how they should take medications. This includes instruction to ensure patient compliance. Patients should also be instructed about the dangers of medication combinations, the importance of reporting an adverse effect, and maintaining a complete medication list.53.9 Documentation of medication administered should occur immediately after the given and should include the name, date, time, medication administered, dose, route, location, lot #, and how the patient tolerated it.End of Chapter 53Words are the most powerful drug used by mankind.~Rudyard Kipling
