Oral Administration Easiest and most desirable route. Food sometimes affects absorption. Protect patients from aspiration. Follow special precautions when administering medications to patients with enteral or small-bore feeding tubes Follow tubing connection standards Verify tube is compatible with medication absorption Use liquid medications when possible Flush before, bet ween, and after medications Copyright © 2021, Elsevier 14Inc. All Rights Reserved. Topical Medication Applications Skin applications Ask patients if they take any topical medications. When applying a transdermal patch, ask the patient whether he or she has an existing patch. Wear disposable clean gloves when removing and applying transdermal patches. If the dressing or patch is difficult to see (e.g., clear), apply a noticeable label to the patch.

Administering Medications By Inhalation Pressurized metered-dose inhalers (pMDIs) Require hand strength and hand-breath coordination May be used with a spacer Breath-actuated metered-dose inhalers (BAIs) Release depends on strength of patient s breath on inspiration Dry powder inhalers (DPIs) Activated by patient s breath Deliver more medication to the lungs ’ ’ Copyright © 2021, Elsevier 21Inc. All Rights Reserved. Administering Medications by Irrigations Irrigations most commonly use sterile water, saline, or antiseptic solutions on the eye, ear, throat, vagina, or urinary tract.

It is administered by injection because the GI tract breaks down and destroys an oral form of insulin. Use the correct syringe: 100-Unit insulin syringe or an insulin pen to prepare U-100 insulin Insulin is classified by rate of action: Rapid-, short-, intermediate-, and long-acting Know the onset, peak, and duration for each of your patients ordered insulin doses. ’ Copyright © 2021, Elsevier 29Inc. All Rights Reserved. Parenteral Administration of Medications Mixing insulins Patients whose blood glucose levels are well controlled on a mixed-insulin dose need to maintain their individual routine when preparing and administering their insulin. Do not mix insulin with any other medications or diluents unless approved by the health care provider. Never mix insulin glargine or insulin detemir with other types of insulin. Inject rapid-acting insulins mixed with NPH insulin within 15 minutes before a meal. Verify insulin doses with another nurse while you are preparing the injection. Copyright © 2021, Elsevier 30Inc.
