To Give A Dose Of Medication To A Patient

Administering medication to a patient is a critical task that demands precision, understanding, and unwavering attention to detail, ensuring both efficacy and safety. This comprehensive guide explores the multifaceted aspects of medication administration, from the fundamental principles to advanced techniques and crucial safety considerations.

The Foundation: Understanding Medication Administration

At its core, medication administration is a process of delivering a prescribed drug to a patient in a safe and effective manner. This involves much more than simply handing over a pill. It requires a deep understanding of pharmacology, patient-specific factors, and meticulous adherence to established protocols.

The Five (or More) Rights of Medication Administration

The cornerstone of safe medication administration is the principle of the "rights." These rights act as a checklist, ensuring that each step is verified before a medication is given. While the core five rights are widely recognized, expanding upon them adds further layers of safety:

• Right Patient: Verifying the patient's identity is paramount. Use at least two identifiers (e.g., name, date of birth, medical record number) and, when possible, ask the patient to state their name.
• Right Medication: Compare the medication label to the medication order to ensure they match exactly. Pay close attention to the drug name, strength, and dosage form.
• Right Dose: Double-check the dosage calculation, especially for high-risk medications or pediatric patients. Use appropriate measuring devices and seek verification from another healthcare professional when necessary.
• Right Route: Administer the medication via the route specified in the medication order (e.g., oral, intravenous, intramuscular, subcutaneous). Different routes have different absorption rates and potential side effects.
• Right Time: Give the medication at the prescribed time interval to maintain therapeutic blood levels. Consider factors like meal schedules and other medications that may affect absorption.
• Right Documentation: Accurately and promptly document the medication administration, including the date, time, drug name, dose, route, and any observations or patient responses.
• Right Reason: Understand the reason the patient is receiving the medication. This knowledge helps to identify potential allergies, contraindications, and adverse effects.
• Right to Refuse: Patients have the right to refuse medication. Respect their decision, assess the reasons for refusal, and educate them about the potential consequences. Document the refusal and notify the prescribing physician.
• Right Education: Provide patients with clear and understandable information about their medications, including the purpose, dosage, potential side effects, and any necessary precautions.
• Right Assessment: Before administering medication, assess the patient's condition to ensure it is safe to administer the medication. This includes vital signs, lab values, and other relevant clinical data.

Understanding Medication Orders

A medication order is a prescription written by a licensed healthcare provider that directs the administration of a specific drug to a patient. It contains essential information, including:

• Patient's Full Name and Date of Birth: Ensures the medication is intended for the correct individual.
• Date and Time of the Order: Establishes the validity and timeliness of the prescription.
• Drug Name (Generic or Brand): Specifies the exact medication to be administered. Generic names are preferred to avoid confusion.
• Dosage: Indicates the amount of medication to be given.
• Route of Administration: Specifies how the medication should be administered (e.g., oral, IV, IM, subcutaneous).
• Frequency and Timing: Defines how often and when the medication should be given (e.g., twice daily, every 6 hours, before meals).
• Indication (Reason for Medication): Provides the rationale for the medication, helping to ensure appropriateness and identify potential allergies or contraindications.
• Prescriber's Signature and Credentials: Validates the order and ensures accountability.

Any ambiguity or missing information in the medication order should be clarified with the prescriber before administration.

Routes of Medication Administration: A Detailed Overview

The route of administration significantly impacts the bioavailability and onset of action of a medication. Each route has specific considerations and techniques.

Oral Administration

Oral medications are the most common and convenient route. They are absorbed through the gastrointestinal tract.

• Tablets and Capsules: Ensure the patient can swallow the medication. If necessary, check if the medication can be crushed or opened (check with a pharmacist first). Administer with a full glass of water.
• Liquids: Use accurate measuring devices (e.g., oral syringe, calibrated cup). Ensure the patient understands the dosage markings.
• Sublingual and Buccal: Instruct the patient to place the medication under the tongue (sublingual) or between the cheek and gum (buccal) and allow it to dissolve completely. Do not chew or swallow the medication.

Parenteral Administration: Injections

Parenteral administration involves injecting medication directly into the body, bypassing the gastrointestinal tract.

• Subcutaneous (Subcut): Inject into the fatty tissue beneath the skin. Common sites include the abdomen, upper arm, and thigh. Use a short needle (typically 25-30 gauge, 3/8-5/8 inch) and inject at a 45-90 degree angle.
• Intramuscular (IM): Inject into a muscle. Common sites include the deltoid, vastus lateralis, and ventrogluteal muscles. Use a longer needle (typically 22-25 gauge, 1-1.5 inch) and inject at a 90-degree angle. Aspirate before injecting to check for blood return (not always recommended anymore, check institutional policy).
• Intravenous (IV): Inject directly into a vein. Requires specialized training and equipment. Medications are administered directly into the bloodstream, providing rapid onset of action.
• Intradermal (ID): Inject into the dermis, just below the epidermis. Used for allergy testing and TB skin tests. Use a small needle (typically 25-27 gauge, 3/8-5/8 inch) and inject at a 5-15 degree angle.

Topical Administration

Topical medications are applied directly to the skin or mucous membranes.

• Creams, Ointments, and Lotions: Apply a thin layer to the affected area. Use gloves to avoid absorption of the medication.
• Transdermal Patches: Apply to clean, dry, hairless skin. Rotate application sites to prevent skin irritation.
• Eye Drops and Ointments: Instruct the patient to tilt their head back and look up. Gently pull down the lower eyelid and instill the medication into the conjunctival sac. Avoid touching the tip of the applicator to the eye.
• Ear Drops: Warm the solution before administration. Instruct the patient to tilt their head to the side. For adults, pull the ear up and back; for children, pull the ear down and back.

Other Routes of Administration

• Inhalation: Medications are inhaled into the lungs using devices such as nebulizers, inhalers, and dry powder inhalers.
• Rectal: Medications are inserted into the rectum, where they are absorbed into the bloodstream.
• Vaginal: Medications are inserted into the vagina, where they are absorbed into the bloodstream.
