One medication can have multiple trade names (Tylenol, Tempra). Toxic effects Medications can have specific risks and manifestations of toxicity. For example, nurses monitor clients taking digoxin for dysrhythmias, a manifestation of cardiotoxicity. Hypokalemia places these clients at greater risk for digoxin toxicity.

For example, giving the immediately. For example, a stat prescription instructs the beta‑blocker atenolol concurrently with the calcium nurse to administer digoxin 0.125 mg IV bolus stat. channel blocker nifedipine helps prevent reflex tachycardia. Medications can also increase or decrease the actions of Now prescriptions other medications, and food can interact beneficially or A now prescription is only for administration once, but up harmfully with medications. to 90 min from when the nurse received the prescription. For example, a now prescription instructs the nurse to Precautions, contraindications administer vancomycin 1 g intermittent IV bolus now. These are conditions (diseases, age, pregnancy, lactation) that make it risky or completely unsafe for clients to take PRN prescriptions specific medications. For example, tetracyclines can stain A PRN (pro re nata) prescription specifies at what dosage, what developing teeth; therefore, children younger than 8 years frequency, and under what conditions a nurse can administer should not take these medications. Another example is the medication. The nurse uses clinical judgment to that heart failure is a contraindication for labetalol, an determine the client’s need for the medication. For example, antihypertensive medication. a PRN prescription instructs the nurse to administer morphine 2 mg IV bolus every hour PRN for chest pain. Preparation, dosage, administration It is important to know any specific considerations for Other prescriptions preparation, safe dosages, and how to administer the Providers might write prescriptions for specific medication. For example, morphine is available in many circumstances or for specific units. For example, a critical different formulations.

Clients who have chronic severe pain (with cancer) generally take oral doses of morphine. COMPONENTS OF A MEDICATION PRESCRIPTION MEDICATION PRESCRIPTIONS The client’s full name Each facility has written policies for medication prescriptions, The date and time of the prescription including which providers can write, receive, and transcribe The name of the medication (generic or brand) medication prescriptions. The strength and dosage of the medication The route of administration The time and frequency of administration: exact times TYPES OF MEDICATION PRESCRIPTIONS or number of times per day (according to the facility’s policy or the specific qualities of the medication) Routine or standing prescriptions The quantity to dispense and the number of refills A routine or standing prescription identifies medications The signature of the prescribing provider nurses give on a regular schedule with or without a termination date. Without a termination date, the prescription will be in effect until the provider COMMUNICATING discontinues it or discharges the client. MEDICATION PRESCRIPTIONS Providers must re‑prescribe some medications (opioids Origin of medication prescriptions and antibiotics) within a specific amount of time or they will automatically discontinue. Providers or nurses who take verbal or telephone prescriptions from a provider write medication Single or one‑time prescriptions prescriptions on the client’s medical record. If the nurse writes a medication prescription on the client’s A single or one‑time prescription is for administration once medical record, the facility’s policy specifies how much at a specific time or as soon as possible. These prescriptions time the provider has to sign the prescription. Nurses are common for preoperative or preprocedural medications. transcribe medication prescriptions onto the medication For example, a one‑time prescription instructs the nurse to administration record (MAR). administer warfarin 5 mg PO at 1700. 278 CHAPTER 47 Safe Medication Administration and Error Reduction CONTENT MASTERY SERIES  View Video: Safe Administration of Medications Taking a telephone prescription RIGHTS OF SAFE Only when absolutely necessary MEDICATION ADMINISTRATION Ensure that the prescription is complete and correct by Right client reading it back to the provider: the client’s name, the name of the medication, the dosage, the time to give it, Verify clients’ identification before each medication the frequency, and the route. administration.

The most common routes of administration are oral, topical, subcutaneous, intramuscular (IM), and intravenous (IV). Additional administration routes include sublingual, buccal, intradermal, transdermal, epidural, inhalation, nasal, ophthalmic, otic, rectal, vaginal, intraosseous, and via enteral tubes. Select the correct preparation for the route the provider prescribed (otic vs. ophthalmic topical ointment or drops).

Pharmacology textbooks Professional journals Right client education Physicians’ Desk Reference (PDR) Professional websites Inform clients about the medication: its purpose, Pharmacists what to expect, how to take it, and what to report. To individualize the teaching, determine what the clients already know about the medication, need to know about the medication, and want to know about the medication.

Question the provider about abrupt and excessive changes. Determine clients’ learning needs. Planning Identify clients’ outcomes for medication administration. Prioritize medication administration to administer critical medications first, or to know which medications need to be given prior to treatment, procedures, or meals. Implementation Avoid distractions during medication preparation (poor lighting, phones). Interruptions increase the risk of error. Prepare medications for one client at a time. Check the labels for the medication’s name and concentration. Read labels carefully. Measure doses accurately, and double‑check dosages of high‑alert medications (insulin and heparin) with a colleague. Check the medication’s expiration date. Doses are usually one to two tablets or one single‑dose vial. Question multiple tablets or vials for a single dose. Follow the rights of medication administration consistently. Take the MAR to the bedside. Only give medications that you have prepared. Encourage clients to become part of the safety net, teaching them about medications and the importance of proper identification before medication administration. Omit or delay a dose when clients question the size of the dose or the appearance of the medication. Follow correct procedures for all routes of administration. Communicate clearly both in writing and speaking. FUNDAMENTALS FOR NURSING CHAPTER 47 Safe Medication Administration and Error Reduction 281
