medication administration Flashcards
(40 cards)
what nursing actions support safe medication administration
- Review patient allergies.
- Review and reconcile prescribed medications.
- Identify possible adverse effects of medications.
- Identify potential interactions with other medications.
- Determine route of administration.
- Determine time of administration.
- Develop patient education regarding medication administration.

what role does the nurse play in relation to educating the clients about their medications
A nurse plays a critical role in educating clients about their medications by providing clear, understandable information about the purpose, dosage, administration method, potential side effects, and interactions of each prescription
The six rights of medication administration
- Right client: Verify the client’s identity using two client identifiers. (DOB and name)
- Right medication: Confirm the name and form of the medication is correct. (transcribing and read back, MRS)
- Right dose: Check the medication you have against the order in the medical record.
- Right route of administration: Confirm the route (IV, IM, SC, etc.).
- Right time of delivery: Confirm the time the drug is to be given and the last time the drug was administered.
- Right documentation: Document the time the drug was given and any pertinent remarks.
Right to refuse
Client has the right to refuse the medication
Right assessment
Confirm that the medication is appropriate for the clients condition
- make sure to check the medication and double check for allergies
Right education
Provide adequate education addressing
what medication the client is taking, expected benefits, and side effects.
- make sure they know what to expect when taking it
Right response/evaluation
Observe the client’s response to the rug
- check for adverse reactions and if it is working
Additional safety strategies for medication administration
- checking the medication against the Medication administration Record or medication information device upon removal of the drug from the dispensing device
- checking the drug upon preparation
- checking the drug just prior to administration
Medication reconciliation
- performed anytime the care of the client is transferred from one health care professional to another, such as when a client returns or from one physical location to another
- involves reviewing the client’s current medications, then addressing omissions and duplications
- ensure continuity of care (make sure all medications are correct)
Pharmacodynamics
The study of how a drug works, its relationship to drug concentrations, and how the body responds to
Examples of pharmacodynamics
Therapeutic range
Peek blood level (highest)
Trough blood level (lowest)
Half-life (half of duration)
Onset of action (when it starts working)
Peek effect
Duration of action (how long it stays in the body)
Drug-drug interactions
The effect that two or more drugs that the client is administered have on each other
- enhance actions or block actions, increase or decrease ADR, etc).
Drug-food interactions
Effects of nutrients on the absorption, distribution, metabolism, or excretion of medications
- iron and orange juice
- warfarin and diflucin
Serious adverse drug event (ADE)
- a life-threatening reaction that requires medical intervention to prevent death or permanent disability, or congenital anomaly.
- must be reported to the FDA to improve safety outcomes, revising drug labels and warnings, and, when needed, to withdraw drugs from the market
What is a black box warning
A warning issues on medications that may produce lethal and iatrogenic results
Allergic reactions
- allergic or hypersensitivity reaction develops when the body perceived a foreign substance (medication) as an allergen, producing antibodies to counteract the allergen
- the adverse reaction produces histamines in response to tissues injury
Anaphylaxis
A severe, life-threatening reaction resulting from histamine release producing dyspnea, hypotension, and tachycardia
Steven’s-Johnson syndrome
A potentially fatal drug reaction
- develops 1-14 days following drug administration. SJS is manifested by respiratory distress, fever, chills, a diffuse fine rash, and then blisters
What is a pharmacokinetic
The study of the absorption, metabolism, distribution, and excretion of drugs in the human body
The parts to pharmacokinetics
- the dissolution of a medication is dependent upon its initial state and route of administration
- most medications are administered by the oral or enteral route, which provides for a much slower rate of absorption
- distribution is the process of drug delivery to the target organ or tissues that occurs before metabolism and excretion
Metabolism defined
Metabolism or bio transformation is the process of converting a medication to a form that is easily excreted from the body
Examples of how metabolism works
Most drugs are metabolized by the liver.
• Kidneys and sections of the small intestines may also be responsible for drug
metabolism.
• Prodrugs are inactive chemicals that are transformed through metabolism to become
active before they have therapeutic effect.
• Oral medications pass from the small intestine to the hepatic circulation via the
mesenteric vein and portal vein flowing into the liver. This is the first-pass effect,
resulting in a lower concentration of the medication in the systemic circulation.
