"Six Rights" of Medication Administration

Percolation

A process to extract the soluble constituents of a plant with the assistance of gravity. The material is moistened and evenly packed into a tall, slightly conical vessel; the liquid is then poured onto the material and allowed to steep for a certain length of time. A small opening is then made in the bottom, which allows the extract to slowly flow out of the vessel. The remaining plant material may be discarded. Many tinctures and liquid extracts are prepared this way.

Liniment

Extract of a plant added to either alcohol or vinegar and applied topically for therapeutic benefits.

distraction free environment, medication safety zone

Factors to prevent medication errors

excretion

In geriatric pharmacokinetics, the following affect the __________________ stage: •Renal excretion of drugs decreases with age. Changes in kidney function require dosage adjustment, especially if the drug has a narrow therapeutic range.

Infusion

A tea made by pouring water over plant material (usually dried flowers, fruit, leaves, and other parts, although fresh plant material may also be used); the mixture is then allowed to steep. The water is usually boiling, but cold infusions are also an option. May be used therapeutically; hot tea is an excellent way to administer herbs.

Decoction

A tea made from boiling plant material—usually the bark, rhizomes, roots, or other woody parts—in water. May be used therapeutically. Natural dyes are often made this way.

Poulitice

A therapeutic topical application of a soft, moist mass of plant material (such as bruised fresh herbs), usually wrapped in a fine woven cloth

culture of safety

ANA encourages "Just Culture" Individuals should be encouraged to report drug errors, so the system can be repaired and fixed. Risk management departments

Dosage forms

Always consult pharmacist, health care provider, or reliable drug source regarding crushing a drug. Do not crush extended- or sustained-release drugs

Tinctures

An extract of a plant made by soaking herbs in a dark place with a desired amount of either glycerin, alcohol, or vinegar for 2-6 weeks. The liquid is strained from the plant material and then may be used therapeutically.

Essential oils

Aromatic volatile oils extracted from the leaves, stems, flowers, and other parts of plants. Therapeutic use generally includes dilution of the highly concentrated oil.

Astragalus

Boosts immune system, Limits cold and flu symptoms not all species of ______________ are safe for human consumption; some species contain the neurotoxin swainsonine, and others contain toxic levels of selenium.

high alert medications

Can cause significant harm if given in error Examples: Epinephrine, insulin, nitroprusside, potassium chloride injection Simplify storage, preparation, and administration Improve policies and education Limit access Monitor patient's response

Dietary Supplement Health and Education Act (DSHEA)

Ensures products are safe and label information is truthful and not misleading. 1. Name of the supplement 2. Amount of the supplement (net quantity) 3. Nutrition labeling 4. Ingredient list 5. Name and place of the manufacturer, packer, or distributor "This statement has not been evaluated by the US Food and Drug Administration (FDA). This product is not intended to diagnose, treat, cure, or prevent any disease."

Herbal preparations

tablet splitting, buying drugs over the internet

Examples of safety risks for medication administration

cannabis use disorder

Drug effects- impairs short-term memory, learning, and ability to focus, and it can cause problems with balance and coordination. In addition,itincreases heart rate and may cause hallucinations, anxiety, panic attacks, and psychosis in some people. Long-term effects-chronic cough, frequent respiratory infections, and exposure to cancer-causing compounds because the smoke has many of the same irritating and lung-damaging properties as tobacco. Ingestion of the drug increases the heart rate for hours, increasing risk for heart attack and stroke.

Opiod use disorder

Effects •Euphoria, tranquility, reduced pain •Drowsiness, confusion •Nausea, constipation Dose-dependent respiratory depression

Disposal of medications

Follow specific information on drug label or insert. Transfer drug from original container to undesirable substance (i.e., kitty litter). Place mixture in container (i.e., sealed plastic bag). Remove all identifying information on label before disposing of empty container. Do not flush drugs down toilet unless specifically instructed. Return drugs to community "drug take-back" program. Consult pharmacist if any questions.

metabolism

In geriatric pharmacokinetics, the following affect the __________________ stage: •decrease in liver size and a reduction in cytochrome P450 (CYP450) enzyme activity, which is responsible for the breakdown of drugs. This can cause decrease first-pass metabolism and can prolong drug half-life, resulting in increased drug levels and potential drug toxicity

distribution

In geriatric pharmacokinetics, the following affect the __________________ stage: •decline in muscle mass and a increase in fat so lipid-soluble drugs have a greater volume of distribution, increased drug storage, reduced elimination, and a prolonged period of action. •reduction in total body water, which affects water-soluble drugs, and a reduction in albumin levels can result in decreased protein binding of drugs and increased free drug available to exert therapeutic effects, but it also increases the risk for drug toxicity.
