Six Rights of Drug Administration | Right Drug, Right dose, Right drug by right route, right drug at the right time, right drug to the right patient. & Three Checks. |
Synergism | one drug increases the action of another |
Medication Interaction | the effect of two meds combined is greater than the effects of the meds when given seperately. |
Peak action | occurs when the highest blood or plasma concentration of drug is achieved |
The length of time the drug exerts pharmacologic effect is the | duration |
Adverse effect | very undesirable effects with more serious consequences |
Absorption | refers to the passage of medication molecules into the blood from the side of admin |
absorption is affected by | route of admi, ability of med to dissolve, blood flow to area of absorption, body surface area, lipid solubility of the med, presence of food in tummy |
Unit dose system is considered | the safest. |
Not taking medications as prescribed is common and is called | noncompliance. Often pts may not understand why they need the meds. |
Reasons for Noncompliance | side effects, cost, just plain don't like taking it! |
Using the nursing process to help the noncompliant people: ASSESS | medication reconciliation, look for allergies or other contraindications, look at the MAR, physical impairments.. |
Using the nursing process to help the noncompliant people: DIAGNOSE | deficient knowledge or noncompliance |
Using the nursing process to help the noncompliant people: PLAN | verbalize understanding of why they are taking meds, list adverse effects, take all meds. |
STAT | immediately and only once |
NOW | after the STATs givfe the "NOW"s |
PRN | Give as needed |
Routine | usually scheduled per the policy of the institution. Nurses have a 30 minute window to give the routine meds. Sometimes referred to as standing orders. |
Medication Orders | medication order lists the drug name and directions for its administration. |
Who writes medication orders? | Physicians and dentists write med orders. |
Advanced practice nurses and nurse practitioners can | write medication orders if legally designated by state statutes. |
Prescribers role: | writes an order on a form in the pts medical record, in an order book, on a legal prescription pad, or though a computer terminal. |
TO or VO are given when written or electronic communications between the prescriber and the | nurse is not possible. The prescriber will countersign the order at a later time, usually within 24h. |
Clients name, Date and time order is written, Drug name, Dose, Route, Frequency, and Signature are all part of | a medication order. |
Nurses never implement a questionable med order until after consulting with the | person who as written the order. |
Timely documentation prevents | medication erros |
Documentation demonstrates implementation of the | medication order. |
if a nurse withholds a medication, he or she | documents its omission according to agency policy. |
Circle the time of administration the | medication is withheld. |
The reason for the omission is documented in the | comment section or in the client's record. |
As soon as the medication error is recognized the nurse check's the | clients condition and reports the mistake to the prescriber and the nursing super. |

Nasal applications | topical applications are dropped or sprayed within the nose. Proper instillation is important to avoid displacing med into nearby structures such as the back of the throat. Warn pt of rebound effect. |
Sublingual Application | drug placed under the tongue and is left to dissolve slowly and become absorbed by the rich blood supply in the area. |
Buccal application | drug placed against the mucous membranes of the inner cheek. |
Vaginal application | topical vaginal applications are used to treat local infections. Early and appropo self treatment restores normal tissue integrity. |

anaphylaxis is a type of allergic reaction in which the | immune system responds to otherwise harmless substances from the environment. may begin within minutes or even seconds of exposure. rapidly progress to cause airway constriction, skin and intestinal irritation, and altered heart rhythms. |
Considered the safest IM injection site to avoid damage to nerves or blood vessels in adults | ventrogluteal |
The IM site of choice for infants younger than 12 months | vastus lateralis |
For children older than 13 months of age there are two different IM sites to choose from... | vastus lateralis or ventrogluteal can be used |
When you open a multidose vial of med what should you do? | date it! if you find one not dated, discard it. |
Intramuscular injection route | 90 degrees |
Up to 3 mL can be safely injected in the | ventrogluteal, vastus lateralis, and rectus femoris sites in any pt. larger amounts may be given in one injection in a large adult muscle in some instances (see agency policy) |
For most intramuscular injections the nurse would aspirate for | blood before injecting the mdication, to avoid injecting directly into a blood vessel. |
Ways to decrease injection discomfort | apply ice pack before, use smallest needle, select site free of inflammation, lesions, or bony prominces and without large vessels or nerves. assume prone position with the feet turned inward or sims to relax muscles. allow alcohol time to dry. |
Critical nursing responsibilites when administering a parenteral drug are to check for | allergy to the drug prior to administration and to observe the pt for 30 mins after the drug has been given for the first time. |
