1

Physician's orders must include..

date and time
name of drug
route
dosage
time frequency
duration, if limited
if prn, must have reason
signature

2

6 Rights of Medication Administration

Right dose
Right patient
Right Time
Right route
Right Medication
Right documentation

2 additional: right knowledge, right to refuse

3

What are the 3 checks for medication administration?

1: Check MAR against dr orders
2: Check medications agains MAR (drug, dose, route, time, expiration, allergies)
3: Check meds against MAR again in client room; ID pt, allergies, verify med with pt and MAR

4

Documenting Medications

Cross out time on MAR with single line
initial
ID initials at bottom of page
include assessment info: VS, BG, LOC, Pain level

5

Documenting held medications

circle time
and document why med was held

6

Methods for inhalers

1. Use spacer (optimal; best for steroids)
2. take a drink
shake inhaler, exhale
tilt back head slightly
hold inhaler 2 fingerbreaths from mouth
activate, breathe in slowly and deep for 3-5 seconds
hold breath 10 seconds
exhale slowly
3. NOT PREFERRED; not for steroids!!
shake, exhale, tilt head back
place inhaler in mouth, activate
breathe in slowly, hold 10 seconds

7

absorption

when the med molecules pass into the blood from site of administration

8

factors affecting absorption

route
ability to dissolve
blood flow to site
body surface area
lipid solubility

9

distribution

after absorption medication is moved to body tissues and organs

10

factors affecting distribution

physical and chemical properties of meds
physiology of person taking it
circulation
membrane permeability
protein binding
age/liver disease

11

metabolism

after med reaches site it's broken down into less active or inactive forms for easier excretion

12

factors affecting metabolism

age
liver disease

13

excretion

med exits body through kidneys, liver, bowel, lungs, exocrine glands

14

factors affecting excretion

renal impairment
liver disease
peristalsis

15

adverse effects

undesired, unintended, unpredictable response to medication
mild to severe
immediate or over time

16

Who are at most risk for adverse effects?

very young or old
women
renal/liver disease
patients with multiple meds
extremely underweight or overweight

17

side effects

predictable and often unavoidable effect produced at usual therapeutic dose

18

most common side effects

N/V
diarrhea
constipation
anorexia
drowsiness

19

anaphylactic reaction

sudden constriction of bronchiolar muscles, edema of pharynx and larynx, severe wheezing, SOB

20

synergistic effect

combined effect is greater than if meds given separately

21

trough

the lowest serum concentration of a medication before the next medication dose is administered

22

peak

time it takes to reach highest level of serum concentration of a medication

23

half-life

time it takes for excretion processes to lower amount of unchanged medication by half

24

onset

time it takes after medication is administered for it to produce a response

25

duration

time during which med is present in concentration great enough to produce response

26

buccal administration

place med in mouth against cheek
don't chew, swallow, drink
must fully dissolve against cheek
alternate cheeks

27

sublingual administration

place med under tongue and fully dissolve
don't chew, swallow, or drink

28

pharmacokinetics

study of how meds enter the body, reach site of action, metabolize, and exit the body

29

sub-q volume

0.5--1.5 mL

30

normal needle length and gauge for SQ

25g
5/8" at 45 degrees
or 1/2" at 90 degrees
