1
Q
The 8 Rights of Med Administration
A
- Right Medication
- Right Dose
- Right Time
- Right Route
- Right Client
– Always check the Pt’s ID band - Right Documentation
- Right Reason
- Right Frequency
- For refusal
2
Q
right time
A
In most instances, the medication can be considered given “on time” if administered within ½ hour prior to or ½ hour after the time ordered.
3
Q
The right documentation
A
- The right documentation refers to the charting of the time when the medication was given.
- This needs to be charted immediately after the client has taken his/her medication
- The nurse needs to witness the client taking the medication before she can sign off
- This documentation should be placed on the medication record under the correct date and time.
4
Q
The Right Reason
A
- refers to the nurses’ knowledge as to why the patient is on the medication
- The nurse verifies that the medication ordered is correct for the clients illness or diagnosis
- The nurse can refer to the CPS under “drug uses” to determine that this is an appropriate medication for the reason in which this patient is being treated
5
Q
The Right Frequency
A
- The nurse must know why a medication is ordered for certain times of the day and whether the time schedule can be altered
- Medications that must act at certain times are given priority (ie. Insulin should be given at a precise interval before a meal)
- Give medications according to their action: ie. Sleeping pills are given at bedtime whereas as diuretics are given in the morning
6
Q
Medication errors (MEs)
A
failure to complete or use the correct planned action for pnt when providing meds
7
Q
Adverse drug events (ADEs)

injury that is cb a med or failure to admin a med. May or may not cause harm to pnt
8
Q
Adverse drug reactions (ADRs)
A
injury occurring at the time a drug is used.
9

idiosyncratic
A
is a rxn that is specific to the pnt
10
Q
Two types of Adverse Drug Reactions (ADRs)

Allergic reactions
Idiosyncratic reactions
11
Q

A
.
16
Q

A
10 SECONDS
17

AIR LOCK
A
0.2mL of air IN THE NEEDLE AND IT LOCKS THE MEDICATION INSIDE.
18
Q
Ventrogluteal site
A
preferred site for adults and children over 18 months
19
Q
Vastus lateralis site
A
(preferred site for infants)
20
Q
First trimester
A
is the period of greatest danger for drug-induced developmental defects
Nausea medications
21
Q
During the last trimester
A
the greatest percentage of maternally absorbed drug gets to the fetus
22
Q
FDA classifies drugs for pregnancy according to their safety
A
Pain meds, any opioids, can cause respiratory depression. Look for apneic spaz on baby.
23
Q
Absorption
peds
A
Gastric pH less acidic (-increase abrop rate)
Gastric emptying is slowed (-peristalsis is slower)
Topical absorption faster through the skin (thin and more permeable)
Intramuscular absorption faster (-because there is more fluid) and irregular (-developing muscle)
More drug enters the brain because of the immature blood-brain barrier (-watch baby for neurological e
24
Q
Distribution
peds
A
TBW (total body water) is 70% to 80% in full-term infants, 85% in premature newborns, 64% in children 1 to 12 years of age
Greater TBW means fat content is lower
Decreased level of protein binding (more free drug in the tissues)
Immature blood-brain barrier
25
Metabolism
| peds
Liver immature, does not produce enough microsomal enzymes
Less Cytochrome P-450 enzyme is produced (necessary for metabolism of drugs) ( –the drug becomes more potent)
Older children may have increased metabolism, requiring higher doses
26
Excretion
| peds
Kidney immaturity affects glomerular filtration rate and tubular secretion (drugs not readily excreted)
Decreased perfusion rate of the kidneys
Increased susceptibility to drug overdoses and side effects as metabolites (by-products of the drugs) are not excreted
27
NEVER GIVE ASPRIN TO CHILDREN IT LINKS TO RYES SYNDROME
YOU CAN GIVE TYLONOL AND ADVIL
28
NEVER GIVE 2 Y/O A PILL
. FOR THE POTENTIAL OF ASPRIATON.
29
. The child receives a dose of 1 teaspoon per directions according to his weight of 28 lb. Later, when his 5 yr-old sister needs a dose, she receives 1.5 teaspoons because her weight is 45 lb.
If the concentration of the drug contains 160 mg per teaspoon, then how much medication (mg) did the 5 year-old receive with her dose? Change all weights to kilograms.
25/2.2=11.36* 160
?

5. What should the parents look for when evaluating the children’s response to a dose of acetaminophen
DECREASE FEVER
31
Polypharmacy
(the use of many different medications from various physicians or OTC for the same illness. They doctor shop)
32
Decreased albumin:
| geriatrics
Reduced protein, therefore higher unbound drugs resulting in enhanced symptoms (-DRUG-DRUG INTERCTIONS)
Increased leakage into the tissues (therefore poorly excreted)
Protein bound drugs are too large to pass through the vessel walls therefore, they cannot pass into the tissues to illicit a drug response only unbound drugs are “free” to attach to the receptor sites
33
excretion in geriatrics
LOOK FOR HIGH SERUM CREATINE (LOW KIDNEY FUNC
LOOK FOR ENZYMES IN LIVER (AST AND ALT) HIGH LEVELS INDICATE LIVER IS IN POOR FUNCTION.
