Term | Definition |
Drug Therapy for pediatric patients, Medicines effect peds differently, how? | absorption slower gastric emptying
distribution 75% body is water, require higher dose of water soluble drug
metabolism develop at different stages
excretion kidneys are not completely mature till 1 yr |
Determining pediactric dosage | Body Surface Area (physicians use) and weight/kg |
Where do you give an IM injection to a kid under 3? | vastus laterus |
Where do you give an IM injection to a kid over 3? | dorso gluteal |
How do you administer ear drops to a child? | down and back/out |
If child ingests a poisionous medication what can you give them? | syrup of ipecac |
If child ingests a poision, who do you call? | poision control |
Polypharmacy | taking numerous medications on daily basis |
Drug therapy in the Elderly; medications effect elderly differently how? | blood flow decreases to the GI tract, decrease in GI secretions-absorption decreases, fatty tissues increase-decreases activity or prolonged activity in many drugs, decreased binding sites, decreases blood flow to liver leading to toxicity |
IM injection preferred site for the elderly? | ventrogluteal |
Asepsis | free of pathogenic microorganisms |
medical aspesis | "clean technique" inhibits growth |
surgical aspesis | "sterile technique" destroys/abscent from microorganisms |
Principles of sterile technique | sterile objects remain sterile when touched only by sterile, only sterile can be place on sterile field, sterile objects our of sight/held below waist become contaminated, if field becomes wet contaminated, edges (1 in) contaminated |
Sympathetic (Adrenergic) System | Fight or Flight, increases processes when faced with stress, supresses those body functions not vital during stressful situation |
Examples of body reactions for Sympathetic | pupils dilate, heart rate increase, blood vessels dilate |
Receptors in the Sympathetic System | alpha 1
beta 1
beta 2 |
Alpha1 | found in smooth muscles of the peripheral blood vessels, GI GU tracts, when stimulated cause constriction, BP increases, used commonly in hypotension meds |
Beta1 | primarily found in the heart, when stimulated increases heart rate, force, and contractions |
Beta2 | primarily found in bronchial smooth muscles (lungs) when stimulated bronchodilation meaning OPENS UP airways |
Parasympathetic (Cholinergic) | opposite of sympathetic, directed in conversing energy; increased acid secretions, salvation, decrease heart rate and BP, pupil constriction, promotes sweating, increased elimination |
4 classes/agentsof drugs that effect the Autonomic Nervous System | 1.Sympathetic or Adrenergic Agents
2.Sypatholytics or Adrenegic Blockers
3.Parasympathominetics or Cholinergics
4.Parasympatholytic or Anticholinergic |
Adrenergic Agents | mimic the sympathetic nervous system |
Adrenergic Blockers | stop/block adrenergic system, decreases/constrict |
Cholinergics | mimics parasympathetic, increases secretions conserves energy increases SLUD |
Anticholinergic | antiSLUD, decreases or stops SLUD |
SLUD stands for | S-SALIVATION
L-LACRIMATION
U-URINATION
D-DEFICATION |
