MOA of Bronchodilators
increasing the levels of the energy producing substance cAMP, cAMP causes the constricted airways of the lung to dilate, Relaxes the muscle of the respiratory tract, allowing greater airflow into and out of the lungs.
How do you get giardiasis?
contact with contaminated objects or
by drinking contaminated water
factors that influence adverse reactions of Local Anesthetics
**mentioned in test 2 review
Factors that influence toxicity aredrug's inherent toxicity and vasodilating effect
route of administration: IV has highest systemic affect, even topical can have systemic effect
rate of injection: rapid injection increasee systemic blood level
vascularity: inflamed or infected tissue = higher blood levels
pt weight: larger pts tolerate larger doses. Muscle is more vascular than fat, accounting for why pts of similar weight may have diff effects
metabolic rate and excretion: amides accumulate with liver disease. Both amides and esters may accumulate with renal disease.
which opioids do you use for mild to moderate pain?
Acetominophen (tylenol)
Not an NSAID. A COX 3 inhibitor. Hepatotoxic. No significant anti inflammatory properties.
The mechanism by which losartan (Cozaar) lowers blood presure is by:
Blocking angiotensin at its receptors
What are Barbiturates
Medicines that act on the CNS and cause drowsiness and can control seizures
Increases the available amount of gamma-aminobutyric GABA in the CNS
GABA has a relaxing, anti-anxiety and anticonvulsive
Effect the amount of CNS sedatoin depends on dose 
MOA selective serotonin reuptake inhibitors (SSRI's)
block the re-uptake of one neurotransmitter associated with mood: seratonin
SSRIs only work after they have achieved stady state
Side effects include GI upset, anorexia, and impotence 
how is lice transmitted?
by close body contact and shared item
autonomic nervous system
the part of the nervous system that controls involuntary actions
Hypertonic fluid is used to
to increase vascular volume and dehydrate the cells, causing them to shrink.
what spectrum is each of the penicillin groups?
natural - narrow spectrum
aminopenicillin - broad spectrum
penicillinase resistant - narrow
antipseudomonal - extended spectrum
what are examples of schedule 2?
opioid analgesics (morphine, codeine, meperidine), cocaine, amphetamines
This agent is one of the drugs used to treat generalized anxiety but does not cause sedation, CNS depression, or have potential for abuse like benzodiazepines:
Buspirone (Buspar)
Maalox/aluminum (mag) hydroxide ed
do not take within 1-2 hours of another med.
Side Effects - Extrapyramidal Symptoms (EPS)
Abnormal movement disorders due to imbalances in the neurotransmitters dopamine and acetylcholine.
Higher incidence of EPS is noted with traditional high potency antipsychotic 
Infusing antibiotics too rapidly will cause
Pain, a complication of IV therapy.
when are routine orders usually started?
within 2 hrs of being ordered
The best response for thrombolytic therapy will occur when it is:
Started within 4-6 hours after onset of symptoms
what are the 2 major groups of fungus infections?
systemic mycoses
superficial mycoses
Why would we use epinephrine with some local anesthetics 
Epinephrine is a vasconstrictor  
The action of benzodiazepines involve the interaction of these agents with
GABA receptor sites in the brain to cause inhibition of neuronal excitation
what is the route of infection for ancylostoma duodenale?
larvae penetrate through skin (usually bottom of feet)
they attach to the walls of the small intestine
Regional Anesthesia      
Anesthesia Cocaine was one of the first anesthetics to be discovered. These drugs prevent the generation and the conduction of the nerve impulse. Capable of causing CNS stimulation (restlessness, tremors, and clonic convulsions) followed by CNS depression, resp. depression, and death.
Direct Observation Therapy (DOT) for TB
used to ensure that a person with TB tkes all of the medications needed to cure their infection, provides support to individuals who are at risk for noncompliance to med regimine or have previously failed to adhere to med regimins, DOT worker delivers meds to participants 6 days a week. DOT also educates participants about the effects of their meds and the benefits of complying with their treatment regimens.
Viruses are difficult to treat for 2 reasons:
1. few drugs are selective enough to prevent viral replication without injuring the host
2. clinical sxs appear late in course of disease
dose of local anesthetic per 1.8 ml
2% = 36 mg
3% = 54 mg
4% = 72 mg
0.5% = 9 mg
/ 118
