complete solution
What do veta blockers do:
Reduce the heart rate and blood pressure
Angina pectoris is due to
Lack of blood supply ( the heart is injure)
Name the 2 systems that compromise the anatomic nervous system
Sympathetic (Adrenergic the accelerator ) and parasympathetic (cholinergic the brakes )
insufficient blood flow through the coronary arteries can result in
Angina
Beta one controls the
Heart
Follow the pathway of the blood flow through the heart
Superior and inferior vena cava to the right atrium Past the tricuspid Valve and into the
right Ventricle. Past the pulmonic valve to the Pulmonary Artery. To the lungs where it
picks up oxygen. Left atrium, left ventricle, aorta to the rest of the body
Conduction of the nerve impulse is call?
Depolarization
The secret of nerve conduction and the action of anesthetic agents is
Sodium ions + and chloride ions -
Where does anesthetic works in the central nervous system?
In the center of emotions, the wakefulness system, Brain stem and hypothalamus
Sympathetic
adrenergic, the accelerator in the car, fight or flight
elimination of drugs happens in the
Kidneys
Parasympathetic
cholinergic, the brakes (couch potato, vegetation state
Increase in saliva is due to stimulation of the
Parasympathetic system
The main organ that process the anesthetic drugs and changes the chemical
structure of the drug is
The liver
Nerve conduct impulses by
Depolarization of the nerve membrane
Anesthetic agents act by
Interfering with the depolarization of the membrane
An increase of heart rate and blood Pressure are due to the stimulation of the
Sympathetic system
Normally a blood cell is polorized this means
There are more positive ions on the outside of the cell and more negative ions on the
inside
Metabolism of drugs occur where?
The liver
, The organ responsible for eliminating drugs ?
Kidneys also lungs, sweat, saliva and feces
Anesthetic agents act by
Interfering with the depolarization of the membrane
Most rapid method of administering and on set of action
Intravenous administration
Sevoflurane (Ultane)
used for pediatric anesthesia because it has a rapid induction and recovery, non irritant
to airway
How long should oxygen be administer after NO2 is turn off
5 to 10 minutes
ethyl chloride
Numbs by quickly cooling and freezing the surface to be injected
topical anesthesia for venipuncture
Emla (lidocaine and prilocaine ) need to cover area with tegaderm patch for at least 60
minutes
What are the most common benzodiazepines
Diazepam (Valium ) medazolam( versed)
Reversible drug for diazepam(Valium) and versed (medazolam)
Flumazenil 2.20 mg/IV (Romazicon)
What is a disadvantage of using diazepam
Insoluble in water, vein irritation, Half-life 20-40 hrs
Reversible drug for midazolam ( versed)
Flumazenil
Morphine Sulfate reversible drug
Narcan
Best narcotic medicine for asthmatic patients and with a history of nausea and
vomiting
Fentanyl (more potent than morphine) about 100times
A drugs that reduces secretions
Atropine (rubinul) inverses heart rate
A drug that reduces swelling
Decadron (dexametosome) is a steroid
Shutting off nitrous oxide and allowing the patient to breath room air can result in
Diffusion hypoxia
Nitrous Oxide
Should always be used in combination with oxygen, produces euphoria and promotes
relaxation, is non flammable liquid, is stored in blue tanks.
What is the function of narcotics( morphine, codeine, Demerol, fentanyl)
Pain killers/ primary use as analgesic
What is the most rapid and effective method of drug administration
Intravenously IV
Site of action of propofol and brevital
Wakefulness system
Opioids drug reversal for fentanyl, morphine
Narcan
