what does it mean to be addicted?
to be physically dependent on a drug
what is a Rx Body?
Also known as the “signature”, includes the type of medication, dosage, and quantity of medication prescribed (the instructions, in other words)
routes of administration: oral route
pills, tablets, capsules, & liquids
the most common route, but also the slowest route
routes of administration: Inhalation route
Inhaling a gaseous substance and allowing it to be absorbed through the lungs (O2 is the most commonly used drug in a med. emergency)
routes of administration: sublingual route
medication is placed under the patient’s tongue & allowed to dissolve & be absorbed through the mucosal tissue
injection (parenteral) routes: Subcutaneous (SC):
The drug is injected under the skin, into fat
injection (parenteral) route: Intramuscular (IM)
the drug is injected directly into a muscle
injection (parenteral) route: Intravenous (IV)
the drug is injected directly into a blood vessel
injection (parenteral) route: Intradermal (ID)
the drug is injected between the layers of skin
what color is the emergency oxygen tank?
the tank’s color is green
what is the assistant’s role in a healthcare office?
the assistant’s role is to monitor the patient for signs of an impending medical emg
what are the signs of an impending medical emg.?
Eyes: Pupil dilation and vascularization
Gait: The way a patient walks
Speech: Slurred or strained?
Signs of anxiety
what is the first step if a patient has a medical emergency and/or goes unconscious?
the first step is to remove all items from the patient’s mouth and call 911 if they are unconscious
what is the second step if a patient has a medical emergency and/or goes unconscious?
the second step is the take and evaluate the patient’s vital signs, starting with pulse
if unconscious make sure the patient’s airway is open by tilting their head back & chin up
what is the third step if a patient has a medical emergency and/or goes unconscious?
the third step is to place your ear over the patient’s mouth to listen and feel for breaths while also watching their chest for signs of respiration (chest rise and fall)
what is the fourth step if a patient has a medical emergency and/or goes unconscious?
the fourth step is to perform CPR
how should CPR begin/the first step?
cpr should begin with 30 chest compressions, which should be performed at a rate of 100 compressions per minute.
Compressions should be performed on the patient’s lower 1/3 of the sternum
what is the second step to CPR?
deliver 2 rescue breaths for 1.5 – 2 seconds per breath.
The goal is to see the chest rise in the victim, accomplished with “normal” breaths.
Do not deliver breaths that are too forceful or deep.
what is the compression-to-breath ratio?
the compression-to-breath ratio is 30 compressions to 2 breaths (30:2)
what should you use if the patient is not revived by performing CPR?
the automated external defibrillator (AED) will be used as the electrical jolt will reset the heart rhythm to a normal pattern
when are the electrodes of the AED placed?
the electrodes of the AED are placed only when the patient is not breathing, their heart has stopped beating and they are unconscious
cardiac arrest
this is when the patient is unresponsive, shows no signs of normal breathing, and does not have a pulse ; treatment is immediate CPR

what should hypoglycemic patients be asked?
hypoglycemic patients should be asked if they have eaten before treatment.

Arteriosclerosis
arteriosclerosis is the cause of the majority of cardiovascular emergencies
what does arteriosclerosis do?
arteriosclerosis causes the narrowing and hardening of the arteries, thus a decrease in oxygen-rich blood flowing to the heart
angina
angina is chest pain caused by a temporary decrease in blood flow to the heart
myocardial infaction (MI)
myocardial infarction is also known as a heart attack in which a part of the heart is not receiving enough blood and oxygen.
how is Arteriosclerosis treated?
Arteriosclerosis is treated with blood thinner medications
how is angina treated?
angina is treated by administering Nitroglycerin sublingually or in an oral spray
how are myocardial infarctions treated?
myocardial infarctions are treated by:
Administer Nitroglycerin & oxygen
Monitor vital signs
Be prepared to start CPR if respiratory & cardiac failure occur
