0.15mg
The dosage of epinephrine in an adult EpiPen is _____________.
0.30mg
When assisting with an auto-injector, how long should you hold the pen against the thigh?

Because the stinger of the honeybee is barbed and remains in the wound, it can continue to inject venom for up to _______________.
20 minutes.
Toxin
A poison or harmful substance
In dealing with allergy-related emergencies, you must be aware of the possibility of acute _______________ and cardiovascular collapse.
Airway obstruction
Substances that cause an allergic reaction
Allergens
Allergic Reaction
An exaggerated immune response to any substance
A reaction involving the entire body is called _________________.
Anaphylaxis
An extreme, life-threatening systemic allergic reaction that may include shock and respiratory failure
Anaphylaxis
After assisting with an EpiPen
Apply high-flow oxygen, take vital signs and place the used EpiPen in a biohazard container.
As you begin to asses a patient suspected of anaphylactic shock, which of these steps would be done first?
Assist with an EpiPen
Epinephrine inhibits the allergic reaction by constricting the __________ ___________.
Blood vessels
Wheezing occurs because excessive fluid and mucus are secreted into the _____________ _____________.
Bronchial passages
Speed is essential because in severe cases of anaphylaxis, ______________ can occur rapidly,
Death
The act of injecting venom.
Envenomation
A substance produced by the body (aka adrenaline) and a drug produced by pharmaceutical companies that increases pulse rate and blood pressure.
Epinephrine
T/F: For a patient appearing to have an allergic reaction, give 100% oxygen via nasal cannula
False
T/F: Wheezing is a high-pithed breath sound, usually resulting from blockage of the airway, and it heard on expiration.
False
Wheezing occurs because excessive _______________ and mucus are secreted into the bronchial passages.
Fluid
Allergens may include
Food, animal bites and semen
Stridor
Harsh, high-pitched inspiratory sound, usually resulting from upper airway obstruction
Wheezing
High-pitched, whistling breath sound usually resulting from blockage of the airway and typically heard on expiration
You have been called to a park where a local church is holding a potluck dinner. As you exit your ambulance, a woman approaches you holding her 7 y/o son who is wheezing and having difficulty breathing. She informs you that he had inadvertently eaten a brownie with nuts and he is allergic to nuts. Why is the patient wheezing?
His bronchioles are constricting
Substances released by the immune system that are responsible for many of the symptoms of anaphylaxis, such as vasodilation
Histamines
The presence of ________________ or respiratory distress indicates that the patient is having a severe enough allergic reaction to lead to death.
Hypoperfusion
Your ability to recognize and manage the many signs and symptoms of allergic reactions may be the only thing standing between a patient and _______________ ______________.
Imminent death
The ___________ system includes all of the structures and processes designed to mount a defense against foreign substances and disease-causing agents.
Immune
The body's response to substances perceived by the body as foreign.
Immune Response
The study of the body's immune system.
Immunology
Chemical substances that contribute to anaphylaxis
Leukotrienes
What does the "M" stand for in SAMPLE?
Medications- what medications is the patient currently taking?
Anaphylaxis is not always life threatening, but it typically involves:
Multiple organ systems
Urtucarua
Multiple raised areas on the skin that itch and burn
What does the "P" stand for in SAMPLE?
Past pertinent history
Epinephrine, whether made by the body or by a drug manufacturer, works rapidly to:
Raise the pulse rate and blood pressure, inhibit an allergic reaction and relieve bronchospasm
Wheal
Raised, swollen area on the skin resulting from an insect bite or allergic reaction
After removing the auto-injector from the child's thigh, you should:
Record the time, the dose and reassess his vital signs
When using the Twinject auto-injector:
Remove the safety cap, wipe the thigh with antiseptic and push the autoinjector firmly against the thigh for about 10 seconds.
Your assessment of the patient experiencing an allergic reaction should include evaluations of the:
Respiratory system, circulatory system and the skin
Eating certain foods, such as shellfish or nuts, may result in a relatively __________ reaction that still can be quite severe.
Slow
You should not use tweezers or forceps to removed an embedded stinger because:
Squeezing may cause the stinger to inject more venom into the wound
A harsh, high-pitched respiratory sounds, generally heard during inspiration, that is caused by partial blockage or narrowing of the upper airway.
Stridor
Leukotrienes
Substance made by body; released in anaphylaxis
Allergen
Substance that causes an allergic reaction
Signs and Symptoms of insect stings or bites include:
Swelling, wheals and localized heat
Prolonged respiratory difficulty can cause _____________, shock and even death
Tachycardia
Steps for assisting a patient with administration of an EpiPen include:
Taking body substance isolation precautions
A poison or harmful substance
Toxin
T/F: Allergic reations can occur in response to almost any substance.
True
T/F: An allergic reaction occurs when the body has an immune response to a substance
True
You have been called to a park where a local church is holding a potluck dinner. As you exit your ambulance, a woman approaches you holding her 7 y/o son who is wheezing and having difficulty breathing. She informs you that he had inadvertently eaten a brownie with nuts and he is allergic to nuts. You lift the child's shirt and find small, raised areas that he is trying to scratch. They are likely to be:
Uritcaria
Small areas of generalized itching or burning that appear as multiple, small, raised areas on the skin are called ____________.
Urticaria
Small spots of generalized itching and/or burning that appear as multiple raised areas on the skin.
Urticaria
A raised, swollen, well-defined area on the skin resulting from an insect bite or allergic reaction.
Wheal
Questions to ask when obtaining a history from a patient appearing to have an allergic reaction include:
Whether the patient has a history of allergies, what the patient was exposed to and how the patient was exposed.
The stinger of the honeybee is ___________, so the beed cannot withdraw it.
barbed
