Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],

            agm, but no reports or case studies have 
described an allergic response to the latex component 
of the cartridge containing a dental local anesthetic
4) Topical Anesthetic Allergy
The most commonly used topical anesthetics in dentistry are 
esters, such as benzocaine and tetracaine
Benzocaine: 
poorly absorbed systemically, allergic responses that develop in 
response to its use are normally limited to the site of application
When other topical formulations, ester or amide, that are 
absorbed systemically are applied to mucous membranes, 
allergic responses may be localized or systemic
Many contain preservatives such as methylparaben, 
ethylparaben, or propylparaben
Prevention ?
Medical History Questionnaire
Most medical history questionnaires contain several questions related to allergy : 
Are you allergic to (e.g., have itching, rash, swelling of hands, feet, or eyes) or made 
sick by penicillin, aspirin, codeine, or any other medications?
Have you ever had asthma, hay fever, sinus trouble, or allergies or hives?
Dialogue History
The following questions are included in the dialogue history  between the dentist and a patient with an alleged allergy to LA : 
1. Describe exactly what happened. (Describe your “allergic” reaction)
2. What treatment was given?
3. What position were you in during injection of the local anesthetic?
4. What was the time sequence of events?
5. Were the services of emergency medical personnel necessary?
6. What drug was used?
7. What volume of the drug was administered?
8. Did the local anesthetic solution contain a vasoconstrictor?
9.  Were you taking any other drugs 
or medications at the time of the 
incident?
10.  Can you provide the name, 
address, and telephone number of 
the dentist or physician who was 
treating you when the incident 
occurred?
1. This is probably the most important question because it allows the patient to describe the actual sequence of events
Allergic reactions vs  anxiety-induced reaction?
Allergic reactions 
anxiety-induced reaction
skin (itching, hives, rash, edema)
gastrointestinal system (cramping, 
diarrhea, nausea, vomiting)
exocrine glands (runny nose, watery 
eyes)
respiratory system (wheezing, laryngeal 
edema)
CVS (angioedema, vasodilation, 
hypotension)
in which they experienced : 
palpitations
severe headache
sweating
mild shaking (tremor)
Cause ?  of psychogenic origin or are related to the
administration of overly large doses of a vasoconstrictor (e.g., 
epinephrine)
Example : Hyperventilation 
•
patients lose control over their breathing (inhaling and exhaling 
rapidly and deeply) 
•
is accompanied by dizziness, lightheadedness, and peripheral 
paresthesia (fingers, toes, and lips)
2. The drugs used in the management of allergic reactions
include three categories:
1)
vasoconstrictors 
2) histamine blockers 
3) corticosteroids 
Aromatic ammonia is frequently used in the treatment 
of syncopal episodes
Anticonvulsants, such as diazepam or midazolam, are 
administ
