All of the following are essential items for the dental office emergency kit except one. Which one is the exception?
Atropine
If a patient is experiencing a severe asthma attack what is the first drug of choice?

If a patient is experiencing a sever asthma attack and the first drug of choice doesn’t work, what is the next drug of choice?
Epinephrine
Epinephrine should not be given to which type of patient because it can exacerbate their condition?
Ischemic heart disease and severe hypertension
True or False
Does nitroglycerin have a rapid onset?
True
What is the more effective form of nitroglycerine?
Spray, tablet life is reduced when exposed to light (can be as a little as 12 weeks)
How is nitroglycerine administered?
Tablet (sublingually) 0.2 - 0.6 mg
Spray (one spray translingually or sublingually)
Two additional doses can be administered at 5 minute intervals
What is recommended for management of allergic reactions?
Histamine blocker
10 mg chlorpheniramine
20-50 mg diphenhydramine
What is the pediatric dose of diphenhydramine?
1 mg per kilogram of body weight and should not exceed the adult dose
True or False
Albuterol has a quick onset, with a peak effect of 30-60 minutes and a long duration of action 4 to 6 hours
True
What is the adult dose of albuterol?
2 puffs, with the maximum of 12 puffs per day
True or False
If the initial dose of albuterol is ineffective, the use of a spacing device is recommended as it allows for more effective distribution of the drug in the lungs.
True
True or False
If aspirin is administered early enough during MI, the drug will help prevent the progression from cardiac ischemia to cardiac injury to cardiac tissue death.
True
What is the minimum effective dose of aspirin to give to a patient with pain suggestive of MI?
At least 162 mg or two baby aspirins
True or False
Oral carbohydrates are source for conscious patients suffering from hypoglycemia.
True
Glucose paste and tablets are recommended as they do not require refrigeration and they have long shelf lives.
True
Juice or non-diet soda can be used if tablets and paste are unavailable.
True
What drug is used for management of prolonged or recurrent seizures or hyperventilation?
Injectable benzodiazepine
Lorazepam is considered the benzodiazepine of choice for use of seizures because it can be administered intramuscularly.
The adult dose of Lorazepam is?
4 mg intramuscularly (IM)
True or False
Glucagon administered IM is the drug of choice for the unconscious hypoglycemic patient.
True
What is the recommended glucagon dosage for adults?

0.5 mg for patient weighing less than 20 kg
Corticosteroids have a fast or slow onset of action?
Slow
What is the corticosteroid of choice for the emergency kit in a dental office?
Hydrocortisone (100 mg - injectable)
What is a corticosteroid used for?
Prevention of a recurrence of an anaphylactic reaction and management of adrenal crisis
Reduction of histamine release
