Questions and CORRECT Answers
What is almost always present in medical emergencies involving loss of consciousness -
CORRECT ANSWER some degree of airway obstruction
Which two steps of BLS are designated to eliminate airway obstruction problems - CORRECT
ANSWER A- airway
B- breathing
Predisposing factors of respiratory distress - CORRECT ANSWER - hyperventilation
- vasodepressor syncope
- asthma
- hypoglycemia
- overdose reaction
- acute MI
- anaphylaxis
- CVA
- epilepsy
- hyperglycemic reaction
Anoxia - CORRECT ANSWER absence of oxygen
Apnea - CORRECT ANSWER absence of respiratory movement
Dyspnea - CORRECT ANSWER difficulty in breathing "air hunger"
Hyperventilation - CORRECT ANSWER - ventilation that exceeds metabolic demands
,- more than 28 respirations
- no longer have a maintenance of O2 and CO2 balance
- caused by increase frequency of respirations and depth of respirations
- commonly in people age 15-40
- occurs as result of extreme acute anxiety
Hypoxia - CORRECT ANSWER deficiency of O2 in inspired air
Orthopnea - CORRECT ANSWER inability to breathe except in the upright position
Tachypnea - CORRECT ANSWER greater than normal respiratory rate
Underlying medical disorders than can cause respiratory distress - CORRECT ANSWER -
acute MI
- anaphylaxis
- CVA
- hyperglycemia
- hypoglycemia
- acute exacerbation of above conditions
Chronic respiratory problems - CORRECT ANSWER asthma and heart failure
Undue stress effects on respiratory disease - CORRECT ANSWER physiologic or
psychologic stress can exacerbate respiratory disorders and each other
Which conditions are almost exclusively manifestations of psychologic stress and the most
frequent emergency situations in dentistry - CORRECT ANSWER hyperventilation and
vasodepressor syncope
, Children with asthma in stressful situations - CORRECT ANSWER may exhibit acute
episodes of bronco spasms
Prevention of respiratory distress - CORRECT ANSWER - stress reduction protocol
- adequate pretreatment- medical and dental evaluations
Exceptions in stress reduction protocol - CORRECT ANSWER diabetes- plan appointment
for after lunch
parkinsons- plan appointment for when medication is most effective
Clinical manifestations of respiratory disease - CORRECT ANSWER - varies according to
degree of breathing difficulty present
- patient usually remains conscious
- acute anxiety/ panic
- asthma- wheezing sounds
- heart failure- wet cough and other sounds associated with pulmonary congestion
Pathophysiology of asthma - CORRECT ANSWER - bronchi become highly reactive, related
to restricted exchange of O2 and carbon dioxide in the lungs
- extreme sensitivity of airways
- abnormal generation and clearance of secretions
- abnormally sensitive cough reflex
Pathophysiology of heart failure - CORRECT ANSWER related to an engorgement of the
pulmonary veins with fluid exuding into alveolar sacs
Pathophysiology of hyperventilation - CORRECT ANSWER primary site is in the brain, rapid
breathing results in elimination of an excessive amount of carbon dioxide
