-41-yo woman, pregnant; prev rheumatic fever with heart murmur (no valvular
abnormality); allergy to penicillin. Positive history of infective endocarditis. Does she
need to pre med?
- yes
- no - -yes
- REVIEW HEALTH HISTORY - on my exam, this patient had a previous history of
infective endocarditis. Pre-med IS indicated
- many of the OSCE quizlets say no....
-Pre-med options for pregnant woman w/hx of infective endocarditis and penicillin
allergy
- amoxicillin
- cephalexin
- clarithromycin
- ciproflaxacin - -*clarithromycin*
,I may not be correct, the correct option may be cephalexin. however I chose
clarithromycin due to penicillin allergy, cross reaction with cephalosporins, and since
clindamycin/erythromycin/azthromycin were not options. Ciproflaxacin is
contraindicated in pregnancy. article for reference

-What procedure can a dentist perform without consulting MD if a patient is currently
taking bisphosphonates?
- endo therapy
- prophy and scaling
- extraction
- occlusal restoration - -*occlusal restoration*
although the main HELL NO is extraction, completing endo therapy increases risk if the
apex is compromised/damaged during therapy. I teetered on prophy and scaling, but
since it did not specify supragingival, decided that the risk of scaling can negatively
affect the periosteum of a bisphosphanate patient. ADA recommendations:

-Pregnant person afraid of needles - stress management by putting patient in what
position when in your chair (BEFORE they even get to the point of passing out)?
- supply oxygen
- place in Trendelenburg
- make patient sit up straight
- tell them to suck it up buttercup - -place her in Trendelburg position.
- supine hypotension in 3rd trimester usually occurs (bc compression Inf vena cava) =>
must prevent this in dental chair bc it can cause patient to pass out.
- Best preventative treatment for supine hypotension is to turn the patient, preferably to
the left side, to displace the uterus away from the inferior vena cava. The patient can
also be placed in a sitting position with the knees flexed.
-6 months pregnant had bleeding gums and mobile teeth, how should they be treated?
,- immediate extractions
- do not treat until baby is born
- conservative debridement
- immediate endo - -conservative debridement
.- pregnancy gingivitis: important to do ScRP (and stress good oral hygiene) to prevent
plaque growth. The plaque can enter blood stream and stimulate patient's immune
system to produce prostaglandins, which can trigger uterine contraction leading to early
labor, premature birth, and a small baby.
-Pregnant lady with a diastema in between #8 and #9 with deep probing depth and
class 1 mobility on 8 and 9. What is the reason for diastema?
- chronic periodontitis
- distal drift
- normal during pregnancy - -chronic perio
- increased incidence of periodontal disease during pregnancy => must emphasize good
oral hygiene, and remove all their plaque so it doesn't lead to premature birth / low
birth weight
-Permanent staining as a result of tetracyline; did this happen?
- During development (as fetus)
- 0-5yrs
- 5-10 yrs

, -A patient has an allergic reaction to a barbiturate, how do you treat?
- epinephrine
- diphenhydramine
- send to ER - -benadryl (diphenhydramine)
- And discontinuation of the drug. Obviously if there are concerns with airway,
treatment may differ... but this was not indicated in the question stem. However, I did
not have answer choices that reflected this scenario nor was it addressed in the question
stem
-A patient is on a steroidal medication. What information do you need to obtain before
treating them?
- dose and pharmacy that filled the RX
- duration of prescription
- both dose and duration - -*dose and duration*
- "The rule of twos": Ask whether the patient is currently on steroids or has been on
corticosteroids for 2 weeks or longer within the past 2 years. You must go back 2 years in
the history because it can take 2 weeks to 2 years for the adrenal glands to bounce back
to normal function.

disease is a significant oral health issue, but this was not an answer for those who have
had this question. Consider cardiac status and posibility of pre-medication
- atrioventricular septal defect, patent ductus arteriosus, Tetralogy of Fallot
