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

(on 2024 exam)

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

(on 2024 exam)

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 https://www.parents.com/pregnancy/my-body/is-it-safe/antibiotics-and-pregnancy/

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

(on 2024 exam)

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

(on 2024 exam)

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 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?

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

(on 2024 exam)

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.

- atrioventricular septal defect, patent ductus arteriosus, Tetralogy of Fallot

A patient has recently had a stroke. What is your first concern?

- when was their last cleaning

- are they on anticoagulants

- current blood pressure

Are they on anticoagulants

- Stroke patients could be on blood thinners, such as aspirin, dipyradamole (Persan- tine), clopidogrol (Plavix), or Coumadin, postrecovery. Prior to major surgery, always consult with the patient's physician to determine whether and when the blood thinners can be stopped and subsequently restarted.- . Following a CVA that required significant hospitalization, routine dental treatment must be delayed by 6 months.- Routine dental treatment should be delayed by 3 months if the post-CVA recovery was uneventful and the patient was admitted overnight just for observation.- Avoid epinephrine containing LAs during the first 6 months of dental treatment. Subsequent use of epinephrine depends on the patient's prognosis. Epinephrine containing LAs can be used starting 1 year after the stroke, when the patient demonstrates progressive improvement of the CVA and absence of TIAs.

What is the main symptom that differentiates anaphylaxis from syncope?

- bronchoconstriction

- clammy skin and pallor

Palpitation, tachycardia, sub- sternal tightness, coughing, wheezing, and dyspnea. BP drops rapidly and loss of consciousness or cardiac arrest can occur in severe cases.- syncope: fright and flight response. Anxiety, tachycardia, perspiration, light-headedness, and blurred vision are commonly experienced.
