SECTION 1: MEDICAL & DENTAL ASSESSMENT (14 Questions)
Q1: A 58-year-old patient presents for dental hygiene treatment. Their blood pressure is
recorded as 168/104 mmHg on two separate occasions 15 minutes apart. The patient
reports they "forgot" to take their antihypertensive medication this morning. What is the
appropriate dental hygiene management?
A. Proceed with routine scaling and root planing with local anesthesia
B. Defer elective treatment and refer to physician for blood pressure evaluation
C. Administer nitrous oxide/oxygen sedation to reduce anxiety and blood pressure
D. Limit treatment to supragingival scaling only without local anesthesia
Correct Answer: B
Rationale:
● Why correct: According to the American Dental Association (ADA) and American
Heart Association (AHA) guidelines, a blood pressure reading of 168/104 mmHg
falls into Stage 2 hypertension (systolic ≥140 or diastolic ≥90). Elective dental
treatment should be deferred, and the patient should be referred to their
physician for blood pressure management. The risk of cardiovascular
, complications (stroke, myocardial infarction) during dental procedures is
significantly elevated with uncontrolled hypertension.
● Distractor analysis:
○ A is incorrect because: Performing invasive procedures with local
anesthesia (containing epinephrine) on a patient with Stage 2
hypertension increases the risk of hypertensive crisis, cardiac arrhythmias,
or cerebrovascular accidents.
○ C is incorrect because: Nitrous oxide/oxygen sedation does not lower
blood pressure and may actually cause sympathetic stimulation in some
patients. It is contraindicated as a method to "treat" hypertension.
○ D is incorrect because: While supragingival scaling is less invasive, any
elective treatment should be deferred until blood pressure is controlled.
The patient needs medical evaluation first.
● Clinical pearl: The dental hygiene appointment is an ideal opportunity for blood
pressure screening. Document all readings and follow the "180/110 rule"—defer
elective treatment if BP ≥180/110 mmHg, and refer immediately if ≥180/110
mmHg with symptoms.

Q2: A patient with Type 1 diabetes mellitus schedules a 9:00 AM dental hygiene
appointment. They state they normally take 15 units of NPH insulin at 7:00 AM and eat
breakfast at 7:30 AM. What is the most appropriate recommendation for this patient on
the day of their appointment?
A. Take insulin as usual and eat breakfast normally before the appointment
B. Skip breakfast and insulin to avoid hypoglycemia during the procedure
C. Take half the usual insulin dose and eat a light breakfast
D. Reschedule the appointment for later in the day when insulin peaks have passed
Correct Answer: A
Rationale:
● Why correct: The patient should maintain their normal routine of insulin
administration and meals. NPH insulin has an onset of 1-2 hours and peaks at
4-12 hours. A 9:00 AM appointment allows sufficient time after the 7:00 AM
, injection and 7:30 AM breakfast to monitor for hypoglycemic reactions. The
dental hygienist should ensure the patient has eaten and verify blood glucose
levels before beginning treatment.
● Distractor analysis:
○ B is incorrect because: Skipping insulin and breakfast places the patient at
risk for hyperglycemia, diabetic ketoacidosis (DKA), and hypoglycemia
during the stress of dental treatment. Never advise patients to skip
prescribed medications.
○ C is incorrect because: Altering insulin doses without physician
consultation can lead to dangerous blood glucose fluctuations. Dental
hygienists should not advise patients to modify insulin regimens.
○ D is incorrect because: While afternoon appointments may be preferable
for some diabetic patients on insulin, it is unnecessary to reschedule if the
patient has followed their normal routine and blood glucose is within
acceptable range (80-180 mg/dL).
● Clinical pearl: For morning appointments, diabetic patients should maintain their
normal insulin and meal schedule. Always confirm they have eaten, check blood
glucose if indicated, and keep a glucose source (orange juice, glucose tablets)
readily available.

Q3: Which of the following medical conditions requires antibiotic prophylaxis prior to
dental hygiene procedures that may cause gingival bleeding, according to current
American Heart Association (AHA) guidelines?
A. Mitral valve prolapse without regurgitation
B. Previous coronary artery bypass graft surgery
C. Prosthetic cardiac valve placed 6 months ago
D. Cardiac pacemaker implantation
Correct Answer: C
Rationale:
● Why correct: Prosthetic cardiac valves (mechanical or bioprosthetic) are
considered high-risk cardiac conditions for infective endocarditis. Current AHA
guidelines recommend antibiotic prophylaxis for dental procedures involving
, manipulation of gingival tissue, periapical region, or perforation of oral mucosa in
patients with: prosthetic cardiac valves, previous infective endocarditis, certain
congenital heart diseases, or cardiac transplant with valvulopathy.
● Distractor analysis:
○ A is incorrect because: Mitral valve prolapse without regurgitation is NOT
an indication for antibiotic prophylaxis. Only MVP with regurgitation
and/or thickened leaflets was previously considered, but current
guidelines have eliminated this recommendation.
○ B is incorrect because: Coronary artery bypass graft (CABG) surgery is
NOT an indication for antibiotic prophylaxis. The native vasculature is not
at risk for infective endocarditis from bacteremia.
○ D is incorrect because: Cardiac pacemakers and implanted defibrillators
are NOT indications for antibiotic prophylaxis. These are extracardiac
prosthetic devices, and the risk of device infection from dental procedures
is extremely low.
● Clinical pearl: When in doubt, consult the AHA guidelines (Circulation
2007;116:1736-1754, reaffirmed 2017). Document the specific cardiac condition
and consult with the patient's cardiologist if the indication for prophylaxis is
unclear.

Q4: A 45-year-old patient presents with a history of bisphosphonate therapy
(alendronate 70 mg weekly) for osteoporosis for the past 4 years. They require
periodontal scaling and root planing. What is the primary concern regarding dental
treatment for this patient?
A. Increased risk of postoperative bleeding
B. Risk of medication-related osteonecrosis of the jaw (MRONJ)
C. Enhanced effect of local anesthetics causing prolonged numbness
D. Contraindication to epinephrine in local anesthetics
Correct Answer: B
