NBDHE NBDHE Management of Special Needs Patients 2 — Questions and Answers
Question 1: A patient with Down syndrome presents for a routine cleaning. Which cardiac condition is most commonly associated with Down syndrome that requires antibiotic prophylaxis consideration?
- Mitral valve prolapse
- Atrioventricular septal defect (Correct answer)
- Pulmonary stenosis
- Tricuspid regurgitation
Correct answer: Atrioventricular septal defect
Atrioventricular septal defect (AVSD) is the most common congenital heart defect in patients with Down syndrome, occurring in approximately 40% of cases.
Question 2: When treating a patient with cerebral palsy, which positioning modification is most important during dental treatment?
- Placing the patient in full supine position
- Keeping the patient in a semi-upright position to reduce involuntary movements (Correct answer)
- Tilting the chair fully back to relax muscles
- Using a rubber dam only for isolation
Correct answer: Keeping the patient in a semi-upright position to reduce involuntary movements
A semi-upright position helps minimize involuntary movements and reduces the risk of aspiration in patients with cerebral palsy.
Question 3: A patient with autism spectrum disorder (ASD) is scheduled for a dental appointment. Which desensitization technique is most effective for reducing anxiety?
- Administering nitrous oxide immediately
- Using a tell-show-do approach with repeated pre-visit exposures (Correct answer)
- Scheduling longer single appointments to complete all treatment
- Providing written instructions only
Correct answer: Using a tell-show-do approach with repeated pre-visit exposures
Tell-show-do combined with repeated pre-visit exposures (desensitization visits) is the most effective behavioral approach for patients with ASD.
Question 4: Which of the following blood disorders requires the dental hygienist to obtain a current INR before performing scaling procedures?
- Sickle cell anemia
- Hemophilia A
- Warfarin anticoagulation therapy (Correct answer)
- Iron deficiency anemia
Correct answer: Warfarin anticoagulation therapy
Patients on warfarin therapy require a current INR (ideally below 3.5) before invasive dental procedures to assess bleeding risk.
Question 5: A patient with multiple sclerosis reports xerostomia as a side effect of their medication. Which oral health complication is of primary concern?
- Increased risk of periodontal disease only
- Elevated caries risk due to reduced salivary buffering capacity (Correct answer)
- Increased calculus formation
- Reduced gingival inflammation
Correct answer: Elevated caries risk due to reduced salivary buffering capacity
Xerostomia reduces salivary buffering and antimicrobial properties, significantly increasing the risk of dental caries.
Question 6: When providing dental hygiene care to a patient who uses a power wheelchair, what is the most important consideration?
- Always transferring the patient to the dental chair
- Assessing whether in-chair treatment is feasible before attempting transfer (Correct answer)
- Requiring a signed transfer consent form
- Using only hand instruments to avoid noise
Correct answer: Assessing whether in-chair treatment is feasible before attempting transfer
The dental hygienist must assess whether the patient can safely be treated in their wheelchair or if a safe transfer to the dental chair is feasible.
Question 7: A patient with type 1 diabetes presents with generalized gingival inflammation. What is the bidirectional relationship between diabetes and periodontal disease?
- Periodontal disease increases insulin sensitivity
- Poorly controlled diabetes increases susceptibility to periodontal disease, and severe periodontitis can worsen glycemic control (Correct answer)
- Periodontal disease only affects type 2 diabetics
- Gingivitis has no effect on blood glucose levels
Correct answer: Poorly controlled diabetes increases susceptibility to periodontal disease, and severe periodontitis can worsen glycemic control
The bidirectional relationship means hyperglycemia impairs immune response worsening periodontitis, while periodontal infection can elevate systemic inflammatory mediators affecting glycemic control.
