Question 1 of 6
1. Question
A regulatory inspection at a private bank focuses on Management of Patients with Prosthetic Rehabilitation of the Skin in the context of conflicts of interest. The examiner notes that the bank’s specialized medical trust division, which manages funds for patients requiring complex facial and skin prosthetics, has utilized a single vendor for all silicone-based materials over the last 24 months. The trust’s lead administrator is the spouse of the vendor’s Chief Operating Officer. While this relationship was documented in the bank’s annual conflict-of-interest registry, the internal audit report indicates that no competitive bidding was conducted and the administrator remained the final signatory on all purchase orders. Which of the following should the internal auditor identify as the primary deficiency in the bank’s risk management framework?
Correct
Correct: In the context of internal auditing and professional ethics, the identification and disclosure of a conflict of interest is insufficient if it is not followed by active mitigation. The primary deficiency is that the bank allowed the conflicted individual to maintain decision-making authority (signatory power) without a recusal protocol or independent oversight, which creates a significant risk of biased procurement and financial loss to the trust.
Incorrect: Rotating staff periodically is a general preventive control but does not specifically address the governance failure of an existing, disclosed conflict. Restricting vendors to non-profits is an unnecessary business constraint that does not align with standard risk management practices. While automated background checks are a useful detection tool, they do not solve the problem of how to manage a conflict once it has already been disclosed and documented.
Takeaway: Internal auditors must ensure that disclosed conflicts of interest are managed through active mitigation strategies, such as recusal or independent oversight, rather than just being documented in a registry or disclosure form.

Question 2 of 6
2. Question
A whistleblower report received by an insurer alleges issues with Management of Patients with Prosthetic Rehabilitation of the Trunk during regulatory inspection. The allegation claims that the facility’s prosthetic protocols for mandibular dentures fail to identify the correct anatomical landmarks for primary load-bearing, leading to increased patient morbidity. In conducting a risk-based audit of the clinical guidelines for the past fiscal year, which anatomical area should the auditor confirm is designated as the primary stress-bearing site to ensure the stability of the mandibular prosthesis?
Correct
Correct: The buccal shelf is the primary stress-bearing area for the mandibular complete denture because it is composed of dense cortical bone and is oriented perpendicular to the vertical occlusal forces, providing superior resistance to resorption.
Incorrect: The crest of the residual ridge is considered a secondary stress-bearing area as it is primarily cancellous bone and more prone to resorption under load. The retromylohyoid fossa is a landmark used to determine the posterior-lingual extension of the denture for stability but does not support occlusal loads. The genial tubercles are sites for muscle attachment and typically require relief to prevent displacement of the denture and patient discomfort.
Takeaway: The buccal shelf is the primary stress-bearing area for mandibular complete dentures due to its cortical bone structure and resistance to occlusal forces.

Question 3 of 6
3. Question
Which practical consideration is most relevant when executing Management of Patients with Prosthetic Rehabilitation of the Mouth? A 72-year-old edentulous patient presents with significant alveolar ridge resorption in the mandible. During the final impression stage, the clinician aims to maximize the support for the mandibular complete denture. Which anatomical landmark should be prioritized for primary stress-bearing to ensure long-term stability and minimize further bone loss?
Correct
Correct: The buccal shelf is the primary stress-bearing area of the mandible. It is bounded medially by the crest of the ridge and laterally by the external oblique line. Because it is composed of dense cortical bone and its surface is relatively perpendicular to the vertical forces of mastication, it provides excellent support and resists resorption significantly better than the ridge crest.
Incorrect: The crest of the mandibular residual ridge is considered a secondary stress-bearing area because it consists of cancellous bone and is highly susceptible to resorption under pressure. The mylohyoid ridge is a site of muscle attachment and is often sharp; applying pressure here leads to mucosal irritation and denture displacement. The genial tubercles are located on the lingual aspect of the anterior mandible and are typically relief areas because the overlying mucosa is thin and the area is sensitive to pressure.
Takeaway: In the mandibular arch, the buccal shelf serves as the primary stress-bearing area due to its cortical bone structure and favorable orientation relative to occlusal loads.

Question 4 of 6
4. Question
What factors should be weighed when choosing between alternatives for Management of Patients with Prosthetic Rehabilitation of the Skull? In the clinical management of an edentulous patient with a large Aramany Class II maxillary defect, a clinician is evaluating whether to utilize a hollow-bulb (closed) definitive obturator or an open-bulb (obturator) design.
Correct
Correct: In maxillofacial prosthetics, the weight of the prosthesis is a critical factor for retention and stability, especially in large maxillary defects. A hollow-bulb (closed) obturator reduces the weight of the prosthesis, which prevents downward displacement due to gravity and improves the resonance of the patient’s voice. However, it requires a precise seal to prevent the internal cavity from becoming a reservoir for bacteria and fluids. The open-bulb design is easier to fabricate and clean but lacks the weight-reduction benefits and can collect food debris more easily.
Incorrect: Increasing the weight of a maxillary prosthesis (option b) is counterproductive as gravity works against retention in the maxilla. Engaging the nasal septum with resilient liners (option c) is generally avoided due to the sensitivity and fragility of the septal mucosa. The hollow-bulb design does not dictate the vertical dimension of occlusion (option d), which is determined by the maxillomandibular relationship and phonetic/functional requirements of the patient.
Takeaway: The selection of obturator design for large cranial defects must balance the biomechanical necessity of weight reduction for retention against the practical requirements of hygiene and speech quality.

Question 5 of 6
5. Question
A new business initiative at a credit union requires guidance on Management of Patients with Prosthetic Rehabilitation of the Intestines as part of record-keeping. The proposal raises questions about the clinical standards for edentulous patients with systemic malabsorption. During a 90-day quality assurance review of prosthetic treatment plans, which anatomical landmark is identified as the primary stress-bearing area for a mandibular complete denture in cases of advanced residual ridge resorption?
Correct
Correct: The buccal shelf is the primary stress-bearing area for the mandibular denture because it is composed of dense cortical bone and is oriented perpendicular to the direction of vertical occlusal loads, providing superior resistance to resorption compared to the ridge crest.
Incorrect: The retromolar pad is a critical landmark for determining the occlusal plane and providing a posterior seal but is not the primary support area. The mylohyoid ridge is a secondary support area and often requires relief due to thin mucosa. The genial tubercles are muscle attachment sites that may interfere with denture base extension in cases of extreme resorption but do not provide support.
Takeaway: The buccal shelf is the primary stress-bearing area in the edentulous mandible due to its cortical bone density and favorable biomechanical orientation.

Question 6 of 6
6. Question
Working as the risk manager for a listed company, you encounter a situation involving Management of Patients with Prosthetic Rehabilitation of the Limbs during business continuity. Upon examining a policy exception request, you discover th…at the clinical quality controls for the dental division do not specify the anatomical requirements for mandibular final impressions. To mitigate the risk of prosthetic failure and ensure adequate support, which anatomical landmark must be identified as a mandatory requirement for the posterior extension of the mandibular denture base?
Correct
Correct: The retromolar pad is a key landmark in mandibular complete denture fabrication. It is composed of stable tissue (glandular tissue, muscle fibers) and the underlying bone is resistant to resorption. Capturing it ensures the denture has adequate support and that the posterior border is correctly placed, which is vital for the long-term success of the prosthesis and minimizing patient complaints.
