1. 1An adult referred for a wrist orthosis has a neurological diagnosis but discusses the proposed treatment coherently. Which finding determines capacity to consent under OPC guidance?

   1. A.Ability to understand the treatment information and appreciate the consequences of the decisionCorrect answer: A
   2. B.Ability to perform personal care independently and travel to the appointment without assistance
   3. C.Ability to sign a written authorization and reproduce the treating clinician’s explanation verbatim
   4. D.Ability to agree with the recommended treatment and identify the clinician’s preferred device

   Explanation: OPC states, "A person is capable with respect to a treatment if the person is able to understand the information that is relevant to making a decision about the treatment and is able to appreciate the reasonably foreseeable consequences of a decision or lack of a decision." Capacity concerns understanding and appreciation, rather than functional independence, verbatim recall, or agreement with the recommendation.

2. 2At an orthotic appointment, an adult develops a newly hot, swollen knee with fever and marked motion loss. Which referral priority is appropriate?

   1. A.Prompt medical assessment to exclude joint infectionCorrect answer: A
   2. B.Routine medical review after a trial of bracing
   3. C.Routine rehabilitation review after swelling settles
   4. D.Prompt fabrication review before medical reassessment

   Explanation: The source states, "Acute monoarticular joint pain requires rapid diagnosis because infectious (septic) arthritis requires rapid treatment" The acute presentation requires medical assessment rather than using an orthosis trial as the diagnostic test. This does not ask the orthotist to perform arthrocentesis or prescribe antibiotics.

3. 3During limb preparation, a patient needs a garment-based intervention with repeated adjustments or replacements as limb volume decreases. Which CPOT intervention includes this continuing provision?

   1. A.Serial casting
   2. B.Compression therapyCorrect answer: B
   3. C.Joint mobilization
   4. D.Desensitization therapy

   Explanation: CPOT states, "May involve multiple sessions for adjustments/ replacement garments to ensure sufficient compression as body segment volume decreases." This description belongs to compression therapy: garment fit is adjusted or the garment replaced to maintain sufficient compression. Serial casting, joint mobilization and desensitization are genuine therapeutic interventions with different methods.

4. 4At follow-up, a patient reports wearing an orthosis for 3 hours in the morning and 2 hours in the evening. The prescribed total was 8 hours. What percentage of the prescribed daily time was reported?

   1. A.25%
   2. B.37.5%
   3. C.62.5%Correct answer: C
   4. D.20.8%

   Explanation: The source states, "previous prosthetic/orthotic history (including compliance)" Reported wear = 3 + 2 = 5 hours. Adherence by time = 5/8 × 100 = 62.5%. Counting only the evening gives 25%; only the morning gives 37.5%; dividing by a full 24-hour day gives 20.8%. The denominator is the prescribed eight hours.

5. 5A service offers an orthotist a payment solely for each patient referred. Which response follows the OPC Canons?

   1. A.Retain the referral funds as a clinic marketing allowance
   2. B.Retain the referral funds as a clinical administration credit
   3. C.Distribute the referral funds through an existing partnership
   4. D.Decline the referral funds under the OPC Canons of conductCorrect answer: D

   Explanation: The source states, "directly or indirectly request, receive or participate in dividing, transferring, assigning, or rebating any funds derived from a referral of a patient" Renaming or sharing the referral-derived payment does not change its source. The Canons prohibit both direct and indirect arrangements.

   Reference: OPC Canons of Ethical Conduct — §4.06, p.10

6. 6After an initial discussion and consent for an AFO, an orthotist proposes a substantially different treatment option. What consent step does OPC guidance require?

   1. A.Confirm the existing authorization when the orthosis is delivered to the patient
   2. B.Obtain consent again through discussion of the newly proposed treatment optionCorrect answer: B
   3. C.Obtain consent again when the routine follow-up evaluation has been completed
   4. D.Confirm the existing authorization when the referring prescriber approves the change

   Explanation: OPC states, "If the condition of the patient significantly changes or if the OPC Member proposes a different treatment option, then consent should be obtained again." The new option triggers renewed consent before proceeding; delivery, follow-up, or prescriber approval does not replace this discussion.

7. 7A custom orthosis is requested without a prescription or referral. What must an OPC clinician obtain before providing the custom device?

   1. A.Authorization from the component supplier
   2. B.Authorization from the patient’s employer
   3. C.A prescription or referral from an appropriately licensed prescriberCorrect answer: C
   4. D.A prescription or referral from the device fabricator

   Explanation: The source states, "The OPC Credential Holder must obtain a prescription or referral from a physician or appropriately licensed healthcare prescriber before providing any custom orthotic or prosthetic device to a patient." The requirement concerns a licensed healthcare prescriber. Supplier, employer and fabricator approvals have other roles and do not replace that authorization.

   Reference: OPC Canons of Ethical Conduct — §3.01, p.7

8. 8During preparation for orthotic reapplication, which wound-care situation falls within CPOT’s stated limited wound-care activity?

   1. A.An incision from foot-reconstruction surgery
   2. B.A pressure injury from prolonged bed immobility
   3. C.An ulcer from peripheral arterial insufficiency
   4. D.A pressure injury from the orthotic interfaceCorrect answer: D

   Explanation: CPOT states that this wound-care activity "applies strictly to skin issues related directly to prosthetic/orthotic use." Pressure injury caused by the orthotic interface directly satisfies that relationship. The other stated mechanisms do not establish an orthosis-caused skin issue; they require assessment and care appropriate to their causes.

   Reference: OPC Compendium for Prosthetic and Orthotic Treatment — §6.0, Wound care, p.38

9. 9An orthosis improves a patient’s measured walking performance, but the patient still reports poor comfort. How should these findings be interpreted during outcome review?

   1. A.Use the walking result as a proxy for comfort
   2. B.Retain separate findings for function and comfortCorrect answer: B
   3. C.Use the comfort report as a proxy for walking
   4. D.Record the walking result as overall satisfaction

   Explanation: CPOT states, "The evaluation can span the following scales: pain, functional mobility, alignment, transfers, skin function, upper extremity, ADL, recreation/community or leisure activities, adaptive technology and distress/patient’s overall well-being." Functional improvement and discomfort can coexist and should remain separate findings. A mobility result does not establish comfort or overall satisfaction, and a comfort report does not substitute for measured walking performance.

10. 10An employer uninvolved in a patient’s care requests confidential clinical information. There is no court order or welfare-based need to disclose. What authorization does the OPC confidentiality clause require?

    1. A.Prior written consent from the patient or legal guardianCorrect answer: A
    2. B.Prior verbal consent from the patient or legal guardian
    3. C.A written request from the patient’s employer
    4. D.A verbal request from the patient’s referring clinician

    Explanation: The source states, "may not be communicated to any third party not involved in the patient’s care, without the prior written consent of the patient or patient’s legal guardian." The specified outside-care disclosure requires prior written consent. The stated exceptions do not apply in this case.
