AOA Board Certification Exam (General) — Questions and Answers

Question 1: Which medication class is considered first-line pharmacological therapy for type 2 diabetes mellitus?

Sulfonylureas
Insulin
Metformin (biguanide) (Correct answer)
DPP-4 inhibitors

Correct answer: Metformin (biguanide)

Metformin is the recommended first-line pharmacological treatment for type 2 diabetes due to its efficacy, safety profile, cardiovascular benefits, and low cost.

Question 2: A patient is being treated with muscle energy technique for a left-rotated T7 vertebra. The physician instructs the patient to attempt to rotate to the left against the physician's unyielding counterforce. This is an example of which type of muscle contraction?

Isometric (Correct answer)
Isokinetic
Isotonic
Eccentric

Correct answer: Isometric

An isometric contraction is one in which the muscle contracts, but there is no change in its length. In this muscle energy technique scenario, the patient is generating a force against an immovable object (the physician's counterforce), resulting in increased muscle tension without joint movement. This is the classic setup for an isometric contraction used in post-isometric relaxation muscle energy techniques.

Question 3: What is the recommended screening interval for colorectal cancer using colonoscopy in average-risk adults starting at age 45?

Every 3 years
Every 2 years
Every 10 years (Correct answer)
Every 5 years

Correct answer: Every 10 years

Current guidelines recommend colonoscopy every 10 years for average-risk adults beginning at age 45 for colorectal cancer screening.

Question 4: Which laboratory finding is most characteristic of disseminated intravascular coagulation (DIC)?

Isolated thrombocytopenia with normal PT
Decreased D-dimer with elevated fibrinogen
Elevated fibrinogen with normal PT
Elevated D-dimer with prolonged PT and PTT (Correct answer)

Correct answer: Elevated D-dimer with prolonged PT and PTT

DIC is characterized by elevated D-dimer (reflecting fibrinolysis), prolonged PT/PTT, and decreased fibrinogen due to widespread coagulation factor consumption.

Question 5: What is the recommended Pap smear screening frequency for women aged 21–29 with no prior abnormal results?

Every 3 years (Correct answer)
Annually
Every 5 years
Every 2 years

Correct answer: Every 3 years

Current guidelines recommend Pap smear screening every 3 years for women aged 21–29 without prior abnormal results.

Question 6: According to Section 3 of the AOA Code of Ethics, the physician-patient relationship must be founded on mutual trust and respect. This principle directly implies which of the following?

The patient must follow all physician recommendations without question.
The physician is obligated to continue care indefinitely once a relationship is established.
The patient must have complete freedom to choose their physician. (Correct answer)
The physician must agree to treat all individuals who present to their office for care.

Correct answer: The patient must have complete freedom to choose their physician.

Section 3 of the AOA Code of Ethics explicitly states, 'The patient, therefore, must have complete freedom to choose her/his physician.' While the physician also has the freedom to choose which patients to serve (outside of emergencies or discriminatory reasons), the foundation of trust requires that the patient's choice and autonomy in selecting their provider is respected. The code does not obligate a physician to treat everyone or continue care indefinitely (rules for withdrawal of care exist), nor does it remove the patient's right to question recommendations.

Question 7: Which interpretation of an arterial blood gas — pH 7.28, PaCO2 55 mmHg, HCO3 24 mEq/L — is correct?

Respiratory alkalosis
Metabolic acidosis
Mixed metabolic and respiratory acidosis
Respiratory acidosis (Correct answer)

Correct answer: Respiratory acidosis

Low pH with elevated PaCO2 and normal bicarbonate indicates an acute respiratory acidosis without metabolic compensation.

Question 8: Why is it important for osteopathic physicians to take a holistic approach to patient care?

To treat only the physical aspects of the disease.
To address all aspects of a patient's health (Correct answer)
To reduce patient care time.
To focus solely on physical rehabilitation.

Correct answer: To address all aspects of a patient's health

A holistic approach ensures that all aspects of a patient's health, including physical, mental, and emotional factors, are addressed, leading to better health outcomes.

Question 9: A patient with suspected myocardial infarction presents 6 hours after symptom onset. Which biomarker is most sensitive and specific at this time point?

Myoglobin
Troponin I (Correct answer)
CK-MB
LDH

Correct answer: Troponin I

Troponin I remains elevated for 7–10 days and is the most sensitive and specific cardiac biomarker from 4–6 hours after MI onset.

Question 10: Which thyroid function test pattern is consistent with subclinical hypothyroidism?

Elevated TSH, elevated free T4
Low TSH, low free T4
Elevated TSH, normal free T4 (Correct answer)
Normal TSH, low free T4

Correct answer: Elevated TSH, normal free T4

Subclinical hypothyroidism is defined by elevated TSH with a normal free T4, indicating early thyroid insufficiency without overt hormonal deficiency.

Question 11: A 65-year-old patient is hospitalized with community-acquired pneumonia. In addition to antibiotics, which osteopathic manipulative treatment (OMT) would be most appropriate to improve lymphatic drainage and respiratory mechanics?

High-velocity, low-amplitude (HVLA) to the lumbar spine
Balanced ligamentous tension of the sacrum
Thoracic lymphatic pump and rib raising (Correct answer)
Cervical muscle energy to address C3-C5 dysfunction

Correct answer: Thoracic lymphatic pump and rib raising

For respiratory infections like pneumonia, OMT focuses on improving respiratory mechanics and fluid movement. [6, 9] Thoracic lymphatic pump techniques are specifically designed to enhance lymphatic circulation, aiding in the clearance of inflammatory products and pathogens. [5, 9] Rib raising improves the motion of the rib cage, decreases sympathetic tone to the lungs, and enhances the pressure gradients that drive lymphatic flow. [5, 29] While other treatments might address secondary dysfunctions, thoracic pump and rib raising directly target the primary area of concern.

Question 12: What is the primary benefit of using OMM for treatment?

It provides instant pain relief.
It allows for faster healing with drugs.
It enhances natural healing without drugs or invasive procedures (Correct answer)
It eliminates the need for all medications.

Correct answer: It enhances natural healing without drugs or invasive procedures

The primary benefit of OMM lies in its non-invasive, drug-free approach to healthcare. By focusing on the body's innate ability to heal and self-regulate, OMM techniques help restore proper physiological function and reduce mechanical stress. This allows the body to recover more effectively from injury or illness, often reducing the need for pharmaceutical interventions or invasive surgical procedures.

Question 13: A 68-year-old man has a serum PSA of 8.2 ng/mL. Which factor would most increase the suspicion for prostate cancer over benign prostatic hyperplasia (BPH)?

Free PSA fraction of 8% (Correct answer)
Symmetric prostate enlargement on DRE
Age-adjusted PSA within normal range
PSA velocity of 0.5 ng/mL/year

Correct answer: Free PSA fraction of 8%

A low free PSA fraction (<10%) suggests a higher proportion of bound PSA, which correlates with malignancy rather than the diffuse PSA release seen in BPH.

Question 14: How does OMM help improve circulation?

It involves physical exercise.
It relies on prescription drugs.
It uses manual techniques to stimulate blood and lymph flow (Correct answer)
It involves using machines to stimulate circulation.

Correct answer: It uses manual techniques to stimulate blood and lymph flow

OMM techniques are specifically designed to improve the body's circulatory and lymphatic systems. By applying gentle pressure, stretching, and rhythmic movements to tissues, osteopathic physicians can release fascial restrictions and muscle tension that may impede fluid flow. This manual stimulation helps enhance the delivery of oxygen and nutrients to tissues while facilitating the removal of waste products, thereby improving overall circulation and reducing swelling.

Question 15: What is the primary goal of HEDIS (Healthcare Effectiveness Data and Information Set) measures?

To assess individual physician performance
To set hospital reimbursement rates

Correct answer: To measure and compare health plan performance

HEDIS measures are used to evaluate and compare the performance of health plans on key dimensions of care and service.

Question 16: A family medicine osteopathic physician wants to improve glycemic control in their panel of patients with Type 2 Diabetes. Which of the following represents the MOST effective use of information technology for this Practice-Based Learning and Improvement project?

Watching online videos of other physicians discussing diabetes management.
Using the electronic health record (EHR) to generate a report of all diabetic patients with an HbA1c above 9.0% to target them for intervention. (Correct answer)
Reading a blog post about a new diabetes medication.
Setting up a social media page for the practice to share general diabetes facts.

Correct answer: Using the electronic health record (EHR) to generate a report of all diabetic patients with an HbA1c above 9.0% to target them for intervention.

A key component of PBLI is using technology to systematically analyze one's own practice data. The EHR is a powerful tool for this purpose. Generating a specific report to identify patients who are not meeting clinical goals allows the physician to analyze their patient panel, identify care gaps, and implement targeted quality improvement initiatives, which is central to PBLI.

Question 17: How does osteopathic treatment improve circulation?

By manipulating the bones to stimulate blood flow.
By addressing musculoskeletal dysfunctions that impede circulation (Correct answer)
By using medications to improve circulation.
By increasing blood volume directly.

Correct answer: By addressing musculoskeletal dysfunctions that impede circulation

Osteopathic treatment aims to enhance circulation by addressing musculoskeletal dysfunctions that may impede the flow of blood, helping to optimize body function.

Question 18: An 82-year-old patient with end-stage COPD and a valid Do Not Resuscitate (DNR) order experiences a respiratory arrest in the hospital. The patient's daughter, who is not the legal healthcare proxy, arrives and frantically demands that 'everything be done' to save her father. What is the most ethically and legally sound immediate action for the osteopathic physician?

Honor the patient's advance directive and refrain from initiating resuscitation. (Correct answer)
Initiate a 'slow code' to appease the daughter while respecting the patient's wishes.
Ask the daughter to find the legal healthcare proxy before making a decision.
Immediately begin full resuscitation efforts as requested by the family member.

Correct answer: Honor the patient's advance directive and refrain from initiating resuscitation.

The principle of patient autonomy is paramount. A valid advance directive, such as a DNR, is the direct expression of the patient's wishes and must be honored, even in the face of family distress. Initiating a 'slow code' is unethical, and overriding the directive based on a non-proxy family member's request violates the patient's rights. While locating the proxy is important for other decisions, the DNR order is a direct physician order that stands on its own in an arrest situation.

Question 19: Which of the following activities best demonstrates an osteopathic physician's engagement in the self-evaluation component of Practice-Based Learning and Improvement (PBLI)?

Attending a national conference to fulfill CME requirements.
Reading the latest issue of the Journal of the American Osteopathic Association (JAOA).
Teaching osteopathic manipulative treatment to medical students.
Reviewing personal patient outcome data against national benchmarks. (Correct answer)

Correct answer: Reviewing personal patient outcome data against national benchmarks.

The self-evaluation component of PBLI involves the systematic investigation and analysis of one's own practice performance. Comparing personal patient outcomes to established national benchmarks is a direct, objective method to identify knowledge or performance gaps and set goals for improvement.

Question 20: How should professionals apply professional standards and ethics in daily practice?

A chronic, stable herniated disc
Osteoporosis
Somatic dysfunction with a hard end-feel
Vertebral artery disease (Correct answer)

Correct answer: Vertebral artery disease

Diagnosed vertebral artery disease is an absolute contraindication to cervical HVLA. The rotational and extension components of a cervical HVLA thrust can compromise an already diseased vertebral artery, potentially leading to vertebrobasilar insufficiency, stroke, or dissection. The other options are generally considered relative contraindications that require careful clinical judgment.

Question 39: An osteopathic physician is invited by a pharmaceutical company to an educational dinner at an upscale restaurant to learn about a new medication for hypertension. The company will pay for the physician's meal. Which of the following is most consistent with the AOA's ethical guidelines regarding such events?

The physician may accept the invitation and meal, provided the event is primarily educational and the meal is modest. (Correct answer)
The physician may accept the invitation but should pay for their own meal to eliminate any conflict of interest.
The physician should only accept if the company also provides educational materials, such as textbooks, of a similar value to the meal.
The physician should decline all such invitations to avoid any appearance of impropriety.

Correct answer: The physician may accept the invitation and meal, provided the event is primarily educational and the meal is modest.

The AOA Code of Ethics and interpretations from similar bodies like the AMA permit physicians to attend educational events sponsored by industry. The key ethical stipulations are that the event's main purpose must be educational, the hospitality (like a meal) must be modest, and the physician's attendance should not be contingent on prescribing the company's products. Declining all events may be overly cautious, while paying for the meal, though a safe option, is not explicitly required if the event meets the primary educational and modesty criteria.

In this scenario, using technology like e-consults and telehealth leverages the broader healthcare system to bring specialized expertise to a resource-limited area, overcoming geographical barriers and ensuring the patient receives appropriate care.

Question 44: In epidemiology, what does the term 'incidence rate' measure?

Proportion of deaths among those with a disease
Rate of new cases developing over a specified time period (Correct answer)
Total number of existing cases in a population
Percentage of the population exposed to a risk factor

Correct answer: Rate of new cases developing over a specified time period

Incidence rate measures the rate at which new cases of a disease develop in a defined population over a specified time period.

Question 45: Which dangerous drug interaction occurs when SSRIs are combined with MAOIs?

Reduced antidepressant efficacy
Serotonin syndrome (Correct answer)
Increased risk of bleeding
Hypertensive crisis

Correct answer: Serotonin syndrome

Combining SSRIs with MAOIs causes serotonin syndrome, a potentially life-threatening condition characterized by agitation, hyperthermia, and neuromuscular abnormalities.

Question 46: A physical examination of a patient with left-sided low back pain reveals that the left Anterior Superior Iliac Spine (ASIS) is inferior and the left Posterior Superior Iliac Spine (PSIS) is superior compared to the right side. These findings are most consistent with which somatic dysfunction?

Left posterior innominate rotation
Left inflare
Left anterior innominate rotation (Correct answer)
Left superior innominate shear

Correct answer: Left anterior innominate rotation

An anterior innominate rotation is characterized by the ilium rotating forward on the sacrum around the inferior transverse axis. This movement causes the ASIS on the affected side to move inferiorly and the PSIS to move superiorly relative to the contralateral side.

Question 47: Which diuretic class commonly causes hypokalemia as a significant adverse effect?

Potassium-sparing diuretics
Thiazide diuretics (Correct answer)
Osmotic diuretics

Correct answer: Oral vancomycin

Current IDSA guidelines recommend oral vancomycin or fidaxomicin as preferred therapy for initial non-severe CDI over metronidazole.

Question 50: Rational treatment in the osteopathic model is based upon an understanding and integration of which three principles?

Body unity, self-regulation, and the interrelationship of structure and function (Correct answer)
Pathology, pharmacology, and surgical intervention
Mind, spirit, and emotional well-being
Evidence-based medicine, patient preference, and clinical expertise

Correct answer: Body unity, self-regulation, and the interrelationship of structure and function

The fourth tenet of osteopathic medicine states that rational treatment is based upon the application of the other three core principles: 1) the body is a unit; the person is a unit of body, mind, and spirit; 2) the body is capable of self-regulation and self-healing; and 3) structure and function are reciprocally interrelated. [4, 12, 24] This foundational concept guides the osteopathic physician's diagnostic and therapeutic approach.

Question 51: What is the mechanism of action of benzodiazepines in producing CNS depression?

Enhance GABA-A receptor chloride conductance (Correct answer)
Inhibit serotonin reuptake
Block dopamine D2 receptors
Block NMDA glutamate receptors

Correct answer: Enhance GABA-A receptor chloride conductance

Benzodiazepines enhance the effect of GABA at GABA-A receptors by increasing the frequency of chloride channel opening, producing CNS depression.

Question 52: Why is OMM considered a holistic treatment?

OMM is used only to treat specific injuries.
OMM focuses only on physical health.
OMM is a holistic approach that treats the entire person (Correct answer)
OMM focuses solely on pain relief.

Correct answer: OMM is a holistic approach that treats the entire person

OMM is considered holistic because it views the body as an integrated unit, where all systems are interconnected and influence each other's health. Rather than just treating symptoms or specific injuries, osteopathic physicians use OMM to address the root causes of dysfunction by considering the patient's physical, mental, and emotional well-being. This comprehensive perspective aims to restore the body's natural ability to heal and maintain overall health.

Question 53: Which of the following osteopathic manipulative techniques is classified as both indirect and passive?

High-Velocity, Low-Amplitude (HVLA)
Direct Myofascial Release
Muscle Energy Technique (MET)
Facilitated Positional Release (FPR) (Correct answer)

Correct answer: Facilitated Positional Release (FPR)

Facilitated Positional Release (FPR) is an indirect technique because the dysfunctional body part is moved away from the restrictive barrier into a position of ease. It is also a passive technique because the physician performs the maneuver without any active assistance from the patient. MET is an active technique, while HVLA and direct myofascial release are direct techniques.

Question 54: A patient expresses concern about the high cost of a newly prescribed medication and states they may not be able to afford it. Which of the following responses by the osteopathic physician best exemplifies the principle of cost-conscious care within Systems-Based Practice?

Suggesting the patient use a credit card to pay for the prescription.
Informing the patient that the medication is essential and they must find a way to pay for it.
Providing a few free samples from the office to start the therapy.
Exploring therapeutically equivalent, lower-cost alternatives and engaging a case manager to investigate patient assistance programs. (Correct answer)

Correct answer: Exploring therapeutically equivalent, lower-cost alternatives and engaging a case manager to investigate patient assistance programs.

Systems-Based Practice includes practicing cost-effective health care and assisting patients in dealing with system complexities. This response directly addresses the patient's barrier to care by considering clinical alternatives (cost-effectiveness) and utilizing system resources (case manager, assistance programs) to find a sustainable solution.

Correct answer: It is a condition where the musculoskeletal system is functioning improperly

Somatic dysfunction refers to impaired or altered function of the body’s musculoskeletal system, which osteopaths aim to diagnose and treat to promote overall health.

Question 57: Which finding on peripheral blood smear is most consistent with thrombotic thrombocytopenic purpura (TTP)?

Schistocytes (helmet cells) (Correct answer)
Spherocytes
Hypersegmented neutrophils
Teardrop cells

Correct answer: Schistocytes (helmet cells)

Schistocytes (fragmented red cells/helmet cells) result from mechanical destruction of RBCs by platelet thrombi in microvasculature, hallmark of TTP.

Question 58: How can effective communication improve patient care?

It increases patient dissatisfaction.
It builds trust and ensures informed decision-making (Correct answer)
It reduces treatment adherence.
It makes treatment less personalized.

Correct answer: It builds trust and ensures informed decision-making

Question 59: An osteopathic physician performs an evaluation and management (E/M) service and OMT for 3-4 body regions during the same visit for an established patient with acute back pain. To ensure proper billing and documentation, which of the following is required?

Using a separate and distinct diagnosis for the E/M service and the OMT.
Appending a -25 modifier to the E/M code to indicate a significant, separately identifiable service. (Correct answer)
Documenting only the OMT techniques used and the regions treated.
Billing only for the OMT, as it was the primary procedure performed.

Correct answer: Appending a -25 modifier to the E/M code to indicate a significant, separately identifiable service.

When a significant, separately identifiable E/M service is performed on the same day as a procedure like OMT, the -25 modifier should be appended to the E/M code. The documentation must support that the E/M service went above and beyond the usual pre-service and post-service work inherent to the OMT procedure. It is not necessary to have different diagnoses for the E/M and OMT services. Comprehensive documentation for both services is essential for compliance.

Question 60: A 45-year-old patient with chronic obstructive pulmonary disease (COPD) is being managed with standard medical therapy. As part of a holistic management plan, the osteopathic physician incorporates OMT. Which of the following is the PRIMARY goal of using OMT in the management of this patient's chronic condition?

To improve the biomechanical function of the respiratory system and support self-healing mechanisms. (Correct answer)
To cure the underlying lung pathology of COPD.
To exclusively address the patient's anxiety related to their diagnosis.
To replace the need for inhalers and other medications.

Correct answer: To improve the biomechanical function of the respiratory system and support self-healing mechanisms.

In chronic disease management, OMT serves as a complementary therapy. For a patient with COPD, the primary goal of OMT is not to cure the irreversible lung damage but to optimize function. This includes improving the mobility of the ribs, spine, and diaphragm to enhance respiratory mechanics, promoting lymphatic drainage, and supporting the body's inherent ability to self-regulate and heal. OMT aims to improve quality of life and physiological function alongside, not in place of, standard medical care.

Question 61: What is a key component of clinical knowledge in patient care?

Understanding only physical therapies.
Understanding diseases, medications, and diagnostic principles (Correct answer)
Being able to memorize medical terminology.
Knowing how to perform surgeries.

Clinical knowledge involves understanding the pathophysiology of diseases, the pharmacology of medications, and the principles of diagnostic testing to provide effective care.

Question 62: A 45-year-old male presents with chronic epigastric pain and is diagnosed with peptic ulcer disease. Based on an understanding of viscerosomatic reflexes, the osteopathic physician would expect to find facilitated segments and tissue texture changes MOST prominently at which of the following spinal levels?

T10-T11
T12-L2
T1-T4
T5-T9 (Correct answer)

Correct answer: T5-T9

The sympathetic innervation to the upper gastrointestinal tract, including the stomach and duodenum, originates from the T5-T9 spinal cord levels. Visceral pathology, such as peptic ulcer disease, can cause a sustained increase in afferent signals to this spinal cord region, resulting in a viscerosomatic reflex. This manifests as palpable somatic dysfunction (facilitation, tenderness, tissue changes) in the paraspinal tissues of T5-T9.

Question 63: Which beta-blocker is cardioselective and preferentially acts on beta-1 receptors?

Propranolol
Labetalol
Metoprolol (Correct answer)
Carvedilol

Correct answer: Metoprolol

Metoprolol is a cardioselective beta-1 blocker that preferentially blocks cardiac beta-1 receptors, making it relatively safer in patients with reactive airway disease.

Question 64: Which of the following is a core tenet of osteopathic medicine?

Structure and function are only minimally interrelated.
Pharmacological intervention is the primary modality for restoring health.
The body is capable of self-regulation, self-healing, and health maintenance. (Correct answer)
The body's systems are independent and should be treated as separate entities.

Correct answer: The body is capable of self-regulation, self-healing, and health maintenance.

One of the four primary tenets of osteopathic medicine is that the body possesses inherent mechanisms for self-regulation, self-healing, and maintaining health. [4, 24] The other tenets are: 1) The body is a unit; the person is a unit of body, mind, and spirit; 2) Structure and function are reciprocally interrelated; and 3) Rational treatment is based on an understanding of these basic principles. [12, 24] The other answer choices directly contradict these core philosophical pillars of osteopathy.

Question 65: What is the first-line and most critical treatment for anaphylaxis?

Diphenhydramine (Benadryl) IV
Systemic corticosteroids
Beta-2 agonist inhaler

It avoids involving the patient in decisions.
It focuses solely on medical treatments.
It focuses on a fast diagnosis.

Correct answer: It ensures that the patient’s needs and preferences guide their care

Patient-centered care focuses on understanding and addressing the patient’s preferences, needs, and values, ensuring that the patient is an active participant in their care decisions.

Question 70: How does OMM contribute to the body’s immune function?

OMM has no effect on immune function.
OMM increases inflammation.
OMM enhances immune function by improving circulation and reducing stress (Correct answer)
OMM works by suppressing immune responses.

Correct answer: OMM enhances immune function by improving circulation and reducing stress

OMM contributes to immune function through several mechanisms. By improving lymphatic drainage and blood circulation, OMM helps ensure immune cells and antibodies can effectively reach all parts of the body. Additionally, by reducing musculoskeletal tension and promoting relaxation, OMM can lower stress levels, which are known to suppress the immune system, thereby indirectly bolstering the body's defenses.

Question 71: What ethical standard governs professional standards and ethics practice?

Question 72: An osteopathic physician is a solo practitioner in a small town. A long-time patient, who is a professional baker, frequently brings elaborate cakes and pastries to the office for the physician and staff as a token of gratitude. According to general medical ethics principles, which factor is MOST important for the physician to consider when deciding whether to continue accepting these gifts?

The physician's personal and staff's preference for the types of pastries being offered.
The potential for the gifts to influence professional judgment or create a sense of obligation. (Correct answer)
The monetary value of the baked goods and whether they exceed a certain limit.
Whether other patients in the waiting room see the gifts being delivered.

Correct answer: The potential for the gifts to influence professional judgment or create a sense of obligation.

While the value of a gift is a consideration, the most critical ethical factor is whether the gift has the potential to compromise the physician's objectivity or influence medical care. Accepting gifts, even those of modest value, can blur professional boundaries and create a perception of favoritism or a sense of obligation, which must be carefully managed to maintain the integrity of the physician-patient relationship.

Question 73: What is the primary pharmacological concern when prescribing NSAIDs to elderly patients?

Increased risk of GI bleeding, renal impairment, and cardiovascular events (Correct answer)
Risk of respiratory depression

The right to have complete freedom to choose their physician. (Correct answer)
The right to demand specific treatments, including those not medically indicated.
The right to access the physician's personal health information.

Correct answer: The right to have complete freedom to choose their physician.

Section 3 of the AOA Code of Ethics explicitly states that the physician-patient relationship is founded on mutual trust, cooperation, and respect, and therefore, 'The patient...must have complete freedom to choose her/his physician.' While physicians also have the right to choose whom they serve (outside of emergencies or discrimination), the foundational principle of trust directly empowers the patient's autonomy in selecting their provider. The other options are not supported by this ethical principle.

Question 88: A physician partner in an osteopathic group practice has been observed by colleagues to have slurred speech and an unsteady gait on multiple occasions. An initial confidential conversation with the partner was met with denial and hostility. According to the AOA Code of Ethics, what is the most appropriate next step for the concerned physicians?

Immediately report their concerns to the appropriate authority, such as the state physician health program or the state licensing board. (Correct answer)
Continue to monitor the partner's behavior while covering any patient care duties they may be unable to perform.
Organize an intervention with the partner's family to address the issue privately.
Inform the office manager to begin documenting performance issues for potential dismissal.

Correct answer: Immediately report their concerns to the appropriate authority, such as the state physician health program or the state licensing board.

The AOA Code of Ethics obligates physicians to report colleagues who are impaired or incompetent to protect the public and ensure patient safety. Once a direct, private approach has failed, the next ethical responsibility is to report the concern to an official body, such as a state's physician health program (PHP) or the licensing board, which is equipped to investigate and intervene appropriately. Ignoring the problem or handling it through non-official channels fails to meet the primary ethical duty of protecting patients from potential harm.

Question 89: Which direct oral anticoagulant (DOAC) does NOT require routine INR monitoring?

Low molecular weight heparin in severe renal failure

N-acetylcysteine (NAC) is the antidote for acetaminophen overdose, replenishing glutathione stores to prevent hepatotoxic accumulation of the NAPQI metabolite.

Question 119: What quality assurance measure supports core concepts and principles?

Regular self-assessment, peer review, and adherence to established standards (Correct answer)
Quality checks are unnecessary for experienced professionals
Annual review is sufficient
Quality only matters for new practitioners

Correct answer: Regular self-assessment, peer review, and adherence to established standards

Ongoing quality assurance through self-assessment, peer review, and standards adherence ensures continuous improvement.

Question 120: What is somatic dysfunction?

It is a normal variation in the body's function.
It is an altered function in the musculoskeletal system (Correct answer)
It is a dysfunction corrected through surgery.
It is unrelated to overall health.

Correct answer: It is an altered function in the musculoskeletal system

Somatic dysfunction is an impaired or altered function of the body’s musculoskeletal system, which osteopaths aim to diagnose and treat using hands-on techniques.

Question 121: A 58-year-old male with a history of cholelithiasis presents with right-sided, mid-thoracic back pain and tenderness. On osteopathic structural exam, you note tissue texture changes and restriction of motion at the T5-T9 vertebral levels on the right. Which phenomenon BEST explains these somatic findings?

Somatovisceral reflex
Chapman's points
Referred pain pathway
Viscerosomatic reflex (Correct answer)

Correct answer: Viscerosomatic reflex

The viscerosomatic reflex is a phenomenon where visceral dysfunction leads to somatic findings, such as muscle hypertonicity, tissue texture changes, and pain, in segmentally related areas of the musculoskeletal system. [2] The gallbladder's visceral afferent nerves synapse in the spinal cord at the T5-T9 levels, causing facilitation and somatic manifestations in the corresponding paraspinal tissues. [2, 10] A somatovisceral reflex is the opposite, where a somatic issue causes visceral dysfunction. Chapman's points are specific anterior and posterior points related to visceral dysfunction but are a distinct diagnostic finding. Referred pain is a more general term, while viscerosomatic reflex describes the specific neurological mechanism.

Question 122: A 78-year-old male is discharged from the hospital after a complicated stay for pneumonia and a COPD exacerbation. To prevent readmission, which of the following sets of actions by the osteopathic physician best demonstrates effective Transitional Care Management (TCM) as an application of Systems-Based Practice?

Scheduling a follow-up appointment for 30 days post-discharge.
Contacting the patient within two business days, performing medication reconciliation, and coordinating with a home health nurse. (Correct answer)
Advising the patient to call the office if problems arise and ensuring their prescriptions were sent to the pharmacy.
Providing the patient with a standard printout of discharge instructions only.

Correct answer: Contacting the patient within two business days, performing medication reconciliation, and coordinating with a home health nurse.

Effective Transitional Care Management (TCM), a key component of Systems-Based Practice, involves a structured set of activities to ensure a safe transition from an inpatient setting back to the community. This includes prompt follow-up contact (within two business days), medication reconciliation to prevent errors, and coordination with other system resources like home health services to manage the patient's complex needs and prevent readmission.

Question 123: A 72-year-old male with a long history of COPD presents for osteopathic manipulative treatment to improve respiratory function. To specifically address somatic dysfunction related to the diaphragm, the osteopathic structural exam should primarily focus on which vertebral levels?

C3-C5 (Correct answer)
T10-L2
T5-T9
T1-T4

Correct answer: C3-C5

The diaphragm, the primary muscle of respiration, receives its motor innervation exclusively from the phrenic nerve. The phrenic nerve originates from the anterior rami of cervical spinal nerves C3, C4, and C5. Therefore, identifying and treating somatic dysfunction in the C3-C5 region is crucial for optimizing diaphragm function.

Question 124: How should challenges in core concepts and principles be addressed?

Avoid challenges and stick to familiar tasks
Ignore challenges until they resolve themselves
Delegate all challenges to supervisors
Apply systematic problem-solving, seek expert guidance when needed, and document decisions (Correct answer)

Maintaining patient confidentiality protects the privacy of patients' health information, ensuring trust and respect in the doctor-patient relationship.

Question 126: Which drug is used as an opioid reversal agent in cases of overdose?

Naloxone (Correct answer)
Methadone
Buprenorphine
Naltrexone

Correct answer: Naloxone

Naloxone is a competitive opioid receptor antagonist used for rapid reversal of opioid overdose due to its fast onset and ability to displace opioids from receptors.

Question 127: What is the primary cardiovascular indication for low-dose aspirin (81 mg)?

Antipyretic therapy for fever management
Anti-inflammatory therapy for arthritis
Antiplatelet therapy to prevent thrombotic events (Correct answer)
Analgesic effect for chronic pain

Correct answer: Antiplatelet therapy to prevent thrombotic events

Low-dose aspirin irreversibly inhibits platelet COX-1, reducing thromboxane A2-mediated platelet aggregation to prevent thrombotic cardiovascular events.

Question 128: An osteopathic physician is preparing to perform osteopathic manipulative treatment (OMT) on a new patient for neck pain. Which of the following is an essential component of the informed consent process for this procedure?

Clearly explaining the proposed OMT techniques, potential benefits, common side effects, and rare but serious risks. (Correct answer)
Documenting verbal consent in the patient's chart without a detailed discussion.
Having the patient sign a standardized, generic consent form for manual medicine.
Guaranteeing the patient that the OMT will resolve their pain.

Correct answer: Clearly explaining the proposed OMT techniques, potential benefits, common side effects, and rare but serious risks.

Informed consent is a critical ethical and legal process. For OMT, it must involve a clear discussion of the specific proposed treatment, its expected benefits (e.g., pain relief, improved mobility), potential common side effects (like temporary soreness), and any rare but serious risks (e.g., disc injury, vascular injury). This ensures the patient can make an autonomous and informed decision about their care. Standardized forms may not be sufficient without a specific discussion, guaranteeing results is inappropriate, and simply documenting consent without the discussion is inadequate.

Question 129: How do conflicts of interest affect medical practice?

They make healthcare providers more objective.
They can lead to biased care and undermine trust (Correct answer)
They help improve care efficiency.
They have no effect on patient care.

Correct answer: They can lead to biased care and undermine trust

Conflicts of interest may influence the physician's decisions, leading to biased care and potentially harming the patient’s well-being.

Question 130: What is the role of preventative care in osteopathic practice?

Preventive care is only relevant for senior patients.
Preventive care is not part of osteopathic practice.
Preventive care only includes vaccinations.
Preventive care is central to maintaining overall health (Correct answer)

Correct answer: Preventive care is central to maintaining overall health

Preventive care in osteopathic practice focuses on helping patients maintain health and prevent illness through lifestyle modifications, screenings, and regular assessments.

Question 131: What is the importance of developing a treatment plan in patient care?

To create a personalized approach for treatment and management (Correct answer)
To schedule follow-up visits.
To focus on the patient's emotional health.
To track a patient’s finances.

Correct answer: To create a personalized approach for treatment and management

A treatment plan provides a structured approach to addressing a patient's medical issues, ensuring the best possible outcomes through a personalized and comprehensive plan.

Question 132: A 34-year-old female presents with acute neck pain after a minor car accident. On examination, you palpate warmth, bogginess, and sharp tenderness over the right articular pillar of C4. Motion testing reveals a significant, abrupt restriction of motion. These findings are most consistent with which of the following diagnoses?

Myofascial trigger point
Chronic somatic dysfunction
Acute somatic dysfunction (Correct answer)
Cervical sprain/strain

Correct answer: Acute somatic dysfunction

The TART criteria (Tissue texture changes, Asymmetry, Restriction of motion, Tenderness) are used to diagnose somatic dysfunction. [8] The findings of warmth, bogginess (edema), sharp tenderness, and significant motion restriction are characteristic of an acute somatic dysfunction, often associated with a recent injury. [8, 11] Chronic somatic dysfunction typically presents with coolness, ropiness, and a less intense, dull ache. While a cervical sprain/strain is the general injury, acute somatic dysfunction is the specific osteopathic diagnosis describing the impaired function.

Question 133: A positive tuberculin skin test (TST) with induration ≥ 5 mm is considered positive in which patient group?

Healthcare workers with no known exposure
Patients older than 65
HIV-positive patients (Correct answer)
Individuals from low-prevalence countries

Correct answer: HIV-positive patients

In immunocompromised patients such as those with HIV, a TST induration ≥5 mm is considered positive due to their increased risk of TB reactivation.

Question 134: Which set of laboratory values best characterizes acute pancreatitis?

Elevated lipase >3× ULN, elevated amylase, normal LFTs (Correct answer)
Normal lipase with elevated GGT and AST
Elevated lipase >3× ULN, elevated bilirubin, normal amylase
Elevated amylase only with normal lipase

Correct answer: Elevated lipase >3× ULN, elevated amylase, normal LFTs

Acute pancreatitis is diagnosed when lipase exceeds three times the upper limit of normal, often accompanied by elevated amylase; LFTs may be normal unless gallstones are involved.

Question 135: What is the mechanism of action of ACE inhibitors in treating hypertension?

Promote sodium excretion in the distal tubule
Block beta-adrenergic receptors in the heart
Inhibit conversion of angiotensin I to angiotensin II (Correct answer)
Block calcium channels in vascular smooth muscle

Correct answer: Inhibit conversion of angiotensin I to angiotensin II

ACE inhibitors reduce blood pressure by blocking angiotensin-converting enzyme, preventing formation of angiotensin II which causes vasoconstriction and aldosterone release.

Question 136: Which antibiotic class is contraindicated in pregnant women due to risk of fetal dental discoloration and impaired bone growth?

Macrolides
Tetracyclines (Correct answer)
Cephalosporins
Penicillins

Correct answer: Tetracyclines

Tetracyclines bind calcium in developing fetal teeth and bones, causing permanent discoloration and growth inhibition, making them contraindicated in pregnancy.

Question 137: An osteopathic physician notes a recurring medication error on their hospital service. To address this from a Systems-Based Practice perspective and improve patient safety, what is the MOST appropriate initial action?

Counsel the individual nurse who made the most recent error.
Initiate a root cause analysis (RCA) with an interprofessional team. (Correct answer)
Order all physicians to double-check medication orders before signing.
Write a new policy and place it in the staff lounge.

Correct answer: Initiate a root cause analysis (RCA) with an interprofessional team.

Systems-Based Practice focuses on improving the system to enhance safety, rather than blaming individuals. A root cause analysis (RCA) is a structured, team-based process used to identify underlying system vulnerabilities that led to an adverse event. Involving an interprofessional team ensures that multiple perspectives are considered to find and implement effective, system-level solutions.

Question 138: What is the role of a physician’s duty of care?

To prioritize the physician’s preferences over the patient’s needs.
To ensure the patient’s health and safety through appropriate care (Correct answer)
To provide the best care without considering the patient’s preferences.
To focus on medical profits.

Correct answer: To ensure the patient’s health and safety through appropriate care

A physician’s duty of care involves providing competent and ethical care to patients, ensuring their well-being and minimizing harm.

Question 139: A patient has a serum sodium of 125 mEq/L with low urine osmolality (< 100 mOsm/kg) and low urine sodium (< 20 mEq/L). What is the most likely cause?

Adrenal insufficiency
Hypothyroidism
SIADH
Primary polydipsia (Correct answer)

Correct answer: Primary polydipsia

Dilute urine (low urine osmolality) with low urine sodium in the setting of hyponatremia is classic for primary polydipsia, where excess free water suppresses ADH.

Question 140: How should professional standards and ethics knowledge be maintained and updated?

Through continuous professional development, current literature review, and professional networking (Correct answer)
Initial training provides lifelong competence
Knowledge updates are only needed every five years
Learning stops after certification
