Introduction
,The ABFM + KSA Diabetes Certification Exam assesses the clinical knowledge and decision-making skills essential for
family medicine physicians managing patients with diabetes mellitus. This comprehensive assessment evaluates
proficiency in diagnosis, evidence-based treatment selection, complication screening, and patient-centered counseling
across diverse clinical scenarios. Questions emphasize real-world application, including pharmacologic selection based
on comorbidities, interpretation of monitoring data, and recognition of acute and chronic complications. A significant
portion of items integrate regulatory standards, ethical considerations, and professional guidelines. The exam employs
multiple-choice and scenario-based formats designed to mirror the complexity of primary care practice, requiring
candidates to synthesize foundational science with practical management strategies.
SECTION ONE: QUESTIONS 1–50
1. A 52-year-old male with a body mass index of 31 kg/m² presents for evaluation of fatigue and increased thirst.
His fasting plasma glucose is 128 mg/dL on two separate occasions. According to American Diabetes Association
criteria, which of the following confirms a diagnosis of diabetes mellitus?
A. A single fasting plasma glucose ≥126 mg/dL
B. A random plasma glucose ≥200 mg/dL with classic symptoms
C. A hemoglobin A1c ≥6.5%
D. All of the above
,🟢 Correct Answer: D. All of the above
🔴 Explanation: The American Diabetes Association recognizes multiple diagnostic pathways for diabetes: fasting
plasma glucose ≥126 mg/dL, 2-hour plasma glucose ≥200 mg/dL during oral glucose tolerance testing, hemoglobin
A1c ≥6.5%, or random plasma glucose ≥200 mg/dL with classic symptoms of hyperglycemia. Each criterion, when
met and confirmed as appropriate, establishes the diagnosis.
2. A 45-year-old female with no symptoms undergoes screening and has a hemoglobin A1c of 5.9%. Her fasting
glucose is 108 mg/dL. Which of the following best characterizes her condition?
A. Normal glucose tolerance
B. Prediabetes
C. Diabetes mellitus
D. Inconclusive results requiring repeat testing in one year
🟢 Correct Answer: B. Prediabetes
🔴 Explanation: A hemoglobin A1c of 5.7% to 6.4% falls within the prediabetes range, as does a fasting plasma
glucose of 100 to 125 mg/dL. This patient meets criteria for prediabetes based on both parameters and should
receive counseling on lifestyle modification to prevent progression to diabetes.
3. A 38-year-old obese male with a strong family history of type 2 diabetes asks about his risk. His fasting
glucose is 102 mg/dL. Which intervention has the strongest evidence for preventing or delaying progression to
, diabetes?
A. Metformin 850 mg twice daily
B. Intensive lifestyle modification targeting 7% weight loss and 150 minutes of weekly exercise
C. Pioglitazone 15 mg daily
D. Annual screening only
🟢 Correct Answer: B. Intensive lifestyle modification targeting 7% weight loss and 150 minutes of weekly exercise
🔴 Explanation: The Diabetes Prevention Program demonstrated that intensive lifestyle intervention reduces the
incidence of type 2 diabetes by 58%, outperforming metformin (31% reduction). Lifestyle modification remains the
first-line intervention for prediabetes.
4. A 60-year-old male with type 2 diabetes of 8 years' duration has a hemoglobin A1c of 7.8%. He takes
metformin 1000 mg twice daily. His estimated glomerular filtration rate is 72 mL/min/1.73 m². Which of the
following is the most appropriate next step?
A. Add a sulfonylurea
B. Add an SGLT2 inhibitor with proven cardiovascular benefit
C. Add basal insulin
D. Maximize metformin dose and reassess in 6 months
🟢 Correct Answer: B. Add an SGLT2 inhibitor with proven cardiovascular benefit
