  1. A patient's TSH is elevated at 8.2 mIU/L with a low free T4. Which diagnosis does this pattern most indicate?

    Answer: Primary hypothyroidism

    Elevated TSH with low free T4 is the classic pattern of primary hypothyroidism, where the pituitary compensates for insufficient thyroid hormone by secreting more TSH.

  2. Which finding on urinalysis is most specific for a urinary tract infection?

    Answer: Nitrites and leukocyte esterase

    Nitrites indicate bacterial conversion of urinary nitrates (suggesting gram-negative organisms), while leukocyte esterase indicates pyuria; together they are highly specific for UTI.

  3. A patient's HbA1c is 7.2%. What does this result indicate about their average blood glucose over the past 2–3 months?

    Answer: Above the ADA goal of less than 7% for most adults with diabetes

    An HbA1c of 7.2% confirms diabetes and exceeds the ADA's general target of less than 7%, indicating the need to optimize glucose management.

  4. Which electrocardiographic finding is most diagnostic of an acute ST-elevation myocardial infarction (STEMI)?

    Answer: New ST-segment elevation in two or more contiguous leads

    New ST-segment elevation of ≥1 mm in two or more contiguous leads represents acute transmural myocardial ischemia and is the hallmark ECG finding requiring immediate reperfusion therapy.

  5. What does a positive D-dimer result primarily indicate when evaluating a patient for pulmonary embolism?

    Answer: Indicates fibrin breakdown, suggesting active clot formation or thrombus

    D-dimer is a fibrin degradation product elevated whenever clot is present, but it is nonspecific; a positive result indicates possible thrombus and warrants imaging, not a definitive PE diagnosis.

  6. A patient has a fasting blood glucose of 118 mg/dL. According to ADA criteria, how is this classified?

    Answer: Prediabetes (impaired fasting glucose)

    ADA defines prediabetes as a fasting glucose of 100–125 mg/dL; a value of 118 mg/dL falls within this range, indicating impaired fasting glucose requiring lifestyle intervention.
